Intelligent visual ethylene cracking furnace teaching model

Abstract

The invention relates to an intelligent visual ethylene cracking furnace teaching model which comprises a radiation section, a convection section and a quenching boiler, wherein the radiation section and the convection section are symmetrically distributed. Vertical radiation tubes are distributed in the radiation section. A bottom burner and a side wall burner are arranged on the radiation section. The convection section is located on the upper portion of the radiation section. Horizontal convection tubes are distributed in the convection section. The teaching model is characterized in that the convection section, the radiation section, the convection tubes and the radiation tubes are made of transparent materials. A boiler body and a heat exchange pipeline of the quenching boiler are made of transparent materials. The bottom burner and the side wall burner are colored lamp simulation burners. Liquid enters the teaching model from a liquid inlet of the convection section and is discharged through the convection tubes, the radiation tubes and the heat exchange pipeline of the quenching boiler, and an ethylene cracking simulation experiment is completed. The intelligent visual ethylene cracking furnace teaching model is scientific and reasonable in structural design, and by means of the transparent materials and the simulation experiment, teaching researches are visual and intelligent.

Description

technical field [0001] The invention relates to petrochemical olefin cracking equipment, in particular to an intelligent visual ethylene cracking furnace teaching model. Background technique [0002] The ethylene cracking furnace is the core equipment of the ethylene production unit. Its main function is to process various raw materials such as naphtha into cracked gas, and provide it to other units, and finally process it into ethylene, propylene and various products. The ethylene cracking furnaces currently used in the market can be technically divided into double radiation chambers, single radiation chambers and millisecond furnaces; from the furnace type, they can be divided into CBL cracking furnaces, SRT cracking furnaces, USC cracking furnaces, KTIGK cracking furnaces, and millisecond cracking furnaces. Cracking furnace, Pyrocrack type cracking furnace, etc. During industrial production naphtha Enter the convection tube to preheat to the required temperature, then p...

AI Technical Summary

Problems solved by technology

During industrial production naphtha Enter the convection tube to preheat to the required temperature, then pass through the radiant tube for cracking, and then flow through the quench boiler to separate and collect ethylene and propylene. The whole experiment is very complicated

Industrial ethylene cracking furnaces are made of stainless steel, and the internal cracking process cannot be seen, which is not convenient for research and analysis, and the use of real fuel heating for experimental research results in energy and equipment consumption, wasting manpower and material resources
