At present, falling film evaporator is widely used in the production liquid concentration evaporation of the industries such as medicine, food, light industry, petrochemical industry, metallurgy.At present, the heat exchanger tube material in tube-type down-flow evaporator is mainly stainless steel, titanium, graphite and enamel etc., but these materials all have certain deficiency, and the thermal conductivity of stainless steel, enamel and titanium is less than 30W/mk, and heat exchange evaporation efficiency is low; The mechanical property of graphite is poor, very easily damages in practical application.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of silicon carbide ceramics tubular type falling film evaporator, have superpower wearability and permeability resistance, and it is little to take up room, and reduces use cost.
The purpose of this utility model is achieved in that
A kind of silicon carbide ceramics tubular type falling film evaporator, comprise closed housing, be respectively equipped with upper head plate and the bottom plate of level near its upper and lower two ends in housing, the housing sidewall be positioned at above upper head plate is provided with charging aperture, be positioned in the housing sidewall below bottom plate and be then provided with discharging opening, housing sidewall between upper head plate and bottom plate is respectively equipped with the relative thermal medium inlet in position and thermal medium outlet, it is characterized in that, erect between described upper head plate and bottom plate and be equipped with some silicon carbide ceramics heat exchanger tubes, the two ends of described silicon carbide ceramics heat exchanger tube pass upper head plate and bottom plate respectively.
Wherein, described upper head plate is also provided with liquid distribution trough.
Wherein, liquid to be evaporated flows into from described silicon carbide ceramics heat exchanger tube upper end, and dirty along the inner tubal wall of silicon carbide ceramics heat exchanger tube with form of liquid film.
Wherein, described silicon carbide ceramics heat exchanger tube contains the carborundum phase of more than 95%.
Wherein, the external diameter of described silicon carbide ceramics heat exchanger tube is between 9mm-50mm.
Wherein, the inside pipe wall of described silicon carbide ceramics heat exchanger tube can be smooth or be provided with inner fin structure.
