Problems solved by technology

[0003] The purpose of the present invention is to address the deficiencies of the existing solid waste pyrolysis technology, to provide a device and method for the harmless treatment of solid waste, to solve the problem of poor gas quality and low calorific value, incomplete combustion of gas, and tail gas after gasification of solid waste. Key technical issues such as emission not up to standard and harmful flue gas remaining from gasification equipment must be discharged

Embodiment 1

[0025] see figure 1 , the solid waste harmless treatment device includes a solid waste pyrolysis gasification furnace 1, a gas oxygen distribution premixed filter chamber 3, a gas combustion chamber 7, a dechlorination and desulfurization drying device 20, and a solid waste pretreatment device connected in sequence The solid waste harmless treatment device also includes a biomass pyrolysis gasifier 2 communicated with the gas oxygen distribution premixed filter chamber 3, and a tail gas treatment device communicated with the top of the dechlorination and desulfurization drying device 20; the gas The filter chamber in the oxygen distribution premixing filter chamber 3 is provided with a filter screen; the gas combustion chamber 7 is provided with a cylindrical metal fiber burner 8 with an open end, and the diesel pipe 10 and the igniter 11 extend into the cylindrical metal fiber burner 8. Inside the fiber burner 8; the gas combustion chamber 7 is also provided with a planar or ...

Embodiment 2

[0031] Based on the solid waste harmless treatment method of the solid waste harmless treatment device described in embodiment 1, the steps are as follows:

[0032] (1) After the solid waste is broken through the wire rope bag breaking machine to break plastic bags, woven bags, and cloth bags, it is sent to the vibrating screen to remove large non-combustible materials, and then sent to the magnetic separator to remove metal substances, and then sent to the crushing and crushing machine into lumps below 30cm, and then sent to the drum sieve to screen out small granular non-combustibles, and then sent to the crawler-type rolling dehydrator to squeeze out the internal moisture of the organic matter, so that the moisture content of the solid waste is reduced from more than 45%. After reaching below 30%, it is sent to the dechlorination and desulfurization drying device;

[0033] (2) The solid waste is in full contact with the hot air sent from the gas combustion chamber in the de...

Abstract

The invention discloses a solid waste innocent treatment device and a solid waste innocent treatment method. The solid waste innocent treatment device comprises a solid waste pyrolysis gasifier, a fuel gas oxygen replenishment premixing and filtering chamber, a fuel gas combustion chamber, a dechloridation and desulfurization drying device and a solid waste pretreatment device which are sequentially communicated; the solid waste innocent treatment device also comprises a biomass pyrolysis gasifier and a tail gas treatment device, wherein the biomass pyrolysis gasifier is communicated with the fuel gas oxygen replenishment premixing and filtering chamber; the tail gas treatment device is communicated with the top of the dechloridation and desulfurization drying device. When the method and the device are used for treating solid waste, the content of Dioxin in a detected emitted tail gas is lower than 0.023ng / m<3>, and the emission allowances of other gases, such as CO, SO2, HC1 and NOx, are also highly superior to the emission standard (GB18485-2014) issued by the nation in July 1st, 2014, and can completely meet the requirement of environment-friendliness.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a solid waste harmless treatment device and method. Background technique [0002] Solid waste includes: industrial waste, medical waste, domestic sludge, domestic waste, etc. The treatment of solid waste, except medical waste, has been initially treated in an environmentally friendly manner, and the remaining industrial waste, domestic sludge, and domestic waste have not yet been processed. Environmentally friendly disposal, most of the current implementation methods are still landfill, the groundwater pollution and surrounding environmental pollution caused by landfill are very serious, which will cause great harm to the lives of local residents. Another treatment method is incineration. Incineration will produce a large amount of harmful and toxic smoke and particulate matter, especially the well-known emission of dioxins, which makes people turn pa...
