Abstract
The invention discloses a multistage impact-type water-bath dedusting device. The device comprises a water tank containing water, at least two dedusting chambers with different grades are arranged above the water tank, the neighbored dedusting chambers are provided with a communicating gas pipe, the first-grade dedusting chamber is communicated to a flue gas inlet pipe, the gas outlet of the flue gas inlet pipe faces the water surface of the water tank; the gas outlet of the gas pipe faces the water surface of the water tank in the same grade dedusting chamber; and the last grade dedusting chamber is connected to a flue gas outlet pipe; wherein the gas inlet pipe and the gas pipe are both provided with a nozzle, which can spray water downwards. The multistage impact-type water-bath dedusting device has the advantages of good dedusting effect, high dedusting efficiency, and high flue gas purifying rate.
Description
Technical field
The present invention relates to cleaner technical field, especially a kind of multistage impulse type water bath dust arrester.
Background technology
In No. 201120123276.0 names of Chinese patent are called " a kind of impact-type water bath dust remover ", a kind of device for flue gas ash removal is disclosed at present, the dirt pocket of the water bath dust collector of this structure is single dirt pocket, and at the air inlet pipe place of dirt pocket, be not provided with the shower nozzle of water spray, therefore dust removing effects is not ideal enough, efficiency of dust collection is low, low to the purifying rate of flue gas.
Summary of the invention
The invention provides a kind of multistage impulse type water bath dust arrester, it is poor that it can solve existing single-stage water-bath type cleaner dust removing effects, and efficiency of dust collection is low, the problem low to the purifying rate of flue gas.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: include the water tank that is filled with water, above described water tank, be provided with at least two-stage dirt pocket, adjacent dirt pocket is provided with the tracheae of connection, wherein first order dirt pocket is communicated with the air inlet pipe of flue gas, and described air inlet pipe gas outlet is towards the water surface of described water tank; The gas outlet of described tracheae is towards the water surface of water tank in dirt pocket at the corresponding levels; Described final stage dirt pocket is communicated with flue gas escape pipe; At the shower nozzle that is provided with downward water spray of described air inlet pipe and tracheae.
In technique scheme, scheme is more specifically: described at least two-stage dirt pocket is to adopt baffle for separating to form in a casing.
Further: described flue gas escape pipe is top-down bending channel, and its exhanst gas outlet is positioned at the middle and lower part of flue gas escape pipe.
Further: the bending channel in described flue gas escape pipe comprises vertical water fender, horizontal water fender, and the interval between each water fender forms bending channel.
Further: the water adding in described water tank is alkaline water.
Owing to adopting technique scheme, the present invention compared with prior art, has following beneficial effect:
1, at least two-stage dirt pocket is set above water tank, adjacent dirt pocket is communicated with by escape pipe, and in dirt pockets at different levels and air inlet place sprinkler head is set, realize multistage three-dimensional impact type spraying and dedusting, utilize the suction-operated of water to be reduced in the dust concentration of occupying suitable proportion in flue gas, efficiency of dust collection is high, effective, does not produce secondary pollution.
2, simple in structure, cost is low, it is little to invest, easy for installation, the water reusable edible in water tank, save the energy, operating cost is low, wide accommodation is easy to promote the use of, and adds alkaline water in water tank, can play desulfidation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing example, the invention will be further described:
The present embodiment as shown in Figure 1, it includes air inlet pipe 1, shower nozzle 2, escape pipe 3, dividing plate 4, vertical water fender 5-1, horizontal water fender 5-2, flue gas escape pipe 6, spray pump 7, water tank 8, dirt pocket 9-1, dirt pocket 9-2.
In water tank 8, be loaded with alkaline water, flue gas can also play the effect of desulfurization in dedusting.Above water tank 8, there is a casing to adopt the dividing plate 4 of longitudinally installing to be separated into two-stage dirt pocket 9-1, 9-2, the top of first order dirt pocket 9-1 is communicated with smoke inlet pipe 1, bottom is stretched in the water of water tank 8, the gas outlet of air inlet pipe 1 is towards the water surface of described water tank 8, make dedusting indoor humidity very large, be conducive to grit sedimentation, the top of second level dirt pocket 9-2 is communicated with first order dirt pocket by escape pipe 3, the gas outlet of escape pipe 3 is towards the water surface of water tank 8, second level dirt pocket 9-2 is communicated with flue gas escape pipe 6 as final stage dirt pocket, flue gas escape pipe 6 is top-down bending channel, its exhanst gas outlet is positioned at the middle and lower part of flue gas escape pipe 6, bending channel in flue gas escape pipe 6 comprises vertical water fender 5-1, laterally water fender 5-2, interval between each water fender forms bending channel, when the flue gas that carries water smoke is during through bending outlet passageway, two water fenders can stop water smoke it is fallen in water tank.Air inlet pipe 1 and escape pipe 3 are provided with sprinkler head 2, and shower nozzle 2 is communicated with spray pump 7.
The course of work of this device is: from boiler, flue gas out enters from the air inlet pipe 1 of device, sprinkler head 2 is housed in air inlet pipe 1, ash material in the water smoke of shower nozzle 2 places ejections can moistening flue gas, in this process, ash material is made its weight increasing and is conducive to separated by water smoke is moistening.After this with the quite high velocity shock water surface, wherein most of grit is stayed in water because weight strengthens or sticks back with water, this stage is assault phase, after this stage produces, the water surface forms parabola shaped water droplet, water smoke and a foam regions because of the motion of gas, dusty gas in this region again further water droplet water smoke purify.This is the trickle bath stage.During again because of access to plant, the temperature of flue gas is generally not less than 80 degree, and (what have is higher) forms water smoke in dirt pocket under the impact of flue gas, and grit, changing direction, while moving upward, is further purified by water smoke again, and this stage is nebulization dust.After purifying by above three kinds of modes, clean gas flows out from first order dirt pocket escape pipe 3, enters into second level dirt pocket and again carries out dedusting, thereby realize multistage dedusting.
