Technical characteristics of glass-lined enamel film evaporator.

1、Hanchei Chemical equipment glass-lined film evaporator can be operated under high vacuum: *Special design makes the evaporator can operate stably under vacuum conditions; due to the pressure loss, the evaporating surface of the film-forming inside the whole evaporation cylinder wall can maintain a high vacuum degree.

2、Zibo Hanchei glass-lined film evaporator has the pressure loss: because in the design of the equipment makes the "liquid flow" and "gas flow" become two * independent "channels ". The "liquid flow" is evenly spread on the inner wall of the evaporation cylinder (and forced to form a film) under the action of centrifugal force; the evaporated "gas flow" leaves the evaporator from the space of the evaporation cylinder* almost unobstructed, so the pressure loss (also called resistance drop).

3, glass-lined film evaporator has high heat transfer coefficient, high evaporation strength characteristics: because of the turbulent state of the liquid film greatly reduces the thermal resistance, effectively improve the total heat transfer coefficient; special structure design and short residence time to inhibit the material in the wall coking, scaling to ensure the stability of the total heat transfer coefficient of the system; material boiling point is reduced, increasing the temperature difference between the material and the heating medium (steam), improve the Heat transfer strength and evaporation strength.

4, the material in the glass-lined film evaporator overflow time is short: the material in the evaporator overheating time is very short, about 3 ~ 4 seconds (depending on the material viscosity and different), can effectively prevent heat-sensitive materials in the evaporation process decomposition, polymerization and deterioration, is conducive to improving product quality.

5、Glass lined glass evaporator has strong adaptability and convenient operation: glass lined film evaporator can handle all chemical media (except fluorine ion) except HF, concentrated phosphoric acid (concentration>30%, temperature>150℃), strong alkali (PHgt;12 and temperature gt;100℃), with strong adaptability. Easy to operate and maintain, and the maintenance workload is small.

Example of use.

Materials in the material tank through the pre-heater into the film evaporator, wastewater scraper film evaporator, film evaporator under high vacuum will be instantaneous evaporation of materials, gaseous state through the condenser into the storage tank, evaporator, residue directly into the bottom of the pot storage tank.

In addition can also be used as solvent recovery, distillation tower bottom reboiler, or a compound instant reaction and other multi-purpose.
