The sidewall of second section 52 covers a portion of second air outlet 32. .
This gas humidifying device is when carrying out the humidification to gas, has held water in the liquid storage pot 1, and the surface of water is not higher than the second gas outlet of air inlet vessel 3, treats that the gas of humidification leads to gas humidifying device in through intake pipe 2, through the effect of gas exploder 4, forms a large amount of small bubbles and enters into air inlet vessel 3, greatly increased the area of contact of gas and water, makes gas obtain abundant moist. When the gas in the gas inlet container 3 is discharged from the second gas outlet 32 at the top, because the gas flow velocity is fast, the pressure near the second gas outlet 32 is low, when the gas flow velocity reaches a certain degree, the water in the water spray pipe 5 is sprayed out from the upper end of the water spray pipe 5 under the action of the gas pressure difference, and is blown into mist by the gas flow discharged from the second gas outlet 32, the gas flow is mixed with the water mist, the gas discharged from the second gas outlet 32 is humidified for the second time, the humidifying effect is further improved, and the gas after the second humidification is discharged from the first gas outlet 11 at the top of the liquid storage tank 1, so that the gas is sufficiently humidified.

When the flow of the gas entering the gas inlet pipe is small, the flow rate of the gas at the second gas outlet 32 of the gas inlet container 3 is small, so that the difference between the gas pressure at the second gas outlet 32 and the gas pressure at the liquid level in the liquid storage tank 1 is small according to the Bernoulli principle, and the water in the water spray pipe 5 is not enough to be sprayed out under the action of the pressure difference.

In this embodiment, the liquid storage tank 1 is cylindrical, and the first air outlet 11 is located in the middle of the top of the liquid storage tank 1.

In the above implementation manner, the liquid storage tank 1 is arranged as the tank body 12 and the top cover 13, so that the liquid can be conveniently arranged in the liquid storage tank 1 through the detachable connection between the tank body 12 and the top cover 13, and the liquid storage tank 1 can be conveniently processed and manufactured.
In this embodiment, in order to conveniently replenish the liquid in the liquid storage tank 1, the top of the tank body 12 is further provided with a water inlet 123. The water inlet 123 is sealed by a plug.
In the using process, the water in the liquid storage tank 1 can be gradually reduced, and the water inlet 123 is arranged, so that water can be conveniently added into the liquid storage tank 1 when the water quantity is insufficient.
Illustratively, the fluid reservoir tank 1 further includes a clip 14, the tank 12 having a first outer flange 122 at a top end thereof, the top cap 13 having a second outer flange 132 at a bottom end thereof, the first outer flange 122 and the second outer flange 132 being connected by the clip 14.
In the above embodiment, the clip 14 is engaged with the first outer flange 122 and the second outer flange 132, so that the can body 12 and the top cover 13 can be easily disassembled.
In this embodiment, the band 14 includes two symmetrical halves 141 with the same structure, each half 141 has a semi-annular groove 1411 on its inner wall, and each half 141 has a connecting flange (not shown) on its outer wall near its two ends. The two half rings 141 are detachably connected together by a connecting flange. The first outer flange 122 and the second outer flange 132 are each located in the semi-annular grooves 1411 of the two half rings 141.
In some examples, the connection flanges in the two half rings 141 are removably connected by bolts and nuts.
In other examples, the two half rings 141 are hinged at one end and detachably connected at the other end by bolts.
With continued reference to FIG. 1, the fluid storage tank 1 further illustratively includes a fluid level gauge 16, the fluid level gauge 16 being positioned within the fluid storage tank 1, and the fluid level gauge 16 being coupled to an interior wall of the fluid storage tank 1.
Through setting up level gauge 16, conveniently detect the height of the inside surface of water of this liquid storage pot 1, avoid the inside water yield of liquid storage pot 1 not enough, the surface of water is low excessively, leads to the difference in height of the upper end of spray pipe 5 and the surface of water too big, and water is difficult to spout from spray pipe 5. And the phenomenon that the water is excessively added and overflows the second air outlet 32 of the air inlet container 3 when water is added is avoided.
To facilitate sensing the level of the fluid reservoir 1, a fluid level gauge 16 is disposed on an inner wall of the tank 12 at the first opening 121.
In this embodiment, the air inlet pipe 2 is a straight pipe, an air inlet pipe mounting hole 17 is formed in the side wall of the liquid storage tank 1, and the air inlet pipe 2 is hermetically inserted into the air inlet pipe mounting hole 17.

Optionally, a filter screen 22 is provided in the intake pipe 2.
In the above implementation, the filter screen 22 is arranged to filter the gas entering the gas inlet pipe 2, so as to prevent the gas entering the gas inlet pipe 2 from damaging the structure of the gas blaster 4 and the like due to the impurities entering the gas blaster 4.
Optionally, a gas valve is connected to the first end of the gas inlet pipe 2.
In the above implementation manner, the air input of the reaction gas entering the gas humidifying device can be controlled and adjusted through the adjusting valve, so that the gas flow of the reaction gas is reasonably controlled, and the gas flow meets the actual requirement.
In practical use, when the required reaction gas flow is small, the gas valve connected with the gas inlet pipe 2 is controlled, so that the gas flow entering the gas inlet pipe 2 meets the required size.
When the gas flow in the gas inlet pipe 2 is small, the gas flow speed discharged from the second gas outlet 32 of the gas inlet container 3 is small, the gas pressure difference between the second gas outlet 32 and the liquid level in the liquid storage tank 1 is not enough to enable water to be sprayed out from the upper end of the water spray pipe 5, but the gas flow forms tiny bubbles to be contacted with the water under the action of the gas blaster 4, and the required wetting degree is enough to be achieved.
When the required reaction gas flow is large, the gas flow entering the gas inlet pipe 2 is increased by controlling the gas valve connected with the gas inlet pipe 2.
At this time, the gas is humidified in the gas inlet container 3, the flow rate of the gas discharged from the second gas outlet 32 of the gas inlet container 3 is also high, and the pressure difference between the second gas outlet 32 and the liquid level in the liquid storage tank 1 is increased, so that water is sprayed out from the top end of the second section 52 to humidify the gas for the second time, thereby avoiding the situation that the gas cannot be sufficiently humidified due to too high flow rate of the gas, improving the humidification degree of the gas, and ensuring that the humidity of the gas can meet the requirement.
With continued reference to fig. 1, the inner diameter of the air inlet container 3 decreases from the bottom end to the top end in at least some regions.
In the above embodiment, when the gas passes through the gas inlet container 3, the flow rate of the gas is gradually increased in the atmosphere in which the inner diameter of the gas inlet container 3 is gradually decreased by the venturi effect as the inner diameter of the gas inlet container 3 is gradually decreased. When the gas reaches the position with the smallest inner diameter of the gas inlet container 3, the flow velocity of the gas reaches the largest, the gas pressure at the second gas outlet 32 of the gas inlet container 3 is further reduced, and therefore the difference between the gas pressure at the second gas outlet 32 and the gas pressure at the liquid level in the liquid storage tank 1 is increased, water in the water spray pipe 5 can be sprayed out smoothly, and the gas is moistened for the second time.
Optionally, the air intake vessel 3 comprises a first cylindrical barrel 33, a conical barrel 34 and a second cylindrical barrel 35. The inner diameter of the top end of the conical cylinder 34 is smaller than that of the bottom end, the bottom end of the conical cylinder 34 is connected with the top end of the first cylindrical cylinder 33, the liquid inlet 31 is positioned at the bottom end of the first cylindrical cylinder 33, and the outer wall of the first cylindrical cylinder 33 is connected with the inner wall of the liquid storage tank 1. The top end of the conical cylinder 34 is connected with the bottom end of the second cylindrical cylinder 35, and the second air outlet 32 is positioned at the top end of the second cylindrical cylinder 35.
In the above implementation, the tapered tube 34 in the middle of the air inlet container 3 can make the flow velocity gradually increase after the air inlet container 3, so that the air pressure at the second air outlet 32 of the air inlet container 3 can be reduced to make the water be sprayed out from the water spray pipe 5.
In this embodiment, the air inlet container 3 is an integrally molded structure.
In other embodiments, the first cylindrical barrel 33, the tapered barrel 34, and the second cylindrical barrel 35 may be welded.
Illustratively, the air intake reservoir 3 is disposed coaxially with the fluid reservoir 1. Can make the water smoke that blows out in the spray pipe 5 in the air inlet vessel 3 disperse around to the inside of liquid storage pot 1 uniformly like this for the air current can be more even with the contact between the water smoke, so that further improve this gas humidifying device's humidification effect, the water droplet that does not mix with the air current falls into aquatic.
As an example, the taper of the tapered cylinder 34 is 1:5-1:3, the tapered cylinder 34 has a converging effect on the gas in the gas inlet container 3, the converging effect on the gas is smaller when the taper is too small, and the gas flow is discharged from the second gas outlet 32 at a lower speed.
Illustratively, the conical barrel 34 has an inner diameter at its top end of 25mm to 35 mm. The inner diameter of the top end of the tapered tube 34 affects the flow rate and flow rate of the gas discharged from the gas inlet container 3, and if the inner diameter is too small, the flow rate of the gas is too small, and if the inner diameter is too large, the flow rate of the gas is reduced, so that the water in the water spray pipe 5 is difficult to spray.
Alternatively, the second segment 52 is curved in a 90 ° arc, and the tangential direction of the upper end of the second segment 52 is perpendicular to the axis of the air intake container 3.
In the above implementation, the second segment 52 bent into a 90 ° arc facilitates smooth passage of water, and when the water is sprayed from the second segment 52, the water can impact with the airflow discharged from the air inlet container 3, so as to be blown away by the airflow.
Illustratively, the outer wall of the first segment 51 is welded to the inner wall of the tank 1, and the outer wall of the second segment 52 is welded to the inlet vessel 3.
In this embodiment, the water spray pipe 5 is an integrally formed structural member.
By way of example, the inner diameter of the water jet 5 is 15mm to 25 mm. If the inner diameter of the water spray pipe 5 is too large, the water in the water spray pipe 5 is difficult to be sprayed by the pressure difference, and if the inner diameter is too small, the flow rate of the sprayed water is too small, thereby reducing the effect of secondary wetting.
The water spray pipe 5 is illustratively a steel pipe or a plastic pipe.
Optionally, the gas humidifying device further comprises a heater 6, the heater 6 is located inside the liquid storage tank 1 and right below the gas inlet container 3, and the heater 6 is inserted into the inner wall of the liquid storage tank 1.

Illustratively, the heater 6 is an electric heater.
In this embodiment, the power of the heater 6 is adjustable. The power of the heater 6 is adjustable, so that the gas humidifying device can be in different temperature environments according to specific use requirements, and humidified gas with different temperatures is obtained.
In this embodiment, for the convenience of installation, the sidewall of the liquid storage tank 1 is provided with heater mounting holes 18, and the heating wires of the heater 6 pass through the heater mounting holes 18 and are positioned inside the liquid storage tank 1. The heater 6 and the air inlet pipe 2 are respectively connected on two opposite side walls of the liquid storage tank 1.
In order to ensure the sealing performance between the liquid storage tank 1 and the heater 6, the heater mounting hole 18 is provided with a sealing rubber ring which is clamped between the liquid storage tank 1 and the heater 6.
