Precautions for the use of chemical refrigeration and heating circulation systems
In chemical production, the reaction will generate heat, which will cause the heat to be uneven. If it is not discharged in time, it will increase the temperature in the kettle and cause danger. The existing heating system of the reactor is relatively simple, and the process of reducing the temperature in the reactor to room temperature takes a particularly long time, and the heat energy cannot be used rationally, resulting in a waste of some resources. However, if the waste heat is released too much, the overall temperature will drop unstable, and the product quality will be affected. Therefore, it is very important to have a cooling and heating cycle system.
The characteristic of the reactor is that the volume and heat capacity are very large, and endothermic and exothermic reactions can occur at any time, so the entire process time will be lengthened when collecting. When the polymerization reaction occurs in the reactor, the chemical raw materials are changing, which will cause changes in the process and materials, and a series of endothermic and exothermic reactions occur. Therefore, the chemical production itself is very complicated.
Points for attention in the use of chemical refrigeration and heating cycle systems (1) When the reactor is in operation, it needs to strictly follow the relevant standards to prevent over-temperature and over-pressure. (2) Strict temperature control in accordance with requirements. (3) It is necessary to prevent the superposition of temperature difference stress and internal pressure stress to ensure that the equipment does not appear to be strained. (4) The ratio of ingredients must be strictly controlled to prevent violent reactions.
With the rapid development of society, in order to adapt to the current development needs of the chemical industry, it is necessary to strengthen temperature control in the chemical production process and optimize the design of the temperature control system to ensure that it meets the requirements for use and ensures the normal operation of the equipment.
February 6, 2021If you need equipment to distill CBD, you need to scrutinize your choices, as the equipment can vary in its features and design. When you use equipment that produces a CBD distillate, you want to seek out a system made by a manufacturer that provides proven and reliable products. You should also work with a business that can train you on the use of the equipment you buy.view
