Abstract

The utility model relates to a smoke prevention and dust removal apparatus with a flush water-bed circulation water curtain, which belongs to a type of a coal-fired boiler and a cement furnace dust remover. The utility model adopts a water tank supported by a holder. Sediment cone buckets are orderly arranged on the bottom of the water tank, and the lower ports of the cone buckets are respectively provided with slagging butterfly valves. A flue inlet is fixed at the front upper part of the water tank, two keg floats are articulated on the front wall, and a floating barrier is connected with and supported by two keg floats. A water tank cover is provided with a water spraying long pipe, and the water tank is provided with a gas water separator composed of a tank body, a gas water isolation page plate package, a flue outlet and a water pan. The lower part of the back side of the gas water separator is communicated with the water tank, and the lower port of the water pan is inserted in the water of the water tank. The utility model has the characteristics of small area occupation, and good dust removing effect.

Description

Impulse water bed circulation water curtain device for abatement of smoke and dust

The utility model belongs to coal-burning boiler, cement kiln deduster class.

Present coal-burning boiler, cement kiln produces a large amount of flue dust when burning, air is caused very serious pollution, in order to purify flue dust, that once promote to be used has gallet water curtain dust collector, Venturi tube water dust scrubber big because of floor space, the reason that the complex structure cost is high, that use in reality and few.

The purpose of this utility model is: provide a kind of floor space impulse water bed circulation water curtain device for abatement of smoke and dust little, simple in structure, good dedusting effect, that easily used by popularization.

Technical measures of the present utility model are: adopt the water tank by bracket supports; Be the sediment awl bucket that is arranged in order at the bottom of the water tank, the lower port of each awl bucket is equipped with the sediment butterfly valve respectively; Be fixed with into mouth in the front upper place of water tank, on the antetheca of water tank, be hinged with two keg floats, connect the floating barrier that is supported with a strip on the keg float; The water spray long tube is housed on tank lid; The gas and water separator of being made up of the drip pan of the outlet flue on the gas-water separation page or leaf plate group in casing, the casing, casing top, bottom half is housed on water tank, and side lower part is communicated with water tank behind the gas and water separator, and the drip pan lower port is inserted in the water of water tank.

Deduster of the present utility model has that floor space is little, simple in structure, good dedusting effect, is easily promoted the good effect of using.

Fig. 1 is a structural representation of the present utility model.

Fig. 2, Fig. 3 are partial schematic diagrams.

Drawing explanation and embodiment are described below: 4 is water tanks by bracket supports among the figure, and the end of water tank 4 is the sediment awl buckets 5 that are arranged in order, and lower port that each awl struggles against is equipped with sediment butterfly valve 6 respectively.Be fixed with into mouth 1 in the front upper place of water tank, connect the floating barrier 2 that is supported with a strip being hinged with on the antetheca of water tank on 3, two keg floats of two keg floats; The top of baffle plate 2 is inserted in the fovea superior elongated slot of tank lid, and two keg floats 3 fluctuate with the height of water level, and baffle plate 2 also fluctuates thereupon, makes baffle plate 2 and horizontal plane keep certain ventilating opening.A water spray long tube 16 is housed on water tank, and water pump 9 supplies water in long tube 16, and the long mouth of water on long tube 16 ejects and form a water curtain, and the dust in the absorption flue gas falls into the water.On water tank 4, be equipped with by the gas-water separation page or leaf plate group (11,12,13) in casing 10, the casing, the gas and water separator that the outlet flue 14 on casing top, the drip pan of bottom half 15 are formed, side lower part is communicated with water tank 4 behind the gas and water separator, and drip pan 15 lower port are inserted in the water of water tank.In order to conserve water, below drip pan 5, can be provided with sedimentation basin 7, the water pump 8 in the sedimentation basin pumps into recirculated water in the water tank 4 through return pipe and reuses.This deduster, air-introduced machine produces very big negative pressure to outlet flue 14, the advance mouth 1 of the flue dust of boiler through tilting blows to the water surface and swashes the foam of breaking waves, big grain flue dust is sunk in first awl bucket 5 by suction, flue dust continues to move through the water bed passage of baffle plate 2 with horizontal plane, under the water curtain effect that water spray long tube 16 sprays, thin flue dust also absorbs for water, be deposited in the awl bucket 5 of back, flue gas continues to rise and enters in the gas and water separator, in stopping under the cooling of gas-water separation page or

leaf plate group

11,12,13, condensate moisture flows down on the page or leaf plate and along the inclined-plane and enters in the water tank 4.

Claims

1. impulse water bed circulation water curtain device for abatement of smoke and dust is characterized in that:

A., a water tank by bracket supports is arranged, and is the sediment awl bucket that is arranged in order at the bottom of the water tank, and the lower port of each awl bucket is equipped with the deslagging butterfly valve respectively;

B. be fixed with into mouth in the front upper place of water tank, on the antetheca of water tank, be hinged with two keg floats, connect the floating barrier that is supported with a strip on two keg floats, the water spray long tube is housed on tank lid;

C., the gas and water separator of being made up of the drip pan of the outlet flue on the gas-water separation page or leaf plate group in casing, the casing, casing top, bottom half is housed on water tank; The gas and water separator rear lateral portion is communicated with water tank; The drip pan lower port is inserted in the water of water tank.
