Problems solved by technology

At present, most of the fume hoods used in laboratories are steel-wood or aluminum-wood structures. Toxic, harmful and corrosive gases are attached to the joints of steel-wood or aluminum-wood, which corrodes and damages the components of the fume hood, seriously affecting the ventilation performance and use of the fume hood. life

Abstract

The invention discloses a floor type ventilation cabinet. The floor type ventilation cabinet comprises a cabinet body and a working table in the cabinet body; a front cabinet door of the cabinet body is an outward-pulling type double-door glass cabinet door; a waste gas collecting device is arranged at the top end of the cabinet body; the waste gas collecting device comprises a waste gas collecting cover, a filter bin and a heat exchange bin, wherein the filter bin is connected to the waste gas collecting cover, and the heat exchange bin is connected to the filter bin; the heat exchange bin is connected to an air suction pipeline; and the air suction pipeline is connected to an induced draft fan. The floor type ventilation cabinet is simple in structure, capable of effectively absorbing and filtering harmful gas and convenient to replace and maintain.

Description

technical field [0001] The present invention relates to laboratory fume hoods. Background technique [0002] The most important function of the fume hood is to discharge the harmful gas generated in the experiment and protect the health of the experimenters. [0003] In the laboratory, various harmful gases, odors, moisture, and flammable, explosive, and corrosive substances are produced during experimental operations. Fume hoods should be used nearby. In the past, the number of fume hoods used was relatively small, and they were only used in experiments with particularly harmful and dangerous gases and large amounts of heat. The fume hood is only responsible for the auxiliary function of the experimental bench. Taking into account the improvement of the experimental environment, the experiments carried out on the test bench are gradually transferred to the fume hood, which requires the most suitable functions for the use of equipment in the fume hood. In particular, most...
