Description

Experiment of Gas Proliferation device

Technical field

A kind of Experiment of Gas Proliferation device, belongs to physics teaching, experimental apparatus.

Background technology

In people education publishing house, Ministry of Education's authorization, in the 3rd page present, ninth grade compulsory education textbook physics textbook, the diffusion experiment of nitrogen dioxide gas does like this: on the bottle being filled with rufous nitrogen dioxide gas, back-off old soldi, make two bottlenecks relative, between separate with one piece of glass plate; After taking out glass plate, what change can be there is? the density ratio air of nitrogen dioxide is large, can it enter in bottle above and go? this experimental technique, maximum advantage is exactly directly perceived; But maximum shortcoming is exactly: have nitrogen dioxide gas to be discharged in air the pollution causing air in experimentation, this shows following several respects:

1, in order to collect the nitrogen dioxide gas of one bottle of experiment, must produce with certain device, collecting; When producing nitrogen dioxide gas, due to the defect of the device for making of experiment, fail to come according to actual needs quantitatively to produce nitrogen dioxide gas, obtained unnecessary nitrogen dioxide gas, due to part Experiment, personnel dislike trouble, quality is low, the impact of the factor such as to lack a sense of responsibility, and can not get reasonably process and has just directly been discharged in air;

2, when collecting nitrogen dioxide gas, because the collection method used is upwards air-discharging method, when collecting with common gas bottle, necessarily there is nitrogen dioxide gas to be more or less discharged in air;

3, cover nitrogen dioxide gas in gas bottle in storage with glass sheet, take from laboratory the transportations such as classroom, because the result of diffusion also has some can escape in air more or less;

4, after finishing the diffusion experiment of nitrogen dioxide gas, during cleaning instrument, some teachers dislike trouble, and do not do any process, and just direct being directly discharged in air by nitrogen dioxide gas has been gone;

In the reason of above nitrogen dioxide pollution air, there is the reason of the existing defects of the gathering-device of nitrogen dioxide gas own, also have peopleware, the reason that sense of responsibility etc. are artificial; Also has the reason of experimental program existing defects.

Utility model content

In order to address these problems, I devises a kind of Experiment of Gas Proliferation device, uses this Experiment of Gas Proliferation device to have effect clearly:

1, this Experiment of Gas Proliferation device, experiment is omnidistance, and the diffusion gas in the experiment that can pollute air is in closed space all the time, really can accomplish zero-emission, no pollution;

2, this Experiment of Gas Proliferation device is simple, and intuitively, easily make, cost is low, and safety is easy to operate, and teachers and students gladly use, and easily promotes, and is of great importance to the pollution of ACTIVE CONTROL from experimental teaching aspect.

Being constructed as follows of Experiment of Gas Proliferation device: be the little glass ring of welding at the bottom of the short test tube of 18mm diameter, after cooling, glass ring is fastened through the silkworm gut of glass bend pipe, the exit of silkworm gut needs good seal, be the test tube of 7mm by it with going the diameter at the end to be the test tube of 20mm and diameter, single hole rubber plug, a liquid seal device made by sealing liquid, then by this liquid seal device and large single hole rubber plug, the large double-hole rubber plug inserting curved glass pipe in advance, single port gas bottle, both sides all with piston, three mouthfuls of gas bottles that grass tube is connected couple together; Namely this Experiment of Gas Proliferation device is that piston is respectively with in both sides, three mouthfuls of gas bottles of conduit by a; B, with the liquid seal device that the test tube of different-diameter is processed into, these liquid seal device two ends are all fixed on large rubber plug, and be connected with other experimental apparatuss by large rubber plug, sealing liquid used be can not diffusion gas in dissolution experiment can not with the liquid of the diffusion gas generation chemical reaction in experiment or slurry, liquid seal device can control as opening or closing with through the silkworm gut of glass bend piping at glass ring; C, single port gas bottle three part is formed; During use, open the piston on three mouthfuls of gas bottle left sides, the piston on the right opened and is connected with the Drexel bottle of process tail gas, after collecting the diffusion gas of full one bottle of experiment, closing left and right piston, when doing gas diffusion lecture experiment, with pulling silkworm gut just; Experimental implementation is easy, safety, and experiment whole process can accomplish zero-emission, no pollution.

Diagram manufacturing process:

The first step, respectively bores a hole on the shoulder both sides of a 500ml gas bottle, then carries out simple glass processing, and like this, single port gas bottle originally just becomes three mouthfuls of gas bottles;

Second step, respectively fills in the single hole rubber plug of band grass tube on these gas bottle both sides;

3rd step, couples together the grass tube emulsion tube on the grass tube of band piston and single hole rubber plug;

4th step, the test tube being 20mm diameter removes bottom test tube as required, and large single hole rubber plug is inserted in one end, and the other end also inserts the large double-hole rubber plug that is inserted curved glass pipe in advance;

5th step, be that to insert diameter be the Boiling tube of 20mm for the little single hole rubber plug of the small test tube of 7mm by inserting diameter in advance, erect, pour into can not diffusion gas in dissolution experiment can not with the liquid of the diffusion gas generation chemical reaction in experiment or slurry;

6th step is the little glass ring of welding one at the bottom of the short test tube of 18mm at diameter, and after cooling, glass ring is fastened through the silkworm gut of glass bend pipe, the exit of silkworm gut needs good seal;

7th step, large single hole rubber plug is filled in three mouthfuls of gas bottles, and large double-hole rubber plug fills in single port gas bottle; So far, Experiment of Gas Proliferation device has just been made; As can be seen here, this Experiment of Gas Proliferation device is by a, the three mouthful gas bottles of both sides respectively with piston, conduit; B, with the liquid seal device that the test tube of different-diameter is processed into, these liquid seal device two ends are all fixed on large rubber plug, and be connected with other experimental apparatuss by large rubber plug, sealing liquid used be can not diffusion gas in dissolution experiment can not with the liquid of the diffusion gas generation chemical reaction in experiment or slurry, liquid seal device can control as opening or closing with through the silkworm gut of glass bend piping at glass ring; C, single port gas bottle three part is formed.
