Description
Technical field
The present invention relates to a kind of backpurge systems, more particularly, to a kind of recoil for chemical industry for making chlorine and alkali salt refining ceramic membrane
System belongs to chemical industry for making chlorine and alkali design of technological arrangement manufacturing technology field.
Background technique
Chemical industry for making chlorine and alkali primary refined brine process, due to ceramic membrane filter technique have process it is short, without preprocessor, filtering
The advantages that brine quality is excellent and transformation is convenient, has gradually obtained generally using in chlor-alkali industry.
It, need to be to film table because the pollution of film surface will lead to flux decline after ceramic membrane saline water filter runs a period of time
Face periodically carries out physics recoil and chemical cleaning.Physics recoil is exactly refined brine after the tank pressurized with compressed air that recoils, and is passed through
Backwash liquid is pressed into film by automatic quck-opening valve, carries out back flush to film surface.
Pressure and pressure difference, too low kickback pressure when repercussion effect depends on recoil make the pressure difference between shell side and tube side
It is smaller, the effect of recoil film surface pollution is not achieved；And excessively high kickback pressure may damage membrane component, sealing ring etc..Recoil
The pressure of liquid is determined by the air pressure of air cushion tank.
In factory's actual motion, use point more, inconsistent using pressure due to compressed air, common compression air is equal
It is to be provided according to maximum working (operation) pressure (MWP), this pressure is higher than the kickback pressure of ceramic membrane, the wink especially opened in quck-opening valve
Between, ceramic-film tube easy to damage, and using direct-operated regulator under source air pressure fluctuation, effect is poor.
Summary of the invention
The technical problems to be solved by the present invention are: provide it is a kind of can or fluctuation larger situation high in source air pressure
Under, still ensure that the stable backpurge system for chemical industry for making chlorine and alkali salt refining ceramic membrane of pressure when ceramic membrane recoil.
Used technical solution is to solve above-mentioned technical problem: a kind of for chemical industry for making chlorine and alkali salt refining ceramic membrane
Backpurge system, including air cushion tank, the backpurge system further include tank stabipack, and the air in the course of work is slow
The internal pressure for rushing tank keeps stablizing by the tank stabipack.
Further, the tank stabipack includes pressure transmitter, the pressure transmitter is arranged in described
On the upper cover of air cushion tank.
The preferred mode of the above solution is that the tank stabipack further includes air inlet adjustment valve, the air inlet adjustment
Valve is mounted on the gas input of the air cushion tank.
Further, the air inlet adjustment valve further includes intelligent pressure adjustment module, the pole of the air inlet adjustment valve
Limits pressure close value is limited by the intelligent pressure adjustment module.
The preferred mode of the above solution is that back flushing gas delivery pipe is provided on the air cushion tank, described
It is provided in back flushing gas delivery pipe from force regulating valve.
Further, the tank stabipack further includes decompression control valve, it is arranged in the end of the pressure release tune valve
There is emptying structure.
The preferred mode of the above solution is that the decompression control valve also includes intelligent pressure adjustment module, the pressure release
The limiting pressure unlatching value of regulating valve is limited by the intelligent pressure adjustment module.
The beneficial effects of the present invention are: the application on the basis of existing air cushion tank by increasing setting tank pressure stabilizing group
Part, and the internal pressure of the air cushion tank in the course of work is made to keep stablizing by the tank stabipack.In this way,
It due to introducing tank stabipack, is either adjusted before high pressure gas input air surge tank, or slow in air
The height for the cleaning that can effectively guarantee to recoil for ceramic membrane saline water filter is adjusted when the high pressure gas output rushed in tank
Calm the anger body pressure value in the range of setting, to reach in the case where source air pressure is high or the larger situation of fluctuation, remain to protect
Demonstrate,prove the stable purpose of pressure when ceramic membrane recoil.And then reach reduction during the backwash process because backwashing pressure is unstable
It is fixed, especially pressure value it is higher caused by the purpose damaged of ceramic-film tube.
Detailed description of the invention
Fig. 1 is simplified structure diagram of the present invention for the backpurge system of chemical industry for making chlorine and alkali salt refining ceramic membrane.
In the figure, it is marked as air cushion tank 1, tank stabipack 2, pressure transmitter 3, air inlet adjustment valve 4, intelligent pressure tune
Save module 5, back flushing gas delivery pipe 6, from force regulating valve 7, decompression control valve 8, emptying structure 9.
Specific embodiment
It is that provided by the invention a kind of can remain to protect in or the larger situation of fluctuation high in source air pressure as shown in Figure 1
Demonstrate,prove the stable backpurge system for chemical industry for making chlorine and alkali salt refining ceramic membrane of pressure when ceramic membrane recoil.The backpurge system
Including air cushion tank 1, the backpurge system further includes tank stabipack 2, the air cushion tank 1 in the course of work
Internal pressure keeps stablizing by the tank stabipack 2.The application on the basis of existing air cushion tank 1 by increasing
Tank stabipack 2 is set, and the internal pressure of the air cushion tank 1 in the course of work is made to pass through the tank stabipack
2 keep stablizing.In this way, either being carried out before high pressure gas input air surge tank 1 due to introducing tank stabipack 2
It adjusts, or is adjusted when high pressure gas output in air cushion tank 1 and can effectively guarantee to be used for ceramic membrane salt water
The pressure value of the high pressure gas of filter recoil cleaning is in the range of setting, to reach in source air pressure height or fluctuation
In larger situation, the stable purpose of pressure when ceramic membrane recoil is still ensured that.And then reach reduction during the backwash process because
It is unstable for backwashing pressure, especially pressure value it is higher caused by ceramic-film tube damage purpose.
In above embodiment, in order to comprehensively adjust the pressure of the high pressure gas in air cushion tank 1, make the anti-of output
Stamping press reaches more effect, and as mentioned above described in beneficial effect, the application is not only from air cushion tank 1 itself
Pressure adjusting is carried out, also outputting and inputting for gas is adjusted simultaneously, i.e., the tank stabipack 2 respectively includes pressure
Transmitter 3, air inlet adjustment valve 4, from force regulating valve 7 and decompression control valve 8, for air cushion tank 1 progress pressure tune itself
The structure of section is pressure transmitter 3, for being air inlet adjustment valve 4 to the structure being adjusted into pressure, for output gas
It is from force regulating valve 7 and decompression control valve 8 that body, which carries out pressure controlled structure,.The pressure transmitter 3 is arranged in the sky
