Laboratory ventilating system

Abstract

The invention provides a laboratory ventilating system and relates to the technical field of laboratory equipment. The laboratory ventilating system comprises an air exhausting structure and an air supplying structure, wherein the air exhausting structure and the air supplying structure are distributed on the two sides of a laboratory; the air exhausting structure comprises a plurality of branchedair exhausting pipes and a drying air exhausting pipe; the branched air exhausting pipes communicate with the drying air exhausting pipe; negative pressure fans are mounted in the branched air exhausting pipes; a using end communicates to the bottom ends of the branched air exhausting pipes; the drying air exhausting pipe communicates with the air inlet of a first fan box; the air outlet of the first fan box communicates with a waste gas treatment tower; the air supplying structure comprises a plurality of branched air supplying pipes and a drying air supplying pipe; the branched air supplying pipes communicate with the drying air supplying pipe; an air supplying end communicates with the bottom ends of the branched air supplying pipes; and the drying air supplying pipe communicates withthe air outlet of a second fan box. The laboratory ventilating system solves the technical problems that the existing laboratory ventilating system enables the temperature of a laboratory to be lowerin winter and cannot flexibly supplement the indoor air.

Description

technical field [0001] The invention relates to the technical field of laboratory equipment, in particular to a laboratory ventilation system. Background technique [0002] The experimental ventilation system is widely used in a series of research places such as hospitals, schools, and various research institutes. In the laboratory, due to the use of various chemical substances, it often causes air pollution in the laboratory. Some substances not only smell bad , but also harmful to health. In order to create a healthy and safe working environment, the laboratory ventilation system can meet the requirements of hospitals and schools and meet the above requirements. [0003] The existing laboratory ventilation system realizes the rapid replacement of the gas in the laboratory through quantitative air supply and exhaust, but at the same time, due to the relatively fast air flow, the temperature in the laboratory is relatively low in winter, which affects The working environmen...
