Abstract

The invention discloses a multi-phase separation device and method of mixed household refuse slurry. The device comprises a tank body, wherein a movable separation clapboard, an upper fixing plate, a separation grid and a lower fixing plate are arranged in the middle of the tank body; the upper fixing plate, the separation grid and the lower fixing plate are arranged in parallel to the movable separation clapboard and are vertically arrayed; the tank body is divided into a tank A and a tank B by the movable separation clapboard; a slag removing device is arranged at the upper part of the tank A, the tank bottom of the tank A is inclined and is provided with a gas disperser and an evacuation valve; and the tank B is an organic slurry temporary storage tank. The separation method comprises the following steps of: conveying the refuse slurry into the tank A; floating hydrophobic substances under the help of the gas disperser; and moving the movable separation clapboard so that the slurry enters the tank B after being separated through the separation grid; and evacuating insoluble sediment. The separation device disclosed by the invention has the advantages of simple structure, convenience in operation and high separation efficiency; and the total separation rate of all phases can be higher than 95%.

Description

technical field [0001] The invention relates to garbage treatment, in particular to a multi-phase separation device and separation method for mixed domestic garbage slurry. Background technique [0002] The disposal of domestic waste is a difficult problem. So far, the methods used generally include landfill, incineration, and composting. These methods have their own advantages and disadvantages. Some people have used anaerobic reactors for biochemical treatment, but in the end due to high concentration, large particles, and long fermentation time, the desired effect cannot be achieved. Contents of the invention [0003] The purpose of the present invention is to provide a multi-phase separation device and separation method for mixed domestic waste slurry. The device is simple in structure, easy to operate, high in separation efficiency, and can lay a foundation for liquefaction-biochemical treatment of organic matter in waste. [0004] The technical scheme that realizes ...
