Solid hazardous waste treating system

Abstract

The invention discloses a solid hazardous waste treating system. The harmless resourceful treating system at least comprises a waste collection cavity, a heat exchanger, a carbonization furnace, a combustion chamber, a reaction chamber and a sprinkling chamber. By arranging a solid particle smashing machine, it is ensured that waste is evenly and stably preheated in the preheating process in the heat exchanger. Meanwhile, the carbonization efficiency of waste in the carbonization furnace is improved, and the condition that carbonization is not thorough since material blocks are too large is avoided. Meanwhile, by arranging the reaction chamber and the sprinkling chamber in a tail gas treating part in the system, tail gas produced by the combustion chamber can be harmlessly treated to the largest maximum, sulfide, nitride and carbon oxide in tail gas produced through combustion can be recycled in an acid liquor mode, and the environmental pollution caused when tail gas is exhaust into atmosphere through a traditional technology is avoided.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to a solid hazardous waste treatment system. Background technique [0002] 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. The organic waste is generated in various stages of the treatment process of urban organic waste (such as urban sewage). Organic waste contains a large number of bacteria and parasites, and its biochemical properties are very unstable, which makes it a big prob...

Problems solved by technology

[0002] 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

Direct landfilling will cause a large amount of organic waste pollutants to enter the deep layer from the surface with leachate, and even threaten groundwater and rivers, lakes and seas.

Because organic waste is rich in microorganisms, pathogens, viruses, etc., there are also great hidden dangers in the use of organic waste in agriculture. Unsanitary organic waste entering farmland and even vegetable fields may directly threaten the human food chain, thereby affecting human health. cause harm

[0003] In recent years, people have been exploring efficient, energy-saving, and harmless methods of treating organic waste. The organic waste cracking and carbonization system can convert organic waste into usable products. However, its heat utilization efficiency is low, and organic waste Low cracking speed and imperfect tail gas treatment
