Description

Technical Field

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

[0002] With the acceleration of industrialization, the problem of waste gas emissions has become increasingly prominent. The moisture carried in the waste gas not only pollutes the environment, but also may corrode the waste gas treatment equipment, affecting the normal operation of the equipment. Therefore, the research and development and application of waste gas dehumidification technology is particularly important, which is of great significance for improving waste gas treatment efficiency, protecting the environment and maintaining stable operation of equipment.

[0003] Deficiencies of existing technology:

[0004] At present, there are some devices for waste gas dehumidification on the market. Most of them adopt the principle of centrifugal dehydration. Through the high-speed rotating centrifugal cylinder, centrifugal force is used to separate the water in the waste gas. These devices are usually composed of components such as an air inlet, a centrifugal cylinder, a drain and an air outlet. In the actual work process, the waste gas enters the centrifugal cylinder from the air inlet. Under the action of centrifugal force, the water in the waste gas is thrown to the cylinder wall and flows down, while the dry waste gas is discharged from the air outlet. However, the existing dehumidification and dehumidification equipment still has some shortcomings. First, due to the high-speed rotation of the air flow in the centrifugal cylinder, some water vapor may be carried out of the centrifugal cylinder by the air flow due to inertia, resulting in poor dehumidification effect. Secondly, because the exhaust gas moves and rises too fast in the centrifugal cylinder, it does not contact the cylinder wall sufficiently, which makes the dehumidification efficiency low. In addition, in order to ensure the dehumidification efficiency, some equipment will adopt the method of raising the centrifugal cylinder to increase the contact area and contact time between the exhaust gas and the cylinder wall, but this will cause the overall volume of the equipment to become larger, especially the longitudinal space is occupied too much, and the space utilization rate is low.

[0034] See also Figure 1-5As shown, the utility model provides a technical solution for a waste gas dehydration device: a waste gas dehydration device, including an installation box 1, the interior of the installation box 1 is divided into a separation chamber 2 and a drive chamber 3, a dehumidification component 4 is movably installed in the separation chamber 2, an air intake drive mechanism 5 is movably installed in the drive chamber 3, the upper end of the installation box 1 is connected to an exhaust pipe 6, and the box wall at the lower end of the installation box 1 is connected to an air intake pipe 7. The dehumidification component 4 includes a mounting shaft 401, a lower condensation hood 404 and a connecting column 406. The mounting shaft 401 is rotatably connected to the lower end of the separation chamber 2 and is located on the partition inside the mounting box 1. A plurality of arc-shaped blades 402 are obliquely installed on the shaft wall of the mounting shaft 401 to drive the rising exhaust gas to rotate outward. A guide plate 403 is installed on the upper end of the mounting shaft 401. The lower condensation hood 404 is installed on the inner wall of the separation chamber 2. The lower condensation hood 404 is conical, and an exhaust hole 405 is opened through the upper end of the lower condensation hood 404. The guide plate 403 cooperates with the arc-shaped blades 402 to prevent the exhaust gas from rising directly and being discharged from the exhaust hole 405. The connecting column 406 is fixedly installed on the inner wall of the upper end of the separation chamber 2, and the lower end of the connecting column 406 is connected to an upper condensation hood 407 matching the lower condensation hood 404. When the discharged waste gas needs to be dehydrated, the waste gas is first transported into the driving chamber 3 through the air inlet pipe 7 to drive the driving mechanism 5 to operate, and the driving mechanism 5 drives the installation shaft 401 and the arc-shaped blades 402 to start rotating. The waste gas to be treated passes through the diaphragm in the installation box 1 and enters the separation chamber 2, and starts to rotate around the installation shaft 401 driven by the arc blades 402. The rotating waste gas rises along the edge of the guide plate 403 under the guidance of the centrifugal force and the guide plate 403 and enters the lower condensation hood 404. After entering the lower condensation hood 404, the waste gas rises along the inner wall of the lower condensation hood 404 and produces condensed water. The condensed water slides down along the inner wall of the lower condensation hood 404, and the waste gas continues to rise through the exhaust hole 405 and enters the upper condensation hood 407. Due to the continuous input of waste gas, the waste gas pressure in the upper condensation hood 407 is higher than the atmospheric pressure. Therefore, the internal waste gas flows downward along the inner wall of the upper condensation hood 407 for secondary condensation. Finally, the waste gas that has completed the secondary dehydration leaves the upper condensation hood 407 and is discharged through the exhaust pipe 6 along the upper box body of the installation box 1. Through the dehumidification component 4, effective dehumidification of the waste gas to be treated is achieved. Compared with the traditional centrifugal dehydration, the flow rate of the waste gas is slower, and the two-time dehydration method is adopted to avoid the water vapor being carried out of the centrifugal cylinder due to inertia. The overall condensation time of the waste gas is longer, the condensation process is more complete, and the dehydration effect is significantly improved. At the same time, the longitudinal space of the dehydration device is reduced, and the space utilization rate is improved.

[0035] The air intake drive mechanism 5 includes a bellows 501, an air duct 503, a driving shaft 504 and a driving gear 506. The bellows 501 is fixedly installed on one side of the driving chamber 3. The air intake pipe 7 passes through the lower box wall of the installation box 1 and is connected to one side of the bellows 501. An air guide pipe 502 is installed on the side of the bellows 501 away from the air intake pipe 7. The air duct 503 is opened on the diaphragm in the installation box 1. The lower end of the air duct 503 is connected to the air guide pipe 502. The upper and lower ends of the driving shaft 504 are rotatably connected to the diaphragm and the lower box bottom in the installation box 1 respectively. A plurality of driving blades 505 are welded on the shaft wall of the driving shaft 504. The driving gear 506 is installed at the upper end of the driving shaft 504 in a cavity opened on the diaphragm of the installation box 1. The lower end of the installation shaft 401 is located in the cavity opened on the diaphragm of the installation box 1 and is installed with a driven gear 507. The driving gear 506 meshes with the driven gear 507. The discharged waste gas enters the bellows 501 from the air intake pipe 7, and the flow of the waste gas forms a thrust on the driving blades 505 to drive the driving shaft 504 to rotate. The driving shaft 504 drives the installation shaft 401 and the arc-shaped blades 402 to rotate through the driving gear 506 and the driven gear 507 to achieve the driving effect. The waste gas in the bellows 501 rotates with the driving blades 505 and is discharged to the air duct 503 through the air duct 502 when passing through the air duct 502, and finally discharged from the top of the air duct 503 into the separation chamber 2. Through the air intake drive mechanism 5, the effect of using the wind energy of the waste gas to be treated to drive the installation shaft 401 and the arc-shaped blades 402 to rotate is achieved, without energy consumption, and the overall structure is simple, no additional driving equipment is involved, the working life is long, and the later maintenance is convenient.

[0036] An exhaust groove 601 is provided on the box body at the upper end of the installation box 1 below the exhaust pipe 6. The exhaust gas that has been dehumidified and removed rises and is discharged to the exhaust pipe 6 through the exhaust groove 601. The connecting column 406 is installed between the exhaust grooves 601.

[0037] The lower edge of the separation chamber 2 is chamfered, which is more conducive to guiding the airflow to move upward.

[0038] A plurality of drainage holes 4041 are provided on the lower side of the hood body of the lower condensation hood 404. After a long period of operation, the condensed water generated on the lower end surface of the upper condensation hood 407 will drip onto the lower condensation hood 404. The drainage holes 4041 can facilitate the downward discharge of this part of the condensed water. The condensed water will eventually gather at the lower end of the separation chamber 2 and be discharged along the drainage pipe on one side of the partition in the installation box 1.

[0039] The air outlet of the air duct 503 is located below the arc-shaped blades 402 , and the exhaust gas can be directly captured by the arc-shaped blades 402 after rising and leaving the air duct 503 .

[0040] The air outlet of the air duct 503 is heightened to prevent condensed water from flowing back into the driving chamber 3 through the air duct 503 .
