Description

The controlled generating means of hydrogen detonation

Technical field

The utility model relates to a kind of improvement of chemical experimental unit, the controlled generating means of specifically a kind of hydrogen detonation.

Background technology

In high school chemistry teaching; the test of water and sodium reaction generation hydrogen is done in the capital; method in the teaching material is that sodium is fixed on the pin; lid goes into to adorn in the plastic bottle of water then; reaction finishes; plastics spout is shifted near alcolhol burner flame, and the generation with checking hydrogen produces detonation simultaneously; explosion hazard with checking hydrogen; its weak point is: hydrogen is grasped than being difficult for Air mixing, complicated operating process, and experiment effect is not good; owing to there is not protective device; when detonation, if the vessel explosion causes the danger of hurting sb.'s feelings easily.

Summary of the invention

The purpose of this utility model is to provide a kind of operation simple in structure, easy to use, easy, can observe entire reaction course, improves the detonation effect, the controlled generating means of the non-hazardous hydrogen detonation of safety.

In order to reach above purpose, the technical scheme that the utility model adopted is: the controlled generating means of this hydrogen detonation, constitute by reactor shell, the inside of reactor shell is reaction chamber, it is characterized in that on the sidewall of reactor shell, being provided with water injection pipe and the sodium grain pipe of packing into, be provided with the hydrogen effuser in the upper end of reactor shell, the hydrogen effuser is connected with the top of reaction chamber, the detonation case is fixed in upper end in reactor shell by support, the upper end of hydrogen effuser is fixed on the bottom of detonation case, the sidewall of detonation case is provided with through hole, spark generator in the chamber of detonation case, fixing on the diapire, piezo-electric device is fixed on the upper face of reactor shell, and spark generator is connected with piezo-electric device by lead.

The utility model is also implemented by following measure: described hydrogen effuser is provided with hydrogen control valve, is provided with plug at pack into the oral area of pipe of sodium grain, is provided with valve on water injection pipe.

The beneficial effects of the utility model are: operation simple in structure, easy to use, easy, can observe entire reaction course, and the detonation test effect of generation is good, and can the damage test apparatus, can not produce danger simultaneously, has improved students'interest in learning.

The specific embodiment

Make the utility model with reference to accompanying drawing 1, the controlled generating means of this hydrogen detonation, constitute by reactor shell 1, the inside of reactor shell 1 is reaction chamber 2, it is characterized in that on the sidewall of reactor shell 1, being provided with water injection pipe 4 and sodium grain pack into the pipe 3, the sodium grain 3 is put into reaction chamber 2 from the sodium grain pipe of packing into, water is poured reaction chamber 2 into from water injection pipe 5, make water and sodium grain in reaction chamber 2, produce reaction, the hydrogen that generates accumulates in the top of reaction chamber 2, be provided with hydrogen effuser 5 in the upper end of reactor shell 1, hydrogen effuser 5 is connected with the top of reaction chamber 2, detonation case 7 is fixed in upper end in reactor shell 1 by support, the upper end of hydrogen effuser 5 is fixed on the bottom of detonation case 7, the sidewall of detonation case 7 is provided with through hole 8, so that air can enter in the detonation case 7 from through hole 8, mix with hydrogen, spark generator 10 in the chamber of detonation case 7, fixing on the diapire, piezo-electric device 9 is fixed on the upper face of reactor shell 1, spark generator 10 is connected with piezo-electric device 9 by lead, can make spark generator 10 produce spark by pushing piezo-electric device 9, light hydrogen and Air mixing gas in the detonation case 7, thereby the generation detonation reaches the experiment effect of expection.

Described hydrogen effuser 5 is provided with hydrogen control valve 6, so that hydrogen flows in the detonation case 7, close hydrogen control valve 6 again, the back tempering prevents to light a fire, injury response device housing 1, be provided with plug at sodium grain pipe 3 the oral area of packing into, so that after putting into the sodium grain, the timely jam-pack sodium grain pipe 3 of packing into, prevent hydrogen leak, on water injection pipe 4, be provided with valve, so that after in reaction chamber 2, adding entry, can timely valve-off.

During use, add water by water injection pipe 4, valve-off earlier, pack into by the sodium grain and manage 3 interpolation sodium grains, the jam-pack plug reacts sodium grain and water in reaction chamber 2, the hydrogen that generates accumulates in the top in the reaction chamber 2, opens hydrogen control valve 6, and hydrogen enters in the detonation case 7, close hydrogen control valve 6, after hydrogen and air are mixed, push piezo-electric device 9, make spark generator 10 sparkings, thereby light mist, detonation takes place.
