Description

Technical Field

[0001] This utility model relates to a gas-liquid separation device, and more particularly to a gas-liquid separation device for a blower exhaust pipe. Background Technology

[0002] The gas-liquid separation device for the drying mold exhaust pipe is a specialized device designed to separate liquids from gases. It is commonly used in industrial processes for waste gas treatment or as a tail gas emission system after specific processes (such as plastic molding and casting). Its main function is to remove liquid components from compressed air containing moisture or other liquid particles, ensuring that the exhaust gas is as dry and clean as possible, thereby protecting the environment and maintaining the efficient operation of the production system. The drying mold exhaust pipe for the annealing furnace is a crucial component connecting the annealing furnace to the external environment. Its main function is to exhaust the humid, hot air, volatiles, and other possible gases or vapors generated within the furnace during the annealing process. This exhaust pipe is essential for ensuring the safety, efficiency, and product quality of the annealing process.

[0003] To further purify the exhaust gas and ensure that the gas discharged from the annealing furnace drying mold exhaust pipe meets emission standards, the existing technology often places the end of the annealing furnace drying mold exhaust pipe in the cooking oil bath to achieve gas-liquid separation. However, the exhaust gas discharged from the annealing furnace drying mold exhaust pipe is large, and placing it directly in the cooking oil bath will cause the cooking oil to be blown out by the gas discharged from the annealing furnace drying mold exhaust pipe, resulting in cooking oil splashing, which poses a huge safety hazard. In addition, the cooking oil bath contains copper mud, which will block the exhaust pipe after a period of time, thus affecting the annealing efficiency.

[0004] Therefore, it is necessary to design a gas-liquid separation device for the exhaust pipe of the drying mold to achieve efficient gas-liquid separation of the fluid discharged from the exhaust pipe. Utility Model Content

[0005] The technical implementation scheme of this utility model is as follows: a gas-liquid separation device for a blow-drying mold exhaust pipe, comprising a separation cylinder, a blow-drying mold exhaust pipe body, a guide cap, a rotating shaft, and a spiral separator. The blow-drying mold exhaust pipe body is connected to the separation cylinder. The top opening of the separation cylinder is a gas discharge port for gas-liquid separation. The end of the blow-drying mold exhaust pipe body extending into the inner side of the separation cylinder is connected to the guide cap. The guide cap is installed on the inner wall of the separation cylinder. The bottom of the guide cap is open and a rotating shaft is rotatably installed inside the guide cap. A spiral separator is installed on the rotating shaft. The spiral separator is used to rotate and disperse the fluid flowing out of the blow-drying mold exhaust pipe body. Both the rotating shaft and the spiral separator are located inside the guide cap, and the spiral separator is located below the connection between the blow-drying mold exhaust pipe body and the guide cap.

[0006] Optionally, D-shaped inclined baffles are arranged longitudinally side by side on the inner side of the separator. The openings between the D-shaped inclined baffles and the inner wall of the separator are staggered. The D-shaped inclined baffles are located below the guide cap. The liquid dispersed by the spiral separator falls downward onto the D-shaped inclined baffles and is guided by them into the lower inner cavity of the separator.

[0007] Optionally, a filter screen is inclinedly provided on the inner side of the lower part of the separator, and the filter screen is used to filter the fluid.

[0008] Optionally, the lower part of the separator is connected to a liquid outlet pipe and a drain pipe. The liquid outlet pipe is used to discharge the liquid filtered by the filter screen outside the separator, and the drain pipe is used to discharge the impurities and liquid blocked by the filter screen outside the separator.

[0009] Optionally, a valve switch is installed on the sewage pipe to control the opening and closing of its internal cavity.

[0010] Optionally, a cleaning pipe is connected to the upper part of the separator cylinder. The cleaning pipe is located above the exhaust pipe body of the drying mold. The end of the cleaning pipe that extends into the inner cavity of the separator cylinder is connected to a spiral nozzle. The spiral nozzle rotates and sprays liquid to rinse the inner wall of the separator cylinder.

[0011] The present invention has the following advantages: 1. The design of combining a spiral separator with a D-shaped inclined baffle can effectively utilize the dual effects of centrifugal force and gravity to achieve efficient separation of liquid particles in gas. In particular, the device exhibits excellent capture ability for fine droplets and lightweight solid particles.

[0012] 2. The separated gas is discharged through the gas outlet above the guide cap, ensuring that the clean gas will not come into contact with the separated liquid again, thereby avoiding the risk of secondary pollution.

[0013] 3. The staggered arrangement of D-shaped inclined baffles not only guides the liquid to slide down a specific path into the lower inner cavity of the separator, but also further promotes the accumulation of liquid and improves separation efficiency; at the same time, this design helps to reduce gas backflow and enhance the separation effect.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] Example: A gas-liquid separation device for the exhaust pipe of a blower drying mold, such as Figures 1-3 As shown, the device includes a separation cylinder 1, a drying mold exhaust pipe body 2, a flow guide cap 10, a rotating shaft 11, and a spiral separator 12. The drying mold exhaust pipe body 2 is connected to the separation cylinder 1. The top opening of the separation cylinder 1 is a gas discharge port 6 for gas-liquid separation. The end of the drying mold exhaust pipe body 2 extending into the inner side of the separation cylinder 1 is connected to the flow guide cap 10. The flow guide cap 10 is installed on the inner wall of the separation cylinder 1. The bottom of the flow guide cap 10 is open, and the rotating shaft 11 is rotatably installed inside the flow guide cap 10. The spiral separator 12 is installed on the rotating shaft 11. The spiral separator 12 is used to guide the fluid flowing out of the drying mold exhaust pipe body 2 into the air. The rotating shaft 11 and the spiral separator 12 are both located inside the guide cap 10. The spiral separator 12 is located below the connection between the exhaust pipe body 2 of the drying mold and the guide cap 10. When the fluid in the exhaust pipe body 2 of the drying mold flows to the spiral separator 12 through the guide cap 10, the spiral separator 12 rotates to disperse the fluid. Under the action of centrifugal force of the spiral separator 12, the liquid is thrown out by the spiral separator 12 and falls down along the inner wall of the guide cap 10, while the gas is discharged through the notch at the bottom of the guide cap 10 and then discharged upward through the gas discharge port 6 to the outside of the separation cylinder 1.

[0021] like Figure 2 As shown, D-shaped inclined baffles 9 are arranged longitudinally side by side on the inner side of the separation cylinder 1. The openings between the D-shaped inclined baffles 9 and the inner wall of the separation cylinder 1 are staggered. The D-shaped inclined baffles 9 are located below the guide cap 10. The liquid dispersed by the spiral separator 12 falls downward onto the D-shaped inclined baffles 9 and is guided by them into the lower inner cavity of the separation cylinder 1. It is worth noting that the optimal angle of inclination of the D-shaped inclined baffles 9 and the spacing between them need to be determined experimentally to ensure that the liquid can slide down smoothly and minimize the possibility of gas backflow.

[0022] like Figure 2 and Figure 4As shown, a filter screen 13 is inclinedly arranged on the inner side of the lower part of the separation cylinder 1. The filter screen 13 divides the inner cavity of the separation cylinder 1 into two areas. The filter screen 13 is used to filter the fluid and block impurities, thereby achieving the effect of purifying the liquid.

[0023] like Figure 1 and Figure 4 As shown, the lower part of the separator 1 is connected to the liquid outlet pipe 3 and the drain pipe 4. The liquid outlet pipe 3 is used to discharge the liquid filtered by the filter screen 13 out of the separator 1. The drain pipe 4 is used to discharge the impurities and liquid blocked by the filter screen 13 out of the separator 1. A valve switch 5 is installed on the drain pipe 4 to control the opening and closing of its inner cavity. By controlling the opening or closing of the valve switch 5, the impurities can be cleaned periodically.

[0024] Moist, hot air (or other liquid-containing gas) containing moisture and other liquid particles is introduced into the guide cap 10 in the separator cylinder 1 through the blower exhaust pipe body 2. When the liquid-containing gas flows through the guide cap 10, the spiral separator 12 starts to work, using centrifugal force to throw the liquid droplets in the gas to the outside, forming a high-speed rotating flow field around the central axis. This process effectively separates most of the liquid from the gas and moves them downwards. The separated gas is discharged outside the separator cylinder 1 through the gas discharge port 6. The separated liquid falls downwards along the bottom opening of the guide cap 10 and then impacts the D located below the guide cap 10. On the inclined baffles 9, the design of these baffles allows the liquid to slide along their surface under the action of gravity and be guided to the lower inner cavity of the separator 1 through the staggered openings, further promoting the accumulation and discharge of the liquid, and effectively blocking the gas, which is discharged upward through the gas discharge port 6; the liquid falling from the inclined baffles 9 falls downward onto the filter screen 13, the filter screen 13 filters the liquid, and the filtered liquid flows out of the outside of the separator 1 through the liquid outlet pipe 3. The impurities blocked by the filter screen 13 remain in the separator 1. By controlling the valve switch 5 to open the drain pipe 4 for sewage discharge, the impurities are discharged to the outside of the separator 1.

[0025] like Figure 2 As shown, a cleaning pipe 7 is connected to the upper part of the separation cylinder 1. The cleaning pipe 7 is located above the exhaust pipe body 2 of the drying mold. The end of the cleaning pipe 7 that extends into the inner cavity of the separation cylinder 1 is connected to a spiral nozzle 8. The spiral nozzle 8 rotates and sprays liquid to rinse the inner wall of the separation cylinder 1. The cleaning pipe 7 is used to input cleaning liquid. The cleaning liquid is sprayed out through the spiral nozzle 8 to clean the inner wall of the separation cylinder 1, thereby achieving the cleaning effect of automatically cleaning the separation cylinder 1.

[0026] When the inner wall of the separator 1 needs to be cleaned, the cleaning liquid is introduced into the separator 1 through the cleaning pipe 7, and the cleaning liquid is sprayed onto the inner wall of the separator 1 through the spiral nozzle 8 to rinse the inner wall of the separator 1, ensuring the cleanliness of the inner wall of the separator 1 and extending the service life of the equipment.

[0027] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
