Abstract

The invention provides a rigid gas-liquid coalescing filter element, and a preparation method and device thereof. The filter element comprises a coalescing layer which surrounds the outer side of a central air inlet channel and is used for coalescing and separating liquid drops flowing in from the air inlet channel, and the filter element also comprises a liquid discharging layer which surrounds the outer side of the coalescing layer and is used for providing a liquid discharging channel for condensed liquid drops, wherein the coalescing layer is formed by drying and solidifying a first flexible material containing an adhesive, the liquid discharging layer is formed by drying and solidifying a second flexible material containing an adhesive, the first flexible material containing the adhesive is obtained by carrying out vacuum suction to enable an adhesive solution to pass through the first flexible material, and the second flexible material containing the adhesive is obtained by carrying out vacuum suction to enable an adhesive solution to pass through the second flexible material. According to the invention, the strength of the gas-liquid coalescing filter element can be improved, and requirements of a high-pressure working condition can be met.

Description

technical field

[0001] The invention relates to the technical field of gas-liquid filtration, in particular to a rigid gas-liquid coalescing filter element, a preparation method and a device thereof. Background technique

[0002] Natural gas, coal bed methane and other process gases and dry gas seal gases usually contain liquid impurities, which will affect the safe operation of downstream related instruments and equipment. Therefore, it is necessary to filter the liquid droplets in the gas. Filtration is usually performed under high pressure conditions (such as Natural gas needs to be transported after being pressurized by a compressor station, which is carried out under the pressure of 12MPa in the third line of the West-to-East Gas Pipeline. For droplets with a particle size of 0.1 to 1 μm, coalescing filters are generally used for filtration. Coalescing filters are usually used downstream of leaf separators, mist catchers, and filter separators. Large droplets in the gas...
