[0001] This utility model relates to the technical field of central air conditioning air purification and disinfection equipment, specifically a central air conditioning air purification and disinfection equipment. Background Technology

[0002] Central air conditioning refers to a large-scale air conditioning system, which consists of a main unit and terminal units. The main unit is divided into water-cooled units and air-cooled units, while the terminal equipment mainly consists of air conditioning units and fan coil units. Central air conditioning is different from ordinary household air conditioning and can be used in large-scale buildings.

[0003] Currently, in existing technologies, filters are usually installed at the fan coil unit ports of central air conditioning systems to filter dust in the air. However, simply using filters to filter dust cannot achieve the effect of purifying the air. In actual use scenarios, fan coil units extend into multiple rooms, each with a different air environment, which may cause cross-infection between different rooms. Therefore, it is necessary to propose a central air conditioning purification and disinfection device. Utility Model Content

[0013] Preferably, a first filter plate is inserted into one end of the filter chamber near the ionization chamber, and a second filter plate is inserted into the other end of the filter chamber.

[0014] The advantages of this utility model are:

[0015] This invention applies a high-voltage positive charge to the ionization plate, causing corona discharge in the air passing through the ionization chamber.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an air purification and disinfection device for central air conditioning systems. (Refer to...) Figures 1-5 A central air conditioning air purification and disinfection device includes an air inlet pipe 1, an ionization chamber 2 fixedly connected to one end of the air inlet pipe 1, the ionization chamber 2 having a semi-circular horizontal cross-section, an ionization plate 21 inserted into the bottom of the ionization chamber 2, an air purification mechanism 3 fixedly connected to one end of the ionization chamber 2, and an air outlet pipe 4 fixedly connected to the other end of the air purification mechanism 3. By introducing air through the air inlet pipe 1, a high-voltage positive charge is applied to the ionization plate 21 inside the ionization chamber 2, causing corona discharge in the air passing through the ionization chamber 2. This positively charges dust, microorganisms, and some aerosols in the air. The semi-circular shape of the ionization chamber 2 extends the airflow path, thereby increasing the probability of charged particles and microorganisms in the air. Simultaneously, an ionization plate 21 is applied within the air purification mechanism 3. By increasing the negative voltage, a strong electric field opposite to that of the ionization chamber 2 is formed. Charged particles, dust, and microorganisms in the air after passing through the ionization chamber 2 are adsorbed into the air purification mechanism 3 under the action of Coulomb force. The purified air flows out through the air outlet pipe 4, thereby achieving the effect of purifying the air. The purification and disinfection principle adopted in this embodiment is the high-voltage electrostatic disinfection principle. Its basic principle is based on the fact that the high-voltage electric field causes the cell membrane of microorganisms to be electrically broken down under the action of the strong electric field, producing irreparable perforations or ruptures, thereby causing damage to cell tissue and inactivating microorganisms, thereby achieving the purpose of disinfection. In specific implementation, the electrostatic disinfection controller is integrated into the controller of the central air conditioning system, so that air purification and disinfection can be performed through the controller of the central air conditioning system.

[0026] The air purification mechanism 3 includes a filter chamber 31, an adsorption chamber 33 is inserted into the inner cavity of the filter chamber 31, the adsorption chamber 33 is attached to the inner wall of the filter chamber 31, a dust collection rack 35 is fixedly connected to the inner cavity of the adsorption chamber 33, a dust collection plate 36 is fixedly connected to the inner cavity of the dust collection rack 35, and a gap is provided between the dust collection racks 35. The surface of the dust collection plate 36 is provided with honeycomb holes 37, and a collection chamber 38 is provided at the bottom of the inner cavity of the adsorption chamber 33. The collection chamber 38 is connected to the inner cavity of the adsorption chamber 33. By applying a high voltage negative charge to the dust collection plate 36, particles and microorganisms in the air become positively charged after passing through the ionization chamber 2. When they pass through the adsorption chamber 33, the dust collection rack 35 supports the dust collection plate 36 and uses electrostatic adsorption to adsorb particles and microorganisms in the air. The honeycomb holes 37 on the dust collection plate 36 accelerate the adsorption efficiency, and the collection chamber 38 collects the dust on the dust collection plate 36.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The bottom of the ionization chamber 2 is provided with a first slot 23, and the ionization plate 21 is inserted into the first slot 23. The ionization plate 21 is attached to the inner wall of the ionization chamber 2. There are three ionization plates 21. The inner wall of the ionization plate 21 is continuously provided with ionization wires 22, and there are gaps between the ionization wires 22. The ionization plate 21 is stably inserted into the ionization chamber 2 through the first slot 23. All three ionization plates 21 apply high voltage positive electricity to the air through the ionization wires 22.

[0028] Reference Figure 3 and Figure 4 The filter chamber 31 is fixedly connected to one end of the ionization chamber 2. The vertical cross-section of the inner cavity of the filter chamber 31 is V-shaped. A second slot 32 is provided at the bottom of the filter chamber 31. The adsorption chamber 33 is inserted into the second slot 32. A fixing frame 34 is fixedly connected to the outer wall of the adsorption chamber 33. The fixing frame 34 is fixedly connected to the bottom of the filter chamber 31. A dust removal pipe 39 is fixedly connected to the bottom of the collection chamber 38. A vacuum cleaner 310 is fixedly connected to one end of the dust removal pipe 39. A first filter plate 311 is inserted into the end of the filter chamber 31 near the ionization chamber 2. A second filter plate 312 is inserted into the other end of the filter chamber 31. Through the particles and When microorganisms and other microorganisms pass through the V-shaped filter chamber 31, the particles and microorganisms first dive downwards towards the dust collection plate 36, and then are adsorbed after impacting the dust collection plate 36 under the action of inertia. Then the purified air is blown upwards from the filter chamber 31, thereby improving the adsorption efficiency of the dust collection plate 36. The fixing frame 34 supports the adsorption chamber 33 to be stably inserted into the second slot 32. The collection chamber 38 at the bottom of the adsorption chamber 33 works with the dust removal pipe 39 and the vacuum cleaner 310 to clean the dust adsorbed on the dust collection plate 36. The first filter plate 311 and the second filter plate 312 work together to filter larger impurities in the air.

[0029] Working principle: In use, the air intake pipe 1 is connected to the end of the central air conditioning coil. First, a high-voltage positive charge is applied to the ionization wire 22, and a high-voltage negative charge is applied to the dust collection plate 36. Air is introduced into the ionization chamber 2 through the air intake pipe 1. As the air passes through the ionization chamber 2, the ionization plate 21 inserted in the first slot 23 applies a high-voltage positive charge to particles and microorganisms in the air. Then, the air passes through the filter chamber 31 of the air purification mechanism 3 for purification and disinfection. The fixing frame 34 stably supports the adsorption chamber 33 inserted in the second slot 32. As the air passes through the adsorption chamber 33, the dust collection frame... The dust collection plate 36 on 35 uses Coulomb force to adsorb impurities such as particles and microorganisms in the air. The honeycomb holes 37 on the dust collection plate 36 accelerate the adsorption efficiency of the dust collection plate 36. The first filter plate 311 and the second filter plate 312 work together to filter larger impurities in the air. Then, the purified and disinfected air is discharged through the air outlet pipe 4, thereby achieving the purpose of air purification and disinfection. When the adsorption chamber 33 is cleaned, the vacuum cleaner 310 is used to extract the impurities adsorbed and retained on the dust collection plate 36. The impurities are discharged through the collection chamber 38, the cleaning pipe 39 and the vacuum cleaner 310.
