Device description

In order to improve the effect of vapor-liquid separation, and both in addition to foam, prevent entrainment, using a three-stage separation, capture mode: one is the vapor-liquid tangent into the evaporation tank using centrifugal force and tank settlement; Two is the top of the evaporator with efficient air filter filter layer; The third is the addition of impact type trap, so as to prevent the loss of material liquid entrainment by secondary steam, even for the material liquid easy to produce foam (such as soap-containing Chinese medicine liquid) can also achieve satisfactory separation effect.

working principle

WZ type external circulation vacuum evaporation device is mainly composed of tubular heater, evaporation tank, circulation pipe and other auxiliary equipment.

After the material liquid is heated to the boiling point in the heater tube, part of the water vaporizes, so that the heat energy is converted into kinetic energy of upward movement; At the same time due to the heating pipe vapor liquid mixture and circulating pipe not boiling between the material produced between the heavy difference, in the expansion kinetic energy and the heavy difference induced by the natural circulation of the material liquid (the material liquid in the heating pipe circulation speed is less than 1m/s), the more heat the material liquid, the better the boiling, the circulation speed will be larger. Due to evaporation under the action of vacuum, the evaporation temperature of the material liquid can be controlled below 50℃ to some extent. The secondary steam from the evaporation is captured by the screen defromer and liquid trap, and is condensed by the water jet pump. After centrifugal rotation, the material liquid in the evaporation tank returns to the lower part of the heater along the outer circulation pipe for recircular heating and evaporation, so the circulation heating and evaporation (about 15-20 minutes), when the required concentration is reached, the continuous discharge begins, and the continuous feeding at the same time, thus forming a continuous vacuum concentration operation.
