[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0050] Embodiment 1
[0051] As Figure 1 shown, this embodiment provides a recyclable dehumidifying and ventilating device, including two dehumidifying bin bodies 1, and each dehumidifying bin body 1 can operate independently. The dehumidifying bin body 1 has an air inlet 2 and an air outlet 3. The un-dehumidified air enters the dehumidifying bin body 1 through the air inlet 2, and the dehumidified air is discharged through the air outlet 3. A liquid discharge port is further provided at the bottom of the dehumidifying bin body 1.
[0052] An intake fan 4 is provided at the intake port 2, and the intake fan 4 is used to suck natural air into the dehumidification chamber 1. In this embodiment, the intake fan 4 adopts a large-flow fan.
[0053] A molecular sieve plate 5 is provided in the dehumidification chamber 1. The molecular sieve plate 5 is provided with a pore structure, and the pore size is controllable. The molecular sieve plate 5 has good adsorption capacity, and its surface has strong surface force, which can attract and fix molecules of a specific size. Due to the different pore sizes and shapes, the molecular sieve plate 5 can selectively adsorb specific molecules. In this embodiment, by using the volume difference between water molecules and air molecules, the pore size on the molecular sieve plate 5 is smaller than the volume of water molecules, so as to realize the selective adsorption of water molecules by the molecular sieve plate 5. The utility model 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 move irregularly and collide, generating molecular condensation 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 only adsorbs water molecules on its surface. Adsorption is a physical change process and no chemical change occurs. The adsorption capacity of the molecular sieve plate 5 is limited; removing the water molecules condensed on the surface of the molecular sieve plate 5 to make the molecular sieve plate 5 have adsorption capacity again is called regeneration. To enable the molecular sieve plate 5 to have adsorption capacity 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 emissions of H2S, SO2, NOX, formaldehyde, etc. are increasing day by day. The molecular sieve plate 5 adopts 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 the control system. The control system is used to control the temperature of the heating device 6. The heating device 6 is used to quickly and evenly heat the molecular sieve plate 5 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. The moisture absorption fan 7 is installed at the top outside the dehumidification chamber 1. The moisture absorption fan 7 is used to timely extract the water vapor generated by vaporizing the water on the molecular sieve plate 5 after being heated by the heating device 6 out of the chamber, preventing the water vapor from circulating inside the dehumidification chamber 1 and hindering the reduction and regeneration of the molecular sieve plate 5. The moisture absorption fan 7 starts when the heating device 6 is turned on to timely discharge the water vapor generated by heating out of the chamber.
[0058] Due to the intervention of cold air, the water vapor that was not discharged in time condenses into water droplets and accumulates at the bottom of the dehumidification chamber body 1, and is discharged from the liquid discharge port at the bottom of the dehumidification chamber body 1.
[0059] The two dehumidification chamber bodies 1 are respectively an A chamber and a B chamber. When the molecular sieve plate 5 in the A chamber needs to be regenerated, the A chamber stops operating, undergoes regeneration and reduction, and the B chamber is started to operate to remove water molecules in the air. When the molecular sieve plate 5 in the B chamber needs to be regenerated, the B chamber stops operating, and the two chamber bodies operate alternately to provide uninterrupted dry and purified air for the room.
[0060] In this embodiment, the A chamber and the B chamber are symmetrically arranged, and the symmetrical setting can weaken the noise superposition effect and is beneficial to sound absorption.
[0061] In this embodiment, the dehumidification chamber body 1 is made of stainless steel material and is not easily rusted, corroded or deformed in a humid environment.
[0062] In this embodiment, a replacement port is further provided on the dehumidification chamber body 1 to facilitate the replacement of the molecular sieve plate 5 therein. The molecular sieve plate 5 is arranged inside the dehumidification chamber body 1, which can prevent the molecular sieve plate 5 from being polluted.
[0063] In this embodiment, the heating device 6 includes four groups of variable-frequency waterproof heating rods, which have waterproof characteristics and will not cause electric leakage to prevent accidents. The variable-frequency characteristics can better control the temperature change, 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 a better use effect, for example, controlling the heating time of the heating device 6 through the control system.
[0064] In this embodiment, a hinge door is installed on the dehumidification chamber body 1. When the hinge door is opened, it serves as the air inlet of the dehumidification chamber body 1 and has good gas conductivity, so that there is no dead angle of gas flow inside the dehumidification chamber body 1. When the hinge door is closed, the dehumidification chamber body 1 has good airtightness.
[0065] The hinge door is an electric hinge door and can be controlled electrically. The large-flow fan and the hinge door can both be connected to the control system. The control system can control the opening and closing of the large-flow fan and the hinge door. When the preset time is reached, the large-flow fan stops working and the hinge door closes to heat and regenerate the molecular sieve plate 5 to achieve the effect of repeated use.
[0066] Among them, the control system has a PLC control program and can independently control the large-flow fan, the hinge door, and the heating device 6. The electric hinge door can adopt an electric louver.
[0067] The working principle of the recyclable dehumidifying and ventilating device in this embodiment is as follows: Natural air is inhaled through a large-flow fan and enters the inside of bin A. It is filtered and purified by the molecular sieve plate 5 to remove water vapor, and the formed dry and clean air is blown into the room. After the molecular sieve plate 5 is saturated with absorption, bin A stops operating and starts the regeneration process. The heating device 6 inside the molecular sieve plate 5 heats the water adsorbed on the molecular sieve plate 5 to remove the water vapor for recycling. The internal water vapor is evacuated from the bin body by the moisture absorption fan 7. Bin B starts and repeats the operation mode of bin A to achieve alternating operation, providing uninterrupted and large-flow dry and purified air to the room.
[0068] The recyclable dehumidifying and ventilating device described in this embodiment can be applied to various industrial fields, such as the chemical industry, food processing, substations in the power system, power plants, large, medium, and small variable-frequency rooms, excitation rooms, electrical rooms, and distribution rooms dedicated to hydropower stations, etc., electrical equipment protection rooms or a series of electronic equipment fields that require dry and purified air, and the application range is very wide. For example, by using the recyclable dehumidifying and ventilating device in this embodiment to dehumidify and ventilate the busbar housing 9, it can ensure that the busbar 10 inside the busbar housing 9 is in a dry environment, reducing the risk of electrical faults such as short circuits or electric leakage. Reducing the moisture inside 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 maintaining dryness helps to maintain the good insulation performance of the busbar housing 9, ensuring that the busbar housing 9 meets the electrical safety standards. The recyclable dehumidifying and ventilating device described in this embodiment can be installed indoors or outdoors.
[0069] With the above structure, it can reduce the moisture in natural air and achieve the effect of dry air; the utility model injects clean and dry air into the room to reduce the air humidity, and can be applied in electrical rooms, equipment rooms, variable-frequency rooms, etc., which can ensure the product quality and production efficiency, reduce the number of equipment failures caused by moisture, extend the service life of mechanical equipment, avoid the corrosion or damage of electronic components, extend the service life of electronic components, ensure the smooth progress of chemical reactions, and ensure the reliability of experimental results.
[0070] Embodiment 2
[0071] The difference from Embodiment 1 of this embodiment is that when the recyclable dehumidifying and ventilating device is installed outdoors, a solid water remover 8 also needs to be installed. The solid water remover 8 adopts an S-shaped demister, and the S-shaped demister is installed at the air inlet of the recyclable dehumidifying and ventilating device, which can protect the equipment from being damaged by moisture, improve the gas quality, and ensure the stability of the process flow and the quality of the product.
[0072] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
