Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a composite heat exchanger. Background Art

[0002] Heat exchanger is an energy-saving device that realizes heat transfer between two or more fluids at different temperatures. It transfers heat from a higher temperature fluid to a lower temperature fluid, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization. The heat exchanger industry involves nearly 30 industries such as HVAC, pressure vessels, reclaimed water treatment equipment, chemicals, petroleum, etc., forming an industrial chain.

[0003] When the existing composite heat exchanger is in use, the heat exchange of the device uses a fan to directly inject cold air and high-temperature fluid for heat exchange. However, this method usually reduces the contact area between the cold air and the high-temperature fluid, resulting in more heat loss. Therefore, a composite heat exchanger is proposed. Summary of the invention

[0004] The present invention aims to solve the technical problem of how to increase the contact area between cold air and high-temperature fluid during heat exchange, thereby improving the efficiency of heat exchange, and provides a composite heat exchanger.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A composite heat exchanger comprises a first cylinder, a second cylinder, a box, a plurality of heat exchange tubes, a spray device, a heat exchange device, a swinging spoiler device and a controller.

[0010] The spray device is arranged on the upper part of the second cylinder, and the spray device is connected to the second cylinder.

[0011] The heat exchange device is arranged at the lower part of the second cylinder and below the spray device. The heat exchange device is connected to the second cylinder, the first cylinder and the spray device.

[0012] The swing spoiler device is arranged on the upper part of the box body and is located on the side of the heat exchange device. The swing spoiler device is connected to the box body, connected to the second cylinder body and connected to the heat exchange device.

[0013] The controller is arranged on the side of the box body away from the first cylinder body, the controller is fixedly connected to the box body, and the controller is electrically connected to the spray device and the heat exchange device respectively.

[0014] When using this equipment, the staff pours the medium fluid into the box body so that the medium fluid overflows the heat exchange tube. Then the staff passes the high-temperature fluid into the spray device so that the high-temperature fluid is sprayed out through the spray device. The sprayed high-temperature fluid exchanges heat with the cold air in the heat exchange device. After the first heat exchange, the high-temperature fluid enters the first cylinder body and performs a second heat exchange with the heat exchange tube to improve the heat exchange efficiency. During the second heat exchange, the swinging spoiler device accelerates the flow speed of the medium fluid, so that the medium fluid frequently enters the heat exchange tube to improve the heat exchange effect.

[0015] Furthermore, the spray device includes a wind tube, a dual-axis motor, a fan, a first gear, a first hollow tube, a second gear, and a spray pipe.

The staff starts the dual-axis motor through the controller, and one of the shafts of the dual-axis motor drives the fan to rotate. The rotation of the fan causes the cold air after heat exchange in the second cylinder to be discharged through the air port on the upper part of the wind tube to prevent the cold air after heat exchange from affecting the subsequent heat exchange effect. The other shaft of the dual-axis motor drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the first hollow tube to rotate, the first hollow tube drives the spray tube to rotate, the spray tube drives the two telescopic rods to rotate, and drives the spray port at the bottom of the spray tube to rotate, so that the high-temperature fluid is sprayed in a rotating manner, increasing the contact area between the high-temperature fluid and the cold air and improving the heat exchange efficiency.

The staff then controls the cylinder 16 to rise and fall through the controller 39. Due to the telescopic tube 15, the telescopic end of the cylinder 16 drives the jet pipe 17 to rise and fall, so that the jet pipe 17 can eject the cold air at different heights, so that the cold air in the second cylinder 2 is evenly distributed, thereby improving the heat exchange effect.

[0135] The three spoilers 22 swing up and down, which can move the medium fluid in the box 3 and the heat exchange tube 4, thereby increasing the flow speed of the medium fluid, so that the medium fluid can enter the heat exchange tube 4 more frequently, thereby improving the secondary heat exchange effect between the high-temperature fluid and the medium fluid in the heat exchange tube 4.

[0136] The three first rotating shafts 21 are evenly distributed vertically inside the box body 3 .

[0137] The spoiler 22 can effectively disturb the medium fluid in the box body 3 and the heat exchange tube 4.

[0138] The penetration points between the three first rotating shafts 21 and the box body 3 are all covered with sealing rings.

[0139] Prevent media fluid from spilling.

[0140] Working principle: When using this equipment, the staff opens the valve of the upper inlet of the box body 3, pours the medium fluid from the inlet into the box body 3, and makes the medium fluid overflow the heat exchange tube 4 and the spoiler 22. Then the staff closes the inlet valve and starts the air pump 18 through the controller 39. The air pump 18 draws external cold air through the pipeline. The cold air passes through the air inlet pipe 19, the rotating sleeve 12, the second hollow tube 13, the telescopic tube 15 in turn, enters the jet pipe 17, and then is ejected from the jet port of the jet pipe 17.

[0141] When it is necessary to spray high-temperature fluid, the staff will pass the high-temperature fluid into the pipe and rotary joint at the top of the first hollow tube 9, and then the high-temperature fluid will pass through the first hollow tube 9 and the spray pipe 11 in turn, and then be sprayed out from the spray port to exchange heat with the cold air.

[0143] When the spray pipe 11 drives the two telescopic rods 20 to rotate, the two telescopic rods 20 drive the jet pipe 17 to rotate, the jet pipe 17 drives the two cylinders 16 to rotate, the two cylinders 16 drive the circular plate 14 to rotate, the circular plate 14 drives the second hollow tube 13 to rotate, the second hollow tube 13 drives the first bevel gear 28 to rotate, and due to the rotation of the jet pipe 17, the cold air can be sprayed out in a rotating manner, thereby increasing the contact area with the high-temperature fluid and improving the heat exchange efficiency. The staff then controls the cylinder 16 to rise and fall through the controller 39. Due to the telescopic tube 15, the telescopic end of the cylinder 16 drives the jet pipe 17 to rise and fall, so that the jet pipe 17 can spray the cold air at different heights, so that the cold air in the second cylinder 2 is evenly distributed, thereby improving the heat exchange effect.

[0144] When the second hollow tube 13 drives the first bevel gear 28 to rotate, the first bevel gear 28 drives the second bevel gear 30 to rotate, the second bevel gear 30 drives the third rotating shaft 29 to rotate, the third rotating shaft 29 drives the third bevel gear 31 to rotate, the third bevel gear 31 drives the bevel gear ring 33 to rotate, the bevel gear ring 33 drives the rotating disk 32 to rotate, the rotating disk 32 drives the eccentric column 34 to rotate, the eccentric column 34 drives the connecting bar 35 to move left, the connecting bar 35 drives the sliding bar 37 to move left, the sliding bar 37 drives the first rack 38 to move left, the first rack 38 drives the fourth gear 27 to rotate forward, the fourth gear 27 drives the second rotating shaft 24 to rotate forward, the second rotating shaft 24 drives the topmost first roller 25 to rotate forward, the topmost first roller 25 drives the belt 26 to rotate forward, the belt 26 drives the three first rollers 25 below to rotate forward, the three first rollers 25 below respectively drive the three first rotating shafts 21 to rotate forward, and the three first rotating shafts 21 respectively drive the three spoilers 22 to swing downward.

[0145] When the eccentric column 34 drives the connecting bar 35 to move right, the connecting bar 35 drives the sliding bar 37 to move right, the sliding bar 37 drives the first rack 38 to move right, the first rack 38 drives the fourth gear 27 to rotate in the opposite direction, the fourth gear 27 drives the second rotating shaft 24 to rotate in the opposite direction, the second rotating shaft 24 drives the top first roller 25 to rotate in the opposite direction, the top first roller 25 drives the belt 26 to rotate in the opposite direction, the belt 26 drives the three first rollers 25 below to rotate in the opposite direction, the three first rollers 25 below respectively drive the three first rotating shafts 21 to rotate in the opposite direction, and the three first rotating shafts 21 respectively drive the three spoilers 22 to swing upward.

[0146] The three spoilers 22 swing up and down, which can move the medium fluid in the box 3 and the heat exchange tube 4, thereby increasing the flow speed of the medium fluid, so that the medium fluid can enter the heat exchange tube 4 more frequently, thereby improving the secondary heat exchange effect between the high-temperature fluid and the medium fluid in the heat exchange tube 4.

[0147] After a period of time, the staff opens the valve of the liquid outlet at the bottom of the first cylinder 1 to discharge the high-temperature fluid after heat exchange. Then the staff opens the valve of the outlet at the bottom of the box 3 to discharge the medium fluid.
