The method for formulating of described cutting-welding gas is: it comprises following three steps:
A. additive preparation mixed solution: will drop in the mixing tank by the ready additive raw material of certain weight ratio earlier, and under sealed state uniform mixing; For emitting mixed solution, should in mixing tank, increase air pressure;
B. take out additive mixed liquor: charge rifle with additive and from mixing tank, take out certain quantity of additive;
C. additive mixes with liquefied gas: additive is charged the certain quantity of additive mixed solution injects a certain amount of liquefied gas bottle in the rifle, promptly obtain cutting-welding gas of the present invention.
In the cutting-welding gas method for formulating of the invention described above, the air pressure that adds in the described mixing tank is to be no more than 6 kilograms of atmospheric ratio pressurizations in 10 kilograms of additive mixed liquor pressurizations; The gas that adds can be natural air; When injecting additive mixed liquor, be the ratio injection of injecting 40-80 gram additive mixed liquor in 6 kilograms of liquefied gas, i.e. 6,000: 40～80 ratios.
In the cutting-welding gas method for formulating, during the additive preparation mixed solution, the raw material that drops in the additive mixing tank is to drop into solid calcium chloride and potassium permanganate by elder generation, and the ethanol that liquid is dropped in the back carries out in proper order; The method that raw material is mixed is to shake mixing.
The advantage of cutting-welding gas of the present invention, can learn with its component:
Based on propane or/and the liquefied gas of the hydrocarbons of butane, main raw material is from petrochemical complex, be refinery, oil field, petroleum chemical plant, contain propane or/and butane in the raw material of liquefied gas, can also propylene be arranged or/and the butylene hydrocarbon polymer, be characterized in that a. easy firing is because of its composition is an oil liquefied gas; B. boiling point of liquid is low, can gasify rapidly; C. have lower flash-point and burning-point; D. the fuel value height is higher by 30% than carbide acetylene gas; E. cost is low: about the per kilogram raw material is made cutting-welding gas of the present invention and is at half than the acetylene gas that by calcium carbide, acetone is raw material production.
2. the advantage brought of additive:
A. Calcium Chloride Powder Anhydrous CaCl
2As gas dryer, can make antifogging agent, defrost, molten ice has antifreeze function.
B. potassium permanganate is used for organic synthesis, and gas heating value is increased.
C. ethanol can make substance dissolves be subjected to acute coldly also can not condense, and calorific value is increased;
Cutting-welding gas production site of the present invention is answered Fire Hazard Area, prevents any behavior that causes spark, and for example electrical equipment sparking is knocked sparking, naked light etc.; Also should forbid disorderly to fall raffinate.
The embodiment of the invention:
1. three embodiment of additive mixed liquor preparation:
1.1. with 5 gram calcium chloride, 5 gram potassium permanganate inputs are mixed in the flow container, add 5 kilograms of ethanol then, shake tank body after tank valve is closed, and make mixing of materials even; From the pressurizing valve of tank body, be pressed into 3 kilograms normal atmosphere again, close tank body then.Normally pressurize in the additive getting so that take out additive, when not taking out additive, in the tank body to keep normal pressure to be advisable.
