Embodiment two
The working method of the closed circuit internal circulation apparatus of gas collection in a kind of separation of solid and liquid process, it is characterised in that including with
Lower step：
Liquid containing solid particle polluter is separated by solid-liquid separation by cluster type power back-blowing filter, to remove solid
Grain, solid particle are filtered from outside to inside by filter element, filter cake are formed in filter element surface, when filter cake reaches certain thickness
Or filter needs the removing for carrying out filter cake online when reaching certain filtration pressure difference at this time；It is first turned on pressure/drying valve,
Cluster type power back-blowing filter from outside to inside carries out filter element using compressed gas the drying of the discharge and filter cake of raffinate, then
Filter back-flushing valve door and slag-discharging valve are opened, carries out instantaneous blowback from inside to outside to remove filter cake, it is anti-by gas moment
Tension is blown, filter cake drains into the slurries drying machine of lower section；Pressure drying and blowback deslagging stage, pressure-regulating valve and pressure transmitter
The chain pressure for adjusting pressure/drying/purge gas, check-valves are used for preventing liquid countercurrent to compressed gas storage tank.
A large amount of gas can be consumed in pressure drying and blowback tapping process, causes residual liquid partly atomized in filter cake,
It needs to carry out interception collection to this partly atomized liquid, pressure/dry gas passes through slurries by purified liquor outlet pipeline, blowback air
The exhaust line of drying machine enters gas-liquid separator after carrying out unified collection, and droplet is through coalescing element coarse separation, gas row
To the Drechsel system at rear, by the part toxic and harmful gas in spray assemblies spray-absorption gas, gas is washed through spray
Enter two level gas-liquid separator after washing and carry out two level gas-liquid separation, the gas after separation is discharged into High-Performance Gas Filter, after processing
It can continue reuse, the filter cake slurry in slurries drying machine pushes material by the slag conveyer of bottom, and filter cake is received
Collection.
Finally, it should be noted that：The closed circuit interior cycle of gas collection in this separation of solid and liquid process has been shown and described above
The basic principles and main features and advantage of device；It should be understood by those skilled in the art that the design is not by above-described embodiment
Limitation, the above embodiments and description only describe the principle of design and technical process, are not departing from the design essence
Under the premise of refreshing and range, the design will also have various changes and improvements, these changes and improvements both fall within claimed sheet
In the range of innovative design, scope of the claimed is by appended claims and its equivalent circle.
