Separation device for reaction product of chemical fine organic synthesis

Abstract

The invention discloses a separation device for a reaction product of chemical fine organic synthesis. The separation device comprises a shell and a condenser, wherein an air inlet pipe is communicated to the side part, relative to a material liquid inlet, of the shell, and a hot-air blower is communicated to the side part of the air inlet pipe; a draining pipe penetrates through a base and is communicated to the outside; an exhausting pipe is communicated to the upper part of the shell; trays are mounted on the inner wall of the shell in staggered and equal interval manners, downcomers are mounted on the side parts of each group of the trays, through holes are formed in the middles of each group of the trays, and heat exchange pipes are mounted in each group of the trays; a hot water pumpis communicated to a water inlet end of a mother tube; an air inlet end of the condenser is communicated with the exhausting pipe; a cold water pump is mounted at the upper part of the condenser, anda spray nozzle is mounted at a water outlet end of the cold water pump; and a liquid collection tank is mounted at the lower part of the condenser, and a liquid discharging pipe is mounted at the side part of the condenser. According to the separation device, hot air is blown into the separation device through the hot air machine, and hot water is pumped into the separation device through a hot water pump, so that the heat exchange is effectively realized; and impurity gas is collected through the cooling of the condenser.

Description
