AI Technical Summary
Existing boiler flue gas dust removal devices have poor purification effects and simple purification channel structures.
A wet flue gas dust removal device is designed, comprising a water tank chamber and a water mist chamber inside the housing. The flue gas first enters at the bottom of the water tank chamber, forming bubbles that come into contact with water for initial purification. Then, water mist is sprayed out through atomizing nozzles in the water mist chamber for secondary purification. A U-shaped channel is used to increase the flue gas flow distance to enhance the purification effect.
By increasing the contact time and extending the flow distance, the purification effect of flue gas is significantly improved, and the ability to remove dust and pollutants is enhanced.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas dust removal technology, specifically a wet flue gas dust removal device. Background Technology
[0002] Boilers inevitably generate dust and flue gas during operation. Boiler dust removal is the process of separating dust from flue gas, thereby reducing dust pollution and facilitating further desulfurization, denitrification and other treatments of the flue gas. With social development, environmental protection is receiving increasing attention, and boiler dust removal has been applied to various fields such as thermal power generation.
[0003] For example, the utility model patent with announcement number CN214552207U discloses a boiler flue gas dust removal device, which is composed of a dust removal chamber and a water film dust removal chamber. The flue gas enters from the inlet pipe and is sprayed and washed through a primary spray pipe. The sprayed gas enters the water film dust removal chamber and is sprayed and washed a second time in the water film dust removal chamber.
[0004] However, existing dust collectors generally purify flue gas by spraying water mist, and the purification channel structure is relatively simple, resulting in poor purification effect. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a wet flue gas dust removal device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wet flue gas dust removal device, comprising a housing, a partition plate fixedly installed inside the housing, a channel for gas passage between the top of the partition plate and the upper wall of the housing, forming a water tank cavity and a water mist cavity inside the housing through the partition plate, an air inlet pipe provided in the water tank cavity, one end of the air inlet pipe extending to the outside of the housing, and the other end extending to the bottom of the water tank cavity, an air outlet being provided on the side wall of the housing near the water mist cavity, multiple atomizing nozzles being installed in the water mist cavity, and a water supply pipe being installed on the upper wall of the housing above the water tank cavity.
[0007] Preferably, a partition two is fixedly installed inside the water mist chamber, which enables the formation of a U-shaped gas channel inside the water mist chamber, and multiple atomizing nozzles are installed on both sides of the partition two.
[0008] Preferably, the bottom of both the water tank cavity and the water mist cavity is a bucket-shaped structure, the bottom of the water tank cavity is connected to a sludge discharge pipe, and the bottom of the water mist cavity is connected to a drain pipe.
[0009] Preferably, a plurality of air distribution plates are fixedly arranged in the vertical direction inside the water tank cavity, and a plurality of air distribution holes are opened on the air distribution plates.
[0010] Preferably, one end of the air inlet pipe corresponds to the position of the air outlet.
[0011] Beneficial effects
[0012] This utility model provides a wet flue gas dust removal device with the following beneficial effects: This device allows flue gas to undergo initial filtration in the form of bubbles through a water tank cavity. By placing the water tank cavity on one side of the housing, the height of the water tank cavity can be increased, thereby increasing the contact time between the bubbles and water. Multiple air distribution holes on the air distribution plate inside the water tank cavity can disperse the floating bubbles into multiple small bubbles, allowing the bubbles to fully contact the water. The water mist cavity through the U-shaped channel can increase the flow distance of the flue gas, allowing the flue gas to fully contact the water mist, further improving the purification effect.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] Please see Figure 1This utility model provides a technical solution: a wet flue gas dust removal device, including a housing 1, a partition 2 fixedly installed inside the housing 1, a channel for gas passage between the top of the partition 2 and the upper wall of the housing 1, forming a water tank cavity 3 and a water mist cavity 4 inside the housing 1 through the partition 2, the water tank cavity 3 can store water for purifying flue gas, an air inlet pipe 5 is provided in the water tank cavity 3, one end of the air inlet pipe 5 extends to the outside of the housing 1, and the other end of the air inlet pipe 5 extends to the bottom of the water tank cavity 3, an air outlet 6 is opened on the side wall of the housing 1 near the water mist cavity 4, and multiple atomizing nozzles 7 are installed in the water mist cavity 4. A water supply pipe 9 for filling the water tank 3 is installed on the upper wall above the water tank cavity 3. The flue gas can enter the box 1 through the air inlet pipe 5. The flue gas will first be discharged to the bottom of the water tank cavity 3. After the flue gas is discharged, it will form smoke bubbles and come into contact with the water in the water tank cavity 3 to achieve the initial purification of the flue gas. Since the water tank cavity 3 is located on one side of the box 1, the height of the water tank cavity 3 is increased, which increases the contact time between the bubbles and the water. After the smoke bubbles move to the water surface, they will enter the water mist cavity 4. Water mist can be sprayed out through the atomizing nozzle 7 to achieve the secondary purification of the flue gas. The purified flue gas can be discharged through the air outlet 6.
[0019] As an embodiment of this utility model, a partition 2 8 is fixedly installed inside the water mist chamber 4. The partition 2 8 enables the formation of a U-shaped gas channel inside the water mist chamber 4. Multiple atomizing nozzles 7 are installed on both sides of the partition 2 8. The partition 2 8 increases the length of the flue gas channel and the flow distance of the flue gas. By setting the atomizing nozzles 7 on the partition 2 8, the flue gas can fully contact the water mist, further improving the purification effect.
[0020] As an embodiment of this utility model, the bottom of both the water tank cavity 3 and the water mist cavity 4 is a bucket-shaped structure. The bottom of the water tank cavity 3 is connected to a mud discharge pipe 10, through which the sludge at the bottom of the water tank cavity 3 can be discharged. The bottom of the water mist cavity 4 is connected to a drain pipe 11, through which the water in the atomizing cavity 4 can be discharged.
