Problems solved by technology

Due to the size, the complete set of skid-mounted equipment is limited. Even after the project is skid-mounted, due to the limited transportation height, it needs to be disassembled and transported separately during transportation. The overall integrity of the device has not been achieved; based on the above situation, it is necessary and has special significance and value to miniaturize the equipment

Abstract

The invention discloses a container grid and method for pressure swing adsorption, relates to the field of gas purification and separation. The container grid is used for purifying hydrogen in a hydrogen production process, and comprises a container grid body, an adsorption column group is arranged in the container grid body, the adsorption column group comprises adsorption columns, and a gas inlet and a gas outlet of the same group of adsorption columns are arranged in parallel; and the adsorption columns are fixed in the container grid body through a supporting bottom frame and a fixing frame. According to the method, adsorption, primary uniform pressure reduction, forward pressure release, secondary uniform pressure reduction, reverse pressure release, flushing, secondary uniform pressure increase, primary uniform pressure increase and final pressure increase are conducted on the adsorption column group through the container grid, skid-mounting, integration and factorization are conducted on a gas purification device, the matching effect between parts is good, and the container grid has the advantages of complete adsorption and desorption, high stability and reliability, simple and reliable process method, realization of the effects of continuous input of the raw material gas and continuous output of the product gas, meeting of the continuous demands of factories, and obtaining of the economic values.

Description

technical field [0001] The invention relates to the field of gas purification and separation, and is used for purifying hydrogen in a hydrogen production process, in particular to a container and method for pressure swing adsorption. Background technique [0002] In the field of gas purification, pressure swing adsorption technology is more and more widely used for gas purification and separation. This process technology is simple, low investment, small footprint, and easy to operate. More and more customers choose to use pressure swing adsorption process. . In the past, most customers and suppliers basically chose on-site installation and commissioning for the construction of devices in pressure swing adsorption technology. With the development of industrialization, customers have different requirements for processing gas volume, different construction scales, and different construction period requirements. Customers are faced with a choice dilemma. . At present, more and...
