　　Production of Composite Coatings on Chemical Integrated Production Line

　　Lacquer is a commonly used coating series in wall art construction. It is a textured thick paste craft variety. Other names for brushed paint include textured paint, artistic paint, bone paste, and elastic bone paste. It is a large branch of paint in the thick paste system and is generally referred to as "multi-layer paint" in industry terminology.

　　The main purpose and configuration of the experimental apparatus for chemical engineering principles

　　Principles of Chemical Engineering is a highly practical technical foundation course and a core course in various chemical engineering majors. It belongs to the scope of engineering disciplines and applies the basic principles of natural sciences to analyze and process the physical processes in chemical production. The experiment of chemical engineering principles, like theoretical courses, is an important part of the entire teaching of chemical engineering principles. The two complement each other and play a crucial role in cultivating talents in chemical engineering and related fields. The main task of the chemical engineering principle experimental device is to undertake theoretical teaching, experimental teaching, and course design guidance for courses such as "Chemical Engineering Principles", "Chemical Engineering Fundamentals", "Fluid Flow and Heat Transfer", "Mass Transfer and Separation Processes" in relevant majors throughout the school.

　　Heat exchanger is not only a universal process equipment widely used in various industrial sectors such as petroleum, chemical production lines, fertilizers, power, metallurgy, transportation, etc., but also an effective device for waste heat recovery and utilization. Shell and tube heat exchanger is currently a commonly used structural form of heat exchange equipment in thermal systems. The support structure of the tube bundle is the key structure of the shell side, which can generate the desired flow pattern of the shell side fluid and is an important factor in determining the heat transfer and flow resistance performance of the heat exchanger. Different shell side fluid flow patterns result in significant differences in the heat transfer and flow resistance performance of the heat exchanger.

　　The comprehensive chemical production line is divided into three types of shell and tube heat exchangers according to the flow state of the shell side fluid: transverse flow, longitudinal flow, and spiral flow. Traditional baffle heat exchangers have lateral fluid flow in the shell side, which results in strong erosion of the heat transfer tubes. However, it is prone to flow and heat transfer dead zones, and the heat transfer area cannot be fully utilized. The flow resistance is high, and scaling is easy to occur. Moreover, when the flow velocity of the shell side fluid is high, induced vibration damage is prone to occur, which limits its application; The baffle rod heat exchanger achieves longitudinal flow of shell side fluid, exhibiting better heat transfer, low flow resistance, anti vibration and anti scaling performance. However, it also has the defects of insufficient compactness and poor heat transfer effect under low heat conditions; The spiral baffle heat exchanger realizes the spiral flow of shell side fluid, with a relatively smooth change in fluid velocity, and can effectively eliminate dead zones and backmixing phenomena.
