Problems solved by technology
[0003] Nowadays, the dehydration treatment process of natural gas generally includes low temperature method, solvent absorption method and solid adsorption method, which are selected for treatment respectively. In the solvent absorption method, glycol substances are generally used as absorbents, and the processing gas is passed into the Glycol solvents separate water, but when it is actually directly fed in for continuous dehydration, the follow-up airflow often flows upward along the flow direction of the previous airflow, resulting in poor contact between the follow-up gas and the solvent, which affects the actual dehydration Effect

The invention belongs to the technical field of natural gas processing, and relates to a dehydration device for natural gas processing. The dehydration device comprises a treatment box; a fixed pipe is fixed at the bottom between the inner walls of the two ends of the treatment box; the middle position of the circumferential outer wall of the fixed pipe is rotationally connected with a storage piece with an annular structure through a bearing; the outer wall of the storage piece is in transmission connection with a driving mechanism, a storage cavity with an annular structure is formed in thestorage piece, through holes distributed in an annular array mode are formed in the circumferential inner wall, close to the fixed pipe, of the storage cavity, and a partition plate is fixed to the middle position between the inner walls of the two ends of the fixed pipe. Airflow moves towards two sides, is introduced into an air outlet cavity from the air outlet pipe at the top of the storage cavity and is exhausted from a connecting hole and an exhaust pipe; the vertical upward flowing of the airflow entering a solvent is prevented, meanwhile, the storage piece with an annular structure is slowly rotated, part of the airflow at the top of the storage cavity can be guided into the solvent again to make contact with the solvent, and therefore the actual dehydration effect of the device onnatural gas is improved.
Description
technical field [0001] The invention relates to the technical field of natural gas processing, in particular to a dehydration device for natural gas processing. Background technique [0002] Natural gas refers to a kind of combustible gas that exists in nature. It is a kind of fossil fuel, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. From the narrow definition of energy, it refers to natural reserves. It is a mixture of hydrocarbon and non-hydrocarbon gases in the formation, and natural gas often needs to be dehydrated before it is transported and used. [0003] Nowadays, the dehydration treatment process of natural gas generally includes low temperature method, solvent absorption method and solid adsorption method, which are selected for treatment respectively. In the solvent absorption method, glycol substances are generally used as absorbents, and the processing gas is passed into the Glycol solvents separate water,...
