Abstract
The utility model relates to an energy-conserving rotary dehumidifier is used in air feed dehumidification. The air-air heat exchanger (3) arranged in the regenerative air inlet and exhaust channels is used for recovering sensible heat and latent heat discharged along with the regenerative air and preheating the inlet airflow of the regenerative air, thereby reducing the power and energy consumption of the regenerative air heater (4) and achieving the purpose of energy conservation.
Description
The utility model relates to a kind of energy-conservation rotary dehumidifier that is used for air dewetting.
Rotary dehumidifier is to utilize the cellular porous road Dehumidifying rotary wheel of surface applied hygroscopic agent and slowly rotation to adsorb the dehumidification equipment that runs through moisture in the humid air that flows through this runner.Runner after the moisture absorption must blow through the baking of high temperature drying air-flow, can make hygroscopic agent dehydration regeneration.So regenerated air heater in the existing rotary dehumidifier, all need consume big energy (electric energy or steam) and be used for the thermal regeneration air, just can make the hydrone vaporization of Dehumidifying rotary wheel absorption, and this part heat is discharged in the middle of the atmosphere with the regeneration air after the moisture absorption all.Regeneration energy consumption height is the existing ubiquitous shortcoming of rotary dehumidifier, in the similar products at home and abroad, does not see effective conservation measures or relevant report as yet at present.
The purpose of this utility model provides a kind of energy-conservation rotary dehumidifier, and it has heat reclaim unit, can reduce the energy consumption of regenerated air heater effectively.
The purpose of this utility model is achieved in that the regeneration air at energy-conservation rotary dehumidifier advances, in the exhausting duct, board-like or plate-fin air---the air heat exchanger of being made by the corrosion resistant metal thin plate is housed, when the inlet and outlet flow point of regeneration air does not flow through two groups of passages that are staggered and isolate mutually of this heat exchanger, exchange heat will take place: hot and humid air draft is cooled off by the low temperature air intake, discharges the sensible heat amount earlier; When temperature is reduced to dew-point temperature, can separate out condensed water again, discharge the latent heat of vaporization simultaneously.These heats (sensible heat amount and latent heat amount) all can be by air---and air heat exchanger reclaims and is used for giving the air intake air-flow of hot regeneration air, improves EAT, thereby reduces the power and the energy consumption of regenerated air heater, reaches energy-conservation purpose.
Compare with existing rotary dehumidifier, energy-conservation is outstanding feature of the present utility model.Because the regenerated air heater energy consumption accounts for about 95% of existing rotary dehumidifier total energy consumption, so reduce the energy input that the regenerated air heater energy consumption will reduce complete machine significantly, improve the moisture removal of specific energy consumption, obtain obvious energy-saving effect.
Fig. 1 is back to cutaway view according to the energy-conservation rotary dehumidifier embodiment that the utility model proposes.
Fig. 2 is the front view of this embodiment.
Fig. 3 is the dextrad view of this embodiment.
Fig. 4 is a kind of plate-fin air---the structural representation of air heat exchanger that is used for energy-conservation rotary dehumidifier.
The utility model comprises: regeneration air import (1), regeneration air filter (2), the air of band volume damper---air heat exchanger (3), regenerated air heater (4), Dehumidifying rotary wheel (5) and drive unit (6) thereof, regeneration blower fan (7), regeneration air export (8), water pond (9), pending humid air import (10), dry air export (11), casing (12), dividing plate (13) and control device (14) with fixed attention.Dividing plate (13) is separated into the dehumidifying and two intervals of regenerating with casing (12).Dividing plate (13) and Dehumidifying rotary wheel (5) inlet side end joints stud with sealing strip (not drawing among the figure), are used to prevent that the dehumidifying and the two strands of air-flows of regenerating from scurrying mutually.Dehumidifying rotary wheel (5) then drives slowly rotation by drive unit (6); Drive unit (6) comprises motor, decelerator (or speed changer) and driving-belt.
Pending humid air is adorned blower fan outside and is blowed down, enters the dehumidifying district by air inlet (10), and after Dehumidifying rotary wheel (5) dehumidifying, dry air is sent into the workspace by air outlet (11) through pipeline.Under the vacuum suction that regeneration blower fan (7) causes, regeneration air passes volume damper by air inlet (1) and regeneration air filter (2) enters air---air heat exchanger (3), given after heat heats up by the high temperature air draft, again through further heating of regenerated air heater (4), become the high temperature drying air-flow, see through Dehumidifying rotary wheel (5), finish the dehydration regeneration of hygroscopic agent, become hot and humid air-flow, enter air---other one group of passage of air heat exchanger (3), cooled off by the low temperature air intake simultaneously, after discharging sensible heat amount and latent heat amount and separating out condensed water, enter atmosphere by exhaust outlet (8); Condensed water then collect, discharging by coagulating by water pond (9).
