Down-hole desilting adsorption protecting device

Abstract

The invention relates to a purification device for water consumption systems, in particular to a downwell sediment adsorption and protection device. The invention provides a downwell sediment adsorption and protection device that is characterized by simple structure and simple and convenient installation but no pollution. The purification device comprises a magnetic filter mechanism; the filter mechanism is connected with a magnetic column 1. The magnetic filter mechanism comprises a drum body 2 and the magnetic column 1 inside the drum body 2; the drum body 2 inside is composed of a drum body mesh screen 3 outside the magnetic column 1; one end of the drum body 2 is arranged with a mesh screen 4. The drum body 2 is positioned with holes 5. Utilization of the structure can fulfill filteration, magnetization and adsorption as well as sediment effects for such impurities as mechanical impurities, sand grains and scraps and etc in wate. Meanwhile, the invention can lower the expansion ratio of clay minerals, improve water absorption index of formations, and suppress propagation of saprogens. Moreover, the invention cn also purify water quality to eliminate mechanical impurities and ferromagnetic corrosive substances.

Description

1. Technical field: [0001] The invention relates to a purification device for a water system, in particular to an adsorption protection device for downhole sedimentation. 2. Background technology: [0002] Scaling, corrosion and microbial growth are the main hazards of water systems, including oilfield water injection systems.
