The novel grey water recycling device for the coal gas generating system can be used for solving the problems that the traditional grey water recycling device is low in energy utilization rate and complex in equipment.
Description
Technical field:
The present invention relates to a kind of device of gas recovery generation systems buck, can be used for gas generating system grey water purification with pressure and recovery.
Background technology:
Gas generating system ash apparatus for recovering adopts classification throttling vacuum flashing mode that the ash in buck with pressure is separated with water more at present, after ash removes, water is reclaimed.There are two problems in classifying screen stream mode: the one, and reducing pressure by regulating flow has caused the loss of energy, and the 2nd, when grey water pressure is higher, to adopt 2 grades of above throttling flash systems, device is comparatively complicated, needs a kind of new device to address these problems.
Summary of the invention:
Large for current gas generating system ash apparatus for recovering power loss, the problem that system is comparatively complicated, the invention provides a kind of new gas generating system ash apparatus for recovering.
The present invention is by the following technical solutions:
Technology of the present invention comprises energy withdrawal machine and the generator connecting mutually with it, pressure flash tank, vacuum flasher, slurry tank, grey water pot, vacuum pump, vacuum cooler-condenser, scrubber tower, reflux exchanger, light grey water pump, dense grey water pump and high pressure ash water pump.
Come the high pressure buck of self-gasifying device first to enter energy-recovering machine, driving-energy recycling machine rotor drives the generator being connected with energy-recovering machine, after the work done in energy-recovering machine of high pressure buck, pressure drop are low, enter flash distillation in pressure flash tank, after gas-liquid separation, liquid enters vacuum flasher flash distillation again, liquid after flash distillation enters slurry tank by fluid-tight pipeline, and the liquid in slurry tank is inhaled into and in the pipeline of fluid-tight pipeline, forms the vacuum tightness that fluid column keeps vacuum flashing system.The gas of pressure flash tank is directly sent into scrubber tower, and the gas of vacuum flasher is separated through vacuum cooler-condenser, after vacuum pump pressurization, sends into scrubber tower.The liquid of slurry tank, vacuum flasher, vacuum cooler-condenser and filter is all delivered to slurry tank sedimentation, and the light buck in upper strata is by grey water pot and light buck pumping scrubber tower top, and the dense buck in slurry tank bottom is sent battery limit (BL) by solid after dense grey water pump, filter.
Accompanying drawing explanation:
