Description
Technical field
The present invention relates to technical field, more particularly, to a kind of energy efficiency type low temperature single-wheel dehumidifying unit.
Background technology
Sorption dehumidifiers are acknowledged as mentioning the freezing of CFC ' s compressions and removed with its significant energy-conservation and environment-friendly advantage
One of wet one preferred technique, rotary wheel dehumidifying function is rapid, simple and effective reduction air humidity, using industrial exhaust heat, useless
The low grade heat energies such as heat, solar energy, natural gas are the renewable sources of energy, non-environmental-pollution, and energy consumption is low.It is widely used in food, doctor
Medicine, electronics, electrical equipment, chemical industry etc. have the industry of humidity requirement.As shown in fig. 1, at present, in common low temperature single-wheel dehumidifying unit
Have the disadvantage that：1. standard universal type, air-conditioning box uses before and after cooperation, and energy consumption is slightly higher.2. because of wheel surface temperature after regeneration
Too high, this part runner adsorption capacity is very low after going out renewing zone, and dehumidification rate is general.
The content of the invention
In view of the shortcomings of the prior art, technical problem to be solved is to provide a kind of energy efficiency type low temperature list to the present invention
Wheel dehumidifying unit, quickly recovers runner moisture pick-up properties by low temperature cold blowing, while rotary wheel dehumidifying synergy, reduces processing air-supply
Temperature, reduce regeneration energy consumption.
The present invention is to be addressed above-mentioned technical problem by the following technical programs.
Energy efficiency type low temperature single-wheel dehumidifying unit, including runner heat exchanger, regenerative heater, processing blower fan and regeneration wind
Machine, runner heat exchanger, which is distinguished, sets processing moisture absorption area, regeneration desorption area and re-generatively cooled area, and fresh air is before by runner heat exchanger
Two-way is separated into, fresh air is blown behind processing moisture absorption area by handling blower fan all the way, and another way fresh air passes through re-generatively cooled area
Successively by regenerative heater and regeneration desorption area and by regenerating blower fan discharge after being mixed with regeneration fresh air.
Preferably, processing moisture absorption area, regeneration desorption area and re-generatively cooled area be respectively 30 to 90 degree sector regions, 30 to
90 degree of sector regions and 240 degree to 300 degree sector regions.
Preferably, the upstream of runner heat exchanger is provided with surface cooler, fresh air is separated into two-way after surface cooler.
Beneficial effects of the present invention：
1. in terms of the synergy that dehumidifies, runner moisture pick-up properties is quickly recovered by low temperature cold blowing, while improve regeneration air intake
Initial temperature, reduce the power consumption power of regeneration.
2. in terms of effect is saved, relative to common single-wheel dehumidifying unit regenerate 20 DEG C on energy-conservation, wind after processing
Temperature reduces 10 DEG C, reduces follow-up air conditioner refrigerating energy consumption, dual-effect energy-saving.
Brief description of the drawings
It is intended to be easy to describe preferred embodiment in conjunction with the following drawings, does not form limiting the scope of the invention.
Fig. 1 is the structural representation of the low temperature single-wheel dehumidifying unit of prior art；
Fig. 2 is the structural representation of the embodiment of the present invention.
In figure：1- runner heat exchangers, 2- regenerative heaters, 3- processing blower fans, 4- regeneration blower fans.
Embodiment
In order to facilitate the present invention is understood, below in conjunction with the accompanying drawings in the preferred embodiment of the invention that provides the present invention is entered
The detailed description of row.
As shown in Fig. 2 the energy efficiency type low temperature single-wheel dehumidifying unit of the embodiment of the present invention, including runner heat exchanger 1, again
Raw heater 2, processing blower fan 3 and regeneration blower fan 4, runner heat exchanger 1, which is distinguished, sets processing moisture absorption area, regeneration desorption area and regeneration
Cooling zone, as one embodiment, processing moisture absorption area, regeneration desorption area and re-generatively cooled area are respectively 60 degree of sector regions, 60
Spend sector region and 240 degree of sector regions.It can handle moisture absorption area according to needed for actual conditions and be arranged to 30 to 90 degree fan sections
Domain, regeneration desorption area are arranged to 30 to 90 degree sector regions, and re-generatively cooled area is 240 degree to 300 degree.
Surface cooler (not shown) can be set in the upstream of runner heat exchanger 1, reduces energy consumption for cooling, and fresh air passes through surface cooler
Two-way is separated into after cooling.Fresh air temperature before by runner heat exchanger 1 is 12 degree, and fresh air is behind processing moisture absorption area all the way
It is warming up to 28 degree and is blown by handling blower fan 3.Another way fresh air by re-generatively cooled area heat exchange be warming up to 50 degree after, then with temperature
Mixed for 30 degree of regeneration fresh airs, then, successively by regenerating wind after regenerative heater 2 heats up and regenerated the heat exchange of desorption area
Machine 4 is discharged.
Compares figure 1 and Fig. 2 are understood, in the embodiment of the present invention, fresh air improves after the energy-conservation heat exchange in re-generatively cooled area
The absorption property of runner heat exchanger, also, be warming up to after 50 degree of fresh air mixes with 30 degree of regeneration fresh air, by re-generatively cooled
After the fresh air of area's heating mixes with outdoor regeneration fresh air, then 120 degree of process is warming up to by regenerative heater 2, with existing skill
Art is compared, and is substantially saved the heating energy consumption of more than about 20 degree of regenerative heater, is realized energy-saving improved purpose.
Some technical terms used in the present invention are intended merely to facilitate description, are not construed as limiting the invention,
The present invention is not limited to above-described preferable embodiment, the public affairs that can be known based on those skilled in the art
