Air blowing type fast and environment-friendly gas generator

Abstract

The invention relates to an air blowing type fast and environment-friendly gas generator, which is adaptive to preparing gas by means of insoluble solid and liquid at normal temperature. According to the air blowing type fast and environment-friendly gas generator, a tubular vertical generator is inserted on a seat-type reservoir to form a vertical communicating device; an air blowing ball (used in a blood-pressure meter) is communicated with the communicating device through a Y-shaped tube and a latex tube; the solid is arranged on a porcelain multi-pore baffle plate in the generator, and the liquid is injected into the reservoir; a porous piston cover on the rotary tubular vertical generator is used for determining air inflation routes, the internal pressure is increased when the reservoir is inflated by air, the liquid rises to contact with the solid, and a reaction occurs; and an air valve turn knob on the air blowing ball is loosened, the air is released, the liquid flows back to the reservoir, and the reaction is stopped. If the prepared gas is the toxic gas, the generator is inflated by the air when an experiment is finished, and the toxic residual gas in the generator is exhausted and is absorbed by absorption liquid, so that the zero discharge of the toxic gas is realized. The air blowing type fast and environment-friendly gas generator has fast, environment-friendly, safe and convenient gas preparation effects.

Description

technical field [0001] The invention relates to a gas generating device for producing gas from insoluble solid reactant and liquid reactant at normal temperature without heating. It has fast control, easy to use and take out, saving and environmental protection, safe and reliable gas production effect. Background technique [0002] Commonly known Kipp generators are used in laboratories to produce gases (such as figure 1 ), which is composed of a spherical long-necked funnel ( figure 1 Medium 1), flat-bottomed gourd-shaped container ( figure 1 2) and a guide tube with a plunger ( figure 1 Middle 3) consists of three parts. The solid reactant is put into the upper chamber from the vent of the container, and the liquid reactant is injected from the funnel mouth. When in use, open the piston on the air guide tube, the liquid in the spherical long-necked funnel enters the container and contacts with the solid reactant, at this time the reaction occurs and gas is gener...

Problems solved by technology

It is not difficult to find that there are many disadvantages in using the known Kip generator to produce gas: 1. Inconvenient operation and easy mistakes: using the Kip generator is not only inconvenient to operate when loading solid medicines, but also solid reactants during use It is easy to fall into the lower chamber of the container. If the solid medicine falls into the lower chamber or there is loose air leakage at the joint between the funnel and the container mouth, and when the medicine needs to be added during the experiment, the medicine must be taken out and reinstalled, which is very troublesome; when the gas production is stopped , after the piston is closed, there may be air leakage or bursting of the container due to excessive gas pressure, resulting in experimental failure or even a safety accident

2. Waste of medicines and slow control: starting from the stability of the equipment, the gourd-shaped container of the Kipp generator is larger and requires more liquid reactants; and to stop the reaction, a certain amount of medicine must be consumed after closing the piston. Generate residual gas to generate a certain pressure and press the liquid back into the funnel, which of course leads to waste of medicines and slow control

3. No environmental protection function: After the experiment, when washing the instrument, the residual gas in the Kippo generator can only be discharged directly into the air. If the gas produced is toxic gas (such as hydrogen sulfide, etc.), it will inevitably cause environmental pollution and cause environmental pollution. Against the concept of green environmental protection
