Abstract
The utility model discloses a positive and negative pressure water seal safety system for isolating waste gas, which is used for isolating volatilized, toxic and harmful gases from the atmosphere, comprises a positive pressure water seal tank and a negative pressure water seal tank which are connected with an original liquid storage tank through an air inlet pipeline, no control valve is arranged on the pipeline, the positive pressure water seal tank is connected with an air outlet, and the negative pressure water seal tank is connected with an opening facing the sky. According to the utility model, the running and emitting problems of a material are solved, and the condition that the storage tank bears larger positive or negative pressure to cause cracking accidents can be avoided. The positive and negative pressure water seal safety system disclosed by the utility model has the characteristics of simple structure, convenience in operation, high stability and safety, and the like.
Description
Technical field
The utility model relates to a kind of seal water system, and that particularly a kind of petrochemical industry is used to isolate is volatile, the positive and negative setting-out envelope safety system between toxic and harmful and the atmosphere.
Background technique
Water sealed tank is the safety installations of isolating between poisonous, harmful, volatile gas and the atmosphere.This equipment is used to isolate in factory and contains hydrogen cloride, sulfuric acid property gas, ammonia and other facilities poisonous, harmful gas; This device structure is simple, practical; Thereby the volatilization that can effectively prevent gas reduces the pollution to environment; Ability regulating tank internal pressure balance plays an important role for the smooth running of installing simultaneously.At present the water sealed tank that uses of chemical plant is only established single channel usually, when tank inner pressure is too high or too low, with the normal operation that has a strong impact on device, and brings serious threat to safety in production.
The model utility content
The purpose of the utility model is to overcome that water sealed tank has only single channel in the existing technology, and material is prone to run and emits in the storage tank, causes storage tank to bear big plus or minus pressure and causes defective such as tank ruptured, and the positive and negative setting-out envelope of a kind of isolation waste gas safety system is provided.
The utility model adopts following technological scheme to realize above-mentioned purpose:
The positive and negative setting-out envelope of a kind of isolation waste gas safety system; Be used for being connected to isolate harmful gas with former liquid storage tank; Comprise malleation water sealed tank and negative pressure water sealed tank, two water sealed tanks are communicated with former liquid storage tank through admission line, do not have control valve on this pipeline; Be connected with an air outlet on the malleation water sealed tank, be connected with one on the negative pressure water sealed tank eating dishes without rice or wine.
Above-mentioned admission line stretches under the malleation water seal tank level, and admission line is connected with the contact of negative pressure water sealed tank.
Above-mentioned malleation water sealed tank also is connected a water intake and a flow-off respectively with the negative pressure water sealed tank, and promptly said malleation water sealed tank all is connected water intake and flow-off with the negative pressure water sealed tank.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model adopts parallelly connected positive and negative pressure water sealed tank to form the seal water system with safety guarantee, makes device not receive the influence of production operation;
(2) seal water system of the utility model does not need operated valve, can guarantee the continuity and the Security of whole device automatically, and uses and stablize, and is easy to a control jar internal pressure balance;
(3) seal water system of the utility model is formed flexible, simple; And invest little; The race that not only efficiently solves material is emitted, and can prevent that again storage tank from bearing bigger plus or minus pressure and causing break accident, has simple in structure, easy to operate, safe characteristics.
Description of drawings
Fig. 1: isolate the positive and negative setting-out envelope of waste gas safety system structural drawing.
Embodiment
Be that example is done further elaboration to the utility model with the common salt acid storage tank seal water system in chemical plant below.
As shown in Figure 1, the drain of hydrochloric acid tank 1 is connected with admission line 2, and malleation water sealed tank 3 is in parallel installed with on admission line 2 with negative pressure water sealed tank 4.Malleation water seal malleation design pressure is the 50mm water column: during the hydrochloric acid tank charging, liquid level rises, and pressure of storage tank increases; Acid gas can be through emerging to eating dishes without rice or wine; When pressure surpassed the 50mm water column, the waste gas after being absorbed will be run out of from the air outlet 5 of malleation water seal 3, prevents to cause the tank ruptured accident.Malleation water sealed tank and negative pressure water sealed tank all are provided with water intake 7 and are used in jar, adding water, flow-off 8 is set can flows out from flow-off after the water surface rises to preset height guaranteeing, make between liquid level top and the tank deck wall and leave certain space.Negative pressure water seal negative pressure design pressure is the 10mm water column: during hydrochloric acid tank 1 discharging; Liquid level descends, and pressure of storage tank reduces, when basin degree of vacuum surpasses the 10mm water column; Air will prevent that basin from bearing bigger negative pressure and causing break accident from 6 the getting into eating dishes without rice or wine of negative pressure water seal 4.
Claims (3)
1. isolate the positive and negative setting-out envelope of waste gas safety system for one kind; Be used for being connected to isolate harmful gas with former liquid storage tank; It is characterized in that comprising malleation water sealed tank and negative pressure water sealed tank; Two water sealed tanks are communicated with former liquid storage tank through admission line, are connected with the air outlet on the malleation water sealed tank, are connected with eating dishes without rice or wine on the negative pressure water sealed tank.
2. positive and negative setting-out envelope safety system according to claim 1 is characterized in that said admission line extends to below the malleation water seal tank level, and admission line is connected with the contact of negative pressure water sealed tank.
3. positive and negative setting-out envelope safety system according to claim 1 and 2 is characterized in that said malleation water sealed tank all is connected water intake and flow-off with the negative pressure water sealed tank.
