Embodiment approach 1

[0128] Embodiment 1: a kind of production process of acetylene-free industrial cutting gas, its step comprises:

[0129] (1) Pre-treatment of compressed air: After the compressed air is filtered, dried, and depressurized, it enters the storage tank through the compressed air inlet, and liquid fuel is stored in the storage tank;

[0130] (2) Preliminary gasification of liquid fuel: the compressed air entering the storage tank generates a large number of bubbles through the bubbling gasification device, which promotes the preliminary gasification of the liquid fuel, and at the same time heats the liquid fuel to generate preliminary gas;

[0131] (3) Secondary gasification of liquid fuel: the preliminary gas enters the gas collection tank through the gas outlet connecting pipe, and is heated for secondary gasification to obtain industrial cutting gas;

[0132] The liquid fuel includes light hydrocarbon fuel, combustion improver, dispersant, solubilizer, catalyst and solvent.

Embodiment approach 2

[0133] Embodiment 2: The production process of acetylene-free industrial cutting gas as described in Embodiment 1, the storage tank is provided with a heating system.

Abstract

The invention provides a production technique of acetylene-free industrial cutting gas. The technique comprises the following steps: (1) pretreatment of compressed air: compressed air is dried, and enters a storage tank via a compressed air inlet, wherein a liquid fuel is stored in the storage tank; (2) primary gasification of liquid fuel: the compressed air entering the storage tank is treated by a gasifier to generate abundant bubbles so as to promote the primary gasification of the liquid fuel, and meanwhile, the liquid fuel is heated to generate primary combustible gas; and (3) secondary gasification of liquid fuel: the primary combustible gas enters a gas collection tank via a gas outlet connecting pipe, and is heated to implement secondary gasification, thereby preparing the industrial cutting gas. The liquid fuel comprises a light hydrocarbon fuel, a combustion improver, a dispersing agent, a solubilizer, a catalyst and a solvent.

Description

technical field [0001] The invention relates to the technical field of industrial cutting gas, in particular to a production process and production equipment of acetylene-free industrial cutting gas. [0002] technical background [0003] Industrial cutting gas generally refers to the gas resources that use the flame combustion characteristics of the gas to chemically react with the structural characteristics of metals or non-metals in the process of industrial production, so that the workpiece to be operated is divided or fused, so as to achieve the effect of industrial application. [0004] Currently common industrial cutting gases mainly include: dissolved acetylene, propane, liquefied petroleum gas and mixed gas, among which dissolved acetylene is the most used, accounting for about 50%. [0005] Dissolved acetylene has many disadvantages as an industrial cutting gas, such as: black smoke and dust when ignited, polluting the working environment, and harmful to human healt...
