Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray tower technology, specifically to an insertable detachable structure and a spray tower. Background Technology
[0002] Various industries have developed numerous new safety production solutions from different perspectives, combining technological innovation, management optimization, and industry practices, especially for production operations that pose significant threats to human safety, such as those involving flammable, explosive, toxic, or harmful gases and high-altitude work.
[0003] The chemical industry commonly uses spray towers to treat production waste gas, such as ammonia stripping towers, ammonia stripping towers, and silane gas spray towers. These towers are relatively tall (generally 10-20m, depending on calculations), and the spray solution inside is usually strongly acidic or alkaline, placing high demands on the materials used for the tower body and internal components. To increase spray absorption efficiency, multiple nozzles are installed inside the tower, and multiple spray layers are configured. The following safety issues commonly arise when maintaining the nozzles in these towers:
[0004] 1. The tower is relatively tall, and due to the high corrosiveness of the spraying liquid and the effect of the spraying effect, there is no maintenance platform inside the tower. Therefore, the maintenance of the sprinkler heads inside the tower becomes a high-altitude operation after the machine is shut down, which is prone to high-altitude fall safety accidents.
[0005] 2. Due to the influence of gas composition and process, the exhaust gas in the tower is generally flammable, explosive and highly harmful to the human body, such as ammonia, hydrogen and hydrochloric acid, which can easily cause human poisoning and pose an explosion risk.
[0006] To address the above safety issues, this patent proposes an insertable detachable main pipe suitable for use with this type of tower. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide an insertable detachable structure and a spray tower, which allows the spray head to be pulled out of the tower for maintenance without people entering the tower body, making operation convenient and avoiding safety accidents.
[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0009] An insertable detachable structure includes: a spray pipe and a spray tower body. The spray pipe is provided with multiple spray nozzles arranged in rows in a detachable manner. The spray tower body is provided with at least one inlet pipe communicating with its inner cavity. A receiving pipe is coaxially provided on the inner wall of the spray tower body, directly opposite each inlet pipe. A bracket is provided inside the inlet pipe, allowing the spray pipe and spray nozzles to pass through and supporting the spray pipe. One end of the spray pipe and the spray nozzles on it enter the spray tower body through the inlet pipe and the bracket and are then inserted into the receiving pipe directly opposite the inlet pipe. The other end of the spray pipe is outside the inlet pipe and is connected to the inlet pipe by a flange.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the bracket includes two supports and two arc-shaped support plates. The two supports are fixed inside the inlet pipe, and each support is provided with an arc-shaped support plate. The side of the arc-shaped support plate facing the spray pipe is an arc-shaped surface adapted to the spray pipe. The two arc-shaped support plates are located on both sides of the spray pipe and support the spray pipe.
[0012] Furthermore, the curved surface of the arc-shaped support plate is provided with multiple ball bearings that rotate in a row along the length of the spray pipe and come into contact with the wall of the spray pipe.
[0013] Furthermore, the inlet end of the inlet pipe is provided with a first flange, and the end of the spray pipe outside the inlet pipe is fitted with a second flange that is seamlessly connected to it. The second flange and the first flange are connected by bolts.
[0014] Furthermore, a sealing gasket is provided between the first flange and the second flange.
[0015] Furthermore, the second flange has at least two handles on its outer side.
[0016] Furthermore, a third flange is provided at the end of the spray pipe outside the inlet pipe.
[0017] Furthermore, a sealing ring is installed inside the receiving pipe to fit onto the spray pipe.
[0018] Furthermore, the spray tower body has two inlet pipes connected to its inner cavity on the same radial cross section.
[0019] Based on the above technical solution, this utility model also provides a spray tower, including: the above-mentioned insertable detachable structure.
[0020] The beneficial effects of this utility model are as follows:
[0021] When maintenance of the sprinkler heads is required, first disconnect the spray pipe from the inlet pipe, then simultaneously pull the spray pipe and sprinkler heads out of the spray tower body, and then remove the sprinkler heads for maintenance; after maintenance, reinstall the sprinkler heads on the spray pipe, then reinsert one end of the spray pipe with the sprinkler heads into the spray tower body through the inlet pipe and bracket, and finally insert it into the receiving pipe directly opposite the inlet pipe, and reconnect the spray pipe and inlet pipe with flanges to complete the maintenance;
[0022] The entire maintenance process allows the nozzles to be pulled out of the tower for maintenance without personnel entering the tower body. The operation is simple and can be disassembled at will. Without increasing investment costs, it can effectively avoid the dangers of conventional maintenance, i.e., avoid safety accidents, and has obvious technical advantages. Since the spray pipes and nozzles have a certain weight and the spray pipes are also relatively long, the introduction of brackets can always support the spray pipes as a force point during the process of pulling out and re-inserting them. On the one hand, it can easily ensure that the insertion end of the spray pipe is aligned with the opening of the receiving pipe, so that the spray pipe can be quickly inserted into the receiving pipe. On the other hand, it can suspend the nozzles in the air to avoid damage to the nozzles, and at the same time reduce the labor intensity of the workers. Attached Figure Description

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0029] Example 1
[0030] like Figures 1-3As shown, an insertable detachable structure includes: a spray pipe 1 and a spray tower body 2. The spray pipe 1 is detachably equipped with multiple nozzles 3, arranged in a row on each spray pipe 1. The detachable connection method remains consistent with existing technology, such as threaded connection. The spray tower body 2 is equipped with at least one inlet pipe 210 communicating with its inner cavity. A receiving pipe 220 is coaxially located on the inner wall of the spray tower body 2 opposite each inlet pipe 210. The inner diameter of the receiving pipe 220 is greater than or equal to the outer diameter of the insertion end of the spray pipe 1. A bracket 4 is provided inside the inlet pipe 210. When one end of the spray pipe 1 equipped with nozzles 3 enters the inlet pipe 210... At this time, the bracket 4 allows the spray pipe 1 and the nozzle 3 to pass through and supports the spray pipe 1. One end of the spray pipe 1 and the nozzle 3 on it enter the spray tower body 2 through the inlet pipe 210 and the bracket 4 and are then inserted into the receiving pipe 220 directly opposite the inlet pipe 210. The end of the spray pipe 1 inserted into the receiving pipe 220 can be closed or open, preferably closed. In the case of openness, the receiving pipe 220 can actually be used as a cover for the spray pipe 1, while the other end of the spray pipe 1 is outside the inlet pipe 210 and is connected to the inlet pipe 210 by a flange. The flange connection facilitates the disassembly and assembly of the spray pipe 1 and the inlet pipe 210.
[0031] When it is required to inspect the nozzle 3, first disconnect the spray pipe 1 from the inlet pipe 210, then simultaneously pull the spray pipe 1 and the nozzle 3 out of the spray tower body 2, and then remove the nozzle 3 for inspection; after the inspection is completed, reinstall the nozzle 3 on the spray pipe 1, then re-insert one end of the spray pipe 1 with the nozzle 3 into the spray tower body 2 through the inlet pipe 210 and the bracket 4, and finally insert it into the receiving pipe 220 that is directly opposite the inlet pipe 210. Then reconnect the spray pipe 1 and the inlet pipe 210 with a flange to complete the inspection.
[0032] The entire maintenance process allows the nozzles to be pulled out of the tower for maintenance without personnel entering the tower body. The operation is simple and can be disassembled at will. Without increasing investment costs, it can effectively avoid the dangers of conventional maintenance, i.e., avoid safety accidents, and has obvious technical advantages. Since the spray pipe 1 and the nozzle 3 have a certain weight and the spray pipe 1 is also relatively long, the bracket 4 can be introduced to support the spray pipe 1 as a force point during the process of pulling out and re-inserting the spray pipe 1. On the one hand, it can easily ensure that the insertion end of the spray pipe 1 is aligned with the opening of the receiving pipe 220, so that the spray pipe 1 can be quickly inserted into the receiving pipe 220. On the other hand, it can suspend the nozzle 3 in the air to avoid damage to the nozzle 3, and at the same time reduce the labor intensity of the workers.
[0033] Example 2
[0034] like Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:
[0035] The bracket 4 includes two supports 410 and two arc-shaped support plates 420. The two supports 410 are fixed inside the inlet pipe 210. The support 410 and the inlet pipe 210 can be fixed by welding or bolt connection. The two supports 410 are located on both sides of the spray pipe 1. Each support 410 is provided with an arc-shaped support plate 420. The support 410 is located on the side of the arc-shaped support plate 420 away from the spray pipe 1. The side of the arc-shaped support plate 420 facing the spray pipe 1 is an arc-shaped surface adapted to the spray pipe 1. The two arc-shaped support plates 420 are located on both sides of the spray pipe 1 and support the spray pipe 1. They can effectively and stably support the spray pipe 1 without affecting the passage of the spray pipe 1 and the nozzle 3.
[0036] Furthermore, multiple ball bearings 430 are arranged in a row along the length of the spray pipe 1 on the arc-shaped surface of the arc-shaped support plate 420. Specifically, multiple holes are opened on the arc-shaped support plate 420, and a portion of the ball bearings 430 is embedded in the holes on the arc-shaped support plate 420. The ball bearings 430 on the arc-shaped support plate 420 are in contact with the pipe wall of the spray pipe 1. The ball bearings 430 can reduce the contact area, which is beneficial for the insertion and removal of the spray pipe 1.
[0037] Example 3
[0038] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below:
[0039] The inlet end of the inlet pipe 210 is provided with a first flange 5. The spray pipe 1 is fitted with a second flange 6 that is seamlessly connected to the inlet pipe 210 at one end. The spray pipe 1 and the second flange 6 can be seamlessly connected by welding. The second flange 6 and the first flange 5 are connected by bolts. The spray pipe 1 and the inlet pipe 210 can be disassembled and assembled by simply removing and installing the bolts.
[0040] Furthermore, a sealing gasket is provided between the first flange 5 and the second flange 6 to effectively prevent leakage.
[0041] Example 4
[0042] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on embodiment 3, as detailed below:
[0043] The second flange 6 is provided with at least two handles 7 on the outside. When inserting and removing the spray pipe 1, the handles 7 can be used as force points to facilitate the insertion and removal of the spray pipe 1.
[0044] Example 5
[0045] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below:
[0046] A third flange 8 is provided at one end of the spray pipe 1 outside the inlet pipe 210 to facilitate the connection of an external liquid supply pipe.
[0047] Example 6
[0048] like Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 5, as detailed below:
[0049] The receiving pipe 220 is equipped with a sealing ring 9 that fits onto the spray pipe 1, which can prevent the spray pipe 1 from shaking inside the receiving pipe 220.
[0050] Example 7
[0051] like Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 6, as detailed below:
[0052] The spray tower body 2 has two inlet pipes 210 connected to its inner cavity on the same radial cross section, which means that the spray tower body 2 has two spray pipes 1 on the same radial cross section, thus improving work efficiency.
