Falling film evaporator with demister

Abstract

The utility model relates to falling film evaporator technical field discloses a falling film evaporator with demister, including falling film evaporator, the top fixed connection of falling film evaporator has the connecting pipe. The utility model has the following advantages and effect: liquid enters the demister case, and the demister filter screen in the demister case will separate liquid and liquid froth, and liquid froth is intercepted to the top of demister filter screen, and the transmission of driving gear, driven gear and threaded rod is passed through when synchronous motor works, and the drive screw block drives driving air cylinder and scraper to carry out reciprocating movement transversely through connecting rod, and driving air cylinder moves while driving the scraper to move downwards until the scraper and the upper surface of demister filter screen contact, that is, realizes the reciprocating transverse movement of the scraper above demister filter screen, can effectively scrape the liquid on the top of demister filter screen and carry out froth treatment, accelerates the separation of liquid froth and liquid, thereby reaches the device convenient for the effect of removing liquid froth.
