Description

FIELD OF THE INVENTION [0001] The present invention relates to a system for preventing fire explosion in a house caused by gas leakage,

The present invention relates to an apparatus and method for preventing a fire explosion in a house caused by a gas leakage, and more particularly, to a system and method for preventing fire explosion in a house caused by a gas leakage, So that when the manager enters the gas leakage area to block the gas valve or open the window, the high pressure accumulated human body accumulated in the body of the human body. To prevent the gas explosion by the static electricity, the static electricity is removed by the conductive material included in the moisture The present invention relates to an apparatus and method for preventing a fire and explosion by discharging electricity.

Generally, in a product using electricity, large and small electric current flows, and the operation of the electric product occurs. Unlike the movement of electric current generated by the flow of a general electric charge, static electricity stays on the surface of the entire body without a flow of electric charge, maintains a constant voltage, and discharges at the moment of discharge to generate a discharge current.

When electrostatic discharge is generated, the electrostatic energy that has been held by the charge is discharged into the discharge space, and unexpected problems may occur due to sparks that may be generated in the discharge. For example, ignition explosion of a combustible gas, electrical shock of a human body, biological damage such as skin breakage, destruction of a semiconductor element or the like, painting and printing failure, photographic light exposure of a photographic film, and malfunction of an electronic device due to electronic noise. In particular, when a large amount of gas or vapor is stagnated in the area where vapor of the petrochemical or oil refinery is generated, as well as in the area where the flammable gas is treated in the general house, a warning is generated by various sensors. Or ventilator drive to remove stagnant gas or vapor. However, a manager who enters and exits the area generates a large amount of static electricity due to human friction, and in a dry weather, static electricity is high, while static electricity generated is not discharged, so that static electricity is stored in a manager's body at a high voltage. Therefore, when the manager having accumulated the high-voltage static electricity enters and leaves the accident facility, when the conductive substance is close to the conductive substance, the static electricity discharged is sparked and gas explosion may occur.

In the case of industrial facilities handling some flammable gases, it is set as an explosion-proof area so that static electricity accumulated in the human body is removed through a static eliminator before entering the explosion-proof area, so that explosion by static electricity can be prevented. However, There is no purchase of a static eliminator, so that when a gas leak occurs, a member of the family moves for ventilation, and a gas explosion fire may be caused by the spark caused by static electricity.

As a countermeasure against gas leaks in existing houses, a gas leakage sensor is installed to detect the leakage of gas and shut off the valve. However, an explosion may occur due to the spark due to the use of electricity when the car is stopped. When the manual valve is shut off, there is a leaked gas even if the automatic shutoff of the valve is made. There is an explosion fire caused by the administrator's body static electricity such as the movement of the manager for discharging the gas, the operation to lower the power switch, the operation to open the window or the curtain There is no preparation against gas explosion due to static electricity.

In addition, the existing house is equipped with a sprinkler, which is a fire extinguishing facility, but it is used to prevent the spread of the fire by operating after the fire rather than preventing the fire from occurring.

Korean Unexamined Patent Publication No. 1998-016039 (published May 25, 1998) discloses an automatic gas detection and emission system and a control method. The above prior art document 1 is a system having a gas leakage detection alarm, a valve breaker, and an exhaust fan, and provides a system for shutting down the operation of the boiler, shutting off the gas valve, and operating the exhaust fan at the same time that the alarm sounds after the gas is leaked have. However, when the gas leakage due to damage to the gas pipe of the large facility is not sufficiently exhausted by the exhaust fan, a considerable amount of gas is retained in the facility for a long time. Therefore, And a second explosion fire due to static electricity of the human body is built in. In addition, an exhaust fan must be additionally installed for use in an ordinary household, and in the process of driving the exhaust fan even when the exhaust fan is installed, Is still inherent.

Korean Registered Patent No. 10-1167964 (Registered on July 17, 2012, hereinafter referred to as 'Prior Art Document 2') discloses an electrostatic discharge detecting device. In the prior art document 2, the discharge module and the grounding module are provided to ground the static electricity when the contact is made so that the discharge is performed, and the electrostatic amount is numerically displayed on the outside in the discharge process, thereby reducing the electrostatic amount accumulated in the human body And a static electricity detecting and removing device is provided. However, the above-mentioned prior art document 2 can also remove static electricity accumulated when a manager touches it, so that it can not provide stability to entrants entering the site without performing a static elimination process, and is not suitable for being equipped in a general home Explosion by static electricity It can not be a fundamental solution to fire prevention.

Korean Registered Patent No. 10-0505261 (registered on Jul. 25, 2005, hereinafter referred to as 'Prior Art 3') proposed an electrostatic detection and control system in an industrial facility. The prior art document 3 includes a temperature / humidity sensor for detecting temperature and humidity in real time in an industrial facility; A potential sensor for detecting real-time static electricity of the industrial facility; Humidity, and static electricity outputted from the temperature / humidity sensor and the electric potential sensor are converted into digital data capable of being monitored and stored, and when the temperature, humidity, and static electricity are out of the predetermined temperature and humidity range, A CPU for outputting a constant control signal for removing static electricity; A static eliminator for injecting ions to remove static electricity from the industrial facility using the output signal of the CPU as an input signal and injecting water and air so as to have a constant temperature and humidity; And a communication cable connected to the CPU, the temperature / humidity sensor, and the electric potential sensor for transmitting the temperature, humidity, and static physical quantity to the CPU. In this prior art document 3, a static eliminator for removing static electricity has a high voltage generator and an electric water spray nozzle which are opposite in polarity to static electricity, but this is a method taken when static electricity is generated in a facility. That is, the prior art 3 has a difficulty in installing equipment in an ordinary residential house, and since there is no ability to prevent the generation of pre-static electricity, there is still a risk of explosion due to static electricity in a gas leakage environment.

Therefore, it is necessary to study a new type of gas explosion fire prevention system that enables urgent repair by preventing explosion of gas caused by static electricity even if a manager enters the gas leakage or vapor saturation without static electricity damping.

The installation position of the gas sensing sensor 20 may vary depending on the gas to be used. Generally, the gas sensing sensor 20 is installed on the ceiling, the wall, and the floor of the facility.

The humidity measurement sensor 40 measures the humidity in the facility and can minimize the power consumption by continuously measuring the humidity or measuring the humidity from the time when gas leakage is detected.

The water spraying device 30 is a device for spraying water at the time of gas sensing to increase the humidity of a nearby area.

In addition, water may be stored in the water chamber 33, and the moisture may include a conductive material such as metal ions, and an inlet and an outlet may be formed at one side to re-introduce or replace water .

A pump connected to the injection nozzle is installed in the shielding chamber 34 and a supply line 342 for supplying moisture stored in the moisture chamber to the pump 341 is connected. The supply line 342 is provided with an intermittent valve 343 for interrupting the flow path, and the intermittent valve is formed of a solenoid valve, and can be automatically opened and closed by a signal from the control device. In the shielding chamber 34, the gap is blocked from the outside by using a packing or a finishing material to prevent the inflow of the external gas, thereby preventing the gas explosion in the internal power supply process.

Further, the shielding chamber 34 may be positioned at the lowest space even when the case 31 is vertically elongated or elongated in the transverse direction as shown in the drawing, so that the moisture of the moisture chamber is prevented by the self- And when the pump is positioned above the water chamber 33, the inlet side of the supply line is positioned below the water chamber, so that suction can be performed by the pumping force of the pump .

The pump 341 installed in the always-on shielding chamber 34 may be a one-axis screw or a two-axis screw. When the power is supplied by the controller 50, moisture supplied from the water chamber is supplied through the injection nozzle 311 In this process, moisture is sprayed into small particles in the form of mist, so that the humidity of the surrounding area can be increased.

The power supply source 344 supplied to the pump 341 may be connected to the outside through a line to supply power to the pump 341. Alternatively, a constant capacity replaceable power supply unit may be provided in the shielding chamber 34, Each sensor can be driven.

Next, when the sensing signal is transmitted from the gas sensing sensor 20, the control device 50 operates the water spraying devices 30 and 30a to control the indoor humidity to be raised to the set humidity.

Here, the gas sensing sensor and the control device may transmit a signal by wire or wirelessly transmit the signal, and the sensing signal may include a signal sensed by a gas sensing sensor installed in an existing fire-fighting facility.

When the control device receives the gas sensing signal, it performs a water spray containing conductive material and a human body accumulated static elimination step. In the previous step, the control device having received the detection signal transmits an operation signal to the water spraying device. The spraying device having received the operation signal can open the intermittent valve to cause water spray through the sprinkler.

Next, in the process of spraying, the controller performs a humidity check step of continuously inputting information on the humidity of the room leaked from the humidity measurement sensor.

If the humidity measurement value is greater than a predetermined value in the relative humidity range of 70 to 90% in the humidity checking step, the intermittent valve of the water spraying device is shut off to stop the spraying.

If the indoor relative humidity set in the control device is set at least 65% or more, preferably 70% or more and 90% or less, the accumulated static electricity of the human body accumulated in the moisture is removed through the conductive material or conductive ion material, Spark generation can be suppressed to prevent gas explosion, excessive moisture spray can be prevented, and damage to electronic products due to moisture can be prevented.

In addition, as shown in FIG. 5, in the step of spraying water containing the conductive material and removing static electricity from the human body,

The water spraying device which receives the operation signal from the control device opens the intermittent valve of the supply line connecting the water chamber and the pump so that the water containing the conductive substance stored in the water chamber is supplied to the pump, The high pressure is transferred to the injection nozzle, and the water formed at high pressure is sprayed in the form of mist while passing through the spray nozzle, thereby rapidly increasing the humidity in the room near the spraying device, thereby removing the static accumulation of human body accumulated by the user, .
