Problems solved by technology

This method will cause the high-temperature gas to lose a large amount of effective energy, which is very unfavorable economically.
Similar to natural gas purification, this process also has problems such as large solvent circulation, complicated process, and large floor space, and especially at higher temperatures, the solvent is more likely to deteriorate, so there is a large room for energy-saving improvement

Abstract

The present invention discloses a gas dry method purification rotational flow and absorption coupling device. The device comprises a cyclone separator. A volute-type inlet for gas waiting for separation is arranged at the top part of the side wall of the cyclone separator. The gas dry method purification rotational flow and absorption coupling device also comprises a cyclone separator communicating device, an adsorbent moving bed conducting the impurity separation of the gas waiting for the separation, and an outlet for gas after the separation is arranged at the side wall of the adsorbent moving bed and located at the upper side of an inlet of the gas waiting for the separation. An adsorbent regeneration structure communicates with the adsorbent moving bed and an outlet for impurity gas is arranged on the adsorbent regeneration structure. The device couplings the gas-solid rotational flow separation and impurity gas adsorption separation together, at the same time conducts the purification, simplifies the technological processes, reduces the energy loss, and is wide in application ranges.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a gas dry purification cyclone adsorption coupling device. Background technique [0002] Gas purification and impurity removal technology can be divided into three levels according to the temperature of the processed gas: high temperature (hot gas) (>300°C), medium temperature (warm gas) and low temperature gas (cold gas) (<100°C). The higher the temperature, the higher the requirements for the performance and materials of the purification equipment. Purification and removal of high-temperature gas is a difficult point in the world's gas purification technology. [0003] Natural gas is rich in reserves, clean and pollution-free, and easy to transport. It is the focus of today's energy development. However, the extracted natural gas contains a large amount of solid particles, liquid water, H 2 S and CO 2 and other impurities. Solid particles will wear the pipeli...
