Problems solved by technology

This type of treatment has shortcomings: on the one hand, it cannot remove particulate matter in the air; on the other hand, it is harmful to human health and cannot be used where there are people.
At present, particulate matter filters (HEPA) are widely used to filter indoor air microbial aerosols. This method has high efficiency in removing particulate matter, but the collected microorganisms are not killed.

Embodiment 1

[0040] Example 1 Student Dormitory Air Purification

[0041] Used in student dormitories such as Figure 6 In the air purification device shown, the student dormitory area is small, the personnel are dense and the residence time is long, and the microbial pollution is relatively serious. In this embodiment, the line-board discharge module 5 with quieter discharge and lower ozone production is installed into the inner space of the air purification device In the middle of 1, its anode guide rod 503 and cathode guide rod 504 are respectively connected to the circuit control box 4 by wires, and the discharge voltage is controlled by the circuit control box 4 to be 6kV; there is a negative pressure fan on the top of the inner space 1, and the same fan is connected to the The circuit control box 4, the fan speed is controlled by the circuit control box 4, so that the processing gas volume is 10,000h -1 Install the HEPA filter 9 at the bottom of the internal space 1, and install an ...

example 2

[0042] Example 2 Air purification of underground parking lot

[0043] Used in underground car parks such as Figure 7 In the air purification system shown, the underground parking lot has a large area, less personnel activities and shorter time, less demand for particle pollution treatment and more serious volatile organic compound pollution. This embodiment adopts a line-tube with a longer residence time and easier cleaning The discharge module 7 is installed in the middle of the inner space 1 of the air purification device, and its anode guide rod 703 and cathode guide rod 704 are respectively connected to the circuit control box 4 by wires, and the discharge voltage is controlled by the circuit control box 4 to be 10kV; the top of the inner space 1 has a Negative pressure fan, the same fan is connected to the circuit control box 4 with wires, and the circuit control box controls 4 to control the fan speed, so that the processing gas volume is 100,000h -1 Ozone catalyst 10 ...

Embodiment 3

[0044] Embodiment 3 Pig house air purification

[0045] Used in indoor closed pig houses such as Figure 8 In the air purification system shown, the indoor area of ​​the pig house is moderate, the density of pigs is relatively high, and the microbial pollution, particle pollution and odorous gas pollution bacteria are relatively serious. In this embodiment, the needle-hole plate discharge module 8 with the largest discharge intensity is installed in the air. In the center of the inner space 1 of the purification device, place the purification system as a whole horizontally, and install it through the window 11 of the pig house. The air inlet 2 is placed in the pig house room, and the air outlet 3 is placed outdoors. In this way, the purification system replaces the ventilation fan At the same time, the air in the pig house can be purified and discharged. The anode guide rod 803 and the cathode guide rod 804 of the needle-orifice discharge module 8 are respectively connected t...

Abstract

The invention discloses a method and a device for eliminating microbial aerosol in indoor air by using corona discharge. The method, on one hand, inactivates microorganism at room temperature by using low-temperature plasma motivated by corona discharge, on the other hand, separates microbial aerosol in the air by utilizing the high-voltage electric field acting force, which induces the corona to discharge, and the microbial aerosol is deposited on the earth electrode of the discharging corona by the acting force. According to the deposition of microbial aerosol, the corona discharge module is fetched out at intervals to have a cleaning. After being cleaned, the corona discharge module is put back into the processing system to eliminate microbial aerosol. The two processes are operated alternatively, thus longtime efficient operation of processing system is realized. The method and the device for eliminating microbial aerosol in indoor air by using corona discharge have the advantages of efficiency, energy saving and no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of public health and environmental protection, and relates to a purification treatment method and device for microbial aerosol in indoor air. Background technique [0002] Microbial aerosol is one of the main pollutants in indoor air, and it has the characteristics of particulate matter and microbial pollution. When the human body inhales or contacts these microbial aerosols, it may be infected with corresponding diseases (pathogenic microorganisms) or allergic reactions (fungal allergens, etc.). The Severe Acute Respiratory Syndrome (SARS) outbreak in 2003 and the avian influenza (H1N1 infection) outbreak in 2009 are directly related to microbial aerosols. It can be seen that microbial aerosols pose a huge threat to indoor air quality and human health, and the control of such pollutants is of great significance. [0003] At present, the commonly used methods for killing microorganisms in indoor air are ul...
