TECHNICAL FIELD

[0001] The utility model relates to filter device technical field, concretely is a kind of energy-saving natural gas filter device. BACKGROUND

[0002] Energy-saving natural gas filter device is mainly used to filter solid impurities in natural gas. During the extraction, transportation and storage of natural gas, various impurities may be mixed in. These impurities include, but are not limited to, sand particles, rust, dust, etc. Sand particles may be carried out from the formation during the extraction of natural gas. Rust is produced due to the corrosion of the natural gas pipeline system. Dust may come from the surrounding environment or be mixed in during the natural gas treatment process.

[0003] After the natural gas is extracted from the gas well, it is transported through the gathering pipeline. The rust on the inner wall of the pipeline may fall off and enter the gas flow. If these solid impurities are not filtered out and enter the gas equipment, it may cause damage to the equipment, affect the normal operation of the equipment, and reduce the service life of the equipment. During the working process of the filter device, the impurities filtered out will gradually accumulate. As the filtering process continues, the solid impurities will accumulate on the surface of the filter element or filter screen of the filter device. When the impurities accumulate to a certain extent, it will cause the filtering efficiency of the filter device to decrease. For example, after the pores of the filter screen are blocked by a large amount of impurities, the resistance of the natural gas passing through the filter screen will increase, and the flow rate will decrease, resulting in a decrease in the filtering capacity. Therefore, we propose an energy-saving natural gas filter device to solve the above problems. SUMMARY
