Description
Technical field
The utility model relates to purifier field, in particular to a kind of spray column of filtering biological matter fuel gas and dust.
Background technology
The flue gas that consumer waste incineration produces, national Specification adopts sack cleaner to filter, and bag-type dusting has dry method, semidry method and wet method three kinds, and current China adopts semidry method bag-type dust mostly.In practice, flue gas is reduced to 139 DEG C will condense (steam becomes water droplet), easily causes smoke-dust moist and sticks with paste filter bag, finally bursting filter bag and cause dedusting failure.Therefore, existing house refuse semidry method sack cleaner has electrical heating one, to prevent flue gas to be reduced to less than 140 DEG C, generally all remains on more than 150 DEG C.Just because of increase the device having heating, the cost of the sack cleaner of 1 75t boiler emission flue gas (day process 600t rubbish) is generally 8,500,000 yuan-1200 between ten thousand yuan.
The height of above-mentioned deduster cost, the flue gas ash removal for villages and towns in rural areas domestic rubbish disposal is inapplicable.A Biogas station is built in rural area centered by certain town, and raw material can be rubbish and stalk, and for rubbish, day disposal of refuse 100t scale, gross investment about 1,000 ten thousand yuan, if a greater part of investment amount has been spent in dedusting, that just cannot organizational system gas station.Perhaps someone produces such idea: can by the steam produced when control rubbish or gasifying stalk, as by raw material stoving, moisture is not had in gas, does is dedusting just no longer difficult to process? in fact according to the principle of gas processed, the steam produced when controlling gasification is very difficult.The principle of gas processed is as follows: all solids living beings are as house refuse, stalk, branch bavin etc., they are moisture content about 10% time, the percentage by weight of its hydrocarbon oxygen (C, H, O) transfers mol ratio (mol volume ratio) to, no matter be house refuse, stalk, branch bavin, its C, H, O ratio is all C substantially

From above formula, 3 O are sent on the equal sign left side

1 O is sent on the equal sign left side
2molecule, obtains 5 gas molecules (identical with above formula), but does not have H on the right of equal sign
2o molecule, does not produce water.
It can thus be appreciated that the moisture in the gas that gasification of biomass obtains, is not only decided by the moisture content of fuel, it is also relevant with the gasifying agent (oxygen, air, steam etc.) sent into.In fact, interlock is had can not to control to obtain the moisture content of gas even if send into amount of oxygen with feeding fuel quantity, because the moisture content of fuel is unstable.The weight signal of fuel can be measured, but the fuel of same weight, high C, H, O is wherein just relatively few for moisture content, and the oxygen that interlock is given is joined by weight of fuel, and the oxygen so sent into is just on the high side, will increase the water content in gas.
Perhaps someone expects adopting the mode of electric precipitation to remove dust, but electric precipitation is not only afraid of oxygen but also water funk, oxygen content more than 2% by automatic cut-off power, and the oxygen content of the biological fuel gas that gasification furnace obtains reaches 5-6% sometimes, electric cleaner is water funk is because water can make electric cleaner short circuit, and the gas obtained after biomass combustion contains oxygen, containing water unstable, therefore, electric precipitation is inapplicable.
In addition, for the flue dust that coal combustion produces, although cyclone dust collectors can remove 99% of dust, but the principle of cyclone dust removal relies on inertia and speed that particle is thrown to barrel to fall collection, and biomass ash is light especially, the biomass ash that a part of particle is large is thrown to barrel and falls collection in cyclone dust collectors, also has the tiny light dust of nearly half can not be thrown to barrel, cannot collect, so cyclone dust removal is also inapplicable.
