Abstract
The utility model relates to a new type gas generator, which is the improvement of the prior gas generator. A reaction chamber (4) is communicated with an acid storing chamber (2) through a communicating pipe (3), and the purpose of controlling the reaction can be achieved by making use of the gas pressure of the gas generated by the reaction. The utility model is applicable to the experiments of preparing the type one gas in the chemical classroom teaching, such as the hydrogen, the carbon dioxide and the hydrogen sulfide. The start and the end of the reaction can be controlled at any time, and the gas can be prepared conveniently and rapidly. The limited classroom time can be utilized effectively, and the teaching efficiency can be improved. The utility model is made of apparent material, which is convenient for the students to observe the reaction principle.
Description
One, technical field
The utility model relates to a kind of high school chemistry teaching instrument, can produce these type of gases such as hydrogen, carbon dioxide, hydrogen sulfide apace on relevant chemical test class.So long as utilize solid matter and liquid substance to produce gas, can use this utensil without heating.
Two, background technology
Recommend the chemistry teaching instrument of use on the chemical textbook---kipp gas generator (teaching 51 pages of edition junior high school chemical textbooks) with reference to 02 year people, in China's chemistry experiment, continued to use for many years, its principle is in common knowledge by many personages that are familiar with chemical experiment, being applicable in experimental teaching that solid-state liquid meets not heat produces gas, its advantage is that reaction is taken place at any time, reaction is ended at any time, it is little that its shortcoming provides gas pressure, sluggish, broken easily, safety coefficient is little.
Three, summary of the invention
I am according to the experience with students of decades, reality in conjunction with chemical experiment, the automatic pneumatic gas generator of design invention, be to utilize modern new material---transparent plastic, be designed to the closed container that two bottoms are interconnected, a container is as reactor, another container is used for storing up acid solution and compressed air, the net bucket of containing solid matter is set in reaction vessel, and the process of carrying out behind the adding solid matter is: generated reactive gas, and---air pressure increases on the liquid level, and---acid solution flows into the interior pressure of acid-storing barrel---air is compressed---and increases.When air pressure acquired a certain degree, reaction stopped voluntarily.This automatic pneumatic gas generator not only has the advantage of kipp gas generator, but also has following advantage: blow off pressure is big, the flow velocity height; Test speed is fast, the efficient height; Medicine utilization rate height; Safe and reliable, be beneficial to environmental protection.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment
With reference to accompanying drawing the utility model is further described.
Seal cover 1 spiral cover on acid storage chamber 2, is guaranteed acid storage chamber 2 good seals; Open the top cover 9 on reative cell 4 tops, the solution of the participating in reaction top from reative cell 4 is added up to the position of liquid level near upper limit label 8, have the solution of a small amount of participation reaction to flow in the acid storage chamber 2 by communicating pipes 3; Plastic wire bucket 5 is taken off from top cover 9 rotations of having opened, in plastic wire bucket 5, add the granular solids reactant that needs to participate in reaction, then 5 rotations of plastic wire bucket are fixed on the top cover 9, and top cover 9 rotation that will fix plastic wire bucket 5 is fixed on the top of reative cell 4, screws to guarantee reative cell 4 good seals.Reaction beginning, the pressure of generated reactive gas force the solution of participating in reaction in the reative cell 4 to flow into acid storage chamber 2 by communicating pipe 3, and the solution of participating in reaction in reative cell 4 separates with plastic wire bucket 5 fully, and reaction stops.
During using gases, open air bleeding valve 7, gas discharges from blast pipe 6, can collect the gas that reaction produces by blast pipe 6; After the gas that stores in the reative cell 4 discharged from blast pipe 6, reative cell 4 internal gas pressures reduced, and the solution of participation reaction contacts with the plastic wire bucket 5 interior solid matters of participating in reaction by flowing into communicating pipe 3 in the reative cell 4 in the acid storage chamber 2, and reaction continues to carry out.Getting gas finishes, close air bleeding valve 7, the reaction in the reative cell 4 is proceeded, and the gas that reaction produces forces the solution of participating in reaction to flow into acid storage chamber 2 by communicating pipe 3 once more, when the solution of participating in reaction in the reative cell 4 separated fully with plastic wire bucket 5, reaction stopped automatically.
The utility model can make reaction take place at any time, ends at any time; Provide gas more, gas pressure is bigger.
The utility model is a material with high strength, acidproof, transparent plastics, is difficult for breaking, and has improved the safety coefficient in experimentation greatly.
