Abstract

The invention provides a VPSA gas separation system which comprises a plurality of turbines arranged in parallel and a gas separation assembly, the turbines are used for conveying air to the gas separation assembly or vacuumizing the gas separation assembly, each turbine is connected with a driving motor and a frequency converter, and all the frequency converters are in communication connection with a control device. The control device is used for controlling output of the frequency converter. The problems that in the prior art, a customized large centrifugal unit is high in manufacturing cost, high in efficiency, small in working interval and small in adjustable working condition range are solved, and the effects that the working condition adjusting range of the centrifugal unit is expanded, and the production cost and the maintenance cost of the centrifugal unit are reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of VPSA vacuum pressure swing adsorption, in particular to a VPSA gas separation system and a control method thereof. Background technique [0002] In the existing VPSA gas separation system, the mainstream is based on the Roots machine, and a single or double Roots blower and Roots vacuum pump are used as the power equipment of the system. The advantages and disadvantages of the application of Roots blower as power equipment in VPSA gas separation system have been elaborated (such as CN108678973A). The characteristics of Roots blower such as low efficiency, large noise, and small capacity have seriously restricted the development of the VPSA industry. [0003] The application of centrifugal blower and centrifugal vacuum pump in the VPSA gas separation system can bring many advantages, but also requires targeted improvement and design of the centrifuge. The application of the centrifuge further improves the ...
