Description

Technical Field

[0001] The utility model relates to the field of wellhead gas recovery, in particular to a special adsorption device for wellhead gas recovery. Background Art

[0002] The main component of wellhead gas is methane, but the gas usually also contains water and oil. If it is discharged directly, it will pollute the environment. However, since it contains impurities, it cannot be directly recycled and reused, so it needs to be treated before recycling.

[0003] Conventional wellhead gas recovery systems are generally composed of a pre-processor, a water vapor processor, a post-processor, a compression system, etc., wherein the main function of the water vapor processor is to adsorb water vapor in the wellhead gas, so that the wellhead gas becomes dry gas and then transported downstream. Most of the water vapor processors in the prior art adopt an adsorption processor, which is mostly composed of different adsorption layers and uses the adsorption layer to absorb water. However, the processing efficiency of this adsorption processor is low, and some of the gas after being processed by the pre-processor still contains impurities, which will cause the adsorption layer of the adsorption processor to be clogged. Based on this background, the utility model proposes a special adsorption device for wellhead gas recovery. This adsorption device adopts a combination of an air intake adsorption box and a vortex adsorber. The air intake adsorption box adopts a combined structure to filter out impurities contained in the gas, and the vortex adsorber uses the gas to enter the vortex channel to accelerate and collide with the protrusion, thereby removing water vapor. In addition, the upper end of the vortex adsorber adopts filler adsorption, which will not cause filler clogging. Utility Model Content
