Description

Technical Field

[0001] The present application relates to the technical field of fume hoods, and in particular to an energy-saving fume hood. Background Art

[0002] Fume hoods, as an indispensable safety equipment in laboratories, have the main function of ensuring the air quality and safety in the laboratory. In biochemical experiments, fume hoods provide an effective working environment, exhausting harmful gases to the outside through the internal fan system, while introducing fresh air from the front of the cabinet to maintain air circulation in the cabinet.

[0003] For example, a Chinese patent with announcement number CN210966299U discloses a laboratory energy-saving spray fume hood, including a cabinet body and a drying box; a purification box is fixedly installed in the middle of the top inner wall of the cabinet body, a through pipe is horizontally arranged at the upper end of the inner part of the purification box, and the bottom end of the through pipe is connected to a plurality of groups of nozzles, and an air inlet pipe is installed through the front and rear sides of the upper left end of the cabinet body, and the right end of the air inlet pipe is connected to the upper end of the left inner wall of the purification box; the exhaust fan is controlled to draw indoor air into the purification box, and the water pump is controlled to guide the liquid in the medicine tank into the through pipe through the water inlet pipe and spray it out through the nozzle, so as to further disinfect and purify the air discharged from the air inlet pipe.

[0004] The above-mentioned disinfection spray method still has certain limitations: first, due to the limited contact area between the gas and the spray liquid, only part of the pollutants in the gas can react with the liquid, and most of the pollutants escape because they cannot fully contact the liquid, and the harmful components in the gas cannot be effectively removed; in addition, due to the insufficient contact area, it not only affects the purification effect, but also leads to a decrease in the utilization rate of the liquid. In the process of contact with the gas, the liquid cannot fully exert its chemical reaction potential, which causes a large amount of liquid to be wasted in the purification process and not effectively utilized.

[0005] Therefore, in order to solve the above problems, the present application provides an energy-saving fume hood.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
