Description

Technical Field

[0001] This invention relates to a water curtain layered air purification and disinfection machine. Background Technology

[0002] Currently, water curtain air purification and disinfection is one type of air purification and disinfection product on the market. It is popular due to its advantages of high efficiency, non-toxicity, low operating cost, and no solid hazardous waste. However, water curtain air filters are limited by the pressure per unit cross-section of the water curtain, which restricts the overall ventilation volume of the machine. In other words, a single water curtain cannot support a large air volume operation. Therefore, the resulting water curtain air purifiers can only be used in small spaces, and their use in large public spaces is limited. Therefore, the inventors designed a multi-layered water curtain air purifier that fully utilizes the machine's longitudinal (vertical) physical space to produce a large ventilation volume, thereby meeting the air purification and disinfection needs of large spaces. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems existing in the air disinfection and purification technologies of the prior art. This invention provides a multi-layered air purification and disinfection machine. This invention designs a multi-layered air purification and disinfection machine, including a body, a fan, a water tank, and a controller. Its features include: a water tank at the bottom of the body; front and rear chambers at the top of the body, separated by a partition plate; a control room at the top of the front chamber, housing a power supply, a controller, and a high-voltage electrostatic generator; and several vertically arranged water curtain tanks installed on the front side of the front chamber, wherein each water curtain tank is elongated and parallel to the width of the body, and a passage perpendicular to the axial direction of each water curtain tank is located below it. The ventilation space is formed by the front wall of the main body and a partition plate at the rear. Air inlets and outlets are located at corresponding positions on the front wall and partition plate, respectively. A high-voltage discharge wire is installed inside the air inlet on the front wall of the main body, connecting to the output of a high-voltage electrostatic generator. Each water curtain tank has a water curtain nozzle at its bottom, equipped with an electrode plate connected to the other output of the high-voltage electrostatic generator. Each water curtain tank is connected to a water pump via a water pipe. A water receiving trough is located at the bottom of the ventilation space below each water curtain tank. A fan is installed at the top of the rear cavity of the main body. The water curtain nozzles are parallel to the axial direction of the water curtain tank. The water receiving trough is connected to the tank via a water receiving pipe. The water pump is a submersible pump placed inside the tank. The water receiving pipe for the water receiving trough is a fabric water pipe. The water curtain nozzle at the bottom of the lowest water curtain tank faces the water surface directly. Each water curtain tank is connected to a water pump via a water pipe. All water curtain tanks are connected to a water pump via water pipes and flow valves. The advantage of this invention is that it solves the challenge of purifying and disinfecting large volumes of air with a relatively small machine size. Attached Figure Description

[0009] The present invention will now be described in detail with reference to the embodiments and accompanying drawings: Figure 1-5 A multi-layered air purification and disinfection machine includes a body 1, a fan 2, a water tank 3, and a controller 4. Its features include: a water tank at the bottom of the body; front and rear chambers at the top of the body, separated by a partition plate 5; a control room 6 at the top of the front chamber, housing a power supply 7, the controller 4, and a high-voltage electrostatic generator 8; and several vertically arranged water curtain receiving trays 9 mounted on the front side of the front chamber, each tray being elongated and parallel to the width of the body. Each water curtain receiving tray has a front and rear ventilation space 10 below it. The unit has a front wall at one end and a water / air separation plate at the other end. Air inlets 11 and outlets 12 are located on the front wall and the separation plate, respectively. A high-voltage discharge line 13 is installed inside the air inlet on the front wall of the unit at the front end of the ventilation space. The high-voltage discharge line is connected to the output end of a high-voltage electrostatic generator. Each water curtain tank has a water curtain nozzle 14 at its bottom, and an electrode plate 15 is installed at the nozzle, connected to the other output end of the high-voltage electrostatic generator. Each water curtain tank is connected to a water pump 16 by a water pipe 19. A water receiving trough 17 is installed at the bottom of the ventilation space below each water curtain tank. A fan is installed at the top of the rear cavity of the upper part of the unit. The water curtain nozzles are parallel to the axial direction of the water curtain tank. The water receiving trough is connected to the water tank by a water receiving pipe 18. The water pump is a submersible pump placed inside the water tank. The water receiving pipe of the water receiving trough is a fabric water pipe. Each water curtain tank is connected to a water pump by a water pipe. All water curtain tanks are connected to a (large) water pump via water pipes and flow valves.

[0010] Figure 3 In the middle section, the water curtain spray nozzles at the bottom of the lowest water curtain tank face the water surface 21 directly, which can eliminate the need for the bottom water receiving tank. The top of the water tank is open, and the falling water curtain directly faces the water surface of the tank, which will produce a large water flow sound. It can be used in places where silence is not required.

[0011] To enable operation in areas with poor environmental conditions, a coarse filter can be installed at the air inlet of the unit. This filter can use fine steel wire or nylon mesh to remove long fibers, hair, and coarse particles from the air, preventing the water curtain nozzles and water pump from becoming clogged.

[0012] Each water curtain tank is constructed using water pipes (installed along the edge). Figure 2 , 3 (The diagram shows a connection.) Each water curtain is connected to a water pump to achieve the effect of not interfering with each other.

[0013] To reduce noise, two or more fans can be used while still meeting the required air volume.

[0014] After placing the invention indoors and turning it on, the water pump operates, pumping water from the water tank into the water curtain tank, and spraying it out from the water curtain nozzles to form a water curtain 20. The water curtain falls into the water receiving trough below (a buffer block made of synthetic fiber can be placed in the water receiving trough to reduce the water flow noise generated by the water curtain impacting the water receiving trough), and flows into the water tank through the water receiving pipe (using a fabric water pipe as the water receiving pipe is also to reduce noise, because the fabric water pipe expands or contracts according to the size of the water flow, which can reduce the water flow noise generated by the falling water impacting the water surface of the water tank; the water receiving pipe is installed close to the edge). Figure 2 , 3 (The diagram shows a connection schematic). When air is drawn into the front of the unit by the fan, it first passes through a high-voltage discharge line (fixed on a frame parallel to the air inlet). Since the water curtain is connected to the other output of the high-voltage electrostatic generator via an electrode plate, a high-voltage electrostatic field is formed between the high-voltage discharge line and the water curtain. When air passes through, the substances in the air are ionized, forming charged particles. Upon encountering the water curtain (which forms one electrode of the high-voltage electrostatic field), these particles are attracted by the water curtain (opposites attract). Due to the surface tension of water, substances such as bacteria, viruses, and particulate dust that have entered the water cannot escape. The layered water curtain structure invented in this invention solves the problem of high-volume purification and disinfection in a limited space within the disinfection chamber.
