In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
The invention provides an asymmetric electrostatic enhancement electric bag coupling dust remover, which is an embedded electric bag composite dust remover and comprises an electric field area and a cloth bag area which are relatively independent. As shown in figures 1 and 2, the asymmetric electrostatic enhancement electrostatic bag coupling dust remover comprises an inlet flue 6, a shell 1, an ash bucket 5, a gas purifying chamber 7 and an outlet flue 8. The inlet flue 6 is arranged at the front end of the shell 1, when the flue gas enters the inlet flue 6, in order to achieve uniform gas distribution, the inlet flue 6 is arranged according to the bell mouth, and is internally provided with the uniform distribution plate 61, preferably, two layers of uniform distribution plates are arranged, and the inlet flue comprises a first uniform distribution plate and a second uniform distribution plate. In one embodiment, the first uniform distribution plate has an aperture ratio of 40% to 50% and the second uniform distribution plate has an aperture ratio of 30% to 45%.
The outlet flue 8 is arranged above the shell 1, a gas purifying chamber 7 is usually arranged above the shell 1, and the flue gas after electrostatic dust collection in the electric field area enters the cloth bag area, penetrates through the filter bag, is subjected to bag type dust collection, is converged to the gas purifying chamber from the central area of the filter bag, and is discharged out of the dust collector from the outlet flue. The ash hopper 5 is arranged at the bottom of the shell 1. The working mode of the bag-type area (bag-type dust remover) can be understood and imagined by a person skilled in the art, and is not described in detail herein.
At least two electric field channels 2 and a cloth bag area 3 are arranged in the shell, the electric field channels 2 are communicated with an inlet flue 6, and flue gas is uniformly distributed and shunted to each electric field channel through uniform distribution plates. The electric field channel comprises a non-porous anode plate 22, a folded anode plate 21, and a cathode wire frame 23 disposed intermediate the non-porous anode plate and the folded anode plate. The non-porous anode plate and the folded anode plate are arranged on two sides of the electric field channel in parallel. An asymmetric electric field is generated between the anode plate (comprising the non-porous anode plate and the folded anode plate) and the cathode wire frame. The cloth bag area is arranged between the two electric field channels, the folded anode plate is arranged on one side close to the cloth bag area and is arranged in a partition plate mode shared by the electric field channels and the cloth bag area. The folded anode plate is provided with a plurality of folded gaps which can communicate the electric field channel with the cloth bag area and are used as channels for smoke to enter the cloth bag area from the electric field channel (electric field area). The bag area is internally provided with a plurality of filter bags.
As shown in fig. 3, the folding nip includes a nip 211 and a folding flap 212 disposed on a surface of the nip. The opening of the folding baffle is obliquely arranged towards one side of the electric field channel, and the folding baffle and the folding anode plate are arranged in a straight-air acute angle manner, so that flue gas flow passes through the folding baffle from front to back in the electric field channel and then flows around to enter the cloth bag area through the folding gap, as shown in fig. 4. As a preferable technical scheme, the angle alpha between the folding baffle plate and the folding anode plate is 0< alpha < 30 degrees, and the width b of the folding baffle plate is more than or equal to the width of the gap, as shown in figure 5.
When the dust-containing flue gas to be dedusted flows through the electric field area, the dust in the flue gas is charged under the action of the electric field. On one hand, large particle dust in the flue gas is easily adsorbed on the surface layers of the non-porous anode plate and the folded anode plate, and most of dust load is removed. On the other hand, when the dust-containing smoke passes through the folding baffle, the smoke enters the cloth bag area through the folding gap in a streaming mode due to the action of inertia force, and large-particle dust which is not collected by an electric field is difficult to enter the cloth bag area in a reverse flow mode. The fine particle dust entering the cloth bag area along with the flue gas can form a loose and irregular filtering surface layer on the surface layer of the filter bag due to the same charge, so that the fine particle removal efficiency can be improved, the pressure loss of the filter bag can be reduced, and a better ventilation effect can be ensured.
In fact, the dust-containing flue gas can further form a vortex region through the folding baffle, thereby increasing the agglomeration and the residence time of the dust in an electric field region and being beneficial to high-efficiency dust removal. Meanwhile, the dust collecting area is not reduced by the folded anode plate, the shielding effect on the discharge sparks possibly generated by the cathode wire is achieved, and the firing problem of the cloth bag caused by the sparks is avoided.
The bottom of the cloth bag area is provided with a plurality of baffles, usually a group of 4 baffles, which are obliquely arranged in opposite directions to form a separation hopper. The separating hopper is positioned at the top of the ash hopper, and the mode of implementation which is often optimized is to arrange a plurality of separating hoppers. The arrangement of the separation hopper is mainly used for avoiding the short circuit of the flue gas caused by the flue gas entering the cloth bag area from the lower part of the electric field area. An ash discharge channel formed at the bottom of the separating hopper is communicated with the ash hopper, and a star-shaped ash discharger is arranged in the ash discharge channel, as shown in figure 6. Through the start-up of star ash discharger, can transfer the dirt that the sack district was collected to the ash bucket in, avoid the flue gas to go upward from here simultaneously. Another embodiment is as shown in fig. 7, a middle partition board is arranged in the ash discharging channel, the middle partition board selects an inverted V-shaped board, certain gaps are reserved on two sides of the inverted V-shaped board, when dust collected in a cloth bag area is accumulated to a certain degree, the dust can slide down into the ash bucket through the gaps under the action of gravity, meanwhile, the inverted V-shaped board greatly reduces the upward channel of air flow, the gap between the inverted V-shaped board and the ash discharging channel is blocked by the collected dust, and the upward channeling of flue gas is avoided.
Preferably, the front part of the cloth bag area is provided with a pre-dedusting area. As an optimized technical scheme, the folding anode plates at two sides of the pre-dust-removing area are provided with less or no folding seams, and the folding seams are intensively arranged in the area with the filter bag.
When the dust collector is provided with a plurality of cloth bag areas, correspondingly, the electric field channels are also increased, and the structure of one cloth bag area and two electric field channels is usually formed into a modular configuration. At this time, two electric field channels as described above are arranged between two adjacent cloth bag regions, that is, each electric field channel includes a non-porous anode plate, a folded anode plate, and a cathode wire frame arranged between the non-porous anode plate and the folded anode plate. And as mentioned above, the folded anode plate is arranged at one side close to the cloth bag area and is arranged in a partition mode shared by the electric field channel and the cloth bag area. Therefore, two adjacent electric field channels can be separated by a non-porous anode plate, and the electric field channel between two adjacent cloth bag regions can be called a double-electric-field channel.
An ash cleaning device is also arranged in the shell. The anode plate (comprising a non-porous anode plate and a folded anode plate) is provided with a dust cleaning device, preferably a mechanical rapping dust cleaning device. The filter bag is preferably a pulse ash removal device. The arrangement and operation of the ash removal device can be understood and envisioned by one of ordinary skill in the art and will not be described in detail herein.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
