The following modes of use are possible:

first, dry-type used alone: the third fan can be opened, the first fan and the second fan are closed, the first sealing door and the third sealing door are opened, and the second sealing door is closed. At this time, the air enters from the first ventilation opening 43, passes through the plate-shaped dry heat exchanger 2, enters the lower chamber 42, and is then directly discharged from the third ventilation opening 45.

Second, when wet alone: the third fan can be opened, the first fan and the second fan are closed, the second closing door and the third closing door are opened, and the first closing door is closed. At this time, the wind enters from the second ventilation port 44 at the lower chamber 42, passes through the plate-shaped wet heat exchanger 3, enters the lower chamber 42, and then is directly discharged from the third ventilation port 45. The dry type single use mode and the wet type single use mode can effectively reduce wind resistance.

Third, dry and wet tandem use: the third fan can be closed, the first fan or the second fan is opened (can be correspondingly selected according to the serial wind direction requirement), the first sealing door and the second sealing door are both opened, and the third sealing door is closed. If the first fan is on, the second fan is off, and at this time the wind enters from the second ventilation opening 44 at the lower chamber 42, passes through the plate-shaped wet heat exchanger 3, then enters the lower chamber 42, then passes through the plate-shaped dry heat exchanger 2, then enters the upper chamber 41, and then is discharged from the first ventilation opening 43. It is of course also possible to discharge from the second vent 44 at the upper chamber 41, in which case the combined heat and dry heat exchange apparatus may not be provided with the first vent 43, and the combined heat and dry heat exchange apparatus may be provided with the first vent 43 replaced by the second vent 44 provided at the upper chamber 41. If the second fan is opened, the first fan is closed, and the wind body flows in the opposite direction.

Fourth, dry and wet parallel use: the third fan may be turned on, the first fan and the second fan may be turned off, and the first closing door, the second closing door and the third closing door may be turned on. At this time, a part of the air enters from the first ventilation opening 43, passes through the plate-shaped dry heat exchanger 2, enters the lower chamber 42, and is directly discharged from the third ventilation opening 45; another part of the wind enters from the second ventilation opening 44 at the lower chamber 42, passes through the plate-shaped wet heat exchanger 3, enters the lower chamber 42, and then is directly discharged from the third ventilation opening 45.

Through the arrangement, the device has the advantages that the structure is simple, a complex channel is not needed, and various communication modes can be selected, so that the device is better suitable for corresponding use environments.

In some embodiments, the third tuyere may also be used as a fresh tuyere. When the ventilating channel of the plate-shaped dry heat exchanger and the ventilating channel of the plate-shaped wet heat exchanger are in a serial state, the ventilating efficiency is difficult to meet the requirement because of primary wind resistance, and the third wind port is opened at the moment to supplement wind at the middle part, but the third wind port with proper size is selected correspondingly according to the working efficiency of the fan and the wind resistance of the ventilating channel, so that the ventilating channel positioned at the front section is short-circuited due to excessive wind supplement.

When the air body flows from the ventilation channel of the plate-shaped wet heat exchanger to the ventilation channel of the plate-shaped dry heat exchanger and the fan at the first ventilation opening is used for exhausting the air to the outside, when the third ventilation opening is opened, part of the air entering the ventilation channel of the plate-shaped dry heat exchanger comes from the third ventilation opening, and the other part of the air comes from the plate-shaped wet heat exchanger. At this time, if the opening degree of the third air port is too large, the air duct of the plate-shaped wet heat exchanger is short-circuited.

In some embodiments, the third air outlet may be further provided with a closing door with an adjustable opening size. Wherein the closing door can be controlled to be opened by a servo motor, if the closing door adopts a sliding door, an electric cylinder can be arranged to push the sliding door, and a motor in the electric cylinder can adopt the servo motor to realize accurate control. Specifically, the opening size of the closed door can be correspondingly controlled according to the air pressure in the lower cavity, the opening degree of the closed door is correspondingly increased when the air pressure is lower, and the opening degree of the closed door is correspondingly reduced when the air pressure is higher.

In some embodiments, it is possible to have the placement in the peripheral side walls of the cavity 4: the vertical side walls transversely opposite to the upper side plate surface of the plate-shaped dry heat exchanger 2 are arranged in a closed mode, namely, the rear vertical side walls are in a closed state, so that the two dry-wet combined heat exchange devices can be arranged back to back conveniently, the space can be fully utilized, the back plates can be shared, and the cost is reduced. It is further possible to allow the upper chamber 41 to be directly ventilated to the outside only through the first ventilation openings 43 for better control of the wind direction. Of course, the rear vertical side walls of the two may be removed so as to be disposed so as to penetrate each other.

And wherein two plate-like dry heat exchangers 2 are placed in two placing cavities 4 respectively in an inclined manner and are combined into a V-shaped structure with upward openings, and at this time, the upper chambers 41 of the two placing cavities 4 are arranged in an abutting manner and can be arranged in a penetrating manner. I.e. the rear vertical side walls of the two placement cavities 4 are removed, and at this time, the two first ventilation openings 43 may be combined or spaced. In the case of the combination arrangement, one fan 5 may be provided at the first ventilation opening 43, or a plurality of fans 5 may be provided in parallel in the lateral direction. The two side walls of the two placing cavities 4 far away from each other are respectively provided with a second air vent 44 and the plate-shaped wet heat exchanger 3, and at this time, the two second air vents 44 can be both used as air inlets.
