Abstract

This invention relates to a wind-cooled hazardous waste incineration ash cooling device, comprising a housing. The interior of the housing is divided into a cooling zone and a settling zone. The cooling zone includes a cooling trough, which is fixedly connected to the inner wall of the housing. A cooling fan is installed on one side of the cooling trough and is connected to a first motor. An exhaust gas treatment mechanism and a circulation pump are installed on the top of the outer side of the housing. A gate mechanism is installed on one side of the housing. This invention cools the ash by installing a cooling trough and a cooling fan inside the housing, along with a circulation pump, allowing the cooling fan and water to cool the ash simultaneously. An ash filter screen and a spiral pusher are installed in the settling zone inside the housing to separate the cooled ash into solid and water. The solid-water separation is achieved through the ash filter screen and the spiral pusher, and the water after separation and settling is reused using the circulation pump. By combining wind-cooling and water-cooling methods, the amount of water used is reduced, and a water cycle is formed, avoiding excessive waste of water resources.

[0049] The utility model is further described in conjunction with the following embodiments.

[0050] Example 1.

[0051] like Figure 1-4 As shown, an air-cooled hazardous waste incineration ash cooling device includes a box body 1. The interior of the box body 1 is divided into a cooling zone 2 and a sedimentation zone 3. The cooling zone 2 includes a cooling trough 7. The cooling trough 7 is fixedly connected to the inner wall of the box body 1. A cooling fan 10 is installed on one side of the cooling trough 7. The cooling fan 10 is connected to a first motor 12. An exhaust gas treatment mechanism 8 and a circulating pump 25 are installed on the outer top of the box body 1. A gate mechanism 9 is installed on one side of the box body 1.

[0052] A spiral push rod 5 is installed on the upper side of the sedimentation area 3, and a layer of ash filter screen 4 is installed below the spiral push rod 5. Below the ash filter screen 4 is a sedimentation tank 13. The water channel on one side of the sedimentation tank 13 is connected to the water inlet pipe of the circulation pump 25. A sewage outlet 14 is opened on the other side of the sedimentation tank 13. The sewage outlet 14 is connected to the twin-screw pump 15. The outlet pipe of the circulation pump 25 passes through the top of the box and is inserted into the cooling tank 7.

[0053] The ash enters the box body 1 from the feed port 21 and falls into the cooling tank 7. The first motor 12 drives the refrigeration fan 10, and the circulating pump 25 pumps water into the cooling tank 7. The air cooling combined with the water cooling allows the ash to be cooled quickly. The cooled ash is separated from the solid by the spiral push rod 5 and the ash filter 4. The filtered water is cooled again by the circulating pump 25 after sedimentation, thereby achieving rapid and uniform cooling of the ash and saving of water resources.

[0054] When the amount of water pumped by the circulation pump 25 decreases, it means that the flocculent ash generated by sedimentation has accumulated to the point where it blocks the water inlet pipe of the circulation pump 25. At this time, the twin-screw pump 15 can be used to pump the flocculent ash out of the sedimentation tank 13.

[0055] A feed port 21 is provided on the top of the box body 1, and the feed port 21 is funnel-shaped. An electric valve 22 is installed on the feed port 21. A slag outlet 23 is provided on the other side of the box body 1, and a slag outlet hopper 24 is fixedly installed at the bottom of the slag outlet 23. The electric valve 22 is a prior art and will not be described in detail.

[0056] The gate mechanism 9 includes a gate 91, a rack groove 92 is opened in the middle of the gate 91, two sliding grooves 93 are installed on the gate 91, a lifting motor 94 is installed on the upper side of the gate 91 of the box body 1, and a gear 95 is installed on the output shaft of the lifting motor 94. The gear 95 engages with the rack groove 92, and two positioning guide rails 96 are installed on the other side of the box body 1.

[0057] The lifting motor 94 on the box body 1 drives the gear 95 on the output shaft to rotate, and the sliding groove 93 is correspondingly connected to the positioning guide rail 96. Since the gear 95 engages the rack groove 92, the gear 95 rotates to move the gate 91 along the two positioning guide rails 96. The lifting motor 94 controls the lifting and lowering of the gate 91, and the size of the slag outlet 23 can be adjusted to control the slag discharge speed.

[0058] The exhaust gas treatment mechanism 8 includes an air exchange pump 81, the air inlet end of the air exchange pump 81 is connected to the box body 1, and the air outlet end of the air exchange pump 81 is connected to the treatment box 82. A catalyst layer 83 and an activated carbon layer 84 are installed inside the treatment box 82, and an air outlet 85 and a liquid outlet 86 are opened on the side of the treatment box 82.

[0059] The exhaust gas generated in the box body 1 enters the interior of the treatment box 82 through the ventilation pump 81 for preliminary treatment. The exhaust gas will produce a catalytic reaction when passing through the catalyst layer 83. The gas after the catalytic reaction passes through the activated carbon layer 84 to adsorb the solids in the gas. Finally, the gas and liquid are discharged from the treatment box 82 through the gas outlet 85 and the liquid outlet 86 respectively.

[0060] A filter frame 16 is installed on one side of the ash filter 4, a handle 18 is installed on the filter frame 16, the filter frame 16 is slidably connected to a limiting block 19, a limiting groove 20 is provided on the box body 1, and a filter groove 17 is installed on the inner wall of the box body 1.

[0061] The ash filter 4 is inserted into the filter groove 17, and the handle 18 on the filter frame 16 is used to disassemble and assemble the ash filter 4. One end of the filter frame 16 is connected to the limit block 19 through a slide groove rail. By moving the limit block 19, the limit groove 20 is inserted or pulled out to fix or disassemble the filter frame 16, thereby realizing quick disassembly and assembly of the ash filter 4 and facilitating cleaning.

[0062] The utility model installs a cooling tank 7 and a cooling fan 10 inside a box body 1, and simultaneously provides a circulating pump 25, so that the cooling fan 10 and water cool the ash at the same time, installs an ash filter 4 and a screw push rod 5 in the internal sedimentation area 3 of the box body 1, separates the solid from the water in the cooled ash, installs a gate mechanism 9 to reduce manpower input, and provides an exhaust gas treatment mechanism 8 to preliminarily treat the generated exhaust gas, separates the solid from the water through the ash filter 4 and the screw push rod 5, and then uses the circulating pump 25 to reuse the water resources after separation and sedimentation, and at the same time combines the cooling methods of air cooling and water cooling to reduce the use of water resources, and constitutes a water cycle to avoid excessive waste of water resources.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
