Description

TECHNICAL FIELD

[0002] High-temperature gas filtration refers to a technology for effectively filtering gas under high-temperature conditions, which is widely used in industrial processes such as waste gas treatment of boilers and furnaces, metal smelting, and chemical production. The purpose of high-temperature gas filtration is to remove solid particles, smoke, dust, and other pollutants from the gas to meet environmental protection standards or protect subsequent equipment requirements.

[0003] According to the patent with the publication number CN114177709A, a high-temperature gas filtration device is disclosed. In the missile engine test bench, the high-temperature test gas used for testing has a temperature of up to 1050 degrees Celsius (K), a pressure of up to 1 megapascal (MPA), and an air flow of up to 60 kilograms per second (KG / S). Not only does it need to filter impurities from the test gas to protect downstream test components, but it also requires gas rectification of the test gas to meet aerodynamic characteristics. Therefore, the filter cartridge is supported by the first and second support frames at both ends, which can meet the requirements of high-flow and high-performance backflushing for test gas impurity filtration. Moreover, the diameter of the filter cartridge gradually decreases from the first end to the second end, meeting the demand for airflow integration. Additionally, both the bracket and the filter cartridge are made of high-temperature-resistant materials, which can meet the requirements of high-temperature and high-pressure environments.

[0004] However, the above-mentioned filter device has the following disadvantages during use:

During the filtration of high-temperature gas, and under the long-term impact of high-temperature gas, the filter plates are easily corroded by high-temperature gas, which can cause damage to the filter plates, resulting in insufficient structural stability. Therefore, when replacing the filter plates, the device needs to be disassembled as a whole, and then tools are used to tighten the screws to remove the filter plates, making the disassembly process more complicated and increasing the difficulty of replacing the filter plates.
