In a kind of separation of solid and liquid process the closed circuit internal circulation apparatus of gas collection method of work it is characterised in that include with Lower step:
Liquid containing solid particle polluter carries out separation of solid and liquid by cluster type power back-blowing filter, to remove solid Grain, solid particle is filtered from outside to inside by filter element, forms filter cake in filter element surface, when filter cake reaches certain thickness Or filter is when reaching certain filtration pressure difference, now need to carry out the removing of filter cake online;It is first turned on pressure/valve is dried, Cluster type power back-blowing filter carries out the discharge of raffinate and the drying of filter cake from outside to inside using compressed gas to filter element, then Open filter back-flushing valve door and slag-discharging valve, from inside to outside carry out instantaneous blowback to remove filter cake, anti-by gas moment Blow tension force, filter cake drains in the slurries drying machine of lower section;Pressure is dried and blowback deslagging stage, pressure-regulating valve and pressure transmitter The chain pressure adjusting pressure/drying/purge gas, check-valves is used for preventing liquid countercurrent to compressed gas storage tank.
Substantial amounts of gas can be consumed in pressure drying and blowback tapping process, cause residual liquid partly atomized in filter cake, Need this partly atomized liquid to be carried out intercept to collect, pressure/dry gas pass through purified liquor outlet pipeline, and blowback air passes through slurries The exhaust line of drying machine enters gas-liquid separator after carrying out unifying to collect, and droplet is arranged through coalescing element coarse separation, gas To the Drechsel system at rear, by the part toxic and harmful in spray assemblies spray-absorption gas, gas is washed through spray Enter two grades of gas-liquid separators after washing and carry out two grades of gas-liquid separations, the gas after separating enters High-Performance Gas Filter, after process Reuse can be continued, the filter cake slurry in slurries drying machine is pushed to material by the slag conveyer of bottom, and filter cake is received Collection.
Finally it should be understood that the closed circuit interior circulation of in this separation of solid and liquid process gas collection has been shown and described above The general principle of device, principal character and advantage;It should be understood by those skilled in the art that, the design is not subject to above-described embodiment Limit, principle and the technical process that design is simply described described in above-described embodiment and specification, without departing from the design essence On the premise of god and scope, the design also has various changes and modifications, and these changes and improvements both fall within claimed basis In the range of innovative design, scope of the claimed is by appending claims and its equivalent circle..
