Specific embodiment

The utility model is achieved in that knot below for capacity coke oven dedusting and sticky tar absorption integrated apparatus Attached drawing is closed to illustrate.

See that Fig. 1, Fig. 2, the utility model adsorb integrated apparatus for capacity coke oven dedusting and sticky tar, is by entering the wind Burnt slot 5, scraper ash-transmission machine 6, cigarette are stored up in concetrated pipe 1, import Pneumatic butterfly valve 2, stickum absorbing unit 3, flat focusing mechanism 4, top Gas flows case 7, flows baffle plate assembly 8, pulse spraying equipment 9, filter element 10, exhaust gases passes 11, air-purifying chamber 12, flowering baffle 13, top blind flange 14, outlet Pneumatic butterfly valve 15, outlet air concetrated pipe 16, filter box 17, bottom grid beam 18, bottom great Chu coke slot 19, electronic format feeder 20 and stickum adsorbent equipment shell 21 form, and air inlet concetrated pipe 1 is arranged in filter box 17 On, import Pneumatic butterfly valve 2 is equipped in the entrance of air inlet concetrated pipe 1；Filter box 17, bottom great Chu coke slot 19 and electronic format Batcher 20 is arranged in bottom grid beam 18；It is equipped with filter element 10, flue gas flow equalizing case 7 in filter box 17 and flows baffle Component 8；Equipped with the exhaust gases passes after stickum absorbing unit 3 and stickum absorption in stickum adsorbent equipment shell 21 11, the top of stickum absorbing unit 3 is equipped with top and stores up the peaceful focusing mechanism 4 of burnt slot 5, and the top that burnt slot 5 is stored up at top, which is equipped with, scrapes Plate cinder conveyer 6, the top of deduster filter box 17 are equipped with outlet air concetrated pipe 16, and the exit of outlet air concetrated pipe 16 is equipped with outlet Pneumatic butterfly valve 15；The top of flue gas flow equalizing case 7 is equipped with flowering baffle 13 and top blind flange 14, and air-purifying chamber 12 is arranged in 13 He of flowering baffle Between top blind flange 14, pulse spraying equipment 9 is connected to air-purifying chamber 12.

The utility model adsorbs integrated apparatus for capacity coke oven dedusting and stickum, large-scale coal chemical enterprise top dress or Side fills coke oven in the flue gas that operation is discharged containing superfine dust and sticky tar material, and this flue gas is entering bag-type dusting Stickum must be removed before device filtering, sack cleaner could be used to purify coke oven flue gas, this integrated purifying device uses Coke adsorbs the stickum in flue gas, removes a large amount of tar and superfine dust in flue gas.Since Coke density is small and surface It is very extremely advantageous to the sticky goods and materials of absorption greatly for honeycomb, the specific surface area of coke, using 20-40mm equivalent diameter in device Coke granule, the gas passage formed after the coke natural packing of this specification is winding to be conducive to flue gas in labyrinth-like and inhales Addendum provides close contact and adsorbs and filter stickum and tiny dust particles.

Coke oven flue gas carries out double purification by being directly entered pulse bag type dust collector after absorption.It is come out from tar absorber Flue gas initially enter the separation chamber Jun Yachu of sack cleaner, the larger particles dust in flue gas is since reduction of speed is weightless and is being confused Impact and gyroscopic action, particle are fallen into the ash-pit of lower part in the baffle of palace formula, and flue gas obtains double purification.Flue gas enters pocket type and removes Filter bag is passed through for tiny dust detention in the outer surface of filter bag, purified flue gas with uniform speed after dirt device filter box Enter outlet air concetrated pipe by Gas-cleaning box and is connected to dust pelletizing system.

When the utility model is for capacity coke oven dedusting and sticky tar absorption integrated apparatus work:

High temperature containing dust and stickum flows into stickum absorption by import pneumatic operated valve valve 2 from air inlet concetrated pipe 1 Unit 3.

The coke of dry 20-40mm particle diameter is transported on the outside of the present apparatus that underground is by burnt slot by coke oven, through under overfocus slot The outlet oscillating feeder in portion send to bucket elevator and is diverted to scraper ash-transmission machine 6 at the top of the present apparatus, and coke is transported to top It in portion's coke storage tank 5, adsorbs and uses as flue gas, in coke into storage tank in transmission process, flat coke installation 4 starts, and can make to store up Slot increases reserves.

The electronic format feeder 20 that start lower part in just dress coke stores coke into great Chu coke slot 19, when lower part material position After meter issues signal, electronic format feeder 20 is out of service, illustrates that storage coke expects to seal enough in big storage tank 19, electronic format is given After material machine 20 is out of service, coke is gradually accumulated to coke bin in each absorbing unit 3 and fills, and top level-sensing device issues electric signal simultaneously Coke situation is filled depending on each unit in hole, stops coke transport system transformation.It is burnt for adsorbent equipment replacement two sides that burnt 5 capacity of slot is stored up at top Charcoal.

The adsorbable 80000-200000m3/h of flue gas containing stickum of the utility model integration adsorbent equipment, initial resistance 1800Pa can rise to 3000Pa or so using resistance after the several months, and needing replacing coke reduces running resistance, keep flue gas system Normal paved set monitors pressure difference change situation in the pressure at both sides transmitter of absorbing unit at any time.

To start electronic format feeder when replacing coke, the feed ability of every format feeder is 0.16m3/min, The achievable replacement of 8min.One deduster air inlet is set between two adjacent groups absorbing unit, and two adjacent groups absorbing unit is set One group of air-out passage 11 is set, inlet/outlet air concetrated pipe 1/16 is arranged in cabinet two sides.

The utility model is overall structure, dedusting ground for capacity coke oven dedusting and sticky tar absorption integrated apparatus Arrangement of standing is more reasonable, effectively reduces the process equipment of dedusting earth station, reasonable in design, technical perfection weight, operation resistance Power is small, occupied area is small, high reliablity, equipment investment are small, is the ideal facility of coke oven dust and stickum absorption.
