Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery, and more specifically, to a novel vacuum jacketed heat exchanger device with waste heat recovery. Background Technology

[0002] In modern industrial production, heat exchangers, as an important heat exchange device, are widely used in many fields such as chemical, petroleum, pharmaceutical, and food industries. Their function is to achieve processes such as heating, cooling, condensation, and evaporation through the transfer of heat between fluids at different temperatures, so as to meet the temperature control requirements of the production process. However, traditional heat exchangers have many problems in operation, especially in terms of energy utilization and environmental protection, where they face severe challenges.

[0003] Waste heat refers to the sensible and latent heat that has not been rationally utilized in the original design of energy-consuming equipment in industrial enterprises that has been put into operation due to limitations such as historical, technological, and conceptual factors. It includes waste heat from high-temperature exhaust gas, waste heat from cooling media, waste steam and wastewater, waste heat from high-temperature products and slag, waste heat from chemical reactions, and waste heat from combustible exhaust gas, waste liquid, and waste materials. According to surveys, the total waste heat resources of various industries account for approximately 17% to 67% of their total fuel consumption, and the recoverable waste heat resources account for approximately 60% of the total waste heat resources.

[0004] In the operation of traditional heat exchangers, steam, as a commonly used heat source, usually forms condensate after heat exchange. This condensate often contains a large amount of waste heat, but due to the lack of effective recovery and utilization methods, this waste heat is usually directly discharged into the environment, resulting in a huge waste of energy. According to statistics, in some large-scale industrial production, the waste heat carried by steam condensate accounts for a considerable proportion of the total energy consumption. If this waste heat can be effectively recovered and utilized, it will bring significant economic benefits to enterprises and also help alleviate the energy shortage situation.

[0005] Therefore, this application provides a novel vacuum jacketed heat exchanger device with waste heat recovery to solve the problems mentioned in the background art. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a new type of vacuum jacketed heat exchanger device with waste heat recovery, which can improve the comprehensive utilization rate of energy, significantly reduce energy consumption, achieve the effect of energy saving and emission reduction, and meet the current industrial needs of green environmental protection and sustainable development.

[0007] To solve the above problems, this utility model adopts the following technical solution: A novel vacuum jacketed heat exchanger device with waste heat recovery, comprising a vacuum jacketed heat exchanger, a heat exchange jacket at the outer end of the vacuum jacketed heat exchanger, a steam pipe embedded in the heat exchange jacket, a discharge port and a drain port at the bottom end of the vacuum jacketed heat exchanger, the drain port being located to the right of the discharge port, a steam condensate outlet fixedly connected to the end of the steam pipe, a steam condensate pipe fixedly connected to the outer end of the steam condensate outlet, an ultra-high temperature heat pump installed at the outer end of the steam condensate pipe, and supports fixedly connected to the bottom ends of both the vacuum jacketed heat exchanger and the ultra-high temperature heat pump. A shock absorber is installed at the bottom of the support frame, and a hoisting platform is installed at the bottom of the shock absorber. Two symmetrical hoisting ports are installed at the top of the hoisting platform. High-temperature hot water pipes and heat pump return water pipes are arranged vertically between the ultra-high temperature heat pump and the vacuum jacketed heat exchanger. Hot water inlet and warm water outlet are installed vertically at the right end of the vacuum jacketed heat exchanger. The hot water inlet is connected to the high-temperature hot water pipe, and the warm water outlet is connected to the heat pump return water pipe. This can improve the comprehensive utilization rate of energy, significantly reduce energy consumption, achieve the effect of energy conservation and emission reduction, and meet the current industrial needs of green environmental protection and sustainable development.

[0008] As a further improvement of this utility model, valves, hot water pumps, and temperature sensors are installed on the steam condensate pipe, the high-temperature hot water pipe, and the heat pump return pipe.

[0009] As a further improvement of this utility model, pressure sensors are installed on both the high-temperature hot water pipe and the heat pump return water pipe.

[0010] As a further embodiment of this utility model: the upper end of the vacuum jacketed heat exchanger is equipped with a material inlet, and a flange connection hole is drilled at the outer end of the material inlet.

[0011] As a further improvement of this utility model: a vacuum port and a liquid level sensor are installed at the left end of the heat exchange jacket, and the vacuum port is located above the liquid level sensor.

[0012] As a further improvement of this utility model, a power distribution cabinet is provided on one side of the device.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. This device sends the condensate from the heat exchange jacket into an ultra-high temperature heat pump to recover waste heat through a steam condensate pipe and a steam condensate outlet. The ultra-high temperature heat pump absorbs the waste heat in the condensate and transfers this heat to the circulating water, achieving efficient recovery and utilization of waste heat. The hot water after absorbing waste heat is sent into the heat exchange jacket through a high-temperature hot water pipe to exchange heat with the materials. The low-temperature water in the jacket then flows back to the ultra-high temperature heat pump through the heat pump return water pipe for reheating, forming a hot water recycling process. This process greatly improves the comprehensive utilization rate of energy, significantly reduces energy consumption, achieves the effect of energy saving and emission reduction, and meets the current industrial needs of green environmental protection and sustainable development.

[0015] 2. This device is equipped with temperature and pressure sensors on the steam condensate pipe, high-temperature hot water pipe, and heat pump return water pipe. These sensors can monitor the temperature and pressure of the fluid in the pipes in real time and transmit the data to the control system. Based on the monitoring data, the control system adjusts the flow rate of the fluid in the pipes through valves and controls the circulation speed of the hot water through the hot water pump. This achieves precise control of the device's operation, ensuring that the system operates under safe and stable conditions. It effectively avoids equipment failures and production accidents caused by abnormal temperature or pressure, thereby improving production efficiency and product quality.

[0016] 3. This device uses a support frame to support the weight of the vacuum jacketed heat exchanger and the ultra-high temperature heat pump. The shock absorber reduces vibration during operation, ensuring stable operation. The lifting platform and lifting port facilitate hoisting and installation, reducing installation difficulty and cost. Additionally, a flange connection hole is drilled at the outer end of the material inlet for easy connection and sealing of the material inlet pipe. A vacuum port and liquid level sensor are installed on the left end of the heat exchange jacket, facilitating the adjustment and monitoring of the environment within the jacket. These designs make installation, maintenance, and repair more convenient, improving the equipment's service life and reliability. Attached Figure Description
