Description

[0001] GAS COOLING AND WASHING EQUIPMENT

[0002] Technical field

[0003] The invention relates to the technical field of water electrolysis hydrogen production, in particular to gas cooling washing equipment (also called gas cooling scrubbing equipment).

[0004] Background art

[0005] The common alkaline water electrolysis hydrogen production device is to generate hydrogen and oxygen by using KOH solution with the electrolysis concentration of about 30 percent, wherein KOH is not consumed in the water electrolysis reaction and is only used as strong electrolyte to promote the water electrolysis reaction. Therefore, the KOH is not needed to be supplemented in the theoretical operation of the equipment, and only the consumed water is needed to be supplemented.

[0006] However, in the actual operation of the product, the normal operating temperature of the electrolytic cell is about 85 °C, and the generated hydrogen and oxygen enter the gasliquid separator together with the electrolyte in a gas- liquid mixed mode. The large number of fine droplets produced when the bubbles break form alkali mist which is discharged with hydrogen and oxygen, and thus the alkali is lost during the operation of producing hydrogen by water electrolysis. When the alkali is lost to a certain extent, the alkali must be supplemented into the system, otherwise, the alkali concentration is affected, and the energy consumption of the unit gas production of the electrolytic cell is affected.

[0007] Moreover, the alkali loss is not only a resource waste, but also can affect the quality of the gas, the purification treatment possibly performed at the downstream and the analysis of the gas quality by the instrument, so that the recycling of the alkali carried in the gas as much as possible is important . For a common water electrolysis hydrogen production device, a washing device is generally provided with raw material water with a certain liquid level, and is provided with an overflow port, when electrolyte raw material water in the oxyhydrogen scrubber adsorbs part of alkali and water vapor, the liquid level of the electrolyte raw material water is higher than the overflow port, and then the electrolyte raw material water enters the separator from the overflow port to supplement alkali.

[0008] However, after the gas enters this type of scrubber, there is often a problem that the gas is not uniformly distributed and flows out too quickly, resulting in insufficient and incomplete washing. Moreover, simply passing the gas into the raw water does not cool the gas enough, and a large exchanger needs to be installed downstream. A hot area gas cooler is used to further cool the gas and remove water. Thus, further improvements are needed for existing gas cooled scrubbing equipment.

[0028] The words expressing the positions and directions described in the present invention are described by taking the drawings as an example, but can be changed according to the needs, and all the changes are included in the protection scope of the present invention.

[0029] Referring to fig. 1, the present invention provides a gas- cooled scrubbing equipment 100 comprising: a first treatment chamber 1, a second treatment chamber 2 and a casing assembly 3.

[0030] Specifically, the first treatment chamber 1 includes a first housing 11 and a first treatment device 12. The first housing 11 is provided with a gas inlet 111. The gas inlet 111 is disposed on a side wall of the first housing 11, preferably disposed in an upper middle position of the first housing 11. The gas-liquid mixture enters the first housing 11 through the gas inlet 111, the first treatment device 12 being used for performing a first treatment on the gas-liquid mixture.

The first housing 11 contains a liquid, such as water and an electrolyte in a gas-liquid mixture. At least a portion of the first cooling assembly 122 is immersed in the electrolyte. The cooling liquid enters the first cooling pipe 1223 from the first coolant gas inlet 1221 and exchanges heat with the liquid in the first housing 11. Then the liquid in the first housing 11 can exchange heat with the gas-liquid mixture to reduce the temperature of said gas-liquid mixture.

The material of the second filling part 2214 may be a ceramic material, a plastic material, a metal material, a polymer material, or the like. A second filling part 2214 in ceramic has the characteristics of corrosion resistance, high-temperature stability and high mechanical strength.

A second filling part 2214 in polymer refers to a filling structure made of a polymer material, such as polypropylene (PP), polyethylene (PE) and the like, and has good corrosion resistance, low density and large surface area, and can provide a large gas-liquid contact area. Preferably, the second treatment device 22 may further include a second cooling assembly 222, the second cooling assembly 222 including a second coolant gas inlet 2221, a second coolant gas outlet 2222, and a second cooling pipe 2223 disposed between the second coolant gas inlet 2221 and the second coolant gas outlet 2222. The second cooling pipe 2223 is disposed in the second housing 21. The second coolant gas inlet 2221 and the second coolant gas outlet 2222 are disposed on the second housing 21. The second cooling assembly 222 is for reducing the temperature of the gas-liquid mixture. In the present embodiment, the second coolant gas inlet 2221 and the second coolant gas outlet 2222 are both provided on the side wall of the second housing 21. The second coolant gas inlet 2221 is provided above the second coolant gas outlet 2222. The cooling liquid enters the second cooling pipe 2223 from the second cooling liquid gas inlet 2221 and exchanges heat with the gas-liquid mixture in the second housing 21.

[0047] The second cooling pipe 2223 may include a second curved section, which may be one or more of spiral, S-shaped, and scroll-shaped. The second curved section may extend the length of the second cooling pipe 2223. This extends the flow path of the cooling fluid within the second cooling pipe 2223, and / or reduces the amount of cooling fluid by further reducing the temperature of the gas-liquid mixture due to a longer heat exchange time between the cooling fluid and the gas-liquid mixture.

[0048] Preferably, the second treatment device 22 may further comprise a gas-liquid separation component 223, the gasliquid separation 223 being configured to separate gas and liquid in the gas-liquid mixture.
