Description

Technical Field

[0001] This utility model relates to the field of dust collector bag technology, specifically to a fluoropolymer dust collector bag for waste incineration. Background Technology

[0002] During waste incineration, a large amount of smoke and harmful gases are generated. If these smoke and gases are released directly into the atmosphere without effective treatment, they will cause serious harm to the environment and human health. Therefore, dust collection equipment is an essential and critical component in waste incineration systems. While traditional dust collector bags can filter out some smoke to a certain extent, they often suffer from low filtration efficiency, short service life, and easy clogging when dealing with the high-temperature, high-humidity, and highly corrosive smoke from waste incineration. Therefore, developing a high-efficiency, high-temperature resistant, and corrosion-resistant dust collector bag for waste incineration is of great significance. Utility Model Content

[0003] The purpose of this invention is to provide a fluoropolymer dust collector bag for waste incineration treatment, so as to solve the problems mentioned in the background art.

[0007] As a further improvement of this utility model, the height distance between the top and bottom of the plurality of support columns is less than the height distance between the top and bottom of the dust collection bag.

[0008] As a further improvement of this utility model: the bottom of the dust collection bag is fixedly connected to a bottom connecting ring, and the inner diameter of the bottom connecting ring matches the outer diameter of the bottom ring.

[0009] As a further embodiment of this utility model: the outer wall of the bottom connecting ring and the connecting threaded hole are threadedly connected to a plurality of connecting bolts, and the plurality of connecting bolts are threadedly connected to the connecting threaded hole that is matched in position, passing through one end of the bottom connecting ring.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: By employing a fluoropolymer filter layer combined with a needle-punched felt coating and a high-temperature resistant coating, the filtration efficiency of the dust collector bag can be significantly improved, effectively capturing fine smoke and harmful gases generated during waste incineration.

[0022] Please see Figures 1-6 In this embodiment of the utility model, the fluoropolymer dust collector bag for waste incineration includes the following components:

[0023] Connecting pipe 1: Located at the bottom of the dust collector bag, it is used to connect to the flue gas emission port of the waste incineration system. A connecting flange 2 is fixedly connected to the outer wall of the bottom end of connecting pipe 1, which facilitates bolt connection with the emission port flange and ensures that the flue gas can be smoothly introduced into the dust collector bag.

[0024] Smoke hopper 3: Fixedly connected to the top of connecting pipe 1, used to collect and guide smoke and dust into the dust collector bag. The design of smoke hopper 3 helps to distribute smoke and dust evenly and improves dust removal efficiency.

[0025] Dust collector bag 5: Located at the top of the smoke collection hopper 3, it is the core component of the dust collector bag. The outer wall of the dust collector bag is a base fabric 57, and the inner wall is sequentially fixed with a fluoropolymer filter layer 56, a needle-punched felt coating 55, and a high-temperature resistant coating 54. This layered arrangement can significantly improve the filtration efficiency and service life of the dust collector bag.

[0026] Filter groove 53: The inner wall of the dust bag 5 is provided with a filter groove 53 that extends to the bottom, which helps the smoke and dust to pass through and be filtered.

[0027] Dust trough 10: The inner walls of the smoke hopper 3 and the connecting pipe 1 are connected by a dust trough 10, the inner and outer diameters of which are matched with the inner and outer diameters of the filter tank 53, to ensure that the dust can smoothly enter the dust collector bag for filtration.

[0028] Support structure: including top connecting ring 4, bottom ring 6, support column 7, reinforcing ring 9, etc. These structures enhance the overall stability of the dust collector bag and prevent it from deforming or breaking under high pressure and high temperature environments.

[0029] Connection device: The bottom of the dust collector bag 5 is connected to the bottom ring 6 through the bottom connecting ring 51, and is fastened by the connecting bolt 52 and the connecting threaded hole 61 to ensure the stable installation and convenient disassembly of the dust collector bag.

[0030] The working principle of this utility model is as follows:

[0031] When the flue gas generated by the waste incineration system enters the dust collector bag through the connecting pipe 1 and the flue gas hopper 3, the flue gas first enters the flue gas trough 10 and then enters the dust collector bag 5 along the filter groove 53.

[0032] When smoke and dust pass through the fluoropolymer filter layer 56 of the dust collector bag 5, fine dust and harmful gases are effectively captured, while clean gases are discharged through the filter layer. The fluoropolymer filter layer 56 has excellent filtration performance and corrosion resistance, and can withstand high temperature, high humidity and highly corrosive waste incineration smoke and dust.

[0033] The high-temperature resistant coating 54 enables the dust collector bag to withstand the high-temperature gases generated during waste incineration, extending the service life of the bag.

[0034] The structural design of the support column 7 and the reinforcing ring 9 enhances the overall structural stability of the dust collector bag, improves its resistance to deformation and pressure, and ensures that the dust collector bag maintains excellent filtration performance during long-term use.
