Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange reactors, and particularly relates to a parallel double-layer heat exchange plate reactor. Background Art

[0002] The parallel double-layer heat exchange plate reactor is a special heat exchange device, and its design combines the concepts of parallel connection and double-layer heat exchange to improve heat exchange efficiency and flexibility. Its working principle is based on the heat exchange mechanism of a plate heat exchanger. The cold and hot fluids flow through both sides of the heat exchange plate respectively, and the temperature exchange of the fluids is achieved through the heat transfer between the plates. In the parallel double-layer heat exchange plate reactor, due to the adoption of a double-layer structure and a parallel configuration, the cold and hot fluids can flow in multiple channels simultaneously, thereby improving the heat exchange efficiency and fluid processing capacity.

[0003] In the existing parallel double-layer heat exchange plate reactor, the reaction gas and the heat exchange liquid mostly exchange heat through the heat exchange plate. However, the reaction gas and the heat exchange liquid are both centrally transported and heat exchanged. Since the volume inside the reactor is limited, the size of the heat exchange plate will be restricted to a certain extent. The centrally transported reaction gas and heat exchange liquid will be restricted by the size of the heat exchange plate, resulting in limited heat exchange effect. It often needs to be refluxed for secondary heat exchange, which affects the subsequent reaction efficiency of the reaction gas. Therefore, there are still certain deficiencies in the existing parallel double-layer heat exchange plate reactor.

[0004] In summary, it is very necessary to invent a parallel double-layer heat exchange plate reactor. Content of the Utility Model

Specific embodiments

[0024] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0025] Embodiment 1:

[0026] Refer to the attached Figures 1-5, a parallel double-layer heat exchange plate reactor provided by the utility model includes a reaction tank 100. A partition is fixed at the center of the inner wall of the reaction tank 100. An exchanger mechanism 200 is arranged below the partition inside the reaction tank 100. The exchanger mechanism 200 is an exchanger housing 201. The arranged exchanger housing 201 and the first heat exchange partition 202 are of a two-piece structure. During use, personnel can splice them together to form a sealed box. A first heat exchange partition 202 is integrally fixed to the inner walls of the opposite sides of the two exchanger housings 201. A first positioning pin 203 is fixed at the abutting end of any one of the first heat exchange partitions 202. First sealing slots are opened at the corresponding positions of the abutting ends of the other first heat exchange partition 202 and the first positioning pin 203. The outer walls of the first positioning pins 203 are inserted into the inner walls of the first sealing slots. When personnel install the exchanger housing 201, the arranged first heat exchange partition 202 can be spliced together through the first positioning pins 203 and the opened first sealing slots. At this time, the arranged first heat exchange partition 202 can divide the space inside the exchanger housing 201, thereby being able to separate the reaction gas and the heat exchange liquid. Liquid separation can avoid the concentration of the reaction gas and the heat exchange liquid together, thus improving the heat exchange effect. A liquid exchange inlet pipe 210 for inputting the heat exchange liquid is fixed at the bottom of the front end of the outer wall of the front-end exchanger housing 201. A liquid exchange outlet pipe 230 for discharging the heat exchange liquid is fixed at the top of the front end of the outer wall of the front-end exchanger housing 201. The outer walls of the front-end exchanger housing 201 are communicated with the liquid exchange inlet pipe 210 and the liquid exchange outlet pipe 230 through the opened first liquid discharge ports. The arranged liquid exchange inlet pipe 210, the first air inlet pipe 220, the liquid exchange outlet pipe 230, and the connecting elbow 240 can be of a segmented structure, which can facilitate the subsequent removal of the exchanger mechanism 200 and the reactor mechanism 300, but sealing work needs to be done well to avoid air leakage and liquid leakage. A first air inlet pipe 220 for conveying materials is fixed at the bottom of the rear end of the outer wall of the rear-end exchanger housing 201. The bottom end of the connecting elbow 240 is communicated with the upper side of the outer surface of the rear end of the rear-end exchanger housing 201. The outer walls of the rear-end exchanger housing 201 are communicated with the first air inlet pipe 220 and the connecting elbow 240 through the opened second liquid discharge ports. The first liquid discharge ports and the second liquid discharge ports are arranged in a staggered manner. Specifically, two adjacent first heat exchange partitions 202 can divide the inside of the exchanger housing 201 into an independent liquid infusion cavity space. The arranged first liquid discharge ports and the second liquid discharge ports can be communicated with the separate liquid infusion cavity spaces. The staggered arrangement can ensure that the heat exchange liquid and the reaction gas entering the first liquid discharge ports and the second liquid discharge ports can enter different liquid infusion cavity spaces, avoiding their mixing and contact, and at the same time ensuring heat exchange between the reaction gas and the heat exchange liquid. It can prevent the concentrated storage of the reaction gas and the heat exchange liquid in the liquid infusion cavity space. The material of the arranged first heat exchange partition 202 can be selected from copper or copper alloy materials;

[0027] Inside the reaction tank 100 and above the partition board, a reactor mechanism 300 is provided. The heat exchanger mechanism 200 is connected to the opposite side of the reactor mechanism 300 through a connecting elbow 240. The reactor mechanism 300 includes a reactor housing 301. Catalyst frames 302 are fixed to the inner walls of the reactor housing 301. The reactor housing 301 is provided to seal the catalyst frames 302. The catalyst frames 302 are mostly of a grid-like structure, and a catalyst for accelerating the reaction of reaction gases is stored inside. At the bottom end of the outer wall of the reactor housing 301, a second inlet pipe 310 is fixedly connected. At the top end of the outer wall of the reactor housing 301, an exhaust pipe 320 is fixedly connected. The upper end of the connecting elbow 240 is connected to the side end of the second inlet pipe 310. The heat-exchanged reaction gas can be transported into the second inlet pipe 310 through the connecting elbow 240, and then the reaction gas is transported into the reactor housing 301 by the second inlet pipe 310, so that the catalyst on the catalyst frame 302 can accelerate the reaction rate of the reaction gas, and the reacted gas can be discharged through the exhaust pipe 320.

[0028] The usage process of the present utility model is as follows: Those skilled in the art can install the device according to the above description, and then connect the corresponding reaction gas conveying equipment and heat exchange liquid conveying equipment to the corresponding pipelines;

[0029] After completion, the personnel can transport the reaction gas into the first inlet pipe 220 through the pipeline. The first inlet pipe 220 can transport the reaction gas into the heat exchanger housing 201 through the second liquid discharge port. The heat exchange liquid can be transported into the liquid change inlet pipe 210 through the pipeline. The liquid change inlet pipe 210 can enter the adjacent liquid infusion cavity space through the first liquid discharge port. In this way, the reaction gas and the heat exchange liquid can exchange heat through the first heat exchange partition board 202. The heat-exchanged reaction gas will enter the second inlet pipe 310 through the rear connecting elbow 240. The second inlet pipe 310 transports the reaction gas into the reactor housing 301, so that the catalyst on the catalyst frame 302 can accelerate the reaction rate of the reaction gas, and the reacted gas can be discharged through the exhaust pipe 320. The heat-exchanged heat exchange liquid will flow back into the device through the liquid change discharge pipe 230 for repeated use.

[0030] Embodiment Two:

[0031] Refer to the appendix Figures 6-7, compared with the first embodiment, the difference in this example is that the heat exchanger mechanism 200 is a heat exchanger housing 201. On the inner walls of the opposite sides of the two heat exchanger housings 201, a second heat exchange partition 204 is integrally fixed. A second positioning pin 205 is fixed at the abutting end of any one of the second heat exchange partitions 204. Second sealing slots are provided at the abutting ends of the other second heat exchange partition 204 and at positions corresponding to the second positioning pin 205. The outer walls of the second positioning pins 205 are inserted into the inner walls of the second sealing slots. Two adjacent first heat exchange partitions 202 can divide the interior of the heat exchanger housing 201 into an independent infusion cavity space. The material of the second heat exchange partition 204 can be selected as metallic copper, and its shape is set as a corrugated shape. Compared with the straight plate shape in the first embodiment, its heat exchange area is larger, and the heat exchange effect of the reaction gas will be better.

[0032] The above are only the preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention falls within the scope of protection required by the present invention.
