Abstract

It the utility model is related to a kind of recovery system for the steum separating device liquefied gas tank safety dumping that liquefies.Mainly solve the problems, such as that existing apparatus occurs losing a large amount of liquefied gas tanks during fluctuation over-temp and over-pressure safety valve jumping up and pollutes environment.It is characterized in that:The return tank(3)Top outflow pipeline is connected to torch surge tank(4)Tank deck;Torch surge tank(4)Tank deck outflow pipeline connects closed liquefied gas tank pressure recovery tank(5);Closed liquefied gas tank pressure recovery tank(5)Tank deck pipeline removes torch, closed liquefied gas tank pressure recovery tank(5)Tank bottom pipeline is connected to return tank(2)Tank deck;Torch surge tank(4)Tank bottom pipeline is connected to liquefied gas tower(1)Bottom of towe.The recovery system of the liquefaction steum separating device liquefied gas tank safety dumping, can reclaim a large amount of liquefied gas tanks, free from environmental pollution.

Description

The recovery system of liquefaction steum separating device liquefied gas tank safety dumping
Technical field
It the utility model is related to a kind of liquefaction steam reclamation system, particularly a kind of liquefied gas tank point in technical field of petrochemical industry From the recovery system of device liquefied gas tank safety dumping.
Background technology
The liquefied gas tank for largely adulterating various solvents be present in chemical industry liquefaction steum separating device, when there is fluctuation, surpass Take-off phenomenon occurs for warm overpressure facility safety valve.When over-temp and over-pressure safety valve jumping up occurs for device, substantial amounts of liquefied gas tank decompression Enter torch after heating into torch surge tank to burn up, have lost a large amount of liquefied gas tanks, while the burning environmental pollution of liquefied gas tank It is very serious.
The content of the invention
Technical problem to be solved in the utility model is to overcome existing apparatus present in background technology production ripple occur The problem of losing a large amount of liquefied gas tanks during dynamic over-temp and over-pressure safety valve jumping up and pollute environment, and a kind of liquefaction steum separating device is provided The recovery system of middle liquefied gas tank safety dumping, the recovery system of the liquefaction steum separating device liquefied gas tank safety dumping, can be reclaimed A large amount of liquefied gas tanks, it is free from environmental pollution.
The invention for solving the technical problem can reach by following technical solution:The liquefaction steum separating device liquefied gas tank is pacified The recovery system discharged entirely, including liquefied gas tower, liquefied gas column overhead connection return tank, the return tank top outflow pipeline connect It is connected to torch surge tank tank deck;Torch surge tank tank deck outflow pipeline connection liquefied gas tank recovery seal-off pressure tank;Liquefied gas tank reclaims Seal-off pressure tank tank deck pipeline removes torch, and liquefied gas tank recovery seal-off pressure tank tank bottom pipeline is connected to return tank tank deck;Torch delays Rush the bottom of towe that tank tank bottom pipeline is connected to liquefied gas tower.
The utility model can have the advantages that compared with above-mentioned background technology:The liquefaction steum separating device liquefies The recovery system of vapour safety dumping, when over-temp and over-pressure safety valve jumping up occurs for the steum separating device that liquefies, substantial amounts of liquefied gas tank subtracts It is pressed into the surge tank with heating coil, liquefied gas restoring pressurized tank is discharged into by check valve after heating, when liquefied gas tank exists When reaching a certain amount of in liquefied gas tank recovery seal-off pressure tank, tank pressure rises, and liquefied gas tank becomes liquid, pumped is reclaimed by liquefied gas tank Send return tank of top of the tower back to so that a large amount of liquefied gas tanks are reclaimed, and prevent from polluting environment.
Brief description of the drawings
Accompanying drawing 1 is system flow chart of the present utility model.
In figure:1 liquefied gas tower;2nd, cooler;3rd, return tank;4th, torch surge tank;5th, closed liquefied gas tank pressure recovery Tank;6th, recovery pump.
Embodiment:
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, the recovery system of the liquefaction steum separating device liquefied gas tank safety dumping, including liquefied gas tower 1, liquid Change the overhead line of gas tower 1 and the tank deck of return tank 3 is connected to by cooler 2;The tank bottom pipeline of return tank 3 is back to liquefied gas tower 1;Backflow Outflow pipeline in the top of tank 3 is connected to the tank deck of torch surge tank 4;The tank deck of torch surge tank 4 outflow pipeline connects closed liquefied gas tank and returned Receive pressurized tank 5;The closed tank deck pipeline of liquefied gas tank pressure recovery tank 5 removes torch, and the closed tank bottom pipeline of liquefied gas tank pressure recovery tank 5 connects It is connected to the tank deck of return tank 3;The tank bottom pipeline of torch surge tank 4 is connected to the bottom of towe of liquefied gas tower 1;The tank deck of torch surge tank 4 Outflow pipeline is connected to check valve;Safety valve is connected on the top of return tank 3 outflow pipeline;The closed tank bottom of liquefied gas tank pressure recovery tank 5 Recovery pump 6 is connected with pipeline.
When over-temp and over-pressure safety valve jumping up occurs for the steum separating device that liquefies, substantial amounts of liquefied gas tank decompression enters band heating In the torch surge tank 4 of coil pipe, volume is discharged into as 10 cubic metres by check valve after heating, operating pressure is the close of 1.0Mpa Liquefied gas tank pressure recovery tank is closed, after liquefied gas tank enters in closed liquefied gas tank pressure recovery tank, when tank pressure rises to 0.1Mpa, liquid Change vapour and become liquid, return tank of top of the tower 3 is sent back to by liquefied gas tank recovery pumped so that a large amount of liquefied gas tanks are reclaimed, and prevent dirt Contaminate environment.
Blue stone Co., Ltd implements this practicality to the separator liquefied gas tank safety dumping recovery process of carbon four in grand celebration It is new.After the device goes into operation, application effect is very good, has reached the standard of device dangerous contamination material zero-emission, plant running Normally utility model effect is reached.
