Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a rapid cooling heat exchanger for cooling high-temperature gases. Background Technology

[0002] Heat exchangers are key equipment for heat exchange. Their main function is to perform heat exchange, ensuring that heat is transferred from high-temperature fluids to low-temperature fluids. Heat exchangers are widely used in chemical production.

[0003] Currently, during the production of activated carbon, a large amount of high-temperature gas is generated during the combustion of the carbon blank. In order to effectively utilize the heat energy in the high-temperature gas, it is essential to install a heat exchanger along the high-temperature gas emission path. However, existing tower heat exchangers have certain drawbacks in use. Because the water storage device inside the tower heat exchanger can only exchange heat energy with the high-temperature gas passing around it, the utilization rate of heat energy in the subsequent output gas is significantly reduced.

[0004] In view of this, a rapid cooling heat exchanger for cooling high-temperature gases was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A rapid cooling heat exchanger for cooling high-temperature gases includes a protective shell and a rapid cooling heat exchange mechanism installed inside the protective shell. The rapid cooling heat exchange mechanism includes an inlet pipe and an exhaust pipe fixedly installed at the bottom of both ends of the protective shell. A first guide pipe is installed at the top of the inlet pipe, and a second guide pipe is installed at the top of the exhaust pipe. U-shaped tubes are installed at the top of both the first and second guide pipes. Heat exchange arc tubes are installed at the top of both U-shaped tubes. A liquid exchange tank is fixedly installed outside the two heat exchange arc tubes. Two symmetrically distributed partitions are fixedly installed inside the liquid exchange tank. End pipes are fixedly installed on the inner side of the two partitions, and the partitions are fixedly installed outside the heat exchange arc tubes. A first liquid exchange pipe and a second liquid exchange pipe are fixedly installed at the bottom of the liquid exchange tank.

[0007] In a preferred embodiment, the present invention may be further configured such that the rapid cooling heat exchange mechanism further includes a transfer bottom pipe, and the transfer bottom pipe is connected to the second guide pipe and the first guide pipe that are spaced apart.

[0008] In a preferred embodiment, the present invention can be further configured such that: two symmetrically distributed annular gaskets are fixedly installed in the middle of the inner cavity of the U-shaped tube, and a first transmission component and a second transmission component are movably installed inside the two U-shaped tubes respectively.

[0009] In a preferred embodiment, the present invention can be further configured such that: both the first transmission component and the second transmission component are composed of an extended shaft, a fan blade, and an impeller, and the fan blade is located inside a U-shaped tube, and two anti-overflow gaskets are installed in the middle of the extended shaft.

[0010] In a preferred embodiment, the present invention may be further configured such that the rapid cooling heat exchange mechanism further includes a heat exchange flow pipe connected to the second liquid exchange pipe and the first liquid exchange pipe, which are spaced apart.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model improves the efficiency of heat exchange between the aqueous solution and the gas by installing multiple sets of quenching heat exchange mechanisms evenly distributed along the path of high-temperature gas transfer. When the high-temperature gas is transferred along the circulating pipeline, the aqueous solution and the gas are kept at the same flow rate, thereby improving the efficiency of heat exchange between the aqueous solution and the gas and further enhancing the utilization rate of heat exchange between the aqueous solution and the gas.

[0012] 2. This utility model movably installs the first and second transmission components inside the two U-shaped tubes respectively. As the high-temperature gas passes through the two U-shaped tubes in sequence, the first and second transmission components will maintain the same speed and rotate in opposite directions. Finally, the aqueous solution will be actively transferred during the heat exchange, which improves the flow of the aqueous solution and gas at the same speed and improves the heat exchange efficiency.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0017] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a rapid cooling heat exchanger for cooling high-temperature gases.

[0018] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a rapid cooling heat exchanger for cooling high-temperature gas, including a protective shell 100 and a rapid cooling heat exchange mechanism 200 installed inside the protective shell 100. The protective shell 100 is used to provide thermal insulation protection for the high-temperature gas, and the rapid cooling heat exchange mechanism 200 is used to keep the aqueous solution and the airflow circulating at the same speed and accelerate the heat exchange efficiency.

[0019] The rapid cooling heat exchange mechanism 200 includes an inlet pipe 210 and an exhaust pipe 220 fixedly installed at the bottom of both ends of the protective shell 100. A first guide pipe 290 is installed at the top of the inlet pipe 210, and a second guide pipe 230 is installed at the top of the exhaust pipe 220. U-shaped pipes 240 are installed at the top of both the first guide pipe 290 and the second guide pipe 230. Heat exchange arc pipes 250 are installed at the top of both U-shaped pipes 240. A liquid exchange tank 260 is fixedly installed outside the two heat exchange arc pipes 250. Two symmetrically distributed partitions 2603 are fixedly installed inside the liquid exchange tank 260. End pipes 2604 are fixedly installed on the inner side of the two partitions 2603, and the partitions 2603 are fixedly installed outside the heat exchange arc pipes 250. A first liquid exchange pipe 2601 and a second liquid exchange pipe 2602 are fixedly installed at the bottom of the liquid exchange tank 260.

[0020] The number of multiple rapid cooling heat exchange mechanisms 200 is increased according to the output of high-temperature airflow, and an external exhaust pipe is connected to the intake pipe 210. As the high-temperature gas enters the first guide pipe 290 from the intake pipe 210, the first guide pipe 290 guides the gas to one of the U-shaped pipes 240. The second transmission component 2403 in the U-shaped pipe 240 is assisted by the airflow until an impeller in the second transmission component 2403 continuously pressurizes the aqueous solution in the second liquid exchange pipe 2602. The pressurized aqueous solution enters the first liquid exchange pipe 2601 through the end pipe 2604. As the airflow passes through the heat exchange arc pipe 250 and enters another U-shaped pipe 240, the first transmission component 2402 rotates at the same speed and in the opposite direction to the second transmission component 2403. The aqueous solution entering the first liquid exchange pipe 2601 is actively output. By increasing the contact area at the convergence point of the airflow and the aqueous solution, efficient heat energy conversion is achieved under the action of circulation and transfer.

[0021] Example 2: Combination Figure 3 and Figure 4 As shown, in the above embodiment, the rapid cooling heat exchange mechanism 200 further includes a transfer bottom pipe 270, and the transfer bottom pipe 270 is connected to the spaced second guide pipe 230 and the first guide pipe 290, and to the heat exchange flow pipe 280 connected to the spaced second liquid exchange pipe 2602 and the first liquid exchange pipe 2601. Two symmetrically distributed ring gaskets 2401 are fixedly installed in the middle of the inner cavity of the U-shaped tube 240, and the first transmission component 2402 and the second transmission component 2403 are respectively movably installed inside the two U-shaped tubes 240. Both the first transmission component 2402 and the second transmission component 2403 are composed of an extended shaft, a fan blade, and an impeller. The fan blade is located inside the U-shaped tube 240, and two anti-overflow gaskets are installed in the middle of the extended shaft.

[0022] Multiple sets of first liquid exchange pipes 2601, first guide pipes 290, and second guide pipes 230 are connected by multiple heat exchange pipes 280 and multiple transfer bottom pipes 270. The aqueous solution required for heat exchange can flow along the inner cavity of multiple liquid exchange tanks 260. At the same time, after the airflow passes through multiple liquid exchange tanks 260 in sequence, the heat energy in the airflow will be continuously exchanged, and the gas will be effectively cooled. The cooled airflow will be released from the exhaust pipe 220 and transferred to the next stage.

[0023] The working principle and usage process of this utility model are as follows: The external high-temperature gas discharge pipe is connected to the inlet pipe 210 in advance. When the high-temperature gas enters the first guide pipe 290 through the inlet pipe 210, the first guide pipe 290 will guide the high-temperature gas. Finally, the guided high-temperature gas will flow into the interior of a heat exchange arc pipe 250 through one of the U-shaped pipes 240. At the same time, the external water pipe is connected to the second liquid exchange pipe 2602, and the heat exchange flow pipe 280 is used to connect the first liquid exchange pipe 2601 to another second liquid exchange pipe 2602. After the water fills the cavity formed by the liquid exchange tank 260, two partitions 2603, and two heat exchange arc tubes 250, the two cavities are connected by the end pipe 2604. As the gas passes through the cavity inside the two partitions 2603, the second transmission component 2403, driven by the airflow, rotates forward and continuously pressurizes the water in the cavity formed by one of the partitions 2603 and the liquid exchange tank 260. The pressurized water then flows through the end pipe 2604 into another cavity of the other partition 2603 and the liquid exchange tank 260. At the same time, after the gas is heated and enters the inner cavity of another U-shaped tube 240, the first transmission component 2402 reverses direction, thereby accelerating the discharge speed of the aqueous solution in the other cavity formed by the other partition 2603 and the liquid exchange tank 260. Finally, the aqueous solution after primary heat exchange flows through the heat exchange flow pipe 280 into the inner cavity of the next-stage liquid exchange tank 260. This multi-stage and progressive heat exchange method improves the heat exchange efficiency of the high-temperature gas and simultaneously increases the cooling rate of the gas.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
