As shown in fig. 1, a schematic structural diagram of a multi-dew-point air supply rotating wheel dehumidification system in an embodiment of the present utility model is shown, including a front rotating wheel treatment air section 1, a first dew-point air supply section 2, a rear rotating wheel treatment air section 3 and a second dew-point air supply section 4, wherein the front rotating wheel treatment air section 1, the rear rotating wheel treatment air section 3 and the second dew-point air supply section 4 are sequentially arranged along a wind direction, and an outlet is arranged through an air outlet path of the front rotating wheel treatment air section to lead out the first dew-point air supply section 2.

The front rotating wheel treatment wind section 1 is positioned on the wind inlet path and is used for carrying out cooling and dehumidifying treatment on the wind inlet to reach a first dew point temperature; the front rotating wheel is used for processing the air outlet path of the air section, and the original air outlet path is divided into a main air outlet path and an auxiliary air outlet path by arranging an outlet.

It should be noted that the dew point temperature is different from the conventional temperature, and the temperature is generally referred to as an air temperature, and the air temperature represents the air cooling and heating degree in the weather, which is simply referred to as air temperature. And dew point temperature refers to the temperature at which air cools to saturation without changing both moisture content and air pressure. It is said that the temperature at which the water vapor in the air becomes dew is called dew point temperature. When the water vapor in the air is saturated, the air temperature is the same as the dew point temperature; when the water vapor is not saturated, the air temperature must be above the dew point temperature. The difference between the dew point and the air temperature may be indicative of the degree to which the moisture in the air is saturated from the distance.

It should be noted that in an actual industrial production process workshop, different products and different process procedures have different temperature and humidity requirements, so that multiple types of rotary dehumidifier needs to be installed to meet different production environment requirements. However, installing multiple types of rotary dehumidifier causes problems of high investment and operation costs. Therefore, in order to save the cost, based on different dew point temperatures of the wind after the front rotating wheel and the rear rotating wheel are respectively processed, the embodiment provides a system capable of respectively leading out the wind with different dew point temperatures from the outlet ends of the front rotating wheel and the rear rotating wheel so as to select proper wind according to actual production requirements.

Specifically, in the traditional double-rotating-wheel dehumidifier, the dew point temperature of wind treated by the front rotating wheel is lower than-10 ℃ after the wind is treated by the rear rotating wheel. Wherein the dew point temperature of the wind after the treatment of the front rotating wheel is more than-10 ℃, and the dew point temperature of the wind after the treatment of the rear rotating wheel is less than or equal to-10 ℃. In this embodiment, an outlet is disposed on the air outlet path of the front runner processing air section, and the air outlet path of the front runner processing air section can be divided into two air outlet paths, namely a main air outlet path and an auxiliary air outlet path, based on the connection of the outlet and the air pipe. The front runner treatment wind section 1 carries out cooling and dehumidifying treatment on the inlet wind to reach the first dew point temperature, then the wind outputting the first dew point temperature through the main wind outlet path enters the next stage, and the wind outputting the first dew point temperature through the auxiliary wind outlet path carries out wind supply.

The first dew-point air supply section 2 is located on the auxiliary air outlet path, and is used for performing temperature adjustment treatment on the air with the first dew-point temperature discharged from the front rotating wheel treatment air section and supplying air.

The second dew-point air supply section 4 is located on the air outlet path of the rear rotating wheel processing air section and is used for performing temperature adjustment processing on the air with the second dew-point temperature and supplying air. And the air at the second dew point temperature on the air outlet path of the rear rotating wheel treatment air section is sent to the second dew point air supply section 4, the temperature of the air at the second dew point temperature is regulated, and the air is supplied to a process vehicle or other application places through an air outlet of the second dew point air supply section.

It should be noted that, the filter in the dehumidification system can purify the gas by the action of the porous filtering material, so as to ensure the air cleanliness of the process workshop or other application places, and the filter is divided into a primary filter and a medium-efficiency filter according to the filtering effect. The primary filter is a simple and basic filter, has the filtering efficiency lower than 90 percent, and mainly comprises a primary plate filter, a primary folding filter, a primary bag filter, a metal mesh regenerated filter and the like. The filtration efficiency of the medium-efficiency filter is between 90% and 95%, and the medium-efficiency filter mainly comprises a medium-efficiency bag filter, a glass fiber filter and the like. Compared with the primary filter, the medium-efficiency filter has better and more stable filtering effect and longer service life.

Specifically, the main function of the front rotating wheel treatment wind section is to cool and dehumidify the inlet wind to reach the first dew point temperature. Along the air inlet direction, the air inlet firstly passes through the primary filter 11 to remove part of impurities and then enters the front surface cooler 12, the front surface cooler 12 is utilized to cool and dehumidify the air inlet, the temperature and humidity of the air inlet are controlled, the air inlet reaches a relatively low-temperature and low-humidity state and then enters the front rotating wheel 13, the surface of the front rotating wheel is coated with a moisture absorbent, and the surface of the front rotating wheel is provided with a honeycomb multi-pore channel, so that the moisture in the wet air flowing through the front rotating wheel can be adsorbed through slowly rotating the front rotating wheel, and the air inlet is drier and finally reaches the first dew point temperature. The water flow of the front surface cooler 12 can be adjusted through the first adjusting valve 121 to control the temperature of the front surface cooler 12, so that cooling of the inlet air is achieved.

In an embodiment, the rear runner treatment wind section 3 is provided with a treatment fan 31, an intermediate cooler 32 and a rear runner 33 in sequence along the wind direction; the treatment fan 31 is used for sending wind with a first dew point temperature to the intercooler 32; the intermediate cooler 32 is used for cooling the wind with the first dew point temperature; the rear wheel 33 dehumidifies the wind at the first dew point temperature; wherein, the middle cooler 32 is provided with a second regulating valve 321; the second regulating valve 321 is used for regulating the water flow of the intercooler 32.

Specifically, in the post-rotating wheel treatment wind section 3, wind with the first dew point temperature is subjected to cooling and dehumidifying treatment so as to reach the second dew point temperature. Along the main air outlet path direction of the front rotating wheel treatment air section, the treatment fan 31 sends air with the first dew point temperature to the intercooler 32, the intercooler 32 is used for adjusting the water flow of the intercooler 32 through the second adjusting valve 321 to control the temperature of the intercooler 32, so that the air with the first dew point temperature is cooled and then enters the rear rotating wheel 33, and the rear rotating wheel 33 dehumidifies the air with the first dew point temperature to finally reach the second dew point temperature.

In one embodiment, the front wheel treatment wind section 1 comprises at least a neutral filter 14; the rear runner treatment wind section 3 at least comprises a treatment fan 31, an intermediate cooler 32 and a rear runner 33; the processing fan 31, the middle cooler 32 and the rear rotating wheel 33 are sequentially arranged along the wind direction; the installation position of the outlet includes any of the following positions, which are described with reference to fig. 1, 2 and 3:

position one: located between the neutral filter 14 and the process fan 31, as indicated at a in fig. 1. And at the point A, partial air with the first dew point temperature is led out to a process workshop or other user places through the air outlet connecting air pipe.

Position two: between the process fan 31 and the intercooler 32, as shown at point B in fig. 2. And B, connecting an air pipe through the outlet at the point B to lead out part of air with the first dew point temperature to blow to a process workshop or other user places.

Position three: located between the intermediate cooler 32 and the rear runner 33, as indicated at C in fig. 3. And C, connecting the air pipe at the outlet to lead out part of air with the first dew point temperature to blow to a process workshop or other user places.

In this embodiment, when the outlet is provided at the first or second position: the first dew-point air supply section 2 is provided with a temperature-adjusting surface cooler 22; the air with the first dew point temperature passes through the temperature-adjusting surface cooler 22 and then is sent to the temperature-adjusting heater 23 in the first dew point air supply section; wherein, the temperature-adjusting surface cooler 22 is provided with a third adjusting valve 221; the third regulating valve 221 is used for regulating the water flow of the temperature-regulating surface cooler 23. In the case where the outlet is provided at the third position: the first dew-point air supply section 2 is not provided with a temperature-adjusting surface cooler; the air at the first dew point temperature passes through the intercooler 32 and is then sent to the temperature-adjusting heater 23 in the first dew point air supply section.

It should be noted that, when the outlet is disposed at the first or second position, that is, when the outlet is at the position a shown in fig. 1 or the position B shown in fig. 2, the air at the first dew point temperature is not passed through the intercooler as in the case of the third position, and because the air at the first dew point temperature needs to be cooled during the air supply process of the first dew point air supply section. Therefore, when the position of the outlet is located at the point A or the point B, the temperature-adjusting surface cooler 22 is arranged in the first dew-point air supply section 2, and the air with the first dew-point temperature is cooled by the temperature-adjusting surface cooler 22; when the position of the outlet is positioned at the point C, a temperature-adjusting surface cooler is not required to be arranged, and the temperature of the air is reduced by the air at the first dew point temperature of the surface cooler.

It should be emphasized that the wind with different dew point temperatures is led out from the outlets of the front rotating wheel and the rear rotating wheel respectively, so as to be used in places with different production process requirements, so that the investment cost of the rotating wheel dehumidifying equipment and the installation and arrangement places thereof can be greatly reduced, the quantity of the rotating wheel dehumidifier equipment is reduced, the operation and maintenance management is facilitated, and the operation and maintenance cost in the operation and use process is reduced.

In an embodiment, the first dew point air supply section 2 is further provided with a first air supply device 21 and a temperature-adjusting heater 23; the first air supply device 21 is used for supplying air with a first dew point temperature; the temperature-regulating heater 23 is used for regulating the temperature of the wind at the first dew point temperature. Preferably, the first air supply device is an air blower or a regulating air valve.

It should be explained that, for the wind of the first dew point temperature led out from the wind section of the front rotating wheel, the wind is heated and regulated so that the temperature reaches the preset temperature and then is sent to a process vehicle or other user places through the air supply pipeline, so that the temperature regulating heater is arranged in the first dew point air supply section 2, and the wind of the first dew point temperature is heated to the required preset temperature by the temperature regulating heater and then is discharged.

It should be noted that, when the first air supply device is an adjusting air valve, the position setting of the outlet includes two cases: the position of the outlet is located between the processing fan and the intercooler or between the intercooler and the rear wheel, i.e. in connection with fig. 2 and 3. Because the air valve is mainly used for controlling the flow direction of the air, and the pressure of the air supplied by the blower is higher, if the first air supply device is the air valve, the pressure of the air supplied by the air supply device must be increased by the processing fan to supply the air to a process plant or other user places, and therefore, the position of the outlet needs to be arranged behind the processing fan, that is, the outlet is located between the processing fan and the middle cooler or between the middle cooler and the rear rotating wheel.

In one embodiment, the second dew-point air supply section 4 is provided with a second air supply device 41, a rear surface cooler 42, a heater 43 and a high efficiency filter (not shown) in sequence along the air direction; the second air supply device 41 is configured to supply air at a second dew point temperature; the rear surface cooler 42 is used for cooling the wind with the second dew point temperature; the heater 43 is used for adjusting the temperature of the wind at the second dew point temperature; the high-efficiency filter is used for filtering wind with the second dew point temperature; wherein, the rear surface cooler 42 is provided with a fourth regulating valve 421; the fourth regulating valve 421 is used for regulating the water flow of the rear surface cooler 42.

It is noted that the high-efficiency filter has extremely high filtering effect, and the filtering efficiency reaches more than 99 percent, and the high-efficiency filter comprises a baffle high-efficiency filter and a baffle-free high-efficiency filter. The dehumidification system in this embodiment uses primary filter, well effect filter and high-efficient filter simultaneously, can play the guard action, filters the partial impurity in the air earlier through primary filter and well effect filter, then protects high-efficient filter in order to prolong its life to ensure that the dehumidification function normally works.

The throttle valve 51 is used for adjusting the fluid flow in the condenser, the condensation heat of the condenser 52 is used for heating the fresh air in the regeneration wind section, and the refrigeration compressor 53 is used for cooling the fresh air. The fresh air blown into the regeneration wind section enables the moisture absorbed in the rotating wheel to be desorbed, and the wet air carrying away the moisture of the rotating wheel is discharged outdoors, so that the rotating wheel recovers the moisture absorption capacity to complete the regeneration process. The adoption of the regeneration wind section can be selected according to actual conditions, and will not be described in detail in this embodiment.
