Description

Technical Field

[0001] This utility model relates to the technical field of gasifier accessories, and in particular to a uniformly distributed nozzle for a pure oxygen gasifier. Background Technology

[0002] Currently, the structure of nozzles or burners used in gasifiers is usually a multi-ring nozzle arranged coaxially. The nozzles of the outer ring pipe, inner ring pipe and central pipe are all tapered inward at a certain angle to facilitate the impact and mixing of the fluid after it is ejected from the nozzle. The main function of these nozzles is to inject materials (including fuel and gasifying agent) into the gasifier for gasification.

[0003] In the prior art, patent number CN206051961U provides a nozzle for a gasifier, with at least one channel coaxially arranged, wherein the outlet of the outermost channel has a first radially outward deflection angle. The purpose of this invention is to provide a nozzle for a gasifier that forms a layered protective layer on the inner wall of the gasifier's dome during operation.

[0004] While this technical solution can form a layered protective layer on the inner wall of the gasifier dome during use, the nozzle makes it difficult to fully mix the gaseous fuel and gasifying agent such as pure oxygen entering the gasifier, and also makes it difficult to uniformly distribute the gasifying agent and gaseous fuel, resulting in limited utilization of the gaseous fuel in the gasifier. Therefore, we propose a uniformly distributed nozzle for a pure oxygen gasifier. Summary of the Invention

[0005] The present invention mainly addresses the technical problems existing in the prior art by providing a uniformly distributed nozzle for a pure oxygen gasification furnace.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a uniformly distributed nozzle for a pure oxygenation furnace, comprising a channel pipe, a first annular pipe disposed on the outer side of the channel pipe, the interior of the first annular pipe being hollow, a mixing cone movably mounted on the bottom surface of the channel pipe, the mixing cone being a frustum shape narrower at the top and wider at the bottom, the bottom surface of the first annular pipe being fixedly connected to the mixing cone, the lower end of the first annular pipe being inclined and extending into the interior of the mixing cone and communicating with the mixing cone, a second annular pipe disposed on the outer side of the lower end of the first annular pipe, a third annular pipe disposed on the outer wall of the lower end of the second annular pipe, flanges for matching use being fixedly installed between the outer wall of the channel pipe and the upper end of the first annular pipe, the outer wall of the first annular pipe and the upper end of the second annular pipe, and the outer wall of the second annular pipe and the upper end of the third annular pipe, respectively, and an installation strip fixedly installed on the inner wall of the lower end of the mixing cone, the inner wall of the installation strip being provided with multiple sets of mixing components.

[0007] Preferably, the mixing assembly includes a connecting block fixedly connected to the mounting strip, a rotating rod rotatably mounted at the end of the connecting block, and multiple mixing plates fixedly mounted on the outer wall of the rotating rod.

[0013] This invention provides a uniformly distributed nozzle for a pure oxygen combustion furnace. It has the following beneficial effects:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4As shown, a uniformly distributed nozzle for a pure oxygenation furnace includes a channel pipe 1, a first annular pipe 2 disposed on the outer side of the channel pipe, the first annular pipe 2 being hollow inside, a mixing cone 9 movably mounted on the bottom surface of the channel pipe 1, the mixing cone 9 being a frustum shape narrower at the top and wider at the bottom, the bottom surface of the first annular pipe 2 being fixedly connected to the mixing cone 9, the lower end of the first annular pipe 2 being inclined and extending into the interior of the mixing cone 9 and communicating with the mixing cone 9, a second annular pipe 3 disposed on the outer side of the lower end of the first annular pipe 2, a third annular pipe 4 disposed on the outer wall of the lower end of the second annular pipe 3, flanges 5 for matching use being fixedly installed between the outer wall of the channel pipe 1 and the upper end of the first annular pipe 2, the outer wall of the first annular pipe 2 and the upper end of the second annular pipe 3, and the outer wall of the second annular pipe 3 and the upper end of the third annular pipe 4, and an installation strip 11 being fixedly installed on the inner wall of the lower end of the mixing cone 9, the inner wall of the installation strip 11 being provided with multiple sets of mixing components;

[0025] In use, the nozzle can be installed at the corresponding position on the gasifier via the flange 5 at the lower end of the third annular pipe 4. Each of the channel pipe 1, the first annular pipe 2, the second annular pipe 3, and the third annular pipe 4 is equipped with an inlet pipe connected to an external gas storage device. The channel pipe 1 and the first annular pipe 2, the first annular pipe 2 and the second annular pipe 3, and the second annular pipe 3 and the third annular pipe 4 are connected via flanges. The interiors of the channel pipe 1 and the second annular pipe 3 are used to transport pure oxygen, which is used as a gasifying agent in this device. The interior of the first annular pipe 2 is used to transport gaseous fuel, and the interior of the third annular pipe 4 is used to transport protective gas. The gaseous fuel in the first annular pipe 2 enters the mixing cone 9 at an angle. Simultaneously, the pure oxygen in the channel pipe 1 enters the mixing cone 9 and mixes thoroughly with the gaseous fuel in the first annular pipe 2. The pure oxygen in the second annular pipe 3 further mixes evenly with the gaseous fuel after entering the mixing cone 9. When the rotating rods 13 in the multiple mixing components rotate, the gaseous fuel and pure oxygen entering the gasifier through the mixing cone 9 are further mixed and evenly distributed.

[0026] like Figure 4 As shown, the mixing assembly includes a connecting block 12 fixedly connected to the mounting strip 11. A rotating rod 13 is rotatably mounted at the end of the connecting block 12. Multiple mixing plates 14 are fixedly mounted on the outer wall of the rotating rod 13. The rotation of the rotating rod 13 can drive the multiple mixing plates 14 to rotate, thereby accelerating the flow rate of the gas around the mixing assembly.

[0027] like Figure 3As shown, a heating module 16 is provided at the upper end of the mixing cone 9 between the channel tube 1 and the first annular tube 2. A heat-conducting medium is provided between the channel tube 1 and the first annular tube 2. The heating module 16 heats the heat-conducting medium filling the space between the channel tube 1 and the first annular tube 2, which can indirectly heat the walls of the channel tube 1 and the first annular tube 2, thereby increasing the temperature inside the channel tube 1 and the first annular tube 2, and also accelerating the movement speed of gas molecules in the channel tube 1 and the first annular tube 2.

[0028] like Figure 3 As shown, the lower end of the third annular tube 4 is inclined, and the gap width between the lower end of the third annular tube 4 and the mixing cone 9 is between one centimeter and two centimeters. A flange 5 is fixedly installed on the outer wall of the lower end of the third annular tube 4. After the protective gas in the third annular tube 4 is ejected outward, it can form an umbrella-shaped protective area under the guidance of the outer wall of the mixing cone 9.

[0029] like Figure 3 As shown, multiple reinforcing holes 10 are provided through the mixing cone 9 at positions corresponding to the end of the second annular tube 3, and a one-way valve is movably installed inside the mixing cone 9 at positions corresponding to the multiple reinforcing holes 10; the multiple reinforcing holes 10 are located below the lower end of the first annular tube 2, so the pure oxygen in the second annular tube 3 and the pure oxygen in the channel tube 1 are respectively distributed on the upper and lower sides of the gaseous fuel output from the first annular tube 2, which can make the gaseous fuel and pure oxygen fully mixed.

[0030] like Figure 2 and Figure 3 As shown, the outer wall of the first annular tube 2 is also provided with multiple connecting tubes 7. The number of connecting tubes 7 is the same as that of the mixing component. The lower end of the connecting tube 7 is fixedly connected to a guide tube 8. The end of the guide tube 8 is correspondingly set with the mixing component. The upper end of the second annular tube 3 is fixedly installed with an air pump 6 at the position corresponding to the connecting tube 7. After the air pump 6 is started, it introduces part of the pure oxygen into the mixing cone 9 through the connecting tube 7 and the guide tube 8. When the gas is ejected from the end of the inclined guide tube 8, it can push multiple mixing plates 14 to make the rotating rod 13 rotate continuously.

[0031] like Figure 4 As shown, a plurality of through holes 15 are provided through the mixing plate 14, and the plurality of through holes 15 are arranged in an array on the mixing plate 14; the plurality of arrayed through holes 15 facilitate gas flow between two adjacent mixing plates 14.

[0032] The working principle of this utility model is as follows: In use, the nozzle can be installed on the gasifier at the corresponding position through the flange 5 at the lower end of the third annular pipe 4. Each of the channel pipe 1, the first annular pipe 2, the second annular pipe 3, and the third annular pipe 4 is equipped with an inlet pipe connected to an external gas storage device. The interiors of the channel pipe 1 and the second annular pipe 3 are used to transport pure oxygen, which is used as a gasifying agent in this device. The interior of the first annular pipe 2 is used to transport gaseous fuel, and the interior of the third annular pipe 4 is used to transport protective gas. The gaseous fuel in the first annular pipe 2 enters the mixing cone 9 at an angle along the first annular pipe 2. Simultaneously, the pure oxygen in the channel pipe 1 enters the mixing cone 9 and mixes thoroughly with the gaseous fuel in the first annular pipe 2. During this process, the heating module 16 located between the channel pipe 1 and the first annular pipe 2 can heat the channel pipe through the heat-conducting medium filled between them. The walls of pipe 1 and the first annular pipe 2 are heated to enhance the gas movement speed in the channel pipe 1 and the first annular pipe 2. At the same time, some pure oxygen enters the mixing cone 9 through the second annular pipe 3. One-way valves are installed in the reinforcing holes 10 on the mixing cone 9 corresponding to the second annular pipe 3. After the pure oxygen in the second annular pipe 3 enters the mixing cone 9, it further mixes the pure oxygen with the gaseous fuel evenly. During the process of pure oxygen and gaseous fuel gathering, multiple sets of mixing components located at the lower end of the mixing cone 9 rotate. After the gas pump 6 is started, it introduces some pure oxygen into the mixing cone 9 through the connecting pipe 7 and the guide pipe 8. When the gas is ejected from the guide pipe 8, it can push multiple mixing plates 14 to make the rotating rod 13 rotate continuously. When the rotating rods 13 in the multiple sets of mixing components all rotate, the gaseous fuel and pure oxygen entering the gasifier through the mixing cone 9 can be further mixed and evenly distributed.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
