Abstract
The utility model relates to an improved bag filter, which comprises a case body, a bag house, an air-purifying chamber, ash buckets and a bag filter, wherein the case body is provided with an air inlet and an air outlet; the bag house and the air-purifying chamber are formed inside the case body; the ash buckets are arranged at the lower part of the case body; the bag filter comprises a pulse dust cleaning system; anode wires 4 with a network structure are vertically arranged on both sides of each row of filtering bags 5 in the bag house; and cathode wires 3 are vertically arranged between the anode wires with a network structure for the adjacent filtering bags. Dust in flue gas is charged between the cathode wires and the anode wires with a network structure at first, and then the charged dust moves towards the anode wires with a network structure and the filtering bags under the action of electric field force; most of the dust is absorbed on the outer surfaces of the filtering bags through meshes of the anode wires; attractive force and repulsive force exist among the dust on the surfaces of the filtering bags since the dust is charged; moreover, the structure of a formed dust layer is looser, and the voidage is higher, so that the passing of clean gas is facilitated, the operation resistance force of equipment can be reduced greatly, and the dust cleaning time of the filtering bags is prolonged, i.e. the service life of the filtering bags is prolonged.
Description
Technical field
The utility model relates to a kind of improved dust-precipitator.
Background technology
Filter bag is the critical component in the bag collector, the dust-collecting efficiency and the equipment running resistance of decision bag collector.Simultaneously filter bag also be change in the bag collector the most frequent, cost maximum parts, account for more than 85% of bag collector maintenance cost.In use, when dust runs up to certain thickness on filter bag, just must deashing.Deashing frequency height, life of bag filter is short.The deashing frequency is low, and equipment resistance is big.The cottrell dust-collecting efficiency is relevant with field area, and field area is big, the dust-collecting efficiency height, but equipment investment and operating cost all sharply increase.Occupation area of equipment is also big simultaneously, is difficult on the technology arranging.
Summary of the invention
The purpose of this utility model is to provide a kind of operating cost low, the improved bag collector that dust-collecting efficiency is high.
Its technical scheme is: a kind of improved bag collector, comprise by the casing that is provided with into and out of the air port, be arranged on bag chamber and air-purifying chamber in the casing, be arranged on the ash bucket of lower box and the bag collector that the pulse dust cleaning system forms, it is characterized in that: the both sides of the indoor every row's filter bag of described bag vertically are provided with respectively by hanger bar and are suspended on cancellated anode line on the card, vertically are provided with respectively between the cancellated anode line of adjacent filter bag by porcelain insulator and are suspended on cathode line on the card.
The bottom of above-mentioned box side is respectively equipped with anode ash removal equipment for flapping and cathode rapping deashing device.
Its beneficial effect is: flue gas enters dust arrester installation from air inlet, dust in flue gas is at first charged between cathode line and cancellated anode line, dust after charged moves to cancellated anode line and filter bag direction under the effect of electric field force, fraction is attracted on the cancellated anode line, major part is attracted to the filter bag outer surface by the anode line mesh, because dust is charged, so existing gravitation has repulsion again between the dust on filter bag surface, formed dust layer structure is more open, voidage is than higher, thereby helping clean gas passes through, greatly reduce the running resistance of equipment, prolong the filter bag ash removal time, just prolonged the service life of filter bag; Simultaneously, be provided with cancellated anode line between filter bag and the cathode line and isolate, avoided filter bag to burn because of arcing; In addition, adopt cancellated anode line, also help air-flow and evenly pass through, the fritter that breaks when inverted draft does not freely cause the filter bag dust layer to peel off when having avoided filter bag ash removal is too much, the problem that the secondary ceiling is too much.Compare with the dust-precipitator of equal dust-collecting efficiency, dust-precipitator volume of the present utility model is less relatively, and equipment investment and operating cost also all decline to a great extent.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 vertical view.
The specific embodiment
As shown in Figure 1, 2, improved bag collector comprises by the casing that is provided with into and out of the air port, is arranged on bag chamber and air-purifying chamber in the casing, is arranged on the ash bucket of lower box and the bag collector that the pulse dust cleaning system forms.The both sides of the indoor every row's filter bag 5 of bag vertically are provided with respectively by porcelain insulator and are suspended on cancellated anode line 4 on the card, vertically are provided with respectively between the cancellated anode line of adjacent filter bag by porcelain insulator and are suspended on cathode line 3 on the card.
The bottom of above-mentioned box side is respectively equipped with anode ash removal equipment for flapping 41 and cathode rapping deashing device 31.
Be provided with three layers of mesh plate 2 that plays equal wind guide functions in the air inlet 1.
Its course of work: flue gas enters dust arrester installation behind air inlet 1 process three-layer network orifice plate 2, dust in flue gas is in cathode line 3, charged between the cancellated anode line 4, dust after charged moves to cancellated anode line and filter bag 5 directions under the effect of electric field force, fraction is attracted on the cancellated anode line, major part is attracted to the filter bag outer surface by the anode line mesh, because dust is charged, existing gravitation has repulsion again between the dust on filter bag surface so be attracted to, formed dust layer structure is more open, voidage helps clean gas and passes through than higher.When dust layer ran up to certain thickness, the starting impulse soot cleaning system carried out deashing to filter bag, and under air blast blowback and vibrations, dust layer breaks away from the filter bag outer surface, and major part falls into ash bucket, and a part is by the filter bag second adsorption, and a minimum part is adsorbed by anode line.Regularly rapping of anode line, the dust layer that adheres on anode line part major part falls into ash bucket, and a part is adsorbed by filter bag, and a minimum part is by cancellated anode line second adsorption.Regularly rapping of cathode line, the dust layer that adheres on cathode line part major part falls into ash bucket, and a part enters in the air-flow polar curve and the motion of filter bag direction on the sunny side of charged back and is adsorbed.Clean gas permeation filter bag enters the air-purifying chamber 6 of filter bag top, is extracted out by blower fan by air outlet 7.
