Description

Technical Field

[0001] The utility model relates to the field of cooling, and more specifically, to a slag cooling device for recycling domestic incinerated garbage. Background Art

[0002] Domestic incineration waste refers to a method of treating solid waste generated in daily life (including but not limited to dry waste, kitchen waste, other non-recyclable waste, etc.) through professional domestic waste incineration facilities under a strictly controlled high-temperature environment for pyrolysis and combustion. After the incineration treatment, some parts that cannot be pyrolyzed will form slag. These slags contain some recyclable metals, sand and gravel, etc., and some toxic and harmful substances will also remain. Since the temperature of the slag after incineration is relatively high, the slag needs to be cooled before the metal, sand and gravel residues can be extracted and recycled.

[0003] Commonly used ash cooling methods include natural cooling, air cooling and water cooling. Natural cooling is time-consuming and has low production efficiency. Air cooling has poor cooling effect on stacked slag, and the slag needs to be spread out, which has high requirements for site and equipment, and toxic and harmful substances are easily spread during the air cooling process. Water cooling has high cooling efficiency, but after cooling, the toxic and harmful substances in the slag will contaminate the cooling water, and the cooling water needs to be purified later.

[0004] Based on the above, the purpose of the utility model is to provide a slag cooling device for recycling domestic incinerated waste to solve the above problems. Utility Model Content

The cooling box and the cooling column reduce the temperature of the ash through the flowing cold water, and then a stirring structure is arranged to stir the ash to make the ash cooler more evenly, and fly ash and fine particles attached to recyclable materials such as metals and sand and gravel are knocked off. Then a purification module is arranged to purify the fly ash and toxic and harmful gases, and an atomizing nozzle is arranged to allow fine particles to adsorb each other for easy subsequent treatment.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a slag cooling device for recycling domestic incineration waste, comprising a cooling box, the cooling box is provided with a feed port, a discharge port and a cooling column, the inner wall of the cooling box and the cooling column are provided with flow grooves for the flow of coolant, the cooling box is provided with a plurality of filter plates 1 that are separated and arranged, the cooling box is provided with screening outlets corresponding to the number and position of the filter plates 1, the discharge port and the screening outlet are provided with door panels, the cooling column is rotatably connected with a mounting frame, the mounting frame is fixedly connected with a plurality of stirring rods, the cooling box is provided with a driving mechanism for driving the mounting frame to rotate, the upper end of the inner cavity of the cooling box is provided with a purification module for purifying toxic and harmful substances, and the lower end of the inner cavity of the cooling box is provided with a plurality of atomizing nozzles.

In this process, the atomizing nozzle will spray water mist on the fallen bottom ash and fine particles, so that the bottom ash and fine particles are adsorbed on each other for subsequent processing. With this arrangement, the cooling mechanism can cool the ash, and can also screen the recyclable materials and toxic and harmful substances in the ash and collect and treat the toxic and harmful substances to prevent the spread of toxic and harmful substances, and will not pollute water sources or harm the health of workers, making the cooling device more comprehensive.

[0022] Further: the purification module includes a dust hood 12 fixedly connected to the cooling box, the dust hood 12 is provided with a filter box 13 fixedly connected and conducted thereto, a plurality of filter plates 14 are detachably connected in the filter box 13, the filter plate 2 is a bamboo charcoal fiber filter plate, a purification tank 15 is installed on the cooling box 1, an alkaline solution (such as lime milk, caustic soda solution) is stored in the purification tank as an absorbent to react chemically with toxic and harmful gases, the filter box 13 is provided with a ventilation pipe 16 with one end fixedly connected thereto, the other end of the ventilation pipe 16 extends into the purification tank 15, and a fan 17 is installed on the ventilation pipe 16.

[0023] Furthermore, a plurality of scrapers 18 are fixedly connected to the mounting frame 9, and the plurality of scrapers 18 are respectively attached to the filter plate 1 6 and the bottom wall of the cooling box 1 .

[0024] Furthermore, a plurality of collision rods 19 are fixedly connected to the scraper 18, and a plurality of collision rods 20 are fixedly connected to the inner wall of the cooling box 1.

[0025] Furthermore, the driving mechanism includes a motor 21 , a driving gear 22 is fixedly connected to the output shaft of the motor 21 , and a gear ring 23 matched with the driving gear 22 is fixedly connected to the mounting frame 9 .

[0026] Furthermore: the flow channel 5 is arranged in a spiral shape.

[0027] Working principle: When slag cooling is required, the two ends of the flow trough 5 are respectively connected to the external water supply equipment and water storage equipment, and the atomizing nozzle 11 is connected to the external water supply equipment, so that the external cold water continuously passes through the flow trough 5, and then the slag is poured into the inner cavity of the cooling box 1 through the feed pipe on the feed port 2, and then the cover on the feed pipe is closed. The flowing cold water will exchange heat with the slag through the cooling column 4 and the inner wall of the cooling box 1.

The filtered gas is then sent to the purification tank 15 to react with chemical reagents to further eliminate toxic and harmful substances in the gas.

[0029] Several filter plates 6 will filter fine particles and bottom ash, so that larger recyclable materials such as metal and sand and gravel will remain on the surface of the filter plate 6, while the bottom ash and fine particles will fall onto the bottom wall of the inner cavity of the cooling box 1. In this process, the scraper 18 will prevent the filter holes of the filter plate 6 from being blocked, and the atomizing nozzle 11 will spray water mist on the falling bottom ash and fine particles, so that the bottom ash and fine particles are adsorbed on each other for subsequent processing. When the ash is cooled, the door panel 8 is opened to take out the metal, sand and gravel and bottom ash respectively. With this arrangement, the cooling equipment can cool the ash, screen and separate the recyclable materials from the toxic and harmful substances in the ash, collect and process the toxic and harmful substances, prevent the spread of toxic and harmful substances, and will not pollute the water source and harm the health of workers. The cooling water after absorbing the heat of the ash can also be recycled to utilize its thermal energy, making the function of the cooling equipment more comprehensive.
