Description

Technical Field

[0001] The invention relates to the field of industrial smoke removal, and in particular to an industrial smoke treatment device based on a graded treatment technology. Background Art

[0002] Industrial smoke is a mixture of fine particles, gases, liquids, etc. generated by various industrial production activities. It is extremely harmful and requires a series of purification operations before it is discharged.

[0003] In practice, different purification methods should be selected according to the continuous industrial smoke and particle size, emission standards and process flow. The dry collection method of industrial smoke uses the filter layer to capture and collect the dust multiple times. In a dry environment, when the filter layer and dust collection are replaced, it will cause secondary pollution to the environment. If the filter layer is not replaced in time, the dust collected on the filter surface will reduce the ventilation area of ​​the filter, which will limit the emission of industrial smoke. The wet treatment method of industrial smoke is to flush or spray the exhaust gas so that the smoke particles come into contact with water and are captured to achieve the purpose of purifying the air. Although the wet treatment method can reduce the harm of smoke to the environment and human body to a certain extent, it requires a large amount of water to capture smoke particles, which is greatly affected by the environment.

[0024] The inner bottom of the smoke removal base box 1 is formed with a water filter chamber 21, and the upper side of the water filter chamber 21 is formed with a spray chamber 10 and a dehydration chamber 14, and the dehydration chamber 14 is formed with an air storage chamber on the side away from the spray chamber 10, and a spray dust removal component is fixedly installed inside the spray chamber 10, and a guide port 13 is opened through the inner bottom surface of the spray chamber 10, and a dehydration component is fixedly installed inside the dehydration chamber 14, and a guide port 20 is opened through the inner bottom surface of the dehydration chamber 14, and the air storage chamber and the dehydration chamber 14 are connected.

After the smoke gas is initially separated by the dust removal box 3, it enters the spray chamber 10 and uses the air inside the spray chamber 10 to adjust the ventilation volume. The spray dust removal component performs wet smoke removal on the smoke gas. At the same time, the substances in the smoke can combine with the water mist and sink to the bottom of the spray chamber 10 and enter the water filter chamber 21 through the guide port 13. The gas that has passed the wet dust removal enters the interior of the dehydration chamber 14, and the dehydration component inside the dehydration chamber 14 is used to dehydrate the gas with water mist, thereby reducing the content of water mist in the gas. The dehydrated gas enters the gas storage chamber through the demister 24, and the smoke is discharged using the silencer component inside the gas storage chamber.

[0025] Among them, the dust removal component includes a conical separation bucket 4 fixedly installed on the top surface of the dust removal box 3, an exhaust pipe 5 fixedly installed on the top of the conical separation bucket 4, a spiral blade 6 fixedly installed on the outer circumferential surface of the exhaust pipe 5 and a smoke inlet pipe 9 connected to the outside of the conical separation bucket 4.

The end of the air supply pipe 28 away from the exhaust pipe 5 passes through the smoke removal base box 1 and is connected with the spray chamber 10. The smoke can be transported to the interior of the conical separation bucket 4 through the smoke inlet pipe 9. The smoke entering the conical separation bucket 4 can spirally rotate along the inner wall of the conical separation bucket 4, and can preliminarily separate impurities in the smoke from the gas during the transportation process. The detached smoke dust particles can fall along the conical separation bucket 4 to the inside of the ash storage bin 7 for storage. At the same time, the smoke can be transported to the inside of the spray chamber 10 along the air supply pipe 28.

[0026] Among them, the spray dust removal assembly includes a plurality of guide plates 11 fixedly installed on the inner wall of the spray chamber 10 and a spray head fixedly installed on the outer surface of the water pipe 12 between the guide plates 11. Starting the water pump 30 can transport the water stored in the water storage chamber 23 to the inside of the spray chamber 10 along the water pipe 12, and spray the water in the form of water mist through the spray head on the outer surface of the water pipe 12. The water mist is used to adsorb and drop the particulate matter in the flue gas, thereby further reducing the presence of particulate matter in the flue gas.

[0027] The dehydration assembly includes a dehydration cylinder 15 fixedly mounted on the inner wall of the dehydration chamber 14, a dehydration turntable 17 rotatably mounted on the inner side of the dehydration cylinder 15, a plurality of dehydration mist sheets 18 fixedly mounted on the outer circumferential surface of the dehydration turntable 17, and a motor 16 fixedly mounted above the dehydration turntable 17. The output shaft of the motor 16 passes through the smoke removal base box 1 and is fixedly connected to the dehydration turntable 17. The plurality of dehydration mist sheets 18 are arranged circumferentially with equal spacing around the axis of the dehydration turntable 17. The surface of the dehydration mist sheet 18 is formed with a plurality of dehydration holes 19. The dehydration turntable 17 is rotatably mounted on the inner side of the dehydration cylinder 15. A ventilation gap is formed between the dehydration cylinders 15, and a ventilation hole is formed between the spray chamber 10 and the dehydration chamber 14. The motor 16 can drive the dehydration turntable 17 to rotate at a constant speed, and the smoke passing through the spray chamber 10 can flow along the gap between the dehydration turntable 17 and the dehydration cylinder 15. When the smoke passes through the dehydration turntable 17, the rotating dehydration mist sheet 18 contacts the smoke, and at the same time, the water mist carried in the smoke can adhere to the surface of the dehydration mist sheet 18, and can flow downward along the dehydration mist sheet 18 while gathering into water droplets, thereby removing the water mist in the smoke. Among them, the silencer assembly includes an exhaust pipe 25 fixedly installed on the top surface of the air storage chamber, an expansion cylinder 26 fixedly installed on the outer circumferential surface of the exhaust pipe 25, and a connecting port 27 opened between the exhaust pipe 25 and the expansion cylinder 26. The dehydrated smoke can be discharged from the smoke removal box 1 along the exhaust pipe 25. In the process of transporting the smoke through the exhaust pipe 25, the expansion cylinder 26 can be used to expand and reduce the noise of the smoke, thereby reducing the sound of the smoke discharged through the exhaust pipe 25.

[0028] The working principle of the present invention is as follows: when in use, the flue gas generated in industrial production can be transported to the inside of the dust removal box 3, and the dust removal components inside the dust removal box 3 are used to preliminarily separate the particulate matter in the flue gas from the flue gas, and the impurity particles separated from the flue gas directly fall into the ash storage bin 7 for storage, and the particulate matter stored in the ash storage bin 7 can be discharged by opening the ash removal plate 8;

[0029] The flue gas entering the conical separation bucket 4 can spirally rotate along the inner wall of the conical separation bucket 4, and can initially separate the impurities in the flue gas from the gas during the transportation process. The separated smoke particles can fall along the conical separation bucket 4 to the inside of the ash storage bin 7 for storage, and the flue gas can be transported to the inside of the spray chamber 10 along the gas delivery pipe 28;

[0030] The water pump 30 can transport the water stored in the water storage chamber 23 to the inside of the spray chamber 10 along the water delivery pipe 12, and spray the water in the form of water mist through the spray head on the outer surface of the water delivery pipe 12 in the spray chamber 10, so as to absorb the particulate matter in the smoke and drop it, thereby further reducing the presence of particulate matter in the smoke.

[0031] The motor 16 drives the dehydration turntable 17 to rotate at a constant speed, and the flue gas passing through the spray chamber 10 can flow along the gap between the dehydration turntable 17 and the dehydration cylinder 15. When the flue gas passes through the dehydration turntable 17, the rotating dehydration mist sheet 18 contacts the flue gas. At this time, the water mist carried in the flue gas can adhere to the surface of the dehydration mist sheet 18, and flow downward along the dehydration mist sheet 18 while gathering into water droplets, thereby achieving the removal of the water mist in the flue gas. Finally, the flue gas can be expanded and noise-reduced by the expansion cylinder 26 during the process of being transported through the exhaust duct 25, thereby reducing the sound of the smoke discharged through the exhaust duct 25.
