Description
Technical field
Dry Heat Pump Design technical field is the utility model is related to, more particularly to a kind of more drying machines join with source pump
Close the drying unit set.
Background technology
Heat pump is applied to the middle low temperature drying of such as damp grain containing wet stock, the spy with distinct energy-conserving and environment-protective
Point, the highest attention of heat power engineering field and various circles of society is caused.Considerable heat pump air conditioner enterprise, try water grain fever
Pump is dried, timber heat pump drying, tobacco leaf, jujube, matrimony vine, grape, black fungus, Chinese herbal medicine etc. agricultural product heat pump drying, ground rice,
Noodles, marine product, pickled and cured meat etc. food article heat pump drying, achieve notable performance.
But heat pump is used for grain dry, also there is following key technical problem:
First, producing high temperature air will be greatly reduced heat pump heating energy efficiency ratio
Heat pump heating energy efficiency ratio, circulation temperature rise (condensation temperature-evaporating temperature) with heat pump is into negative correlativing relation;Follow
Circumstance temperature liter is lower, and heating energy efficiency ratio is higher;Circulation temperature rise is higher, and heating energy efficiency ratio is lower, and circulates temperature rise and often expand 10 DEG C,
Heating energy efficiency ratio reduces by 20% or so;When circulation temperature rise reaches more than 60 DEG C, the economy of source pump will be very poor.
2nd, drying device air-out dust emission pollution atmospheric environment
In drying process, density reduces, and containing wet containing the smaller particulate matter of a large amount of particle diameters in wet stock after dewatering
The tight type of material main body is coupled and is difficult to maintain, and under the sweeping along of dry gas stream, departs from main body and flies upward, turn into dust;
By taking grain-drying as an example, damp grain is self-contained and paddy hair that is sweeping along, paddy clothing and soil dust, is filled drying
Put after sloughing moisture by dry-heat air, become slim and graceful, lax, depart from cereal main body wantonly, with the air-out of drying device
Atmospheric environment is discharged into, turns into the important sources of atmosphere pollution;
3rd, drying is implemented as medium using high temperature air and accelerates the oxidation containing wet stock
Containing the inorganic constituents and organic principle in wet stock, metal class, salt, hydrocarbon class, macromolecule are largely belonged to
Class, it is most of to be combined with oxygen, it is oxidized;In the high-temperature atmosphere containing oxygen, the speed of oxidation is faster.
Some thermal sensitivity biological species contain wet stock, and under high temperature and aerobic conditions, there is also bioactivity reduces even
Inactivation;
Such as grain is dried under high temperature aerobic conditions, and not only broken rice rate improves, and because high-temperature oxydation also results in rice
The color sensation in face is poor, poor taste, nutritional properties are deteriorated;Tobacco leaf is dried under high temperature aerobic conditions, and not only the gloss of tobacco leaf, texture become
Difference, and a large amount of voloxidation of fragrance component in tobacco leaf are scattered and disappeared, and the quality grade of tobacco leaf declines.
