The utility model discloses a rising/falling liquid film evaporation and wiped film evaporation's joint evaporation mode makes the material take place gas-liquid separation earlier, and cooperation tangent line feeding and defoaming are handled for most low boiling point light component direct segregation discharge, carry out the wiped film evaporation after the separation again, effectively improved holistic evaporation capacity of evaporimeter and evaporation efficiency from this, it is effectual to have remain wiped film evaporator evaporation simultaneously, the advantage that the light component evaporation rate is high.
Description
Technical Field
The utility model relates to an evaporimeter technical field, concretely relates to gas-liquid separation formula joint evaporator.
Background
The wiped film evaporator is a novel high-efficiency evaporator which is forced to form a film by a rotary wiped film device, flows at a high speed, has high heat transfer efficiency and short residence time (about 10-50 seconds) and can perform falling film evaporation under a vacuum condition. When the device works, the mixed material radially enters the evaporator from the upper part of the heating area, is distributed on the heating wall surface of the evaporator through the distributing device, and is continuously and uniformly scraped into a liquid film with uniform thickness by the rotary film scraper on the heating surface and is spirally pushed downwards. In the process, the rotating film scraper ensures that a continuous and uniform liquid film generates high-speed turbulence and prevents the liquid film from coking and scaling on a heating surface, thereby improving the total transmission coefficient. The light components are evaporated to form steam flow which rises and reaches an external condenser directly connected with the evaporator through a steam-liquid separator; the heavy component is discharged from a cone material port at the bottom of the evaporator.
However, when the material is introduced into the wiped film evaporator, the heavy component and the light component are both in liquid state, and although the wiped film evaporator has good evaporation effect and high evaporation rate of the light component, the distribution and heating evaporation capacity of the wiped film evaporator is small, so that the overall evaporation separation efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an evaporator is united to gas-liquid separation formula, it has solved the problem that single use wiped film evaporator evaporation capacity is little, evaporation and separation efficiency is low.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
a gas-liquid separation type combined evaporator comprises a wiped film evaporator, wherein the wiped film evaporator is provided with a feed inlet and an exhaust outlet, the feed inlet extends into the wiped film evaporator and is tangent to the inner wall surface of the wiped film evaporator, and the exhaust outlet is provided with a defoaming mechanism;
the device also comprises a rising/falling film evaporator, and the rising/falling film evaporator is connected with the feed inlet of the wiped film evaporator through a pipeline.
The further improvement is that the defoaming mechanism adopts a defoaming net, a baffle plate or a cyclone separation structure.
The further improvement lies in that a stirring paddle is arranged in the wiped film evaporator and is synchronously driven with a scraper of the wiped film evaporator.
The beneficial effects of the utility model reside in that: the combined evaporation mode of rising/falling film evaporation and wiped film evaporation is adopted, so that the material is subjected to gas-liquid separation firstly, tangential feeding and defoaming treatment are matched, most of light components with low boiling points are directly separated and discharged, and wiped film evaporation is carried out after separation, so that the overall evaporation capacity and evaporation efficiency of the evaporator are effectively improved, and the advantages of good evaporation effect and high evaporation rate of the light components of the wiped film evaporator are retained.
