Problems solved by technology

If the thermal hydrolysis device for domestic waste is simply used in the thermal hydrolysis treatment of kitchen waste, there will obviously be many technical problems, so the thermal hydrolysis technology of domestic waste cannot be directly applied to kitchen waste Processing

Abstract

The invention discloses a kitchen garbage pyrohydrolysis method and a device thereof. The device comprises a tank body, wherein the top of the tank body is provided with a feed port, and the bottom of the tank body is communicated with a drain pipe; the lower part of the side wall of the tank body is provided with a discharge hole, the upper part of the side wall of the tank body is provided with at least three steam inlets, and the steam inlets extend to the upper part of the discharge hole along a steam pipeline; and the side wall of the tank body is provided with an exhaust port. The processing method of the kitchen garbage provided by the invention comprises the following steps of: transferring the kitchen garbage to a tank body of a pyrohydrolysis device so as to carry out pyrohydrolysis, after finishing pyrohydrolysis, discharging the materials from the discharge hole, and realizing the treatment on the kitchen garbage; and the treatment process is simple, the device is directly fed so as to carry out pyrohydrolysis after a bag is opened, labor and other sorting process are saved, the failure rate of a processing line is reduced, and the operating efficiency is improved.

Description

technical field [0001] The invention relates to a thermal hydrolysis method of kitchen waste and a device thereof, belonging to the technical field of domestic waste treatment. Background technique [0002] Kitchen waste is a general term for leftover meals (excluding swill) discarded by households, hotels, restaurants and other eating and drinking units, accounting for about 40-60% of domestic waste, and is an important part of domestic waste. Kitchen waste is related to domestic waste. It has the following characteristics: 1) The content of organic matter such as crude protein and crude fiber is relatively high, which is perishable and odorous; 2) The water content is high, and leachate is easy to produce, which brings inconvenience to the collection, transportation and treatment of garbage; 3) The calorific value is low , limiting the application of incineration technology. [0003] At present, before the harmless treatment and reuse processing of kitchen waste, the wast...
