Abstract
An air-permeable flame-inhibiting antiexplosion unit for the ordinary-pressure storage tank of liquid chemical is composed of storage tank, an air-permeable pipe fixed to the top flange of storage tank, a sealing ring between storage tank and air-permeable pipe, a protecting net in said air-permeable pipe, and the flame-inhibiting antiexplosion material HAN filled in said net.
Description
Technical field
What the present invention relates to is a kind of ventilation safety anti-explosive device of atmospheric storage tank, and it is a device of guaranteeing liquid dangerization product safety in the atmospheric storage tank.
Background technology
Store inflammable, explosive liquid state dangerization product in the atmospheric storage tank, as gasoline, diesel oil etc.Usually all will adorn breathing valve at the top of storage tank, breathing valve is communicated with the breather pipe in the storage tank.It is that regulating tank internal pressure and ambient atmosphere keep balance that the breathing valve purpose is installed, and reduces the medium volatilization in the storage tank simultaneously.But; when when in storage tank, injecting the medium of liquid dangerization product or during the rising of the ambient temperature in the storage tank external world; pressure, temperature in the corresponding storage tank also increase; order about the breathing valve opening; a large amount of miscellaneous gass of liquid dangerization product medium and air are breathed out through breathing valve; burning just takes place and also sets off an explosion as running into naked light, static, thunderbolt etc. in this moment easily.Simultaneously, medium and Air mixing gas are drained in the atmosphere in a large number, cause aerial contamination.Therefore, the breathing valve that install at the atmospheric storage tank top, and fail thoroughly to solve storage tank interior liquid state dangerization product safety and problem of environmental pollution.
The content of invention
The ventilation fire and explosion resistant device that the purpose of this invention is to provide a kind of atmospheric storage tank thoroughly solves the safety of liquid dangerization product in the atmospheric storage tank, the volatilization of minimizing medium and the pollution of environment.
A kind of ventilation fire and explosion resistant device of atmospheric storage tank includes atmospheric storage tank, it is characterized in that being provided with in storage tank breather pipe, and the flange of breather pipe is provided with seal ring by on the flange that is bolted to the atmospheric storage tank top between atmospheric storage tank and the breather pipe.In breather pipe, be provided with grille guard, filled up HAN flame-proof explosion-proof material in the grille guard.
Grille guard is matching with breather pipe inwall type shape of being surrounded by stainless steel wire or galvanized iron wire, and the bottom is connected with bearing net.
Breather pipe adopts the stainless steel sheet of 1～2 millimeters thick to be stamped to form.
Top at breather pipe is connected with rainproof cover by support.
HAN flame-proof explosion-proof material is netted or spherical special alloy material, and above-mentioned alloy material is corrosion-resistant steel or aluminum alloy etc.
Advantage of the present invention:
1, replace breathing valve, a jar internal pressure is communicated with and keeps balance with ambient atmosphere, remain normal pressure in the storage tank.
2, stop a large amount of gases of interior dangerization product medium of storage tank and air-blending when running into naked light, thunderbolt, can not blast.
3, suppress the medium volatilization, reduce a jar interior relative permitivity.
4, eliminate static.
5, simple in structure, easy for installation, be easy to safeguard.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Wherein:
1. atmospheric storage tank, 2. breather pipe, 3. grille guard, 4.HAN flame-proof explosion-proof material, 5. seal ring, 6. rainproof cover, 7. bolt, 8. support.
The embodiment explanation
In breather pipe 2, be provided with grille guard 3, in grille guard 3, filled up HAN flame-proof explosion-proof material 4.Grille guard 3 is that inwall type shape that surrounded by stainless steel wire or galvanized iron wire and breather pipe 2 matches, and the bottom is connected with bearing net.The protecting wire net purpose of setting up defences is that prevent HAN flame-proof explosion-proof material 4 broken reams in the storage tank, also can clean HAN flame-proof explosion-proof material easily simultaneously.
This ventilation fire and explosion resistant device is the opened type structure, and atmospheric storage tank is communicated with ambient atmosphere, keeps the pressure in the storage tank to be in conventional pressure state all the time.
The HAN flame-proof explosion-proof materials 4 that are provided with in the breather pipe 2 are for patented product-its application number of subordinate unit of our company invention is 92102437.1, name is called " explosion-suppressing material that is used for explosives, inflammable items " (authorizing).The mechanism of HAN flame-proof explosion-proof material 4 is according to heat transfer theory and forms the pacing factor of burning, exploding, the flame-proof explosion-proof product of researching and developing.In the reservoir vessel of liquid state dangerization product, place HAN flame-proof explosion-proof material, can stop the burning of medium and the generation of blast.The structure of HAN flame-proof explosion-proof material is a kind of honeycomb structure of high hole, it can stop the bamboo telegraph of flame and the abrupt release of energy, utilize the surface effect of its material to absorb lot of energy, destroyed the explosion condition of combustion medium, thereby stop the burning of medium and the generation of blast.
When in atmospheric storage tank 1, injecting liquid dangerization product medium or during the ambient temperature rising in storage tank 1 external world; pressure, temperature in the corresponding storage tank also increase, and liquid state dangerization product medium and a large amount of gases of Air mixing in the storage tank at first enter in the honeycomb structure of HAN flame-proof explosion-proof material 4 by breather pipe 2.Because the characteristic of the fire-retardant quick-fried material 4 of HAN has stoped the bamboo telegraph of flame and the abrupt release of energy, the surface of material has absorbed lot of energy, destroyed the combustion of mixed gas condition, stoped the generation of burning and blast as running into unforeseen circumstancess such as naked light, thunderbolt this moment.HAN flame-proof explosion-proof material can also suppress the medium volatilization, reduces the effect of relative permitivity.
Because HAN flame-proof explosion-proof material can suppress the volatilization of medium, reduce the friction of volatile medium and air greatly, and HAN flame-proof explosion-proof material is to be made by the special alloy material, this alloy material comprises by corrosion-resistant steel, aluminum alloys etc., it has good electric conductivity, can eliminate static.
This ventilation fire and explosion resistant device can be transformed original equipment easily, removes breathing valve, in former breather pipe grille guard is set, and fills up HAN flame-proof explosion-proof material in grille guard, can realize above-mentioned purpose.It is simple in structure, and is easy for installation, is easy to safeguard.
