Because the flow guide plate 06 is obliquely arranged on the rotating rod 05 and rotates towards the direction opposite to the self-oblique direction, when the flow guide plate 06 rotates, the rotation of the flow guide plate 06 can stir the airflow in the direction vertical to the axis of the rotating rod 05, thereby promoting the flow of the airflow, compared with the prior art, the reaction is directly carried out after the reaction gas is simply introduced into the reaction kettle 01, because the concentration of each gas introduced into the reaction kettle 01 is higher and the molecular mass of each gas is different, the gases are gathered together again after being filled into the reaction kettle 01, the carbon dioxide with large molecular mass is at the lowest part, the minimum water vapor is at the highest part, ethane is in the middle part, thereby forming the layering phenomenon, when the reaction is carried out, each gas is required to participate in the reaction and is carried out under the catalytic action of the catalyst, the layering phenomenon not only affects the reaction between gases, but also can not enable the gases to be fully contacted with the catalyst, so that the reaction process is slow, and in addition, the catalyst is generally directly placed in the tank body of the reaction kettle when in use, and the full contact of the gases and the catalyst can be avoided, so that the reaction is not facilitated; according to the technology, the drainage plate 06 is obliquely arranged, so that air flows can be mixed in the direction perpendicular to the axis of the rotating rod 05, and can flow to the upper end along the lower end of the drainage plate 06, and therefore, when the drainage plate 06 continuously rotates along with the rotating rod 05, the air in the reaction kettle 01 can continuously flow from the lower part to the upper part, the air flow in the reaction kettle 01 is promoted, and the reaction between the air is facilitated; because a plurality of air inlets 12 are arranged, the air inlets 12 can be driven to rotate simultaneously when the flow guide plate 06 rotates, so that air flow can continuously flow into the air inlets 12 (in order to ensure that the air flow can continuously flow into the air inlets 12, it is required to ensure that the air inlets of the air inlets 12 are horizontal to the rotating direction), because a plurality of air inlets 12 are arranged, even when multilayer layering occurs during gas reaction in the reaction kettle 01, the air flow can flow into the flow guide plate 06, at least not less than one air flow is implemented, and the air flow is positioned at the upper end, the lower end and the middle position of the flow guide plate 06, the air flow of the upper, the middle and the lower layers can flow into the flow guide plate 06 through the air inlets 12, and then flow into the mixing cylinder 08 through the flow guide plate 06, so that the air flow can be more concentrated in the mixing cylinder 08 with smaller cross-sectional area, contact among the air flows can be promoted, thereby promoting reaction, and then pass through a catalyst, the reaction is promoted by the catalyst through the blowing port 26, so that the problems that the traditional device is not beneficial to contact of all gases with the catalyst due to layering and the catalyst can only be stacked in the tank body during arrangement are solved, and the reaction efficiency is higher; after the air current blows off through the mouth 26 of blowing, can blow off perpendicularly downwards to can contact the inner wall lower surface in the reation kettle 01, thereby can make the air current upwards bounce-back flow, can play cooperation drainage plate 06 makes the air current follow ascending flow down, thereby can play the effect that promotes all air currents and flow, thereby enable the more abundant contact of gaseous ability, thereby be favorable to the reaction to go on.
This technique can not only carry out circumferential direction's shearing action on the 05 axis direction of perpendicular bull stick through the setting drainage plate 06 of slope, gas that enables simultaneously in the reation kettle 01 flows along drainage plate 06 from the below, thereby make the phenomenon of gaseous disappearance layering, thereby be favorable to the reaction between the gas, simultaneously owing to be provided with in a plurality of air inlets 12 take reation kettle 01 air current into mixing drum 08, thereby can promote the contact between the gas, just blow off from the mouth 26 of blowing after the catalyst through setting up in mixing drum 08 afterwards, guarantee all gaseous contact that can both be abundant with the catalyst, thereby be favorable to going on of reaction, efficiency is higher.
As a further scheme of the invention, the shearing part comprises a second rotating shaft 23 which is connected to the inner part of the mixing barrel 08 in a limiting and rotating manner and is close to one end of the drainage plate 06, a shearing fan blade 25 blowing wind from the drainage plate 06 to the air blowing port 26 is arranged on the second rotating shaft 23, two flow limiting frames 24 are arranged on the inner wall of the mixing barrel 08 and positioned on two sides of the shearing fan blade 25, and the shearing part also comprises a transmission component capable of driving the first rotating shaft 15 to rotate.

When the shearing fan blades 25 rotate, the wind power generated by the shearing fan blades can promote airflow to flow into the air inlet 12, meanwhile, as the catalyst is arranged in the mixing cylinder 08, the flow per unit cross-sectional area is reduced when the airflow passes through the catalyst, the airflow can be slowed down, and the rotation of the shearing fan blades 25 can be favorable for the flow of the airflow, so that the airflow can be ensured to efficiently flow into the air inlet 12 and then blown out from the air blowing port 26, and the function of promoting the flow of the airflow can be achieved; in addition, when the air current is through shearing fan blade 25, shearing fan blade 25 is in the continuous rotation to can play the effect of shearing the air current, can constantly break up the air current, thereby make multiple reaction gas mix, thereby pass through the honeycomb air vent of catalyst afterwards again, thereby can guarantee that all gas can abundant mixing simultaneously with abundant contact of catalyst, thereby improved reaction efficiency and effect. The arranged flow limiting frame 24 can play a flow limiting function, and ensures that airflow cannot flow through the position where the shearing fan blade 25 is in contact with the inner wall of the mixing cylinder 08, and the airflow can be fully sheared by the shearing fan blade 25, so that the shearing effect of the shearing fan blade 25 is ensured. In addition, in order to further improve the shearing effect, a plurality of shearing blades 25 can be arranged on the second rotating shaft 23 at equal intervals to ensure that the airflow can be sufficiently sheared by the shearing blades 25.
