[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Please also read Figures 1 to 4 The gas distributor provided by the utility model is now described. The gas distributor comprises a cylinder 2 and a liquid distributor 1, a gas-liquid reaction unit, a gas distribution unit and an air intake unit arranged in the cylinder 2 from top to bottom; the gas distribution unit comprises an inverted conical baffle 13 and a gas distribution plate 6; the inverted conical baffle 13 is provided with an air intake hole connected to the air intake unit, the gas distribution plate 6 is located above the inverted conical baffle 13, and is an inverted cone coaxial with the inverted conical baffle 13, and a plurality of air vents 5 are evenly arranged on the gas distribution plate 6; the edge of the gas distribution plate 6 and the edge of the inverted conical baffle 13 are sealed by an annular plate 12.

[0027] The gas-liquid reaction unit includes a liquid distribution plate 10, an upper air pipe 4 connected to the liquid distribution plate 10, and a conical cylinder cap 3 arranged on the top of the upper air pipe 4; the liquid distribution plate 10 is a right cone; the edge of the liquid distribution plate 10 is connected to the edge of the gas distribution plate 6 to form a gas sealing cavity, and the lower end of the upper air pipe 4 is connected to the gas sealing cavity; a gap is left between the liquid distribution plate 10 and the inner wall of the cylinder 2 for liquid to flow downward.

[0028] The utility model provides a gas distributor. When the gas enters the gas distribution unit, due to the existence of the sealing cone surface of the gas distribution plate 6, the gas is diverted to the direction of the cone busbar, and then flows upward evenly through the circular vents 5 of the gas distribution plate 6 to reach the liquid distribution plate 10, and then reaches the cone cap 3 through the upper air pipe 4. The gas overflows along the air outlet above the upper air pipe 4, flows upward along the cone cap 3, and fully contacts and reacts with the liquid from the liquid distributor 1. The reacted liquid flows downward to the liquid distribution plate 10, and the reaction liquid flows along the cone cap 3 to the liquid guide groove 11. The liquid guide groove 11 is used to guide the gas to the edge of the liquid distribution plate 10, and the gas flows to the bottom of the cylinder 2 through the gap between the liquid distribution plate 10 and the inner wall of the cylinder 2, thereby completing the gas intake, distribution, reaction, liquid guide, and operation, and achieving full absorption of the gas.

[0029] The gas distributor provided by the utility model distributes the gas through the inverted cone-shaped gas distribution plate 6 and exhausts the gas through the upper air pipe 4 to the gas-liquid reaction area above the liquid distribution plate 10, which can effectively solve the problem of uneven gas distribution and improve the effect and reaction efficiency of material reaction; and the cone cap 3 above the upper air pipe 4 covers the upper part of the upper air pipe 4, which can prevent the material from entering the upper air pipe 4 to block the gas distributor, and avoid the problem of uneven gas distribution caused by the material blocking the gas distribution unit, resulting in the problem that the material reaction effect cannot be guaranteed, thereby also ensuring the effect and reaction efficiency of the material reaction.

[0030] The included angles between the generatrix of the inverted cone and the right cone of the present application and the horizontal plane are maintained at 45°-60°.

[0031] In some embodiments, see Figures 1 to 3 As shown, the gas distribution unit further includes a plurality of gas guide plates 14, which are radially embedded between the inverted conical baffle plate 13 and the gas distribution plate 6 along the generatrix of the inverted conical baffle plate 13; the vent hole 5 is located between two adjacent gas guide plates 14. When the gas enters the gas distribution unit, it is diverted to the direction of the generatrix of the conical surface due to the existence of the sealing cone surface of the gas distribution plate 6, and then is evenly divided into several flows through the gas guide plate 14, and flows evenly upward through the circular vent holes 5 of the gas distribution plate 6, thereby ensuring the uniformity of gas distribution.

[0032] Optionally, the gas guide plate 14 is welded to the inverted conical baffle 13 , and the gas distribution plate 6 is welded to the gas guide plate 14 .

[0033] In some embodiments, see Figure 3 The diameters of the vent holes 5 arranged along the generatrix of the inverted conical baffle 13 decrease from top to bottom.

[0034] In some embodiments, see Figure 4 The liquid distribution plate 10 is evenly distributed with liquid guide grooves 11 extending radially along its generatrix direction. The upper gas pipe 4 is fixed on the partition between two adjacent liquid guide grooves 11. The width of the liquid guide groove 11 gradually increases from top to bottom along the generatrix direction of the liquid distribution plate 10. The diameter of the upper gas pipe 4 gradually increases from the top of the liquid distribution plate 10 along its generatrix direction. The reaction liquid from the liquid distributor 1 enters the liquid guide groove 11 along the cone cap 3 after contacting with the gas, and then flows to the bottom of the cylinder 2 along the gap between the liquid distribution plate 10 and the inner wall of the cylinder 2.

[0035] Optionally, the cross section of the liquid guide groove 11 along the circumferential direction is a trapezoidal shape or a rectangular shape. The reaction liquid flows radially downward along the liquid guide groove 11, and flows downward from the gap between the liquid distribution plate 10 and the cylinder 2 to the bottom of the cylinder 2. Since the gas sealing cavity is sealed, the liquid will not enter the gas sealing cavity, and the clogging of the gas distribution unit by the material is also avoided.

[0036] Optionally, the upper air pipe 4 is welded to the partition of the liquid guiding groove 11 .

[0037] In some embodiments, see Figure 1 , the distance between the top of the upper air pipe 4 and the cone cap 3 above is 3-5mm. A cone cap 3 is provided on the top of the upper air pipe 4 to block the liquid. The vertical distance between the cone cap 3 and the upper air port 9 on the top of the upper air pipe 4 is set to 3-5mm, which can not only ensure that the gas can overflow more in the horizontal direction, but also avoid liquid splashing and affecting the use of the gas distributor. The gas is transported to the upper air port 9 through the upper air pipe 4, and is blocked by the cone cap 3. The gas overflows from the upper air port 9 and contacts with the reaction liquid from the liquid distributor 1. The reaction liquid falls on the cone cap 3 and flows along the oblique edge to the center line of the liquid guide groove 11, and flows downward from the liquid distribution plate 10 through the gap between the liquid distribution plate 10 and the cylinder 2.

[0038] In some embodiments, see Figure 1 , the top of the upper gas pipe 4 is provided with continuous tooth-shaped upper gas ports 9 along its circumferential direction. When the gas enters the gas distribution unit, due to the existence of the sealing cone surface of the gas distribution plate 6, it is diverted to the direction of the cone surface generatrix, and then evenly divided into several flows through the gas guide plate 14, flows evenly upward through the circular vents 5 of the gas distribution plate 6, reaches the liquid distribution plate 10, and then reaches the position of the cone cap 3 through the upper gas pipe 4. The gas overflows along the tooth-shaped upper gas port 9 above the upper gas pipe 4, flows upward along the cone cap 3, and fully contacts with the liquid from the liquid distributor 1; the gas can continue to be transported upward through the upper gas port 9, further diverting the gas, greatly increasing the contact area between the gas and the reaction liquid, and thus improving the reaction efficiency of the gas-liquid reaction.

[0039] In some embodiments, see Figure 1 The edge of the liquid distribution plate 10 exceeds the edge of the gas distribution plate 6 by a width of 1.0-1.5 cm. The annular plate 12 extends upward to connect with the liquid distribution plate 10 to form a seal of the gas sealing cavity; preferably, a sealing ring is provided between the annular plate 12 and the liquid distribution plate 10 to improve the sealing effect.

[0040] In some embodiments, see Figure 1 The gap between the edge of the liquid distribution plate 10 and the inner wall of the cylinder 2 is 3-5 mm, so that the reaction liquid can flow downward to the bottom of the cylinder 2.

[0041] In some embodiments, see Figure 1 The air intake unit includes an air intake pipe 8 extending from the outside into the cylinder 2, a collecting bin 15 connected to the upper end of the air intake pipe 8, and a connecting pipe 7 connected between the collecting bin 15 and the inverted conical baffle 13; an air intake baffle 16 is arranged in the collecting bin 15, and the air intake baffle 16 is arranged obliquely above the air intake pipe 8. The gas enters the collecting bin 15 through the air intake pipe 8, and enters the gas distribution unit through the connecting pipe 7. The baffle at the connection between the collecting bin 15 and the air intake pipe can block the material falling from the top during the air intake process, thereby avoiding the problem of uneven gas distribution caused by the material blocking the air intake pipe and the gas distribution unit. The collecting bin 15 can collect the material falling from the top into the collecting bin 15 under the action of the gas baffle.

[0042] Optionally, the air intake pipe, the collecting bin 15 and the air intake baffle 16 are connected by welding, and the connecting pipe 7, the collecting bin 15 and the inverted conical baffle 13 are also connected by welding.

[0043] The gas enters the gas distribution unit through the air inlet pipe 8. Due to the blocking effect of the conical surface of the gas distribution plate 6, the gas enters the gap between the inverted conical baffle 13 and the gas distribution plate 6, and is diverted by the embedded gas guide plate 14, enters the surface of the gas distribution plate 6, and transports the gas to the gas-liquid reaction unit through the circular air vents 5, which can fully divert and pressure the gas in the gas distribution unit, thereby improving the uniformity of gas distribution.

[0044] In some embodiments, see Figure 1 Two intake baffles 16 inclined in different directions are arranged above the intake pipe 8, and an intake gap is left between the two intake baffles 16; the upper end of one of the intake baffles 16 extends above the other intake baffle 16. The vertical distance between the lower intake baffle 16 and the upper intake baffle 16 is 1-2 mm, that is, the width of the intake gap, which can prevent the material from entering the intake pipe and blocking the intake pipe, and can also ensure that the gas enters the gas distribution unit from the intake gap.

[0045] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
