Problems solved by technology

The efficiency of this method is relatively low, and the result is that the temperature rise rate in the pyrolysis reactor is also relatively low
The above-mentioned patents lead to insufficient thermal cracking of municipal solid waste because the thermal cracking reactor and the combustion chamber are in a separate state, and the treatment method is not satisfactory.

Embodiment 1

[0008] Embodiment 1: refer to figure 1In this embodiment, the municipal solid waste transported from the garbage dump is pulverized by a pulverizer and then enters the feed bin, and then enters the thermal cracking reactor from the still head supporting the thermal cracking reactor through the garbage dehydrator. The motor is connected with the driven gear through the driving gear to drive the thermal cracking reactor to rotate. The thermal cracking reactor is placed in the combustion chamber, the outer diameter of the thermal cracking reactor is dynamically fitted and connected to the combustion chamber, and a gas burner is arranged in the combustion chamber. Municipal solid waste is evenly heated and fully cracked in the thermal cracking reactor. The cracked gas enters the quenching, separation and purification device from the reactor head 3, and light bio-oil, heavy Bio-oil and combustible bio-gas. The combustible biogas is used by the gas burner installed in the combusti...

Embodiment 2

[0009] Embodiment 2: refer to figure 2 ,

[0010] (1) Pre-processing

[0011] The garbage from the garbage dump enters the silo through the shredder, and then is lifted into the dehydrator. The size of the pulverized municipal solid waste is 10-100 mm, preferably 30-50 mm; if the size is too small, it is easy to form a paste, which is not convenient for subsequent transportation, and the size as small as possible is convenient for heat transfer inside the municipal solid waste.

[0012] (2) Thermal cracking treatment

[0013] Use the cracked gas or liquefied petroleum gas stored in the early stage to burn and heat the pyrolysis reactor through the gas burner installed in the combustion chamber, so that the entire pyrolysis reactor is evenly heated at a high temperature, and the municipal solid waste from the dehydrator enters the combustion chamber The middle-rotating thermal cracking reactor is fully heated and cracked to achieve a high-efficiency heat conduction state. ...

Abstract

The invention relates to the technical field of urban household garbage harmless treatment, in particular to an urban household garbage thermal cracking treatment device and a method for conducting urban household garbage thermal cracking with the same. The urban household garbage thermal cracking treatment device mainly comprises a thermal cracking reaction kettle and a combustion chamber, the combustion chamber is internally provided with fuel gas nozzles, kettle heads bear the thermal cracking reaction kettle, the thermal cracking reaction kettle is connected with a motor through a transmission mechanism, and the outer diameter of the thermal cracking reaction kettle is in movable fit connection with the combustion chamber. The method for conducting urban household garbage thermal cracking mainly includes the steps of pretreatment, thermal cracking treatment, separation and recycling utilization and secondary pollutant treatment. The thermal cracking reaction kettle is arranged in the combustion chamber, so that the whole thermal cracking reaction kettle is heated evenly, a high-efficiency thermal conduction state is reached, meanwhile reasonable thermal cracking parameters are selected, full cracking is conducted on urban household garbage, and generation of dioxin is effectively inhibited and completely eradicated.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of municipal solid waste, in particular to a thermal cracking treatment device for municipal solid waste and a method for thermally cracking municipal solid waste using the treatment device. Background technique [0002] At present, there are three reliable disposal methods for municipal solid waste, namely sanitary landfill, incineration for power generation and composting. Sanitary landfill has low investment, but it has the possibility of air pollution, soil pollution, surface water pollution and groundwater pollution. It occupies a large area and it is difficult to select a site. In some large and medium-sized cities, a polyethylene diaphragm is used to prevent seepage at the bottom of the landfill, and the garbage is compacted and then covered with a film, and there are collection and treatment of leachate, landfill gas, prevention and control Set of measures for soil pollution. ...
