Description

Technical Field

[0001] This invention relates to the field of natural gas equipment technology, specifically to a deep drying adsorption mechanism for natural gas dehydration. Background Technology

[0002] Natural gas, as a clean and efficient fossil energy source, is widely used in fields such as residential gas supply, industrial production, liquefied energy storage, and chemical raw material preparation. The raw wet natural gas obtained from oil and gas field extraction usually contains saturated water vapor, along with small amounts of impurities such as condensate oil, hydrogen sulfide, carbon dioxide, and suspended solids. Therefore, after natural gas is extracted, it requires multiple cleaning processes, one of which is the dehydration of the natural gas. Currently, the mainstream technologies for natural gas dehydration in the industry mainly include three categories: low-temperature condensation dehydration, triethylene glycol absorption dehydration, and solid adsorption deep dehydration. These technologies are widely used in natural gas purification scenarios under various operating conditions. However, in the later stages of deep dehydration, solids are generally used to absorb the moisture, followed by backflushing with high-temperature dry gas to remove the adsorbed water. The cooled wastewater is then recycled, reducing property costs. In traditional solid adsorption processes, because natural gas requires continuous dehydration, either the dehydration process must be stopped after adsorption is complete for solid replacement, or the space must be increased to allow multiple dehydration units to be used in rotation. The former reduces work efficiency, while the latter increases space requirements and wastes resources. Summary of the Invention

[0003] The purpose of this invention is to provide a deep drying adsorption mechanism for natural gas dehydration, so as to solve the problems mentioned in the background art.

[0004] By adopting the above technical solutions, it is possible to continuously perform deep dehydration of natural gas and achieve intelligent operation, thereby reducing the waste of site resources.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: natural gas is dehydrated by solid adsorption, and an adsorption mechanism and a replacement mechanism are provided. After the natural gas enters, it is adsorbed and dehydrated multiple times by the solid in the adsorption mechanism and the solid in the replacement mechanism in sequence, thus completing the dehydration conversion rate. After the bottom adsorbed solid absorbs water, its weight increases, which squeezes the spring downward and triggers the replacement alarm. Then, the solid is pushed out of the baffle by the scraper for drying. At the same time, the push plate in the replacement mechanism above pushes the adsorbed solid inside it to fall onto the bottom adsorption plate to continue the operation, thus completing uninterrupted adsorption replacement. The dried adsorbed solid is transported to the top replacement mechanism through the conveying pipe, which increases the adsorption efficiency and reduces the consumption of site resources.
