Supply of second-hand 50 square stainless steel chemical condenser

Supply of second-hand 50 square stainless steel chemical condenserThe heat transfer area must be sufficient, otherwise it will be difficult for all the secondary steam entering the condenser to be cooled, resulting in an increase in evaporation temperature and a decrease in production
Tube condenser
Production capacity. In addition to selecting an appropriate heat transfer coefficient for the condenser, some factors that directly affect the heat transfer efficiency cannot be ignored when calculating the heat transfer area of the condenser.
(1) The influence of the heat released by condensed water on the condenser performance
The condensed water in each shell side of the multi effect evaporation equipment is generally discharged together with the condensed water in the shell side of the condenser from the condenser (this is not only simple in equipment structure, but also mainly energy-saving). Due to the fact that the temperature of the condensed water in the shell side of the condenser is higher than that in the shell side, and the vacuum degree is high, when the condensed water enters the shell side of the condenser, it releases a certain amount of heat due to self evaporation. Therefore, when calculating the heat transfer area of the condenser, this part of the heat should be included in the calculation.
(2) The impact of steam extracted from various non condensable gas interfaces on the condenser

Supply of second-hand 50 square stainless steel chemical condenserMulti effect evaporation equipment generally has two non condensable gas interfaces on each shell side to extract non condensable gases from the shell side. The upper and lower condensate interfaces are directly connected to the inlet of the condenser. Each shell side of the effect body carries steam, while the tube side carries materials. Often, non condensable gas is extracted from the non condensable gas interface while a certain amount of heating steam is also brought out. This is because theoretically, in the heating process, there is no remaining heating steam for each shell side based on heat balance. In fact, each effect can be seen as a condenser heating steam, and it is impossible to have no surplus because heat loss also needs to be considered in the calculation process.
