Problems solved by technology

[0003] At present, the flow field characteristics of industrial reactors with spray guns are generally analyzed by test methods, and the test research includes water model tests, pilot tests and industrial tests , where: the water model in the water model test generally adopts a reduced scale model, which is greatly different from the actual reactor size, and it is difficult to consider the physical characteristics of the fluid in the reactor, such as viscosity and density, and the flow characteristics of the fluid need to be carried out with the help of expensive equipment. Measurement; pilot tests and industrial tests generally require a lot of manpower and material resources, and there are few detection methods, which makes it difficult to collect data, and industrial tests will affect the normal operation of the reactor, resulting in the impact of normal production activities

Abstract

The invention relates to the technical field of industrial reactors, in particular to a simulation calculation method for fluid in an industrial reactor with a spray gun. The simulation calculation method comprises the following steps: carrying out closed curved surface modeling on an industrial reactor to form a geometric model of the industrial reactor; conducting meshing on the geometric model;establishing a mathematical model of the fluid in the industrial reactor; defining boundary conditions of the mathematical model; and calculating based on the boundary conditions to obtain to-be-measured parameters of the fluid so as to obtain flow field characteristics in the industrial reactor. According to the simulation calculation method, the flow characteristics of the fluid in the industrial reactor can be obtained, so that the industrial reactor is designed in a targeted manner.

Description

technical field [0001] The disclosure relates to the technical field of industrial reactors, in particular to a fluid simulation calculation method in an industrial reactor with a spray gun. Background technique [0002] Industrial reactor is a kind of reaction equipment used to realize liquid-phase single-phase reaction process or multi-phase reaction process such as gas-liquid, liquid-solid, gas-liquid-solid, etc. It is widely used in chemical industry, oil refining, metallurgy and other fields. Among them, industrial reactors such as iron-making blast furnaces, steel-making converters, and non-ferrous metallurgical furnaces are equipped with spray guns to provide reactants to the reactors, and the chemical reactions and heat transfer conditions in industrial reactors with spray guns are relatively complicated. , therefore, the design scheme needs to be verified in the design phase, and the internal flow field characteristics need to be analyzed in the operation phase. ...
