Application of shell and tube heat exchanger
Distillation reflux system
Application of tubular heat exchanger in pharmaceutical and chemical production, the materials react in the reflux state, and the reaction is carried out after the reaction is completed The evaporated solvent needs to be condensed to a low-temperature state that is easy to store, so the heat exchanger particularly requires a long heat exchange flow channel. Under such process conditions, the conventional heat exchanger used has a large area and volume.
Based on this requirement, the wound tube heat exchanger extends the condensation stroke, greatly reducing the heat exchange area and equipment volume without increasing investment, and ensuring the solvent recovery rate to the maximum extent.
Concentration system
Tubular heat exchangers are used in pharmaceutical and chemical production to concentrate materials, especially for heat-sensitive materials or high-boiling solvents. Concentration under reduced pressure is usually used. At this time, the boiling point of the solvent is reduced. , the vapor phase has a high flow rate in the vacuum system, so the process has strict requirements on the flow channel. Under such conditions, the overall heat transfer coefficient of the heat exchanger will be greatly reduced, the difficulty of heat exchange will increase several times, and the phenomenon of material leakage during production will also be serious.
The spiral tube heat exchanger is designed in a multi-tube bundle model based on the characteristics of this system, enlarging and extending the flow channel. The material can be quickly and completely condensed in the flow channel with enhanced heat transfer, which reduces the cost of production raw materials and avoids Environmental hazards arise.
Distillation system
The application of tubular heat exchangers in the process. When the recovered solvent cannot meet the technical indicators used in production, distillation needs to be carried out to obtain high purity and high content of solvent to meet the production requirements. Production application requirements.
The heat exchanger of this system is generally installed on a tower top platform of tens of meters. The heat exchange area and equipment volume are relatively large. It requires a large enough installation platform and stable infrastructure. The equipment needs high-power hoisting in place. Equipment is a huge investment for customers.
The compact structural design of the wound tube heat exchanger and forced counter-current heat exchange greatly reduce the weight and volume of the equipment while greatly improving the heat exchange efficiency. This not only saves a lot of platform construction infrastructure and subsequent maintenance costs for customers, but also reduces the risk of equipment maintenance for workers working at high altitudes.
Tail gas waste heat recovery
The application of tubular heat exchangers in the production of many industries, there is often a large amount of tail gas and waste heat that needs to be recovered, such as the tail gas after vacuum pumps, secondary flash waste steam, etc. A large amount of recyclable materials and waste heat are important aspects of energy conservation and emission reduction that are controllable by enterprises. Under such conditions, due to the poor quality of materials, it is difficult for simple heat exchange equipment to achieve full and valuable recovery, and many companies have no choice but to absorb or directly discharge.
Under this working condition, the wound tube heat exchanger uses its reverse winding tube bundle to enhance heat transfer, so that poor quality materials can fully exchange heat, and the exhaust gas waste heat recovery brings energy saving and emission reduction benefits. It can return equipment investment in the short term and continuously produce energy-saving benefits in future production.
Extraction of Traditional Chinese Medicine
In the production of traditional Chinese medicine, the active ingredients of Chinese medicinal materials need to be concentrated and extracted. The alcohol extraction and water extraction process are generally used. Depending on the production variety and process, there are also cases of other materials. Concentration Vacuum extraction is generally used during extraction. The current situation of concentrated extraction of traditional Chinese medicines involves incomplete condensation of materials and material leakage, resulting in production waste and environmental pressure.
Wound-tube spiral shell-and-tube heat exchangers ensure extraction during the extraction of traditional Chinese medicines. Under process conditions, the materials are completely condensed to reduce production costs. And due to the small installation volume of the equipment, the traditional connection method is completely matched with the on-site equipment.
System
The application of tubular heat exchangers in pharmaceutical and food and beverage production requires online cleaning of process equipment and containers to remove residual substances on the surface and kill microorganisms. Traditional heat exchangers have low heating rates, large steam consumption, and occupy large space on site.
The application of the wound tube shell and tube heat exchanger in the system can make full use of steam heat and reduce steam consumption. It is different from the traditional circulating heating method to achieve instant heating and truly realize online cleaning, ready to use. The operation mode and fully welded structure ensure the system is safe and leak-free.
High-temperature instant sterilization system
The application of tubular heat exchangers in pharmaceutical and food and beverage production requires high-temperature instant sterilization of food and drugs. This system requires high heating and cooling rates. Complete the entire sterilization process within 1 minute to ensure product quality.
The wound tube shell and tube heat exchanger is optimized with new equipment technology to solve the disadvantages of leakage maintenance of heating rate steam consumption equipment.
Heating and cooling of process materials
The application of tubular heat exchangers in production requires the heating or cooling of complex and diverse materials. The materials are not in a single situation, and the components are relatively complex, so It is necessary to fully consider the physical properties of different material components when heating and cooling.
We make use of the advantages of winding tube-type asymmetric flow and efficient heat transfer, combine it with the heat exchange requirements of actual materials, make rigorous calculations, select appropriate products, and solve the heat exchange requirements of complex working conditions, so that the equipment is in the best condition. optimal operating condition.
