DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0022] The specific embodiments of the utility model are described below in combination with the drawings. Specific embodiment one:
[0024] Refer to Figures 1-4A multi-stage heat flow control heat exchange device includes an exchange tank 1. Both sides of the exchange tank 1 are bolted with sealing caps 7, and the sealing caps 7 and the exchange tank 1 are threadedly connected with fixing bolts 4. A baffle is provided between the sealing caps 7 and the heat exchange pipes 10. The connection between the sealing caps 7 and the heat exchange pipes 10 is sealed by sealing gaskets 11, and the space formed between the sealing caps 7 and the heat exchange pipes 10 serves as a buffer zone. Water inlet pipes 3 and water outlet pipes 8 are respectively provided at both ends of the exchange tank 1. Heat inlet pipes 2 and heat outlet pipes 6 are respectively provided on both sides of the top of the exchange tank 1. A movable orifice plate 12 is provided in the inner cavity of one side of the water inlet pipe 3, and a positioning groove is provided between the movable orifice plate 12 and the inner wall of the exchange tank 1. 13. The movable orifice plate 12 is slidably connected to the inner wall of the exchange tank 1 via the positioning groove 13. The inner cavity of the exchange tank 1 is provided with a heat exchange pipe 10. A positioning ring 9 is sleeved on the surface of the heat exchange pipe 10. Sealing gaskets 11 are sleeved on both ends of the heat exchange pipe 10. A main telescopic rod 14 and a pressure spring 15 are provided between one side of the movable orifice plate 12 and the inner wall of the exchange tank 1 at a horizontal position. The pressure spring 15 is horizontally positioned between the main telescopic rod 14 and the inner wall of the exchange tank 1. The movable orifice plate 12 and the positioning groove 13 are connected by a slide rail. The slide rail has an "I" shaped cross section. The main telescopic rod 14 is a double-segmented rod. One segment of the main telescopic rod 14 is positioned with the inner surface of the exchange tank 1. The telescopic section 4 and the pressure spring 15 are positioned relative to each other. During operation, liquid is introduced into the inlet pipe 3, and the liquid pressure is not entirely stable. The bottom of the moving orifice plate 12 is restricted by the pressure spring 15, thereby applying different surface pressures to the moving orifice plate 12 based on different inlet liquid pressures. This allows for adaptive changes in the size of the buffer zone formed by the sealing cover 7 and the end of the exchange tank 1. When the pressure is too high, since the moving orifice plate 12 is a perforated plate, most of the excess pressure can be transferred to the area near the bottom. The flow velocity in the bottom area will be slowed down by passing through the orifice plate, thus allowing the flow rate into the heat exchange pipe 10 in the top buffer zone to be faster, while the flow rate into the bottom buffer zone is slower. The flow rate into heat exchange pipe 10 is relatively slow. Since the heat exchange liquid enters through inlet pipe 2 and exits through outlet pipe 6, the calorific value at the top is higher than that at the bottom, thus achieving rapid flow at the top and faster heat exchange. The heat difference at the bottom is smaller, resulting in a slower heat exchange rate. Consequently, when the heat exchange liquid enters the buffer zone on one side of outlet pipe 8 after passing through heat exchange pipe 10, the uniform temperature difference in heat exchange is smaller, and the final output temperature of outlet pipe 8 is more stable and uniform, improving the efficiency of subsequent reactions. Under certain circumstances, the need for subsequent heat exchangers can be reduced. At the same time, by controlling the end heat exchange temperature, further chemical reactions can be achieved more quickly, reducing the preparation process.
[0025] The middle part of the top surface of the exchange tank body 1 is provided with a control host 5, the control host 5 is built-in wireless transceiver, different sensors can be added in the inside of the exchange tank body 1, including temperature, pressure, flow rate, flow and other sensors, the sensor data is transmitted to the control host 5, so that centralized control can be realized, centralized collection and analysis data, sensor data will also be transmitted to the cloud database through the wireless transceiver of the control host 5, remote data backup can be realized, and the intelligent level of the whole heat exchange tank is improved.
[0026] The ports of the hot inlet pipe 2, the water inlet pipe 3, the hot outlet pipe 6 and the water outlet pipe 8 are threaded ports, and the port diameters of the hot inlet pipe 2, the water inlet pipe 3, the hot outlet pipe 6 and the water outlet pipe 8 are the same, a unified interface size is adopted, the pipe can be adapted, the preparation of different accessories is reduced, the universality of parts is improved, and when installing and using, the preparation time can be further reduced, the construction efficiency is improved, and the cost of enterprises is reduced. Specific embodiment two:
[0028] Based on the technical scheme of the specific embodiment one, the hot inlet pipe 2, the water inlet pipe 3, the hot outlet pipe 6 and the water outlet pipe 8 are changed to flange structure, which can adapt to the current traditional pipe structure to a certain extent, but the flange structure has slightly high installation complexity and relatively poor maintenance convenience, but the improvement of the equipment is better in terms of improvement adaptability.
[0029] In summary:
[0030] 1. By moving the hole plate 12 and the pressure spring 15, the size of the buffer area can be automatically adjusted according to the inlet pressure. When the inlet pressure fluctuates, the moving hole plate 12 can displace according to the pressure change, ensuring that the flow rate of the top buffer area and the bottom buffer area is reasonable. The flow rate of the top buffer area is faster, which promotes the rapid passage of high-heat-value hot liquid through the heat exchange pipe 10, achieving efficient heat exchange. The flow rate of the bottom buffer area is slower, which makes the low-heat-value hot liquid stay in the heat exchange pipe 10 for a longer time, further improving the heat exchange effect.
[0031] 2. The ports of inlet heat pipe 2, inlet water pipe 3, outlet heat pipe 6, and outlet water pipe 8 adopt a unified thread and the same interface size, resulting in significant modularity and convenience. The unified interface size and thread design allow for the interchangeability of various pipes and fittings, reducing the need for preparing different accessories and improving the system's versatility and flexibility. The standardized interface design simplifies the installation process, reduces preparation time, and accelerates equipment construction efficiency. Simultaneously, the modular design facilitates on-site maintenance and component replacement, reducing equipment downtime and maintenance costs. By reducing the inventory and preparation of different accessories, it improves the economics of production and maintenance, and lowers the overall operating costs of the enterprise.
