Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery of roasting furnaces, in particular to a waste heat recovery device for roasting furnaces. Background Art

[0002] A roaster is a thermal equipment that performs heat treatment on carbon raw materials (such as coke, anthracite, etc.) at high temperatures to improve the properties of the raw materials. It is widely used in ironmaking, rare metal recovery, catalyst production, environmental improvement, and the production of specialty chemicals. The flue gas generated by the roaster is generally discharged directly into the air, wasting resources. Therefore, a roaster waste heat recovery device is used to recover the heat in the flue gas discharged by the equipment.

[0003] Existing technologies such as the patent publication number CN212843003U disclose a waste heat collection device for the flue of a roasting furnace, which adopts a smoke exhaust pipe and a waste heat recovery pipe; the smoke exhaust pipe includes a smoke exhaust pipe body, a first smoke exhaust pipe joint and a second smoke exhaust joint, the first smoke exhaust pipe joint and the second smoke exhaust joint are respectively arranged on both sides of the smoke exhaust pipe body and connected to the furnace hole of the roasting furnace; the waste heat recovery pipe is arranged in the middle of the smoke exhaust pipe body and a guide channel is laid in a ring shape inside the waste heat recovery pipe; the utility model equipment solves the problem of low waste heat utilization rate in the existing roasting furnace, and since the roasting furnace flue is directly arranged on the furnace hole, there is a certain gap between the roasting furnace flue and the furnace hole, which makes the roasting furnace flue poorly sealed, resulting in a large amount of heat loss and increased energy consumption of the roasting furnace.

[0004] In daily work, when equipment discharges flue gas, some existing equipment directly discharges the flue gas during combustion into the air, which not only pollutes the environment, but also improves greenhouse efficiency, causing environmental pollution and wasting resources. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that it is difficult for equipment to recover heat in the discharged flue gas, and to propose a roasting furnace waste heat recovery device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a roasting furnace waste heat recovery device, including a pipe, a support frame, a base and a flange, the surface of the pipe is fixedly connected to the support frame, the lower surface of the support frame is fixedly connected to the base, one end of the pipe is fixedly connected to the flange, and a collecting device is arranged inside the pipe, the collecting device includes a threaded pipe and a connecting head, the connecting head is fixedly connected to the side of the pipe, the threaded pipe is located inside the pipe, one end of the threaded pipe is fixedly connected to a water inlet pipe, the water inlet pipe is arranged inside the connecting head, the end of the threaded pipe away from the water inlet pipe is fixedly connected to the air outlet pipe, the end of the water inlet pipe away from the threaded pipe is fixedly connected to a water tank, and the upper surface of the water tank is fixedly connected to a pump.

[0007] Furthermore, a water supply pipe is fixedly connected to the upper surface of the water tank, and a converter is provided at the end of the air outlet pipe away from the threaded pipe. By providing the converter, high-pressure water vapor can be converted into mechanical kinetic energy, thereby reducing the situation where the high-pressure water vapor is difficult to convert into mechanical kinetic energy when the equipment is in use, causing the equipment to generate electricity.

[0008] Furthermore, an air outlet is provided on the side of the converter, and a generator is provided on the side of the converter. The generator is provided to facilitate conversion of the power generated by the converter into electrical energy.

[0009] Furthermore, a storage device is provided on the surface of the generator, and the generator is fixedly connected to the side of the water tank. The storage device is provided to facilitate storage of the electrical energy generated by the generator.

[0010] Furthermore, an auxiliary component is provided inside the pipe, and the auxiliary component includes a connecting frame and an inclined plate. The connecting frame is fixedly connected to the inside of the pipe, and the inclined plate is arranged inside the pipe. A connecting ring is fixedly connected to the inside of the inclined plate, and the inside of the connecting ring is fixedly connected to a limiting frame. By providing the inclined plate, the path of the smoke entering the pipe can be changed, which reduces the situation where it is difficult for the smoke to move along the prescribed path when entering the pipe when the equipment is in use, making it difficult for the smoke to fully contact the surface of the threaded pipe.

[0011] Furthermore, the limiting frame is rotatably connected to the surface of the connecting frame, and one end of the limiting frame is fixedly connected to a wind-breaking block.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] In the utility model, a collection device is provided. When the device is in use, the user connects the burning flue gas to the pipe, and then the pump runs to allow the water in the water tank to enter the inside of the threaded pipe. Then the high temperature of the flue gas evaporates the water in the threaded pipe into high-temperature water vapor, and then the water vapor enters the inside of the converter through the outlet pipe to generate electricity for the generator. Then the water vapor is discharged through the outlet. After the generator generates electricity, it enters the storage for storage. By providing a collection device, the heat in the flue gas inside the pipe is effectively recovered, which plays a role in recovering and converting the high temperature in the flue gas, reducing the risk of general equipment directly discharging the flue gas during combustion into the air when the device is in use. This not only pollutes the environment, but also improves the greenhouse efficiency, causing environmental pollution and wasting resources. The collection device can recover the heat in the flue gas and store it as electrical energy, thereby improving the resource recovery of the equipment.

[0014] In the utility model, by setting an auxiliary component, when the device is in use, the smoke enters the interior of the pipe, and then the smoke is separated by the wind-breaking block, and then the smoke drives the connecting ring and the limit frame to rotate on the surface of the connecting frame through the inclined plate, and then the inclined plate rotates the smoke entering the interior of the pipe to the outlet to fully contact the surface of the threaded pipe. By setting the auxiliary component, the smoke entering the interior of the pipe is effectively separated, and the smoke is rotated and moved, which reduces the situation that when the device is in use, the smoke enters the interior of the pipe, and the smoke has an irregular route inside the pipe, which easily makes it difficult for the smoke to fully contact the surface of the threaded pipe, making it difficult for the device to fully recover the heat in the smoke. The auxiliary component can change the smoke entering the interior of the pipe to move threadably, and can fully contact the surface of the threaded pipe, thereby improving the practicality of the device.

[0021] The specific configuration and functions of the collecting device 5 and the auxiliary component 6 will be described in detail below.

[0022] In this embodiment: a collecting device 5 is provided inside the pipeline 1, and the collecting device 5 includes a threaded tube 51 and a connector 52. The connector 52 is fixedly connected to the side of the pipeline 1, and the threaded tube 51 is arranged inside the pipeline 1. One end of the threaded tube 51 is fixedly connected to a water inlet pipe 54. The water inlet pipe 54 is arranged inside the connector 52. The end of the threaded tube 51 away from the water inlet pipe 54 is fixedly connected to an air outlet pipe 55. The end of the water inlet pipe 54 away from the threaded tube 51 is fixedly connected to a water tank 53, and the upper surface of the water tank 53 is fixedly connected to a pump 511.

[0023] Specifically, a water supply pipe 510 is fixedly connected to the upper surface of the water tank 53 , and a converter 56 is provided at one end of the air outlet pipe 55 away from the threaded tube 51 .

[0024] In this embodiment, by providing a converter 56, high-pressure steam can be converted into mechanical kinetic energy, thereby reducing the difficulty of converting high-pressure steam into mechanical kinetic energy when the device is in use, causing the device to generate electricity.

[0025] Specifically, an air outlet 57 is provided on the side of the converter 56 , and a generator 58 is provided on the side of the converter 56 . The generator 58 is provided to facilitate conversion of the power generated by the converter 56 into electrical energy.

[0026] Specifically, a storage device 59 is provided on the surface of the generator 58 . The generator 58 is fixedly connected to the side of the water tank 53 . The storage device 59 is provided to store the electrical energy generated by the generator 58 .

[0027] In this embodiment: an auxiliary component 6 is provided inside the pipeline 1, and the auxiliary component 6 includes a connecting frame 61 and an inclined plate 62. The connecting frame 61 is fixedly connected to the inside of the pipeline 1, and the inclined plate 62 is arranged inside the pipeline 1. The interior of the inclined plate 62 is fixedly connected to a connecting ring 63, and the interior of the connecting ring 63 is fixedly connected to a limiting frame 65.

[0028] In this embodiment: by setting the inclined plate 62, the path of the smoke entering the interior of the pipe 1 can be changed, thereby reducing the situation where the smoke entering the interior of the pipe 1 is difficult to move along the prescribed path when the equipment is in use, making it difficult for the smoke to fully contact the surface of the threaded pipe 51.

[0029] Specifically, the limiting frame 65 is rotatably connected to the surface of the connecting frame 61 , and one end of the limiting frame 65 is fixedly connected to the wind-breaking block 64 .

[0030] Working principle: When the equipment is in use, the user connects the burning flue gas to the pipe 1, and then the pump 511 runs to let the water in the water tank 53 enter the inside of the threaded pipe 51, and then the high temperature of the flue gas evaporates the water in the threaded pipe 51 into high-temperature water vapor, and then the water vapor enters the inside of the converter 56 through the outlet pipe 55 to generate electricity for the generator 58, and then the water vapor is discharged through the outlet 57. After the generator 58 generates electricity, it enters the storage 59 for storage. By setting up the collection device 5, the heat in the flue gas inside the pipe 1 is effectively recovered, which plays a role in recovering and converting the high temperature in the flue gas, reducing the equipment in use. Generally, the equipment directly discharges the flue gas during combustion into the air, which not only pollutes the environment, but also improves the greenhouse efficiency, causing environmental pollution and wasting resources. The collection device 5 can recover the heat in the flue gas and store it into electrical energy, thereby improving the resource recovery of the equipment.

[0031] When the device is in use, the flue gas enters the interior of the pipe 1, and then the flue gas is separated by the wind-breaking block 64, and then the flue gas drives the connecting ring 63 and the limit frame 65 to rotate on the surface of the connecting frame 61 through the inclined plate 62, and then the inclined plate 62 rotates the flue gas entering the interior of the pipe 1 to be discharged and fully contacted with the surface of the threaded pipe 51. By setting up the auxiliary component 6, the flue gas entering the interior of the pipe 1 is effectively separated, and the role of rotating the flue gas is played, which reduces the situation when the device is in use. When the flue gas enters the interior of the pipe 1, the flue gas's travel route inside the pipe 1 is irregular, which easily makes it difficult for the flue gas to fully contact the surface of the threaded pipe 51, making it difficult for the device to fully recover the heat in the flue gas. The auxiliary component 6 can change the flue gas entering the interior of the pipe 1 to be threaded and can fully contact the surface of the threaded pipe 51, thereby improving the practicality of the device.
