Pressure and flow-adjustable gas-liquid pulse pollution removing device

Abstract

The invention discloses a pressure and flow-adjustable gas-liquid pulse control system. The system comprises an electric system, a pneumatic system and a hydraulic system; a pulse valve is mounted on a pneumatic loop; an electromagnetic valve is mounted on a hydraulic loop at a liquid outlet end of a variable pump; a hydraulic loop is provided with a first pressure transmitter; a second pressure transmitter is mounted on the pneumatic loop; a third pressure transmitter is arranged on a hydraulic pipeline to be cleaned; and a PLC adjusts the pressure in the hydraulic loop and a pneumatic pipeline, so that the hydraulic loop and the pneumatic loop output matched pressure. A frequency converter is used for controlling an output flow of the variable pump to adjust a flow in the hydraulic loop. The system can generate pulsation frequency adjustable gas-liquid two-phase flows, realizes alternate mixing of liquid and gas through controlling the electromagnetic valve and the pulse valve, realizes automatic adjustment and controllable adjustment of the pressure and the flow under pulsation pressure and pulsation flow of the gas-liquid two-phase flows, and improves the gas-liquid mixing efficiency.

Description

technical field [0001] The invention relates to the technical field of hydraulic pipeline cleaning, in particular to a gas-liquid pulse decontamination device with adjustable pressure and flow rate. Background technique [0002] Statistics show that 70% to 80% of hydraulic system failures are caused by contamination inside the system. Especially for hydraulic systems with harsh working conditions and complex structures, since there are many components such as integrated blocks, joints, pipelines, and hydraulic valves that make up the system, the cleaning process becomes very difficult after pollutants are deposited on the inner surfaces of the above components. . [0003] In the existing public information about hydraulic pipeline cleaning, pulsating liquid cannot be generated in the hydraulic circuit. Therefore, the pulsating gas-liquid two-phase flow cannot be generated after the hydraulic circuit and the pneumatic circuit are mixed, and the pulse after gas-liquid mixing ...

Problems solved by technology

Especially for hydraulic systems with harsh working conditions and complex structures, since there are many components such as integrated blocks, joints, pipelines, and hydraulic valves that make up the system, the cleaning process becomes very difficult after pollutants are deposited on the inner surfaces of the above components.

[0003]In the existing public information about hydraulic pipeline cleaning, the hydraulic circuit cannot produce pulsating liquid, therefore, the hydraulic circuit and the pneumatic circuit cannot produce pulsation Gas-liquid two-phase flow, and the automatic adjustment and controllable adjustment of the pressure and flow of the pulse liquid after gas-liquid mixing cannot be realized, and the gas-liquid mixing efficiency is low, so the decontamination efficiency is low
