The main features of the vertical condenser are: Due to the high cooling flow and flow rate, the heat transfer coefficient is high, generally about K = 600 ~ 700 (kcal / m2? H? ℃). Vertical installation covers small areas, and can be installed outdoors. Cooling water flow directly and have high flow rate, so not need high water quality, the general water can be used as cooling water. Scales in pipe can be easy removed, and do not have to stop the refrigeration system work.But in the vertical condenser, the rise temperature of cooling water is generally only 2 ~ 4 ℃, logarithmic average temperature difference is generally about 5 ~ 6 ℃, so need much water. And because the equipment is placed in the air, the tube is susceptible to corrosion and is easier to find its leaking.
The natural external heating evaporator is an efficient evaporation system, whose main function is to condense the solutes in the liquid through evaporation, thereby achieving the separation and recovery of the liquid. The system adopts a circulating external heating method, which transfers heat to the evaporator through the heater, causing the liquid to evaporate and form steam inside the evaporator. The steam then condenses into liquid through the condenser, achieving liquid separation and...
External heating evaporator is also called Long-tube vertical evaporator. It is composed of heating chamber, evaporation separation chamber and circulating pipe, etc.The feed liquid enters the heating inner tube from the bottom of the heating chamber. The heating steam flows between the tubes, and the feed liquid boils in the tubes and quickly vaporizes. The flow rate of the secondary steam in the pipe is very high, 20-30m/s at normal pressure and 80-200m/s at decompression. It spirals up and...

According to different materials, there are generally: polyethylene storage tanks, polypropylene storage tanks, glass fiber reinforced plastic storage tanks, ceramic storage tanks, rubber storage tanks, stainless steel storage tanks, etc. As far as the cost performance of storage tanks is concerned,...
The steam condenser can be condensed in the surface steam condenser in two ways. First, the cooling water passes through a series of pipes, and the steam passes through the pipes. Secondly, steam flows through a series of pipes, and water flows outside the pipes in the form of film. The surface condenser is mainly composed of cast iron shell. The shell is cylindrical and the two ends are closed to form a water tank. The tubesheet is located between each top cover and housing. Many water pipes...
Industrial distillation tower also belongs to petrochemical equipment. The tower is a process equipment with a cylindrical welded structure, composed of a cylinder, a head, and a support. It is a non-standard equipment specially designed and manufactured for certain production process requirements. Tower is a vertical equipment used for distillation, purification, absorption, distillation, and other chemical unit operations. It is widely used for gas and liquid phase or liquid and liquid phase...
The working principle of the condenser is that the gas passes through a long tube (usually coiled into a solenoid) to let the heat escape to the surrounding air. Metals such as copper have strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks with excellent heat conduction performance are often attached to the pipes to increase the heat dissipation area to accelerate heat dissipation, and air convection is accelerated...
