Abstract

The invention provides a preparation method of metal cutting gas for natural gas. A chemical additive is developed according to the property of natural gas, wherein the additive has special functions, such as catalysis, oxidation, polymerization inhibition, combustion-supporting and the like on natural gas; and when the additive is added into gas-phase or liquid-phase natural gas, the flame frequency of natural gas in the combustion state can be changed, the combustion temperature of natural gas is raised, and more heat energy released by natural gas can be micronized. The additive consists of a plurality of light hydrocarbon chemical raw materials such as acetone, ethenone, glycol and the like, does not contain potassium permanganate, hydrogen peroxide and the like, is harmless to human bodies, is non-corrosive for relevant equipment, is free from the problems of crystallization, blockage and the like, and is fully accordant with the national provisions and requirements on metal welding cutting gas additives. The additive has a low boiling point, is easy to gasify, is naturally fused with natural gas after being added into the natural gas according to a certain proportion, can raise the combustion temperature of natural gas in oxygen to over 3,300 DEG C, and can fully meet hot machining requirements on metal cutting and the like.

Description

1. Technical field: [0001] The invention relates to a preparation method of natural gas metal cutting gas, which belongs to the field of industrial gas. 2. Technical background: [0002] The traditional acetylene gas has been used for hundreds of years, and it can be called the "leader" of the world's industrial gas. It has played an important role in the world's industrial construction. Damage to resources, pollute the environment, and endanger the health of operators, so all countries in the world are actively researching and developing new industrial gases. In some advanced countries, propylene, propane, liquefied petroleum gas and other additives are used to formulate new industrial gas, which has replaced 70% of the acetylene gas market and achieved good results. [0003] As early as 1995, the Chinese government announced that it would no longer approve new construction and expansion of acetylene gas production plants. During the "Eighth Five-Year Plan" period, the St...
