Abstract
A kind of positive/negative-pressure superpressure pressure relief device in pot type sulphuric acid concentration equipment is related to a kind of device for applying pressure release during Waste Sulfuric Acid cooking-pot type concentrates distillation purifying.Mainly somewhere leakage can be caused water to be caused to be inhaled into negative-pressure pipeline when negative pressure is excessive in system to solve the problem of to generate positive pressure in pot type sulphuric acid concentration system at present to design.PTFE Lined Pipelines are connected on the negative-pressure pipeline of Distallation systm, the lower end of PTFE Lined Pipelines is inserted into PTFE lined can bodies, the top of PTFE lining tank bodies is equipped with water supply pipe, the lower part of PTFE lining tank bodies is equipped with drainpipe, water supply pipe is equipped with cutting ball valve, and drainpipe is equipped with cutting ball valve and visor, and the top of PTFE lining tank bodies is additionally provided with balance pipe, the bottom of PTFE lining tank bodies is equipped with discharging tube, and discharging tube is equipped with ball valve.Advantage is when the positive pressure or excessive negative pressure that Distallation systm is unstable and generates, it can be achieved that releasing pressure automatically.
Description
Technical field：
The utility model is related to a kind of devices for applying pressure release during Waste Sulfuric Acid cooking-pot type concentrates distillation purifying.
Background technology：
In pot type sulphuric acid concentration system, using micro-negative pressure operation, when generating positive pressure when Distallation systm is unstable, it can make
At somewhere in system or many places connection leakage, uncontrollable discharge is caused, super high pressure accident can be caused when pressure is excessive, need to stop inspection
It repaiies, and is great security risk.Can cause to arrange material sulfuric acid outside system when negative pressure is excessive and hang, can not overflow, or even meeting
Cause water to be inhaled into negative-pressure pipeline, into system, causes the accident.
Invention content：
The technical problem to be solved by the utility model is to provide it is a kind of when Distallation systm is unstable and generate positive pressure or
, it can be achieved that positive/negative-pressure superpressure pressure relief device in self-relieving pot type sulphuric acid concentration equipment when person's negative pressure is excessive.
What above-mentioned purpose was realized in：PTFE Lined Pipelines, PTFE linings are connected on the negative-pressure pipeline of Distallation systm
The lower end of pipeline is inserted into PTFE lined can bodies, and the top of PTFE lining tank bodies is equipped with water supply pipe, under PTFE lining tank bodies
Portion be equipped with drainpipe, water supply pipe be equipped with cutting ball valve, drainpipe be equipped with cutting ball valve and visor, PTFE lining tank bodies it is upper
Portion is additionally provided with balance pipe, and the bottom of PTFE lining tank bodies is equipped with discharging tube, and discharging tube is equipped with ball valve.The other end of balance pipe with
Waste gas absorbing system connects.
Operation principle：
1. PTFE Lined Pipelines to be inserted into the appropriate depth of PTFE lining tank bodies straight down, served as a contrast to PTFE by water supply pipe
In moisturizing in tank body, continuously have few water outflow in visor, realize the water seal to insertion tube.
2. when system pressure is excessive, sour gas is entered by PTFE Lined Pipelines in PTFE lined can bodies, is passed through
Water seal is discharged from balance pipe, enters waste gas absorbing system.
3. when system negative pressure is excessive, when the head of liquid generated more than PTFE Lined Pipeline double altitudes water, PTFE linings
In water in tank body out of PTFE Lined Pipelines sucking Distallation systm negative-pressure pipeline, make PTFE lined cans hydropenia and gas leakage,
It is entered in system from balance pipe sucking gas, until system negative pressure is not more than the pressure that water seal depth generates, system is automatic
It is normal to restore pressure.
4. by water supply pipe continuous moisturizing into PTFE lined can bodies, there is few water outflow in visor always, realize
Water seal to PTFE Lined Pipelines, while a small amount of hot dilute sulfuric acid condensed out in Distallation systm negative-pressure pipeline is diluted, and rise dilute
Effect of sulfuric acid is released, in order to select material.
The utility model has the advantages that：The positive pressure that is generated when Distallation systm is unstable or when excessive negative pressure, it can be achieved that
Releasing pressure automatically solves the problems, such as that positive pressure is exploded, negative pressure is excessive and hangs material, ensure that production safety.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model, and 10 be Distallation systm in figure, and 11 be waste gas absorbing system.
Specific implementation mode：
Referring to Fig.1, PTFE Lined Pipelines 2 are connected on the negative-pressure pipeline of Distallation systm 1, the lower end of PTFE Lined Pipelines is inserted
Enter into PTFE linings tank body 3, the top of PTFE lining tank bodies is equipped with water supply pipe 4, and the lower part of PTFE lining tank bodies is equipped with draining
Pipe 5, water supply pipe are equipped with cutting ball valve 6, and drainpipe is equipped with cutting ball valve and visor 7, and the top of PTFE lining tank bodies is also set
There are balance pipe 8, the bottom of PTFE lining tank bodies to be equipped with discharging tube 9, discharging tube is equipped with ball valve, the other end and exhaust gas of balance pipe
Absorption system connects.
