Description
Technical field
The present invention relates to concentration and evaporation equipment technical field, more particularly to a kind of controllable water-locator and dense using its falling liquid film
Contracting machine.
Background technology
Falling film concentration is to add feed liquid from falling film evaporator heating chamber upper tube box, through water-distributing device, is evenly distributed to each
In heat exchanger tube, under gravity and airflow function, flowed from top to bottom into uniformly membranaceous.Falling film concentration is small because of energy consumption, is frequently utilized for
The liquid concentration evaporation of medicine, food.
But existing water-locator can not control the original depth of liquid film, liquid film is too thin, is vaporized completely, and heat exchanger tube occurs
Dry wall phenomenon；The too thick then enrichment factor of liquid film is low, increases concentration cycles number of times；So that the easy fouling of falling film concentrating device or dry
Wall, heating tube is longer, and space-consuming is big.And contain some macromolecular substances (such as polysaccharide, starch, colloids extracts of Chinese herbal medicine more
Deng), band particle fouling and biofouling mixture etc., therefore Chinese herbal medicine solution easily condenses and causes fouling, and discomfort uses drop
Film is concentrated, now in the industry to being concentrated using forced circulation more than extracts of Chinese herbal medicine.Though forced circulation concentrates less scaling, energy consumption
Greatly, extracts of Chinese herbal medicine high processing costs are caused.
The content of the invention
