Description

Technical Field

[0001] This utility model patent belongs to the technical field of solid waste treatment equipment, and specifically relates to a solid waste incineration waste residue wet slag drying treatment equipment. Background Art

[0002] At present, a small amount of waste residue will be produced after the incineration of hazardous solid waste. However, the heavy metals in the incineration residue are difficult to degrade naturally, which has a serious impact on the environment. The existing international environmental regulations classify it as hazardous waste, so companies have to pay a certain fee to treat the solid waste incineration residue. The slag after the incineration of solid hazardous waste cannot be transported directly due to its high temperature. It is usually discharged into the water of the cooling pool for cooling, and then scooped out by a slag scooping machine, transported out of the site by a conveyor belt, and handed over to relevant units for subsequent treatment.

[0003] The existing wet slag from the incineration of solid hazardous waste is taken out of the water and placed on a conveyor belt for transportation. This will cause water marks everywhere on the transportation site, affecting the surrounding environment. At the same time, because the waste residue treatment is charged by weight, the direct treatment of the wet slag will relatively increase the treatment cost.

[0004] Furthermore, the wet slag drying treatment equipment for solid hazardous waste incineration slag disclosed in the current Chinese patent (CN216769955U) uses microwave heating to dry the wet slag, which is actually very inefficient. This is because the wet slag still contains a large amount of water after being fished out, so when it is placed on the conveyor belt, it will wet the conveyor belt, reducing the drying efficiency. At the same time, the wet slag fished out after being soaked in water is easy to condense into clumps, so when performing microwave drying, greater power is required, thereby increasing the processing cost.

[0005] To this end, this paper proposes a solid waste incineration waste wet slag drying treatment equipment. Utility Model Content

[0023] like Figures 1 to 4 As shown, the prior art in this embodiment has the following problems: the inventors have found that the wet slag drying treatment equipment for solid hazardous waste incineration waste residue disclosed in the current Chinese patent (CN216769955U) has a very low actual efficiency in drying the wet slag by microwave heating, because the wet slag still contains a large amount of water after being fished out, so when it is placed on the conveyor belt, it will wet the conveyor belt, reducing the drying efficiency; at the same time, the wet slag fished out after being soaked in water is easy to condense into a mass, so when performing microwave drying, a larger power is required, thereby increasing the processing cost.

[0024] Therefore, the inventor provides a solid waste incineration waste residue wet residue drying treatment equipment, including a receiving bin, a filtering and conveying device, and a drum dehumidification device. The feed port A5 of the receiving bin is arranged above the receiving end of the filtering and conveying device, the feed port B15 of the filtering and conveying device is connected to the feed end of the drum dehumidification device, and the discharge end of the drum dehumidification device is provided with a feed port C27.

[0025] The principle and effect are as follows: when the device is used, the wet residue fished out can be put into a receiving bin, and the wet residue of solid waste can be broken up and dispersed by the tearing roller group 2 in the receiving bin, and the wet residue after dispersion falls onto the filtering and conveying device, and the moisture on the wet residue is initially filtered out by the filtering and conveying device and recovered into the cooling pool, and at the same time, the filtering and conveying device conveys the waste residue to the drum dehumidification device for dehumidification by the high-temperature tail gas of the decomposition furnace; and when conveying the waste residue, the airtight material blocking component can prevent the solid waste from blocking the discharge port B15 when too much solid waste is discharged, so as to ensure that the solid waste can fall stably, and the anti-carrying brush wheel 12 can also brush off the solid waste adhered to the dehydration belt conveyor 7, and the air-locking discharge valve A14 in the airtight material blocking component can work together with the airtight valve in the discharge port C27 to prevent the leakage of high-temperature tail gas during dehumidification;

[0026] During this process, the shredding roller group 2 in the device can prevent the wet slag from agglomerating, the filtering and conveying device can initially filter out the moisture on the wet slag and recycle it, avoiding the waste of water resources, and the drum dehumidification device uses the high-temperature exhaust gas of the decomposition furnace to dehumidify the wet slag drying method, which can save energy, reasonably utilize production resources, and reduce the cost of waste slag treatment.
