Description

Technical Field

[0001] This utility model relates to the field of environmental protection and waste gas treatment, and discloses a new type of bag filter dust collector for waste gas incinerators. Background Technology

[0002] In the field of environmental protection and waste gas treatment, waste gas incinerators are key equipment for treating industrial waste gas. Their emissions often contain a large amount of dust particles, which, if directly emitted, would cause serious environmental pollution. Therefore, highly efficient dust removal equipment is necessary. Baghouse dust collectors, with their advantages of high filtration efficiency and wide applicability, are widely used in the tail gas purification process of waste gas incinerators.

[0003] Currently used traditional baghouse dust collectors for waste gas incinerators experience dust accumulation on the filter bag surface over time. If not cleaned promptly, this reduces the filter bag's permeability and impacts dust collection efficiency. Traditional cleaning methods, such as simple tapping or manual cleaning, have limited effectiveness and may damage the filter bags due to improper force. Furthermore, the lack of effective buffering during cleaning leads to significant overall equipment vibration, potentially affecting the stability of component connections and shortening the equipment's lifespan.

[0004] Currently used traditional baghouse dust collectors for waste gas incinerators often encounter problems in practical applications. Dust tends to accumulate in arches at the ash hopper and hopper opening due to mutual compression and adsorption, preventing smooth dust discharge and even clogging the hopper opening. This not only affects the continuous operation of the equipment but also requires frequent shutdowns for manual unclogging, increasing maintenance costs and operational intensity. Traditional equipment lacks a dedicated arch-breaking structure, making it difficult to effectively solve the dust arching problem and limiting the operating efficiency and stability of baghouse dust collectors. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a new type of bag filter dust collector for waste gas incinerators, which aims to improve the problems of dust accumulation in filter bags and dust arching at the hopper opening in the prior art.
