Adjusting method for increasing pressure of liquid phase outlet of disc separator

Abstract

The invention discloses an adjusting method for increasing pressure of a liquid phase outlet of a disc separator. The adjusting method is characterized in that a multiplex end face seal which is radially distributed is arranged in a liquid phase backpressure forming area in the discharging direction, and a centripetal pump is arranged in the backpressure forming area; when the pressure of the backpressure forming area changes, the multiplex end face seal keeps the output end of the centripetal pump to be isolated from the space in a housing; the multiplex end face seal is provided with a watercooling system. Through the design of the multiplex end face seal, the method has the capabilities of pressure resistance, wear resistance and automatic compensation, the leakage phenomenon of a liquid outlet device structure under high backpressure when an existing centripetal pump is applied is avoided, the application range of the separator is greatly expanded, and the separation clarity is improved.

Description

technical field [0001] The invention relates to the disc separator technology, in particular to an adjustment method for increasing the outlet pressure of the liquid phase of the disc separator. Background technique [0002] The disc separator is a kind of decanter centrifuge, which uses the powerful centrifugal force generated by the high-speed rotation of the drum and the enhanced separation of the disc to make the suspension or emulsion to be clarified, separated and concentrated respectively. Purpose, that is, liquid-liquid, liquid-solid, liquid-liquid-solid separation; due to the high separation factor, the disc separator is especially suitable for separating materials that are difficult to separate, such as viscous liquid and fine solid particles. Materials such as suspensions or emulsions composed of liquids with similar densities. Disc separator is the most widely used decanter centrifuge, widely used in chemical industry, medicine, petroleum, transportation, food, ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the above problems, that is, although increasing the back pressure can solve the separation requirements of different materials when the disc separator separates materials, the adjustment range cannot meet the requirements due to leakage in the structure of the commonly used liquid outlet device, thus An adjustment method for increasing the outlet pressure of the liquid phase of a disc separator is provided
