Description

Ceramic multi-tube desulfurate dust remover

The utility model relates to a kind of device of removing the solid combustion product, and particularly the centrifugal force that produces by the liquid hydro-peening and the process of curling up by air-flow separates the deduster of dispersed granules and removal sulfur dioxide from gas.

Existing ceramic multicyclone dust collector is to remove dust in flue gas by the centrifugal force that the air-flow process of curling up produces.This centrifugal particulate floating dust and the sulfur dioxide that can not remove in the flue gas that divided, dust removing effects is not good, and discharged flue gas still contains higher oxious component, contaminated environment and influence the healthy of people, compliance with environmental protection requirements fully.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of high-efficiency ceramic multitube desulfurizing dust-collector that has dedusting and two kinds of functions of desulfurization concurrently is provided.

Technical solution of the present utility model is: ceramic multitube desulfurizing dust-collector comprises housing, by blast pipe, guider, the molecular movement of whirlwind, inlet plenum, exhaust chamber, ash bucket, its special character is that it also has the spray equipment of being made up of shower nozzle and water system, its shower nozzle can be located at the deduster air inlet pipe or/and in the inlet plenum, and evenly distributes at regular intervals or enrank.Shower nozzle is preferably disposed in the air inlet pipe and is in line, so that the flue gas that enters in the deduster is evenly washed.If give the large-tonnage boiler supporting, also can in inlet plenum, set up a few row's shower nozzles, fully wash flue dust.Spray equipment is set in deduster, not only can removes sulfur in smoke, can also increase the weight of dust, and then increase centrifugal force, be easier to remove dust, make the particulate floating dust that is difficult to administer obtain handling, further improve efficiency of dust collection, also reduced the temperature in the deduster simultaneously.In the water tank of liquid below movement flows into ash bucket, the flue dust that sticks on the dust-removing element is washed away.

The air inlet pipe of deduster is obliquely installed, and promptly forms certain acute angle with deduster casing vertical direction, flows backward to flue to prevent the liquid in the air inlet pipe, also makes flue gas directly pour guider simultaneously, can reduce resistance, increases the rotary speed of flue gas.In exhaust chamber, be provided with moisture separator or/and dewatering plate.At dust collector ash hopper, being provided with below can be with liquid, dirt separating and filtering device.

Characteristics of the present utility model are: set up spray equipment in existing ceramic multicyclone dust collector, make this deduster not only can dedusting, but desulfurization again, also the particulate floating dust can be got rid of, improved efficiency of dust collection greatly, reduced pollution, the liquid that flows in the deduster can also reduce interior temperature of deduster and the flue dust that washes away on the dust-removing element, and can prevent flue gas corrosion, prolonged the service life of deduster.This deduster is simple and reasonable for structure, need not increase floor space, and cost is low, convenient operation and management.

Be described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, to provide a kind of be 0.5 ton of deduster that boiler is supporting to present embodiment.Its housing (9) adopts metal also can adopt nonmetallic materials to make obturator.Lower housing portion is connected with the ash bucket (5) of band lock (4) and is used for the support (3) of support housing.Box bottom (6) is provided with ash-hole, be provided with the movement (10) that constitutes by whirlwind, guider and blast pipe with the corresponding base plate in this hole, on base plate, also be provided with the fixing following seal (7) of whirlwind, simultaneously also with ash bucket and housing isolating seal.Be filled with resistant to elevated temperatures filler (8) between whirlwind, whirlwind and guider junction armored concrete fixing seal, guider and blast pipe sealing and fixing, be provided with the mounting plate with holes (12) that is connected on the housing on blast pipe top, the position in its hole is corresponding with blast pipe, and make blast pipe pass mounting plate, and on mounting plate, also being provided with one deck sealant (13), it is fixed blast pipe and housing is divided into inlet plenum (17) and exhaust chamber (18).Be provided with upper and lower two-layer moisture separator that links to each other with housing (14) and dewatering plate (15) in exhaust chamber, moisture separator is made of helical blade.Dewatering plate is the dense micropore plate, and gas outlet (16) are located at case top.Be provided with the air inlet pipe (1) that communicates with it on a sidewall of inlet plenum housing, the angle of it and casing vertical direction is 60 degree.Be provided with row's spout shower nozzle (2) down in air inlet pipe, see Fig. 2, the water inlet pipe of shower nozzle (11) is connected with the water system (see figure 3).Water system is made of water pump (19), water tank (20) and tube connector, and the liquid in the water tank is akaline liquid.The spout of shower nozzle is a flat, so that the water of ejection forms one deck cascade.

Be provided with filter (22) on the Storage water tank below ash bucket (21), it constitutes plate filter unit by two-layer bar-mat reinforcement and the foamed plastics that is positioned at the iron net, its periphery is provided with a grade limit, the dirt liquid that flows out from flapper filters through filter, liquid flows into use to be recycled in the Storage water tank, and dust then is piled up in to be waited on the filter to remove.

In the time of in ash-laden gas enters deduster, at first spray through akaline liquid, generate nontoxic calcium sulfide precipitation after making sulfur in smoke meet alkali lye, make dust moistening simultaneously, gain in weight, rotatablely move from top to bottom and reach the bottom of whirlwind gradually through the spiral mouth of guider outer tube then.Dust in flue gas is constantly mixed with the liquid collision in this process, makes it constantly be thrown to tube wall, and falls in the ash bucket along wall.Liquid also will flow in the ash bucket.After downward flue gas arrives the sub-cone base of whirlwind, will transfer upwards to form the inside vortex that rises, after the guider blast pipe enters exhaust chamber, discharge from the deduster gas outlet through moisture separator and dewatering plate again along the movement axis part.
