Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a spray pipe. Background Technology

[0002] Waste gas treatment is a crucial environmental protection task in industrial production. Waste gases, especially those containing particulate matter, dust, harmful gases, and potentially flame-retardant substances, will have a significant impact on the environment and human health if released directly into the atmosphere without proper treatment. To effectively treat these waste gases, the industrial sector widely employs various waste gas treatment technologies and equipment.

[0003] Waste gas treatment systems typically consist of three main stages: waste gas collection, transportation, and treatment. Waste gas collection is primarily carried out through waste gas pipelines, introducing waste gas from the production source into the treatment equipment. However, during waste gas transportation, particulate matter and harmful substances in the waste gas may accumulate inside the pipelines, leading to blockages, wear, and reduced treatment efficiency. Furthermore, if the waste gas contains flame-retardant gases, combustion within the pipelines will spread rapidly, causing severe damage to the pipelines and downstream treatment equipment, and may even trigger a fire. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, such as the potential deposition of particulate matter and harmful substances in the exhaust gas inside the pipeline during the pipeline transportation process, and the rapid spread of flame-retardant gases that ignite inside the pipeline, causing serious damage to the pipeline and downstream treatment equipment, and even leading to fire accidents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spray pipe includes a pipe body, a drain shell communicating with the lower part of the pipe body, a spray head on the upper part of the pipe body away from the drain outlet, and a cleaning component below the drain shell.

[0007] Preferably, a through hole is provided on the upper side of the pipe body near the drain shell, and an observation shell is provided in the through hole. The observation shell is provided with an observation port, and the observation port is provided with an observation window to facilitate observation of the interior. The user can observe the interior of the pipe body through the observation window.

[0008] Preferably, the cleaning component includes a connecting pipe and a positioning ring. A positioning rod is provided on the outer side of the positioning ring. The positioning ring is located on the inner side of the connecting pipe end. The positioning rod is connected to the inner wall of the connecting pipe. A rotating rod is provided on the positioning ring. A spiral impeller is provided on the rotating rod. The spiral impeller can accelerate the discharge speed of wastewater and at the same time clean the inner wall of the connecting end to prevent particles from adhering.

[0009] Preferably, the rotating rod is rotatably mounted on the positioning ring via a bearing, which enables the rotating rod to rotate, ensuring that the threaded impeller can drive the rotating rod to rotate.

[0010] Preferably, the sewage discharge shell is provided with a connecting end, and the connecting pipe is connected to the connecting end by a threaded connection, which facilitates the installation and removal of the cleaning components.

[0011] Preferably, the rotating rod is provided with a fixing rod, and the fixing rod is provided with a cleaning plate for cleaning the inside of the connecting end. The cleaning plate can scrape the inside of the connecting end to prevent deposits from adhering.

[0012] Preferably, the cleaning plate has an arc-shaped end that contacts the inner side of the connecting end. When the arc-shaped end contacts the connecting end, it maintains only slight contact to avoid excessive friction and ensure that the spiral impeller can rotate smoothly.

[0013] Preferably, the connecting pipe includes a first pipe and a second pipe, which are detachably connected. The second pipe can be externally connected to a pipe for wastewater transportation, so that the discharged wastewater can be transported to the wastewater treatment equipment for treatment. The rotatable connection between the first pipe and the second pipe makes it easy for the user to separate the connecting pipe from the connecting end during maintenance or repair.

[0014] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0015] 1. This utility model, through the set pipe body and the spray head set in the pipe body, can effectively settle large particulate pollutants in the exhaust gas, which can effectively improve the efficiency of subsequent exhaust gas treatment and reduce the burden on subsequent treatment equipment. The spray head not only has the function of exhaust gas pretreatment, but also has the function of fire protection. In the event of accidental combustion of flame-retardant gas, it can use water mist to form a fire extinguishing barrier in the pipe body, effectively blocking the spread of fire, protecting the safety of the entire exhaust gas treatment system and even the surrounding environment, and reducing the risk of fire.

[0016] 2. The cleaning components, through the spiral impeller, can accelerate the discharge of sewage and sediment, and also achieve automatic cleaning of the inner wall of the pipe through the cleaning plate, reducing blockage and scale problems, reducing the frequency and cost of manual maintenance, and improving the stability and operating efficiency of the system.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0029] Please see Figures 1-6 A spray pipe includes a pipe body 1, a drain shell 3 communicating with the lower part of the pipe body 1, a cleaning component 5 below the drain outlet of the drain shell 3, a spray head 4 on the upper part of the pipe body 1 away from the drain shell 3, an installation port 11 on the pipe body 1, the spray head 4 being installed on the installation port 11, a through hole on the upper part of the pipe body 1 near the drain shell 3, an observation shell 2 in the through hole, an observation port on the observation shell 2, and an observation window inside the observation port for easy observation of the interior, allowing the user to observe the exhaust gas flowing inside the pipe body 1 through the observation window.

[0030] Furthermore, the cleaning component 5 includes a connecting pipe 51 and a positioning ring 52. A positioning rod 53 is provided on the outer side of the positioning ring 52. The positioning ring 52 is placed inside the end of the connecting pipe 51. The positioning rod 53 is connected to the inner wall of the connecting pipe 51. A rotating rod 54 is provided on the positioning ring 52. A spiral impeller 55 is provided on the rotating rod 54. The rotation of the spiral impeller 55 forms a vortex, which can accelerate the discharge of wastewater. The rotating rod 54 is rotatably mounted on the positioning ring 52 through a bearing. The bearing enables the rotating rod 54 to rotate, ensuring that the spiral impeller 55 drives the rotating rod 54 to rotate more smoothly.

[0031] Furthermore, the drain shell 3 is provided with a connecting end 31 at the drain outlet, and the connecting end 31 extends downward with a vertical height. One end of the connecting pipe 51 is connected to the connecting end 31 by a threaded connection, which facilitates the installation and removal of the cleaning component 5. The other end of the connecting pipe 51 is connected to the external drain pipe.

[0032] It should be noted that the rotating rod 54 is equipped with a fixing rod 56, and the fixing rod 56 is equipped with a cleaning plate 57 for cleaning the inner side of the connecting end 31. The cleaning plate 57 can scrape off the inner wall of the connecting end 31 to prevent deposits from adhering.

[0033] It should be added that the cleaning plate 57 is provided with an arc-shaped end, which contacts the inner side of the connecting end 31. When the arc-shaped end contacts the connecting end 31, it only maintains slight contact to avoid excessive friction and ensure that the spiral impeller 55 can rotate smoothly.

[0034] The connecting pipe 51 includes a first pipe 511 and a second pipe 512. The first pipe 511 and the second pipe 512 are connected by a thread or a snap-fit. The second pipe 512 can be connected to an external pipe for wastewater transportation, so that the discharged wastewater can be transported to the wastewater treatment equipment for treatment. The detachable connection between the first pipe 511 and the second pipe 512 makes it easy for users to separate the connecting pipe 51 from the connecting end 31 during maintenance or repair.

[0035] In use, the pipe body 1 is installed on the exhaust gas conveying pipeline by welding or flange connection. The spray head 4 is connected to a water supply device to supply water into the spray head 4. The water entering the spray head 4 is sprayed out, which can treat the exhaust gas to settle. Large particles settle to the bottom drain shell 3, where they are collected and discharged. The sprayed water can also be used for fire fighting. When the exhaust gas contains flame-retardant gas and combustion occurs, the spray can block the fire in the pipeline, prevent it from spreading in the pipeline, and prevent fire accidents.

[0036] When the sprayed water flows below the pipe body 1 and converges at the drain shell 3, the water flow drives the spiral impeller 55 to rotate. The rotating spiral impeller 55 creates a vortex that accelerates the discharge speed of the wastewater. Furthermore, the rotating spiral impeller 55, via the fixed rod 56, drives the cleaning plate 57 to rotate as well. The rotating cleaning plate 57 rotates along the connecting end 31, thereby reducing particle adhesion to the inner wall of the connecting end 31, preventing deposits from accumulating, and preventing blockage and corrosion. It is worth noting that after the exhaust gas settles, the solid particles are not large enough to affect or impede the rotation of the spiral impeller 55.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
