Abstract

The invention discloses a double-screw high-pressure surplus energy recycling device which comprises a device housing, a rear end cover, a front end cover, a bushing, a drive screw, a driven screw, a drive friction wheel, a driven friction wheel, a bearing block and a mechanical seal cover, wherein the bushing is arranged inside the device housing, one end of the device housing is connected with the rear end cover, one end of the bushing inside the device housing is connected at the inner side of the front end cover, the outer side of the front end cover is connected with one side of the bearing block, the mechanical seal cover is arranged inside the bearing block, and the drive screw and the driven screw are arranged inside the bushing. Compared with a common multi-stage centrifugal hydraulic turbine, the double-screw high-pressure surplus energy recycling device has the high energy recovery rate, and meanwhile has the advantages of being stable in medium transmission, weak inn pressure pulsation, small in mechanical vibration, low in noise, high in rotation speed, small in flow and continuous in work.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a device for recovering energy by utilizing the pressure energy of a working fluid, in particular to a twin-screw high-pressure residual energy recovery device. Background technique [0002] Energy recovery is to convert waste energy forms that cannot be stored and reused, such as thermal energy, mechanical energy, light energy, etc., into electrical energy for storage and reuse. [0003] Nowadays, the high-pressure waste water in industrial production is discharged without being fully utilized, and its energy cannot be fully utilized. If the energy is collected with an energy recovery device, it will save energy and reduce emissions, and the energy will also bring More use value. [0004] For the existing devices that utilize the pressure energy of the working medium for energy recovery, such as water turbines, steam turbines, and pumps as hydraulic turbines, there are specific requireme...
