Problems solved by technology

[0003] The existing waste treatment technologies at home and abroad mainly include landfill method, composting method, and incineration method. Due to the certain application limitations of each technology, there is a risk of secondary pollution, and the resource recovery rate in the treatment process is relatively low. Imperfection makes its recovery benefit not obvious
[0005] (1) Industrialized municipal solid waste pyrolysis devices all adopt "external heating" heating method, and the energy consumption of the process is relatively high
[0006] (2) Since the operating temperature of the external thermal waste pyrolysis is 600-1000°C, the pyrolysis environment cannot achieve high reducing atmosphere conditions, and there are risks of NOx and dioxin pollution
[0007] (3) Due to the external heating, the utilization of the pyrolysis product is poor, the level of resource utilization is low, and the recovery benefit is not obvious

Abstract

The invention provides a continuous reductive atmospheric microwave heating low-temperature cracking furnace structure for urban domestic garbage, which fulfills the purposes of improving the cracking efficiency, promoting the resource utilization level of garbage cracking reclamation substances, and realizing hazard-free treatment. The low-temperature cracking furnace consists of a feeding and garbage gas displacement mechanism arranged on a main body cylinder in a main body part, a garbage preheating and cracking vapor delivery chamber, a garbage water evaporation and heating chamber, a main garbage cracking chamber, a cracking material carbonization chamber, a carbonized material collecting chamber and a carbonized material collecting mechanism. The low-temperature cracking furnace has the advantages of continuously treating the garbage, consuming low energy, having minimum dust discharge amount, particularly avoiding the risks of generating NOx and dioxin, and basically reaching zero emission of the generated NOx and dioxin.

Description

technical field [0001] The invention belongs to the treatment of urban living garbage in the technical field of environmental protection, and in particular relates to a continuous reducing atmosphere microwave heating low-temperature cracking furnace structure for urban living garbage. Background technique: [0002] 1. Status quo of garbage cracking technology: [0003] The existing waste treatment technologies at home and abroad mainly include landfill method, composting method, and incineration method. Due to the certain application limitations of each technology, there is a risk of secondary pollution, and the resource recovery rate in the treatment process is relatively low. Imperfection causes its recycling benefit to be inconspicuous. Due to its high level of resource utilization and low secondary pollution, waste pyrolysis technology has become one of the main development directions of waste treatment technology. [0004] The existing garbage cracking technology mai...
