Problems solved by technology

On the one hand, the cost of fly ash disposal is high
On the other hand, due to the unregulated market, inadequate supervision and vicious competition, the "fly ash" is in a state of "flying randomly".
If fly ash cannot be disposed of safely, it will be a great hidden danger to the environment

Embodiment Construction

[0026] Examples, see attached Figure 1~2 , a dioxin removal device for garbage fly ash, including a silo 1, a steel platform I for manual use is installed on the floor of the workshop, and the silo is equipped with a manual feeding port for initial detection and quantitative use, and the silo is a hopper structure.

[0027] The discharge opening of described silo is connected with pyrolysis furnace 2, and pyrolysis furnace is connected with nitrogen replenishment tank 3, makes in the sealing environment of nitrogen protection gas in the pyrolysis furnace; When pyrolysis furnace works, need to use nitrogen as Working under the action of protective gas, the furnace of the thermal decomposition furnace is made of stainless steel, and the effective volume in the furnace is greater than 0.8m 3 . The maximum working temperature of the pyrolysis furnace is 450°C, and the temperature of the shell of the pyrolysis furnace is less than 20°C, which is safe and reliable during operatio...

Abstract

The invention relates to a device for removing dioxin from flying garbage dust and a treatment method of the device. According to the device, the discharge hole of a cabin is communicated with a thermolysis furnace; the thermolysis furnace is communicated with a nitrogen compensating tank, so that the thermolysis furnace is in a sealed environment in the presence of the protective nitrogen gas; a cooling pipeline a with a water jacket is connected to the upper end of the thermolysis furnace; the cooling pipeline a is communicated with a cooling dust collector; a cooling pipeline b with a water jacket is communicated with the upper part of the cooling dust collector; the cooling pipeline b is communicated with a cloth belt cooling dust collector a; a conveying pipeline is communicated with the lower end of the thermolysis furnace; a feeding hole communicated with a spiral conveying cooler is communicated to the lower end of the conveying pipeline; the discharge hole in the spiral conveying cooler is communicated with a pipeline; the pipeline is communicated with a cloth belt cooling dust collector b. The device can be adopted by a user for harmless thermolysis treatment on garbage flying ash, and is large in treatment capacity, high in automation degree and energy-saving, so that an environment can be free of dust or pollution.

Description

Technical field: [0001] The invention relates to the field of garbage fly ash treatment equipment, and more specifically relates to a garbage fly ash dioxin removal device and a treatment method thereof. Background technique: [0002] Fly ash is the residue of waste incineration, and 90% of the carcinogen "dioxin" produced by waste incineration is in the fly ash. Improper handling of fly ash that has not been solidified, and a large amount of heavy metals and dioxins in it will cause serious pollution accidents and endanger the health of residents. Only a few cities across the country are dealing with waste incineration fly ash. On the one hand, the cost of fly ash disposal is very high. On the other hand, due to the unregulated market, insufficient supervision and vicious competition, the "fly ash" is in a state of "flying randomly". If fly ash cannot be safely disposed of, it will be a great hidden danger to the environment. Invention content: [0003] The purpose of...
