Abstract
The utility model relates to a device for absorbing harmful gases generated during chemical reactions. The heating type device for absorbing harmful gases generated during chemical reactions is provided with a supporting plate with an asbestos wire gauze in the center and legs around; a heat shield is connected to the asbestos wire gauze in the center of the supporting plate; a ring-shaped collecting tank and a tray are respectively placed on the supporting plate; the tray is placed around the outside of the collecting tank; solvents having chemical reactions with harmful gases are placed in the collecting tank; a reaction beaker is placed in the inner ring of the collecting tank, so that the outer wall of the reaction beaker can be prevented from being polluted by the solvents with strong corrosivity and later chemical reactions are not affected; a collecting shield with an adjustable exhaust pipe is put on the tray in a buckling manner. The device for absorbing harmful gases generated during chemical reactions has a simple structure, is convenient and fast to use, can effectively lower the operation complexity while promoting chemical reactions and eliminating harmful gases via corresponding chemical reactions, can promote chemical reactions and enables experiments to be operated scientifically and normatively.
Description
Technical field
the utility model relates to a kind of absorption plant, especially can promote the chemical reaction harmful gas absorption device of chemical reaction and absorption chemical reaction pernicious gas.
Background technology
at present, when the chemical reaction now carrying out in laboratory operates, often need to carry out heat treated and promote chemical reaction, in the process of chemical reaction, also supervene pernicious gas simultaneously, for example: copper and red fuming nitric acid (RFNA) react the nitrogen dioxide gas producing, thereby and laboratory conventionally selects and carry out the pernicious gas of similar nitrogen dioxide to be discharged in atmosphere in fume hood, long-term like this discharge, has just aggravated the pollution of atmosphere.
Summary of the invention
in order to solve the problem that heats and process pernicious gas in existing chemical reaction process, the utility model provides chemical reaction harmful gas absorption device, this chemical reaction harmful gas absorption device is simple in structure, convenient to use, when can promoting chemical reaction and eliminate pernicious gas by corresponding chemical reaction, can also effectively reduce the complexity of operation, and can promote chemical reaction, experimental implementation is got up more scientific and normal, be more conducive to environmental protection.
the utility model solves the technical scheme that its technical problem adopts: this chemical reaction harmful gas absorption device comprises: adjustable row tracheae, collecting hood, reaction cup, collecting pit, pallet, supporting plate, heat shield, this hot type chemical reaction harmful gas absorption device is provided with the supporting plate of a center with asbestos gauge and surrounding band supporting leg, and asbestos gauge below in supporting plate center is connected with heat shield; On supporting plate, be placed with respectively annular collecting pit and pallet, pallet is placed on collecting pit exterior circumferential, in collecting pit, be placed with for and pernicious gas carry out the solvent of chemical reaction; In collecting pit, in ring, be placed with reaction cup, so just can prevent that the outer wall of reaction cup is subject to the solvent contamination of severe corrosive, thereby affect later chemical reaction; On pallet, buckle and be placed with a collecting hood with adjustable row tracheae, when use, reaction cup is put into collecting pit, put into experimental pharmacy, buckle collecting hood, in heat shield, put into alcolhol burner chemical reaction is heated to promotion, get final product safe observation chemical experiment course of reaction, can process in time and eliminate again the pernicious gas giving off in experimentation.
the beneficial effects of the utility model, this chemical reaction harmful gas absorption device is simple in structure, convenient to use, when can promoting chemical reaction and eliminate pernicious gas by corresponding chemical reaction, can also effectively reduce the complexity of operation, and can promote chemical reaction, experimental implementation be got up more scientific and normal, more be conducive to environmental protection.
