Description
(1) technical field
The utility model relates to drying system, is specially low dew point removal moisture drying system.
(2) background technology
The structure of existing low dew point removal moisture drying system is seen Fig. 1, its course of work is as follows: outdoor new wind is by filter 2, cooler 3,4 and blower fan 5 after, a part is passed through the dehumidifying district 11 of desiccant wheel 6 after in subcooler 7 inlet chambers, another part enters the cooling zone 12 of desiccant wheel 6 after pervaporation device 9 enters the renewing zone 13 of desiccant wheel, arrive outdoor through blower fan 10 back parts again, another part returns evaporimeter 9, indoor wind enters the cooler 4 in air channel 1 again by pipeline 8, guarantee removal moisture drying when so going round and beginning again the circulation of realization room air, thereby make room air meet the requirements of dew point room air.There are two shortcomings in this system: one is exactly that adjustability is poor, the air-out dew point is about-45 degrees centigrade, the mode that needs to strengthen the desiccant wheel area improves effect on moisture extraction, if installed this drying system, when needs increase promptly lower air-out dew point of moisture removal and big air quantity, then need to change or increase equipment; Another shortcoming is exactly the effect instability of dehumidifying, because the temperature of outdoor new wind and humidity all changing, also just has fluctuation accordingly through its temperature and humidity behind one desiccant wheel, thereby causes indoor dew point fluctuation.
(3) summary of the invention
At the unsettled shortcoming of effect of existing low its adjustability difference of dew point removal moisture drying system and dehumidifying, the utility model provides another low dew point removal moisture drying system, and adjustability better, the effect of dehumidifying is more stable.
The technical solution of the utility model is such: it comprises air channel 1, air channel 1 filter 2 that is linked in sequence, cooler 3, blower fan 4, the dehumidifying district 7 of desiccant wheel 6, cooler 10 and control valve 11, the outlet of blower fan 4 is connected with the cooling zone 8 of desiccant wheel 6 by branch air duct 5 and communicates, it is characterized in that: the air inlet in air channel 1 connects auxiliary system, described auxiliary system comprises air channel 35, described air channel 35 control valve 31 that down the wind is linked in sequence, filter 30, cooler 29, cooler 27, blower fan 26, the dehumidifying district 22 of desiccant wheel 21, control valve 17, the outlet side in the dehumidifying district 22 of desiccant wheel 21, air channel 35 connects subtube a, b, the subtube b cooler 14 that has been linked in sequence, check-valves 15, the renewing zone 9 of desiccant wheel 6, blower fan 16, control valve 28, the outlet side of control valve 28, subtube b and air channel 35 be positioned at cooler 29, position between the cooler 27 connects, and subtube a is equipped with control valve 12 and is connected with the outlet of the cooling zone 8 of desiccant wheel 6 and communicates; With on the air-return duct 32 that the air inlet in air channel 1 is connected control valve 33 is installed; Renewing zone 23 its entrance and exits of desiccant wheel 21 connect intake stack 18 and exhaust duct 25 respectively, and intake stack 18 down the wind is equipped with heater 19 and check-valves 20 successively; Exhaust duct 25 is equipped with blower fan 24.
When the utility model is installed on engineering, with air channel 35,25,18 end is received outdoor, the air inlet in air channel 32, the air outlet in air channel 1 is installed on indoor respectively, so new wind enters pipeline 35 backs and handles through desiccant wheel 21 jointly with regeneration wind, pending under the relatively little situation of humidity, give the host computer system of low dew point rotary wheel dehumidifying and replenish new wind, the water capacity of wind that enters desiccant wheel 6 like this is lower than corresponding water capacity in the existing apparatus, the outlet dew point of corresponding desiccant wheel 6 is lower than the outlet dew point in the existing apparatus, when needs increase promptly lower air-out dew point of moisture removal and big air quantity, can increase the intake in air channel 35, the face velocity that improves desiccant wheel 21 gets final product: and outdoor new wind is through the dehumidifying of double desiccant wheel, the fluctuation of outdoor new wind temperature and humidity is less to the influence of indoor dew point, and effect on moisture extraction is more stable.
