dust and sulfide.One section below the trunnion is increaser, and its caliber from top to bottom enlarges gradually.Make the fluid velocity that enters this pipe reduce gradually, be beneficial to the sedimentation of flue dust.The base places one section of the bottom of water-bath to be effuser, and it is toroidal to increase the contact-making surface of fluid and following water-bath, makes the gas of sulfur-bearing and flue dust contact major part with alkaline water and is left in the water-bath.Be preferably in the position that effuser is positioned on the water surface and be provided with through hole, so that when shutting down, do not make deduster internal memory cigarette.Inner surface at effuser is provided with spiral yarn shaped fin, to increase the contact of gas-liquid.Position on housing above the Venturi scrubber base is provided with the spout hole that keeps the water-bath water level.Be provided with on the anchor ring on water-bath between Venturi scrubber and the housing on the supporting member that the inner is located at Venturi scrubber outside, the outer end is located at the water screen that is made of a plurality of water fenders on the housing inner support, its two adjacent water fenders partly overlap but are at regular intervals, and they not only can cover ring surface with the row waterborne in the prevention water-bath but also do not influence passing through of gas.Preferably water fender is a kind of curved slab that reduces water to its impulsive force.Be provided with on water fender screen that the inner is located at the Venturi scrubber outside, the outer end is located at the filter in the housing.It is that be provided with between wire netting can be by the nonmetallic materials of gas, as fiber, asbestos etc., to remove showy micronic dust.Preferably the cross section of filter is spill, can increase the rectangle mudhole of bottom for tilting of contact-making surface, conical shell like this, and it and blowdown machine casing are complementary and are fixed thereon.Blowdown machine mainly includes casing, driving shaft, driven pulley, sprocket wheel, chain, scraper plate and dust discharge passage.The cross section is that the blowdown machine casing of rectangle is obliquely installed, and low order end sealing high order end opening surpasses the height of deduster overfall.The deduster sewage draining exit links to each other with opening on the low level one side box body end face.On the casing of a high-order side, be provided with the driving shaft that links to each other with motor.This trunnion axis passes casing biside plate two ends and is positioned on the outer bearing of casing, also is provided with driven shaft at low level and other position of casing in addition, and these trunnion axis also pass casing biside plate two ends and are positioned on the outer bearing of casing.Establish a sprocket wheel on the every axle, be provided with the chain of forming by carrier bar that is complementary with it in the outside of sprocket wheel again.The carrier bar outside every a segment distance on chain is provided with a scraper plate, it can sweep the mud shape flue dust that deduster is discharged along with the motion of chain is taken it water surface of casing out of from bottom half, release from the casing upper end open then, drop down onto in the flute profile passage that is connected with casing.The passage lower end of this inclination places on the boiler slag remover.Mix the secondary pollution of not only having saved the water that sprays to slag but also solved the wet type slag remover with caustic slag from the acid mud shape flue dust that flows down.Water tank partly includes: water tank, shower nozzle and pipeline.Wherein water tank is the trough-shaped housing that opening is arranged on two, and a groove is for containing the alkali groove of lime, and another is a tank.Vertical clapboard top is provided with spout hole between two grooves.On two grooves of water tank, respectively establish a upper hose again.Bottom at tank is provided with drainpipe, and the
