AI Technical Summary
In the current fracturing fluid processing, cleaning or replacing filter elements or filter bags requires machine downtime, resulting in poor discontinuity in filtration efficiency and affecting the filtration efficiency of the fracturing fluid.
A bag filter was designed, which uses a detachable filter cartridge and liquid supply assembly. The flow path is adjusted in the liquid distribution tube by a displacement plate, so that the filter bag can be replaced and cleaned without stopping the machine, ensuring the continuity of the filtration process.
This allows for the replacement and cleaning of filter bags without shutting down the system, improving the filtration efficiency and continuity of fracturing fluid.
