Abstract
The utility model relates to an acid rain forming demonstration apparatus which is characterized in that an electric hot plate, a smoke gas cover, a pipeline, a mixing cabin, a steam generator and an alcohol burner are all fixed on a demonstration plate; the top end of the smoke gas cover above the electric hot plate is communicated with the mixing cabin through the pipeline; the pipeline in the mixing cabin is communicated with the steam generator. The utility model has the advantages of simple structure, convenient use, portability, clear demonstration, convenient observation and convenient operation. The utility model overcomes the problems of the prior art that the observation and the control of the process of forming the acid rain from burning coal are difficult, and the period is long. The utility model fills the blank of demonstrating the forming process of the acid rain in laboratories.
Description
The utility model relates to a kind of chemical teaching aid, and especially a kind of acid rain forms demonstration device.
China is a coal-fired big country, and 1,000,000,000 tons in year consumption coal enters nearly 3,000 ten thousand tons of airborne sulphuric dioxide.Because sulphuric dioxide is acidic materials, forms acid with water vapor chemical combination in air, form rain landing ground again, formed acid rain.Acid rain all causes serious harm to soil, biology, buildings and the mankind, has become global public hazards at present.In order to popularize science, protect our environment and home, since the junior middle school just to the knowledge of the relevant acid rain forming process of student explain.But existing acid rain demonstration device is very huge, and is not portable, and demonstration is difficult to observe, and effect is also not ideal enough.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, is easy to carry, and effect is obvious, and the acid rain of being convenient to operate forms demonstration device.
The purpose of this utility model is achieved in that: electric hot plate, flue gas cover, pipeline, mixed cabin, steam generator, spirit lamp all are packed on the demonstration board, the flue gas cover top of electric hot plate top also has pipeline connection one steam generator by the pipeline connection mixed cabin in the mixed cabin.
Mixed cabin also is shaped on escape pipe and leak-off pipe.
Advantage of the present utility model and good effect are:
All be packed on the demonstration board member that needs, the potpourri that adds hot coal and sulphur powder by electric hot plate, the coal that produces and the mixed gas of sulphur mix with water vapor in mixed cabin, and the globule of formation is acid rain and flows out by leak-off pipe, gets final product by the check of PH test paper again.The utility model is simple in structure, and is easy to use, is easy to carry, it is clear to demonstrate, and is convenient to observe, and is convenient to operation, overcome be difficult to being difficult in the prior art realize to observe, be difficult to hold from fire coal to the acid rain forming process, a difficult problem that the cycle is long, filled up the blank of laboratory demonstration acid rain forming process.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model embodiment is done further auspicious stating:
Be placed with the potpourri 6 of coal dust and sulphur powder on the electric hot plate 7, the top of this electric hot plate is equipped with a flue gas cover 5, the top of this flue gas cover is communicated with mixed cabin 2 by pipeline 3, and this mixed cabin also is communicated with steam generator 9 by pipeline 11, and the steam generator below is equipped with a spirit lamp 8.Mixed cabin also is shaped on escape pipe 1 and leak-off pipe 10.All available iron wire of electric hot plate, flue gas cover, pipeline, mixed cabin, steam generator, spirit lamp or adhesive tape are packed on the demonstration board 4.
In order to save cost, flue gas cover, mixed cabin can be done with the Coke bottle system, and pipeline can be made of glass tube, and steam generator can be replaced by test tube.Line seal can be sealed by the gluing row that taps into.
Using method of the present utility model is:
Steam generator injects the hot water of 1/3 volume, lights the spirit lamp heating; The potpourri of coal dust and sulphur powder is placed on the electric hot plate energising heating blends; At this moment adularescent smog rises in the potpourri, enters mixed cabin; Water vapor was also produced by steam generator and entered mixed cabin this moment; There is the globule on the mixed cabin inwall, to produce after two kinds of gases mix, flows out through leak-off pipe; Too much mixed gas is discharged by escape pipe.
