Description

The invention relates to a device for producing distilled water used in medical, pharmaceutical, biotechnological, electronic, chemical and other industries.

Known apparatus for producing distilled water:

1. Patent RU No. 2008266 C1 "Gorlov Distiller";

2. Patent RU No. 2090511 C1 "Distiller";

3. Patent RU No. 2106175 C1 "Distiller";

4. Patent RU No. 2217674 C2 "Collapsible capacitor akvadistillyator."

Closest to the claimed technical solution is Patent RU No. 2048155 C1 “Continuous Distiller”.

The disadvantage of this device is the design complexity and inconvenience of operation.

The aim of the invention is to increase the technological capabilities of an akvadistillyator, increase the reliability of operation, ease of operation and maintenance.

This goal is achieved by the fact that in the condensation chamber of the akvadistillyator with an automatic protection system there is a degassing cap made in the form of a cylindrical shell with a cover, while there are radial degassing grooves in the lower part of the shell, an automatic control system is provided to shut off the supply of initial water to the aqua distiller overflow of the source water through the equalizer, shutting off the supply of source water to the aqua distiller when supplying the source water of inadequate quality or above ii permissible level of contamination of water in the evaporation chamber, caused by the distillation process, the adjustment amount of initial water supply in dependence on the desired temperature of the resulting distillate.

In order to increase the convenience of operation, the design provides a detachable connection of the evaporator with the condenser, which allows removing scale and water stone from the evaporation chamber of the aqua distiller.

The essence of the claimed invention is illustrated by drawings, where in FIG. 1 shows a General view of an akvadistillyator; in FIG. 2 shows an aqua distiller in a detachable state.

The water distiller with an automatic protection system (Fig. 1) contains an evaporator 1, a condenser 2, a separator 3, a control unit 4. The evaporator 1 consists of an evaporation chamber 5 (Fig. 2), in which an electric heater 6, equalizer 7, and an evaporator 12 pollution sensor are installed , thermal insulation 13 and the evaporator casing 14. leveling device 8, overflow sensor 9, overflow pipe 10 and drain valve 11 are installed in equalizer 7. Condenser 2 consists of a condensation chamber 15 (Fig. 2), a pipe condenser 19, a degassing cap 20, a cover condensation chambers 23, con camera chamber of condensation 24 and the cover of the casing 25. The condensation chamber 15 consists of a shell of the condensation chamber 16 and a distillate collecting tray 17 with a distillate collecting nozzle 18. The degassing cap 20 consists of a cover 21 and a shell 22. A valve 26 is installed at the inlet to the pipe condenser 19, at the outlet an adjustable valve 27 and a temperature controller sensor 28 are installed. A separator 3 is attached to the bottom of the condenser 2.

Aquadistillator with automatic protection system works as follows. The source water is supplied to a valve 26 installed in the pipe condenser 19, from the output of which is supplied to equalizer 7, while an adjustable valve 27 and a temperature controller sensor 28 are installed at the output of the pipe condenser 19. Next, the water enters the evaporation chamber 5 with an electric heating element installed in it 6. When the evaporation chamber is filled to the operating level, the level 8 sensor installed in equalizer 7 sends a signal to the control unit, and the heater is turned on 6. Then, during operation, the water level in 5 Amer evaporation maintained automatically via the overflow pipe 10. The water is heated, boils and is converted into steam. At the exit from the evaporation chamber 5 steam passes through a separator 3, freeing itself from water droplets. Then the steam enters the condensation chamber 15, where it condenses on the pipe condenser 19 and enters the distillate collection tray 17. The condensed distillate leaves the aqua distiller through the distillate collection nozzle 18.

The temperature of the distillate is interconnected with the temperature of the water leaving the pipe condenser, which depends on its quantity and its inlet temperature. To obtain a distillate with the required temperature at the outlet of the pipe condenser 19, a temperature controller sensor 28 is installed that transmits data on the water temperature at the outlet of the pipe condenser 19 to the control unit 4. If the set temperature of the distillate does not match, the control unit 4 sends a signal to the adjustable valve 27, which changes the passage cross-section, regulates the amount of water passing through it, which in turn allows you to adjust the temperature of the resulting distillate.

In the condensation chamber 15, on the collection tray of the distillate 17, a degassing cap 20 is installed that covers the pipe condenser 19. The degassing cap 20 is made in the form of a cylindrical shell 22 with an upper cover 21, while in the lower part of the shell 22 there are degassing grooves through which the process distillation gases leave the condensation zone and through the holes in the cover 23 of the condensation chamber 20 go beyond the limits of the condenser. Removing gases from the condensation zone improves the quality of the resulting distillate without sacrificing performance.

If the source water of inadequate quality is supplied to the akvadistillyator or the permissible level of water pollution in the evaporation chamber caused by the distillation process is exceeded, the water will foam when boiling, reducing the quality of the resulting distillate. To exclude the receipt of poor quality distillate between the collection tray of the distillate 17 and the separator 3, the evaporator 12 pollution sensor is installed. When the evaporator 12 pollution sensor is activated, the control unit 4 turns off the electric heater 6 and sends a signal to the valve 26 to stop the supply of source water. The resuming operation of the water distiller is carried out after cleaning the evaporation chamber and supplying the source water of the proper quality.

For visual inspection and cleaning of the evaporation chamber, the aqua distiller design is made of two parts, the lower part consists of an evaporator 1, the upper part consists of a condenser 2 and a separator 3.

When the supply of water is stopped in the evaporation chamber, an excess of steam is formed, which displaces water from the evaporation chamber 5 to equalizer 7. The water level in the evaporation chamber decreases below the top of the electric heater 6, and in the equalizer 7, the water level rises. The level sensor 8 continues to signal that the required water level is in the evaporation chamber. To prevent the failure of the electric heater 6, the overflow sensor 9 installed in the equalizer 7 sends a signal to the control unit 4, which turns off the electric heater 6. When an excess amount of the source water is supplied to the water distiller, the water level in the evaporation chamber 5 and equalizer 7 rises. To prevent overflow of water through the upper edge of the equalizer 7, the overflow sensor 9 sends a signal to the control unit 4, which turns off the electric heater 6 and sends a signal to the valve 26, to stop the supply of source water.

The claimed invention can be used in various industries.

Using the proposed aqua distiller with an automatic protection system allows, in comparison with the prototype, to obtain the following technical and economic advantages:

- reduce energy costs due to the automatic control system of akvadistillyator;

- to improve the convenience of operation and maintenance, due to the detachable design of the aqua distiller;

- improve the quality of the obtained distillate using a degassing cap;

- eliminate the decline in the quality of the obtained distillate due to the sensor of pollution of the evaporator;

- eliminate water overflow from equalizer when supplying an excess amount of source water using an overflow sensor;

- provide protection against failure of the electric heater using an overflow sensor;

- maintaining the required temperature of the obtained distillate using a temperature controller sensor and an adjustable valve.
