Description

[Technical field]

[0001] The invention relates to the field of chemical machinery, and in particular to a liquid distributor. [Background technology]

[0002] A reaction vessel is a container used to complete physical and chemical reactions of a medium. In industrial production, especially in the chemical, pharmaceutical, fertilizer, and refining industries, reaction vessels are used extensively as a pressure-bearing equipment due to process needs.

[0003] The liquid distributor is a commonly used internal part in the reaction vessel. Its function is to distribute the liquid in the reaction vessel. Please refer to Chinese Patent No. 201920969395.4, which discloses a liquid distributor for deep denitrification liquid-solid denitrification fluidized bed, including a plurality of concentrically arranged water ring pipes and a plurality of liquid distribution pipes radially connected to the water ring pipes. The water ring pipes and the liquid distribution pipes are located on the same horizontal plane. The liquid distribution pipes are radially arranged. A plurality of uniformly distributed one-way nozzles are vertically arranged on the water ring pipes. The one-way nozzles are used for one-way injection of the liquid in the water ring pipes. The defect of this liquid distributor is that because the one-way nozzle is directly arranged on the water ring pipe, it is limited by the structure of the water ring pipe, and the height and angle at which the liquid in the water ring pipe can be injected are relatively fixed.

[0004] Therefore, it is necessary to provide a liquid distributor that solves the above-mentioned technical problems. [Summary of the invention]

[Specific implementation method]

[0020] The liquid distributor of the present invention is further described in detail below through specific embodiments.

[0021] Ginseng Figures 1 to 5 As shown, a liquid distributor comprises: an upper distribution ring tube 1, a lower distribution ring tube 2 and nine groups of distribution core tube assemblies 3, three evenly arranged first connecting members 40 and three evenly arranged second connecting members 41 are welded on the inner wall of the cylinder 4, the upper distribution ring tube 1 is respectively installed on the three first connecting members 40 through three first fixing members 5, and the lower distribution ring tube 2 is respectively installed on the three second connecting members 41 through three second fixing members 6. In this embodiment, the first fixing members 5 and the second fixing members 6 are U-shaped bolts and nuts.

[0022] The upper distribution ring tube 1 is connected to the liquid inlet pipe 7, and the lower distribution ring tube 2 is connected to the compressed air inlet pipe 8. The lower distribution ring tube 2 includes an inner ring tube 20, an outer ring tube 21 and a radial tube 22 for connecting the inner ring tube 20 and the outer ring tube 21. The upper distribution ring tube 1, the inner ring tube 20 of the lower distribution ring tube 2, and the outer ring tube 21 of the lower distribution ring tube 2 are concentrically arranged, and after the above three ring tubes are projected onto a projection plane perpendicular to the axis, the upper distribution ring tube 1 is located between the inner ring tube 20 of the lower distribution ring tube 2 and the outer ring tube 21 of the lower distribution ring tube 2. The advantage of such an arrangement is that it not only saves the installation space of the liquid distribution pipe in the cylinder, but also ensures that there is enough compressed air to spray the liquid.

[0023] The upper distribution ring tube 1 is provided with nine liquid outlet holes 10, the inner ring tube 20 of the lower distribution ring tube 2 is provided with three evenly distributed compressed air outlet holes 200, and the outer ring tube 21 of the lower distribution ring tube 2 is provided with six evenly distributed compressed air outlet holes 210. The branch core tube assembly 3 includes six outer ring branch core tube assemblies 30 and three inner ring branch core tube assemblies 31. The six outer ring branch core tube assemblies 30 are respectively used to connect the six compressed air outlet holes 210 on the outer ring tube 21 of the lower distribution ring tube 2 and six of the liquid outlet holes 10 on the upper distribution ring tube 1, and the three inner ring branch core tube assemblies 31 are respectively used to connect the three compressed air outlet holes 200 on the inner ring tube 20 of the lower distribution ring tube 2 and three of the liquid outlet holes 10 on the upper distribution ring tube 1. Each group of branch core tube components 3 includes a first branch core tube 32 connected to the liquid outlet hole 10 and a second branch core tube 33 connected to the compressed air outlet holes 200 and 210. The free end of the first branch core tube 32 merges with the free end of the second branch core tube 33 so that the compressed air in the second branch core tube 33 sprays out the liquid in the first branch core tube 32. In this embodiment, the first branch core tube 32 is set in an inverted L shape, and the second branch core tube 33 is set in a straight tube shape. Of course, in other embodiments, the first branch core tube 32 is set in a straight tube shape and the second branch core tube 33 is set in an inverted L shape, which can also realize the present invention, or the first branch core tube 32 and the second branch core tube 33 are both set in an inverted L shape, which can also realize the present invention.

[0024] The working principle of the liquid distributor in the present invention is as follows: the pressurized liquid enters the upper distribution ring tube 1 through the liquid inlet pipe 7, and then enters the first branch core tube 32 of the branch core tube assembly 3 through the nine liquid outlet holes 10 on the upper distribution ring tube 1; the compressed air enters the lower distribution ring tube 2 through the compressed air inlet pipe 8, and then enters the second branch core tube 33 of the branch core tube assembly 3 through the nine compressed air outlet holes 200 and 210 on the lower distribution ring tube 2; since the free end of the second branch core tube 33 merges with the free end of the first branch core tube 32, the compressed air in the second branch core tube 33 blows the liquid in the first branch core tube 32 into the cylinder 4 to react with the steam in the cylinder 4.

[0025] To summarize, compared with the liquid distributor structure in the prior art, the liquid distributor in the present invention allows the injection height and injection position of the liquid to be adjusted according to specific working conditions. In addition, the present invention designs the lower distribution ring pipe as a double-ring pipe structure, designs the upper distribution ring pipe as a single-ring pipe structure, and locates the upper distribution ring pipe between the inner ring pipe and the outer ring pipe of the lower distribution ring pipe. Such an arrangement structure greatly saves installation space and ensures that there is enough compressed air in the second branch core pipe to spray the liquid.

[0026] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
