[0025] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0026] like Figures 1 to 5 As shown, this embodiment provides an ethanol gas humidification and mixing device.

[0027] The mixing tank 1 includes a tank body 120 and a cover 110 installed at the opening of the tank body 120; ten clamps 111 are installed around the edge of the opening on the outer wall of the tank body 120, and the cover 110 is sealed to the tank body 120 through these clamps 111, making the mixing tank 1 a sealed container.

[0028] Includes control frame 2, which is vertically fixed to one side of mixing tank 1.

[0029] The side walls of the housing 120 are respectively provided with an air inlet 122, an air outlet 121, a first sampling port 123, and a second sampling port 124.

[0030] It includes an air intake pipe 7, one end of which is connected to the air inlet 122, and the other end of which is connected to the outside. A valve is installed on the air intake pipe 7, which is used to output gas and then input new air.

[0031] Includes an outlet pipe 5, one end of which is connected to an outlet 121, and the other end of which is the output end. A third blower 6 is connected in series with the outlet pipe 5. The outlet pipe 5 is used to output the prepared mixed gas. A valve also needs to be installed on the outlet pipe 5 when there is no container at the end of the outlet pipe 5.

[0032] The system includes a sampling device 3, which is fixedly mounted on a control frame 2. The sampling device 3 includes a first sampler 310 and a second sampler 320. In this embodiment, the first sampler 310 and the second sampler 320 are equipped with GD-100 fixed gas detectors and use a pump-suction sampling method to detect ethanol concentration. The system also includes a first sampling tube 8 and a second sampling tube 9. One end of the first sampling tube 8 is connected to a first sampling port 123, and the other end of the first sampling tube 8 is connected to the first sampler 310. One end of the second sampling tube 9 is connected to a second sampling port 124, and the other end of the second sampling tube 9 is connected to the second sampler 320.

[0033] The second sampling port 124 is located far from the first sampling port 123. Compared with a single sampler, setting up two samplers at the same time makes it easier to collect and measure the ethanol concentration at different locations far apart in the chamber 120, thereby judging the uniformity of gas mixing. When the first sampler 310 and the second sampler 320 maintain the same or very close values ​​for a long time, it can be judged that the gas in the mixing chamber 1 has been fully mixed and uniform.

[0034] A stirring device 10 is installed inside the housing 120. The stirring device 10 includes a U-shaped stirring channel 1011, which is horizontally fixed to the bottom of the housing 120. The two ends of the stirring channel 1011 are the inlet end and the outlet end, respectively. A first fan 1012 is installed at the inlet end of the stirring channel 1011, and a second fan 1013 is installed at the outlet end. The impellers of the first fan 1012 and the second fan 1013 rotate in opposite directions during operation. The first fan 1012 draws air into the stirring channel 1011, and the second fan 1013 discharges the gas in the stirring channel 1011 outward. This allows the gas to collide, bend, and mix during the process of passing through the stirring channel 1011, thereby achieving the effect of uniform gas mixing.

[0035] The control frame 2 is equipped with a stirring fan regulating switch 210. The stirring fan regulating switch 210, the first fan 1012 and the second fan 1013 form a series circuit. The speed of the first fan 1012 and the second fan 1013 can be adjusted as needed by the fan regulating switch.

[0036] A partition 13 is vertically installed inside the housing 120. One side of the partition 13 is fixed to the inner wall of the housing 120, and the other side is fixed to the U-shaped inner bend of the mixing channel 1011. The two openings of the mixing channel 1011 are respectively located on both sides of the partition 13. The partition 13 separates the two openings of the mixing channel 1011 from each other. After the gas leaves the outlet end of the mixing channel 1011, it needs to travel a longer distance before re-entering the inlet end of the mixing channel 1011, which further improves the gas mixing effect, eliminates gas stratification, and makes the mixing more uniform.

[0037] The tank cover 110 has a first injection port 112 and a second injection port 113, and sealing caps are installed on the first injection port 112 and the second injection port 113 respectively for sealing. A first storage box 11 and a second storage box 12 are also installed inside the tank body 120. The bottoms of the first storage box 11 and the second storage box 12 are fixedly connected to the stirring channel 1011. The opening of the first storage box 11 is located directly below the first injection port 112, and the opening of the second storage box 12 is located directly below the second injection port 113. The first storage box 11 is used to store water, and the second storage box 12 is used to store ethanol. The evaporation of water in the first storage box 11 will increase the humidity inside the stirring tank 1, and the evaporation of ethanol in the second storage box 12 will increase the ethanol content inside the stirring tank 1. When the humidity is insufficient, water can be added through the first injection port 112 to increase the humidity; when the ethanol content is low, ethanol can be added through the second injection port 113 to increase the content.

[0038] Each of the first liquid storage box 11 and the second liquid storage box 12 is provided with an absorbent cotton. The outer shells of the first liquid storage box 11 and the second liquid storage box 12 are densely covered with through holes, thereby improving the evaporation efficiency of water or the volatilization efficiency of ethanol.

[0039] It includes a humidity detector 4, which is installed on the lid 110. The sensor of the humidity detector 4 is located inside the lid 110 to measure the humidity value inside the mixing tank 1. The humidity detector 4 is selected with a display screen for easy and intuitive reading of the humidity.

[0040] How to use this embodiment:

[0041] First, add an appropriate amount of water to the first storage box 11 through the first injection port 112, and add an appropriate amount of ethanol to the second storage box 12 through the second injection port 113. After adding the ethanol, the sealing plug of the injection port should be closed.

[0042] Turn on the first fan 1012 and the second fan 1013. The two fans quickly agitate the air in the mixing box 1, causing water and ethanol to be converted into gaseous state. The air, gaseous water, and gaseous ethanol are continuously mixed through the mixing channel 1011, thereby eliminating gas stratification and making the mixture more uniform.

[0043] Observe the humidity detector 4. When the humidity is insufficient, water can be added through the first injection port 112 to increase the humidity. Observe the sampling device 3. When the ethanol content is low, ethanol can be added through the second injection port 113 to increase the ethanol content.

[0044] When the humidity detector 4 displays the desired value, stop adding water; when the values ​​of the first sampler 310 and the second sampler 320 in the sampling device 3 are nearly identical and both reach the desired value, stop adding ethanol. After all parameters stabilize, the gas mixture in the mixing tank 1 is now the desired mixture.

[0045] Turn on the third fan 6 to evacuate the mixing tank 1. The extracted mixed gas is injected into a container for storage and use, thus completing the preparation and extraction of humidified mixed ethanol gas.

[0046] Finally, remove the container, turn on the third fan 6, and vent the remaining gas in the mixing tank 1 through the air outlet pipe 5. Then, open the valve of the air inlet pipe 7 to inject fresh air into the mixing tank 1.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
