Laboratory ventilation system

Abstract

The invention relates to the technical field of laboratory ventilation and discloses a laboratory ventilation system. The laboratory ventilation system comprises an air compensation system, an air exhaust system and a laboratory, wherein an air outlet of the air compensation system and an air inlet of the air exhaust system are communicated with the laboratory, air is connected with the air exhaust system through the air inlet of the air exhaust system after passing the laboratory so as to form a circulating ventilation system, and the air compensation system and the air exhaust system are connected with an electrical control cabinet respectively. The laboratory ventilation system is simple in structure, uniform in displacement, good in ventilation effect and capable of purifying waste gas and discharging clean air without causing pollution and is easy to implement, applicable to various types of labs and low in using cost.

Description

technical field [0001] The invention relates to the field of laboratory ventilation systems, in particular to a laboratory ventilation system. Background technique [0002] The environmental requirements of the laboratory are generally relatively high, and providing a stable environment for the experimenter is also crucial to the accuracy of the experimental data, but the air in the laboratory must be exchanged with the outside air. In addition to bringing the oxygen needed by people, bacteria and dust in the outside air will also be brought into the laboratory. At the same time, some substances produced in the laboratory will also be brought into the air during the air exchange process. These Substance may pollute the environment. The current laboratory buildings are ventilated by conventional exhaust fans, which lead the air duct to the roof of the building. The smell in the building and the laboratory is unbearable. The high-rise buildings around the exhausted gas are bo...

The current laboratory buildings are ventilated by conventional exhaust fans, which lead the air duct to the roof of the building. The smell in the building and the laboratory is unbearable. The high-rise buildings around the exhausted gas are borne by the wind. Controversy continues, and no downward exhaust is used. There are no reports of ventilation heat exchange and good ventilation without energy consumption.
