Description

Technical Field

[0001] The utility model relates to the field of heat exchange, in particular to an integrated heat exchange device. Background Art

[0002] The high-temperature flue gas discharged by the high-power diesel engine used in the ground heating and air conditioning vehicle contains a large amount of heat, smoke and water vapor. Directly discharging it into the air will cause considerable energy waste and affect the environment.

[0003] In order to recycle this part of heat and avoid the direct emission of smoke and dust affecting the environment, it is necessary to design a device that can not only perform preliminary treatment of the smoke and dust, but also perform heat exchange to avoid energy waste and smoke and dust pollution.

[0004] Therefore, how to design a heat exchange device for high-temperature flue gas discharged from a high-power diesel engine used in a hot air air-conditioning vehicle, and a heat exchange device that can settle the flue dust is a problem that needs to be solved at present. Utility Model Content

[0006] Technical solution: An integrated heat exchange device, comprising:

[0007] The volute includes a smoke chamber and an air chamber that are independent of each other. The design of the volute makes the gas flow in a vortex shape, which increases the flow time and improves the heat exchange effect;

[0008] The flue comprises a smoke inlet communicating with the smoke chamber, a pipe body connected with the smoke chamber, and a smoke outlet communicating with the pipe body;

[0009] an air duct, comprising an air inlet communicating with the air cavity, and an air outlet communicating with the air cavity;

[0010] The smoke inlet is communicated with the exhaust end of the diesel engine.

[0011] The utility model is designed to connect the smoke chamber and the air chamber respectively by designing the flue and the air duct. During heat exchange, the smoke enters the smoke chamber through the smoke inlet, exchanges heat through the tube body, and is then discharged from the smoke outlet. The air enters the air chamber through the air inlet for heat exchange, and is then discharged to a predetermined position through the air outlet, thereby completing energy recovery. At the same time, a settling chamber is designed, and the rapid change of the spatial volume is utilized to sharply reduce the flow rate of the smoke entering the settling chamber. The purpose is to allow the smoke to fully exchange heat with the tube body while also allowing the smoke dust and water vapor carried by the smoke to be fully settled and separated.

[0012] The noise is also effectively reduced due to the dual attenuation effects of volume expansion and the honeycomb tube composed of multiple tubes.

[0013] In a further embodiment, the tube is provided in at least one piece and has a predetermined shape.

[0014] The tube body can be designed to be serpentine to increase the air flow time, thereby increasing the heat exchange effect. When multiple groups of tube bodies are designed, heat can be absorbed faster, so that the dust in the smoke can fall into the settling chamber.

[0015] In a further embodiment, a sedimentation chamber is provided at the bottom of the volute, and the sedimentation chamber is communicated with the smoke cavity and the pipe body.

[0016] In a further embodiment, the tube is disposed in the air cavity.

[0017] In a further embodiment, the air inlet is arranged on the side of the volute, and the air outlet is arranged above the volute;

[0018] The smoke inlet is located above the settling chamber and the air inlet.

[0019] In a further embodiment, the volume of the sedimentation chamber is larger than the smoke cavity and the portion where the smoke cavity is connected to the sedimentation chamber.

[0020] This application integrates smoke exhaust, silencer, dust removal and heat exchange, and can complete silencer and dust removal while avoiding waste of resources through an integrated heat exchange device.

[0021] Beneficial effect: The utility model discloses an integrated heat exchange device, which is connected to the smoke chamber and the wind chamber respectively by designing a flue and an air duct. During heat exchange, the smoke enters the smoke chamber through the smoke inlet, exchanges heat through the tube body, and is discharged from the smoke outlet. The air enters the wind chamber through the air inlet for heat exchange, and is discharged to a predetermined position through the air outlet, thereby completing energy recovery. At the same time, a sedimentation chamber is designed, and the rapid change of the spatial volume is used to sharply reduce the flow rate of the smoke entering the sedimentation chamber. The purpose is to allow the smoke to fully exchange heat with the tube body while also allowing the smoke dust and water vapor it carries to be fully settled and separated.

The air enters the wind chamber 23 through the air inlet 21 for heat exchange, and is discharged to a predetermined position through the air outlet 22, thereby completing energy recovery. At the same time, a settling chamber 4 is designed, and the rapid change of the spatial volume is utilized to sharply reduce the flow rate of the smoke entering the settling chamber 4. The purpose is to allow the smoke to fully exchange heat with the tube body 14 while also allowing the smoke and water vapor it carries to be fully settled and separated.
