Description

Technical Field

[0001] The present invention relates to the technical field of air filtration and purification, and more particularly to an electronic filtration air purification system and its applications in medical and industrial sites. Background Art

[0002] With the continuous improvement of people's requirements for air quality, electronic filtration air purification systems are increasingly widely used in medical and industrial sites. Traditional air purification systems mainly rely on mechanical filtration and chemical adsorption, but these methods have problems such as low efficiency, high energy consumption, and high maintenance costs when dealing with fine particulate matter and harmful gases. In recent years, electronic filtration technology has gradually become a research hotspot in the field of air purification due to its advantages of high efficiency, low energy consumption, and low maintenance costs.

[0003] Electronic filtration technology realizes air purification through two core links: ionization and dust collection. In the ionization zone, corona discharge is generated using high voltage to charge the particulate matter in the air; in the dust collection zone, the charged particulate matter is adsorbed onto the dust collection plate through an electric field.

[0004] However, wind speed is an important factor affecting the electronic filtration effect. Research shows that the lower the wind speed, the higher the filtration efficiency, because at low wind speeds, particulate matter stays in the filter material for a longer time and has more opportunities to collide with obstacles. However, most existing electronic filtration systems do not precisely control the wind speed, resulting in limited purification effects. In addition, too high a wind speed will increase the resistance of the filter and shorten its service life.

[0005] In view of the deficiencies of existing electronic filtration air purification systems in terms of purification effect and wind speed control, it is particularly necessary to develop an electronic filtration air purification system that can precisely control the wind speed. This improved technology will provide a higher-quality air purification solution for medical and industrial sites and meet the strict requirements for air quality. Summary of the Invention

[0006] In view of this, the present invention provides an electronic filtration air purification system and its applications in medical and industrial sites. By adding a wind speed control structure before electronic filtration, the air flow rate can be optimized, the purification efficiency can be improved, and the energy consumption and maintenance costs can be reduced at the same time.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] An electronic filtration air purification system includes an air purification circulation pipeline. The inlet of the air purification circulation pipeline introduces the air to be purified and treated through a blower fan and discharges it from the outlet at the other end. It also includes the following components arranged in sequence from the inlet to the outlet of the air purification circulation pipeline:

[0009] Primary filter, air velocity control mechanism, ionization zone, dust collection zone, sterilization and disinfection zone, and air outlet;

[0010] Air first passes through the primary filter to preliminarily remove large particulate dust and impurities. Subsequently, the air enters the air velocity control mechanism, which adjusts the air velocity according to preset air velocity parameters to bring the air velocity within the range required for the best purification effect. The adjusted air then enters the ionization zone, where the ionization effect causes the particulate matter in the air to carry charges. The charged particulate matter then enters the dust collection zone, which uses an electric field to adsorb the charged particulate matter to achieve air purification. The purified air enters the sterilization and disinfection zone, where the air is sterilized and disinfected. Finally, the air that has been purified and sterilized is discharged from the air outlet.

[0011] Through the above technical solution, the present invention realizes the full-process optimization from preliminary filtration to final purification by sequentially arranging a primary filter, an air velocity control mechanism, an ionization zone, a dust collection zone, a sterilization and disinfection zone, and an air outlet in the air purification circulation pipeline. This structural design can effectively remove large particulate dust, fine particulate matter, and harmful gases in the air and perform sterilization and disinfection treatment, significantly improving the air purification efficiency and quality.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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] See attached Figure 1 The embodiment of the present invention discloses an electronic filtration air purification system, comprising an air purification circulation pipeline 1, the inlet of the air purification circulation pipeline 1 introduces air to be purified through an induced draft fan and discharges it from the outlet at the other end; and further comprising the following arranged in sequence from the inlet to the outlet of the air purification circulation pipeline 1:

[0051] Primary filter 2, wind speed control mechanism 3, ionization area 4, dust collection area 5, sterilization and disinfection area 6 and air outlet 7;

[0052] The air first passes through the primary filter 2 to preliminarily remove large particles of dust and impurities; then, the air enters the wind speed control mechanism 3, which controls the air flow rate according to the preset wind speed parameters to make the air flow rate reach the range required for the best purification effect; the regulated air enters the ionization zone 4, and the ionization zone 4 charges the particles in the air through ionization; the charged particles then enter the dust collection zone 5, and the dust collection zone 5 uses the electric field to adsorb the charged particles to purify the air; the purified air enters the sterilization and disinfection zone 6, and the sterilization and disinfection zone 6 sterilizes and disinfects the air; finally, the purified and sterilized air is discharged from the air outlet 7.

[0053] See attached Figure 2, the wind speed regulation mechanism 3 includes two diversion wind plates 31 that are relatively slidably connected within the air purification and circulation pipeline 1. The two diversion wind plates 31 are provided with diversion air vents 311 corresponding in position. Such that when the distance between the two diversion wind plates 31 is closer, the diversion air vents 311 on the two diversion wind plates 31 are closer, and the diversion wind speed is faster; when the distance between the two diversion wind plates 31 is farther, the diversion air vents 311 on the two diversion wind plates 31 are farther apart, and the diversion wind speed is slower.

[0054] The wind speed regulation mechanism 3 realizes precise regulation of the wind speed through the two relatively slidable diversion wind plates 31 and the diversion air vents 311 thereon. When the distance between the two diversion wind plates is closer, the diversion wind speed is faster; when the distance is farther, the diversion wind speed is slower. This design can flexibly adjust the wind speed according to different purification requirements, ensuring that the air stays in the ionization area and the dust collection area for a long enough time, thereby improving the purification efficiency. The structural design of the diversion wind plates 31 and the diversion air vents 311 can also effectively control the air flow rate during the diversion process.

[0055] To further optimize the above technical solution, the wind speed regulation mechanism 3 further includes guide rods 32, a driving screw 33, threaded blocks 34, a driven gear 35, a driving gear 36, and a handwheel 37; the number of guide rods 32 is multiple, and they are installed on the inner wall of the air purification and circulation pipeline 1, and the diversion wind plates 31 are slidably connected to the guide rods 32; both ends of the driving screw 33 are rotatably connected to the bottom inner wall of the air purification and circulation pipeline 1, and the driving screw 33 has threads in opposite directions; the number of threaded blocks 34 is two, and they are respectively connected to the threads in opposite directions on the driving screw 33, and the two threaded blocks 34 are respectively fixed to the two diversion wind plates 31. The driven gear 35 is fixed to one end of the driving screw 33, the driving gear 36 is rotatably connected to the bottom inner wall of the air purification and circulation pipeline 1, and meshes with the driven gear 35. The central axis of the driving gear 36 passes through the outside of the air purification and circulation pipeline 1 and is fixed to the handwheel 37.

[0056] Through the mechanical transmission structure composed of the guide rods 32, the driving screw 33, the threaded blocks 34, the driven gear 35, the driving gear 36, and the handwheel 37, precise control of the position of the diversion wind plates 31 is achieved. This structural design not only improves the flexibility and precision of wind speed regulation but also facilitates operation and maintenance. The detailed design of the mechanical transmission structure ensures the smooth movement and precise regulation of the diversion wind plates 31.

[0057] To further optimize the above technical solution, a wind speed sensor 8 is provided at the rear outlet of the wind speed regulation mechanism 3.

[0058] A wind speed sensor 8 is provided at the rear outlet of the wind speed regulation mechanism 3, which can monitor the air flow velocity after regulation in real time. Through the feedback mechanism, the wind speed regulation effect can be further optimized to ensure that the system always operates in the best purification state. The position of the wind speed sensor 8 is reasonably set, which can effectively monitor the air flow velocity.

[0059] See Appendix Figure 3 The ionization zone 4 includes a plurality of ionization wires or ionization needles 41, and the ionization wires or ionization needles 41 are connected to a high-voltage power supply to generate corona discharge, making the particulate matter in the air carry negative charges.

[0060] This design can efficiently ionize the particulate matter in the air, improve the charging rate of the particulate matter, and thus enhance the adsorption effect in the subsequent dust collection zone. The layout of the ionization wires or ionization needles 41 is reasonable, which can effectively generate corona discharge.

[0061] The dust collection zone 5 includes multiple groups of parallel dust collection plates 51, and the dust collection plates 51 are grounded for adsorbing charged particulate matter.

[0062] This structural design not only improves the dust collection efficiency but also facilitates the cleaning and maintenance of the dust collection plates. The parallel layout of the dust collection plates 51 can effectively adsorb charged particulate matter. In this embodiment, the dust collection plates 51 are all designed to be detachable from the side wall of the air purification circulation pipeline 1 for easy replacement and cleaning.

[0063] See Appendix Figure 4 The sterilization and disinfection zone 6 includes a support plate 61, a transparent air duct 62, and an ultraviolet lamp 63; the number of support plates 61 is two, and they are fixedly spaced inside the air purification circulation pipeline 1, and diversion air vents 611 are provided on the support plate 61; the number of transparent air ducts 62 is multiple, and they are fixedly connected between the two support plates 61 and correspond to the diversion air vents 611 on the two support plates 61; the ultraviolet lamp 63 is arranged between the two support plates 61 and is located between the multiple transparent air ducts 62.

[0064] The sterilization and disinfection zone adopts the combined design of the support plate 61, the transparent air duct 62, and the ultraviolet lamp 63, which can effectively sterilize and disinfect the purified air. The design of the transparent air duct 62 ensures the uniform irradiation of ultraviolet rays and improves the sterilization effect. The structural design of the sterilization and disinfection zone is reasonable, which can effectively achieve the sterilization and disinfection function.

[0065] To further optimize the above technical solution, both ends of the transparent air duct 62 form a flared structure 621.

[0066] The flared structures 621 at both ends of the transparent air duct 62 can effectively guide the air flow, reduce the air resistance, and improve the air circulation efficiency. This design not only optimizes the air flow path but also further improves the working efficiency of the sterilization and disinfection zone.

[0067] See the appendix Figure 5 Figure 5 At the inlet of the air purification circulation pipeline 1, there is also a fresh air introduction pipeline 9, and a control valve 91 is provided on the fresh air introduction pipeline 9 to realize the switching between the internal circulation and the external circulation.

[0068] Setting a fresh air introduction pipeline 9 at the inlet of the air purification circulation pipeline and equipping it with a control valve 91 can realize the switching between the internal circulation and the external circulation. This design not only meets the ventilation requirements of different places, but also improves the flexibility and applicability of the system.

[0069] The electronic filtration air purification system of the present invention significantly improves the air purification efficiency and quality through precise air velocity regulation, efficient ionization and dust collection design, advanced sterilization and disinfection functions, and flexible internal and external circulation switching. Such a system is not only applicable to medical and industrial places, but also can meet other scenarios with strict air quality requirements. By optimizing the air velocity and multi-stage purification treatment, the system can effectively remove particulate matter and harmful gases in the air, while reducing energy consumption and maintenance costs, and has remarkable innovation and practicality.

[0070] Example 1:

[0071] In medical places, such as hospital operating rooms and ICU wards, the air quality requirements are extremely high, and it is necessary to ensure the sterility of the air and a low particulate matter concentration.

[0072] Operating room:

[0073] Air velocity control condition: The air velocity should be controlled at a relatively low level (such as 0.3 - 0.5 m / s) to ensure that the air has sufficient residence time in the ionization area and the dust collection area, so as to efficiently remove viruses, bacteria and fine particles in the air.

[0074] Reason: The low air velocity can extend the residence time of particulate matter in the electric field, improve the charging rate and adsorption efficiency, so as to ensure the sterility of the operating environment.

[0075] ICU ward:

[0076] Air velocity control condition: The air velocity should be controlled at 0.4 - 0.6 m / s to balance the purification efficiency and the air circulation speed.

[0077] Reason: The ICU ward requires continuous air circulation, but at the same time, it is necessary to ensure that the pollutants in the air are effectively removed. The low air velocity can improve the purification efficiency and avoid the re-suspension of particulate matter caused by too high air velocity.

[0078] Example 2:

[0079] Industrial places

[0080] In industrial settings, such as electronic manufacturing workshops and chemical production workshops, strict air quality requirements necessitate the efficient removal of particulate matter and harmful gases from the air.

[0084] Chemical production workshop:

[0085] Wind speed control condition: The wind speed should be controlled between 0.6 - 0.8 m / s to ensure the effective removal of harmful gases and particulate matter in the air.

[0086] Reason: There may be various harmful gases and particulate matter in chemical production workshops. Higher wind speed can increase the air circulation speed, ensuring the timely purification of harmful substances while avoiding increased energy consumption due to excessive wind speed.

[0095] Example 4:

[0096] In home and office environments, air quality directly affects the health and comfort of occupants.

[0097] Home environment:

[0106] Wind speed control condition:

[0107] Wind speed range: 1.0 - 1.5 m / s;

[0108] Reason: High wind speed can quickly carry the paint mist and harmful gases away from the working area, reducing the exposure time of workers and ensuring the air quality in the spraying workshop.
