Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery equipment, specifically an electro-thermal chemical energy storage waste heat recovery heating device. Background Technology

[0002] In the field of energy utilization, electro-thermal chemical energy storage systems, as a highly efficient and promising energy storage and conversion technology, are gradually attracting widespread attention. During operation, these systems generate a significant amount of waste heat due to chemical reactions, current conduction, and energy losses within the equipment itself. This waste heat contains considerable energy; if it is not effectively recovered and utilized, it will not only lead to enormous energy waste, reduce the overall energy efficiency of the system, and increase energy costs, but may also have adverse effects on the environment in which the system operates, such as causing localized temperature increases, thermal pollution, and affecting the lifespan of the equipment and the surrounding ecological balance.

[0003] Currently, in terms of waste heat recovery technology, traditional methods mostly use a single heat exchanger to achieve heat transfer. This traditional waste heat recovery method has obvious limitations. The heat exchange efficiency of a single heat exchanger is relatively low, and the heat exchange capacity is limited. After heat exchange, the exhaust gas still has a high temperature, which means that a considerable amount of waste heat is still discharged into the environment with the exhaust gas, resulting in secondary waste of resources. Utility Model Content

[0004] The purpose of this invention is to provide an electro-thermal chemical energy storage waste heat recovery heating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electro-thermal chemical energy storage waste heat recovery heating device, comprising a primary heat exchange box and a secondary heat exchange box; an air inlet pipe is fixedly connected to one side of the primary heat exchange box, and a plurality of first baffles and a plurality of second baffles are fixedly connected inside the primary heat exchange box, with the plurality of first baffles and the plurality of second baffles spaced apart, and each of the plurality of first baffles having an opening at its bottom end and the plurality of second baffles having an adjustment component at its bottom end; a first pipe is provided inside the primary heat exchange box, with both ends of the first pipe extending out of the primary heat exchange box; a secondary heat exchange box is fixedly connected to the bottom end of the primary heat exchange box via a connector, and a connecting pipe is fixedly connected between the secondary heat exchange box and the primary heat exchange box, with an adjustment valve fixedly connected to the outside of the connecting pipe; an exhaust pipe is fixedly connected to one side of the secondary heat exchange box, and a second pipe is provided inside the secondary heat exchange box, with both ends of the second pipe extending out of the secondary heat exchange box, and the second pipe being arranged in a spiral configuration.

[0006] Preferably, the first pipe is arranged in a spiral pattern inside the primary heat exchanger box, and the first pipe passes through several first baffles and several second baffles.

[0007] Preferably, the air intake pipe is connected to the electro-thermal chemical energy storage system via a connecting pipe.

[0008] Preferably, a cover plate is fitted onto the upper end of the primary heat exchange box, and a sealing gasket is fixedly connected to the bottom end of the cover plate. The bottom end of the sealing gasket is tightly fitted with the upper ends of a plurality of first baffles and a plurality of second baffles.

[0009] Preferably, each of the adjustment components includes a fixed block and a stop block. The fixed block is fixed to the outside of the first baffle, and the stop block is movably sleeved with the fixed block. The stop block is located directly above the bottom opening of the first baffle. An installation block is fixedly connected to one side of the upper end of the stop block, and a bolt is threaded onto the installation block. The bottom end of the bolt is rotatably connected to the upper end of the fixed block.

[0010] Compared with existing technologies, by extracting heat from waste heat gas in stages, every bit of heat can be utilized to the maximum extent. This efficient heat exchange mechanism greatly improves the waste heat recovery efficiency. Compared with traditional single heat exchangers, it can recover much more waste heat energy. Moreover, according to different needs in actual production, life or experiments, this equipment can flexibly provide media of different temperatures, truly realizing on-demand energy allocation and efficient utilization.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: An electro-thermal chemical energy storage waste heat recovery heating device includes a primary heat exchange box 1 and a secondary heat exchange box 2. An air inlet pipe 3 is fixedly connected to one side of the primary heat exchange box 1. Several first baffles 11 and several second baffles 12 are fixedly connected inside the primary heat exchange box 1, spaced apart. Openings 13 are provided at the bottom of the first baffles 11 and the top of the second baffles 12. A first pipe 5 is provided inside the primary heat exchange box 1, with both ends of the first pipe 5 extending out of the primary heat exchange box 1. The bottom of the primary heat exchange box 1 is connected to... A secondary heat exchange box 2 is fixedly connected via a connector. A through pipe 7 is fixedly connected between the secondary heat exchange box 2 and the primary heat exchange box 1. A regulating valve 8 is fixedly connected to the outside of the through pipe 7. An exhaust pipe 4 is fixedly connected to one side of the secondary heat exchange box 2. A second pipe 6 is provided inside the secondary heat exchange box 2. Both ends of the second pipe 6 extend out of the secondary heat exchange box 2. The second pipe is arranged in a spiral state. Through the dual-stage design of the high-temperature chamber of the primary heat exchange box 1 and the low-temperature chamber of the secondary heat exchange box 2, gradient temperature recovery of the hot gas is achieved, resulting in higher heat exchange efficiency and the recovery of more heat, thus saving resources.

[0019] The first pipe 5 is coiled inside the first-stage heat exchange box 1. The first pipe 5 passes through several first baffles 11 and several second baffles 12, which increases the contact area and contact time between the first pipe 5 and the waste heat gas, so that heat can be transferred more fully from the waste heat gas to the medium inside the first pipe 5.

[0020] The air inlet pipe 3 is connected to the electro-thermal chemical energy storage system through a connecting pipe. The hot air generated during the operation of the electro-thermal chemical energy storage system is transported to the first-stage heat exchange box 1 through the air inlet pipe 3.

[0021] The upper end of the primary heat exchange box 1 is fitted with a cover plate 10, and the bottom end of the cover plate 10 is fixedly connected with a sealing gasket 14. The bottom end of the sealing gasket 14 is tightly fitted with the upper ends of several first baffles 11 and several second baffles 12. The internal components can be maintained by opening the cover plate 10 later.

[0022] During use, a large amount of waste heat gas is generated during the operation of the electro-thermal chemical energy storage system. The waste heat gas continuously flows into the primary heat exchanger 1 through the inlet pipe 3. After entering the primary heat exchanger 1, the waste heat gas flows along a preset path, passing through the carefully designed openings 13 on the first baffle 11 and the second baffle 12. During this flow process, the waste heat gas and the first pipe 5, which swirls between the first baffle 11 and the second baffle 12, have comprehensive and deep contact. The heat is rapidly transferred from the high-temperature waste heat gas to the medium in the first pipe 5, as if drawn by an invisible hand. Due to the sufficient heat exchange, the temperature of the medium in the first pipe 5 is significantly increased. Its high-temperature characteristics enable it to play an important role in many fields. For example, in chemical experiments, it can serve as a stable heat source, providing suitable temperature conditions for experimental reactions and facilitating the smooth progress of experiments. After efficient heat exchange in the first pipe 5, although the temperature of the waste heat gas is reduced, it still contains considerable heat. At this time, the waste heat gas smoothly enters the secondary heat exchanger 2 through the connecting pipe 7 between the primary heat exchanger 1 and the secondary heat exchanger 2. Inside the secondary heat exchanger 2, the waste heat gas undergoes a new round of heat exchange with the medium in the spirally arranged second pipe 6. Compared to the medium in the first pipe 5, the medium in the second pipe 6 has a relatively lower temperature. After this heat exchange, the medium in the second pipe 6 absorbs some of the heat from the waste heat gas, raising its temperature to form hot water. This hot water has a wide range of uses, such as for routine cleaning of equipment. It can effectively remove dirt and impurities from the equipment surface and fully utilize waste heat, achieving secondary energy utilization.

[0023] In embodiment two, based on the technical solution of embodiment one, several adjustment components 9 are further provided. These adjustment components 9 are respectively disposed on one side of the bottom end of several first baffles 11. Each adjustment component 9 includes a fixing block 91 and a stop block 92. The fixing block 91 is fixed to the outside of the first baffle 11, and the stop block 92 is movably sleeved with the fixing block 91. The stop block 92 is located directly above the bottom opening of the first baffle 11. An installation block 93 is fixedly connected to one side of the upper end of the stop block 92. A bolt 94 is threadedly connected to the installation block 93, and the bottom end of the bolt 94 is rotatably connected to the upper end of the fixing block 91. By adjusting the position of the stop block 92, the size of the bottom opening of the first baffle 11 can be changed, thereby adjusting the flow rate and residence time of the waste heat gas in the first-stage heat exchange box 1. In practical applications, the adjustment components 9 can be flexibly adjusted according to factors such as the temperature and flow rate of the waste heat gas and the heat to be recovered, optimizing the heat exchange process and ensuring efficient waste heat recovery under different operating conditions, further enhancing the heat exchange capacity.
