Problems solved by technology

However, if there is hydrogen and oxygen in the gas to be mixed, it is very likely that the local hydrogen and oxygen concentration exceeds the limit, the heat or static electricity generated by the excessive air velocity will cause an explosion accident, and there will be a great safety hazard. Technical implementation is very difficult

Embodiment 1

[0042] Embodiment 1, the air flow dispersing device selects filter material

[0043] All filter materials have the physical characteristics of being porous and selectively permeable to the medium. Taking the honeycomb porous material as an example, since the porous material is immersed in water, hydrogen or auxiliary gas is input from the gas source, and when entering the gas mixing tank 3 from the gas outlet of the hydrogen supply part 1 or the gas outlet of the gas supply part 2, first After the filtering structure, a mixture of water and gas is naturally formed, and a large number of fine air bubbles are generated to realize the cutting and breaking of a single airflow.

[0044] This kind of filter structure can also be a solid particle filter material such as fine gravel laid on the gas outlet of the hydrogen supply part 1 or the gas outlet of the gas supply part 2 . The filter material is submerged below the water surface of the gas mixing tank 3, and covers the gas outl...

Embodiment 2

[0045] Embodiment 2, the air flow dispersing device adopts a honeycomb structure

[0046] The gas outlet of the hydrogen supply part 1 or the gas outlet of the gas supply part 2 can also be connected with a cylinder or box with a honeycomb structure, then the hydrogen or auxiliary gas enters the gas mixture through the pores on the cylinder wall or the box wall In the water body of the tank 3, a large number of air bubbles are formed to realize the cutting and breaking of the airflow.

Embodiment 3

[0047] Embodiment three, the air flow dispersing device selects the stirrer with spiral blade

[0048] The air flow dispersing device can also use an agitator with a helical blade, and the blade agitates the input air flow to realize the cutting and breaking up of the air flow. The power of the agitator is provided by the airflow, and the airflow impinges on the agitator to make the helical blade of the agitator rotate. Of course, the agitator can also be equipped with an external power source, such as a motor, to forcibly drive it to rotate, without the air outlet of the hydrogen supply part 1. 1. The airflow direction of the air outlet of the air supply part 2 is required, and a more high-speed and efficient stirring and mixing effect can also be achieved.

Abstract

The invention relates to a safe mixing device of hydrogen-containing mixed gas and a mixing method thereof. The safe mixing device comprises a hydrogen supply part, a gas supply part and a gas mixingtank capable of containing water, wherein a first gas inlet and a second gas inlet are formed in the lower part of an inner cavity of the gas mixing tank; the first gas inlet is connected with the hydrogen supply part through a pipeline; the second gas inlet is connected with the gas supply part through a pipeline; a gas flow dispersion device is arranged in a water body of the inner cavity of thegas mixing tank; the first gas inlet and the second gas inlet are connected with corresponding gas inlets of the gas flow dispersion device; a gas outlet is formed in the top of the gas mixing tank;when hydrogen gas and auxiliary gas are mixed, the water level in the inner cavity of the gas mixing tank is higher than the height of the gas flow dispersion device; a space for the hydrogen-containing mixed gas needs to be left between the top of the gas mixing tank and the water level. The safe mixing device provided by the invention has the advantages that the initial mixing of the hydrogen gas and the auxiliary gas is performed in water; ignition sources such as static electricity can be isolated; the gas mixing is sufficient; the uniformity is high; the size of the device is small; the use is convenient, and safety and reliability are realized.

Description

technical field [0001] The invention relates to a gas preparation device, in particular to a hydrogen-containing mixed gas preparation device and a preparation method. Background technique [0002] Hydrogen has a unique effect on the treatment of cerebrovascular diseases, tumors and other diseases. Hydrogen has great potential for anti-aging and health care. The application of hydrogen in welding, new fuel cells and other broader fields is also developing rapidly. However, when the hydrogen gas concentration in the air is 4% to 75%, the frictional heat generated by the opening of the valve, the static electricity formed by the high-speed air flow, and the static electricity of the human body may instantly cause an explosion. Furthermore, the pressure of the hydrogen-containing mixed gas becomes more flammable and explosive. Therefore, the use of hydrogen under pressure is quite dangerous. [0003] There is an existing patent No. CN201510189472.0, and the Chinese invention ...
