Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an energy-saving purification device for laboratory decoration. Background Art

[0002] As global awareness of environmental protection increases, reducing energy consumption and emissions have become important considerations in building design and operation. Laboratories, as important places for scientific research, often need to conduct chemical experiments, biological cultivation and other activities, which may produce harmful gases or particulate matter and have a negative impact on indoor air quality. High-efficiency and energy-saving purification devices can not only remove these pollutants, but also maintain the comfort and safety of the indoor environment.

[0003] The patent with the patent announcement number CN209524591U discloses an energy-saving purification device for laboratory decoration, including a shell, with an air inlet and an air outlet on both sides of the shell respectively, and two mutually connected filter pipes are continuously arranged in the shell along the direction from the air inlet to the air outlet, which are the first filter pipe and the second filter pipe respectively; the filter pipe is U-shaped, and the air inlet is connected to the inlet of the first filter pipe through an exhaust device; the first filter pipe is provided with multiple sterilization layers, and the second filter pipe is provided with multiple formaldehyde decomposition layers; the outlet of the second filter pipe is connected to the air outlet through a filter cartridge, and the filter cartridge is provided with activated adsorption carbon.

However, different departments of the laboratory may require different environmental conditions to support specific types of experiments or research, and the purification device lacks adjustable components. It has limitations in use in laboratories with different humidity and temperature requirements. For example, a microbiology laboratory may require a strictly controlled sterile environment, while a chemical laboratory may be more concerned with the removal of harmful gases, making it difficult to flexibly adjust to meet the needs of various departments. Therefore, in view of the shortcomings of the existing technology, we have designed an adjustable and multifunctional energy-saving purification device for laboratory decoration.

[0024] like Figure 3 As shown, the ventilation frame 3 is provided with an atomizing nozzle 7, and the atomizing nozzle 7 is installed on the top of the ventilation frame 3. The nozzle of the atomizing nozzle 7 is located inside the top wall of the ventilation frame 3. The upper part of the atomizing nozzle 7 can be externally connected to a water injection pipe. After the atomizing nozzle 7 is connected to the water source, the air flowing through the ventilation frame 3 is humidified; the ventilation frame 3 is also provided with a filter 15, and the filter 15 is detachably installed at the right air outlet of the ventilation frame 3. The filter 15 can filter and prevent harmful gases in the laboratory from flowing back to the ventilation frame 3.

[0025] like Figure 2As shown, the exhaust assembly includes an adsorption plate II 901, an exhaust fan 902 and an exhaust hood 903. The adsorption plate II 901 is arranged in the front compartment of the installation frame II 2, and the exhaust fan 902 is installed in the front compartment of the installation frame II 2. The front right side of the installation frame II 2 is connected to the exhaust hood 903, and the air outlet of the exhaust hood 903 is connected to a pipe, and the pipe is externally connected to the harmful gas processing and collection equipment; the adsorption plate I6 and the adsorption plate II 901 are both detachably installed in the installation frame II 2, and the adsorption plate I6 and the adsorption plate II 901 are activated carbon plates or porous ceramic plates.

[0026] like Figure 2 and Figure 3 As shown, it also includes a connecting cover 8 and a cover frame 81. A vent is opened on the left side wall of the installation frame I1.

[0028] When using the purification device, the construction personnel need to first stably install the installation frame I1 on the ceiling of the laboratory by screws, so that the installation frame I1 and the installation frame II2 form a closed space on the ceiling. After the purification device is installed on the ceiling, the pipe of the air inlet hood 4 is connected to the outside fresh air. When the air in the laboratory needs to be updated, the exhaust fan 5 is activated. The exhaust fan 5 draws the outside fresh air into the air inlet hood 4 through the pipe. The fresh air flows into the rear compartment of the installation frame II2 after passing through the air inlet hood 4. When the fresh air flows through the installation frame II2, the dust or impurities therein will be adsorbed by the adsorption plate I6. The fresh air filtered by the adsorption plate will flow into the ventilation frame 3. The fresh air after flowing through the ventilation frame 3 will be filtered by the filter 15 again and discharged into the laboratory. When the air in the laboratory needs to be humidified, the atomizing nozzle 7 is connected to an external water source, and the fresh air flowing through the ventilation frame 3 is sprayed with water for humidification through the atomizing nozzle 7, so that the fresh air flowing out of the ventilation frame 3 is mixed with a certain amount of moisture. When the waste gas or harmful gas in the laboratory needs to be treated, the air is humidified by starting The motor 11 is used to drive the winding drum 12 to rotate forwardly through the output shaft. The forward-rotating winding drum 12 will continuously lower the wound pull rope 14, and the relaxed pull rope 14 will gradually lower the cover frame 81. The user stretches the connecting cover 8 to lower the cover frame 81 to the location where the exhaust gas needs to be treated. After the cover frame 81 is covered at the exhaust gas generation point, the exhaust fan 902 is activated. The exhaust fan 902 will draw the exhaust gas entering the connecting cover 8 and the cover frame 81 into the installation frame Ⅰ1. The exhaust gas flows from the installation frame Ⅰ1 to the installation frame Ⅱ2. The drawn-in exhaust gas will be safely filtered by the adsorption plate II 901 and then flow into the exhaust hood 903. Finally, the filtered exhaust gas will enter the subsequent exhaust gas treatment or collection device through the external pipe on the exhaust hood 903. After the exhaust gas is treated, the motor 11 drives the winding drum 12 in reverse, so that the winding drum 12 continuously winds and tightens the pull rope 14. The tightened pull rope 14 can automatically retract the cover frame 81 upward to the installation frame I1 by pulling the connecting rod 10, saving the workload of manually recovering the connecting cover 8 and the cover frame 81.
