Combination type air dehydrating unit
Technical field
The utility model relates to air dewetting technical field.
Background technology
Engine rooms of wind power generators or tower cylinder are the environment of a relative closure, in order to ensure the normal operation of wherein equipment, need to make the humidity and temperature that in cabin or tower cylinder, maintenance one is stable.At present, the mode of air dewetting mainly contains following several:
One, cooling and dehumidifying.Below Air flow to dew point, be that the hydrogenesis in air becomes drop, thus reduce the humidity of air.The machine of the method is used to have cooled dehumidifier unit.
Two, compression dehumidifying.Namely humid air compressed, cool, make the hydrogenesis in air, thus reduce the humidity of air.The method is applicable to the less occasion of air quantity, but is unwell to Wind Volume occasion.
Three, solid adsorption type dehumidifying.Namely adopt capillarity by water adsorption on solid moisture absorbent.Capillary can reduce dew point, but the equipment that when adsorption area is large, the method is used also can become large thereupon.
Four, liquid absorptive dehumidifying.Namely the spray absorber moisture of water lithium chloride solution is adopted.The shortcoming of the method is that equipment is comparatively large, and must change absorbing liquid.
Five, adsorption runner dehumidifying.The thin plate being about to dipping hygroscopic agent is processed into cellular runner, and ventilates to runner.Use the machine of the method to have rotary dehumidifier, rotary dehumidifier relatively simple for structure, can work at a lower temperature.
The rotation per hour 8 ~ 18 times under the driving of motor of the runner of rotary dehumidifier, runner is divided into moisture absorption district and renewing zone, moisture in air is after moisture absorption district is removed, dried air is sent into indoor by air blast, and the runner region absorbing moisture is when moving to renewing zone, moisture can be driven away from the regeneration air (warm air) of reverse feeding, thus realize the regeneration of runner.Like this, runner repeats moisture absorption and regeneration two actions continuously, thus provides dry air constantly.
At present, machine mainly cooled dehumidifier unit and the rotary dehumidifier of engine rooms of wind power generators or the dehumidifying of tower cylinder is applied to.But cooled dehumidifier unit is comparatively large by the temperature limiting of environment for use, and during General Requirements start, environment temperature is more than 15 DEG C, otherwise affects the operation of machine; And heat can be produced, the side effect that this part heat will certainly bring indoor temperature to raise during the rotary wheel regeneration of rotary dehumidifier, Electric heating when simultaneously regenerating also can increase energy consumption, and rotary dehumidifier cost is higher, uses continuously and easily damages.
In a word, in prior art, also lack that a kind of applicability is wide, few side effects, durable in use, dehydrating unit with low cost.
