Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen treatment, in particular to a hydrogen treatment device with high efficiency washing, cooling and recycling. Background Art

[0002] There are many methods for industrial production of caustic soda at present. For the ion membrane caustic soda production method, hydrogen will be generated during the production process. Hydrogen is a flammable and explosive gas, so it needs to be handled in a timely manner. In order to reduce and avoid the accumulation of sparks, static electricity and other phenomena during the caustic soda production process, hydrogen treatment equipment has also become a relatively important supporting facility.

[0003] Existing hydrogen processing devices typically use cooling water to spray, wash, and cool hydrogen in a scrubber. However, the cooling water is unevenly distributed within the scrubber, affecting the interaction between water and airflow, resulting in abnormal water distribution, which in turn affects the cooling effect of the hydrogen in the scrubber. Furthermore, the liquid separated by the gas-liquid separator cannot be recycled. Therefore, we have introduced a new, highly efficient, scrubbing, cooling, and recycling hydrogen processing device. Utility Model Content

[0004] The main purpose of the utility model is to provide a hydrogen processing device with high efficiency washing, cooling and recycling, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A hydrogen processing device with high-efficiency washing, cooling and recycling comprises a washing tower, a spray mechanism fixedly mounted on the upper inner portion of the washing tower, an air outlet pipe fixedly mounted on the upper end of the washing tower, an end of the air outlet pipe remote from the spray mechanism being flange-connected to a hydrogen compressor, an end of the hydrogen compressor remote from the air outlet pipe being flange-connected to a gas-liquid separator, an end of the gas-liquid separator remote from the hydrogen compressor being flange-connected to a heat exchanger, an end of the heat exchanger remote from the gas-liquid separator being flange-connected to a hydrogen distribution platform, and a circulation mechanism fixedly mounted on the lower end of the gas-liquid separator.

[0007] Preferably, the spray mechanism includes a water collecting ring, a plurality of spray heads are fixedly mounted on the lower end of the water collecting ring, a water inlet pipe is fixedly connected to the left portion of the outer surface of the water collecting ring, and a connection interface is fixedly connected to the left end of the water inlet pipe.

[0008] Preferably, the outer surface of the water collecting ring is fixedly connected to the inner wall of the washing tower, the water inlet pipe is connected to the washing tower through insertion, and the water inlet pipe is communicated with the interior of the water collecting ring.

[0009] By adopting the above technical solution: the external cooling water pipe can be connected to the connection interface, the cooling water can be sent into the water collecting ring through the water inlet pipe, and then sprayed out from top to bottom by several nozzles below the water collecting ring.

[0010] Preferably, the plurality of shower heads are distributed in a circular array, and the plurality of shower heads are all inclined at an angle.

[0011] By adopting the above technical solution: since several spray heads are distributed in a circular array and several spray heads are inclined, the cooling water can fully contact with the hydrogen and carry out heat exchange, absorption and other reactions, making the washing process more efficient and thorough, and avoiding local overheating or overcooling.

[0012] Preferably, the circulation mechanism includes a cooler, a No. 1 connecting pipe is installed at the left end of the cooler, a No. 2 connecting pipe is installed at the right end of the cooler, a filter is installed at the end of the No. 2 connecting pipe away from the cooler, and a mounting pipe is installed at the upper end of the filter.

[0013] Preferably, the end of the No. 1 connecting pipe away from the cooler is fixedly connected to the hydrogen compressor, and the No. 1 connecting pipe is connected to the interior of the No. 2 connecting pipe through the cooler.

[0014] By adopting the above technical solution, the circulating fluid can be cooled by the cooler and then enter the hydrogen generator for circulation.

[0015] Preferably, the filter is fixedly mounted together with the gas-liquid separator via a mounting pipe.

[0016] By adopting the above technical solution, impurities in the circulating fluid can be filtered through the filter.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a spray mechanism, the external cooling water pipe is connected to the connection interface, and the cooling water is sent into the water collection ring through the water inlet pipe. Then, it is sprayed by several spray heads below the water collection ring, so that the cooling water can spray and wash the hydrogen at about 80°C from the electrolysis process from top to bottom and cool it to 40°C. Because the several spray heads are distributed in a ring array and are all inclined at an angle, the cooling water can fully contact with the hydrogen and carry out heat exchange, absorption and other reactions, making the washing process more efficient and thorough, and avoiding local overheating or overcooling;

[0019] 2. By setting up a circulation mechanism, the hydrogen after washing and cooling through the washing tower enters the hydrogen compressor for pressurization, passes through the gas-liquid separator and heat exchanger in sequence, and is then sent to each hydrogen user through the hydrogen distribution station. The circulating liquid coming out of the bottom of the gas-liquid separator can be filtered through the filter and then enter the cooler through the No. 2 connecting pipe for cooling. The cooled circulating liquid enters the hydrogen compressor through the No. 1 connecting pipe for recycling, which can avoid the waste of water resources and effectively save the utilization of water resources.

[0028] See also Figures 1-4 , the utility model provides a technical solution:

[0029] A hydrogen processing device with high-efficiency washing, cooling and recycling comprises a washing tower 1, a spray mechanism 2 is fixedly installed on the upper part of the washing tower 1, an outlet pipe 3 is fixedly installed on the upper end of the washing tower 1, an end of the outlet pipe 3 away from the spray mechanism 2 is flange-connected to a hydrogen compressor 4, an end of the hydrogen compressor 4 away from the outlet pipe 3 is flange-connected to a gas-liquid separator 5, an end of the gas-liquid separator 5 away from the hydrogen compressor 4 is flange-connected to a heat exchanger 6, an end of the heat exchanger 6 away from the gas-liquid separator 5 is flange-connected to a hydrogen distribution platform 7, and a circulation mechanism 8 is fixedly installed on the lower end of the gas-liquid separator 5.

[0030] In this embodiment, the spray mechanism 2 includes a water collecting ring 21, and several spray heads 22 are fixedly installed at the lower end of the water collecting ring 21. A water inlet pipe 23 is fixedly connected to the left part of the outer surface of the water collecting ring 21, and a connection interface 24 is fixedly connected to the left end of the water inlet pipe 23. The outer surface of the water collecting ring 21 is fixedly connected to the inner wall of the washing tower 1, the water inlet pipe 23 is interlaced with the washing tower 1, and the water inlet pipe 23 is connected to the inside of the water collecting ring 21. Several spray heads 22 are distributed in a circular array, and several spray heads 22 are all at an inclined angle.

[0031] Through the above scheme: the external cooling water pipe is connected to the connection interface 24, the cooling water is sent into the water collecting ring 21 through the water inlet pipe 23, and then sprayed out by several spray heads 22 below the water collecting ring 21, so that the cooling water can spray and wash the hydrogen at about 80°C from the electrolysis process from top to bottom and cool it to 40°C. Since the several spray heads 22 are distributed in a ring array and the several spray heads 22 are all at an inclined angle, the cooling water can fully contact with the hydrogen and carry out heat exchange, absorption and other reactions, making the washing process more efficient and thorough, and avoiding local overheating or overcooling.

[0032] In this embodiment, the circulation mechanism 8 includes a cooler 71, a No. 1 connecting pipe 72 is installed at the left end of the cooler 71, a No. 2 connecting pipe 73 is installed at the right end of the cooler 71, a filter 74 is installed at the end of the No. 2 connecting pipe 73 away from the cooler 71, and a mounting pipe 75 is installed at the upper end of the filter 74. The end of the No. 1 connecting pipe 72 away from the cooler 71 is fixedly connected to the hydrogen compressor 4, the No. 1 connecting pipe 72 is connected to the inside of the No. 2 connecting pipe 73 through the cooler 71, and the filter 74 is fixedly installed together with the gas-liquid separator 5 through the mounting pipe 75.

[0033] According to the above scheme, the hydrogen after washing and cooling through the washing tower 1 enters the hydrogen compressor 4 for pressurization, passes through the gas-liquid separator 5 and the heat exchanger 6 in sequence, and is then sent to various hydrogen users through the hydrogen distribution station 7. The circulating liquid coming out of the bottom of the gas-liquid separator 5 can be filtered through the filter 74 and then enter the cooler 71 through the second connecting pipe 73 for cooling. The cooled circulating liquid enters the hydrogen compressor 4 through the first connecting pipe 72 for recycling, which can avoid the waste of water resources and effectively save the utilization of water resources.

[0034] It should be noted that the present invention is a hydrogen processing device for efficient washing, cooling and recycling. During use, the high-temperature hydrogen of about 80°C generated in the electrolysis process needs to be effectively cooled by the cooling system. The external cooling water pipe is connected to the connection interface 24 to ensure that the cooling water can flow in smoothly. The cooling water is introduced into the water collecting ring 21 through the water inlet pipe 23, and then sprayed through a plurality of spray heads 22 distributed in a circular array below the water collecting ring 21. These spray heads 22 are set at a certain inclination angle to ensure that the cooling water can fully contact with the hydrogen to achieve efficient heat exchange and cooling effects. During the spraying process, the cooling water is sprayed from top to bottom onto the hydrogen to warm it up. The temperature is reduced to about 40°C. This process not only cools the hydrogen, but also removes the saturated water and alkaline substances entrained in the hydrogen through washing. The treated hydrogen then enters the hydrogen compressor 4 through the outlet pipe 3 for pressurization. The pressurized hydrogen will pass through the gas-liquid separator 5 and the heat exchanger 6 in sequence, and finally be distributed to various hydrogen users through the hydrogen distribution station 7. During the gas-liquid separation process, the circulating liquid discharged from the bottom will first pass through the filter 74 to filter out impurities, and then flow into the cooler 71 through the No. 2 connecting pipe 73 for cooling. The cooled circulating liquid will then flow back to the hydrogen compressor 4 through the No. 1 connecting pipe 72, realizing the recycling of water resources, thereby effectively saving water resources and reducing waste.
