The invention discloses a cleanable fume cupboard applied to a lab or a special place and belongs to the field of lab venting equipment. The fume cupboard comprises a framework body, a transparent plate is arranged on the lateral side of the framework body, and a filtering device is further arranged at the top of the framework body; the filtering device comprises a device body, and an air inlet and an air outlet are formed in the device body; an activated carbon filtering layer and a fan are arranged in the device body, and the activated carbon filtering layer and the fan are both arranged between the air inlet and the air outlet; and differential pressure alarms are further arranged on the air inlet and the air outlet, and the differential pressure alarms and the fan are all connected to a controlling module. Chemical substance volatilization is controlled in the framework body, and experimenters can observe experiment phenomena through the transparent place; gas in the framework body can be pumped out through the fan and then be filtered by the activated carbon filtering layer to be exhausted, and gas is prevented from directly volatizing in air in the lab; and accordingly, the ventilating and filtering difficulty and the power are reduced. The cleanable fume cupboard is especially suitable for being installed and applied to the labs with lower floor height.
Description
technical field [0001] The invention relates to a laboratory ventilator, more specifically, the invention mainly relates to a cleanable fume hood which can be used in laboratories or special places. Background technique [0002] In special places such as laboratories, harmful chemical substances are prone to volatilize in the air, so it is necessary to filter the air to ensure the safety of the experimenters. At present, there are various types of laboratory ventilation equipment on the market, and the structure with good filtration performance is complicated. , high purchase cost and maintenance cost, low price, low performance, poor filtering effect, can not meet the requirements of use, so it is necessary to study and improve the ventilation and filtering equipment in special places such as laboratories. Contents of the invention [0003] One of the purposes of the present invention is to address the above deficiencies, to provide a cleanable fume hood that can be u...
