Send into after prime runner carries out post bake and regenerate.
In prior art, low dew point rotary dehumidifier mainly uses electrical heating or steam-heated reconstituted form, regeneration
Temperature requirement is high, and energy consumption is high, causes use cost high, and components aging is fast, and maintenance operation is expensive.So, how to save energy and reduce the cost
Become a difficult problem anxious to be resolved in low dew point rotary dehumidifier industry.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of energy-efficient low dew point rotary dehumidifier, for existing skill
Deficiency in art, owing to middle table cold vaporizer 10 air intake is the mixing wind that stove room air intake and one-level desiccant wheel process air-out, its
Middle one-level runner processes the temperature humidity of air-out to be changed not quite throughout the year, is a more stable process status point；Stove room
The temperature humidity of air intake is the most also more stable, thus ensure that the air intake operating mode of the cold vaporizer of middle table is more stable,
The cold vaporizer of middle table is by middle table condensation unit refrigeration, and its refrigerating capacity the most all can be more stable；The present invention designs two kinds of technique roads
Line recycle in the condensation heat of the cold vaporizer of table, as the secondary condenser in low dew point rotary dehumidifier regenerative system,
First-stage condenser and the auxiliary thermal source adding reheater condenser, thus greatly reduce the operation power of unit, both met low dew point
Air-out, achieves again relatively low regeneration temperature double goal.
For reaching above-mentioned purpose, technical scheme is as follows: a kind of energy-efficient low dew point rotary dehumidifier, including new
Wind entrance, air-supply outlet, wind exhausting outlet, stove room air intake, new wind drainage screen, the cold vaporizer of front table, one-level desiccant wheel, return air wind
