Abstract

The air supplement and exhaust cabinet comprises an exhaust cabinet body and a visual window, a cavity with an opening in the front side is formed in the exhaust cabinet body, a workbench is arranged on the lower portion of the cavity, a static pressure box capable of supplying air into the cavity is arranged at the bottom of the workbench, a top plate is arranged at the top of the exhaust cabinet body, and side plates are arranged on the two sides of the exhaust cabinet body. Upright structures are connected to the front ends of the side plates; the exhaust cabinet body further comprises an air wing structure which is arranged on the front lower portion of the cavity and connected with the static pressure box. The static pressure box comprises a first air supply channel and a second air supply channel; the air wing structure is provided with an air inlet and an air outlet, the air inlet communicates with the first air supply channel, and the air outlet communicates with the cavity. The stand column structure internally comprises a stand column inner cavity, an air supplementing groove is formed in the side, close to the cavity, of the stand column structure, and the second air supply channel communicates with the stand column inner cavity which communicates with the air supplementing groove. Therefore, the air supplement effect is improved, the stability of airflow in the exhaust cabinet is ensured, a high-power fan is not needed, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of laboratory air exhaust equipment, in particular to a supplementary air exhaust cabinet. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Laboratory ventilation is an integral part of laboratory design. In order to prevent laboratory workers from inhaling or ingesting some toxic, pathogenic or unknown toxic chemicals and organisms, there should be good ventilation in the laboratory. To prevent the absorption of some vapours, gases and particulates (smoke, soot, dust and aerosols), pollutants must be removed by fume hoods, fume hoods or local ventilation. [0004] The fume hood is the most commonly used local exhaust equipment in the laboratory. Generally speaking, the top of the fume hood is equipped with an exhaust device, which can discharge toxic and harmful gases to the out...
