Description

Technical Field

[0001] This utility model relates to the field of ammonia spraying grid technology, and in particular to an ammonia spraying grid installation structure. Background Technology

[0002] Ammonia injection grilles typically consist of a main pipe, branch pipes, and nozzles. The main pipe is the primary pipeline for transporting ammonia gas, connecting to the ammonia supply source. Branch pipes branch off from the main pipe, and their number and spacing are designed according to the size of the flue and the required ammonia injection effect. They are generally evenly distributed across the cross-section of the flue. Nozzles are installed at the ends of the branch pipes, enabling ammonia gas to be injected into the flue at a certain angle and speed.

[0003] The disassembly and installation process of the branch pipes of the existing ammonia injection grille is quite complicated. It requires first sliding the entire grille out of the flue gas duct, and then disassembling the required branch pipes one by one. When maintenance personnel only need to maintain some branch pipes, the above operation is not only time-consuming and labor-intensive, but also increases the time and labor costs of maintaining or replacing branch pipes. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing an ammonia spraying grid installation structure that enables both unified assembly and disassembly of multiple branch pipes, as well as rapid assembly and disassembly of a single branch pipe.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an ammonia injection grid installation structure, comprising:

[0006] The gas supply assembly is detachably mounted on one side wall of the flue. The gas supply assembly includes an inlet end located outside the flue and multiple outlet ends located inside the flue, which are used to direct the gas at the inlet end to one side of each outlet end.

[0007] Multiple ammonia injection pipes are respectively installed at the corresponding gas outlet of the gas supply assembly, and can move towards or away from the gas supply assembly.

[0008] The slide rail assembly is slidably installed inside the flue pipe and is detachably connected to each ammonia injection pipe. When the slide rail assembly is connected to each ammonia injection pipe, it can drive each ammonia injection pipe to move closer to or further away from the gas supply assembly.

[0009] The end cap is detachably installed on the side wall of the flue pipe relative to the gas supply component. When the end cap is connected to the flue pipe, both ends of each ammonia injection pipe abut against the gas outlet end of the flue pipe and the end cap, respectively. The flue pipe is provided with an inspection hole for the installation of the end cap. The slide rail assembly and each ammonia injection pipe can slide out of the flue pipe through the inspection hole.

[0010] Furthermore, the outlet end of the gas supply component is truncated cone-shaped, and the ammonia injection pipe is provided with a groove that matches the outlet end. A sealing component is provided in the groove, which is used to seal the connection between the ammonia injection pipe and the outlet end of the corresponding gas supply component.

[0011] Furthermore, the slide rail assembly includes a slide platform slidably disposed within the flue pipe, and a slide rail provided within the flue pipe to guide the slide platform to slide towards or away from the gas supply component. The slide rail assembly also includes multiple T-shaped strips disposed at the bottom of each ammonia injection pipe. A first groove is provided on the side of the slide platform away from the gas supply component for the T-shaped strips to slide into. A blocking component is also provided on the slide platform to prevent the T-shaped strips from sliding out of the first groove.

[0012] Furthermore, the blocking component includes a baffle that is slidably disposed within the slide table and used to cut off the first slide groove. The sliding direction of the baffle is perpendicular to the sliding direction of the ammonia injection pipe. A second slide groove is provided in the slide table for the baffle to slide. The blocking component also includes a compression spring disposed in the second slide groove. One end of the compression spring is connected to the slide table, and the other end is connected to the baffle. When the compression spring is in its natural state, the baffle is located within the movement area of ​​the T-shaped strip. A through hole is provided on the baffle for the T-shaped strip to pass through. When the through hole is aligned with the first slide groove, the compression spring is in a compressed state.

[0013] Furthermore, the slide is equipped with multiple lifting rings that can be detachably connected to the hook.

[0014] The beneficial effects of this utility model are reflected in:

[0015] This invention, by opening an inspection hole in the flue pipe, allows the ammonia injection pipe to move away from the gas supply component and pass through the inspection hole after the end cap is removed from the inspection hole. This enables maintenance personnel to remove the required ammonia injection pipe for maintenance as needed. Furthermore, by setting a slide rail assembly that can be detachably connected to each ammonia injection pipe, maintenance personnel can connect the ammonia injection pipe to the slide rail assembly and then pull the slide rail assembly out of the inspection hole when overall maintenance is required, thus achieving the purpose of removing multiple ammonia injection pipes at the same time.

[0025] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-7 This utility model discloses an ammonia injection grid installation structure, comprising:

[0027] The gas supply assembly 1 is detachably mounted on one side wall of the flue pipe 5. The gas supply assembly 1 includes an inlet end located outside the flue pipe 5 and multiple outlet ends located inside the flue pipe 5, which are used to allow gas at the inlet end to flow to one side of each outlet end.

[0028] Multiple ammonia injection pipes 2 are respectively installed at the corresponding gas outlet of the gas supply component 1, and can move towards or away from the gas supply component 1.

[0029] The slide rail assembly 3 is slidably installed inside the flue pipe 5 and is detachably connected to each ammonia injection pipe 2. When the slide rail assembly 3 is connected to each ammonia injection pipe 2, it can drive each ammonia injection pipe 2 to move closer to or further away from the gas supply assembly 1.

[0030] The end cap 4 is detachably installed on the side wall of the flue pipe 5 relative to the gas supply component 1. When the end cap 4 is connected to the flue pipe 5, both ends of each ammonia injection pipe 2 abut against the gas outlet end of the flue pipe 5 and the end cap 4 respectively. The flue pipe 5 is provided with an inspection hole for the installation of the end cap 4. The slide rail assembly 3 and each ammonia injection pipe 2 can slide out of the flue pipe 5 through the inspection hole.

[0031] This invention, by opening an inspection hole in the flue pipe 5, allows the ammonia injection pipe 2 to move away from the gas supply component 1 and pass through the inspection hole after the end cap 4 is removed from the inspection hole. This enables maintenance personnel to remove the required ammonia injection pipe 2 for maintenance as needed. By setting a slide rail assembly 3 that is detachably connected to each ammonia injection pipe 2, maintenance personnel can connect the ammonia injection pipe 2 to the slide rail assembly 3 and then pull the slide rail assembly 3 out of the inspection hole when overall maintenance is required, thus achieving the purpose of removing multiple ammonia injection pipes 2 at the same time. When installing the ammonia injection pipe 2, simply push the ammonia injection pipe 2 close to the gas outlet end of the gas supply component 1, then install the end cap 4 at the inspection hole, and use the inspection hole to apply a pushing force to the ammonia injection pipe 2 so that the ammonia injection pipe 2 is tightly abutted against the gas outlet end of the gas supply component 1 to complete the installation.

[0032] In one embodiment, the outlet end of the gas supply component 1 is truncated cone-shaped, and the ammonia injection pipe 2 is provided with a settling groove adapted to the outlet end, and a sealing component is provided in the settling groove. The sealing component is used to seal the connection between the ammonia injection pipe 2 and the outlet end of the corresponding gas supply component 1 after they come into contact.

[0033] This design allows the ammonia injection pipe 2 to be nested within the outlet end of the gas supply assembly 1 after installation. This not only increases the sealing area between the ammonia injection pipe 2 and the outlet end, facilitating sealing by the sealing components, but also provides support to the corresponding end of the ammonia injection pipe 2 through the outlet end of the gas supply assembly 1, ensuring the installation stability of the ammonia injection pipe 2.

[0034] It should be noted that the sealing components and the air supply assembly 1 are common knowledge in the field, so their specific structural composition and working principle will not be described in detail here.

[0035] In one embodiment, the slide rail assembly 3 includes a slide platform 31 slidably disposed in the flue pipe 5. The flue pipe 5 is provided with a slide rail to guide the slide platform 31 to slide towards or away from the gas supply assembly 1. The slide rail assembly 3 also includes a plurality of T-shaped strips 32 disposed at the bottom of each ammonia injection pipe 2. The slide platform 31 is provided with a first groove on the side away from the gas supply assembly 1 for the T-shaped strips 32 to slide into. The slide platform 31 is also provided with a blocking component to prevent the T-shaped strips 32 from sliding out of the first groove.

[0036] This design allows the ammonia injection pipe 2 to slide on the slide table 31 via the T-shaped strip 32. Restricted by the T-shaped strip 32, it can only move along the first slide groove. By preventing the T-shaped strip 32 from sliding out of the first slide groove through the blocking component, it is ensured that when the slide table 31 slides towards or away from the gas supply component 1, it can move all the ammonia injection pipes 2 installed on it together. Thus, by simply changing the blocking state of the blocking component, the method of picking up and putting down the ammonia injection pipe 2 can be switched. Moreover, when the slide table 31 is inside the flue pipe 5, it can provide support for the ammonia injection pipe 2, further ensuring the installation stability of the ammonia injection pipe 2.

[0037] In one embodiment, the blocking component includes a baffle 33 slidably disposed within the slide table 31 and used to cut off the first slide groove. The sliding direction of the baffle 33 is perpendicular to the sliding direction of the ammonia injection pipe 2. A second slide groove is provided in the slide table 31 for the baffle 33 to slide. The blocking component also includes a compression spring 34 disposed in the second slide groove. One end of the compression spring 34 is connected to the slide table 31, and the other end is connected to the baffle 33. When the compression spring 34 is in its natural state, the baffle 33 is located within the moving area of ​​the T-shaped strip 32. A through hole is provided on the baffle 33 for the T-shaped strip 32 to pass through. When the through hole is aligned with the first slide groove, the compression spring 34 is in a compressed state.

[0038] This design allows the baffle 33 to isolate the first slide groove in its natural state, preventing the T-shaped strip 32, which is already in the first slide groove, from moving out. When maintenance personnel need to inspect a single ammonia injection pipe 2, they only need to push the baffle 33 to make the perforation align with the first slide groove, and then move the required ammonia injection pipe 2.

[0039] In practice, to facilitate the operator's sliding of the baffle 33, multiple handles for pushing the baffle 33 to move are provided on the baffle 33.

[0040] In one embodiment, the slide 31 is provided with a plurality of lifting rings that can be detachably connected to the hook.

[0041] This design allows the slide table 31 to be hoisted using a crane when it is moved into or out of the flue pipe 5, ensuring the smooth movement of the slide table 31.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] Additionally, "multiple" refers to two or more.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
