Description
Technical field
The present invention relates to the vent cabinet that the physical and chemical experiment chamber is used, relate in particular to a kind of waste gas circulation and use vent cabinet, belong to laboratory equipment.
Background technology
Regular meeting produces some pernicious gases when doing physical and chemical experiment, comes to harm for avoiding human body and equipment, and people are extracted into pernicious gas outdoor with the vent cabinet that blower fan is housed usually.Because rate of air circulation is big, to such an extent as to air-conditioning temperature-reducing can not be used in south in full summer, physical and chemical experiment chamber, can not use heating installation heating in the north in midwinter, the temperature in the laboratory can not be regulated, and working environment can not get improving.
Summary of the invention
The objective of the invention is to propose a kind of laboratory rate of air circulation that can make and greatly lower, thereby make the adjustment in the laboratory become possible waste gas circulation use vent cabinet in order to solve the deficiency that the above-mentioned background technology exists.
The technical scheme that the present invention provides for addressing the above problem is: a kind of waste gas circulation is used vent cabinet, comprise the vent cabinet cabinet, circulating fan is housed in cabinet, it is characterized in that this vent cabinet also is provided with the Rose Box that waste gas is handled, the air inducing inlet of described circulating fan links to each other with the air inlet of Rose Box, and the air outlet of circulating fan links to each other with the Rose Box air outlet by work top; Described vent cabinet cabinet is a full-closed structure, and the transparent observing panel is equipped with in its front, has hand hole on the transparent observing panel, and work gloves is housed on hand hole.
In such scheme, described Rose Box can place cabinet internal upper part, bottom or outside.Circulating fan also can place cabinet internal upper part or bottom according to the installation site of Rose Box.
In such scheme, the tank wall of described Rose Box is made of inside and outside boxboard and the insulation material that is clipped in wherein, about Rose Box, have air inlet or gas outlet on the tank wall at two ends, in Rose Box, be provided with the multiple filtration sorbing material, be provided with heating element heater between the adjacent two layers sorbing material, the switchboard that can be respectively air inlet and gas outlet be opened and closed is housed respectively at the air inlet of Rose Box and place, gas outlet, and this switchboard links to each other with reducing motor by adpting flange.
In such scheme, be provided with the outer exhaust blower outside cabinet in the described cabinet, so that the operating space is in the micro-vacuum state.
In such scheme, described transparent observing panel adopts glass, its both sides are fixed with the glass clamp bar, the glass clamp bar places in the glass sliver of vertical layout, can move up and down along the glass sliver, is provided with the lifting device of being made up of support, pulley, steel wire rope and balancing weight in the cabinet upper end, wherein, steel wire rope is walked around pulley, and the one end links to each other with the glass clamp bar, and the other end links to each other with balancing weight.This is set in order easily to mention the transparent observing panel.
Waste gas circulation of the present invention uses vent cabinet almost completely to be enclosed in the operating space in the cabinet, during work, the present invention handles pernicious gas by the filtering adsorbing material in the Rose Box under the effect of circulating fan, harmful substance is stayed on the sorbing material, waste gas can be reused.After sorbing material adsorbs a certain amount of harmful substance, just can close switchboard by reducing motor, adpting flange, opening heating element heater then will filter the temperature inside the box and be heated to 120-180 ℃, open outer exhaust blower again, the interior air of Rose Box is flowed, handle thereby sorbing material is carried out desorption, sorbing material is just reusable.
Excessive for preventing pernicious gas, the present invention has hand hole on the transparent observing panel, work gloves is housed on hand hole, and the staff need not open the transparent observing panel and be convenient to operation when operation, and the present invention is equipped with outer exhaust blower again can make leakage rate drop to minimum level.
The present invention becomes the course of work of the air inlet-work-generation waste gas of common ventilation blower-efflux the course of work of work-generation waste gas-exhaust-gas treatment-recycle.It is simple in structure, and is easy to use, pernicious gas can be controlled in the minimum scope to handle, very little to air ambient in the laboratory and temperature effect, has improved the working environment of laboratory worker greatly.
