Oxygen pressure leaching flash exhaust control structure and control method

Abstract

The invention discloses an oxygen pressure leaching flash exhaust control structure and a control method thereof, and relates to the technical field of chemical equipment. The oxygen pressure leaching flash exhaust control structure includes a valve body, the liquid inlet of the valve body is fixedly connected with one end of the liquid inlet pipe, and the inner cavity of the valve body communicates with the inner cavity of the liquid inlet pipe. The liquid outlet is fixedly connected with one end of the liquid outlet pipe, the liquid inlet pipe is provided with a throttling slow-release mechanism, and the liquid outlet pipe is provided with a bubble elimination mechanism, and the throttling slow-release mechanism includes an orifice plate, a rotating auxiliary ball, and a collector ring , a buffer mechanism and a diversion protrusion, the side curved surface of the orifice plate is slidably connected with the inner wall of the liquid inlet pipe. The oxygen pressure leaching flash exhaust control structure uses the throttling slow release mechanism and the air bubble elimination mechanism to achieve the effect of disturbing the flow of the fluid that is about to be discharged into the valve body and the fluid that is discharged through the valve body, thereby fully avoiding entrainment. The fluid part with many bubbles causes local severe erosion on the surface of the inner cavity of the valve.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an oxygen pressure leaching flash exhaust control structure and a control method thereof. Background technique [0002] In the field of oxygen pressure leaching, flash evaporation equipment is very important, and there are many linkage equipment. When there is an abnormality in the single flash evaporation unit and the exhaust pipeline valve group, it is necessary to stop the operation of other flash evaporation and related equipment to exhaust and cool down. In order to deal with abnormal equipment, the working principle of flash evaporation equipment is: after high-pressure saturated liquid enters a relatively low-pressure container, due to the sudden drop in pressure, these saturated liquids become saturated vapor and saturated liquid under the pressure of a part of the container. It is usually used in the recovery of boiler drainage in thermal power plants and geot...
