[0002] Since sand production is common in natural gas production wells in shale gas areas, when the natural gas carrying sand and gravel flows at high speed in the pipeline, the sand and gravel can easily cause puncture leakage in equipment and pipelines. To avoid the impact of sand and gravel on natural gas production, desanders are installed in natural gas wells in shale gas areas to remove sand and gravel from the natural gas, thereby preventing sand and gravel from causing puncture leakage in downstream equipment and pipelines. During the use of the desander, the desander filter element needs to be cleaned and replaced according to the sand production of the gas well, the gas flow rate, and the pressure difference between the upstream and downstream of the desander.
