Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, and more specifically to an anti-corrosion bag dust removal device. Background Art

[0002] The smoke generated by incineration, the products of the neutralization reaction of acidic gases, and the lime dust that did not participate in the reaction form solid particles in the flue gas. The equipment for removing solid particles in the flue gas is a bag dust removal device;

[0003] The bag filter has a very high dust removal efficiency, which can reach 99.9% or even higher. In particular, it can effectively capture submicron particles. This feature is very beneficial for the removal of heavy metal aerosol particles. In addition, it is more effective in removing dioxins. In the deacidification tower, trace dioxin particles in the flue gas are adsorbed by tiny lime particles. In addition, activated carbon is added before the bag filter to adsorb dioxins, heavy metals and other substances in the flue gas. In the bag filter, dioxins adsorbed on submicron particles are captured. Most of the dioxins exist in solid particles, which largely controls the emission of dioxins and dust.

[0004] The existing bag dust removal device, because the acidic substances in the material such as S, Cl, F, etc. are easy to produce acidic gases such as SO2, SO3, Hcl, HF after incineration, if the air leakage coefficient of the flue and the bag top plate is large, the acidic high-temperature gas is easy to condense and dew point corrosion after encountering cold air, causing irreversible corrosion to the top of the bag upper box, the orifice plate, etc., and the conventional bag dust removal device The top cover of the upper box is not insulated and sealed, and the air leakage is large; and the injection pipe and the cover valve are an integrated structure, and the injection pipe cannot be replaced separately after corrosion. In view of this, we propose an anti-corrosion bag dust removal device. Utility Model Content

[0025] An anti-corrosion bag dust removal device includes a box body 100, a side wall of the box body 100 is provided with a smoke inlet 110, and the other side wall of the box body 100 is provided with a smoke outlet 120. The smoke enters the box body 100 from the smoke inlet 110 for filtration and is discharged from the smoke outlet 120. A plurality of blowing pipes 200 are provided on the upper part of the box body 100. The blowing pipes 200 include valves 230 and pipes 210. The circumferential side wall of the pipe 210 is provided with a plurality of nozzles 220. The function of the blowing pipes 200 is to transport high-pressure gas to the inside of the box body 100, clean the dust accumulated on the bag inside the box body 100, reduce the clogging of the bag, and improve the operation efficiency of the bag dust collector. Through the joint action of the plurality of blowing pipes 200, , which not only makes the bag air permeable and maintains a good working condition, but also facilitates replacement and maintenance when a certain blowing pipe 200 fails. A plurality of sealing cover plates 300 are arranged on the top surface of the box body 100, and two jackets 310 are connected to the side walls of the sealing cover plates 300. Insulating rock wool 320 is arranged between the two jackets 310, and the insulating rock wool 320 is clamped by the two jackets 310. The insulating rock wool 320 is a commonly used insulating material with excellent insulating performance, high temperature resistance, good fire resistance and chemical stability, which makes it not easy to be corroded, and protects the top cover plate from being easily corroded. A tongue-and-groove groove 330 is arranged at the bottom of the sealing cover plate 300, and the tongue-and-groove groove 330 is used to reduce the air leakage rate.

[0026] Specifically, in order to achieve a good dust removal effect inside the box 100, a plurality of filter bags are arranged inside the box 100. The filter bags are made of woven filter cloth, and the filter bags are the prior art in the example.

[0027] Furthermore, in order to control the operation of the blowing pipe 200, one end of the valve 230 is connected to the pipeline 210, and the other end is connected to the external high-pressure gas pipeline, and the valve 230 controls the switch of the high-pressure gas.

[0028] It is worth noting that in order to ensure better connectivity of the tongue-and-groove groove 330 , a flange plate, bolts and gaskets are provided in the tongue-and-groove groove 330 . The bolts penetrate the top of the sealing cover plate 300 , and cooperate with the flange plate and gasket to fix the sealing cover plate 300 to the top of the box body 100 .

[0029] In addition, in order to facilitate the lifting of the sealing cover plate 300 when disassembling the sealing cover plate 300 , a handle 340 is welded on the top surface of the sealing cover plate 300 , and the handle 340 is made of stainless steel.

[0030] Working principle: When the device is required to produce an effect, the smoke enters the interior of the box 100 from the smoke inlet 110 for filtration and is discharged from the smoke outlet 120. Solid particles or dust in the smoke remain on the cloth bag inside the box 100. The switch of the high-pressure gas is controlled by the valve 230, so that the high-pressure gas is sprayed from the multiple nozzles 220 of the pipeline 210 to blow the cloth bag in the box 100, so that the fixed particles or dust on the cloth bag are cleaned, the air permeability of the cloth bag is maintained, and the cloth bag has good use function. On the other hand, during the process of the spray pipe 200 spraying the interior of the box 100, the fixed particles or dust float around inside and overflow outward at the joint between the sealing cover plate 300 and the box 100. The designed tongue-and-groove groove 300 is used to fix and seal the sealing cover plate 300 and the box 100, so that the fixed particles or dust are difficult to overflow.
