[0008] A drip-catching net, which is installed on top of the main container, is used to remove moisture and alkali from the gas;

[0009] A cooling coil is arranged around the main container, with a first cooling section at the bottom for cooling liquids and a second cooling section at the top for cooling gases.

[0010] Furthermore, the first and second cooling sections of the cooling coil are each provided with independent inlets and outlets.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-2 A multifunctional hydrogen and oxygen processing device, comprising

[0023] The main container 1 has a guide tube 11 inside. One end of the guide tube 11 extends out of the main container 1 and has a gas inlet d. The other end of the guide tube 11 extends towards the bottom of the main container 1 and is provided with a diffusion hole 12. Preferably, the diameter of the diffusion hole 12 in this embodiment is 0.5 mm. After the high temperature and high humidity gas is dispersed through the diffusion hole 12, it enters the pure water to complete the initial washing.

[0024] The sieve plate 2 is horizontally arranged inside the main container 1 and above the diffusion holes 12. Preferably, the sieve plate aperture in this embodiment is 0.5-2mm. The diffusion holes 12 and the sieve plate 2 form a stepped distribution structure to increase the gas-liquid contact area.

[0025] The drip-catching net 3 is set on the top of the main container 1 to remove moisture and alkaline solution from the gas. Preferably, the drip-catching net 3 is woven from stainless steel wire into a mesh structure with a mesh size of 0.3mm × 0.3mm, which can intercept residual droplets and remove moisture and trace amounts of alkaline solution from the gas in a secondary manner.

[0026] Cooling coil 4 is arranged around the main container 1. The lower part of the cooling coil 4 is provided with a first cooling section 41 for cooling liquid, and the upper part is provided with a second cooling section 42 for cooling gas. The cooling coil 4 is respectively wrapped around the liquid surface and the gas phase region of the main container 1, and the segmented temperature control is achieved by circulating cooling water. The segmented cooling coil cools the liquid phase and the gas phase separately, reducing energy consumption.

[0027] This utility model provides a flow guide pipe 11 inside the main container 1, and a diffusion hole 12 at one end of the flow guide pipe 11. The diffusion hole 12 and the sieve plate 2 form a stepped distribution structure. Combined with the segmented design of the cooling coil 4, it can simultaneously meet the needs of liquid cooling and gas phase cooling, and improve the gas-liquid contact efficiency and cooling effect.

[0028] In an optional embodiment of this utility model, the first cooling section 41 and the second cooling section 42 of the cooling coil 4 are respectively provided with independent inlets e and outlets f for the cooling medium to enter and exit the cooling coil 4. The two cooling sections are detachably connected by flanges, which facilitates later maintenance and functional expansion.

[0029] In an optional embodiment of this utility model, a hydrophobic coating 21 is provided on the surface of the sieve plate 2, and a gap is left between the sieve plate 2 and the inner wall of the main container 1. Preferably, a 2mm gap is reserved between the sieve plate 2 and the inner wall of the main container 1 to allow the gas to rise evenly. The hydrophobic coating 21 can prevent the alkaline solution from crystallizing and clogging the sieve holes, and the gap can prevent the sieve plate 2 from deforming due to thermal expansion and contraction.

[0030] In an optional embodiment of this utility model, it further includes

[0031] Water inlet b is located in the middle of the side wall of the main container 1; and

[0032] The overflow port a is located above the water inlet b. The overflow port a is connected to the external separator. A float valve can be installed at the water inlet b to control the liquid level sensor. The float valve installed at the water inlet b will automatically replenish water when the liquid level is lower than the set value.

[0033] In an optional embodiment of this utility model, for the convenience of later maintenance and repair, an inspection hole c is provided on the top of the main container 1, and the inspection hole c is sealed by a quick-release flange 5.

[0034] In an optional embodiment of this utility model, the gas outlet g is located on the neck side wall of the main container 1. This arrangement can prevent gas collision and play a role in gas buffering.

[0035] In an optional embodiment of this utility model, the gas outlet g is connected to an outlet pipe 6, and a spiral guide vane 7 is provided inside the outlet pipe 6. The spiral guide vane 7 can reduce the gas flow rate and reduce the impact on downstream equipment.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
