Abstract
Disclosed is a deep-purifying bag filter, including from top to bottom: an air-purifying chamber, a filter chamber and an ash bucket which are communicated with each other, wherein an air outlet is arranged on the top of the air-purifying chamber; an air inlet is arranged on the ash bucket; an air distributor is arranged inside the air inlet; the air-purifying chamber and the filter chamber are separated by a tube sheet, on which a frame and a filter bag which are located in the filter chamber are fixed; a blowing hole is opened on the side wall of the air-purifying chamber where an inner blowing tube going through the blowing hole is arranged above the tube sheet; the inner blowing tube is communicated with the air bag through an outer blowing tube and a pulsed ash-cleaning valve is also arranged on the air bag; a reticulated grizzly screen is arranged at the joint of the filter chamber and the ash bucket. The utility model has the gas enter into the deep-purifying bag filter directly from the air inlet of the ash bucket and the clean gas flow out of the filter from the air outlet on the top of the air-purifying chamber. Thereby, not only the ash-cleaning efficiency is improved and the security of using the Cottrell precipitator is enhanced, but the old circumfluence filter and the flow bank of the gas-making system are removed, so that the human and material resources are reduced.
Description
Technical field
The utility model relates to a kind of dry method gas-solid dust arrester that is separated, particularly a kind of deep purifying sack cleaner.
Background technology
Former technology normal pressure gasifying powder coal device dust pelletizing system adopts moderate dedusting, i.e. I and II cyclone dust collectors+circulation cyclone dust collectors.From the coal gas of high temperature of 1# evaporimeter after the I and II cyclone dust collectors are removed dust a large amount of in the coal gas, reclaim heat through WHRS (2# evaporimeter, low-pressure steam heater, feedwater preheater), after entering the further dedusting of circulation cyclone dust collectors then, after the washing of final washing cooling tower, send the battery limit (BL); Final washing cooling tower waste water and electrostatic precipitator washings or flushing water send circulating water for gasification system precipitation and cooling processing together, handle back water and recycle.
According to existing apparatus operation actual conditions, though adopt above-mentioned circulation dust-removing device can further remove dust in the coal gas, because lighter (grain density 100%＜300 order, bulk density 0.8t/Nm of dust in the coal gas
3), the circulation dust-removing device can't reach comparatively desirable dust removing effects, moves after dust is a large amount of, brings back system electrostatic precipitator into, causes electrostatic precipitator entrance concentration higher (static dust-releasing device entrance concentration requirement＜600mg, actual condition reaches about 1g).Because electrostatic precipitator specification requirement restriction, so that do not guarantee of the requirement of outlet dust content less than 10mg.Cause the dust that exceeds standard to bring the back system into, follow-up systems such as desulfurization, compression are all had very important harm, influence the performance of plant capacity.
Simultaneously, the circulating water for gasification system adopts precipitation process, and a large amount of fine dusts float on the water surface, can't realize gravitational settling, and difficult treatment; And precipitation process waste water caused certain pollution to the environment of gasification system, also increased certain man power and material simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of work simplification is provided, and is rational in infrastructure, can deep purifying coal gas, but the sack cleaner of online ash removal.
For achieving the above object, the technical solution adopted in the utility model is: comprise the air-purifying chamber that is interconnected from top to bottom, filter chamber and ash bucket, the top of air-purifying chamber is provided with the gas outlet, ash bucket is provided with air inlet, be characterized in, the inside of air inlet is provided with gas distributor, air-purifying chamber and filter chamber isolate by card, the cage bone and the filter bag that are positioned at the filter chamber are fixed on the card, on the sidewall of air-purifying chamber, offer injection hole, interior winding-up pipe is arranged in the air-purifying chamber by injection hole and is positioned at the upper end of card, interior winding-up pipe is connected with gas bag by outer winding-up pipe, and also be provided with the pulse dust cleaning valve on gas bag, filter chamber and ash bucket junction are provided with a mesh grille.
Also be provided with fixedly connected upper and lower location angle steel in the air-purifying chamber of the present utility model, the drainage nozzles of winding-up pipe is fixedlyed connected vertically downward and with last location angle steel in making, and card is fixedlyed connected with following location angle steel; Be equipped with on the sidewall of ash bucket and purge mouth, and ball valve also is installed in the exit of ash bucket; The lower end of ash bucket also is provided with the secondary ash bucket that is connected with ash bucket, the secondary ash bucket is provided with seal, broken arch mouth reaches and break the Arch-Breaking Device that the arch mouth is connected, Arch-Breaking Device is connected by broken arch ball valve 24 with broken arch mouth, and also is provided with Unloading ball valve at the cinder-discharging port place of secondary ash bucket; The top of air-purifying chamber also is provided with safety and diffuses mouth; Also offer manhole and following manhole in air-purifying chamber and the filter chamber respectively.
Because coal gas of the present utility model directly enters the deep purifying sack cleaner from the ash bucket air inlet, after the gas distributor uniform distribution, enter pocket type by the further deep purifying of filter bag, clean coal gas flows out deduster from gas outlet, air-purifying chamber top, enter to send the battery limit (BL) after final washing cooling tower washs; Final washing cooling tower waste water send biochemical treatment or directly recycles in this device.Like this, not only improve efficiency of dust collection, increased the security that electrostatic precipitator is used, and removed former circulation dust-removing device and gasification system sedimentation basin, reduced investment and occupation of land, also reduced the man power and material simultaneously.
