Problems solved by technology

The original pleated filter element reinforced the filter element itself by adding a ring support to the inner ring, but there were problems that the pleats of the filter element were easy to accumulate dirt or the flow rate of the filter element was uneven due to the extrusion of the filter material, which urgently needed to be improved.

Abstract

The folding type natural gas filter element is provided with a first axis, and the filter element comprises a plurality of folding units which are distributed around the first axis and are integrally formed; the folding unit comprises a first filtering layer; the second filter layer is formed on the first filter layer and is relatively close to the first axis side; the third filter layer is formed on the first filter layer and is relatively far away from the first axis side; in a non-filtering state, the second filtering layer and the third filtering layer can maintain that a first included angle with an opening facing the first axis is formed on one side, relatively close to the first axis, in each folding unit; a second included angle with an opening far away from the first axis is formed between every two adjacent folding units; in a filtering state, the second filtering layer and the third filtering layer can maintain the first included angle within a first preset range, and can maintain the second included angle within a second preset range. The folding type natural gas filter element has the advantages of being high in structural strength, not prone to deformation and capable of preventing non-uniform flow of the filter element due to natural gas extrusion.

Description

technical field [0001] The present disclosure generally relates to the technical field of natural gas filter elements, and particularly relates to a folded natural gas filter element. Background technique [0002] Natural gas filter separators are widely used in long-distance natural gas pipelines, mainly to remove solids and liquid droplets in natural gas, and play a very important role in protecting important equipment such as compressors, gas turbines and flow meters. Natural gas needs to be filtered in the filter before entering the long-distance pipeline to reduce the solid and droplet impurities in it. As the core component of the filter, the filter element needs to be replaced regularly. The pleated filter element is widely used because of its large filtering area. The original pleated filter element reinforces the filter element itself by adding annular support to the inner ring, but there is a problem that the pleats of the filter element are easy to accumulate dirt...
