Maintenance-free slurry washer applied to hazardous environment and working method of maintenance-free slurry washer

Abstract

The invention relates to a maintenance-free slurry washer applied to a hazardous environment and a working method of the maintenance-free slurry washer. The washer comprises a pulse jet conveying system, a slurry washing and filtering system and a user terminal workstation. In the process of washing slurry, the slurry can be washed by utilizing a gas-liquid-solid three-phase fluidized bed; washed waste liquid is leached through a filter net at the bottom of the three-phase fluidized bed; and washed clean slurry can be conveyed to a storage area or an area to be processed through the pulse jet conveying system without a mechanical movable part. The operation power of the whole washer completely comes from high-pressure gas and is realized by being dependent on a gas ejector; and the slurry washer disclosed by the invention does not comprise the mechanical movable part which is in direct contact with a hazardous fluid and can be remotely controlled, therefore, maintenance requirements can be sufficiently reduced under hazardous environments, such as a radioactive environment, a corrosive environment, a toxic environment, a high-temperature environment and the like, thus, personal safety of maintenance staffs and operators can be ensured.

Description

technical field [0001] The invention relates to the technical field of solid particle washing, in particular to a maintenance-free mud scrubber suitable for use in hazardous environments and a working method thereof. Background technique [0002] In nuclear energy, chemical industry, metallurgy, mining and other industrial production, it often involves the washing process of solid materials with radioactivity, corrosion, toxicity, high temperature, etc. For the washing of these dangerous materials, if traditional washing methods are used, such as stirred tanks, cross-flow filter washing, etc., during the washing process, whether it is radioactive or corrosive, it is easy to cause accelerated damage to mechanical movable parts and sealing materials. Therefore, frequent maintenance and replacement operations must be carried out on damaged parts, which not only leads to high maintenance costs, but also requires personnel to perform operations and maintenance at close range. se...

Problems solved by technology

For the washing of these dangerous materials, if traditional washing methods are used, such as stirred tank, cross-flow filter washing, etc., during the washing process, whether it is radioactive or corrosive, it is easy to cause accelerated damage to mechanical movable parts and sealing materials. Therefore, frequent maintenance and replacement operations must be carried out on damaged parts, which not only leads to high maintenance costs, but also requires personnel to perform operations and maintenance at close range. serious personal injury

[0003] Therefore, for dangerous solid materials, in order to avoid maintenance operations during use and personal injury to operators, it is of great significance to develop a maintenance-free, remote-controlled mud scrubber. There is no such device yet
