Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, and particularly relates to a recycling device for realizing fly ash resource utilization by using a garbage incinerator. Background Art

[0002] The heat-treated fly ash after separation should meet the requirements of item 6.3 of the "Technical Specification for Pollution Control of Municipal Solid Waste Incineration Fly Ash (Trial)" HJ 1134-2020 (the total amount of residual dioxins should not exceed 50 ng / kg (based on the dry weight of fly ash); the leaching solution is prepared according to the method of HJ 557, and the heavy metal leaching concentration therein should not exceed the maximum allowable emission concentration limit specified in GB 8978 (the maximum allowable emission concentration of the second type of pollutants is implemented according to the first-class standard); the soluble chlorine content should not exceed 2%).

[0003] By putting granulated fly ash into the garbage incinerator, dioxins can be removed. In the existing technology, the fly ash is often fed into the incinerator through a spiral auger, which often causes the granulated fly ash to accumulate at one place in the incinerator, affecting the reaction efficiency. According to the existing technology, if the granulated fly ash is evenly fed into the incinerator, multiple augers need to be set, which will increase the cost of the equipment.

[0035] The electric slide rail 10 drives the end of the telescopic pipe 9 to reciprocate along the length direction of the material distribution tank 4 through the connecting frame 11, so that the granulated fly ash can be evenly paved in the material distribution tank 4, and the electric slide rail 10 is a prior art.

[0036] Lifting lugs 2 are arranged at the four corners of the top of the fixing frame 1. The arrangement of the lifting lugs 2 facilitates the lifting and transportation of this device.

[0037] The stirring mechanism 6 includes a mounting plate 12. The mounting plate 12 is fixed in the material distribution tank 4.
