Urban and rural mixed household garbage in-situ low-temperature integrated treatment device and application

Abstract

The invention provides an urban and rural mixed household garbage in-situ low-temperature integrated treatment device. The device consists of a vibration screening and crushing system, a magnetic separator, a conveying belt, a magnetic pulse mineralization reactor and a tail gas purifying device. The device adopts continuous feeding of urban and rural mixed household garbage, uses a vibration screen for mixing the household garbage to sort according to viscosity, weight and size, screens nonferrous metal through a magnetic field, conveys organic substances to the magnetic pulse mineralizationmixed household garbage treatment device for terminal treatment, realizes efficient reduction and harmlessness of the organic substances in the mixed household garbage, and effectively removes environmental pollution by organic wastes. The treatment device has such characteristics as simple process, easy operation, unattended operation, harmlessness of the organic wastes, fast reduction speed, good effect, standard emission of generated waste gas after treatment and no generation of dioxin; and the whole treatment process has no secondary environmental pollution, and achieves prominent economic, social and environmental benefits.

Description

technical field [0001] The invention relates to a low-temperature treatment method for mixed domestic garbage, in particular to an on-site low-temperature integrated treatment device for urban and rural mixed domestic garbage and its application. 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 occu...

AI Technical Summary

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 on-site low-temperature integrated processing device for urban and rural mixed domestic waste and its application. The method utilizes the properties of domestic waste Features, the principle of electromagnetic field heating based on integrated screening acts evenly on mixed domestic waste, making it transform and decompose organic matter at low temperature, with the characteristics of fast, efficient, low temperature, unattended, etc., thus realizing the high efficiency of domestic waste detoxification and reduction
