Description
Technical field
The utility model belongs to chemical equipment technical field, is related to a kind of chemical industry storage tank liquid breather valve.
Background technology
For storing liquid industrial chemicals and the atmospheric storage tank of product, usually at the top of it is mating be provided with desorption tube or
The devices such as the mechanical breather valve of spring retainer, for balancing storage tank inner and outer air pressure, it is ensured that safety.But in use exist with
Lower defect：1, desorption tube is to empty direct emission tail gas pollution environment, corrosion peripheral equipment, and is unfavorable for the body and mind of operating personnel
Health；2, mechanical breather valve is easy to be blocked by gas attack or saline crystallization, the function of disequilibrium air pressure.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model to provide a kind of chemical industry storage tank liquid breather valve, its profit
Liquid chemical storage tank air pressure balance can be realized with fluid-tight principle, have absorption concurrently or wash the function that storage tank diffuses tail gas.
Technical solution adopted by the utility model to solve its technical problems is：A kind of chemical industry storage tank liquid breather valve, packet
The underfill for including sealing has a babinet of filling liquid, in babinet by barrier partitions at left and right two parts, wherein left-hand component
Top is provided with the diffusion mouth being connected with the external world, and bottom is equipped with the evacuation port with valve, benefit is offered on the left side wall of babinet
Liquid mouth；Right-hand component is provided with the air inlet surrounded by bottom plate, and air inlet open height is higher than filling liquid liquid level.
The babinet is made of the metal material of acid-alkali-corrosive-resisting.
The diffusion mouth is for connecting installation desorption tube, directly to sky.
The evacuation port is used to empty the filling liquid in babinet.
The air inlet is connected with diffusion mouth at the top of fluid chemical storage tank.
Air pressure balance between the left-hand component and right-hand component is mainly the difference in height h variation realizations by filling liquid
, that is, work as P1More than or less than P0When with the sum of h, the difference in height h of filling liquid is raised and lowered automatically, until P1Equal to P0The sum of with h
When, chemical industry storage tank inside and outside air pressure balance is just realized, has achieved the purpose that storage tank safety and environment protection emission.
The filling liquid select boiling point is high, saturated vapour pressure is small, good fluidity, be not easy to solidify, not with liquid in chemical industry storage tank
Chemical reaction and substance that is pollution-free, being easy to get, such as industrial water occur for body；Filling liquid can also select absorption or washing
Chemical industry storage tank diffuses the substance of tail gas, and if acid tail gas is filled using sodium hydroxide solution, alkaline tail gas is filled out using sulfuric acid solution
It fills.
The utility model has the beneficial effects that：Liquid breather valve can effectively prevent storage tank tail gas it is direct idle discharge is put,
The shortcomings that absorbing or washing storage tank diffuse tail gas, and mechanical breather valve can be overcome perishable or blocked.The present invention not only ensures
Chemical industry storage tank safety, and improve execute-in-place environment, it is conducive to environmental protection and health；It only need to be to being filled out in breather valve when daily maintenance
Filling liquid supplement or replace in right amount, you can the normal function for the valve that ensures respiration.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model side view；
Fig. 3 is the utility model vertical view.
In figure：1, diffusion mouth；2, baffle；3, babinet；4, bottom plate；5, air inlet；6, fluid infusion；7, evacuation port.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Fig. 1~Fig. 3, a kind of chemical industry storage tank liquid breather valve, including the underfill of sealing have the babinet of filling liquid
3, babinet 3 is interior to be separated into left and right two parts by baffle 2, is wherein provided at the top of left-hand component and is diffused with what the external world was connected
Mouth 1, bottom are equipped with the evacuation port 7 with valve, fluid infusion 6 are offered on the left side wall of babinet 3；Right-hand component is provided with by bottom plate
4 air inlets 5 surrounded, 5 height of air inlet are higher than filling liquid liquid level.
The babinet 3 is made of the metal material of acid-alkali-corrosive-resisting.
The diffusion mouth 1 is for connecting installation desorption tube, directly to sky.
The evacuation port 7 is used to empty the filling liquid in babinet 3.
The air inlet 5 is connected with diffusion mouth 1 at the top of fluid chemical storage tank.
Air pressure balance between the left-hand component and right-hand component is mainly the difference in height h variation realizations by filling liquid
, that is, work as P1More than or less than P0When with the sum of h, the difference in height h of filling liquid is raised and lowered automatically, until P1Equal to P0The sum of with h
When, chemical industry storage tank inside and outside air pressure balance is just realized, has achieved the purpose that storage tank safety and environment protection emission.
The filling liquid select boiling point is high, saturated vapour pressure is small, good fluidity, be not easy to solidify, not with liquid in chemical industry storage tank
Chemical reaction and substance that is pollution-free, being easy to get, such as industrial water occur for body；Filling liquid can also select absorption or washing
Chemical industry storage tank diffuses the substance of tail gas, and if acid tail gas is filled using sodium hydroxide solution, alkaline tail gas is filled out using sulfuric acid solution
It fills.
Liquid breather valve can effectively prevent the direct of storage tank tail gas and storage tank be put, absorbed or washed to idle discharge diffuse tail gas,
The shortcomings that capable of overcoming mechanical breather valve perishable again or blocking.The present invention not only ensures chemical industry storage tank safety, and improves
Execute-in-place environment is conducive to environmental protection and health；Filling liquid in breather valve 8 need to only be supplemented or be set in right amount when daily maintenance
It changes, you can the normal function for the valve that ensures respiration.
