Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a spray dust removal device. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes within the enterprise's factory area. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, smoke and industrial dust. In order to prevent smoke and dust from being discharged into the air and affecting environmental safety, the dust and smoke need to be sprayed before the industrial waste gas is discharged (spraying dust removal is effective for large-particle dust and smoke).

[0003] Chinese patent CN219002429U discloses an industrial waste gas dust removal device, including a tower body, on which a waste gas inlet pipe and a waste gas outlet pipe are respectively arranged. The tower body is divided into a purification chamber and a washing chamber distributed up and down by a partition plate, the waste gas inlet pipe is connected to the washing chamber, the waste gas outlet pipe is connected to the purification chamber, and a plurality of vents are arranged on the partition plate.

[0004] In the above patent, the exhaust gas inlet pipe directly passes the exhaust gas into the washing water, and there is a lack of a mechanism for dividing the exhaust gas. The contact surface area between the exhaust gas and the washing water is small, and the washing and dust removal effect of the washing water on the exhaust gas is poor. At the same time, due to the presence of the motor, the position between the motor and the dividing plate cannot be sprayed. When the exhaust gas intake volume is large, it is easy for some exhaust gas that has not been completely dust-removed to pass directly through the spray nozzle, reducing the dust removal effect. Therefore, a technical measure is proposed to solve the problem of lack of a mechanism for dividing the exhaust gas, small contact surface area between the exhaust gas and the washing water, and poor washing and dust removal effect of the washing water on the exhaust gas. Due to the presence of the motor, the position between the motor and the dividing plate cannot be sprayed. When the exhaust gas intake volume is large, it is easy for some exhaust gas that has not been completely dust-removed to pass directly through the spray nozzle, reducing the dust removal effect.

A drain pipe 7 is provided, on which a valve 10 is installed. A connecting pipe 9 is connected between the dust removal box 8 and the tank body 4. When the waste gas is dust-removed, the waste gas generated by the industrial waste gas is connected to the air segmentation component 2. Under the action of the air segmentation component 2, the waste gas enters the dust removal box 8 for dust removal. After the waste gas is washed, it enters the connecting pipe 9 through the dust removal box 8, and then enters the tank body 4. The spray component 3 is started to perform secondary dust removal on the waste gas. The waste gas after dust removal passes upward through the air holes 15 of the partition 12 and enters the desiccant 13. The desiccant 13 dries the moisture in the waste gas. Then the waste gas passes through the air holes 15 of the partition 12 and enters the exhaust pipe 6 to be aired.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the air segmentation component 2 includes an air inlet pipe 201, which is connected to the industrial waste gas, and the air inlet pipe 201 is connected to the dust removal box 8, and the air inlet pipe 201 is connected to the ring plate 202, and the ring plate 202 is inside the dust removal box 8. Two groups of branch pipes 203 are installed at both ends of the side of the air inlet pipe 201, and the other end of the branch pipe 203 is connected to the ring plate 202.

The other end of the water pump 301 is connected to a vertical pipe 306, and the vertical pipe 306 is Z-shaped. The other end of the vertical pipe 306 is connected to an arc plate 303. The spray component 3 also includes a water supply pipe 305, and the water supply pipe 305 has two groups. Two groups of water supply pipes 305 are fixedly installed on the side of the vertical pipe 306. The water supply pipe 305 passes through the arc plate 303. The arc plate 303 is adapted to the curvature of the tank body 4. The other end of the water supply pipe 305 is connected to the spray plate 304. The spray plate 304 is adapted to the through hole 14. A plurality of groups of evenly distributed nozzles 307 are installed on the surface of the spray plate 304. The exhaust gas first enters the air intake pipe 201, and then the exhaust gas enters the ring plate 202 through the air intake pipe 201 and the branch pipe 203, and then the exhaust gas enters the air pipe 204. The exhaust gas enters the washing water inside the dust removal box 8 through the air pipe 204, and contacts with the washing water for washing and dust removal. The water pump 301 is started to pump water to the vertical pipe 306, and then the water flows into the water supply pipe 305. Under the action of the water pump 301, the water then enters the spray plate 304, and finally the water flows into the nozzle 307 to spray and dust remove the exhaust gas.

[0027] Working principle: When removing dust from exhaust gas, the exhaust gas generated by industrial exhaust gas is connected to the air segmentation component 2. Under the action of the air segmentation component 2, the exhaust gas enters the dust removal box 8 for dust removal (there is washing water inside the dust removal box 8, and the washing water can be injected through the water injection pipe 11. The dust removal box 8 is provided with an inspection port on the side). Specifically, the exhaust gas first enters the air intake pipe 201, and then the exhaust gas enters the ring plate 202 through the air intake pipe 201 and the branch pipe 203, and then the exhaust gas enters the air pipe 204. The exhaust gas enters the washing water inside the dust removal box 8 through the air pipe 204, and contacts with the washing water for washing and dust removal. Through the setting of the air segmentation component 2, the exhaust gas is divided into small bubbles, thereby increasing the contact surface area between the exhaust gas and the washing water and improving the dust removal effect.

[0028] After the exhaust gas is washed, it enters the connecting pipe 9 through the dust removal box 8, and then enters the tank body 4. The spray assembly 3 is started to perform secondary dust removal on the exhaust gas, and the water pump 301 is started (wherein the water inlet pipe 302 is connected to the external water source). The water pump 301 is started to pump water to the vertical pipe 306, and then the water flows into the water delivery pipe 305. Under the action of the water pump 301, the water flows into the spray plate 304, and finally the water flows into the nozzle 307 to spray and remove dust from the exhaust gas. Through the setting of the spray assembly 3, all-round spraying is realized in the vertical direction of the tank body 4, so as to prevent the exhaust gas that has not been completely sprayed and dusted from directly passing through the tank body 4 when the exhaust gas intake volume is large;

[0029] The exhaust gas after dust removal passes upward through the pores 15 of the partition 12 and enters the desiccant 13 (the exhaust gas has high humidity, which will make the humidity of the space around the dust removal equipment high, which is easy to cause rust of the equipment). The desiccant 13 dries the moisture in the exhaust gas. Then the exhaust gas passes through the pores 15 of the partition 12 and enters the exhaust pipe 6 to be aired. Through the setting of the tank door 5, the desiccant 13 can be easily replaced. When there is a lot of water inside the tank body 4 and the dust removal box 8, the valve 10 can be opened to allow the water to be discharged through the drain pipe 7.
