Embodiment 1

[0031] A certain unit uses pipeline natural gas on the HJZCGD-1500 cantilever type large-section flame cutting machine, and through the TANRANQIQI device with rare earth polymerization agent to make a new type of industrial gas to cut the material is P91, and the diameter specifications are 800mm, 900mm, 1150mm, 1400mm steel ingots.

[0032] Use natural gas to cut steel ingots with a diameter of 800mm, and the natural gas consumption is 9m 3 , the cost is 2.02 yuan / m 3 ×9m 3 = 18.18 yuan; using new industrial gas to cut P91 steel ingots with a diameter of 800mm, the natural gas consumption is 3m 3 , the addition amount of rare earth polymerizer is 5g / m 3 . The cost is (2.02 yuan / m 3 +0.2 yuan / g×5)×3m 3=9.06. Cost savings of 9.12 yuan.

[0033] Use natural gas to cut P91 steel ingots with a diameter of 900mm, and the natural gas consumption is 12m 3 , the cost is: 2.02 yuan / m 3 ×12m 3 = 24.24 yuan; using new industrial gas to cut P91 steel ingots with a diameter of 90...

Embodiment 2

[0045] A certain unit used new type of industrial gas on profiling flame cutting machine and semi-automatic flame cutting machine to cut steel plate with thickness of 10mm / 40mm / 50mm and material of Q550, and achieved obvious social and economic benefits. The original cutting gas used by the unit was propane gas, which was supplied by 50kg gas cylinders, with an annual consumption of more than 2,000 cylinders, and the gas cost was about 1.4 million yuan. Later, the new technology of cutting steel with new industrial gas is adopted, and the pressure of the natural gas reaction control device and the natural gas pipeline at room temperature is 0.012MPa. Compared with the cost of using bottled propane cutting gas, the cost is reduced by about 65%, and the annual economic benefit is about 900,000 yuan. The comparison of relevant technical indicators of the two gas-cut steel materials is shown in Table 1:

Embodiment 3

[0054] The specific implementation of the use of new industrial gas in the furnace heating of the vehicle bottom drying furnace of a certain unit is as follows:

[0055] The car bottom drying furnace is used for uniform temperature drying of processed parts, and its structure is composed of furnace body, trolley, heating device, control system and other parts. Combustion system: 25mm burners are selected, 5 groups are installed in total, and the natural gas consumption is 1300M 3 / h. In order to change the large consumption of natural gas, poor effective utilization rate, low flame temperature, high carbon monoxide emission, low qualified rate of workpieces, when the peak gas consumption comes, the flow of natural gas decreases, the temperature required by the kiln cannot be guaranteed, and the operation of the kiln is affected. In this situation, it is decided to adopt a new pipeline industrial gas heating and energy-saving technology. The natural gas pressure regulating dev...

Abstract

The invention relates to an application of novel pipeline industrial gas in metal cutting and kiln heating and belongs to the technical field of combustion methods of a fluid fuel. The novel industrial gas is prepared by taking pipeline natural gas as master batch and adding a rare earth polymerizing agent at a certain ratio through a TANRANOIOI reaction control device; the pressure of the pipeline natural gas is at 0.012-0.03Mpa, the pipeline natural gas is used for cutting metal, the flow of the pipeline natural gas is less than 100m<3>/h. and the volume ratio of the added rare earth polymerizing agent is 0.05-0.2%; the working pressure of oxygen is at 0.1-0.3Mpa; flame is not extinguished or tempered within 10 seconds at a 10m/s vertical air speed; when the novel pipeline industrial gas is used for heating a kiln, the flow of the pipeline natural gas is 50-5000m<3>/h, and the volume ratio of the added rare earth polymerizing agent is 0.1-0.3%; during a heat treatment process, the working pressure of air is at 0.055-0.12Mpa; during a baking process, the working pressure of air is at 0.1-0.2Mpa; during a working process, the novel industrial gas is ignited at first, and then the oxygen or air is added, the flame is adjusted into neutral flame and is in blue and white color, the noise is made, and the length of inner flame is 6-9mm when the metal is cut; the stability of the inner flame is excellent when the kiln is heated.

Description

1. Technical field: [0001] The invention belongs to the technical field of fluid fuel combustion methods, and relates to the application technology of a new type of pipeline industrial gas generated by adding rare earth polymerization agent to natural gas. 2. Background technology: [0002] Acetylene gas, propane gas, and natural gas are outstanding representatives of industrial gas, which play an irreplaceable role in cutting, welding, baking, heating, and spraying. The production of one ton of calcium carbide requires the consumption of several tons of coal and chemical auxiliary materials and thousands of kilowatt-hours of electricity. The production of calcium carbide into acetylene gas also consumes a large amount of water, consumes a large amount of non-renewable resources, and produces a large amount of acetylene waste residue, which seriously pollutes the environment. In addition, acetylene gas is extremely dangerous during use. Acetylene gas is prone to explosion wh...
