Background technology
At present, fine coal at Coal Chemical Industry production field pressurizes in continuous gasification industrial processes, gasification furnace synthesis gas is directly entered synthesis gas washing tower after one-level Venturi scrubbing and washs, it is more because synthesis gas is carried secretly coal ash, when changing particularly in gasification furnace start-up and load adjustment, easily cause the blocking of rear processing apparatus, seriously constrain the long-period stable operation of device.
Utility model content
For overcoming above-mentioned the deficiencies in the prior art, the utility model discloses a kind of gasification furnace Novel synthesis gas dust dust pelletizing system.
For achieving the above object, this utility model adopts following technical proposals:
A kind of synthesis gas dust pelletizing system, including the one-level Venturi scrubber being connected with gasification furnace syngas outlet, coupled logical cyclone separator it is provided with after one-level Venturi scrubber, the outlet of described cyclone separator is connected with two grades of Venturi scrubbers, and the synthesis gas of two grades of described Venturi scrubber outputs sends into synthesis gas washing tower.
Further, the liquid outlet of described cyclone separator drains into hp flash drum through air relief valve, and the pulp water after described hp flash drum flash distillation enters slag water treatment system, and flash gas sends into high pressure flash stripper.
Further, the bottom of described synthesis gas washing tower is connected by the porch of a Quench water pump and two grades of Venturi scrubbers.
Further, the pipeline that scrubbing tower feed pump is connected with one-level Venturi scrubber entrance is provided with a control valve.
Further, the bottom of described high pressure flash stripper is connected with the porch of one-level Venturi scrubber by a scrubbing tower feed pump.
Further, the pipeline that described scrubbing tower feed pump is connected with the entrance of one-level Venturi scrubber is provided with a control valve.
Work process of the present utility model is as follows:
First, one-level Venturi scrubber is set in gasification furnace syngas outlet, by scrubbing tower feed pump, the washings in high pressure flash stripper are sent into one-level Venturi scrubber, it is atomized under the effect of Venturi scrubber, condenses, make the grit (dust) in synthesis gas and atomization aqueous phase cohesion, form bigger dust-laden drop, precipitate and separate, reach the purpose given a dinner of welcome；
Secondly, after one-level Venturi scrubber, cyclone separator is set, after synthesis gas after the washing of one-level Venturi scrubber enters cyclone separator, synthesis gas flow is introduced tangentially into formation rotary motion inside multicyclone apparatus, under the effect of centrifugal intertia force, solid particle, drop get rid of to equipment wall surface, dust-laden drop is easily separated, thus reaching to separate the effect of dedusting.The liquid of cyclone separator drains into hp flash drum through air relief valve, and after flash tank flash distillation, pulp water enters slag water treatment system, and flash gas sends into high pressure flash stripper；
Gas after cyclone separator separation dedusting enters two grades of Venturi scrubbers, by Quench water pump, the washings in synthesis gas washing tower are sent into two grades of Venturi scrubbers, again wash atomization, cohesion, the tiny grit (dust) still carried secretly in synthesis gas and atomized water is made fully to condense, form dust-laden drop, precipitate and separate, reach the purpose again given a dinner of welcome；
Synthesis gas after two-stage Venturi scrubbing sends into synthesis gas washing tower, fully buffering, washing under the effect of synthesis gas washing tower, separate after, crude synthesis gas sends into transformation system.
The beneficial effects of the utility model are:
This utility model reduces the coal ash entrainment of synthesis gas gas further, it is to avoid because synthesis band of gas ash causes the blocking of rear processing apparatus to affect long period safe and stable operation.
Accompanying drawing explanation
