Description

Technical Field

[0001] The utility model relates to a waste heat recovery device, belonging to the technical field of heat exchangers. Background Art

[0002] Waste heat recovery device conducts heat in the exhaust gas so that the heat can be recovered, thereby achieving the purpose of recovering heat energy. Waste heat recovery device is often used in chemical, petroleum, power, food, electricity and public fitness facilities. For example, waste incineration power plants use the high-temperature exhaust gas generated when waste is burned to conduct heat in the exhaust gas, provide heating to nearby facilities that need heat energy, and thus reduce emissions.

[0003] A conventional waste heat recovery device transmits high-temperature exhaust gas into the waste heat recovery device and introduces normal temperature water into it. Through heat conduction, the normal temperature water can absorb the heat energy in the exhaust gas. However, there will be some impurities in the exhaust gas. In order to increase the recovery rate, the conventional waste heat recovery device will set the exhaust gas transmission pipe into the shape of a continuous bend pipe, which can easily cause the risk of impurity blockage.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a waste heat recovery device, which solves the problem of easy blockage caused by impurities in the prior art.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0007] A waste heat recovery device comprises a tube body, the outer surface of the tube body is fixedly connected to a connecting frame, a replacement mechanism is arranged inside the connecting frame, the inner surface of the connecting frame is fixedly connected to a heat insulation board, the outer surface of the heat insulation board is fixedly connected to a heat conducting plate, the inner wall of the connecting frame is fixedly connected to a heat conducting rod, a conversion mechanism is arranged below the connecting frame, and the outer surface of the connecting frame is fixedly connected to a heat insulation cover.

[0008] By adopting the above technical scheme, the pipe body can transport exhaust gas, and at the same time, the outer surface of the pipe body is provided with a thermal insulation coating, thereby reducing the waste of heat energy. The replacement mechanism can filter the exhaust gas when the waste heat of the exhaust gas is recovered, and can effectively intercept large particles of debris in the air. The connecting frame has a thermal insulation coating on the surface like the pipe body. The heat conducting rod enables the replacement mechanism to transfer heat energy to the conversion mechanism. The heat insulation cover can wrap the pipeline, which can further prevent the dissipation of heat energy.

[0009] The utility model is further configured as follows: the replacement mechanism comprises a connection plate, the outer surface of the connection plate is slidably connected to the outer surface of the connection frame, and the outer surface of the connection plate is fixedly connected with a handle.

[0010] By adopting the above technical solution, the connecting plate can be easily pulled out through the handle. At the same time, the outer surface of the connecting plate is also coated with a temperature-insulating coating, and the interior of the connecting plate has a good thermal conductive material.

[0011] The utility model is further configured as follows: a filter screen is fixedly connected to the outer surface of the connecting plate, a heat-conducting copper wire is installed on the outer surface of the filter screen, and the outer surface of the connecting plate located on the filter screen is made of a heat-conducting material.

[0012] By adopting the above technical solution, the filter can effectively intercept large particles of impurities in the air. When the impurities accumulate slightly, heat energy will also accumulate on the impurities. The surface of the filter is a thermally conductive copper wire that can conduct the heat energy on the impurities.

[0013] The utility model is further configured as follows: the conversion mechanism includes a heat exchange box, the outer surface of the heat exchange box is fixedly connected to the outer surface of the connecting frame, the inner top wall of the heat exchange box is fixedly connected with a fixing plate, the inner side of the heat exchange box is fixedly connected to the outer surface of the heat conducting rod, and the bottom end of the heat conducting rod is fixedly connected to the outer surface of the fixing plate.

[0014] By adopting the above technical solution, the heat exchange box can provide the main support for the connecting frame, and the fixing plate can receive the heat energy transferred from the heat conducting rod.

[0015] The utility model is further configured as follows: a heat sink is fixedly connected to the outer surface of the fixing plate, a curved pipe is fixedly connected to the inner side of the heat exchange box, and the outer surface of the curved pipe is in contact with the outer surface of the heat sink.

[0016] By adopting the above technical solution, the heat sink can effectively dissipate the heat energy of the fixed plate. Condensed water is filled inside the bent pipe, which can absorb the heat from the heat sink. At the same time, the heat exchange box is filled with distilled water, which can seamlessly transfer the heat energy to the bent pipe and transfer the heat energy into the condensed water through the bent pipe.

[0017] The utility model is further configured as follows: the outer surface of the fixed plate is fixedly connected to a square plate, the outer surface of the square plate and the outer surface of the bent pipe are in contact with each other, the outer surface of the square plate is fixedly connected to a heat conducting pipe, and the outer surface of the heat conducting pipe is fixedly connected to the inner side of the heat exchange box.

[0018] By adopting the above technical solution, the heat pipe can transfer the collected heat energy to the bent pipe through the fixed plate, and at the same time the square plate and the heat exchange box can provide the main support capacity for the heat pipe.

[0019] The utility model is further configured as follows: the outer surface of the heat conducting pipe is fixedly connected to the inner side of the pipe body, and the outer surface of the heat conducting pipe located inside the pipe body is provided with a heat dissipation groove.

[0020] By adopting the above technical solution, the heat sink can effectively transfer the heat energy in the exhaust gas and transmit the collected heat energy through the heat pipe.

[0021] The beneficial effects of the utility model are:

[0022] 1. The utility model cooperates with the pipe body, the replacement mechanism and the conversion mechanism. The pipe body can transport waste gas containing heat energy, and the replacement mechanism can intercept large particles of debris in the waste gas. By utilizing the characteristic that the debris accumulates heat in the waste gas, the waste heat in the waste gas can be absorbed by the debris and transferred to the conversion mechanism, so as to meet the waste heat recovery conditions and clean and intercept impurities in the waste gas. This solves the problem that conventional waste heat recovery devices set the waste gas transmission pipe into a continuous curved pipe shape in order to increase the recovery rate, which easily causes the risk of impurity blockage.

[0023] 2. The utility model adopts the design of the pipeline, the conversion mechanism and the connecting frame itself. The conversion mechanism can be mounted on the pipeline through the connecting frame, and then multiple sections can be mounted on the pipeline, so that the condensed water can fully absorb the waste heat, and the floor space occupied by the conventional waste heat recovery device is eliminated, and the installation can be more flexible, so that the overall use of the device is more convenient; BRIEF DESCRIPTION OF THE DRAWINGS
