Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical fiber drawing process, and specifically relates to a gas capture unit for escaping gases. Background Technology
[0002] The main steps in the production process of polyester staple fiber are melt spinning and post-processing drawing. Throughout the process, to reduce static electricity, prevent fiber mildew, and reduce friction between the fiber and contact equipment, appropriate auxiliaries are added; these auxiliaries are generally organic compounds. In the post-drawing process of polyester staple fiber, high-temperature steam is used to heat, stretch, and set the fiber to ensure its mechanical properties and dimensional stability. Therefore, a mixture of organic matter and water vapor is inevitably generated during this process. This mixed vapor containing organic matter permeates the workshop, seriously affecting: 1. the production environment and the health of operators; 2. contaminating the finished fiber.
[0003] Currently, in the polyester staple fiber production industry, a long strip-shaped collection hood is installed above the post-drawing machine along the fiber drawing direction to draw in organic vapors and discharge them to the post-treatment unit for processing before being released. However, in practical applications, the most significant limitation of this structure is its poor containment of organic vapors. The vapors escape into areas not covered by the hood, resulting in poor collection efficiency. Furthermore, during the collection process, high-temperature humid steam (containing a small amount of organic oil vapor) generated by the high-temperature water tank, steam box, and steam injection device in the post-drawing stage condenses in parts of the collection hood structure, turning the organic vapors into organic liquids. These liquids drip onto the fiber bundles, causing fiber breakage and fuzzing. To prevent the spread of organic vapors and their impact on the workshop environment, product quality, and equipment lifespan, a technical solution to address these problems is urgently needed. Utility Model Content
[0004] The purpose of this invention is to provide an escape gas capture unit that can improve exhaust efficiency, facilitate the capture of organic water vapor, and make the opening angle and air inlet structure of the capture hood adapt to the steam rising characteristics.
[0005] The purpose of this utility model is achieved as follows: An escaping gas capture unit includes a channel trough, which includes an upper side plate, a lower side plate, a left side plate, and a right side plate forming a rectangle. A top baffle is fixedly connected to the front part of the upper side plate. The front parts of the left side plate and the right side plate are respectively fixed to the left baffle and the right baffle. The left baffle and the right baffle are arranged correspondingly to each other. A transverse connecting plate is provided between the front parts of the left baffle and the right baffle. The upper parts of the connecting plate, the left baffle, and the right baffle are all fixed to the top baffle. An upper mounting seat is provided on the lower side of the top baffle. A lower mounting seat is provided on the lower side plate. A capture unit is provided between the upper mounting seat and the lower mounting seat. The capture unit includes several honeycomb mesh plates arranged sequentially in a transverse direction.
[0006] This invention is used to collect organic vapor. A honeycomb mesh plate is added between the upper and lower mounting bases and installed at a 50° angle. The honeycomb mesh plate in the capture unit focuses on intercepting organic oil vapor particles. Left and right baffles are used to even out and guide airflow, optimizing the gas collection effect. Organic liquid collection channels are created around the perimeter of the capture unit to guide the liquid downwards for easy collection. The capture unit is primarily made of 304 stainless steel, which is corrosion-resistant, easy to wipe, and easy to clean. This capture hood emphasizes dehumidification and drainage, has a simpler structure, and is equipped with a condensation collection device to reduce liquid dripping. Compared with existing technologies, the advantages of this invention are: improved exhaust efficiency with a focus on "organic water vapor capture," and the capture hood's opening angle and air inlet structure are adapted to the rising characteristics of steam.
[0007] As a further improvement of this invention, the honeycomb mesh panel is inclined at an angle of 50° to the horizontal plane. The 50° inclined honeycomb mesh panel facilitates steam collection.
[0008] As a further improvement of this utility model, the honeycomb mesh panel is made of 304 stainless steel. The honeycomb mesh panel is a 304 stainless steel plate covered with multiple honeycomb holes, the diameter of which is 1-2mm.
[0009] As a further improvement of this utility model, both the left and right side plates are trapezoidal, and the length of the lower side plate is greater than the length of the upper side plate.
[0010] As a further improvement of this utility model, the lower side plate has a lower baffle plate with an L-shaped cross-section at its front edge, the connecting plate has an upper baffle plate with an L-shaped cross-section at its lower edge, the left baffle plate has a left baffle plate with an L-shaped cross-section at its lower edge, and the right baffle plate has a right baffle plate with an L-shaped cross-section at its lower edge. The upper baffle plate, lower baffle plate, left baffle plate, and right baffle plate form a rectangle, and a drain port is provided on the lower baffle plate. The upper baffle plate, lower baffle plate, left baffle plate, and right baffle plate form a U-shaped organic liquid collection tank, through which organic liquid and high-temperature humid steam (containing a small amount of organic oil vapor) can be discharged. The high-temperature humid steam condenses upon heating, turning the organic high-temperature humid steam into organic liquid, which can then be discharged through the drain port.
[0011] As a further improvement of this utility model, the honeycomb mesh panel is provided with horizontal fixing plates on both the upper and lower sides. The fixing plates on the upper and lower sides of the honeycomb mesh panel are fixedly connected to the upper mounting base and the lower mounting base respectively by several fasteners. By installing and removing the fasteners on the fixing plates, it is convenient to install and remove the honeycomb mesh panel. Attached Figure Description

[0019] The honeycomb mesh panel 8 is made of 304 stainless steel. The honeycomb mesh panel 8 is a 304 stainless steel plate covered with multiple honeycomb holes, the diameter of which is 1-2mm.
[0020] Both the left side plate 1c and the right side plate 1d are trapezoidal, and the length of the lower side plate 1b is greater than the length of the upper side plate 1a.
[0021] The lower side plate 1b has a lower baffle plate 9 with an L-shaped cross-section at its front edge.
