[0002] In the field of metal smelting, with the continuous expansion of industrial scale and constant innovation in production processes, metal output has steadily increased, providing a solid material foundation for various sectors of the national economy. However, this development process is also accompanied by severe environmental challenges. Metal smelting generates large amounts of complex flue gas, which contains not only various dust particles but also harmful pollutants such as sulfur dioxide, nitrogen oxides, and heavy metals.

[0003] Traditional filtration equipment struggles to meet current stringent environmental standards when dealing with high-temperature, high-concentration, and complex metal smelting fumes, resulting in inadequate removal of fine dust and harmful gases. Furthermore, the excessively high flue gas temperature easily damages filter materials, shortening equipment lifespan. Frequent component replacements not only increase operating costs but also disrupt production continuity and stability. In addition, existing dust removal methods are often ineffective and require significant manpower for maintenance, further exacerbating the burden on businesses. Utility Model Content

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a metal smelting flue gas treatment structure, including,

[0027] The collection component 100 includes a bracket 101, a box 102 fixedly connected to the top of the bracket 101, a sealing plate 103 fixedly connected to the top of the box 102, and an air supply pipe 104 encapsulated on the side wall of the box 102, the air supply pipe 104 communicating with the inside of the box 102.

[0028] The filter assembly 200 includes a partition 201 that is sealed and inserted inside the housing 102, a filter cartridge 202 that is sealed and inserted in the middle of the partition 201, a filter bag 203 that is fixedly sleeved on the side wall of the filter cartridge 202, and a guide plate 204 that is fixedly connected to the side wall of the partition 201. The guide plate 204 is sleeved on the end of the air supply pipe 104, and the bottom outlet of the guide plate 204 extends to below the filter bag 203.

[0029] The bracket 101 provides a stable mounting platform for other components. The housing 102 houses and processes flue gas. The sealing plate 103 seals the housing 102 to prevent flue gas leakage. The gas supply pipe 104 is encapsulated on the side wall of the housing 102 and communicates with the interior of the housing 102. Its function is to introduce the flue gas generated by metal smelting into the housing 102 for treatment. The partition 201 is sealed and inserted into the interior of the housing 102, dividing the interior of the housing 102 into different areas, which helps guide the flow path of the flue gas. The filter bag 203 is fixedly sleeved on the side wall of the filter cartridge 202 to ensure the flue gas filtration effect. The guide plate 204 guides the flue gas entering from the gas supply pipe 104 to the area below the filter bag 203, so that the flue gas can pass evenly through the filter bag 203 and the filter cartridge 202 for filtration.

[0030] Specifically, the filter assembly 200 also includes a heat-conducting plate 205 fixedly connected to the lower side wall of the housing 102, and a cover plate 206 inserted into the outside of the heat-conducting plate 205. The end of the heat-conducting plate 205 extends to the bottom of the guide plate 204. The side wall of the cover plate 206 is bolted to the outer side wall of the housing 102. The filter assembly 200 also includes a liquid supply pipe 207 sealed and installed on the side wall of the cover plate 206. The liquid supply pipe 207 is inserted into the middle of the through hole at the end of the heat-conducting plate 205, and the lower end of the liquid supply pipe 207 is fixedly connected to the side wall of the bracket 101.

[0031] The liquid supply pipe 207 can deliver coolant to the heat conduction plate 205 to remove the heat absorbed by the heat conduction plate 205 and play a role in cooling. The cover plate 206 plays a role in protecting and sealing the heat conduction plate 205.

[0032] Furthermore, the filter assembly 200 also includes a pulse tube 208 that is sealed and inserted into the top side wall of the housing 102, and a pulse valve 209 that is fixedly connected to the end of the pulse tube 208. The end of the pulse tube 208 extends above the partition 201, and the air outlet on the side wall of the pulse tube 208 is used in conjunction with the filter cartridge 202.

[0033] The pulse valve 209 is fixedly connected to the end of the pulse tube 208 and is used to control the generation of pulse airflow. When the pulse valve is open, the pulse airflow enters the filter cartridge 202 through the pulse tube 208 to clean the filter cartridge and filter bag.

[0034] Furthermore, the filter assembly 200 also includes a connecting rod 210 that is movably inserted into the housing 102, and a lever 211 that is fixedly connected to the side wall of the connecting rod 210, with the end of the lever 211 being engaged with the side wall of the filter cartridge 202.

[0035] The linkage 210 can be operated to drive the lever 211 to shake the filter cartridge 202, which helps to clean the dust.

[0036] Preferably, the collection assembly 100 also includes a maintenance plate 105 that is sealed and inserted into the side wall of the housing 102, the end of which is connected to the side wall of the housing 102 by a handle bolt.

[0037] The inspection plate 105 is sealed and inserted into the side wall of the enclosure 102, and is connected to the side wall of the enclosure 102 by a handle bolt, which makes it convenient for staff to open the enclosure for internal inspection and maintenance.

[0038] Preferably, the collection assembly 100 further includes a collection box 106 inserted into the bottom of the box body 102. The end sidewall of the collection box 106 is connected to the bottom sidewall of the box body 102 by a latch, and the bottom of the collection box 106 is fitted with rollers.

[0039] The collection box 106 is used to collect dust and other impurities separated during the processing, and the roller design makes it easy to move and clean the collection box.

[0040] In operation, the high-temperature flue gas generated during metal smelting enters the housing 102 through the gas supply pipe 104. Guided by the guide plate 204, the flue gas is directed below the filter bag 203. At this time, the heat-conducting plate 205 absorbs some of the heat from the flue gas, while the liquid supply pipe 207 delivers coolant to the heat-conducting plate 205, carrying away the heat absorbed by the heat-conducting plate and performing preliminary cooling of the flue gas. The flue gas flows upward, passing sequentially through the filter bag 203 and the filter cartridge 202. The filter bag and filter cartridge filter dust, particulate matter, and other impurities in the flue gas, intercepting them on their surfaces, allowing the purified flue gas to continue flowing upward.

[0041] When dust accumulates on the surfaces of the filter bag 203 and filter cartridge 202 to a certain extent, a dust removal operation is required. The pulse valve 209 opens, generating a pulsed airflow that enters the filter cartridge 202 through the pulse pipe 208, causing the filter bag 203 and filter cartridge 202 to vibrate and shake off the surface dust. The operator can operate the connecting rod 210 to drive the lever 211 to shake the filter cartridge 202, further assisting in the dust removal. The shaken-off dust falls into the collection box 106 under gravity.

[0042] In summary, the dual filtration structure of the high-efficiency filter bag 203 and filter cartridge 202 effectively intercepts dust and particulate matter in flue gas, improving the purification effect and meeting environmental emission standards. The cooling system composed of the heat-conducting plate 205 and the liquid supply pipe 207 effectively cools the high-temperature flue gas, reducing damage to the filter bag and filter cartridge from high temperatures and extending the service life of the filter components. The dust removal system composed of the pulse pipe 208, pulse valve 209, connecting rod 210, and lever 211 can promptly and effectively clean the dust on the surface of the filter bag and filter cartridge, ensuring the stability of the filtration effect and reducing the workload of manual dust removal.
