Problems solved by technology

However, the incineration method requires a large investment in treatment facilities and high treatment costs. The incineration of organic pollutants in the treatment process is likely to generate highly toxic substances such as dioxins, and the purification effect of municipal sludge is not good, causing great pollution to the environment.

Abstract

The invention discloses an organic solid waste microwave pyrolysis process and device. The device comprises a sludge powder bin, a 1# screw conveyor, a sludge microwave multi-hearth furnace, a 2# screw conveyor, a Raymond pulverizer, a 3# screw conveyor and a gasified slag storage bin which are connected in sequence; and a plurality of layers of large circular furnace plates and small circular furnace plates which are alternately arranged are arranged on a middle shaft in the sludge microwave multi-hearth furnace, the large circular furnace plates and the small circular furnace plates rotate around the middle shaft, a scraper is arranged on each layer of circular furnace plate, a through hole is formed in the position, close to the middle shaft, of each layer of large circular furnace plate, and a plurality of microwave sources are arranged on the outer wall of the sludge microwave multi-hearth furnace. The sludge microwave multi-hearth furnace is used for treating sludge powder, so that organic matters, fixed carbon and harmful substances in the sludge powder are subjected to pyrolytic reaction, gasified and fully decomposed with inorganic oxide to obtain pyrolytic gasified slag,the content of the organic matters is greatly reduced, the quantity of the slag is also greatly reduced, and the resource utilization range is enlarged.

Description

technical field [0001] The invention relates to a microwave pyrolysis process and device for organic solid waste, belonging to the technical field of municipal sludge treatment. Background technique [0002] With the rapid development of social economy and urbanization, the amount of municipal sewage discharge and treatment in the city is increasing, and the large amount of sludge produced by municipal sewage treatment has brought new challenges to the city's environmental management. Municipal sludge contains a large number of impurities such as bacteria, viruses, insect eggs, and heavy metals. It is necessary to carry out harmless treatment of municipal sludge. The harmless treatment commonly used in the prior art is to dehydrate and dry the municipal sludge and then incinerate it directly. The incineration method can greatly reduce the volume of sludge and utilize the energy in it to increase heat utilization. However, the incineration method requires a large investment...
