An energy-saving waste heat recovery RTO waste gas treatment device

Abstract

The present application relates to the technical field of heat recovery equipment, and discloses an energy-saving waste heat recovery RTO waste gas treatment device, in order to solve the problem that the cooling water is not in full contact with the heat exchange tube, resulting in that part of the purified gas still has a high heat. The present invention arranges the upper baffle, the slide plate and the cylinder. As the liquid level of the cooling water gradually rises, the slide plate moves upward, so that there is a space between the upper side of the upper baffle and the inner wall of the cylinder. Since the cylinder is inclined, the gradually rising liquid level of the cooling water squeezes out the air in the cylinder. Through this action, the contact area between the cooling water and the heat exchange tube is increased, so that more heat in the purified gas is absorbed by the cooling water, thereby reducing the probability of heat waste.

Description

Technical Field

[0001] The present application relates to the technical field of heat recovery equipment, and in particular to an energy-saving waste heat recovery RTO waste gas treatment device. Background Art

[0002] Industrial waste gas refers to the general term for various exhaust gases (containing pollutant gases) generated during fuel combustion and production processes within the factory. Nowadays, waste heat recovery RTO waste gas treatment devices are often used to purify industrial waste gas.

[0003] Some existing waste heat recovery RTO waste gas treatment devices are mainly composed of a furnace body and a heat exchanger. When in use, the industrial waste gas first enters the heat storage body through the rotary distribution valve in the furnace body, and then is preliminarily heated. After that, the waste gas passing through the heat storage body is acted upon by the burner, and then thermal oxidation occurs, so that the organic matter in the waste gas is basically converted into carbon dioxide and water. After that, the purified gas passes through another heat storage body and a heat exchanger. In this process, the purified gas passes through the heat exchange tubes in the heat exchanger and is then discharged to the external environment, while the cooling water flows in a zigzag manner in the channel composed of the upper and lower baffles in the cooling chamber and contacts the heat exchange tubes. The heat exchanger is used to recover the waste heat of the purified gas, thereby achieving energy saving and environmental protection functions.

[0004] However, in the process of the purified gas passing through the heat exchanger, since the cooling water flows in the cooling chamber along the channel composed of the upper and lower baffles, air is easily present between the liquid surface of the cooling water and the upper inner wall of the heat exchanger shell, resulting in a reduction in the contact area between the heat exchange tube at the top and the cooling water, so that part of the purified gas still has a high heat content, thereby causing heat waste. Summary of the invention

[0005] The present application proposes an energy-saving waste heat recovery RTO waste gas treatment device, which has the advantage of reducing the heat waste of the purified gas, and is used to solve the problem that the cooling water does not fully contact with the heat exchange tube, resulting in part of the purified gas still having a high heat.

[0008] Furthermore, the purification mechanism includes a rotary distribution valve, a heat storage body, a burner, an exhaust gas pipe and a clean air pipe. A rotary distribution valve is provided at the lower part of the inner cavity of the furnace body, a heat storage body is provided above the rotary distribution valve, a burner is fixedly installed on one side of the furnace body and above the heat storage body, an exhaust gas pipe is connected to one side of the rotary distribution valve, and a clean air pipe is connected to the other side of the rotary distribution valve, and the clean air pipe is connected to the air cavity on one side.

[0009] Furthermore, partitions are fixedly installed on both sides of the inner cavity of the cylinder, the cavity between the circular inner wall of the cylinder and the corresponding partition is an air cavity, the cavity between the two partitions is a cooling cavity, and both ends of the heat exchange tube are fixedly installed on the corresponding partitions.

[0010] Furthermore, the force-applying mechanism includes a mounting seat, a turntable, a pull rope and a motor. The mounting seat is fixedly installed on the upper side of the cylinder, and a turntable is rotatably installed inside the mounting seat and at a position corresponding to the skateboard. A pull rope is wrapped around the outside of the turntable, one end of the pull rope is fixedly connected to the turntable, and the other end of the pull rope is fixedly connected to the upper side of the skateboard. An air venting hole is opened inside the mounting seat, and a motor is fixedly installed on one side of the mounting seat. The center position of the turntable is fixedly connected to the rotating shaft of the motor.

[0011] Furthermore, a side of the cylinder body close to the water outlet pipe is inclined upward.

[0012] Furthermore, a telescopic rod is fixedly installed on the side of the cylinder facing away from the clean air pipe, and the output rod of the telescopic rod passes through the wall of the cylinder and the partition in the corresponding direction, and the output rod of the telescopic rod forms a sealed sliding connection with the wall and partition of the cylinder. A No. 1 baffle plate is provided in the space between the baffle close to the direction of the air outlet pipe and the nearest upper deflector plate, and the No. 1 baffle plate forms a sliding contact with the heat exchange tube. The output rod of the telescopic rod is fixedly connected to the No. 1 baffle plate, and there is a gap between the lower side of the No. 1 baffle plate and the lower inner wall of the cylinder, and the upper side of the No. 1 baffle plate forms a sliding contact with the inner wall of the cylinder.

[0013] Furthermore, a No. 2 baffle plate is provided in the space between the lower baffle plate and the upper baffle plate, and the No. 2 baffle plate forms a sliding contact with the heat exchange tube. There is a spacing between the upper side and the lower side of the No. 2 baffle plate and the inner wall of the cylinder in the corresponding direction. The output rod of the telescopic rod passes through the upper baffle plate and the lower baffle plate, and forms a fixed connection with the No. 2 baffle plate. The output rod of the telescopic rod forms a sliding contact with both the upper baffle plate and the lower baffle plate.

[0014] Furthermore, the lower portion of the second blocking plate is axially staggered with the upper portion of the lower deflector.

[0015] This application has the following beneficial effects:

[0016] The present application provides an energy-saving waste heat recovery RTO waste gas treatment device. Through the arrangement of an upper baffle, a slide plate and a cylinder, as the liquid level of cooling water gradually rises, the slide plate moves upward, so that space appears between the upper side of the upper baffle and the inner wall of the cylinder. Since the cylinder is arranged at an angle, the gradually rising liquid level of cooling water squeezes out the air in the cylinder. Through this action, the contact area between the cooling water and the heat exchange tube is increased, so that more heat in the purified gas is absorbed by the cooling water, thereby reducing the probability of heat waste.

[0017] By setting the upper baffle plate, the slide plate and the No. 1 baffle plate, when there are bubbles in the cooling water input into the cylinder, the No. 1 baffle plate is intermittently moved to the side of the outlet pipe close to the water inlet pipe, and the slide plate is moved upward, so that the bubbles are pushed by the water flow to pass through the upper baffle plate and are finally blocked by the No. 1 baffle plate. After that, the slide plate and the No. 1 baffle plate are reset in turn, so that the No. 1 baffle plate pulls the bubbles to the outlet pipe. Through this action, the contact area between the cooling water and the heat exchange tube is further increased. In addition, through the blocking of the No. 1 baffle plate, the water flow that drives the bubbles to move will mix downward with the water flow at other positions, thereby avoiding a short contact time between the water flow and the heat exchange tube, which causes the temperature of the discharged water to be affected.

[0018] Through the arrangement of the telescopic rod and the No. 2 baffle plate, when the bubbles are concentrated on the upper inner wall of the cylinder and the position of the upper baffle plate, the telescopic rod drives the No. 2 baffle plate to move intermittently, thereby extending the lower baffle plate to a certain extent, so that part of the water flowing through the upper side of the lower baffle plate will flow through the upper side of the No. 2 baffle plate, and then the water flow will contact and stir the above-mentioned bubbles, so that the contact area between the corresponding heat exchange tube and the cooling water is increased intermittently.

[0019] By setting the telescopic rod and the second baffle plate, in the process of the above-mentioned part of the water flow flowing through the upper side of the second baffle plate, the flow velocity of the water flow is accelerated, and the water flow with accelerated flow velocity contacts the air bubbles, thereby making it easier for the air bubbles to be driven downward, and then gradually pass through the tortuous channel and flow out of the water outlet pipe. Through this action, the contact area between the corresponding heat exchange tube and the cold water is increased. At the same time, when the above-mentioned slide plate moves upward, since the water flow flowing through the upper side of the second baffle plate is closer to the air bubbles, the water flow can more easily drive the above-mentioned air bubbles to move toward the water outlet pipe, thereby increasing the contact area between the corresponding heat exchange tube and the cold water.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Example 1: Please refer to Figure 1 An energy-saving waste heat recovery RTO waste gas treatment device includes a furnace body 1, a rotary distribution valve 2 is arranged at the lower part of the inner cavity of the furnace body 1, a heat storage body 3 is arranged above the rotary distribution valve 2, a burner 4 is fixedly installed on one side of the furnace body 1 and above the heat storage body 3, an exhaust gas pipe 5 is connected to one side of the rotary distribution valve 2, and a clean gas pipe 6 is connected to the other side of the rotary distribution valve 2.

[0031] When in use, the industrial waste gas first passes through the waste gas pipe 5 and the rotary distribution valve 2, and then passes through the heat storage body 3 on one side, so that the waste gas is preliminarily heated. Afterwards, the waste gas passing through the heat storage body 3 is affected by the flame of the burner 4, and then thermal oxidation occurs, so that the organic matter in the waste gas is basically converted into carbon dioxide and water. Afterwards, the purified gas passes through the heat storage body 3 and the rotary distribution valve 2 on the other side, and then is discharged from the clean air pipe 6. Through the above actions, the waste gas is purified.

[0032] See also Figure 2-Figure 6A cylinder 7 is provided on one side of the furnace body 1, and partitions 8 are fixedly installed on both sides of the inner cavity of the cylinder 7. The cavity between the circular inner wall of the cylinder 7 and the corresponding partition 8 is an air cavity, and the cavity between the two partitions 8 is a cooling cavity. The clean air pipe 6 is connected with the air cavity on one side, and an air outlet pipe 9 is fixedly installed on the upper side of the cylinder 7 and at a position corresponding to the air cavity on the other side. The air outlet pipe 9 connects the external environment with the air cavity on the other side. Heat exchange tubes 10 are equidistantly arranged inside the cooling cavity, and both ends of the heat exchange tubes 10 are fixedly installed on the corresponding partitions 8. The air cavities on both sides are connected through the heat exchange tube 10. A water inlet pipe 11 is fixedly installed on the lower side of the cylinder 7 and close to the clean air pipe 6. The water inlet pipe 11 connects the water inlet mechanism (such as a water pump) and the cooling chamber. A water outlet pipe 12 is fixedly installed on the upper side of the cylinder 7 and close to the air outlet pipe 9. The water outlet pipe 12 connects the utilization mechanism (such as a heating equipment) and the cooling chamber. Lower baffles 13 and upper baffles 14 are alternately arranged axially in the cooling chamber. The lower baffles 13 and the upper baffles 14 are fixedly connected to the heat exchange tube 10.

[0033] The purified gas passes through the clean air pipe 6, the air cavity on one side, the heat exchange tube 10 and the air cavity on the other side, and is then discharged to the external environment from the outlet pipe 9. In this process, cooling water enters the cooling cavity through the water inlet pipe 11, and flows in the tortuous channel formed by the lower baffle 13 and the upper baffle 14, and finally flows from the water outlet pipe 12 to the utilization mechanism. The cooling water will contact the heat exchange tube 10 during the flow in the cooling cavity, so that the heat of the gas is transferred to the cooling water. Through this action, the waste heat of the purified gas is recovered, thereby achieving energy saving and environmental protection functions.

[0034] See also Figure 2-Figure 6 There is a gap between the upper side of the lower baffle 13 and the upper inner wall of the cylinder 7, and there is a gap between the upper and lower sides of the upper baffle 14 and the inner wall of the cylinder 7 in the corresponding direction. A slide groove 15 is provided in the upper wall of the cylinder 7 and corresponds to the position of the upper baffle 14. A slide plate 16 is sealed and slidably installed in the slide groove 15. The lower side of the slide plate 16 is in contact with the upper side of the upper baffle 14. A spring 17 is provided in the slide groove 15 and above the slide plate 16. The two ends of the spring 17 are fixedly connected to the upper side of the slide plate 16 and the inner wall of the slide groove 15 respectively. A mounting seat 18 is fixedly installed on the upper side of the cylinder 7. A turntable 19 is rotatably installed inside the mounting seat 18 and at the position corresponding to the slide 16. A pull rope 20 is wrapped around the outside of the turntable 19. One end of the pull rope 20 is fixedly connected to the turntable 19, and the other end of the pull rope 20 extends into the slide 15 and is fixedly connected to the upper side of the slide 16. An air vent is opened inside the mounting seat 18, and the slide 15 is connected to the air vent through the position where the pull rope 20 passes, and then to the external environment. A motor 21 is fixedly installed on one side of the mounting seat 18, and the center position of the turntable 19 is fixedly connected to the rotating shaft of the motor 21. The side of the cylinder 7 close to the water outlet pipe 12 is tilted upward.

[0035] When the cooling water flows in a zigzag manner in the cooling chamber, the gas in the cooling chamber will be concentrated on the upper inner wall of the cylinder 7 and the position of the upper baffle 14. Then, as the cooling water level gradually rises, the motor 21 rotates, so that the turntable 19 drives the slide plate 16 to move upward through the pull rope 20, and compresses the corresponding spring 17, so that a space appears between the upper side of the upper baffle 14 and the inner wall of the cylinder 7. Then, as the liquid level continues to rise, part of the cooling water that enters later will flow into the above-mentioned space. Since the cylinder 7 is inclined, the gradually rising liquid level of the cooling water squeezes out the air in the cylinder 7. Through this action, the contact area between the cooling water and the heat exchange tube 10 is increased, so that more heat in the purified gas is absorbed by the cooling water, thereby reducing the probability of heat waste. Then, the motor 21 reverses, so that the spring 17 releases the elastic force, and drives the slide plate 16 to fit and contact the upper baffle 14 again.

[0036] Example 2: Please refer to Figure 2-Figure 6 This embodiment is a further improvement of the first embodiment, and the improvement lies in that a telescopic rod 22 (such as a combination of an electric telescopic cylinder and an output rod in the prior art) is fixedly installed on the side of the cylinder 7 facing away from the clean air pipe 6, the output rod of the telescopic rod 22 passes through the wall of the cylinder 7 and the partition 8 in the corresponding direction, the output rod of the telescopic rod 22 forms a sealed sliding connection with the wall of the cylinder 7 and the partition 8, a No. 1 blocking plate 23 is arranged in the space between the partition 8 close to the direction of the air outlet pipe 9 and the nearest upper baffle 14, the No. 1 blocking plate 23 forms a sliding contact with the heat exchange tube 10, the output rod end of the telescopic rod 22 is fixedly connected to the No. 1 blocking plate 23, there is a gap between the lower side of the No. 1 blocking plate 23 and the lower inner wall of the cylinder 7, and the upper side of the No. 1 blocking plate 23 forms a sliding contact with the inner wall of the cylinder 7.

[0037] When there are bubbles in the cooling water input into the cooling chamber, most of the bubbles will be affected by their own buoyancy and then concentrated on the upper inner wall of the cylinder 7 and the position of the upper baffle 14. After a period of time, the telescopic rod 22 intermittently extends and drives the first blocking plate 23 to move to the side of the water outlet pipe 12 close to the water inlet pipe 11 (such as Figure 6 As shown), the slide plate 16 is then moved upward, so that the bubbles are pushed by the subsequent water flow through the upper baffle plate 14 and are finally blocked by the No. 1 blocking plate 23. Afterwards, the slide plate 16 and the No. 1 blocking plate 23 are reset in sequence, so that the No. 1 blocking plate 23 pulls the bubbles toward the outlet pipe 12 and finally discharges them with the water flow. Through this action, the contact area between the cooling water and the heat exchange tube 10 is increased. In addition, through the blocking of the No. 1 blocking plate 23, the water flow that drives the bubbles to move will move downward along the No. 1 blocking plate 23 and mix with the water flow at other positions, thereby reducing the contact time between the water flow and the heat exchange tube 10, resulting in a shorter contact time between the water flow and the heat exchange tube 10, resulting in the influence on the temperature of the discharged water.

[0038] Example 3: Please refer to Figure 2-Figure 6This embodiment is a further improvement of the second embodiment, and the improvement lies in that: a No. 2 baffle plate 24 is provided in the space between the lower baffle plate 13 and the upper baffle plate 14 (there is no No. 2 baffle plate 24 in the space between the upper baffle plate 14 and the lower baffle plate 13), the No. 2 baffle plate 24 forms a sliding contact with the heat exchange tube 10, and there is a gap between the upper side and the lower side of the No. 2 baffle plate 24 and the inner wall of the cylinder 7 in the corresponding direction, the output rod of the telescopic rod 22 passes through the upper baffle plate 14 and the lower baffle plate 13, and then forms a fixed connection with the No. 2 baffle plate 24, the output rod of the telescopic rod 22 forms a sliding contact with the upper baffle plate 14 and the lower baffle plate 13, and the lower part of the No. 2 baffle plate 24 is axially staggered with the upper part of the lower baffle plate 13.

[0039] When the bubbles are concentrated on the upper inner wall of the cylinder 7 and the position of the upper baffle plate 14, the telescopic rod 22 drives the first baffle plate 23 and the second baffle plate 24 to intermittently approach the corresponding lower baffle plate 13 (such as Figure 6 As shown, at this time, the slide plate 16 has not moved up), thereby extending the lower baffle plate 13 to a certain extent, so that part of the water flowing through the upper side of the lower baffle plate 13 will flow through the upper side of the second baffle plate 24, thereby making the water flow contact and stir the above-mentioned bubbles, causing the bubbles to move, concentrate, and overlap, so that the corresponding heat exchange tube 10 intermittently increases the contact area with the cooling water. At the same time, in the process of the above-mentioned part of the water flow flowing through the upper side of the second baffle plate 24, the flow rate of the water flow is accelerated, and the water flow with the accelerated flow rate contacts the bubbles, thereby This makes it easier for the bubbles to be driven downward, and then gradually pass through the tortuous channel and flow out of the water outlet pipe 12. Through this action, the contact area between the corresponding heat exchange tube 10 and the cold water is increased. In addition, when the subsequent slide plate 16 moves upward, the water flow flowing through the upper side of the second baffle plate 24 is closer to the bubbles, making it easier for the water flow to drive the above-mentioned bubbles to move toward the water outlet pipe 12, thereby shortening the upward movement time of the slide plate 16 and reducing the amount of cooling water that does not pass through the tortuous channel but directly crosses the baffle 14, so that the heat of the discharged water is less affected.
