Description

Technical Field

[0001] This utility model relates to the field of gas heat exchange, condensation and separation technology, specifically an integrated equipment for heat exchange, condensation and separation of hydrogen-producing mixed gases. Background Technology

[0002] In traditional steam pyrolysis and steam reforming processes for hydrogen production, the condensation and separation of the hydrogen, carbon dioxide, and steam mixture involves passing the mixture through a condensation device before it enters a gas-liquid separation device.

[0003] Existing technologies involving the process equipment described in this application all employ a single heat exchanger before the gas enters the steam-water separator. These two unit devices not only occupy a large area but also incur high investment and operating costs, and are very cumbersome to operate and control. Therefore, based on the aforementioned technical problems, an integrated heat exchange, condensation, and separation device for hydrogen production mixed gas was designed. Utility Model Content

[0004] To address the problems of complex processes and equipment, large footprint, high equipment investment and operating costs, and cumbersome operation and control, this utility model proposes an integrated equipment for heat exchange, condensation and separation of hydrogen-producing mixed gas.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an integrated heat exchange, condensation and separation device for hydrogen production mixed gas, including a heat exchange component and a separation component. The separation component includes a separation cylinder, with a separation gas inlet and a separation gas outlet at the top. A cyclone separator is provided inside the separation cylinder. The cyclone separator is a hollow structure with open ends from top to bottom. The cyclone separator is used to pass through the separated gas. A gas guiding component is provided on the outside of the cyclone separator. The heat exchange component surrounds the outside of the separation cylinder and is used for heat exchange and cooling. The heat exchange component is provided with a water inlet, a water outlet, a gas inlet, and a gas outlet. The gas outlet is connected to the separation gas inlet. A condensate outlet is provided at the bottom of the separation cylinder.

[0006] Preferably, the heat exchange assembly includes a heat exchange shell, in which multiple hollow heat exchange tubes are arranged side by side, the water inlet and water outlet are connected to the interior of the heat exchange tubes, and the air inlet and air outlet are connected to the heat exchange shell.

[0007] Working principle: This application involves passing chilled water into the heat exchange tubes and steam into the heat exchange shell for heat exchange. After heat exchange, the water is discharged from the outlet, and the cooled mixed gas and steam enter the separation component through the gas outlet. The separation component guides the gas into the cyclone through the gas guide component, and then discharges it through the separated gas outlet. The condensate slides down the side wall to the bottom of the separation cylinder and is then discharged through the condensate outlet.

[0008] Preferably, the gas inlet and gas outlet are located on both sides of the separator cylinder, and a baffle is provided inside the separator cylinder. The baffle is located below the upper opening of the cyclone cylinder. One end of the baffle is located at the upper end of the gas inlet, and the other end of the baffle is located at the lower end of the gas outlet, which further avoids the gas entering the separator cylinder directly exiting from the gas outlet.

[0009] Preferably, the lower end of the cyclone is provided with a conical baffle, the tip of the conical baffle facing upwards, and the conical baffle is 3-5cm away from the lower opening of the cyclone, so that the separated gas is guided into the cyclone through the conical baffle.

[0010] Preferably, the inner wall of the separator is provided with multiple swirling plates, the width of which is 3-5cm and the thickness of which is 3-5mm.

[0011] Preferably, the heat exchange component is provided with multiple water outlets to increase drainage uniformity and efficiency.

[0012] Preferably, the air guiding assembly includes a spiral plate arranged around the cyclone, and the spiral plate is welded to the cyclone.

[0013] Preferably, a safety valve is provided at the top of the separation cylinder, and a pressure gauge is provided on the heat exchange assembly, which increases the safety performance of this application.

[0014] Preferably, the bottom of the separator is a downward-sloping conical structure, the condensate outlet is located at the lowest end of the conical structure, and a valve is provided at the condensate outlet to prevent condensate from accumulating at the bottom of the separator.

[0015] The advantages of this utility model are: This invention achieves heat exchange by introducing cold water into the heat exchange tubes and steam into the heat exchange shell. After heat exchange, the water is discharged from the outlet, and the cooled steam enters the separation component through the gas outlet. The separation component guides the gas into the cyclone through the gas guide component, and then discharges through the separated gas outlet. The condensate slides down the side wall to the bottom of the separation cylinder and is then discharged through the condensate outlet. Through the integrated condensation and separation structure, the footprint of the process equipment is reduced, equipment investment is reduced, operating costs are lowered, and operation and control are convenient. At the same time, the simple operation reduces operating costs.

[0016] 2. The gas inlet and gas outlet of this utility model are located on both sides of the separation cylinder. A partition is provided inside the separation cylinder. The partition is located below the upper opening of the cyclone cylinder. One end of the partition is located at the upper end of the gas inlet, and the other end of the partition is located at the lower end of the gas outlet, which further avoids the gas entering the separation cylinder directly exiting from the gas outlet.

[0017] 3. The cyclone tube of this utility model is provided with a conical baffle at the lower end, the tip of the conical baffle is facing upward, and the conical baffle is 1-2cm away from the opening at the lower end of the cyclone tube.

[0021] 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.

[0022] Please see Figure 1 and Figure 2As shown, the technical solution adopted by this utility model to solve its technical problem is: an integrated heat exchange, condensation and separation device for hydrogen production mixed gas, including a heat exchange component 1 and a separation component 2.

[0027] In another embodiment, the separation cylinder 201 has eight swirling plates 8 attached to its inner wall. The width of the swirling plates 8 is 3-5 cm and the thickness is 3-5 mm. The arrangement of the swirling plates 8 increases convection and improves separation efficiency.

[0028] In another embodiment, the heat exchange component 1 is provided with multiple water outlets 102 to increase drainage efficiency.

[0029] In another embodiment, the air guiding assembly 4 includes a spiral plate arranged around the cyclone 3. The spiral plate is welded to the cyclone 3 and assembled around the cyclone 3.

[0030] In another embodiment, a safety valve 9 is provided at the top of the separation cylinder 201, and a pressure gauge 107 is provided on the heat exchange assembly 1, which increases the safety performance of this application.

[0031] In another embodiment, the bottom of the separator 201 is a downwardly inclined conical structure, and the condensate outlet 5 is located at the lowest end of the conical structure. In actual use, the conical structure has a guiding structure, so that the condensate can be collected at the condensate outlet 5, avoiding the problem of condensate accumulating at the bottom of the separator 201. A valve 501 is provided at the condensate outlet 5.
