Description

Technical Field

[0001] This utility model relates to the field of rotary dehumidifiers, and more particularly to a rotary dehumidifier with dual-channel regeneration and partitioning processing. Background Technology

[0002] Rotary dehumidifiers provide a stable, low-humidity environment for manufacturing workshops and are widely used in industries such as food, pharmaceuticals, bridge construction, military, aerospace, and lithium batteries. Currently, traditional rotary dehumidifiers on the market use a single-channel rotor design: the front rotor serves as both the treatment and regeneration zones, while the rear rotor combines these zones into a single treatment zone, a cooling zone, and another regeneration zone, each with its own single channel. The primary function of the regeneration zone is to desorb and discharge the saturated moisture adsorbed in the treatment zone using high-temperature, dry regeneration air.

[0003] Rotary dehumidification is a heat and moisture exchange process. The treatment zone of the rotor adsorbs moisture from the air onto the substrate (rotary adsorption treatment), while the regeneration zone adsorbs moisture from the substrate onto the rotor (rotary desorption regeneration). Different temperatures and humidity levels affect the regeneration zone differently. The initial zone, immediately after the rotor enters the regeneration zone, has a very high moisture content; direct regeneration using unheated, room-temperature dry air achieves desorption. In the later regeneration zone, after desorption and regeneration in the initial zone, the moisture content gradually decreases, and high-temperature dry air provides better treatment. Traditional single-channel treatment cannot achieve effective rotor desorption and regeneration; it requires uniform heating of the regeneration air in each channel, resulting in high energy consumption. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rotary dehumidifier with dual-channel regeneration zone processing that achieves both the treatment effect of rotary desorption and regeneration and saves regeneration energy consumption.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a rotary dehumidifier with dual-channel regeneration and zoned processing, including a dehumidification rotor, a processing air path, and a regeneration air path. The dehumidification rotor is provided with a processing zone, a regeneration wet zone, and a regeneration dry zone along its rotation path. The processing air path is connected to the regeneration air path, and the regeneration air path is connected to the outside. The processing air path passes through the processing zone, and the regeneration air path includes a high-temperature air path and a drying air path. The high-temperature air path and the drying air path pass through the regeneration dry zone and the regeneration wet zone, respectively.

[0006] Furthermore, a regenerative heater is provided on the high-temperature air path.

[0007] Furthermore, a temperature sensor is provided on the high-temperature air path, and the temperature sensor is electrically connected to the regenerative heater.

[0008] Furthermore, two sets of temperature and humidity sensors are respectively provided on both sides of the dehumidification rotor in the high-temperature air path.

[0009] Furthermore, both the processing air path and the regeneration air path are equipped with blowers.

[0010] Furthermore, an air flow meter is installed on the regeneration air path, and the air flow meter is electrically connected to the blower.

[0011] Furthermore, both the drying air path and the high-temperature air path are equipped with air valves.

[0012] Furthermore, the processing air path includes a fresh air path, which is connected to the regeneration air path; the dehumidifying impeller includes a first impeller, which has a first processing zone, a first regeneration wet zone, and a second regeneration dry zone respectively arranged on its rotation path along its rotation direction; the fresh air path passes through the first processing zone; the regeneration air path includes a first high-temperature air path and a first drying air path; the first drying air path passes through the first regeneration wet zone; and the first high-temperature air path passes through the first regeneration dry zone.

[0013] Furthermore, the processing air path also includes a return air path, the air inlet and exhaust ends of which are connected to the fresh air path; the dehumidifying impeller also includes a second impeller, which has a second processing zone, a second regeneration wet zone and a second regeneration dry zone respectively arranged on its rotation path along its rotation direction, the return air path passes through the second processing zone, and the regeneration air path also includes a second high-temperature air path and a second drying air path, the second drying air path passes through the second regeneration wet zone and the second high-temperature air path passes through the second regeneration dry zone.

[0014] Furthermore, the second rotor is provided with a second processing zone, a second regeneration wet zone, a second regeneration dry zone and a cold blowing zone along its rotation path in the direction of rotation. The regeneration air path also includes an air inlet path, which passes through the cold blowing zone and is connected to the second high-temperature air path and the second drying air path.

[0015] The beneficial effects of this invention are as follows: Based on the zoning of the dehumidifying rotor's regeneration zone into dry and wet sections, room-temperature (unheated) dry (low moisture content) regeneration air is used for desorption in the wet regeneration zone. After desorption in the wet regeneration zone, the dehumidifying rotor rotates into the dry regeneration zone, where high-temperature dry regeneration air is used for further desorption. By zoning the rotation of the dehumidifying rotor, high-temperature dry regeneration air from the high-temperature air path and dry regeneration air from the room-temperature dry air path are used to dehumidify and desorb in the dry and wet regeneration zones respectively. This allows for efficient and targeted zoning and desorption regeneration of the dehumidifying rotor. Compared to traditional desorption and regeneration without zoning, this effectively reduces the amount of high-temperature dry regeneration air and the energy consumption of the corresponding components.

[0026] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figure 1 A rotary dehumidifier with dual-channel regeneration and zoned processing includes a dehumidification rotor, a processing air path, and a regeneration air path 2. The dehumidification rotor has a processing zone, a regeneration wet zone, and a regeneration dry zone respectively arranged along its rotation path in its rotation direction. The processing air path is connected to the regeneration air path 2, and the regeneration air path 2 is connected to the outside. The processing air path passes through the processing zone. The regeneration air path 2 includes a high-temperature air path and a drying air path, which pass through the regeneration dry zone and the regeneration wet zone respectively.

[0028] As can be seen from the above description, the beneficial effects of this utility model are as follows: Based on the phenomenon of dry and wet partitioning in the dehumidifying rotor regeneration zone, room temperature (unheated) dry (low moisture content) regeneration air is used for desorption in the wet regeneration zone. After desorption in the wet regeneration zone, the dehumidifying rotor rotates into the dry regeneration zone, where high-temperature dry regeneration air is used for further desorption. By partitioning the rotation of the dehumidifying rotor, high-temperature dry regeneration air from the high-temperature air path and dry regeneration air from the room temperature dry air path are used to dehumidify and desorb in the dry and wet regeneration zones respectively. This allows for efficient and targeted partitioned desorption and regeneration of the dehumidifying rotor. Compared with traditional desorption and regeneration without partitioning, this effectively reduces the high-temperature dry regeneration air volume and the energy consumption of the corresponding components.

[0029] Furthermore, a regenerative heater is provided on the high-temperature air path.

[0030] As described above, the incoming regeneration air is heated by the regeneration heater on the high-temperature air path, and then passed through the regeneration dry zone of the dehumidification rotor to desorb and regenerate the dehumidification rotor in a high-temperature dry state.

[0031] Furthermore, a temperature sensor is provided on the high-temperature air path, and the temperature sensor is electrically connected to the regenerative heater.

[0032] As described above, the temperature of the regenerated air after passing through the regenerator is monitored by a temperature sensor and fed back to the control component for temperature regulation of the regenerator.

[0033] Furthermore, two sets of temperature and humidity sensors are respectively provided on both sides of the dehumidification rotor in the high-temperature air path.

[0034] As described above, the temperature and humidity at the inlet of the regenerator and the outlet of the dehumidifier are monitored by the arrangement of temperature and humidity sensors, and the feedback is sent to the control component to regulate the regenerator and other components.

[0035] Furthermore, both the processing air path and the regeneration air path 2 are equipped with blowers.

[0036] As can be seen from the above description, the design of the blower ensures that the processing air path and the regeneration air path 2 have sufficient air volume.

[0037] Furthermore, an air flow meter is installed on the regeneration air path 2, and the air flow meter is electrically connected to the blower.

[0038] As described above, the air flow meter is used to monitor the air volume in the regeneration air path 2 and feed it back to the control component to regulate the blower.

[0039] Furthermore, both the drying air path and the high-temperature air path are equipped with air valves.

[0040] As described above, the regenerated air volume is regulated by the air valve.

[0041] Furthermore, the processing air path includes a fresh air path 1, which is connected to the regeneration air path 2; the dehumidification impeller includes a first impeller 4, which has a first processing zone 41, a first regeneration wet zone 42, and a first regeneration dry zone 43 respectively arranged on its rotation path along its rotation direction; the fresh air path 1 passes through the first processing zone 41; the regeneration air path 2 includes a first high-temperature air path 25 and a first drying air path 26; the first drying air path 26 passes through the first regeneration wet zone 42; and the first high-temperature air path 25 passes through the first regeneration dry zone 43.

[0042] As described above, the fresh air from the fresh air path 1 enters the room after being dehumidified and heat-exchanged in the first treatment zone 41 of the first rotor 4, and then enters the regeneration air path 2. Through the diversion of the high-temperature air path and the dry air path in the regeneration air path 2, the high-temperature dry regeneration air and the normal-temperature dry regeneration air enter the first regeneration dry zone 43 and the first regeneration wet zone 42 of the first rotor 4 respectively, to perform desorption and regeneration operation on the first rotor 4.

[0043] Furthermore, the processing air path also includes a return air path 3, the air inlet and exhaust ends of which are connected to the fresh air path 1; the dehumidification impeller also includes a second impeller 5, the second impeller 5 having a second processing zone 51, a second regeneration wet zone 52 and a second regeneration dry zone 53 respectively arranged on its rotation path along its rotation direction, the return air path 3 passing through the second processing zone 51, the regeneration air path 2 also includes a second high-temperature air path 22 and a second drying air path 23, the second drying air path 23 passing through the second regeneration wet zone 52, and the second high-temperature air path 22 passing through the second regeneration dry zone 53.

[0044] As described above, the fresh air from the fresh air path 1 enters the return air path 3 after being dehumidified and heat-exchanged in the first treatment zone 41 of the first rotor 4. The fresh air from the return air path 3 is further dehumidified and heat-exchanged in the second treatment zone 51 of the second rotor 5 before entering the room. Afterward, part of it enters the regeneration air path 2 as regeneration air, and part of it continues to enter the return air path 3 as return air. The regeneration air entering the regeneration air path 2 is split by the second high-temperature air path 22 and the second dry air path 23 of the regeneration air path 2, and enters the second regeneration dry zone 53 and the second regeneration wet zone 52 of the second rotor 5 as high-temperature dry regeneration air and room-temperature dry regeneration air, respectively, to perform desorption and regeneration operation on the second rotor 5.

[0045] Furthermore, the second rotating wheel 5 is provided with a second processing zone 51, a second regeneration wet zone 52, a second regeneration dry zone 53 and a cold blowing zone 54 along its rotation path in the direction of rotation. The regeneration air path 2 also includes an air inlet path, which is connected to the second high temperature air path 22 and the second drying air path 23 through the cold blowing zone 54.

[0046] As described above, the regenerated air entering the regenerated air path 2 first passes through the cold blowing zone 54 of the second rotor 5 for temperature and humidity exchange, and then enters the second high-temperature air path 22 and the second dry air path 23 of the regenerated air path 2.

This allows for highly efficient and targeted zoned desorption and regeneration of the dehumidifier rotor.
