DNA double-helix micron-scale filter element

Abstract

The invention belongs to the technical fields of heat supply, refrigeration, water supply and purification, and in particular relates to a DNA double-helix micron-scale filter element suitable for liquid exhausting and having an extremely excellent contaminant removing effect. The DNA double-helix micron-scale filter element consists of a central shaft pipe and a filter screen with a double-helix oblique cubic structure. The filter screen is welded by surface-modified metal wires to form the double-helix oblique cubic structure, the inner wall of the filter screen is welded on a central casing pipe and the filter element integrally presents the 'DNA' double-helix structure. The DNA double-helix structure filter element has stable structure, small fluid resistance and large filtering surface area, enhances the exhausting and contaminant removing effect treatment capability, and is suitable for removing free and dissolved gases from the fluid. The heating and ventilation industry needs to remove gas from the system most urgently at present.

Description

technical field [0001] The invention belongs to the technical fields of heat supply, refrigeration, water supply and purification, and in particular relates to a DNA double-helix micron filter element suitable for liquid exhaust and decontamination with excellent effects. Background technique [0002] When gas is mixed into the liquid delivery pipeline system, due to the low density of the gas, it will accumulate to the top of the pipeline system, and with the increase of gas, the air pressure at the top of the pipeline system will increase, resulting in the drop of the liquid level in the pipeline system. In order to prevent the liquid level from dropping, an automatic exhaust valve is usually installed on the top of the pipeline system, and the gas is discharged through the automatic exhaust valve to reduce the air pressure at the top of the pipeline system. The three-dimensional wire filter element is the core component of the exhaust decontamination device, which is dire...

AI Technical Summary

Problems solved by technology

The stainless steel filter has a flat structure and is not designed for the exhaust and decontamination device, and its performance is limited; the irregular metal filter considers the mesh density, but the water flow resistance is relatively large, which increases the energy consumption of the degassing system

There are also copper mesh filter elements produced by some manufacturers, which are simply welded, without consideration of fluid resistance, surface tension, and surface area of ​​the filter mesh, resulting in a single structure of the copper mesh filter element, weak frame, poor processing effect, and cannot meet the requirements. Exhaust and decontamination of fluids in various pipelines
