Description

Technical Field

[0002] With the global attention paid to industrial pollution control, the supervision of waste gas emissions and energy efficiency has been strengthened. In industrial production, drying and sintering links are usually operated independently and have high energy consumption. Conventional equipment can only utilize 40% to 50% of energy, and a large amount of waste heat is directly discharged, causing energy waste. Integrated equipment shortens the production cycle and reduces labor and energy costs by integrating processes. The rise of drying and sintering equipment is the comprehensive result of environmental protection policies and industry needs. Its advantages are reduced energy consumption, controllable pollution and intensive processes. The existing drying and sintering integrated equipment has temperature fluctuations in the exhaust gas, and the recovered heat cannot stably supply the drying and sintering processes. There is a waste of heat energy by using high-temperature waste heat for low-temperature drying, resulting in low waste heat recovery efficiency. At the same time, the service life of the equipment is shortened in a high temperature and high humidity environment, and regular maintenance is required, which increases the cost of the equipment.

[0003] Patent CN106024984B discloses a drying sintering furnace and a drying sintering method. The above patent realizes a simple and easy implementation of the sintering method, which can prevent waste gas pollution control and make the exhaust gas reach a standard state. In addition, this sealed sintering process greatly improves the stability of sintering.

[0004] The above patent uses a first sintering furnace that can balance and control the temperature difference, and connects the upper furnace core and the lower furnace core of the first sintering furnace in a mirror-like manner to form a sealed silicon wafer conveying and sintering space, and controls the temperature difference between the temperature zone of the upper furnace core and the temperature zone of the lower furnace core, so that the temperature of the silicon wafer conveying and sintering space is maintained at a stable and balanced temperature difference value, and the temperature difference is less than 200°C. Through this sealed temperature control method, the influence of the outside world on the silicon wafer conveying and sintering space can be ignored, and there is room for optimization in the heat exchange process and heat exchange efficiency.

A visual sensor 21 is installed on the upper side of the outer wall of the material dividing plate 24. A purification component 5 is installed on the upper side of the outer wall of the drying component 4, and the purification component 5 is connected to the controller 2 through a signal line; The purification component 5 includes: a humidity sensor 26, a purifier 27, a moisture absorber 28 and a heat exchange tube 29, the humidity sensor 26 is connected to the controller 2 through a signal line, and the heat exchange tube 29 is connected to the water tank 12 through a connecting pipe; A purifier 27 is installed on the right side of the outer wall of the fan 16, a desiccant 28 is installed on the right side of the outer wall of the purifier 27, a humidity sensor 26 is installed on the right side of the outer wall of the desiccant 28, and a heat exchange tube 29 is installed on the upper side of the outer wall of the purifier 27; The purifier 27 includes: an absorption sheet 41, a fixture 42, an opening and closing valve 43 and an exhaust port 44, and the fixture 42 and the opening and closing valve 43 are connected to the controller 2 through a signal line; An absorption sheet 41 is installed on the right side of the outer wall of the fan 16, a fixer 42 is installed on the lower side of the outer wall of the absorption sheet 41, an opening and closing valve 43 is installed on the right side of the outer wall of the absorption sheet 41, and an exhaust port 44 is installed on the lower side of the outer wall of the opening and closing valve 43; Furthermore, after the processing is completed, the fan 16 is driven to rotate by the preheating motor 17, and the air valve 18 is controlled to connect the drying component 4 and the purification component 5, and the high-temperature exhaust gas inside the drying component 4 is transported into the purification component 5 through the connecting pipe. The moisture of impurities in the high-temperature exhaust gas is absorbed by the purifier 27 and the dehumidifier 28. The humidity of the treated exhaust gas is detected by the humidity sensor 26 and the information is transmitted to the controller 2.

When heat exchange is not required or the exhaust gas temperature is low and the heat exchange efficiency is low, after the exhaust gas is treated by the absorption sheet 41, the opening and closing valve 43 is opened to discharge the treated exhaust gas that meets the emission standards directly through the exhaust port 44, thereby realizing the function of harmless emission of high-temperature exhaust gas, solving the problem of exhaust gas pollution to the environment and exhaust gas damage to the equipment, reducing the pollution of the environment and the blockage of the equipment by harmful substances in the exhaust gas, improving the environmental protection and heat exchange efficiency of the equipment, and extending the service life of the equipment.

[0027] Example 5: Please refer to Figure 1 and Figure 2 , a drying and sintering integrated device for preparing waste heat recovery heat storage materials, the heat exchange component also includes a recovery module 11, and the recovery module 11 is connected to the first heat exchange layer 6 and the second heat exchange layer 7 through a connecting pipe; The recovery module 11 includes: a water tank 12, a heat storage tank 13, a water pump 14 and a heat absorber 15. The heat absorber 15 is connected to the heat storage tank 13 through a connecting pipe, the water pump 14 is connected to the heat exchange motor 9 through a connecting shaft, the heat absorber 15 is connected to the first heat exchange layer 6 and the second heat exchange layer 7 through a connecting pipe, and the water tank 12 is connected to the first heat exchange layer 6 and the second heat exchange layer 7 through the water pump 14; A heat absorber 15 is installed on the lower side of the outer wall of the second heat exchange layer 7, a heat storage tank 13 is installed on the lower side of the outer wall of the heat absorber 15, a water tank 12 is installed on the right side of the outer wall of the heat storage tank 13, and a water pump 14 is installed on the front side of the outer wall of the water tank 12; Furthermore, during the drying and sintering process, heat energy is accumulated in the heat storage tank 13 of the recovery module 11 by treating the high-temperature exhaust gas. When the material needs to be preheated, the air valve 18 is controlled to connect the heat exchange component and the preheating component 3, and the heat in the heat storage tank 13 is transferred to the preheating component 3 to preheat the material, thereby reducing energy consumption. When the working environment temperature of the equipment is low, the equipment can be preheated by transferring the heat energy stored in the heat storage tank 13 through the connecting pipe, and temperature compensation is performed on the temperature sensor 8, the humidity sensor 26 and the visual sensor 20 to avoid inaccurate data collection.

[0028] Working principle: Before drying and sintering the material, the material and the equipment need to be preheated. When preheating the equipment, the temperature inside the drying component 4 is increased by the hot air blower 39, and the temperature increase rate is 10℃ / min~15℃ / min. The temperature inside the drying component 4 is increased to 200℃. At the same time, the fan 16 is driven to rotate by the preheating motor 17, and the air valve 18 is opened to connect the drying component 4 and the preheating component 3. The high-temperature gas inside the drying component 4 is transported to the preheating component 3 through the connecting pipe to preheat the material. In the process of preheating the material, after the temperature inside the preheating component 3 is increased to 150℃~250℃, the stirring rod 19 is driven by the preheating motor 17 to stir the material so that the material is heated more evenly. After the preheating is completed, the air valve 18 is controlled to cancel the connection between the drying component 4 and the preheating component 3, and the air in the preheating component 3 is extracted by the fan 16. The humidity of the air is detected by the humidity sensor 26 to ensure that the moisture removal in the material meets the standard; After the material and the equipment are preheated, the material is transported to the drying component 4 through the workbench 1, and the drying component 4 is heated by the heater 21. When the material is dried, the material is heated by the infrared lamp 38, and the infrared radiation with a wavelength of 1μm to 3μm penetrates the surface of the material to quickly evaporate the water in the material to avoid high-temperature drying causing the surface of the material to crack. At the same time, the hot air convection with a wind speed of 1.5m / s to 3m / s is used to strengthen the drying of the material to avoid local overheating and decomposition of the material. When the material is sintered, the microwave polarization effect is used by the microwave device 40 to excite the vibration of the material molecules with a frequency of 2.45GHz, so that the temperature inside the material is uniformly increased. At the same time, during the sintering process, the visual sensor 20 collects information on the state of the material and transmits the information to the controller 2. The controller 2 determines the processing state of the material according to the received material information. When necessary, the drying motor 25 drives the rotating shaft 22 to rotate the material dividing plate 24, and the material is turned over to make the material heated more evenly. After the processing is completed, the fan 16 is driven to rotate by the preheating motor 17, and the air valve 18 is controlled to connect the drying component 4 and the purification component 5, and the high-temperature exhaust gas inside the drying component 4 is transported into the purification component 5 through the connecting pipe. The moisture of impurities in the high-temperature exhaust gas is absorbed by the purifier 27 and the dehumidifier 28. The humidity of the treated exhaust gas is detected by the humidity sensor 26 and the information is transmitted to the controller 2. During the exhaust gas purification process, the exhaust gas is heat exchanged through the heat exchange tube 29 to avoid damage to the purification component 5 caused by the high-temperature exhaust gas, and at the same time, the heat loss of the high-temperature exhaust gas during the transportation process is reduced. The absorption sheet 41 of the purifier 27 is used for the impurities in the exhaust gas. After the absorption of the substance, the absorption sheet 41 needs to be replaced. By canceling the fixing effect of the fixer 42, the absorption sheet 41 is taken out for replacement. After the replacement is completed, the fixing effect of the fixer 42 is restored. When the heat energy of the high-temperature exhaust gas is recovered, the impurities in the exhaust gas are absorbed by the purifier 27 to prevent the high-temperature exhaust gas containing impurities from directly entering the first heat exchange layer 6 and the second heat exchange layer 7 through the connecting pipe to damage the heat storage material installed in the inner layer 31. When heat exchange is not required or the temperature of the exhaust gas is low and the heat exchange efficiency is low, after the exhaust gas is processed by the absorption sheet 41, the opening and closing valve 43 is opened to discharge the treated exhaust gas that meets the emission standards directly through the exhaust port 44; During the operation of the equipment, high-temperature exhaust gas is generated. The high-temperature exhaust gas passes from the drying component 4 to the heat exchange component through the connecting pipe. The temperature sensor 8 detects the temperature of the exhaust gas and transmits the temperature information of the exhaust gas to the controller 2. The controller 2 controls the flow direction of the exhaust gas according to the received temperature information. When the temperature is in the range of 80°C to 200°C, the controller 2 controls the magnetic induction coil 45 to connect the power supply to provide power to the push rod 46 so that it pushes the push block 23 to connect the sealing ring 47 with the first heat exchange layer 6, and recovers heat energy through the heat storage material stored in the inner layer 31 of the first heat exchange layer 6. At the same time, the cooling water in the water tank 12 and the cooling water in the outer layer 30 of the first heat exchange layer 6 are circulated through the water pump 14 to absorb the heat absorbed by the inner layer 31. The heat absorber 15 absorbs the heat of the circulated cooling water and stores it in the heat storage tank 13, completing the heat transfer to the first heat exchange layer 6. When the exhaust gas temperature is between 750°C and 120 When the temperature is within the range of 0°C, by canceling the connection between the adapter 34 and the first heat exchange layer 6, the heat exchange motor 9 drives the rotating gear 37 to rotate the adapter 34 to the position connected to the second heat exchange layer 7, and the controller 2 controls the adapter 34 to connect with the second heat exchange layer 7 to recover the heat in the exhaust gas. When rapid heat exchange is required, the controller 2 controls the second valve 36 to open, and connects the first heat exchange layer 6 and the second heat exchange layer 7 through the connecting port 35. At this time, the adapter 34 is connected to the second heat exchange layer 7 to complete the heat energy recovery of the exhaust gas. When it is necessary to preheat the material, the heat exchange component and the preheating component 3 are connected by controlling the air valve 18 to transport the heat in the heat storage tank 13 to the preheating component 3 to preheat the material. When the working environment temperature of the equipment is low, the equipment can be preheated by passing the heat energy stored in the heat storage tank 13 through the connecting pipe, and temperature compensation is performed on the temperature sensor 8, the humidity sensor 26 and the visual sensor 20.
