Description

A kind of environmental protection and energy saving coal gas generating unit

Technical field the utility model belongs to coal gas generation facility technology field, is specifically related to a kind of environmental protection and energy saving coal gas generating unit.

Background technology is present, generally use gazogene be gas generating station, comprise motor, induced draft fan, producer gas generator, two vertical tube washer, electric coke catcher, washing tower and drop catcher, the gas exit of said producer gas generator is communicated with the gas inlet of two vertical tube washers, the gas exit of two vertical tube washers is communicated with the gas inlet of electric coke catcher, the gas exit of electric coke catcher is communicated with the gas inlet of washing tower, and the gas exit of washing tower and drop catcher gas inlet are communicated with; Said washing tower bottom is cylindrical structure, and washing tower top is provided with the washing water nozzle.The coal gas that the gas furnace of prior art produces is inhaled through static and is caught through two vertical tube washing, and then through the washing tower washing, treated coal gas is for using.There is following technological deficiency in the gazogene of prior art: the one, and the washing water consumption is big, per hour approximately produces washes 150～200m according to incompletely statistics ³Though can recycle, but, when the washing water temperature is too high, just needs to replenish a large amount of cold water and lower the temperature when gas yield increases, the result produces a large amount of washes dischargings, owing to contain the aldehydes matter height in the washes, cause river and phreatic pollution in wide area, the regional remission time that is polluted needs 5 years at the soonest, severe patient is for 30 years, and the consequence that is caused is quite serious; The 2nd, because the washing water consumption is big, the running cost height; In addition, the tar rate of recovery is also low.

The summary of the invention the purpose of this utility model provides the environmental protection and energy saving coal gas generating unit that a kind of washing water consumption is few, pollution-free, running cost is low, to overcome the deficiencies in the prior art.

For achieving the above object, the utility model environmental protection and energy saving coal gas generating unit, it comprises motor, induced draft fan, producer gas generator, electric coke catcher and drop catcher, its main points are that it also is provided with fly-ash separator, quencher and cooling fly-ash separator, the gas exit of said producer gas generator is communicated with the gas inlet on fly-ash separator top, the vertical gas exit of fly-ash separator is communicated with the vertical gas inlet of quencher, and the gas exit of quencher bottom is communicated with the gas inlet of electric coke catcher.The gas exit of electric coke catcher is communicated with the gas inlet of cooling fly-ash separator bottom, and the gas exit and the drop catcher gas inlet of cooling dust remover roof are communicated with, and drop catcher top is provided with the gas outlet tube that is communicated with the coal gas main pipe line.

Said fly-ash separator is interlayer, awl end exocentric structure, and water makes the coal gas cooling at the interlayer internal recycle, and suspended substance is met cold cooling becomes particle, collects along awl end centrifugal settling.

Said quencher is double standpipe structure, the two ends of double standpipe are respectively equipped with upper and lower minute gas tank, be provided with the gas distributing tee pipe above the branch gas tank of saying, Y-tube is communicated with the gas inlet pipeline, under divide gas tank to be provided with escape pipe, coal gas enters respectively in the standpipe after entering the branch gas tank, through natural wind cooling cooling.

Said electric coke catcher is end to end placed in-line two groups.Catch Jiao through twice, the tar rate of recovery is improved greatly.

Establish awl end sedimentation dust-precipitator in the bottom of said cooling fly-ash separator, establish 24 standpipes in the cooling fly-ash separator, after coal gas entered standpipe from the bottom of cooling fly-ash separator, through the cooling dedusting, purified coal gas entered drop catcher from the escape pipe at the top of cooling fly-ash separator.

The utility model modern design, be easy to install, easy to use, be interlayer internal cooling fly-ash separator and natural air cooled quencher owing to change two vertical tube washers, change spray scrubber for the cooling fly-ash separator, saved a large amount of washing cooling waters.Have the advantages that nature cooling, centrifugal dust-removing, static are given a dinner of welcome, effectively avoided the generation of washes, greatly reduce running cost, and can reclaim a large amount of coal tar.Detect through authoritative department, recirculated water includes suspended substance and total solid is respectively: 2 and 10mg/L, do not contain phenol, tar, ammonia, sulfide, prussiate and sulphur, and COD is: 5～15mg/L, water quality reaches the breeding water standard, has reached international most advanced level.The utility model level of automation height, operating environment are good, coal gas vaporization efficiency height, the calorific value height of producing, production cost is low, foreign matter content is few, every indexs such as its environmental protection, energy-conservation and gas quality all reach the GB requirement, it is a kind of comparatively ideal gazogene, have vast market prospect, be suitable for enterprise, household application.
