Problems solved by technology
Due to temperature fluctuations in the industrial kiln as the source of the high-temperature gas to be filtered, the dust attached to the surface of the filter tube is sometimes prone to scaling, and the filter tube back-blowing soot cleaning device attached to the filter itself is difficult to effectively remove these scales piece
In addition, during the use of the filter tube, some fine dust particles will drill into the pores of the filter tube, which will cause the hole to be blocked.
The back blowing and cleaning device still cannot effectively solve the problem of hole plugging
At present, we can only rely on chemical cleaning to clean and regenerate the plugged filter tube, but this method will reduce the service life of the filter tube

The invention discloses a method and equipment for cleaning an external type gas filtration tube, which can effectively improve the technical problem that fine dust particles enter pores of the filtration tube and cause pore blockage. According to the method, the filtration tube is mounted on a blowing device used for dust cleaning of filtration tube pores; the filtration tube is used for performing operations on the filtration tube; the blowing device comprises a filtration tube rotating and supporting system, a carrying and rotating device, a middle transmission mechanism, a motor, a telescopic blowing pipe and a high-pressure gas source; the filtration tube is mounted on the filtration tube rotating and supporting system; the closed end of the filtration tube is connected with the carrying and rotating device; the carrying and rotating device is connected with the motor through the middle transmission mechanism; a blowing opening is formed in the body of the telescopic blowing tube; the carrying and rotating device drives the filtration tube to rotate, so that a high pressure gas with the pressure of 0.2-1.2 Mpa is blown out of the blowing opening and covers the whole inner surface of the filtration tube.
Description
technical field [0001] The invention relates to a cleaning method and equipment for an external filter type gas filter tube. Background technique [0002] External filter type gas filter tube (relying on the outer wall of the filter tube as the filter surface, one end of the filter tube is closed and the other end is open, the gas to be filtered penetrates from the outside of the filter tube to the inner cavity, and finally flows out from the open end) is the field of gas filtration, especially The most commonly used filter element in the field of high temperature gas filtration. At present, the external filter gas filter tubes used in high temperature gas filtration are filter tubes made of sintered metal porous materials or sintered ceramic porous materials. Due to temperature fluctuations in the industrial kiln as the source of the high-temperature gas to be filtered, the dust attached to the surface of the filter tube is sometimes prone to scaling, and the filter tube b...
