Abstract

The invention relates to a treatment system and method for domestic waste. The treatment system comprises a pretreatment device, a revolving bed pyrolyzing furnace, an organic waste hydrolyzing device and an oil gas direct-burning boiler, wherein the pretreatment device comprises a waste inlet, a combustible outlet and an organic compound outlet; the revolving bed pyrolyzing furnace comprises a pyrolyzing raw material inlet, a high-temperature oil gas outlet and a pyrolytic carbon outlet; the pyrolyzing raw material inlet is connected with the combustible outlet of the pretreatment device; the organic waste hydrolyzing device comprises an organic compound inlet and a hydrolysate outlet; the organic compound inlet is connected with the organic compound outlet of the pretreatment device; the oil gas direct-burning boiler comprises a high-temperature oil gas inlet and a superheated steam outlet; and the high-temperature oil gas inlet is connected with the superheated steam outlet of the revolving bed pyrolyzing furnace. According to the treatment system disclosed by the invention, the reducing effect of waste pyrolyzing can be sufficiently achieved, the innocuity and reducing of combustible components are realized, and degradable organic compounds can be treated by a hydrolyzing method; and various waste treatment techniques are combined, so that the purpose that the domestic waste is thoroughly and effectively treated is realized.

Description

technical field [0001] The invention mainly relates to the field of domestic waste treatment, in particular to a system and method for domestic waste treatment. Background technique [0002] With the acceleration of economic and urbanization, the continuous growth of population and the continuous improvement of living standards, my country's energy consumption is huge, and the amount of domestic waste is also increasing rapidly. At present, 2 / 3 of the big cities are facing the dilemma of garbage siege. Through technical means It is a very important topic to turn domestic garbage into usable resources and alleviate the energy and environmental crisis in our country. Municipal solid waste has a wide range of sources and complex components, which brings great difficulties to waste disposal. [0003] Domestic waste pyrolysis technology is more and more favored by people because of its high resource utilization rate and low environmental pollution. The main products after pyroly...
