Drying tower and natural gas purification system

Abstract

A drying tower and a natural gas purification system, in particular to a drying tower and a natural gas purification system. The inner cavity of the drying tower can contain desiccant, including a tower body and an outlet pipe, the inner port of the outlet pipe is connected to the inner cavity of the tower body, and a device capable of filtering the desiccant is installed at the inner port of the outlet pipe. filter cover. Through the setting of the filter cover, the desiccant can be loaded to the bottom of the tower body, and the desiccant is prevented from falling into the outlet pipe, thus, the durability of the drying tower is obviously improved, and the manufacturing cost and failure rate are reduced at the same time. The present invention also provides a purification system including a drying tower.

Description

technical field [0001] The invention relates to the technical field of energy and chemical industry, in particular to a drying tower and a natural gas purification system. Background technique [0002] In the field of energy and chemical industry, various system equipment are widely used, among which, for the purification process of natural gas, a drying tower is required. [0003] In recent years, there have been increasing requirements for the durability improvement of the drying tower during the drying process of natural gas, as well as the reduction of failure rate and cost. Therefore, improving durability while reducing cost and failure rate has become the design goal . [0004] In the existing technology, such as figure 1 As shown, the drying tower includes an inner cavity 1, a sieve plate 2 arranged in the inner cavity, and an outlet pipe 3 located on the bottom side of the sieve plate 2 and communicating with the outside. On the sieve plate 2, desiccant for drying ...

AI Technical Summary

Problems solved by technology

For this structure, since the desiccant is a small particle, in order to ensure that the desiccant is completely carried by the sieve plate 2 and does not fall, it is necessary to seal the sieve plate 2 and the inner cavity 1 firmly, and the inner cavity 1 and the sieve plate are required. 2. The dimensional accuracy of the separate processing is high and can be closely attached, which results in a high production cost of the drying tower. If the desiccant falls at the gap of the gas, the desiccant will enter the outlet pipe 3 at the bottom together with the natural gas, which will cause damage to the equipment such as blockage, and require shutdown for repair and maintenance. Therefore, the durability of the drying tower is low and the failure rate is high

[0005] In the above prior art, the durability of the drying tower is low, and the defects such as high failure rate and cost have become technical problems that those skilled in the art need to solve at present
