Description

Diesel cutting torch

Technical Field

The invention relates to the technical field of cutting torches, in particular to a diesel cutting torch.

Background

The principle of the gas cutting torch is to utilize the heat cutting of flame separating material produced by the mixed combustion of fuel gas (liquid) and oxygen, also called oxygen cutting or flame cutting. During cutting, the flame preheats the material to a burning point at a cutting point, and then oxygen gas flow is sprayed to enable the metal material to be oxidized and burnt drastically, and generated oxide slag is blown off by the gas flow to form a notch.

At present, the hand-held cutting torch is widely used in a plurality of processing factories, and the existing cutting torch is basically a perfect technology after continuous improvement and innovation, but has certain defects, and the existing cutting fuels are generally acetylene, propane, gasoline and diesel oil which cannot be used. The diesel oil is a light petroleum product, and a complex hydrocarbon (with carbon number of about 10-22) mixture is diesel fuel, and is mainly prepared by blending diesel oil fractions produced in the processes of crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and the like, and can also be prepared by shale oil processing and coal liquefaction, and is divided into light diesel oil (with boiling point range of about 180-370 ℃) and heavy diesel oil (with boiling point range of about 350-410 ℃). The flash point of gasoline is-45 deg.C, belonging to low flash point liquid, and is characterized by that it is flaming and burnt, when cut by cutting machine it is easy to produce spark splash, compared with gasoline, diesel oil flash point is up to 55 deg. and can be more suitable for field operation, so that it can be used on the gas cutting torch.

In combination, diesel oil is used as fuel for cutting torch, and has the advantages of saving energy, greatly reducing fuel consumption, safety, no tempering and self safety of fuel. The invention operates under complex conditions in the field, has incomparable advantages for operation sites with higher safety requirements, and can be applied to the field of military field operations, but diesel oil cannot be applied to a handheld cutting torch at present, so the invention needs improvement.
