Problems solved by technology

Landfill occupies land resources; due to the high moisture content in domestic waste, the incineration calorific value is low, and the safety hazards in the incineration process are high
In order to solve the problems of long transportation distance, high processing cost, heavy pollution, and the need for a large amount of manual screening, the present invention develops and designs an automatic technical method for on-site processing of domestic waste. The electromagnetic field heating principle of the chemical screening acts evenly on the mixed domestic garbage, so that it can transform and decompose the organic matter at a low temperature. Reduction

Embodiment 1

[0020] An in-situ low-temperature automatic processing technology for urban and rural mixed domestic garbage, which adopts continuous adding of urban and rural mixed domestic garbage, uses a vibrating screen to sort the mixed domestic garbage according to viscosity, weight, and size, and secondly screens non-ferrous metals through a magnetic field to separate organic waste. The material is transported to the magnetic pulse mineralization mixed domestic waste treatment device for terminal treatment, thereby realizing the efficient reduction and harmlessness of the organic matter in the mixed domestic waste, and effectively removing the pollution of the organic waste to the environment. The steps are as follows:

[0021] 1) Use the grapple to put mixed urban and rural organic solid waste (kitchen waste, fruit and vegetable waste, waste paper, packaging boxes, plastic products, glass products, dust) into the vibrating screen. Using the small amplitude and high frequency of the vibr...

Abstract

The invention provides an in-situ low-temperature automatic treatment technology for urban and rural mixed household garbage. The urban and rural mixed household garbage is continuously added, and enters a magnetic pulse reactor after being automatically sorted, and organic substances in the mixed household garbage are efficiently reduced and harmless through an electromagnetic heating treatment technology, so that daily production and daily cleaning of the urban and rural mixed household garbage can be effectively realized, and in-situ treatment is realized. The in-situ low-temperature automatic treatment technology has the advantages that the treatment technology has the characteristics of simple process, easiness in operation, unattended operation, harmless organic waste, high reductionspeed, good effect, standard emission of generated waste gas after treatment, no generation of dioxin and the like, and the whole treatment process has no secondary pollution to the environment and has remarkable economic, social and environmental benefits.

Description

technical field [0001] The invention relates to a method for low-temperature processing of mixed domestic garbage, in particular to a low-temperature automatic on-site processing technology for urban and rural mixed domestic garbage. Background technique [0002] Household waste is difficult-to-use substances produced in the process of human life, mainly including kitchen waste, fruit and vegetable waste, waste paper, packaging boxes, plastic products, wood products, metal products, glass products, dust and so on. Although we have established garbage sorting, for remote villages, the villagers have a low level of knowledge and it is difficult to carry out garbage sorting. At the same time, the garbage transportation distance in these areas is long, resulting in high costs and pollution during transportation. It also created a serious financial burden. [0003] The existing garbage disposal methods include landfill, incineration and other methods. Landfill occupies land res...
