Description

Technical Field

[0001] The utility model relates to the technical field of emergency exhaust structures, in particular to an emergency exhaust structure for a laboratory. Background Art

[0002] Generally, the environmental requirements of laboratories are relatively high. Providing a stable environment for experimenters is also crucial for the accuracy of experimental data. However, the air in the laboratory must be exchanged with the outside air. In addition to bringing the required oxygen to the people in the laboratory, the outside air will also bring substances such as bacteria and dust in the outside air into the laboratory. At the same time, during the air exchange process, some substances generated in the laboratory will also be brought into the air, and these substances may cause environmental pollution. The current ventilation in laboratory buildings is all conventional exhaust fan ventilation, leading the air duct to the roof. The smell in the building and in the laboratory is unbearable, and the discharged gas is borne by the high-rise buildings around downwind, resulting in continuous disputes. There is no laboratory using downward exhaust, and there is no report on ventilation heat energy exchange and energy-free and good ventilation and air change. We newly design an emergency exhaust structure for a laboratory. Content of the Utility Model
