Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, system casing 11 is divided into two chambers, centre is separated by dividing plate and desiccant wheel 10, one of them indoor regeneration air air inlet 1 that is provided with, regeneration blower fan 6, heater 7, dry air centrifugal blower 8 and dry air air outlet 5, another indoor regeneration air air outlet 2 that is provided with, process air air inlet 3 and cooler 4, regeneration air air inlet 1 connects regeneration blower fan 6 successively by pipeline, heater 7, the regeneration air region of desiccant wheel 10, regeneration air air outlet 2, process air air inlet 3 and connect successively cooler 4 by pipeline, the processing air section of desiccant wheel 10, dry air centrifugal blower 8 and dry air air outlet 5, dry air air outlet 5 connects high-voltage board bottom air entrance by gas pipeline 12, at described regeneration air air inlet 1 and processing air air inlet 3, air filter unit is set respectively.System control box 9 is also set on system casing 11, includes controller, system control box 9 is connected to CD-ROM drive motor, regeneration blower fan 6, heater 7, dry air centrifugal blower 8, the cooler 4 of described desiccant wheel 10 by cable.
The clean dry air switching system of high-voltage board of the present utility model adopts honeycomb rotor dehumidifier, comprise that the corrugated medium of being made by special composite heat resistance material (ceramic silica gel) forms, and be loaded with the cellular dry runner of drier, runner when rotated, continue to repeat moisture absorption regeneration action, do not affect Air Flow, the dry air of ultralow dew point is continuously provided.Desiccant wheel is divided into Liang Ge district by the dividing plate that contains high density packing material: processing air section is the sector region of 270 degree; Regeneration air region is 90 degree sector regions.
Desiccant wheel, in dehumidification process, constantly slowly rotates.When processing the runner 270 degree covering of the fans of air section, absorb or adsorbed hydrone, becoming after saturation condition, by being automatically brought to the 90 degree covering of the fans in regeneration air region, entering regenerative process.In regenerative process, regeneration air, after heating, enters rotary wheel regeneration district covering of the fan, and under the condition of high temperature, the hydrone of runner absorption or absorption, by desorption, is lost in regeneration air.Regeneration air is owing to having distributed heat in desorption process, and self temperature reduces, and has become the larger humid air of water capacity.Humid air is drained into outside high-voltage board by regeneration blower fan.
In the regenerative process of dehumidifying limit, above-mentioned limit, air constantly dehumidifies, and runner is constantly reproduced, so repeatedly, and continuous dehumidifying.The rotating speed of runner is very slow, generally 12~24 turning/hour rotational speed, energy consumption is minimum, the water capacity of processing air can be lower than 0.0007g/kg.
Through rotary dehumidifier dehumidifying, can remove in air 70% humidity, the dew point of the outlet air of rotary dehumidifier is lower 10~15 ℃ than the dew point of inlet air, can ensure that cabinet inner drying is without moisture, and avoids equipment oxidation.By continual, in high-voltage board, carry dry air (gas pushing quantity per hour is 8~10 times of high-voltage board volume), guarantee that the relative cabinet of cabinet inner air pressure is malleation outward, even if consider the leakage of the pressure release hole on cabinet surface, the dry air of sending into still can utilize gap and the hole of each bin dividing plate in cabinet, from arrival switch gear room, cable vault, secondary device chamber and the bus-bar room of bottom, guarantee in high-voltage board without dead angle.
Workflow is:
1, through regeneration blower fan, 6 superchargings enter heater 7 to regeneration air, and then air heat enters desiccant wheel 90 degree sector regions to 120 degree left and right, and the systemic moisture of desiccant wheel 10 is taken out of by high temperature air, by regeneration air air outlet 2, discharges.
2, the humid air in high-voltage board enters into cooler 4 through processing air air inlet 3, humid air is cooled to 9 degree left and right, then enter desiccant wheel 270 degree sector regions, by desiccant wheel 10 by the moisture absorption in humid air (in embodiment runner constantly slowly rotate 15~18 turn/hour), the dry air that goes out desiccant wheel 10 enters gas pipeline by dry air air outlet 5 after centrifugal blower 8 superchargings, then enters high-voltage board bottom inlet.
This method effect on moisture extraction is obvious, can obviously reduce relative humidity and dew point temperature in cabinet, avoids the generation of condensation, and decapacitation reduces air humidity, prevents from, outside condensation generation, can also effectively preventing equipment component oxidation; Operating temperature range is wide, can, under subzero 30 ℃ of states, continue to carry out dehumidifying work.
As shown in Figure 2, system is also included in the Mobile centrifugal blower fan arranging in high-voltage board, described Mobile centrifugal blower fan comprises the centrifugal blower of cabinet 14 and cabinet 14 inside, cabinet 14 bottoms have roller 16, cabinet 14 bottoms have air inlet 14-1, are connected to high-voltage board bottom air entrance, and cabinet 14 sides have air outlet 14-2, Temperature Humidity Sensor 15 is installed on cabinet 14, and described centrifugal blower and Temperature Humidity Sensor 15 are all connected to system control box 9 by cable; By the real-time testing environment humiture of Temperature Humidity Sensor 15, when ambient temperature and humidity reaches alarming value, start centrifugal blower, air is entered to cabinet 14 inside through bottom air inlet mouth 14-1, then by centrifugal blower supercharging, air is blown to body surface by air outlet 14-2 high pressure.
Described gas pipeline 12 has a plurality of gas outlets, and each gas outlet is provided with adjustable valve 13, and the control end of each adjustable valve 13 is connected to system control box 9.According to the distance with air outlet from the near to the remote, described adjustable valve 13 is opened, aperture is ascending.As shown in Figure 3, in embodiment, gas pipeline 12 length is 50 meters, has 5 air outlets, is respectively equipped with an adjustable valve 13,0.4 meter of valve maximum opening.By Distance Gas Pipeline air outlet from the near to the remote, 5 adjustable valves are opened, the opening of opening valve is respectively 60%, 70%, 80%, 90%, 100%, can guarantee to greatest extent that like this air output of each gas outlet is balanced when gas pipeline is supplied gas.
Therefore, the utility model has been applied in the process that cellular silica gel runner carries out moisture absorption synchronously the processed of regenerating of the adsorbent after moisture absorption, can be recycled, whole moisture absorption work can be carried out continuously, overcome compressor-type dehumidifier (just can not work below for about 10 ℃) can not continuous dehumidifying and in low temperature and low humidity situation helpless shortcoming.This system can be operated under subzero 30 ℃ of states, can continue dehumidifying work; Dew point that cooling and dehumidifying mode cannot the realize dry air in the ultralow humidity below 10 ℃ can be provided continuously.The utility model is simple in structure, and drive control part is simple, only needs desiccant wheel, regeneration heater and forced draft fan running, can obtain dry air, so simple to operate.In addition, it belongs to dry type dehumidification type, and without supplementary hygroscopic agent, maintenance guarantee is convenient; Under clean air ambient, the performance of desiccant wheel can decline or degenerate hardly, can be competent at continuous operation all the year round.
