Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, it relates to a waste gas purification device for electrode paste production. Background Technology
[0002] The waste gas generated during the electrode paste production process mainly originates from raw material processing and technological stages. The calcination, crushing, and screening processes in the raw material handling stage produce dust-containing waste gas, primarily composed of carbon particulate matter (such as graphite and petroleum coke dust). During the mixing and molding stage of the technological process, the volatilization of binders such as asphalt generates organic waste gas (such as volatile organic compounds). Some raw materials (such as asphalt) contain elements like sulfur and nitrogen, which may produce acidic gases. Therefore, the production process involves two main processes: purifying the waste gas, specifically the dust and organic waste gas. Dust waste gas is generally treated by direct filtration using filter bags or screens. However, due to the high dust content, the filter bags or screens require frequent cleaning, severely impacting purification efficiency. Furthermore, cleaning requires disassembling numerous parts of the purification device, resulting in generally poor cleaning effectiveness. Utility Model Content

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a waste gas purification device for electrode paste production, which has the following beneficial effects: 1. By setting up a cyclone separator, air inlet pipe, spiral plate, central pipe, connecting pipe, filter cartridge, filter bag, and exhaust pipe, when purifying dusty exhaust gas, the dusty exhaust gas is quickly blown into the cyclone separator by an external fan through the air inlet pipe. It rotates rapidly along the spiral air channel formed by the spiral plate. The dust particles are separated from the gas under the action of centrifugal force.
