Description

Technical Field

[0001] The utility model relates to the technical field of sand removal separators, in particular to a sand removal and separation integrated filter cartridge. Background Art

[0002] The natural gas produced from fracturing wells or formation sand-producing wells generally carries a large amount of sand particles, and these high-speed flowing sand particles can cause great harm to the ground gas gathering system and even cause serious safety accidents.

[0003] The desanders in the existing desander technology are generally divided into cartridge desanders or cyclone desanders. Cartridge desanders can achieve fine sand removal and are used in production conditions with regular sand discharge and stable operation, but the operation and maintenance are cumbersome, the accessories are frequently replaced, and the operation faces a high operational risk. Since the cyclone desander uses centrifugal force, it cannot effectively separate ultrafine sand or dust. Therefore, it is mainly used in environments where the sand removal accuracy requirements are not strict. It can also be used in construction environments where the drainage or production system is unstable, the sand output is expected to be large, and the production pressure fluctuates greatly. It has a wide range of applications.

[0004] However, in actual use, the sand or other hard particles contained in the gas can easily penetrate the filter cartridge installed in the filter, causing the particulate matter to enter the downstream pipeline, making it inconvenient to replace the filter cartridge later.
