Abstract
The invention relates to a backward flow type tail gas treatment device comprising a tail gas exhaust port. The backward flow type tail gas treatment device is characterized in that the tail gas exhaust port extends into a liquid tank; a plurality of layers of filter screens provided with a plurality of rows of transverse through grooves are arranged on the level part of the liquid tank; and the filter screens are arranged at intervals. Through introducing tail gas exhausted from boilers and other industrial process equipment to liquid, the invention can clean away large amount of dust, sulfide and other pollutants carried in the tail gas, thereby self filtering can be achieved without the need of external power.
Description
Technical field:
The present invention relates to a kind of backward flow type tail gas treatment device.
Background technology:
At present; Various boilers not only are widely used in industry, in daily life, also are used more and more widely, and the discharging of boiler exhaust gas also is the problem that people pay close attention to always; Its exhaust filtering is unclean; Must cause the destruction to the Nature, other harmful material exhaust filterings are unclean, can damage the Nature yet.So; A large amount of devices to the tail gas clean-up processing has appearred at present, like a kind of double-tower type water spray device for purifying and treating tail gas, though this device can play certain filter effect; But the water spray power-equipment that needs high-power, manufacturing cost is high, water pipe often stops up; Also all cause the obstruction of filter in addition easily, and can't operate as normal just like the device for purifying and treating tail gas of drainage type and dry-powder-type, and its dedusting not thoroughly, the difficulty of removing contamination.
Summary of the invention:
The object of the present invention is to provide a kind of backward flow type tail gas treatment device, this backward flow type tail gas treatment device is not only simple in structure, reasonable in design, and good filtration effect, never stops up, removes contamination conveniently.
The present invention realizes through following technical scheme:
Backward flow type tail gas treatment device of the present invention; Comprise the tail gas outlet; It is characterized in that: said tail gas outlet stretches in the liquid tank, and said liquid tank liquid face is provided with several layers and has the screen pack of several horizontal rows to groove, is provided with at interval between said each layer screen pack.
The present invention is through will feeding the liquid from the tail gas that equipment such as boiler, industry are discharged, thereby can remove pollutants such as the amounts of dust of carrying secretly in the tail gas, sulfide, and tail gas rises under buoyancy function in liquid from the bottom up; Liquid bubble is increasing, and during through the screen pack orlop, liquid bubble continues to rise under buoyancy function; Must be through the groove of screen pack; Big liquid bubble clashed into and stir after become little liquid bubble, just can pass groove then, crossed the groove of orlop screen pack after; Owing to be provided with at interval between each layer screen pack; Liquid bubble rises in liquid again and becomes big, after descending most the second layer, diminishes again, and uphill process is also two-layer the same with the front again; So a liquid bubble floats before the liquid surface; Big through repetitious like this change, diminish; Pollutant such as dust, sulfide further contacts with liquid, because the effect of liquid adsorption power makes its sinking, is discharged into the just more more cleaning of airborne gas; Need not exterior power thereby play, get final product the effect of inherent filtration.
Description of drawings:
Fig. 1 is an organigram of the present invention;
Fig. 2 be among Fig. 1 screen pack overlook organigram;
Fig. 3 is the A-A profile of Fig. 2.
The specific embodiment:
Backward flow type tail gas treatment device of the present invention comprises boiler exhaust gas outlet 1, and boiler exhaust gas outlet 1 stretches in the liquid tank 2, and liquid tank liquid face is provided with several layers and has the screen pack 3 of several horizontal rows to groove 4, is provided with at interval between each layer screen pack.Through will feeding the liquid from the tail gas that equipment such as boiler, industry are discharged, thereby can remove pollutants such as the amounts of dust of carrying secretly in the tail gas, sulfide, tail gas rises under buoyancy function in liquid from the bottom up; Liquid bubble is increasing, and during through the screen pack orlop, liquid bubble continues to rise under buoyancy function; Must be through the groove of screen pack, big liquid bubble clashed into and stir after become little liquid bubble, just can pass groove then; After having crossed the groove of orlop screen pack; Liquid bubble becomes again greatly, after descending most the second layer, diminishes again, and uphill process is also two-layer the same with the front again; So a liquid bubble floats before the liquid surface; Big through repetitious like this change, diminish; Pollutant such as dust, sulfide further contacts with liquid, because the effect of liquid adsorption power makes its sinking, is discharged into the just more more cleaning of airborne gas; Need not exterior power thereby play, get final product the effect of inherent filtration.
After the filtration of a period of time; Can stop up groove by a large amount of dirts of deposition on the screen pack; In each groove 4, all be equipped with from top to bottom and scrape dirty bar 5, so, can remove the dirt in the screen pack groove as long as laterally move around along screen pack through scraping dirty bar; Thereby play fast, cleaning filter net easily, realize never stopping up, time saving and energy saving; In addition, this scrapes the effect that dirty bar 5 also plays stirring, and the liquid bubble of tail gas is fully contacted with liquid.
Remove the dirt in each layer groove for ease, horizontal groove 4 in the vertical directions of each of each layer screen pack 3 are arranged side by side.
For the disposable dirt that can remove all layers, all row's screen pack grooves; Respectively scraping dirty bar 5 links into an integrated entity through the vertical pole 6 that is arranged on orlop screen pack below; Only needing this moment once can be clean with the dirt removal of all row grooves, convenient, more quick.
In order to enter more swimmingly in the liquid tank, the tail gas outlet preferably stretches in the liquid tank 2 obliquely.
For the dirt that enters in the liquid tank can be collected and remove preferably, liquid tank preferably is funnel-form.
During wherein the screen pack 3 of several layers submerges liquid, play the effect of filtering dirt better like this.
In order to filter better; Be furnished with several row on each layer screen pack and have several rows' horizontal groove, be equipped with in each groove and scrape dirty bar 5, the dirty bar top of scraping of every row connects by a vertical pole; Each vertical pole is linked into an integrated entity by a push rod 7; Be equipped with the vertical pole 6 that dirty bar is respectively scraped in connection at each layer, the toggle 9 through being arranged on limit portion drives about it and moves back and forth, and plays groove dirt and the well-beaten effect of removing.
In addition, above screen pack, be covered with hood 8 in order to tail gas is discharged into the high-altitude.Be provided with sewage draining exit 10 so that get rid of the dirt that is deposited on the liquid tank bottom in liquid tank 2 bottoms.
Remarkable advantage of the present invention: be provided with to play through the interval between each layer screen pack and need not the effect that outer power can be realized inherent filtration; Through push rod, vertical pole under the toggle drive and the effect of scraping dirty bar, realize the purpose that this filter never stops up.
