Description

Technical Field

[0001] This utility model relates to the field of dust collection technology, specifically a coal combustion dust collection and treatment device. Background Technology

[0002] my country currently has over 600,000 scattered coal-fired boilers and kilns, consuming over 40 billion tons of raw coal annually, generating significant dust pollution. Dust is a major factor inducing respiratory diseases (such as pneumoconiosis), and long-term exposure harms workers' health. Particulate matter (PM2.5 / PM10) can lead to reduced visibility, acid rain, and other environmental problems.

[0003] Existing devices can only filter dust in hot air streams, but cannot collect it. Since coal combustion dust can be reused, it needs to be collected. Furthermore, filtering dust from the gas requires a large amount of water for spraying, resulting in a high water demand. Therefore, we propose a coal combustion dust collection and treatment device. Utility Model Content

An output pipe is fixedly connected to the output end of the water pump. The output pipe extends into the treatment box and is fixedly connected to a nozzle. The nozzle has several spray holes at its tip. When gas needs to be treated and collected, water is sprayed from the nozzle to adhere the dust carried in the gas, thus leaving the dust in the dust collection box. Through this process, the device can collect and treat gas.

[0006] Preferably, a spray cylinder is fixedly installed on the top of the treatment box, an air inlet is fixedly connected to the top of the spray cylinder, and an air outlet is fixedly installed on the top of the treatment box. When treating gas, the gas is fed into the spray cylinder through the air inlet, thereby treating the gas. Finally, the treated gas is discharged from the air outlet.

[0007] Preferably, a water injection pipe is fixedly connected to one side of the treatment tank, and a first valve is rotatably connected to the outside of the water injection pipe. A drain pipe is fixedly connected to the bottom of the water collection tank, and a second valve is rotatably connected to the outside of the drain pipe. Water can be injected into the water collection tank using the water injection pipe, and water can be drained from the water collection tank using the drain pipe.

[0008] Preferably, an observation window is fixedly installed on one side of the processing box, and a control panel is fixedly installed on one side of the processing box.

[0009] Preferably, four support legs are fixedly installed at the bottom of the processing box, and a support plate is fixedly installed at the bottom of each of the four support legs.

[0012] This utility model provides a coal combustion dust collection and treatment device, which has the following beneficial effects:

[0013] 1. This coal combustion dust collection and treatment device, through the setting of dust collection box and filter plate, allows the sprayed gas to pass through the filter plate to filter out the dust, and leaves the dust in the dust collection box. Through this process, the device can not only filter the dust in the gas, but also collect the filtered dust by pulling out the dust collection box, so that the collected dust can be reused.

[0014] 2. This coal combustion dust collection and treatment device, through the setting of output and input pipes, allows water after spraying the gas to fall into the water collection tank, and then be recycled by a water pump. This process can reduce water consumption and lower treatment costs. Attached Figure Description

A partition 10 is fixedly installed inside the treatment box 1. Slide grooves 101 are opened on both sides of the treatment box 1 that are close to each other. Slide plates 9 are slidably connected inside the two slide grooves 101. A dust collection box 6 is fixedly installed between the two slide plates 9. The dust collection box 6 is used to collect dust in the gas. A filter plate 7 is fixedly installed at the bottom of the dust collection box 6. The filter plate 7 is used to filter dust in the water. A water collection tank 2 is fixedly installed at the bottom of the treatment box 1. The water collection tank 2 is used to hold water. An input pipe 15 is fixedly connected to one side of the water collection tank 2. The other end of the input pipe 15 is fixedly connected to the input end of the water pump 11. An output pipe 12 is fixedly connected to the output end of the water pump 11. The output pipe 12 extends into the treatment box 1 and is fixedly connected to a nozzle 13. The nozzle 13 is used to spray water. Several spray holes 14 are provided at the top of the nozzle 13.

[0023] like Figure 2 As shown, a spray cylinder 3 is fixedly installed on the top of the treatment box 1. The spray cylinder 3 is used to spray the gas. An air inlet 4 is fixedly connected to the top of the spray cylinder 3. The air inlet 4 is used to input the gas into the spray cylinder 3. An air outlet 5 is fixedly installed on the top of the treatment box 1.

[0024] like Figure 1 As shown, a water injection pipe 17 is fixedly connected to one side of the treatment tank 1, and a first valve 18 is rotatably connected to the outside of the water injection pipe 17. The first valve 18 is used to control the water injection pipe 17. A drain pipe 22 is fixedly connected to the bottom of the water collection tank 2, and a second valve 23 is rotatably connected to the outside of the drain pipe 22. The second valve 23 is used to control the drain pipe 22.

[0025] like Figure 1 As shown, an observation window 16 is fixedly installed on one side of the processing box 1. The observation window 16 is used to observe the inside of the device. A control panel 21 is fixedly installed on one side of the processing box 1. The control panel 21 is used to control the device.

[0026] like Figure 3 As shown, four support legs 19 are fixedly installed at the bottom of the processing box 1, and support plates 20 are fixedly installed at the bottom of each of the four support legs 19. The support legs 19 and support plates 20 are used to support the device.

[0027] like Figure 2 As shown, a handle 8 is fixedly installed on one side of the dust collection box 6, and the handle 8 is used to pull out the dust collection box 6.

[0028] like Figure 1 As shown, the water pump 11 is electrically connected to the control panel 21.

[0029] In summary, when using this coal combustion dust collection and treatment device, firstly, open the first valve 18, then inject an appropriate amount of water into the water collection tank 2 through the water injection pipe 17.

Then, use the control panel 21 to turn on the water pump 11. At this time, the water pump 11 will draw water from the water collection tank 2 into the input pipe 15, and then the water will pass through the output pipe 12 and the nozzle 13 in sequence, and finally be sprayed out from the spray hole 14. The water will then spray the gas, and the sprayed water will carry the dust in the gas through the filter plate 7. After passing through the filter plate 7, the water will fall into the water collection tank 2. Through the action of the filter plate 7, the dust can be filtered, and the filtered dust is left in the dust collection box 6. The water inside the tank 2 sprays the gas for a long time, which reduces the adhesion of water to dust. Therefore, the first valve 18 can be opened to inject a wetting agent into the water injection pipe 17, thereby increasing the adhesion of water to dust. The treated gas will be discharged from the air outlet 5. After the treatment is completed, the dust inside the dust collection box 6 can be viewed through the observation window 16. The water pump 11 can be stopped using the control panel 21. Then, the operator can use the handle 8 to pull out the dust collection box 6 and dry the dust inside the dust collection box 6. After drying, the dust is collected and placed in a designated location. The filter plate 7 is then rinsed and can be reused. After the dust is collected, the dust collection box 6 is put back in place using the cooperation of the slide 101 and the slide plate 9. Then, the second valve 23 is opened to discharge the sewage inside the water collection tank 2 from the drain pipe 22. The above is the working principle of this utility model.
