The safety protection device of a kind of sealed pipeline of volatile toxic liquid of the present invention; Its working principle is: with the rising of fluid temperature in the airtight pipeline; When causing the interior partially liq vaporization of pipeline that pipeline inner pressure is raise; For the leakage that prevents toxic gas to the waste of liquid itself and the pollution and the too high potential safety hazard of bringing of pipeline inner pressure of environment; From the recycle and reuse of liquid and the aspect that effectively discharges airtight pipeline inner pressure, when airtight pipeline inner pressure during with the liquid level rising, the method through condensation makes that toxic gas is converted into liquid state again in the pipeline; Both made pipeline inner pressure obtain discharging and made the sealed tube rood, and made the interior liquid of airtight pipeline obtain reclaiming again to protection.
Described apparatus main body is the funnel form container; Large cylinder, the middle part that it has an end cap by top is that little cylinder three parts that big osculum and bottom have a device fastening flange are welded, so that the safety protection device of the airtight pipeline of whole toxic liquid is connected with the airtight pipeline that has the same size flange.For convenient airtight pipeline and the respective line thereof of giving adds circulating liquid; Design one in the center portion of apparatus main body large cylinder part upper end cap and had externally threaded shoulder hole, be connected the sealing of implement device through outside thread with the sealing cover that is processed with same sized internal thread; Upper end cap at apparatus main body also is equipped with reduction valve, electronics coolship, radiator, fan.Be processed with an interior threaded hole at upper end cap, be used to install reduction valve; The electronics coolship is cuboid parts, owing to do not allow punching above it, designed can be to electronics coolship, radiator, the fixing integrated fixing device of fan for this reason; Fixing device is connected with the upper end cap of apparatus main body through 4 apertures on it, for the leakage of anti-fluid, avoids the upper end cap perforate at apparatus main body as far as possible; Corresponding site at upper end cap has welded 4 screw rods; When mounted, make screw rod pass 4 holes of fixing device, use nut check then; In order further to improve efficient of the present invention and reliability, designed recycling and processing device, be connected with the outlet of reduction valve through corresponding pipeline; Fill certain reagent in this device inside, top seals with the recycling and processing device sealing cover.When running into that special circumstances make that airtight loine pressure is excessive and when reduction valve is opened; Toxic gas reacts through the pipeline entering recycling and processing device preprepared reagent inner with it that connects recycling and processing device and reduction valve relief opening in the airtight pipeline; Generation does not have the product of harm to human body and environment, thereby has further increased Security.In order to improve the efficient of electronics coolship, the loam cake of apparatus main body requires level and smooth as far as possible.
3, advantage and effect: the beneficial effect that the present invention had is:
(1) can realize release reliably, thereby it is played a protective role airtight pipeline inner pressure.
(2) because the part that the volatility toxic liquid is vaporized that the present invention adopts is carried out the method that atmosphere was used rather than directly entered to cool cycles; Effectively realized the recovery of liquid in the airtight pipeline; Both realized recycling of liquid, avoided again to the pollution of environment with to the injury of the person.
(3) method for security protection of sealed pipeline of volatile toxic liquid provided by the invention and device; Be not only applicable to that liquid is the airtight pipeline of some common liqs such as water in the sealed tube road; Be particularly useful for system and equipment that airtight pipeline liquid is poisonous, inflammable, the explosive liquid of volatility; Widened this class I liquid I in the Industrial Application scope, realized that (like normal propyl alcohol, fusing point is-126.2 ℃ with a kind of liquid; 101.3KPa the time boiling point be 97.2 ℃) replaced before temperature range by two kinds of liquid (like water, ethanol); Simplified the structure of airtight pipeline and avoided equipment repetition structurally, reduced design of plant and operating cost, had more widely and use.
