Zhuhai Chemical Production Line

Description :

　　Principles of Chemical Engineering Experimental Device - Bernoulli Experimental Device

　　Purpose of the experiment:

　　1. Familiarize oneself with the concepts and conversion relationships of various energies and pressure heads in fluid flow, and deepen the understanding of Bernoulli's equation.

　　2. Observe the variation of various energies (or pressure heads) with flow velocity.

　　Main configuration:

　　The Bernoulli experimental setup mainly consists of a water storage tank, a water pump, a high-level water tank, a rotor flowmeter, a Venturi tube, a pressure measuring tube, and a stainless steel frame.

　　Multi functional fine chemical production line

　　This device is designed with a modular concept to enhance students' understanding of the engineering and chemical engineering section, including public works, raw material pretreatment, reaction blending, distillation and other process sections. The device can meet the simultaneous operation and use of 5-20 people, and can be used for real material experimental operations. It can be used for the production of various fine daily chemicals such as purified alcohol, laundry detergent, dishwashing detergent, car wash liquid and glass water;

　　Equipped with 3D simulation software and a complete physical operation process

　　Train students to learn remote monitoring and process configuration switching for each operation section, cultivate teamwork awareness, and enhance effective communication skills.

　　Master the principles of common daily chemical product formulas (feeding sequence) and the functions of each component, and enhance the ability to control the production process indicators of daily chemical cleaning products.

　　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.
