Working method of vacuum pressure swing adsorption oxygen production equipment

Abstract

The invention discloses a working method of vacuum pressure swing adsorption oxygen production equipment. The equipment is provided with a Roots blower set and a Roots blower driving device. Accordingto the invention, two blowers are driven by the same motor, so energy consumption is reduced, the utilization rate of energy is improved, cost is reduced, and the volume of the equipment is reduced;a gas inflow and exhaust circulation control device and an adsorption system output adjusting device are arranged; in virtue of connecting pipelines and control valves on the equipment, a product sizeis further reduced; and the stepping motor, the adsorption system output adjusting device, an adsorption system pressure equalizing and adjusting device and the gas inflow and exhaust circulation control device are arranged, so the control of gas inflow, exhausting and pressure equalization of two nitrogen-oxygen separation and adsorption towers and the connection and exchange of the two nitrogen-oxygen separation and adsorption towers and an oxygen balance tank is realized through one stepping motor, the connecting pipelines and the control valves are reduced, the volume and the operation difficulty of traditional pressure swing adsorption oxygen production equipment are reduced, and the use convenience of the equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of oxygen production equipment; in particular, it relates to a working method of vacuum pressure swing adsorption oxygen equipment. Background technique [0002] Vacuum pressure swing adsorption oxygen equipment is a set of devices that use air to produce oxygen. Its working process is that the air source is boosted by the fan and enters the nitrogen and oxygen separation and adsorption tower, and the oxygen in the air is absorbed by the nitrogen and oxygen separation and adsorption tower. Separated from nitrogen and other gases, the separated oxygen enters the balance tank and buffer tank into the oxygen compressor, and is boosted by the oxygen compressor and sent to the customer site. The separated nitrogen and other gases are pumped out by the vacuum pump and discharged into the atmosphere , vacuum pressure swing adsorption oxygen equipment has beneficial effects such as large oxygen production and low ma...

[0002] Vacuum pressure swing adsorption oxygen equipment is a set of devices that use air to produce oxygen. Its working process is that the air source is boosted by the fan and enters the nitrogen and oxygen separation and adsorption tower, and the oxygen in the air is absorbed by the nitrogen and oxygen separation and adsorption tower. Separated from nitrogen and other gases, the separated oxygen enters the balance tank and buffer tank into the oxygen compressor, and is boosted by the oxygen compressor and sent to the customer site. The separated nitrogen and other gases are pumped out by the vacuum pump and discharged into the atmosphere , vacuum pressure swing adsorption oxygen equipment has beneficial effects such as large oxygen production and low maintenance cost, but the existing vacuum pressure swing adsorption oxygen equipment is still too large in size, has too many internal components, and consumes more energy. Control valves and connections There are too many pipelines, and the operation is extremely complicated. Therefore, the appearance of a vacuum pressure swing adsorption oxygen equipment that reduces internal components, reduces volume, reduces energy consumption, improves energy utilization, and reduces control complexity and the number of pipelines is imminent.
