Method and device for intensifying kitchen waste microorganism compost by using cooking fume

Abstract

The invention discloses a method and a device for intensifying kitchen waste microorganism compost by using cooking fume. The method comprises the following steps: crushing kitchen wastes, adding a microorganism auxiliary material, guiding cooking fume into the kitchen wastes, and mixing with the kitchen wastes for a preset time so as to prepare a biological organic fertilizer, continuously stirring the kitchen wastes when being mixed, and controlling the mixing temperature to be constant temperature. The invention further discloses a device for applying the method. The device comprises a tank body, wherein a microorganism auxiliary material inlet and a kitchen waste inlet are formed in one end of the tank body; a biological organic fertilizer outlet is formed in the other end of the tank body; a stirring shaft is arranged inside the tank body and is used for stirring the kitchen wastes inside the tank body; the kitchen wastes are pushed to the biological organic fertilizer outlet form the kitchen waste inlet when being stirred; a cooking fume inlet and a tail gas outlet are formed in the upper part of the tank body.

Description

technical field [0001] The invention relates to a method for using cooking fume to strengthen the microbial composting of kitchen waste, in particular to the utilization of waste heat of kitchen cooking fume and contained chemical components. The invention also relates to a device for enhancing microbial composting of kitchen waste by using oil fumes. Background technique [0002] At present, air pollution is becoming more and more serious around the world, and the pollution sources are diverse, including industrial emissions and domestic emissions, and the methods of treatment also require adaptation. In various types of restaurants, the amount of cooking fume is relatively large. The cooking fume contains a certain amount of heat and certain chemical components, such as carbon dioxide, carbon monoxide, acrolein, polycyclic aromatic hydrocarbons, etc., and is an obvious source of domestic pollution. How to deal with it It is an urgent environmental protection problem to ...

Problems solved by technology

[0003] In addition, restaurants or residential areas will generate a large amount of various domestic waste. Although waste classification is also adopted, it is usually disposed of by crushing and burying. Among them, kitchen waste accounts for a large proportion, and there is still a lack of rational utilization.
