Description

Technical Field

[0001] This utility model relates to the field of environmental protection and energy-saving equipment technology, and in particular to an air energy recovery system for high-temperature factory buildings. Background Technology

[0002] In the steel smelting industry, environmental regulations require industrial plants to be completely sealed. In high-temperature smelting plants such as those for copper and steel smelting, the molten metal often exceeds 1000°C. Heat radiation from the molten metal and furnace causes indoor temperatures to frequently exceed 60°C. These plants typically house equipment such as converters and overhead cranes. The electrical equipment within these systems is exposed to such high temperatures for extended periods, increasing the likelihood of equipment failure. Furthermore, maintenance and emergency repairs are impossible in such high-temperature environments. Additionally, the large size of the workshops prevents the use of air conditioning or other cooling systems. The inability to effectively recover a significant amount of heat easily leads to energy waste and severely impacts normal production.

[0003] Given the current situation where high indoor temperatures in high-temperature smelting plants severely affect the normal operation of equipment, the large plant area makes it impossible for air conditioning and other systems to cool the plants, and a large amount of heat is not being recovered and utilized, it is of great significance to design a simple, efficient, and highly operable heat recovery device to ensure stable equipment operation, a pleasant on-site environment, and energy conservation. Utility Model Content

The air energy recovery module includes a fan inlet pipe, a fan outlet pipe, a heat exchanger, a fan, a demineralized water inlet pipe, and a demineralized water outlet pipe. The demineralized water inlet pipe and the demineralized water outlet pipe are connected to the heat exchanger. The fan inlet pipe passes through the heat exchanger and is connected to the fan. The fan outlet pipe is connected to the output port of the fan. The inlet of the fan inlet pipe and the outlet of the fan outlet pipe are both installed on the inner wall of the high-temperature factory.

[0006] Furthermore, in this utility model, the inlet of the fan inlet pipe is located on the inner wall of the high-temperature workshop near the roof, and the outlet of the fan outlet pipe is located on the inner wall of the high-temperature workshop near the bottom.

[0007] Furthermore, the demineralized water inlet pipe of this utility model is filled with low-temperature demineralized water, while the demineralized water outlet pipe is filled with high-temperature demineralized water.

[0016] See Figure 1 This utility model is an air energy recovery system for a high-temperature factory, including a temperature measuring module, a controller, and an air energy recovery module. The temperature measuring module is installed on the side wall of the factory and transmits the measured temperature information to the controller in real time. The air energy recovery module includes a fan inlet pipe 8, a fan outlet pipe 3, a heat exchanger 6, a fan 4, a demineralized water inlet pipe 7, and a demineralized water outlet pipe 5. The demineralized water inlet pipe and the demineralized water outlet pipe are connected to the heat exchanger. The fan inlet pipe passes through the heat exchanger and is connected to the fan. Furthermore, the fan inlet pipe is equipped with an impurity filter screen 9 at its inlet, which contains a dust and impurity adsorption layer. The fan outlet pipe is connected to the output port of the fan. Both the inlet of the fan inlet pipe and the outlet of the fan outlet pipe are located on the inner wall of the high-temperature factory. Furthermore, in this invention, the inlet of the fan inlet pipe is located on the inner wall of the high-temperature workshop near the roof, and the outlet of the fan outlet pipe is located on the inner wall of the high-temperature workshop near the bottom. Furthermore, the demineralized water inlet pipe of this invention carries low-temperature demineralized water, and the demineralized water outlet pipe carries high-temperature demineralized water. Furthermore, the fan inlet pipe of this invention passes through the heat exchanger, and the portion of the fan inlet pipe within the heat exchanger is a spiral pipe. Furthermore, the temperature measuring module of this invention consists of several indoor thermometers 10, which are distributed on the inner walls of the high-temperature workshop 1. The temperature information measured by the indoor thermometers is communicatively connected to the controller. More precisely, the indoor thermometers are distributed on the walls surrounding the converter to monitor temperature changes near the converter in real time.

[0017] This system comprises multiple components. A blower is installed opposite the converter inside the plant, with its outlet angled towards the converter. A blower inlet pipe is installed near the roof opposite the converter. A heat exchanger is installed on the blower inlet pipe to exchange heat with the demineralized water. The blower delivers air convection, displacing the hot air around the converter. The heat exchanger then exchanges heat from the hot air with the demineralized water. This preheats the demineralized water entering the boiler, reducing the need for additional steam heating. This effectively recovers and reuses the heat lost from the air near the converter, reducing additional energy consumption.

[0018] After being cooled by the heat exchanger, the air is cooled down and then discharged into the high-temperature factory room to ventilate and cool the room, greatly improving the indoor air temperature and achieving good practical application results.

[0019] In addition, an impurity filter screen is installed on the inlet pipe of the fan. This impurity filter screen is mainly used to filter out some dust and impurities in the hot air absorbed by the pipe, so as to prevent impurities from being sucked into the fan. The dust and impurity adsorption layer here is usually made of porous materials (such as activated carbon and HEPA filter screen), which adsorb pollutants by utilizing the pore structure or surface chemical properties of the material, effectively adsorbing impurities or pollutants in the hot air.

[0020] The controller in this invention receives the temperature data from each indoor thermometer. Once the indoor temperature detected by any indoor thermometer reaches the threshold set in the controller, the controller will immediately instruct the fan to start working. At the same time, the external pump will also deliver the corresponding demineralized water for heat exchange.

[0021] This utility model's heat recovery system is simple in structure and easy to operate, effectively solving the problems of indoor cooling and heat recovery in high-temperature smelting plants. After its implementation, this utility model's heat recovery system is of great significance for ensuring the stable operation of converter smelting equipment, a pleasant operating environment, and energy conservation.
