Magnetic slag-removing system

Abstract

The invention relates to a magnetic slag-removing system, comprising a shell, a magnetic assembly and a filter cartridge, wherein the shell is provided with a fluid inlet for allowing a fluid to enterthe shell and a fluid outlet for discharging the fluid out of the shell; the magnetic assembly is detachably mounted on the outer wall of the shell and used for adsorbing impurities in the fluid ontothe inner wall; the filter cartridge has a U-shaped cross section, and the outer wall of the filter cartridge is used for intercepting impurities in the fluid to prevent the impurities from enteringthe filter cartridge; the fluid inlet leads to the outside of the filter cartridge; and the interior of the filter cartridge communicates with the fluid outlet. The magnetic slag-removing system of the invention prolongs the service life of a filter net, reduces the replacing frequency of the filter net, and is convenient for cleaning of adsorbed impurities.

Description

technical field [0001] The invention relates to the technical field of purification equipment used in compressed gas preparation systems, in particular to a magnetic slag removal system. Background technique [0002] In the compressed air preparation system, in order to make the compressed air meet the quality requirements of the industry, it is necessary to install a primary coarse filter, a microporous filter and a freeze dryer between the air compressor and the pure gas outlet to fully remove the compressed air. solid impurities and moisture. The traditional slag removal system generally includes a filter housing, a fluid inlet and outlet, and a filter installed in the housing. When the fluid passes through the filter, most impurities will be intercepted, and the interception slag removal method is adopted. [0003] At present, carbon steel pipes are often used in compressed air pipelines, and the corrosion resistance of carbon steel materials is poor. After the system h...

Problems solved by technology

[0003] At present, carbon steel pipes are often used in compressed air pipelines, and the corrosion resistance of carbon steel materials is poor. After the system has been running for a period of time, the inner wall of the carbon steel pipes will fall off due to corrosion, and because the iron filings are hard, it is easy to damage the filter screen. As a result, the working efficiency of the entire compressed air preparation system is affected. The damage of the core filter causes iron filings to enter the subsequent compressed air pipelines and equipment, reducing the quality of compressed air, resulting in increased energy consumption and waste of resources.
