[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Example 1

[0051] like Figure 1 As shown, this embodiment provides a cyclic dehumidification and ventilation device, including two dehumidification chambers 1, each of which can operate independently. The dehumidification chamber 1 has an air inlet 2 and an air outlet 3. Undehumidified air enters the dehumidification chamber 1 from the air inlet 2, and the dehumidified air is discharged through the air outlet 3. A drain port is also provided at the bottom of the dehumidification chamber 1.

[0052] An air intake fan 4 is provided at the air inlet 2, and the air intake fan 4 is used to draw natural air into the dehumidification chamber 1. In this embodiment, the air intake fan 4 is a large-flow fan.

[0053] The dehumidification chamber body 1 is provided with a molecular sieve plate 5, and a pore structure is provided on the molecular sieve plate 5, and the pore size is controllable. The molecular sieve plate 5 has good adsorption capacity, and its surface has a strong surface force, which can attract and fix molecules of a specific size. Due to the difference in pore size and shape, the molecular sieve plate 5 can selectively adsorb specific molecules. In this embodiment, the pore size on the molecular sieve plate 5 is smaller than the volume of water molecules by utilizing the volume difference between water molecules and air molecules, so that the molecular sieve plate 5 can selectively adsorb water molecules. The present invention realizes the selective adsorption of water molecules through the pore structure and surface force of the molecular sieve plate 5. The water molecules in the air make irregular movements and collide, and molecular condensation occurs on the surface of the molecular sieve plate 5, so as to achieve the purpose of separating and removing water molecules in the air.

[0054] The molecular sieve plate 5 merely adsorbs water molecules on the surface. Adsorption is a physical change process without chemical changes. The adsorption capacity of the molecular sieve plate 5 is limited. The process of removing the water molecules condensed on the surface of the molecular sieve plate 5 so that the molecular sieve plate 5 regains adsorption capacity is called regeneration. In order to achieve the adsorption capacity of the molecular sieve plate 5 again, a heating device 6 is provided inside the molecular sieve plate 5. The heating device 6 vaporizes the water on the molecular sieve plate 5, thereby removing the water molecules condensed on the surface of the molecular sieve plate 5, and achieving the effect of recycling the molecular sieve plate 5.

[0055] With the rapid development of industry, the emission of H2S, SO2, NOX and formaldehyde is increasing day by day. The molecular sieve plate 5 is an air purification adsorption sieve plate, and its purification characteristics can also purify pollutants in the air.

[0056] The heating device 6 is connected to a control system, and the control system is used to control the temperature of the heating device 6. The heating device 6 is used to heat the molecular sieve plate 5 quickly and evenly to prevent the molecular sieve plate 5 from cracking or powdering due to uneven heating.

[0057] Furthermore, a moisture absorption fan 7 is provided above the molecular sieve plate 5, and the moisture absorption fan 7 is installed on the top of the outside of the dehumidification bin body 1. The moisture absorption fan 7 is used to timely extract the water vapor generated by the vaporization of the water on the molecular sieve plate 5 after the heating of the heating device 6 out of the bin, so as to prevent the water vapor from circulating inside the dehumidification bin body 1 and hindering the reduction and regeneration of the molecular sieve plate 5. The moisture absorption fan 7 is started when the heating device 6 is turned on to discharge the water vapor generated by the heating out of the bin in time.

[0058] Due to the intervention of cold air, the water vapor that is not discharged in time condenses into water droplets when it encounters cold and gathers at the bottom of the dehumidification bin body 1, and is discharged from the drain port at the bottom of the dehumidification bin body 1.

[0059] The two dehumidification bins 1 are bin A and bin B respectively. When the molecular sieve plate 5 in bin A needs to be regenerated, bin A is stopped for regeneration and restoration, and bin B is started to operate to remove water molecules from the air. When the molecular sieve plate 5 in bin B needs to be regenerated, bin B is stopped. The two bins operate alternately to provide uninterrupted dry and purified air to the room.

[0060] In this embodiment, the A bin and the B bin are arranged symmetrically, and the symmetrical arrangement can weaken the noise superposition effect and is conducive to noise reduction.

[0061] In this embodiment, the dehumidification bin body 1 is made of stainless steel, which is not easy to rust, corrode or deform in humid conditions.

[0062] In this embodiment, the dehumidification chamber body 1 is also provided with a replacement port to facilitate replacement of the molecular sieve plate 5 therein. The molecular sieve plate 5 is arranged inside the dehumidification chamber body 1 to prevent the molecular sieve plate 5 from being contaminated.

[0063] In this embodiment, the heating device 6 includes four groups of variable frequency waterproof heating rods, which have waterproof properties and will not leak electricity to prevent accidents. The variable frequency characteristics can better control temperature changes, so that the molecular sieve plate 5 will not crack and powder due to the rapid increase in temperature. Adding a time control mode can achieve better use effects, for example, controlling the heating time of the heating device 6 through the control system.

[0064] In this embodiment, a hinged door is installed on the dehumidification bin body 1. When the hinged door is opened, it serves as the air inlet of the dehumidification bin body 1 and has good gas conductivity, so that there is no dead corner of gas flow inside the dehumidification bin body 1. When the hinged door is closed, the dehumidification bin body 1 has good air tightness.

[0065] The folding door is an electric folding door and can be electrically controlled. Both the high-flow fan and the folding door can be connected to the control system, and the control system can control the opening and closing of the high-flow fan and the folding door. When the preset time is reached, the high-flow fan stops working, the folding door is closed, and the molecular sieve plate 5 is heated and regenerated to achieve the effect of repeated use.

[0066] The control system has a PLC control program, which can independently control the large-flow fan, the folding door, and the heating device 6. The electric folding door can be an electric shutter.

[0067] The working principle of the cyclic dehumidification and ventilation device of this embodiment is: natural air is sucked in through a large flow fan, enters the interior of warehouse A, is filtered and purified by the molecular sieve plate 5, removes water vapor and forms dry and clean wind to blow into the room, after the molecular sieve plate 5 is fully absorbed, warehouse A stops operating and starts to regenerate and restore, the moisture adsorbed on the molecular sieve plate 5 is heated by the heating device 6 inside the molecular sieve plate 5, the water vapor is removed and regenerated and reused, and the internal water vapor is extracted from the warehouse body by the moisture absorption fan 7. Warehouse B starts, and the operation mode of warehouse A is repeated to achieve alternating operation, providing uninterrupted, large-flow dry and purified air to the room.

[0068] The cyclic dehumidification and ventilation device described in this embodiment can be applied to various industrial fields, such as chemical industry, food processing, substations of power systems, power plants, large, medium and small frequency conversion rooms, excitation rooms, electrical rooms, distribution rooms and other electrical equipment protection rooms dedicated to hydropower stations, or a series of electronic equipment fields that require dry and purified air. The application range is very wide. For example, the busbar housing 9 is dehumidified and ventilated by the cyclic dehumidification and ventilation device of this embodiment to ensure that the busbar 10 in the busbar housing 9 is in a dry environment, reducing the risk of electrical failures such as short circuits or leakage. Reducing the moisture in the busbar housing 9 can reduce the risk of metal corrosion, extend the service life of the busbar housing 9 and the busbar 10, and keep it dry to help maintain the good insulation performance of the busbar housing 9 and ensure that the busbar housing 9 meets electrical safety standards. The cyclic dehumidification and ventilation device described in this embodiment can be installed indoors or outdoors.

[0069] By adopting the above structure, it is possible to reduce the moisture in natural air and achieve the effect of drying the air; the present invention injects clean and dry wind into the room to reduce the air humidity, and can be applied to electrical rooms, equipment rooms, frequency conversion rooms, etc., to ensure product quality and production efficiency, reduce the number of equipment failures caused by moisture, extend the service life of mechanical equipment, avoid corrosion or damage to electronic components, extend the service life of electronic components, ensure the smooth progress of chemical reactions, and ensure the reliability of experimental results.

[0070] Example 2

[0071] The difference of this embodiment 1 is that when the recyclable dehumidification and ventilation device is installed outdoors, a solid dehumidifier 8 needs to be installed. The solid dehumidifier 8 adopts an S-type demister. The S-type demister is installed at the air inlet of the recyclable dehumidification and ventilation device, which can protect the equipment from damage by moisture, improve the gas quality, and ensure the stability of the process and the quality of the product.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
