[0027] The utility model provides a technical solution:

[0028] See also Figure 1 and Figure 2 A hydrogen furnace structure in this embodiment includes a hydrogen furnace body 100 and a tail gas treatment mechanism, the tail gas treatment mechanism includes a treatment tank 110, a treatment chamber 200 is provided in the treatment tank 110, a dilute sulfuric acid solution is provided in the treatment chamber 200 for treating the tail gas generated by the hydrogen furnace body 100, a tail gas inlet pipe 120 is provided in the treatment chamber 200, one end of which extends below the liquid surface of the dilute sulfuric acid solution, a wind duct 310 is provided at the other end of the tail gas inlet pipe 120, the wind duct 310 is connected to the hydrogen furnace body 100, and a blast component is provided in the wind duct 310 for promoting the tail gas to flow into the treatment tank 110.

[0029] In this embodiment, the hydrogen furnace body 100 adopts the structure in the prior art, and is used to burn a mixture of hydrogen and oxygen to generate heat. However, the tail gas generated after the combustion of hydrogen and oxygen carries high-temperature water vapor and unburned hydrogen and oxygen. If it is directly discharged into the air, it will cause the surrounding environment to be hot and humid, making people feel uncomfortable. Therefore, the tail gas needs to be treated;

[0030] The treatment tank 110 is used to contain the dilute sulfuric acid solution so that it can treat the tail gas generated when the hydrogen furnace body 100 is burned;

[0031] Among them, one end of the tail gas inlet pipe 120 is extended into the treatment chamber 200 below the liquid level of the dilute sulfuric acid solution, so that the tail gas discharged into the treatment chamber 200 by the tail gas inlet pipe 120 will first pass through the dilute sulfuric acid solution, so that the water vapor in the tail gas is absorbed, and there will be no water vapor in the discharged tail gas, causing the surrounding environment to be hot and humid; wherein, the top wall of the treatment tank 110 is provided with a tail gas exhaust pipe 111 for discharging the treated tail gas, which can be connected to the collection tank in actual use to collect the treated tail gas, so as to facilitate the reuse of the unburned hydrogen and oxygen therein, and avoid the waste of hydrogen and oxygen;

[0032] Compared with the prior art, in this embodiment, the exhaust gas treatment mechanism can absorb water vapor in the exhaust gas, so that the exhaust gas does not contain water vapor, does not cause humidity and heat in the surrounding environment, and reduces the impact on operators;

[0033] Among them, by setting the blast assembly, the tail gas in the hydrogen furnace body 100 can flow, and can better enter the dilute sulfuric acid solution in the processing chamber 200 through the tail gas inlet pipe 120, so that the tail gas can be processed;

[0034] The diameter of the air duct 310 gradually decreases from the hydrogen furnace body 100 to the treatment tank 110. This arrangement allows the air blast assembly to be installed at a location where the diameter of the air duct 310 is larger. At the same time, after the air blast assembly is started, the air flow velocity at a location where the diameter of the air duct 310 is smaller is accelerated, making it easier for the exhaust gas to enter the exhaust gas intake pipe 120.

[0035] When it is actually used, the end with a larger diameter of the air guide pipe 310 is connected to the tail gas discharge pipe of the hydrogen furnace body 100 through a flange.

[0036] Combination Figure 1 and Figure 3 As shown, in this embodiment, an arc-shaped cover 300 is provided at one end of the exhaust gas intake pipe 120, and a plurality of exhaust holes 301 for exhausting the exhaust gas are arranged on the arc-shaped cover 300.

[0037] In this embodiment, the arc cover 300 is in a truncated cone shape, and its diameter gradually increases from top to bottom. Through the arrangement of the arc cover 300 and the exhaust holes 301, the exhaust gas is discharged from the exhaust holes 301. The exhaust holes 301 at different positions are dispersed to allow the exhaust gas to fully contact the dilute sulfuric acid solution, so that the water vapor in the exhaust gas can be fully absorbed by the dilute sulfuric acid solution.

[0038] Combination Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the side wall of the processing tank 110 is provided with an arc groove 500 that matches the exhaust gas intake pipe 120, and the side wall of the processing chamber 200 is circumferentially provided with a step ring 201 that matches the bottom wall of the arc cover 300.

[0039] In actual use of this embodiment, the upper end of the processing chamber 200 is open, and a tank cover for sealing the same is provided at the opening. The arc groove 500 is arranged along the height direction of the processing tank 110 and opens upward. Through the arrangement of the arc groove 500 and the step ring 201, the exhaust gas intake pipe 120 and the arc cover 300 are extended into the processing chamber 200 through the opening, and the bottom end of the arc cover 300 is overlapped on the top end of the step ring 201, so that the two can be installed in the processing chamber 200.

[0040] In this embodiment, in order to prevent exhaust gas from leaking from the arc-shaped groove, a baffle 501 is slidably installed in the arc-shaped groove and is used to overlap the exhaust gas intake pipe 120 to block the arc-shaped groove 500;

[0041] Combination Figure 1 and Figure 4As shown, in this embodiment, the blowing assembly includes a mounting ring 401 threadedly connected to the inner wall of the air guide 310, and a mounting bracket 400 is provided inside the mounting ring 401. A rotatable rotating rod 420 is provided inside the mounting bracket 400, and a fan blade 421 for promoting the exhaust gas to flow into the treatment tank 110 is provided at one end of the rotating rod 420 close to the treatment tank 110, and a driving assembly for driving the rotating rod 420 to rotate is provided outside the exhaust gas intake pipe 120.

[0042] In this embodiment, the inner wall of the air duct 310 is provided with an internal thread matched with the mounting ring 401, and the outer wall of the mounting ring 401 is provided with an external thread matched with the internal thread, so as to realize the threaded installation of the mounting ring 401; wherein, the mounting bracket 400 is fixedly connected to the inside of the mounting ring 401 by welding, and through such a setting, when installing the mounting ring 401 in the air duct 310, it is only necessary to rotate the mounting bracket 400 to realize the installation, which is relatively simple and convenient;

[0043] The rotating rod 420 is arranged to penetrate the mounting bracket 400, and a bearing for mounting the rotating rod 420 is arranged inside the mounting bracket 400. Through this arrangement, the rotating rod 420 is arranged to rotate on the mounting bracket 400;

[0044] Among them, one end of the rotating rod 420 close to the processing tank 110 is fixedly connected to the fan blade 421. Through this arrangement, when the rotating rod 420 rotates, it can drive the fan blade 421 to rotate, thereby promoting the tail gas to flow from the hydrogen furnace body 100 into the processing chamber 200.

[0045] Combination Figure 1 and Figure 4 As shown, in this embodiment, a first bevel gear 422 is provided at one end of the rotating rod 420 away from the processing tank 110, and the driving assembly includes a motor 430 arranged on the outer wall of the air duct 310, and the output shaft 432 of the motor 430 extends into the air duct 310, and a second bevel gear 433 is provided on the output shaft 432 of the motor 430, and the second bevel gear 433 is meshed with the first bevel gear 422.

[0046] In this embodiment, the air guide tube 310 is provided with a mounting hole 410 through which the output shaft 432 of the motor 430 can pass;

[0047] The second bevel gear 433 is installed after the output shaft 432 of the motor 430 extends into the mounting hole 410, and the second bevel gear 433 and the output shaft 432 are fixedly connected by welding;

[0048] Among them, through the meshing setting of the first bevel gear 422 and the second bevel gear 433, when the first bevel gear 422 rotates, it can drive the second bevel gear 433 to rotate, and then drive the fan blade 421 to rotate; in actual use, the motor 430 is installed on the outer wall of the air duct 310 through the motor bracket 431.

[0049] Working principle: The starting motor 430 drives the fan blade 421 to rotate, so that the exhaust gas is introduced into the dilute sulfuric acid solution in the processing chamber 200 through the air duct 310 and the exhaust gas inlet pipe 120, and is discharged through the exhaust hole 301 on the arc cover 300, so that the water vapor in the exhaust gas is absorbed by the dilute sulfuric acid solution. The treated exhaust gas is discharged from the exhaust gas exhaust pipe 111 and enters the collection tank, which is convenient for the reuse of the exhaust gas and avoids waste.
