Description
Technical field
The present invention relates to a kind of cleaner technical field for smoke gas treatment, relate to specifically a kind of superposing type electric-bag complex dust collector.
Background technology
Existing a kind of electric-bag complex dust collector, its front portion is that electric dust removing system, rear portion are filter bag dust pelletizing system.Between electric dust removing system and filter bag dust pelletizing system, be provided with choke apparatus, the Main Function of this choke apparatus is the air-flow that electric dust removing system is flowed out, and enters in it, carry out dedusting from filter bag dust pelletizing system below.Because said structure can cause the bottom wind speed of electric dust removing system too high, thereby the efficiency of dust collection of electric dust removing system is declined.While, local filter bag was subject to washing away of high velocity air, easily produces broken bag, has therefore shortened the service life of filter bag because the flue gas flow of the front and rear portions of filter bag dust pelletizing system is inhomogeneous.In addition, for large-scale deduster, positive plate can be accomplished the height of 16 meters, can only reach 8 meters and filter bag is the longest, if adopt existing electricity bag composite construction, floor space is larger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of superposing type electric-bag complex dust collector, and not only efficiency of dust collection is high for this superposing type electric-bag complex dust collector, and life of bag filter is long, and floor space is little.
For solving the problems of the technologies described above, a kind of superposing type electric-bag complex dust collector of the present invention, contain casing, ash bucket, electric dust removing system and filter bag dust pelletizing system, ash bucket is arranged on the lower end of casing, the internal upper part of casing is provided with air-purifying chamber, the bottom of this air-purifying chamber is card, electric dust removing system and filter bag dust pelletizing system are positioned at casing, filter bag dust pelletizing system is arranged on card, casing contains air inlet and air outlet, electric dust removing system comprises cathode frame, insulating suspension, negative electrode row and anode row, filter bag dust pelletizing system comprises the filter bag dust removing units being made up of several filter bags, described electric dust removing system is positioned at the below of filter bag dust pelletizing system, the insulating suspension of described electric dust removing system is arranged in described air-purifying chamber, the cathode frame of described electric dust removing system is through the space at filter bag dust pelletizing system place, and be connected with the insulating suspension that is positioned at air-purifying chamber, the air inlet of described casing is positioned at the bottom of casing front end face, the air outlet of described casing is positioned on the rear end face of described air-purifying chamber.
The both sides of the filter bag dust removing units in described filter bag dust pelletizing system are provided with deep bead.
The described bottom that is arranged on the insulating suspension in air-purifying chamber is provided with dust proof tube, and the upper end of this dust proof tube is connected with the sealed bottom of insulating suspension, and the lower end of this dust proof tube is fixedly connected with described air-purifying chamber bottom card.
Center line between the anode row of described electric dust removing system and adjacent negative electrode row, with the filter bag centerline in described filter bag dust pelletizing system in same plane.
Distance between the anode row of described electric dust removing system and adjacent negative electrode row, and distance between adjacent filter bag in described filter bag dust pelletizing system equates, this distance is 160mm-300mm.
Above-mentioned superposing type electric-bag complex dust collector, because electricity is positioned at the space of filter bag of dust collector dust pelletizing system bottom except dust pelletizing system, therefore floor space is little.Be positioned at the bottom of casing front end face due to air inlet simultaneously, air outlet is positioned on the rear end face of described air-purifying chamber, therefore first ash-laden gas enters electric dust removing system from air inlet and carries out dedusting, gas after electric precipitation enters in the filter bag dust pelletizing system in upper space again and carries out dedusting, thereby not only overcome the deficiency that prior art adopts choke apparatus to cause wind speed efficiency of dust collection too high and that cause in electric dust removing system bottom to decline, and overcome prior art filter bag dust pelletizing system before, the flue gas flow at rear portion is inhomogeneous, local filter bag is subject to high velocity air and washes away the generation of easy generation broken bag phenomenon.
