Utility Model Content

[0004] The purpose of the utility model is to provide a high-temperature kiln heat recovery device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A heat recovery device for a high-temperature kiln comprises a bracket, a water tank is fixedly connected above the bracket, a motor is fixedly connected to one side of the bracket, a pulley is fixedly connected to the output end of the motor, a plurality of ventilation pipes are evenly arranged in a circumferential direction in the water tank, the ventilation pipes are rotatably connected to the water tank, an air outlet pipe is arranged above the water tank, the other end of the air outlet pipe is connected to a flue gas treatment device, an air inlet pipe is arranged below the water tank, both the air outlet pipe and the air inlet pipe are rotatably connected to the ventilation pipe, a clamping plate is fixedly connected in the water tank, the ventilation pipe is rotatably connected to the clamping plate, a control component for controlling the rotation of the ventilation pipe is connected in the water tank, and a stirring component for stirring water is connected in the water tank.

[0007] When it is necessary to recover the heat energy in the high-temperature flue gas generated by the operation of the kiln, the high-temperature flue gas enters from the air inlet pipe, transfers heat through the ventilation pipe, and is then discharged from the air outlet pipe to the flue gas treatment equipment. In this process, the heat in the flue gas is transferred to the water through the ventilation pipe. When the high-temperature flue gas passes through the ventilation pipe, the control device starts working under the drive of the motor, so that the ventilation pipe is in a rotating state, thereby improving the efficiency of the flue gas heat transfer. At the same time, the stirring component starts working under the drive of the motor, so that the water in the water tank is in uniform contact with the outer wall of the ventilation pipe, thereby improving the efficiency of heat transfer without causing harm to the environment and human body.

[0008] A further improvement of the technical solution of the utility model is that the control component includes a rotating shaft, the rotating shaft is rotatably connected to the water tank, a pulley is fixedly connected to the rotating shaft, the pulley is located below the water tank, the pulleys are connected by belt transmission, a driving gear is fixedly connected to the end of the rotating shaft away from the water tank, a driven gear is fixedly connected to the ventilation pipe, and the driven gear is meshed with the driving gear.

[0009] The above technical solution is adopted. In this solution, when the control component is working, the motor will drive the pulley fixedly connected to its output end to rotate, and then the power will be transmitted to the rotating shaft through the cooperation of the belt and the pulley. The transmission shaft will drive the driving gear fixedly connected to it to rotate, and then the power will be transmitted to the ventilation pipe through its meshing driven gear, so that the ventilation pipe rotates, thereby achieving the purpose of improving the heat transfer efficiency, while also better protecting the environment and preventing harmful gas from overflowing.

[0010] A further improvement of the technical solution of the utility model is that the stirring component includes a transmission shaft, the transmission shaft is located at the end of the rotating shaft away from the pulley, the transmission shaft is fixedly connected to the rotating shaft, a plurality of spiral blades are evenly arranged along the circumferential direction of the transmission shaft, and the spiral blades are fixedly connected to the transmission shaft.

In this way, the water can be in uniform contact with the ventilation pipe, thereby improving the efficiency of heat transfer.

[0012] A further improvement of the technical solution of the utility model is that an auger is arranged inside the ventilation pipe, and the auger is fixedly connected to the air outlet pipe.

[0013] The above technical solution is adopted, in which an auger is arranged inside the ventilation pipe because the high-temperature flue gas contains a large amount of dust particles. If these dust particles adhere to the inner wall of the ventilation pipe, the efficiency of heat transfer between the flue gas and water will be greatly affected. The auger can scrape off the dust particles adhered to the inner wall of the ventilation pipe when the ventilation pipe rotates, thereby preventing the efficiency of heat transfer between the flue gas and water from being affected by the adhesion of dust particles.

[0014] A further improvement of the technical solution of the utility model is that temperature sensors are arranged inside the air inlet pipe and the air outlet pipe, and the temperature sensors are fixedly connected to the air inlet pipe and the air outlet pipe respectively.

[0016] A further improvement of the technical solution of the utility model is that the temperature sensor and the motor are electrically connected to the external control device.

[0017] By adopting the above technical solution, the configuration in this solution can facilitate the adjustment of the working state of the motor through the data of the temperature sensor, thereby improving the efficiency of heat transfer between the flue gas and water.

[0018] A further improvement of the technical solution of the utility model is that the material of the ventilation pipe is copper.

[0019] The above technical solution is adopted. In this solution, the material of the ventilation pipe is copper because copper has high thermal conductivity and is relatively easy to process.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

At the same time, the stirring component starts to work under the drive of the motor, so that the water in the water tank is in uniform contact with the outer wall of the ventilation pipe, thereby improving the efficiency of the heat transfer, and at the same time will not cause harm to the environment and human body.

[0033] In this embodiment, when it is necessary to recover the heat energy in the high-temperature flue gas generated by the operation of the kiln, the high-temperature flue gas enters from the air inlet pipe 6, transfers heat through the ventilation pipe 5, and then is discharged from the exhaust pipe 7 to the flue gas treatment equipment. In this process, the heat in the flue gas is transferred to the water through the ventilation pipe 5. When the high-temperature flue gas passes through the ventilation pipe 5, the control device starts working under the drive of the motor 3, so that the ventilation pipe 5 is in a rotating state, thereby improving the efficiency of the flue gas heat transfer. At the same time, the stirring component starts working under the drive of the motor 3, so that the water in the water tank 2 is in uniform contact with the outer wall of the ventilation pipe 5, thereby improving the efficiency of the heat transfer, and at the same time will not cause harm to the environment and human body.

[0035] When the control component is working, the motor 3 will drive the pulley 4 fixedly connected to its output end to rotate, and then the power will be transmitted to the rotating shaft 9 through the cooperation of the belt and the pulley 4. The transmission shaft 12 will drive the driving gear 10 fixedly connected to it to rotate, and then the power will be transmitted to the ventilation pipe 5 through its meshing driven gear 11, so that the ventilation pipe 5 rotates, thereby achieving the purpose of improving the heat transfer efficiency, while also better protecting the environment and preventing harmful gas from overflowing.

[0038] like Figure 3 , Figure 5 As shown, based on Example 1, the utility model provides a technical solution: preferably, an auger 14 is provided inside the ventilation pipe 5, and the auger 14 is fixedly connected to the air outlet pipe 7.

[0039] In the present embodiment, the auger 14 is provided inside the ventilation pipe 5 because the high-temperature flue gas contains a large amount of dust particles. If these dust particles adhere to the inner wall of the ventilation pipe 5, the efficiency of heat transfer between the flue gas and water will be greatly affected. The auger 14 can scrape off the dust particles adhered to the inner wall of the ventilation pipe 5 when the ventilation pipe 5 rotates, thereby preventing the efficiency of heat transfer between the flue gas and water from being affected by the adhesion of dust particles.

[0041] In this embodiment, by providing the temperature sensor 15, the efficiency of heat transfer between the flue gas and the water can be timely understood, so that the device can be adjusted to achieve the best efficiency of heat transfer.

[0044] like Figure 3 As shown, based on Example 3, the utility model provides a technical solution: preferably, the material of the ventilation pipe 5 is copper.

[0045] In this embodiment, the material of the ventilation pipe 5 is copper because copper has high thermal conductivity and is relatively easy to process.

[0046] The following is a detailed description of the working principle of the high temperature kiln heat recovery device.

[0047] like Figure 1-5As shown, when it is necessary to recover the heat energy in the high-temperature flue gas generated by the kiln operation, the high-temperature flue gas enters from the air inlet pipe 6, transfers heat through the vent pipe 5, and then is discharged from the air outlet pipe 7 to the flue gas treatment equipment. In this process, the heat in the flue gas is transferred to the water through the vent pipe 5. When the high-temperature flue gas passes through the vent pipe 5, the control device starts to work under the drive of the motor 3, so that the vent pipe 5 is in a rotating state, thereby improving the efficiency of flue gas heat transfer. At the same time, the stirring component starts to work under the drive of the motor 3, so that the water in the water tank 2 is in uniform contact with the outer wall of the vent pipe 5, thereby improving the efficiency of heat transfer, and at the same time, it will not cause harm to the environment and human body. When the control component is working, the motor 3 will drive the pulley 4 fixedly connected to its output end to rotate, and then the belt and the pulley 4 are used together to transfer power to the rotating shaft 9, and the transmission shaft 12 will drive the driving gear 10 fixedly connected to it to rotate, and then the power is transferred to the vent pipe 5 through the meshing driven gear 11, so that the vent pipe 5 rotates. When the rotating shaft 9 rotates, the power will be transmitted to the transmission shaft 12 fixedly connected thereto. The rotation of the transmission shaft 12 will drive the spiral blade 13 fixedly connected thereto to rotate, thereby achieving the purpose of stirring the water. The auger 14 is arranged inside the vent pipe 5 because the high-temperature flue gas contains a large amount of dust particles. If these dust particles adhere to the inner wall of the vent pipe 5, the efficiency of heat transfer between the flue gas and the water will be greatly affected. The auger 14 can be arranged to scrape off the dust particles adhered to the inner wall of the vent pipe 5 when the vent pipe 5 rotates. By arranging the temperature sensor 15, the efficiency of heat transfer between the flue gas and the water can be timely understood, so that the device can be adjusted to achieve the best efficiency of heat transfer. Such an arrangement can facilitate the adjustment of the working state of the motor 3 through the data of the temperature sensor 15, thereby improving the efficiency of heat transfer between the flue gas and the water. The material of the vent pipe 5 is set to copper because copper has high thermal conductivity and is relatively easy to process.

[0048] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
