Problems solved by technology

Acetylene consumes a lot of energy in production and use, high cost, poor quality of mechanical cleaning, slag and nodules, difficult to remove, explosive and flammable, endangering the health of workers, and serious pollution. This gas cutting technology has been around for more than 100 years. Historically, the replacement of acetylene has long been a consensus in the industry. Therefore, some domestic and foreign LPG gases are used instead of acetylene gas for welding and cutting. Poor problems, and most of the similar additives are unstable, easy to separate and contain toxic components such as xylene

preparation example Construction

[0022] Preparation of additives and mechanical cleaning gas:

[0023] During implementation, firstly pour 200# solvent oil, methanol, methyl tert-butyl ether into the stirring reactor according to the proportion and stir evenly, then iron naphthenate, n-ethane, isooctyl nitrate and acetone are used according to the proportion Put the explosion-proof pump into the stirring reactor and stir for 60 minutes, add 2,2-diethylferrocenepropane and stir for 90 minutes, then stand and age for 24 hours, enter the gas-liquid filter for filtration, and then pass the metering device The solution in the reactor is poured into a galvanized iron packaging barrel to make this type of gas additive.

[0024] It can be filled into industrial gas cylinders with a manual booster pump or an automatic metering device, or filled into a gas storage tank with a metering pump at a ratio of 0.5-1.5% to make a mixed industrial gas, or during mechanical cleaning, Add 6-12 ml of gas in the gas pipeline or mi...

Abstract

The invention discloses an efficient energy-saving additive for petroleum gas mechanical cleaning (flame cleaning) gas. The efficient energy-saving additive is mainly prepared by mixing the followingcomponents in percentage by mass: 4-8% of methyl tert-butyl ether, 8-12% of n-ethane, 1-3% of alkylferrocene, 8-12% of ethanol, 6-12% of isooctyl nitrate, 7-12% of iron naphthenate, 10-22% of acetoneand 22-55% of 200 # solvent oil. According to the efficient energy-saving additive for the petroleum gas type mechanical cleaning (flame cleaning) gas, the performance of the added petroleum gas typegas used for mechanical cleaning of steel in a steel mill comprehensively reaches and exceeds the mechanical cleaning performance level of raw petroleum gas and acetylene gas, acetylene gas and propane can be completely replaced to be used as industrial fuel gas for metal mechanical cleaning, the performance of the product exceeds that of natural gas, industrial propane and similar additives on the market, and the product has a wide application prospect and is a breakthrough of industrial gas in the industrial field of China.

Description

technical field [0001] The invention belongs to the field of mechanical cleaning gas, and in particular relates to a high-efficiency energy-saving additive for petroleum gas mechanical cleaning (flame cleaning) gas. Background technique [0002] With the rapid development of my country's industrial economy, the social demand for metal gas cutting processing is increasing. At present, the traditional method of oxygen-acetylene mechanical cleaning is widely used in metal gas cutting processing in my country. Acetylene consumes a lot of energy in production and use, high cost, poor quality of mechanical cleaning, slag and nodules, difficult to remove, explosive and flammable, endangering the health of workers, and serious pollution. This gas cutting technology has been around for more than 100 years. Historically, the replacement of acetylene has long been a consensus in the industry. Therefore, some domestic and foreign LPG gases are used instead of acetylene gas for welding ...
