Problems solved by technology

[0003] Most of the current industrial welding and cutting use a single acetylene gas for cutting. Acetylene is commonly known as wind coal or calcium carbide gas. It is the smallest member of alkyne compounds. It is mainly used for industrial purposes, especially for welding metals. Acetylene is the best choice. However, due to the high cost of raw materials and the great safety hazards of production and storage, industrial acetylene is a high-emission and high-polluting substance, which will have a certain impact on the environment and occupational health. The safety conditions of the production site are very high, which is not convenient Construction requires a large investment, therefore, there is an urgent need for a mixed welding and cutting gas preparation method to solve the above problems

preparation example Construction

[0023] A method for preparing mixed welding and cutting gas, comprising acetylene gas, propane, hydrogen peroxide, sodium bicarbonate, polymerized iron solution, and petroleum liquefied gas, wherein the mass ratio of the above-mentioned various components is: acetylene gas 50% to 75%, Propane 20%~40%, hydrogen peroxide 0.1%~1%, sodium bicarbonate 0.5%~1%, polymerized iron solution 0.2%~0.7%, petroleum liquefied gas 5%~10%, the specific operation steps are as follows:

[0024] S1: Mix sodium bicarbonate and hydrogen peroxide evenly, make it fully dissolved to obtain a mixed solution, and make gas and liquid mix gas-liquid;

[0025] S2: adding the polymerized iron solution to the mixed solution, and mixing evenly to obtain a new mixture;

[0026] S3: Inject an appropriate amount of the new mixture into an empty acetylene cylinder, and then place the cylinder on the cylinder filling bus;

[0027] S4: Fill propane, liquefied petroleum gas, and acetylene gas in proportion to the a...

Embodiment 1

[0030] Take 0.7 parts of hydrogen peroxide and 0.8 parts of sodium bicarbonate and mix them evenly, so that they are fully dissolved to obtain a mixed solution, so that the gas and the liquid are mixed in gas and liquid; 0.5 parts of polymeric iron solution is added to the mixed solution, and the mixture is uniformly mixed to obtain a new mixture; An appropriate amount of the new mixture is injected into the empty acetylene gas cylinder, and then the gas cylinder is placed in the gas cylinder filling manifold; 20 parts of propane, 8 parts of petroleum liquefied gas, and 60 parts of acetylene gas are fully mixed in the above-mentioned acetylene gas cylinder; preparation and mixing are complete After inspection, it will be put into storage after passing the test.

Embodiment 2

[0032] Take 1 part of hydrogen peroxide and 0.5 part of sodium bicarbonate and mix them evenly, so that they are fully dissolved to obtain a mixed solution, and the gas and the liquid are mixed with gas and liquid; 0.5 part of polymeric iron solution is added to the mixed solution, and the mixture is uniformly mixed to obtain a new mixture; Inject an appropriate amount of new mixture into an empty acetylene cylinder, then place the cylinder on the cylinder filling manifold; mix 25 parts of propane, 10 parts of petroleum liquefied gas, and 53 parts of acetylene gas into the above-mentioned acetylene cylinder; prepare and mix completely After inspection, it will be put into storage after passing the test.
