Description

A kind of heat pump drier

Technical field

The present invention relates to a kind of heat pump drier.

Background technology

Drying device is to use equipment widely, is widely used in each fields such as biology, medicine, chemical industry, agricultural.Dry It is exactly the process that moisture in material is discharged on dry process nature, but, existing drying equipment is virtually all by directly Connecing heating makes moisture in material discharge with the form of vaporous water, owing to the enthalpy of vaporous water is significantly larger than aqueous water and temperature relatively Height, thus vaporous water has also discharged substantial amounts of energy while discharging, and inevitably causes a large amount of heat energy loss, this is the most not Meet the energy-saving and emission-reduction policy of China's present stage.

On the other hand, the mode of heating of existing drying equipment is mostly directly-heated type, i.e. by steam or electric power or conduction oil Directly heating, but heaterless thermal energy conversion efficiency is relatively low, it is left that the thermal energy conversion rate of large-sized boiler also can only achieve 90% The right side, and the heat energy transfer Energy Efficiency Ratio of heat-pump-type is higher, up to more than 3, improves utilization efficiency of heat energy greatly, it is achieved energy-conservation subtract Row.

Therefore, if a kind of dehydrator can be designed, make the moisture in material with the shape of aqueous water by the heating of heat-pump-type Formula is discharged, and just can reduce the energy in dry run as far as possible to greatest extent and damage on the premise of reducing other energy loss Consumption, realizes energy-saving and emission-reduction to greatest extent.

Summary of the invention

The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, it is provided that a kind of heating by heat-pump-type Make moisture in material discharge with the form of aqueous water, the heat-pump-type of energy loss in dry run can be reduced to greatest extent be dried Device.

For overcoming the deficiencies in the prior art, the present invention takes techniques below scheme:

A kind of heat pump drier, goes along with sb. to guard him including insulation, it is characterised in that;Interior composition dry environment, Qi Zhongyou are gone along with sb. to guard him in insulation Water tank, injects water logging and does not has spiral coil A therein and spiral coil B in water tank;Compressor A, spiral coil A, capillary tube A, dish Pipe A and associated conduit constitute A group heat pump cycle dehumidification system;Compressor B, coil pipe B, capillary tube B, spiral coil B, outer coil pipe and Associated conduit constitutes B group heat pump cycle heating system;A system realizes insulation and goes along with sb. to guard him the condensate drainage of interior cooling and vaporous water, and By the heat storage of cooling and vaporous water condensation release in water tank;B system realizes insulation and goes along with sb. to guard him moisture in interior intensification and material Gasify in going along with sb. to guard him to insulation, and absorb the heat that A system is stored in water tank;AB system alternation realizes insulation and goes along with sb. to guard him interior thing Expect the evaporation of moisture, condense and discharge, and in water tank, the storage of heat utilizes.

Described water tank is external attemperater or built-in non-attemperater.

During equipment work, first by B group heat pump cycle heating system, interior material is gone along with sb. to guard him in insulation and heat, now thing In moisture in material can gasify due to heating to insulation and goes along with sb. to guard him, in material, needed for moisture vaporization, energy major part derives from water tank The heat of middle storage, is realized with the water heat exchange in water tank by spiral coil B;Then A group heat pump cycle dehumidification system is restarted, Now insulation is gone along with sb. to guard him interior saturated vaporous water and can be condensate in due to cooling in refrigeration air-conditioner on machine, drain pipe discharge, it is achieved Being dried of interior material is gone along with sb. to guard him in insulation, and the heat of vaporous water condensation release is stored up with the water heat exchange in water tank again by spiral coil A Exist in water tank.AB system alternation realizes insulation and goes along with sb. to guard him the evaporation of interior material moisture, condenses and discharge, and heat in water tank The storage of amount utilizes, and owing to being heat pump work, its Energy Efficiency Ratio is up to more than 3.

Compared with prior art, the beneficial effects of the present invention is:

1, in material, the discharge of moisture is entirely the form discharge with condensed water, does not has other dehumidifying, heat extraction mouth, due to vaporous water Enthalpy be significantly larger than condensed water and temperature is higher.Therefore, compared with existing gaseous state dehumidifying drying mode, energy loss is greatly Reduce, it is possible to achieve refrigerated dehumidification heat zero-emission.

2, inject water logging in water tank and do not have spiral coil A therein and spiral coil B, be evaporated to insulation at material moisture and go along with sb. to guard him The heat stored in water tank can be discharged time interior, can with the heat of absorption condensation release also when the condensation of interior vaporous water is gone along with sb. to guard him in insulation It is stored in water tank, it is achieved the storage of moisture evaporation and condenser heat uses, and reduces energy consumption for drying to greatest extent.

3, water tank and external environment atmospheric heat can be carried out cascade evaporation absorption when intensification is gone along with sb. to guard him in insulation, then input insulation Going along with sb. to guard him interior release, promoting to heat up is dried, and be particularly suitable for Cold Winter heats dry cycle.

Water tank, in addition to Collaborative Control accumulation of heat, controlling thermal output buffering, heat accumulation function, is gone along with sb. to guard him interior temperature when insulation simultaneously and is higher than During water tank temperature, tank outer wall can absorb heat and make moisture in gas phase separate out discharge, environmental dehumidification in promoting;It is less than when going along with sb. to guard him interior temperature During water tank temperature, tank outer wall meeting heat release makes to go along with sb. to guard him interior environment and is easier to heat up, and promotees to go along with sb. to guard him interior environment and can be brought rapidly up promoting thing Material is dried.
