Abstract
PURPOSE: A ventilating device which consists in positioning a porous layer contg. a specific gasifying agent for oil fume in the flow passage of the room air to be exhausted to the room outside and which has a function of exhausting the room air to the room outside and has a function of self-cleaning in combination.
CONSTITUTION: As the above-described gasifying agent, oxides of one or more kinds of A) oxides of periodic table 1A or 2A group (e.g.; CaO, Na2O), B) compound shown by the formula, and C) oxides of Ti, Fe, Ni, Co, Cr, Cr, Ag, are used. The granules of the alumina cement contg. essentially, for example, CaSiO2 and CaAl2O3 are used as said gasifying agent. Next, a hardening assistant and a filler are added to these granules and the mixture is granulation molded, after which the granules are packed in a wire net, whereby the filter is made. This filter is disposed in the room side of a ventilation fan and a sheathed heater is disposed in the filter surface to permit temperature controlling. The oil component adhered to this ventilating device is decomposed by supplying the power to the sheathed heater, whereby the filter is perfectly cleaned.
