Description

Technical Field

[0001] This utility model belongs to the field of exhaust equipment technology, specifically referring to an intelligent, energy-saving and environmentally friendly exhaust device for laboratory use. Background Technology

[0002] Gases generated in the laboratory can be classified into harmless gases, harmful gases, and particulate matter. Among them, gases such as those produced by chemical reagent volatilization and toxic gases generated during experiments need to be effectively controlled and treated to prevent harm to the environment and human health.

[0003] Because the treatment of hazardous gases typically requires more complex and expensive technologies and equipment, the operating and maintenance costs are high. In contrast, the emission of harmless gases usually only requires a simple exhaust system, resulting in lower costs. Existing exhaust systems need to have intelligent control functions, capable of adjusting the exhaust volume and treatment method based on the gas concentration and type of hazardous substances in the laboratory; this is an issue that needs to be considered during the design phase. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a smart, energy-saving and environmentally friendly exhaust device for laboratory use, which is used to solve the problem of energy conservation and environmental protection for the emission of harmful substances.

[0005] The technical solution adopted in this application is as follows:

[0006] This solution provides a smart, energy-saving and environmentally friendly exhaust device for laboratory use, including an exhaust pipe with an exhaust port on one side of the bottom of the exhaust pipe;

[0007] The exhaust vent is equipped with a mounting flange for connecting to the laboratory fume hood. A clean air pipe is located at the end of the exhaust duct, and a toxic gas pipe is also provided on one side of the top of the exhaust duct. An inverted L-shaped air duct is formed between the exhaust vent and the clean air pipe. An airflow adjustment device is provided at the rear end of the air duct where it connects to the toxic gas pipe. The airflow adjustment device includes a flip-up baffle. A rotating shaft is provided on the inner wall of the exhaust duct. The rotating shaft drives the flip-up baffle to adjust its angle, thereby achieving a diversion effect. The height and width of the flip-up baffle are the same as the height and width of the air duct. When the flip-up baffle is perpendicular to the exhaust duct, the exhaust vent is connected to the toxic gas pipe, but not connected to the clean air pipe.

[0008] Preferably, the outer wall of the exhaust duct is equipped with a display, and the side of the exhaust duct near the exhaust port is equipped with a processor and a gas sensor group. The gas sensor group and the display are both connected to the processor, and the display is used to display the data detected by the gas sensor group.

[0009] Preferably, the air volume adjustment device further includes a rotating rod connected to the rotating shaft, an arc-shaped adjusting component fixed to the outer wall of the exhaust pipe, and a plug-in component. The arc-shaped adjusting component is arranged in the shape of a quarter circle and has a fixing groove on its surface. The rotating shaft is located at the center of the circle in which the arc-shaped adjusting component is located. The free end of the rotating rod has a fixing hole, and the fixing hole has a hollow fixing sleeve. The plug-in component is T-shaped and its small diameter end is inserted into the fixing groove. A return spring is provided between the plug-in component and the fixing sleeve.

[0010] Preferably, the exhaust vent is equipped with a filter, which includes a filter screen one and a filter screen two located on the upper and lower sides of the exhaust vent.

[0013] 1. Intelligent diversion based on the harmfulness of emitted substances guides harmful gases to a specialized treatment system, while harmless gases are directly emitted. This effectively reduces overall emission treatment costs, improves energy efficiency, and meets environmental protection requirements.

[0014] 2. Adjust the use of the air volume adjustment device according to the gas emission concentration to improve energy utilization efficiency while ensuring ventilation effect. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a smart, energy-saving, and environmentally friendly exhaust device for laboratory use, including an exhaust pipe 1. An exhaust port 11 is provided on one side of the bottom of the exhaust pipe 1. An installation flange 2 for connecting to a fume hood in the laboratory is provided at the exhaust port 11. A clean air pipe 3 is provided at the tail end of the exhaust pipe 1. A toxic gas pipe 4 is also provided on one side of the top of the exhaust pipe 1. An inverted L-shaped air duct 12 is formed between the exhaust port 11 and the clean air pipe 3. An airflow adjustment device 5 is provided at the rear end of the air duct 12 where it connects to the toxic gas pipe 4. The airflow adjustment device 5 includes a flip-up baffle 51. A rotating shaft 52 is provided on the inner wall of the exhaust pipe 1. The rotating shaft 52 drives the flip-up baffle 51 to adjust its angle, thereby achieving a diversion effect. The height and width of the flip-up baffle 51 are the same as the height and width of the air duct 12. When the flip-up baffle 51 is perpendicular to the exhaust pipe 1, the exhaust port 11 is connected to the toxic gas pipe 4, but the exhaust port 11 is not connected to the clean air pipe 3.

[0030] like Figure 5As shown, the air volume adjustment device 5 also includes a rotating rod 53 connected to the rotating shaft 52, an arc-shaped adjusting component 54 fixed to the outer wall of the exhaust pipe 1, and a plug-in component 55. The arc-shaped adjusting component 54 is arranged in a quarter-circle arc and has a fixing groove 58 on its surface. The rotating shaft 52 is located at the center of the circle where the arc-shaped adjusting component 54 is located. The free end of the rotating rod 53 has a fixing hole. The fixing hole has a hollow fixing sleeve 56. The plug-in component 55 is T-shaped and its small-diameter end is inserted into the fixing groove 58. A return spring 57 is provided between the plug-in component 55 and the fixing sleeve 56. By inserting the small-diameter end of the plug-in component 55 into the fixing groove 58 at different positions, the tilt angle of the flip baffle 51 can be changed, thereby adjusting the ventilation volume.

[0031] Combination Figure 1 , Figure 4 and Figure 6 As shown, a display 6 is provided on the outer wall of the exhaust pipe 1. A processor 7 and a gas sensor group 8 are provided on the side of the exhaust pipe 1 near the exhaust port 11. The gas sensor group 8 and the display 6 are both connected to the processor 7. The display 6 is used to display the data detected by the gas sensor group 8. The gas sensor group 8 includes a gas concentration sensor for detecting gas concentration and a toxic and harmful gas sensor for detecting gas type.

[0032] When using this structure, the angle of the flip baffle 51 is manually adjusted according to the gas concentration and harmfulness information displayed on the display 6. The air volume adjustment device 5 is used according to the gas emission concentration. The plug 55 is taken out from a set of fixed slots 58 and inserted into the corresponding fixed slot 58 to realize the change of the angle of the flip baffle 51 with respect to the air duct 12. The exhaust volume is adjusted according to actual needs to avoid excessive exhaust.

[0033] When the flip baffle 51 is perpendicular to the exhaust pipe 1, the exhaust port 11 is connected to the toxic gas pipe 4, but not connected to the clean gas pipe 3. Detoxification can be carried out through the toxic gas pipe 4. The system can intelligently divert the harmful gases according to the harmfulness of the emitted substances and guide the harmful gases to a special treatment system.

[0034] When the flip-up baffle 51 is parallel to the exhaust duct 1, the exhaust efficiency is maximized, and harmless gases are directly discharged. This effectively reduces the overall emission treatment cost, improves energy utilization efficiency, and meets environmental protection requirements. Adjusting the airflow regulating device 5 according to the gas emission concentration ensures effective exhaust while improving energy utilization efficiency.

[0035] Additionally, it should be noted that the gas duct 4 is also equipped with a reversible sealing plate, which is closed when the clean gas is discharged, and the air duct 12 is not connected to the gas duct 4. Forced ventilation equipment can be installed outside the clean gas duct 3 and the gas duct 4 as needed.

[0036] Example 2

[0037] To reduce the pressure of subsequent gas processing, combined with Figure 2 and Figure 4 As shown, a filter 9 is provided at the exhaust port 11. The filter 9 includes a first filter screen 91 and a second filter screen 92 located on the upper and lower sides of the exhaust port 11. A sandwich is formed between the first filter screen 91 and the second filter screen 92. The sandwich is filled with a filter material layer 93. The filter material layer 93 is made of filter cotton or activated carbon, which performs a preliminary filtration effect when exhausting.

[0038] As one embodiment, the tail diameter of the air purification pipe 3 is gradually reduced, which helps to reduce the resistance of the airflow during the exhaust process, improve the exhaust efficiency, and at the same time, the airflow gradually accelerates as it passes through, while reducing the formation of vortices and negative pressure zones, thereby reducing energy loss.

[0039] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art who design similar structures and embodiments without departing from the spirit of the present invention should all fall within the protection scope of the present invention.
