Description

Technical Field

[0001] This utility model relates to a waste gas particulate matter settling pipe, and more particularly to a waste gas pipe for production lines with a large amount of crushed or solidified organic matter, belonging to the field of waste gas treatment. Background Technology

[0002] In many industries, such as building materials processing, ore crushing, plastic recycling, and metal grinding, production lines inevitably generate a large number of fine solid particles. These particles may include dust, debris, fibers, or fine particulate matter, which are carried into the exhaust gas ducts by high-temperature airflow or mechanical action during production. If not treated promptly and effectively, these solid particles can easily accumulate in the exhaust gas ducts, causing partial blockages or increased air resistance, thereby reducing the operating efficiency of the exhaust gas treatment system. Furthermore, particulate matter causes significant wear and tear on equipment and filters, potentially increasing maintenance costs.

[0003] In chemical, pharmaceutical, and plastics processing industries, certain organic compounds exist in a gaseous or liquid state during high-temperature operations, but solidify at the end of the process or during cooling. When these organic compounds cool in exhaust gas pipelines, they may form a solid deposit layer on the inner wall of the pipeline, gradually accumulating and causing blockages or even completely blocking the flow of exhaust gas. This situation is particularly common in the cooling or post-processing stages of production lines. The solidified organic compounds not only reduce the ventilation efficiency of the pipelines but may also increase the difficulty of cleaning and maintenance. To avoid pipeline blockages caused by the accumulation of solid particles or solidified organic compounds, it is necessary to design special pipelines and exhaust gas treatment equipment to improve the wear resistance and anti-clogging performance of the equipment.

[0004] Therefore, in light of this context, there is a need to develop specialized waste gas treatment equipment and technologies to effectively address the challenges of treating waste gas containing particulate matter and solidified organic matter, and to improve the efficiency and reliability of waste gas treatment systems. Utility Model Content

[0005] In view of the above-mentioned defects in the existing technology, the purpose of this utility model is to propose a waste gas pipeline for production lines with a large amount of crushed or solidified solid particles or organic matter.

[0006] The objective of this utility model will be achieved through the following technical solution:

[0007] A waste gas particulate matter settling pipeline includes a large particulate matter settling area and a particulate matter cyclone agglomeration settling area; the particulate matter agglomeration settling area is equipped with inclined separation plates, which are mainly divided into semi-elliptical and elliptical types; both areas are equipped with settling collection chambers, which are opened and closed by threaded openings, and the entire pipeline is connected to the waste gas pipeline through flanges.

[0008] Preferably, the length of the large particle settling zone is the actual pipe diameter width, and the depth of its collection chamber is determined according to the content of large particles in the exhaust gas, which is 1 to 1.5 times the pipe diameter;

[0009] Preferably, the length of the particulate matter agglomeration and settling zone is the actual pipe diameter width, and the collection chamber is a trapezoidal collection chamber that is wider at the top and narrower at the bottom;

[0010] Preferably, the inclined separation plate is made of heat-resistant material, and the detachable plate structure is anchored inside the pipe. The semi-elliptical and elliptical separation plates do not overlap in the vertical direction, but are connected in the horizontal direction, with an inclination angle of 45°-60°.

[0011] Preferably, each collection chamber is equipped with a vertical baffle, 5-10cm long, at its end;

[0012] Preferably, the collection chamber is opened and closed via a threaded opening at the bottom to collect the collected materials;

[0013] Preferably, the pipeline is connected to the exhaust gas pipeline via a flange.

[0014] The outstanding advantages of this invention are as follows: The invention employs a simple internal structure, utilizing the principles of physical sedimentation and cyclone dust removal to separate solid particles from the exhaust gas. After the exhaust gas enters the pipeline, larger solid particles settle into the collection chamber. In the second zone, a cyclone is formed using a separation plate to agglomerate or centrifuge smaller particles that did not settle in the first zone, sending them to the collection chamber. Simultaneously, the collection chamber can be easily opened and closed, improving particle collection efficiency. Furthermore, the inclined separation plate adopts a detachable plate structure and has heat resistance, preventing scale buildup and facilitating the initial cooling of hot exhaust gas.

[0015] In summary, this utility model has excellent performance and a simple and ingenious structure. It can effectively separate a large number of solid particles or organic matter that has been cooled and transformed into solids in waste gas. It is suitable for crushing, grinding, cooling and other processes and can be installed at the front end of waste gas pretreatment.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Attached Figure Description

[0020] This utility model discloses a waste gas particulate matter settling pipe.

[0021] like Figure 1 As shown, this utility model designs a settling pipe for solid particulate matter in exhaust gas. This pipe can be flexibly installed at the exhaust gas emission points of processes such as crushing, pulverizing, and cooling, or used as a pretreatment device at the front end of exhaust gas pretreatment equipment (such as a bag filter). The pipe's interior, from left to right, features a first settling zone and a second settling zone for the efficient, phased collection and removal of large particles from the exhaust gas. The first settling zone, through gravity, concentrates larger solid particles into a collection chamber 41. The second settling zone is designed with two rows of semi-elliptical inclined separation plates 31 at the top and bottom, and a central elliptical inclined separation plate 32. These separation plates are arranged at a 45° angle, ensuring they do not overlap vertically and seamlessly connect horizontally, thus utilizing the cyclone centrifugal effect and particle agglomeration effect to efficiently settle particulate matter into the collection chamber 42. Each collection chamber is also equipped with a vertical baffle 33 to prevent the settled particles from being disturbed by secondary airflow.

[0022] The working process of this utility model is briefly described below: In actual operation, this utility model is applicable to various types of waste gas containing solid particles or that may solidify after cooling. For waste gas containing a large amount of solid particles, the waste gas first enters the first settling zone, where larger particles are directly separated and collected into collection chamber 41 by gravity settling. Subsequently, the waste gas enters the second settling zone, where the cyclone effect generated by the inclined separation plate in the zone agglomerates the particles into larger particles by centrifugal force, which then further settle into collection chamber 42. For organic waste gas containing organic matter that can solidify after high-temperature cooling, the waste gas enters the first settling zone, where large particles are also settled into collection chamber 41 by gravity. In the second settling zone, the organic components in the waste gas cool and solidify on the surface of the inclined separation plate, forming larger particles that then settle into collection chamber 42. In addition, during the cooling process, centrifugal force can further separate and collect some solid particles. This design not only effectively improves the separation efficiency of particles but also ensures the system's adaptability to different waste gas components, thus possessing higher application value in diverse industrial scenarios.

[0023] This invention employs a simple internal structure, utilizing the principles of physical sedimentation and cyclone dust removal to separate solid particles from waste gas. After the waste gas enters the pipeline, larger solid particles settle into the collection chamber. In the second zone, a cyclone is created using separation plates to agglomerate or centrifuge smaller particles from the first zone, sending them to the collection chamber. Simultaneously, the collection chamber can be easily opened and closed, improving particle collection efficiency. Furthermore, the inclined separation plates feature a detachable plate structure and heat resistance, preventing scale buildup and facilitating initial cooling of the hot waste gas. The ingenious arrangement of the inclined separation plates not only enhances cooling and agglomeration effects but also reduces the risk of secondary dust generation. This flexibility makes it suitable for various waste gas treatment scenarios, improving the equipment's adaptability and processing efficiency while effectively reducing operating costs and resource waste.
