Abstract

The invention discloses a natural gas filtering device, which comprises an upper cover body, a cylindrical body and a filter core; a sealing plate is arranged at the bottom of the filter core; Connected to the top of the cylinder, a liquid containing cavity is opened in the cylindrical extension section, a liquid inlet flow channel is opened on the connecting cylinder, an air inlet pipe is arranged on the connecting cylinder, and a plurality of holes are evenly opened along the circumferential direction on the cylindrical extension section. The air outlet communicated with the liquid containing chamber, the filter element is arranged on the cylinder body and connected with the bottom of the connecting cylinder, the filter element completely surrounds the cylinder extension section; the connecting cylinder is provided with an outlet flow channel. In the process of filtering, the natural gas is first contacted with water, and after the natural gas is in contact with water, the impurities in the natural gas will aggregate into clusters, and the diameter of the impurities will increase, so that when the natural gas passes through the filter element, the impurities can be completely blocked by the filter element, thereby improving Filtering effect of natural gas.

Description

technical field [0001] The invention relates to the field of natural gas processing, in particular to a natural gas filtering device. Background technique [0002] Untreated natural gas contains a small amount of impurities, which can affect the combustion of natural gas and cause blockage of gas-consuming equipment. Therefore, before the natural gas is put into use, it is necessary to filter the natural gas to remove impurities in the natural gas. [0003] At present, natural gas is filtered mainly by filters with filter elements. Due to the small size of the impurity particles, some impurities whose diameter is smaller than the aperture of the filter element will pass through the filter element, resulting in poor filtering effect. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a natural gas filtering device with good filtering effect. [0005] The object of the present invention is a...
