Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to an obliquely inserted drawer type pulse dust collector. Background Art

[0002] In recent years, incineration power generation has become the most effective way to treat urban domestic waste in a "harmless, reduced, and resource-based" manner. According to the waste incineration process, toxic gases such as sulfur dioxide and dioxins will be produced during the incineration process, as well as a large amount of high-temperature smoke. The pulse dust collector is the most widely used dust collector equipment and is also the dust collector used more frequently in waste incinerators. According to data, the main dust removal equipment in my country's operating waste incineration power plants is the pulse dust collector.

[0003] The operation and maintenance costs of a pulse dust collector are important factors to consider in its performance. The key component of a pulse dust collector is the filter element. The cage, as a supporting component of the filter element, is an important component of the pulse dust collector. Due to the short life of the filter element, especially under high temperature conditions and highly corrosive flue gas working conditions, some filter elements need to be replaced in just a few months. The installation and maintenance of the pulse dust collector in the prior art after the filter element expires is relatively complicated. If the installation and maintenance operations are not performed properly, it is also easy to cause the seal of the connection position to fail, resulting in dust leakage and environmental pollution, which needs further improvement.

The left support plate is provided with a through hole corresponding to the insertion position of the cage longitudinal reinforcement. The end of the cage longitudinal reinforcement passes through the through hole and is locked by the second nut, making the connection convenient and reliable.

[0010] As a further improvement of the utility model, a third sealing ring is fixed to the left end of the filter element to further prevent the possibility of dust-containing gas passing through the gap at the left end of the filter element into the left space, thereby improving the dust removal effect.

[0011] As a further improvement of the utility model, a rotating handle is connected to the outer end of the central connecting part of the gland to facilitate the disassembly and assembly operations.
