Distillation tower

Distillation tower manufacturer: The principle of rectification is to partially vaporize and partially condense the liquid mixture many times, and use the characteristics of different volatility of each component to achieve a unit operation for the purpose of separation. The vapor inlet of the rectification tower is usually placed at the bottom of the tower. The vapor phase evaporated from the tower is in countercurrent contact with the descending liquid. During the two-phase contact, the volatile (low boiling point) components in the descending liquid continuously transfer to the gas phase. The hard-to-volatile (high boiling point) components in the liquid are continuously transferred to the descending liquid. The closer the gas phase is to the top of the tower, the higher the concentration of its volatile components, and the closer the descending liquid is to the bottom of the tower, the more concentrated its hard-to-volatile components. , So as to achieve the purpose of component separation.

Selection of pressure vessel flange

At present, my country has established relevant standards for pipe flanges and equipment flanges. The pipe flange standards are HG20592 and HG20615, and the equipment flange standard is JB/T4700-4707. The standard requires designers to follow the standard specifications for design. In practical applications, we found that if the flange selection is blindly selected according to the design standards, the cost is often higher, and the final effect is often not satisfactory.

Common problems in formula calculation of spiral plate heat exchanger

The spiral plate heat exchanger gives the constant in the selection formula in the numerical mode, and adjusts the result of the dirt thermal resistance on the outer surface of the tube, but this formula will cause two problems: the formula for the heat transfer coefficient of the flue gas involved, the kinematic viscosity, and the general The numerical calculation of the rand number is more complicated, and it is not suitable to do some functions and the simulation model calculated by the regression formula;

Detailed introduction of 5 types of new high-efficiency heat exchangers, increase knowledge!

The heat exchanger manufacturers will give you a detailed introduction to the five types of heat exchangers: In recent years, the domestic has improved the performance of heat exchangers in terms of energy saving and efficiency. It has improved heat transfer efficiency, reduced heat transfer area, reduced pressure drop, and increased device heat. Significant achievements have been made in the research of strength and other aspects, and with the large-scale and high-efficiency industrial installations, heat exchangers have also tended to be large-scale, and they are developing in the direction of low temperature difference design and low pressure loss design. 1. Pneumatic spraying finned tube heat exchanger Russia has proposed an advanced method, namely pneumatic spraying, to improve the performance of the finned surface.

How to clean the heat exchanger

For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc. have encountered many problems when cleaning the heat exchanger: the scale and other deposits cannot be completely removed, and the acid solution causes corrosion to the equipment. A loophole is formed, and the residual acid will cause secondary corrosion or under-scaling corrosion to the material, which will eventually lead to the replacement of equipment. In addition, the cleaning waste liquid is toxic and requires a lot of money for wastewater treatment.

What are the classifications of heat exchangers

The classification is as follows: According to the principle of heat transfer 1. Dividing wall heat exchangers Dividing wall heat exchangers are two kinds of fluids with different temperatures flowing in the space separated by the wall, through the heat conduction of the wall and the convection of the fluid on the wall surface, the two fluids Exchange heat between. Partition wall heat exchangers include shell-and-tube heat exchangers, double-pipe heat exchangers and other types of heat exchangers.

What is a reactor?

The broad understanding of the reactor is a stainless steel vessel with physical or chemical reactions, and the structural design and parameters of the vessel are carried out according to the requirements of different process conditions. The heat exchanger manufacturer claims that the configuration, design conditions, process, inspection and manufacturing, and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. The pressure vessel must follow the standard of GB150 {steel pressure vessel}, and the atmospheric pressure vessel must follow the standard of NB/T47003.1-2009 {steel welded atmospheric pressure vessel}.
