Embodiment two
The method of work of the closed circuit internal circulation apparatus of collection and confinement of gases during a kind of solid-liquid separation, it is characterised in that include following step
Rapid:
Liquid containing solid particle polluter carries out solid-liquid separation by cluster type power back-blowing filter, to remove solid particle, Gu
Body granule is filtered from outside to inside by filter element, forms filter cake in filter element surface, when filter cake reaches certain thickness or mistake
When filter reaches certain filtration pressure difference, now need to carry out online the removing of filter cake；It is first turned on pressure/dry valve, boundling
Formula power back-blowing filter uses compressed gas that filter element carries out the discharge of residual liquid and being dried of filter cake from outside to inside, then opens
Filter blowback valve and slag-discharging valve, from inside to outside carried out instantaneous blowback to remove filter cake, opened by the blowback of gas moment
Power, filter cake drains in the serosity drying machine of lower section；Pressure is dried and the blowback deslagging stage, and pressure-regulating valve and pressure transmitter are chain
The pressure of regulation pressure/be dried/purge gas, check-valves is used for preventing liquid countercurrent to compressed gas storage tank.
Pressure is dried and can consume substantial amounts of gas in blowback tapping process, causes residual liquid partly atomized in filter cake,
Needing to carry out this partly atomized liquid intercepting to collect, pressure/dry gas is by purified liquor outlet pipeline, and blowback air passes through serosity
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 gas washer at rear, by the part toxic and harmful in spray assemblies spray-absorption gas, gas is washed through spray
Entering two grades of gas-liquid separators after washing and carry out two grades of gas-liquid separations, the gas after separation enters High-Performance Gas Filter, after process
Can continue reuse, material is pushed by the filter cake slurry in serosity drying machine by the slag carrier of bottom, and filter cake is received
Collection.
Last it should be understood that the closed circuit interior circulation of collection and confinement of gases during this solid-liquid separation has been shown and described above
The ultimate principle of device, principal character and advantage；Skilled person will appreciate that of the industry, the design is not by above-described embodiment
