As can be seen from the above description, the main fresh air path is an air flow path for removing a large amount of moisture in the external air and delivering the dried air to the area to be dehumidified, the external fresh air can be introduced into the dehumidifier under the driving of the processing fan 53 and the blower 55, then the impurities in the fresh air can be removed through the coarse filter 51, the dust is prevented from accumulating in the equipment to affect the service life of the parts, and most of the moisture in the air can be removed through the condensation of the front surface cooler 52 to reduce the workload of the two rotating wheels; finally, the condensation cooling through the middle surface cooler 54 and the rear surface cooler 56 not only can further ensure the integral dehumidification effect, but also can reduce the dehumidified high-temperature gas to the temperature meeting the daily requirements.
Further, the air outlet of the rear surface cooler 56 is communicated with the air inlet of the processing fan 53 through a pipeline 6.

Further, the first rotating wheel 3 and the second rotating wheel 4 are low-temperature dehumidification rotating wheels.
As is clear from the above description, the low-temperature dehumidifying rotor has the characteristic of being capable of realizing rotor regeneration even in the case of low heat, and the characteristic provides technical support for the overall reduction of the regenerative heater 8, so that the first rotor 3 can perform its own regeneration operation by using the heat generated during its own operation and the waste heat after the regeneration of the second rotor 4, thereby achieving the purpose of energy saving.

The energy-saving rotary dehumidifier can assist the air dehumidifying work.
Referring to fig. 1, a first embodiment of the present utility model is as follows:
an energy-saving rotary dehumidifier comprises a first rotary wheel 3, a second rotary wheel 4, a fresh air main path 5, a regenerative heater 8 and a regenerative fan 9; the regenerated wind sequentially passes through the regeneration zone of the second rotating wheel 4 and the regeneration zone of the first rotating wheel 3 to form a regeneration main path 1; a part of fresh air passes through the first rotating wheel 3 to form a first regeneration branch flow 2, and the air outlet end of the first regeneration branch flow 2 is communicated with the regeneration main path 1 between the first rotating wheel 3 and the second rotating wheel 4; a part of fresh air sequentially passes through the treatment fan 53 and the second rotating wheel 4 to form a second regeneration tributary 7; the second regeneration branch 7 is communicated with the regeneration main path 1 through a regeneration heater 8; the regenerating fan 9 and the regenerating main path 1 are respectively positioned at two ends of the first rotating wheel 3; the air inlet end of the regeneration fan 9 is communicated with the regeneration zone of the first rotating wheel 3; the first rotating wheel 3 and the second rotating wheel 4 are low-temperature dehumidification rotating wheels.

The working principle of the utility model is as follows:
fresh air dehumidifying stage: firstly, the external fresh air can be introduced into the dehumidifier under the drive of the processing fan 53, and impurities in the fresh air are removed through the coarse filter 51, so that dust is prevented from accumulating in the equipment to influence the service life of parts; the condensation by the front surface cooler 52 then removes most of the water in the gas, thus alleviating the workload of the two wheels (the first wheel 3 and the second wheel 4 play a role in deep dehumidification); finally, the dehumidified high-temperature gas is reduced to a temperature meeting daily requirements by the rear surface cooler 56, and the dry gas is conveyed into the region 10 to be dehumidified under the drive of the blower 55.
Because the air outlet of the rear surface air cooler 56 and the air inlet of the processing fan 53 are communicated with the region 10 to be dehumidified through the pipeline 6, the region 10 to be dehumidified and the rotary dehumidifier form a return air loop, so that the region 10 to be dehumidified can achieve the dehumidification effect, and the internal waste gas can be returned to the rotary dehumidifier to be mixed with fresh air, so that the effect of purifying the air is achieved.
And (3) a rotating wheel regeneration stage: firstly, a part of fresh air is conveyed to the regeneration heater 8 through the second regeneration branch 7, the temperature of the air flow in the second regeneration branch 7 can be further increased through the regeneration heater 8, so that the regeneration work of the second rotating wheel 4 is met, the regeneration heater 8 is also an indirect heat source of the regeneration work of the first rotating wheel 3, namely, the residual temperature of the air heated by the regeneration heater 8 and after the regeneration work of the second rotating wheel 4 is finished is still about 70 ℃, the temperature of the air flowing into the first regeneration branch 2 and processed by the first rotating wheel 3 reaches about 40 ℃, when the two air flows are mixed in the regeneration main path 1, the mixed air with the temperature of about 60 ℃ can be produced, because the first rotating wheel 3 is a low-temperature dehumidification rotating wheel (namely, the rotating wheel temperature can carry out the regeneration work when reaching 50 ℃), the temperature of the mixed air just meets the regeneration condition of the first rotating wheel 3, so that the dehumidifier can complete the rotating wheel regeneration work of the whole machine through only one regeneration heater 8, the energy consumption of the whole machine is obviously reduced, and the volume of the equipment is indirectly reduced.
In summary, the energy-saving rotary dehumidifier provided by the utility model has the advantages of simple overall structure and convenience in operation; when the part of gas which flows into the first regeneration branch and is subjected to the first rotating wheel treatment to ensure that the temperature is raised to a certain extent is mixed with the waste heat gas in the regeneration main path after the second rotating wheel regeneration work is completed, the temperature of the mixed gas can just meet the regeneration condition of the first rotating wheel; the rotating wheel dehumidifier overcomes the defects that the existing rotating wheel dehumidifier can complete the rotating wheel regeneration of the whole machine only by arranging heat sources in the regeneration areas of all the rotating wheels, thereby increasing the energy consumption of equipment.
