Description

A device for recovering waste heat from a carbonization furnace Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a device for reusing waste heat from a carbonization furnace. Background Technology

[0002] During operation, carbonization furnaces produce flue gas carrying a large amount of heat energy. Waste heat recovery devices can use the high-temperature flue gas discharged from the carbonization furnace as a heat source to heat water. This hot water can be used for heating and hot water supply in daily life, greatly improving energy utilization.

[0003] When using a waste heat recovery device, the exhaust pipe of the carbonization furnace needs to be connected to the inlet pipe of the waste heat recovery device. Cold water enters the winding pipes inside the device through the water inlet pipe, and high-temperature flue gas enters the inner wall of the device through the inlet pipe. The cold water in the bend absorbs the heat in the flue gas and then discharges it through the water outlet pipe. The flue gas that has had its heat absorbed is discharged through the outlet pipe. However, when the high-temperature flue gas passes through the connection between the exhaust pipe of the carbonization furnace and the inlet pipe of the waste heat recovery device, it may escape from the gap at the connection, which may lead to heat loss and a decrease in energy utilization. Summary of the Invention

[0004] This utility model proposes a waste heat recovery device for a carbonization furnace to address the problem that when high-temperature flue gas passes through the connection between the exhaust pipe of the carbonization furnace and the inlet pipe of the waste heat recovery device, it may escape from the gap at the connection, which may lead to heat loss and a decrease in energy utilization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbonization furnace waste heat recovery device, comprising a shell, wherein a water inlet pipe and a water outlet pipe are fixedly installed symmetrically on one side of the shell at the bottom and top, an air inlet pipe is fixedly installed at one end of the shell, an exhaust pipe is provided on the inner wall of the air inlet pipe, a filter screen is installed on the inner wall of the air inlet pipe, one end of the exhaust pipe abuts against one side of the filter screen, and an auxiliary sealing device is provided between the air inlet pipe and the exhaust pipe, wherein the auxiliary sealing device seals the air inlet pipe and the exhaust pipe by setting a rubber ring abutting against the connection between the exhaust pipe and the air inlet pipe.

[0006] The effect achieved by the above components is as follows: by setting up a rubber airbag, the rubber airbag has a relatively good deformation capability. When the outer surface of the rubber airbag is completely in contact with the connection between the exhaust pipe and the intake pipe, the rubber airbag can seal the connection between the exhaust pipe and the intake pipe, which helps to prevent high-temperature flue gas from escaping from the connection between the exhaust pipe and the intake pipe and thus preventing heat waste.

[0007] Preferably, the auxiliary sealing device includes a cylinder, which is fixedly installed on one side of the housing and one end of the air intake pipe. A rubber airbag is provided between the cylinder and the exhaust pipe, with one side of the rubber airbag fixedly installed on one side of the air intake pipe. An external threaded cylinder is threadedly connected to the inner wall of the cylinder.

[0008] The effect achieved by the above components is as follows: rotating the external threaded cylinder causes it to move towards the rubber airbag on the inner wall of the cylinder, which in turn compresses the rubber airbag, causing it to deform until the outer surface of the rubber airbag is in complete contact with the outer surfaces of the intake and exhaust pipes, thus sealing the connection between the intake and exhaust pipes.

[0009] Preferably, a rubber ring is fixedly installed at one end of the external threaded cylinder near the rubber airbag.

[0010] The effect achieved by the above components is as follows: by setting a rubber ring, one end of the external threaded cylinder can be replaced to abut against one side of the rubber airbag, which can play a certain protective role for the rubber airbag and help prevent the external threaded cylinder from excessively squeezing the rubber airbag and causing damage to the rubber airbag. It should also be noted that both the rubber airbag and the rubber ring are made of fluororubber, which has high temperature resistance and can maintain good physical properties even in high temperature environments.

[0011] Preferably, an elastic ring is installed on the side of the inner wall of the airbag away from the external threaded cylinder, and one side of the elastic ring abuts against the other side of the rubber airbag.

[0012] The effect achieved by the above components is as follows: by setting up an elastic ring, when the external threaded cylinder drives the rubber ring to squeeze the rubber airbag, the elastic ring will also deform. Then, when the external threaded cylinder is rotated to make the rubber ring move away from the rubber airbag, the elastic ring will reset and assist the rubber airbag in resetting. This will release the rubber airbag from contact with the intake pipe and exhaust pipe, making it easier to separate the two.

[0013] Preferably, an auxiliary ring is fixedly installed at the other end of the external threaded cylinder, the outer surface of the auxiliary ring is uniformly provided with protrusions, and the exhaust pipe is disposed inside the auxiliary ring.

[0014] The effect achieved by the above components is as follows: by setting the auxiliary ring, rotating the auxiliary ring can drive the external threaded cylinder to rotate. At the same time, the outer surface of the auxiliary ring is provided with protrusions, which can effectively increase the friction of the outer surface of the auxiliary ring and have an anti-slip effect when rotating the auxiliary ring.

[0015] Preferably, four round rods are evenly fixedly installed on one side of the auxiliary ring, and the same ring is slidably installed on the outer surface of the four round rods, and the ring is rotatably installed on the outer surface of the intake pipe.

[0016] The effect achieved by the above components is as follows: when the external threaded cylinder is rotated by the auxiliary ring, the ring connected to the round rod will rotate on the outer surface of the air intake pipe. At the same time, when the threaded cylinder extends and retracts on the inner wall of the cylinder, it will drive the round rod to slide synchronously on the inner wall of the ring, which makes the movement of the external threaded cylinder on the inner wall of the cylinder more stable.

[0017] Preferably, four extension blocks are evenly fixedly installed on one side of the ring, the extension blocks are arranged between two adjacent extension blocks, and bolts are threaded into the inner wall of the extension blocks.

[0018] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt abuts against the cylinder, and the bolt can fix the ring and the cylinder, thereby fixing the external threaded cylinder. This helps to prevent the external threaded cylinder from loosening on the inner wall of the cylinder, which would cause the rubber airbag to loosen its seal on the air intake and exhaust pipes.

[0019] Preferably, a rubber block is fixedly installed at one end of the bolt near the cylinder.

[0020] The effect achieved by the above components is that by setting a rubber block to replace one end of the bolt in contact with the outer surface of the cylinder, the contact area and friction between the bolt and the cylinder can be increased, making the bolt more securely fixed to the external threaded cylinder.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a rubber airbag is provided. The rubber airbag has a good deformation capacity. When the outer surface of the rubber airbag is in complete contact with the connection between the exhaust pipe and the intake pipe, the rubber airbag can seal the connection between the exhaust pipe and the intake pipe, which helps to prevent high-temperature flue gas from escaping from the connection between the exhaust pipe and the intake pipe and thus preventing heat waste.

[0028] Example 1, referring to Figures 1-3, discloses a waste heat recovery device for a carbonization furnace, including a shell 1. A water inlet pipe 2 and a water outlet pipe 3 are fixedly installed symmetrically on the bottom and top of one side of the shell 1. An air inlet pipe 4 is fixedly installed at one end of the shell 1. An exhaust pipe 5 is provided on the inner wall of the air inlet pipe 4. A filter screen plate 7 is installed on the inner wall of the air inlet pipe 4. One end of the exhaust pipe 5 abuts against one side of the filter screen plate 7. An auxiliary sealing device 6 is provided between the air inlet pipe 4 and the exhaust pipe 5. The auxiliary sealing device 6 seals the connection between the exhaust pipe 5 and the air inlet pipe 4 by setting a rubber ring 64 that abuts against the connection between the exhaust pipe 5 and the air inlet pipe 4. By setting a rubber airbag 62, the rubber airbag 62 has a relatively good deformation capacity. When the outer surface of the rubber airbag 62 is completely abutted against the connection between the exhaust pipe 5 and the air inlet pipe 4, the rubber airbag 62 can seal the connection between the exhaust pipe 5 and the air inlet pipe 4, which helps to prevent high-temperature flue gas from escaping from the connection between the exhaust pipe 5 and the air inlet pipe 4 and thus preventing heat waste.

[0029] Referring to Figures 2 and 3, the auxiliary sealing device 6 includes a cylinder 61, which is fixedly installed on one side of the housing 1. The cylinder 61 is also fixedly installed at one end of the intake pipe 4. A rubber airbag 62 is disposed between the cylinder 61 and the exhaust pipe 5. One side of the rubber airbag 62 is fixedly installed on one side of the intake pipe 4. An external threaded cylinder 63 is threadedly connected to the inner wall of the cylinder 61. Rotating the external threaded cylinder 63 causes it to move towards the rubber airbag 62 along the inner wall of the cylinder 61, thus compressing the rubber airbag 62 and causing it to deform until the outer surface of the rubber airbag 62 is flush with the outer surface of the intake pipe 4 and the exhaust pipe 5. With the surfaces completely in contact, the rubber airbag 62 can seal the connection between the intake pipe 4 and the exhaust pipe 5. A rubber ring 64 is fixedly installed at one end of the external threaded cylinder 63 near the rubber airbag 62. By setting the rubber ring 64, one end of the external threaded cylinder 63 can be in contact with one side of the rubber airbag 62, which can play a certain protective role for the rubber airbag 62 and help prevent the external threaded cylinder 63 from excessively squeezing the rubber airbag 62 and causing the rubber airbag 62 to break. It should also be noted that both the rubber airbag 62 and the rubber ring 64 are made of fluororubber. Fluororubber has high temperature resistance and can maintain good physical properties even in high temperature environments.

[0030] Referring to Figures 2 and 3, an elastic ring 65 is installed on the side of the inner wall of the airbag away from the external threaded cylinder 63. One side of the elastic ring 65 abuts against the other side of the rubber airbag 62. By setting the elastic ring 65, when the external threaded cylinder 63 drives the rubber ring 64 to squeeze the rubber airbag 62, the elastic ring 65 will also deform. Then, when the external threaded cylinder 63 is rotated so that the rubber ring 64 moves away from the rubber airbag 62, the elastic ring 65 will reset and assist the rubber airbag 62 in resetting. This releases the rubber airbag 62 from the contact between the airbag 62 and the air inlet pipe 4 and the exhaust pipe 5, making it easier to separate the two. An auxiliary ring 66 is fixedly installed at the other end of the external threaded cylinder 63. The outer surface of the auxiliary ring 66 is evenly provided with protrusions. The exhaust pipe 5 is located inside the auxiliary ring 66. By setting the auxiliary ring 66, rotating the auxiliary ring 66 can drive the external threaded cylinder 63 to rotate. At the same time, the protrusions on the outer surface of the auxiliary ring 66 can effectively increase the friction of the outer surface of the auxiliary ring 66, which has an anti-slip effect when rotating the auxiliary ring 66.

[0031] Referring to Figures 2-4, four round rods 67 are evenly fixedly installed on one side of the auxiliary ring 66. The same ring 68 is slidably installed on the outer surface of the four round rods 67. The ring 68 is rotatably installed on the outer surface of the intake pipe 4. When the external threaded cylinder 63 is rotated by the auxiliary ring 66, the ring 68 connected to the round rods 67 will be driven to rotate on the outer surface of the intake pipe 4. At the same time, when the threaded cylinder extends and retracts on the inner wall of the cylinder 61, it will drive the round rods 67 to slide synchronously on the inner wall of the ring 68. This makes the movement of the external threaded cylinder 63 on the inner wall of the cylinder 61 more stable.

[0032] Referring to Figure 4, four extension blocks 69 are evenly fixedly installed on one side of the ring 68. The extension blocks 69 are positioned between two adjacent extension blocks 69. Bolts 610 are threaded into the inner wall of the extension blocks 69. By rotating the bolts 610, one end of the bolts 610 abuts against the cylinder 61, thus fixing the ring 68 and the cylinder 61, and consequently fixing the external threaded cylinder 63. This helps prevent the external threaded cylinder 63 from loosening on the inner wall of the cylinder 61, which could cause the seal of the rubber airbag 62 on the air inlet pipe 4 and the exhaust pipe 5 to loosen. A rubber block 611 is fixedly installed on one end of the bolt 610 near the cylinder 61. By setting the rubber block 611 to replace one end of the bolt 610 in abutting against the outer surface of the cylinder 61, the contact area and friction between the bolt 610 and the cylinder 61 can be increased, making the fixing of the bolt 610 to the external threaded cylinder 63 more stable.

[0033] Working principle: Rotating the auxiliary ring 66 causes the external threaded cylinder 63 to extend and retract on the inner wall of the cylinder 61. The auxiliary ring 66 causes the ring 68 connected to the round rod 67 to rotate on the outer surface of the intake pipe 4, and causes the round rod 67 to slide synchronously on the inner wall of the ring 68. Meanwhile, the external threaded cylinder 63 drives the rubber ring 64 to compress the rubber airbag 62 and the elastic ring 65, causing the rubber airbag 62 and the elastic ring 65 to deform until the outer surface of the rubber airbag 62 is completely in contact with the outer surfaces of the intake pipe 4 and the exhaust pipe 5. Thus, the rubber airbag 62 can connect the intake pipe 4 and the exhaust pipe 5. The four bolts 610 are rotated so that the rubber blocks 611 at one end of the bolts 610 abut against the outer surface of the cylinder 61, which can fix the external threaded cylinder 63. This helps to prevent the external threaded cylinder 63 from loosening on the inner wall of the cylinder 61, which would cause the seal of the rubber airbag 62 on the air inlet pipe 4 and the exhaust pipe 5 to loosen. When the external threaded cylinder 63 is rotated so that the rubber ring 64 moves away from the rubber airbag 62, the elastic ring 65 will reset and assist the rubber airbag 62 in resetting. This will release the rubber airbag 62 from abutting against the air inlet pipe 4 and the exhaust pipe 5, making it easier to separate the two.
