Description
Technical field
The present invention relates to the method for a kind of peculiar odor treatment spray water tank water filtration.
Background technology
The application of Primary processing shop peculiar odor treatment equipment inhales taste to improving pipe tobacco, and the assorted gas effect of removal is remarkable.By peculiar odor treatment equipment, peculiar smell collection is carried out to the waste gas of each process point, because the waste gas dustiness of these process point is comparatively large, cause water quality poor.
In existing technology: the water after filtration through original filter front intercept valve and original DN50Y type filter, is transported to spray water stain atomization by water pump from spray column water tank by sewage.
Existing problems: cause the DN50FIG-Y type filter before spray pump to block, water pump insufficient water, shower water pressure is reduced to 1.5bar, cannot meet shower water pressure request.Original DN50Y type filter, because the impurity blocking in water, can not meet the flow needs of water pump, cause water pump discharge pressure to reduce, affect spraying effect, need the cleaned filter of frequent shutdown, cause equipment effectiveness to reduce, and product is inhaled taste and produced fluctuation.
Summary of the invention
For solving the deficiency that prior art exists, the invention discloses the method for a kind of peculiar odor treatment spray water tank water filtration,
For achieving the above object, concrete scheme of the present invention is as follows:
A method for peculiar odor treatment spray water tank water filtration, comprises the following steps:

Two groups of screen packs in box filter, ensure filter effect, meet one piece clean time another block can effectively work.
Box filter is provided with the long glass-tube liquid level meter of two pieces 700mm before and after screen pack, by the difference in height of glass-tube liquid level meter, can determine screen pack cleaning cycle.The newly-increased box filter filtering efficiency realizing filter screen quantizes controlled, thus improves the normal operation continuously of main process equipment.
The box filter top survivor of a murder attempt adopts active press fastening type locking mechanism, convenient and practical, and bottom is installed by floss hole, meets box filter cleaning requirement when overhauling.
First waste gas is carried out rough dusting through spray column by Primary processing shop peculiar odor treatment equipment, because in waste gas, dust content reaches 70-80mg/m3, gas with foreign flavor carries out dust-filtering by Cemented filling to spray column, reach dust <5mg/m3, simultaneously ammonia level < 5mg/m3.Then, gas is again by DLMP5/6/18 taste removal system, and remove organic peculiar smell and small-scale inorganic class peculiar smell, final purification gas passes through smoke stack emission.
Beneficial effect of the present invention:
Sewage one tunnel from spray column water tank through original filter front intercept valve and original DN50Y type filter; Water after filtration, from newly-increased box filter water inlet, water outlet pipe valve, through newly-increased box filter by after sewage water filtration, is transported to nozzle by spray pump and is atomized, meet sewage water filtration ability needs by another road.Because present negative pressure state in the spray column water tank course of work, law of connected vessels is adopted to solve the water supply problem of filter screen cleaning in production process.
