Embodiment Construction

[0050]In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0051] Since the magnetic levitation centrifugal blower can recover more kinetic energy than the ordinary blower, the solution of the present invention aims at recovering the kinetic energy of the magnetic levitation centrifugal blower. However, regardless of the cost or other types of blowers that can recover more kinetic energy The blower energy recovery system still applies.

Abstract

The invention provides a method and system for air blower energy recovery control and a storage medium. The method comprises an air blower, a power supply, a frequency converter, a first contactor, a second contactor, a DC / DC converter, a storage battery, a UPS and a PLC, wherein the power supply is connected with a main circuit of the frequency converter through the first contactor; the UPS is connected with the power supply, the storage battery, the second contactor and the PLC, and the UPS is used for supplying power to the second contactor and the PLC based on electric energy provided by the power supply or the storage battery; the PLC is used for controlling the opening and closing states of the first contactor and the second contactor; and the air blower is sequentially connected with the frequency converter, the second contactor, the DC / DC converter and the storage battery, when a main loop of the frequency converter loses power and the second contactor is closed, the kinetic energy of the air blower can be converted into electric energy through the frequency converter, the electric energy is output to the DC / DC converter through the second contactor, and the electric energy is stably output to the storage battery after being converted by the DC / DC converter. According to the method and system for air blower energy recovery control and the storage medium, the energy of the magnetic suspension centrifugal air blower can be recovered, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of energy recovery, in particular to a method and system for energy recovery control of a blower. Background technique [0002] The magnetic levitation centrifugal blower is a high-volume, low-pressure blower device, which uses core technologies such as high-speed permanent magnet motors, electromagnetic levitation bearings, and direct-connected high-speed three-dimensional flow impellers. The frequency converter is used to adjust the speed to realize the adjustment of the air volume or air pressure of the blower. The electromagnetic bearing technology is used to minimize mechanical friction and reduce equipment vibration and noise. The rotor of the magnetic levitation centrifugal blower works in a vacuum-like space, and the friction force of the rotor is small during the rotation process, which can recover more kinetic energy than ordinary blowers. [0003] At present, the applicability of the energy recov...
