Abstract

An organic waste low-temperature in-situ degradation reaction device is composed of a magnetic pulse reactor, a rotation device, a temperature measuring device, a humidity measuring device and a watersupplementing device. Heat is generated through electromagnetic conversion for heat decomposition of organic matter at the temperature ranging from 150 DEG C to 180 DEG C, and kitchen waste, straw, garden greening garbage, rice bran, grass or wheat bran and other organic waste can be converted into carbon dioxide, water, inorganic mineral substances and the like within 16-24 h. The organic wastelow-temperature in-situ degradation reaction device has the advantages that the reaction device has the characteristics of being low in energy consumption and cost, small in occupied area, easy to operate, safe and reliable; under periodic stirring of a stirring device, sufficient stirring of materials can be achieved, sufficient contact with oxygen is achieved, incomplete reaction is avoided, andgeneration of carbon monoxide is effectively reduced; according to the device, through accurate thermocouple temperature control and in combination with the magnetic pulse technology, energy consumption is greatly reduced; and through reaction conditions, generation of dioxin is effectively restrained, meanwhile, the reaction speed is increased through material disturbance, and the organic matterdegrading efficiency can reach 80% or above.

Description

technical field [0001] The invention relates to low-temperature in-situ pyrolysis treatment technology for organic waste, in particular to a low-temperature in-situ degradation reaction device for organic waste and its application. Background technique [0002] With the development of the times and the improvement of people's living standards, the pace of urban construction has accelerated, and the people's growing consumption demand and desire for a beautiful city have become stronger and stronger, resulting in a large amount of urban garbage and domestic garbage. Among them, organic waste accounts for more than 70%, which occupies a large amount of land resources and environmental capacity, seriously affecting the rapid development of economy and society. Landfill and incineration are the current mainstream treatment methods. Landfill occupies land resources and the long-term anaerobic process will continue to release biogas and produce leachate, which not only pollutes s...
