Process system for realizing single-stage efficient washing solid-liquid separation

Abstract

The invention discloses a process system for realizing single-stage efficient washing solid-liquid separation in the field of solid hazardous waste resource treatment, which comprises an electric cabinet, an online monitoring device, a filter press, a filter press auxiliary device, a filtrate and solid phase discharge device and a medicament device, the electric cabinet is connected with the on-line monitoring device, the filter press, the filter press auxiliary device and the medicament device, the inlet end of the filter press is connected with the filter press auxiliary device, and the outlet end of the filter press is connected with the filtrate and solid phase discharge device. The process system for realizing solid-liquid separation can automatically control production on line, can automatically adjust the concentration of the prepared solution according to different batches of raw materials, can once finish removal of a certain salt required by a washing pretreatment process, and is simple in process, less in fault and low in maintenance cost.

Description

technical field [0001] The invention relates to the equipment of a solid and hazardous waste resource disposal production line, and more specifically, to a process system for realizing single-stage high-efficiency water washing solid-liquid separation. Background technique [0002] With the sustained and rapid development of the domestic economy and the rapid improvement of national living standards, the annual output of municipal solid waste has also increased significantly; one of the important means of municipal solid waste disposal at this stage is to use waste incineration to generate electricity through high-temperature incineration of municipal solid waste , can effectively sterilize, reduce volume, and reduce volume. At the same time, it can provide a large amount of heat energy for heating or power generation, and can recover energy to the maximum extent. However, the incineration fly ash produced during the waste incineration process is rich in organic pollutants su...
