Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to a heat energy recovery device for high-temperature liquid materials. Background Technology

[0002] In the chemical industry, many production processes generate large quantities of high-temperature liquid materials. These materials must be cooled before entering subsequent processes or storage to meet process requirements and storage conditions. However, existing cooling technologies have significant shortcomings, especially in heat utilization, resulting in serious energy waste.

[0003] Currently, the chemical industry commonly uses specialized cooling tanks to cool high-temperature liquid materials. This cooling method is based on the principle of heat exchange, allowing heat transfer between the high-temperature liquid material and the water in the cooling tank. The evaporation of the water carries away the heat from the material, thus achieving cooling. However, this process has many drawbacks, the most prominent being the direct loss of heat into the air. During the cooling process, a large amount of heat energy is not effectively recovered and reused, but is directly released into the environment. This not only represents a significant waste of energy but also increases the production costs for enterprises.

[0004] The high-temperature liquid materials generated during the production process reach temperatures as high as 135°C, resulting in significant heat loss when cooled using traditional cooling tanks. Simultaneously, other production processes and auxiliary facilities, such as the insulation of raw material storage tank areas and the preheating of certain chemical reactions, require substantial energy consumption to maintain suitable temperatures. This imbalance between energy supply and demand, and the resulting inefficient use of energy, is a serious problem. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide a device that can efficiently recover the heat energy released during the cooling process of high-temperature liquid materials and reduce energy consumption, which is of great significance to the sustainable development of the chemical industry. The emergence of high-efficiency heat recovery devices is precisely to solve these long-standing technical problems and promote the chemical industry towards a greener and more efficient direction.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A heat energy recovery device for high-temperature liquid materials includes a cooling water tank. The cooling water tank is equipped with a high-temperature medium inlet valve for the inflow of high-temperature medium and a low-temperature medium outlet valve for the outflow of low-temperature medium. A cooling coil is installed inside the cooling water tank. The high-temperature medium inlet valve is connected to the inlet end of the cooling coil, and the outlet end of the cooling coil is connected to the low-temperature medium outlet valve. The cooling water tank is also equipped with a replenishment valve for replenishing industrial water. The cooling water tank is equipped with an oil outlet pipe and a return water pipe. A heating coil connecting the outlet pipe and the return water pipe is connected to the tank area. The high-temperature water formed in the cooling water tank due to the rise of high-temperature liquid materials is connected to the heating coil through the outlet pipe. After the high-temperature water is cooled down, it re-enters the cooling water tank through the return water pipe.

[0007] A further preferred embodiment of this utility model is as follows: a hot water circulation pump is installed on the water outlet pipe, a hot water pump inlet manual valve is installed at the inlet end of the hot water circulation pump, and a hot water pump outlet manual valve is installed at the outlet end.

[0008] A further preferred embodiment of this utility model is that a first temperature gauge and a first pressure gauge are provided on the water outlet pipe.

[0009] A further preferred embodiment of this utility model is: a float valve is provided at the replenishment valve for industrial sailors.

[0010] A further preferred embodiment of this utility model is that the cooling coil is a combination of multiple S-shaped coils, which are installed inside the cooling water tank.

[0011] A further preferred embodiment of this utility model is: a residual oil sampler is provided on the cooling water tank, and the residual oil sampler is located on the pipeline between the low temperature medium outlet valve and the outlet end of the cooling coil.

[0012] A further preferred embodiment of this utility model is as follows: a second temperature gauge and a second pressure gauge are sequentially installed on the pipeline before the high-temperature medium enters the valve, and a third temperature gauge and a third pressure gauge are sequentially installed on the pipeline before the low-temperature medium exits the valve.

[0013] A further preferred embodiment of this utility model is that a sixth pressure gauge is provided at the bottom of the cooling water tank.

[0014] A further preferred embodiment of this utility model is that the return water pipe is equipped with a fourth temperature gauge and a fourth pressure gauge.

[0015] This invention introduces high-temperature liquid materials into cooling coils within a cooling water tank, raising the temperature of the water. The resulting high-temperature water is then transported through an outlet pipe to a heating coil in the tank area for further heating. After cooling, the water returns to the cooling water tank via a return pipe. This achieves the recovery and recycling of heat energy from the high-temperature liquid materials, avoiding the energy waste caused by direct heat loss into the air in traditional cooling methods. This effectively reduces energy consumption and production costs. The high-temperature liquid materials flow within the cooling coils, exchanging heat with the water in the tank, thereby lowering the material's temperature to meet the requirements of subsequent storage or processing. This achieves both material cooling and heat energy recovery. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, a heat recovery device for high-temperature liquid materials includes a cooling water tank 1. The cooling water tank 1 is equipped with a high-temperature medium inlet valve 2 for the inflow of high-temperature medium and a low-temperature medium outlet valve 3 for the outflow of low-temperature medium. A cooling coil 4 is installed inside the cooling water tank 1. The high-temperature medium inlet valve 2 is connected to the inlet end of the cooling coil 4, and the outlet end of the cooling coil 4 is connected to the low-temperature medium outlet valve 3. The cooling water tank 1 is also equipped with a replenishment valve 5 for replenishing industrial water. The cooling water tank 1 is provided with an outlet pipe 6 and a return pipe 7. A heating coil 8 connecting the outlet pipe 6 and the return pipe 7 is connected to the tank area. The high-temperature water formed in the cooling water tank 1 due to the rise of the high-temperature liquid material is connected to the heating coil 8 through the outlet pipe 6. After the high-temperature water is cooled down, it re-enters the cooling water tank 1 through the return pipe 7. By introducing high-temperature liquid material into the cooling coil 4 inside the cooling water tank 1, the water in the tank is heated. The resulting high-temperature water is then transported through the outlet pipe 6 to the heating coil 8 in the tank area for heating. After cooling, it returns to the cooling water tank 1 through the return water pipe 7. This achieves the recovery and recycling of heat energy from the high-temperature liquid material, avoiding the energy waste caused by the direct loss of heat into the air in traditional cooling methods, and effectively reducing energy consumption and production costs. The high-temperature liquid material flows in the cooling coil 4, exchanging heat with the water in the tank, thereby lowering the material's temperature to meet the requirements of subsequent storage or processing.

[0019] A hot water circulation pump 9 is installed on the outlet pipe 6. The inlet end of the hot water circulation pump 9 is equipped with a hot water pump inlet manual valve 10, and the outlet end is equipped with a hot water pump outlet manual valve 11. The hot water circulation pump 9 provides power for the circulation of high-temperature water in the cooling water tank 1 between the outlet pipe 6 and the return pipe 7, ensuring that the high-temperature water can be continuously delivered to the heating coil 8 in the tank area for heat exchange, thus guaranteeing the continuity and stability of heat energy recovery and utilization. The hot water pump inlet manual valve 10 and the hot water pump outlet manual valve 11 can control the inlet and outlet flow rates of the hot water circulation pump 9, facilitating adjustments and maintenance by operators according to actual production conditions, and improving the operational flexibility and reliability of the device.

[0020] A first temperature gauge 12 and a first pressure gauge 13 are installed on the water outlet pipe 6. These gauges can monitor the temperature and pressure parameters of the high-temperature water during the transportation process in real time. By monitoring these parameters, operators can promptly understand the operating status of the hot water circulation system, determine if there are any abnormalities, such as excessively high temperature or abnormal pressure, and take corresponding measures to adjust and ensure the safe and stable operation of the device.

[0021] A float valve 14 is installed at the industrial water supply valve 5. This float valve 14 automatically controls the replenishment of industrial water according to the water level in the cooling water tank 1. When the water level in the tank drops, the float valve 14 opens to replenish industrial water; when the water level reaches the set height, the float valve 14 closes to stop replenishing water. This automatic control method ensures that the water level in the cooling water tank 1 remains within a suitable range, guaranteeing the normal operation of the heat exchange process, while avoiding the inconvenience of frequent manual operation and improving the automation level of the device. The cooling coil 4 consists of multiple sets of S-shaped coils arranged inside the cooling water tank 1. The use of multiple sets of S-shaped coils in the cooling coil 4 significantly increases the contact area between the high-temperature liquid material and the water in the tank, improving heat exchange efficiency. Compared to ordinary straight-tube coils, S-shaped coils allow for a longer flow path for high-temperature liquid materials within the coil, resulting in more thorough heat exchange with water. This more effectively reduces the material temperature and also heats the water in the tank more quickly, improving the efficiency of heat recovery.

[0022] A residual oil sampler 15 is installed on the cooling water tank 1, located on the pipeline between the low-temperature medium outlet valve 3 and the outlet end of the cooling coil 4. This sampling device allows for convenient sampling and testing of the residual oil after cooling. Analysis of the residual oil sample allows operators to understand the quality changes of the residual oil, determine whether the cooling process has affected its properties, provide a basis for subsequent production process adjustments, and ensure product quality stability.

[0023] A second thermometer 16 and a second pressure gauge 17 are sequentially installed on the pipeline before the high-temperature medium inlet valve 2, and a third thermometer 18 and a third pressure gauge 19 are sequentially installed on the pipeline before the low-temperature medium outlet valve 3. These gauges allow for real-time monitoring of the temperature and pressure of the high-temperature liquid material entering the cooling coil 4 and the low-temperature medium exiting the cooling coil 4. By comparing and analyzing these parameters, operators can gain a comprehensive understanding of the heat exchange process's effectiveness, assess the device's operating efficiency, promptly identify potential problems, and make adjustments to ensure the device is always operating at its optimal state.

[0024] A sixth pressure gauge 20 is installed at the bottom of the cooling water tank 1. This sixth pressure gauge 20 can monitor the pressure inside the tank in real time. Since the water in the cooling water tank 1 will experience pressure changes after absorbing heat from the high-temperature liquid material, monitoring the pressure at the bottom of the tank allows for timely detection of any abnormal pressure conditions. For example, excessively high pressure may lead to tank damage or leakage, posing a safety hazard. Appropriate measures can then be taken to address these issues and ensure the safe operation of the device.

[0025] The return water pipeline is equipped with a fourth temperature gauge 21 and a fourth pressure gauge 22. These gauges can accurately monitor the temperature and pressure of the hot water entering and exiting the heating coil 8 in the tank area. By monitoring and analyzing these parameters, operators can accurately grasp the heating effect of the tank area, adjust the flow rate and temperature of the hot water according to actual needs, achieve precise control of the heating process in the tank area, and improve the efficiency of heat energy utilization and the stability of the heating effect.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas.
