Description

Technical Field

[0001] This utility model relates to the field of heat loss circulating evaporation technology, and more specifically, to a forced circulating evaporation device for heat loss control. Background Technology

[0002] In many industrial production fields, such as chemical, pharmaceutical, and food processing, evaporation equipment is one of the important unit operation devices. However, traditional evaporation equipment suffers from serious heat loss problems. On the one hand, the insulation performance of the evaporator is insufficient, and heat is easily lost to the surrounding environment through the walls of the equipment. For example, some old-fashioned evaporators are only wrapped with simple insulation materials. Over time and with the operation of the equipment, the insulation materials may age or break down, leading to an increase in thermal conductivity and exacerbating heat loss. On the other hand, during the evaporation process, secondary steam carries a large amount of latent heat and is directly discharged into the atmosphere without being effectively recovered and utilized. This heat loss accounts for a large proportion of the energy consumption of the entire evaporation system.

[0003] Therefore, there is an urgent need for a forced circulation evaporation device for heat loss control to improve the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a forced circulation evaporation device for heat loss control, so as to solve the problems mentioned in the background art.

[0007] As a further improvement to this technical solution, a fixing frame is fixedly connected to the surface of the evaporator, and the fixing frame is fixedly connected to the upper surface of the platform. A bracket is fixedly connected inside the second heat-insulating shell, and the bracket is fixedly connected to the outer surface of the evaporator.

Key components such as the evaporator and piping are meticulously insulated, utilizing a multi-layered composite insulation structure including high-efficiency insulation materials and a well-sealed protective layer. This effectively reduces heat conduction and radiation from the equipment surface to the surrounding environment, significantly improving energy efficiency and lowering energy costs. The equipped secondary steam latent heat recovery system efficiently recovers the latent heat from the secondary steam generated by the evaporator. The steam is condensed into liquid by the condenser, and the recovered heat is reused to preheat the feed solution or other processes requiring heating, further reducing overall system heat loss and enabling more efficient energy utilization.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 As shown, this embodiment provides a forced circulation evaporation device for heat loss control, including a support assembly 1. The support assembly 1 includes a platform 10, and a circulation evaporation assembly 2 is fixedly connected to the platform 10. The circulation evaporation assembly 2 includes a preheating tank 20, and the preheating tank includes a heating barrel 204. An insulation shell 203 is fixedly connected to the outer surface of the heating barrel 204. An insulation cavity 205 is provided between the insulation shell 203 and the heating barrel 204, and the insulation cavity 205 is filled with insulation material. A liquid delivery pipe 208 is fixedly connected to the upper surface of the heating barrel 204, and the other end of the liquid delivery pipe 208 is fixedly connected to an evaporation device. Evaporator 21 is used for the evaporation of liquid. An insulating outer shell 211 is fixedly connected to the surface of evaporator 21. An insulating cavity 210 is provided between the insulating outer shell 211 and evaporator 21. Insulating cotton 212 is fixedly connected to the outer surface of the insulating outer shell. An expansion joint 214 is fixedly connected to the surface of the outer shell 214, which is connected to the insulating cavity. A steam pipe 231 is fixedly connected to the upper surface of evaporator 21. A condenser 23 is fixedly connected to the other end of the steam pipe 231. A circulation pipe 221 is fixedly connected to the surface of evaporator 21. A heat exchanger 22 is fixedly connected to the other end of the circulation pipe 221.

[0021] The above working principle is as follows: First, the raw material liquid enters the heating tank 204 of the preheating tank 20 through an external pipe. The insulation shell 203 outside the heating tank 204 and the insulation material filled inside effectively reduce heat loss and preheat the liquid. Then, the preheated liquid flows into the evaporator 21 through the liquid delivery pipe 208. The insulation shell 211 on the surface of the evaporator 21, the insulation cotton 212, the insulation cavity 210, and the compensation port 214 further enhance the insulation effect and reduce heat loss. In the evaporator 21, the liquid evaporates due to heat, and the generated steam enters the condenser 23 through the steam pipe 231 for condensation and recovery. Meanwhile, the unevaporated liquid in the evaporator 21 enters the heat exchange tank 22 through the circulation pipe 221. After exchanging heat with other media, the temperature changes, and the liquid is then circulated back into the evaporator 21 to continue participating in the evaporation process. This cycle repeats continuously. By using efficient heat preservation measures to reduce heat loss and utilizing the circulation mechanism to continuously evaporate and concentrate the liquid, heat loss can be effectively controlled and the evaporation operation can be carried out continuously and stably, thereby improving energy utilization efficiency and meeting the evaporation needs in the production process.

[0022] To preheat the feed material, in this embodiment, a support leg 11 is fixedly connected to the lower surface of the platform 10, and an inlet pipe 202 is fixedly connected to the lower surface of the heating tank 204. A feed pump 201 is fixedly connected to one end of the inlet pipe 202, and a feed pipe 200 is fixedly connected to the other end of the feed pump 201. A heating rod 206 is fixedly connected inside the heating tank 204, and a heat source pipe 207 is fixedly connected to the surface of the heating tank 204. The other end of the heat source pipe 207 is fixedly connected to the condenser tank 23. When the equipment is started, the feed pump 201 begins to work, drawing in the raw material through the feed pipe 200. The raw material then enters the heating tank 204 through the inlet pipe 202. The heating rod 206 inside the heating tank 204 generates heat when energized, directly heating the raw material inside the tank. Simultaneously, a heat source with a certain amount of heat from the condenser tank 23 is introduced around the heating tank 204 through the heat source pipe 207, working together with the heating rod 206 to preheat the raw material to a certain temperature before it enters the evaporator tank 21. This preheating method not only utilizes the waste heat generated by the equipment itself, improving energy efficiency, but also enables the raw materials to reach the required evaporation temperature more quickly after entering the evaporator 21, accelerating the evaporation process and reducing the energy consumed by relying solely on external heating in the evaporator 21. Thus, the rational distribution and efficient utilization of heat are achieved at the beginning of the entire evaporation process, laying the foundation for subsequent stable evaporation operations.

[0023] To minimize heat loss, in this embodiment, a fixing frame 215 is fixedly connected to the surface of the evaporator 21, and the fixing frame 215 is fixedly connected to the upper surface of the platform 10. A support 213 is fixedly connected inside the insulation shell 211, and the support 213 is fixedly connected to the outer surface of the evaporator 21. A discharge pipe 216 is fixedly connected to the surface of the evaporator 21, and the discharge pipe 216 is used to connect to subsequent processing equipment. The support 213 inside the insulation shell 211 further strengthens the support and fixation of the evaporator 21, while also reducing the direct contact area between the evaporator 21 and the external environment. The insulation shell 211 and its internal insulation material form an effective heat insulation barrier, greatly reducing the conduction of heat from the inside of the evaporator 21 to the external environment. When the liquid in the evaporator 21 evaporates, the generated heat is retained within the tank as much as possible, reducing energy waste caused by heat loss. When the discharge pipe 216 of the evaporator 21 is connected to the subsequent processing equipment, corresponding heat preservation measures are also taken to ensure that heat is not lost in large quantities during the discharge process, thereby ensuring the thermal efficiency of the entire evaporation process. This allows the equipment to maintain efficient evaporation operation with low energy consumption during operation, reducing production costs and improving economic benefits.

[0024] To fully utilize heat, in this embodiment, a hot liquid pipe 220 is fixedly connected to the upper surface of the heat exchange tank 22, and the other end of the hot liquid pipe 220 is fixedly connected to the evaporator 21. A forced circulation pump 222 is fixedly connected to one end of the circulation pipe 221, which pumps the liquid in the evaporator 21 into the heat exchange tank 22. A condensate tank 230 is fixedly connected to the lower surface of the condenser 23. The hot liquid pipe 220 in the heat exchange tank 22 transports the heated liquid in the tank back to the evaporator 21 after heat exchange, providing additional heat to the liquid in the evaporator 21 to replenish the heat lost during evaporation, ensuring that the liquid in the evaporator 21 can be continuously maintained in a temperature range conducive to evaporation, further improving evaporation efficiency. The forced circulation pump 222 at one end of the circulation pipe 221 powerfully drives the unevaporated liquid in the evaporator 21 into the heat exchange tank 22. In the heat exchange tank 22, the liquid undergoes sufficient heat exchange with other media at suitable temperatures, absorbing heat before circulating back to the evaporator 21 to continue evaporation. The condensate tank 230 below the condensate tank 23 collects the condensate generated during the condensation process, preventing the condensate from being discharged indiscriminately and causing heat waste.

[0025] In this embodiment, a forced circulation evaporation device for heat loss control is used in the following way: First, after the device is started, the feed pump 201 begins operation, drawing in the raw material through the feed pipe 200. The raw material then enters the heating tank 204 through the inlet pipe 202. The heating rod 206 inside the heating tank 204 generates heat after being energized, directly heating the raw material inside the tank. Simultaneously, a heat source with a certain amount of heat in the condenser 23 is introduced around the heating tank 204 through the heat source pipe 207, working together with the heating rod 206 to preheat the raw material to a certain temperature before it enters the evaporator 21. The insulation shell 203 outside the heating tank 204 and the insulation material inside effectively reduce heat loss, providing initial preheating of the liquid. Afterward, the preheated liquid flows into the evaporator 21 through the liquid delivery pipe 208. The support 213 inside the insulation shell 211 further strengthens the support and fixation of the evaporator 21, while also reducing the direct contact area between the evaporator 21 and the external environment. The insulating outer shell 211 and its internal insulation material form an effective heat insulation barrier, greatly reducing the conduction of heat from the inside of the evaporator 21 to the external environment. When the liquid in the evaporator 21 evaporates, the generated heat is retained in the tank as much as possible, reducing energy waste caused by heat loss. When the discharge pipe 216 of the evaporator 21 is connected to the subsequent processing equipment, corresponding insulation measures are also taken to ensure that heat is not lost in large quantities during the discharge process, thereby ensuring the thermal efficiency of the entire evaporation process. This allows the equipment to maintain efficient evaporation operation with low energy consumption during operation, reducing production costs and improving economic benefits. The unevaporated liquid in the evaporator 21 enters the heat exchange tank 22 through the circulation pipe 221. After exchanging heat with other media, the temperature changes, and it is then circulated back to the evaporator 21 to continue participating in the evaporation process. The forced circulation pump 222 at one end of the circulation pipe 221 strongly drives the unevaporated liquid in the evaporator 21 into the heat exchange tank 22. In the heat exchange tank 22, the liquid undergoes sufficient heat exchange with other media with suitable temperatures, absorbs heat, and is then circulated back to the evaporator 21 to continue evaporation. The condensate tank 230 below the condenser 23 collects the condensate generated during the condensation process, preventing the condensate from being discharged indiscriminately and causing heat waste. This cycle repeats continuously, reducing heat loss through efficient insulation measures and using the circulation mechanism to continuously evaporate and concentrate the liquid, thereby achieving effective control of heat loss and continuous and stable evaporation operation, improving energy efficiency and meeting the evaporation needs in the production process.
