Problems solved by technology

However, chemical disinfectants also have their disadvantages, such as peracetic acid, which is irritating to eyes and skin mucous membranes, corrosive to metal objects, and damages textiles; The bactericidal effect is not strong
Ultraviolet radiation is a classic and traditional air disinfection method. However, its limitation is that the radiation does not reach the corners and it is easy to form dead ends. In addition, no one can enter during the disinfection process.
Although the effect of air cleaner is relatively long-lasting, its sterilizing power is far less than that of chemical disinfectants

Embodiment 1

[0011] Atomize 1000mL of slightly acidic electrolyzed water with a pH of 4.65, ACC of 30mg / L, and ORP of 700mV and spray it in a closed and unventilated room (4.9m×2.8m×2.7m), and place the atomizer in the room In the center, the height is 0.8m from the ground, and the atomization flow rate is 200mL / h. After multiple tests, the initial total number of colonies in the room is 200-750cfu / m 3 Under certain conditions, the sterilization rate of atomization for 15 minutes is above 25%.

Embodiment 2

[0013] Atomize 1000mL of slightly acidic electrolyzed water with a pH of 6.5, ACC of 10mg / L, and ORP of 700mV and spray it in a closed and unventilated room (4.9m×2.8m×2.7m), and place the atomizer in the room In the center, the height is 0.8m from the ground, and the atomization flow rate is about 250mL / h. After multiple tests, the initial total number of colonies in the room is 200-750cfu / m 3 Under certain conditions, the sterilization rate of atomization for 30 minutes is above 50%.

Embodiment 3

[0015] Atomize 1000mL of slightly acidic electrolyzed water with a pH of 4.5, ACC of 30mg / L, and ORP of 900mV and spray it in a closed and unventilated room (4.9m×2.8m×2.7m), and place the atomizer in the room In the center, the height is 0.8m from the ground, and the atomization flow rate is about 300mL / h. After multiple tests, the total number of initial bacterial colonies in the room is greater than 750cfu / m 3 Under certain conditions, the sterilization rate of atomization for 30 minutes is above 60%.

Abstract

The invention discloses a method for reducing microbial pollution in indoor air. The method comprises the following steps: atomizing slightly acidic electrolyzed water for 15-120 minutes, and jetting the slightly acidic electrolyzed water into the air at a flow rate of 200-300 mL / h, wherein the effective chlorine concentration of the slightly acidic electrolyzed water is 10-30 mg / L, the pH is 4.5-6.5, and the oxidation reduction potential is 700-900 mV. The method disclosed by the invention can be used for indoor sterilizing with people and effectively reducing microbial pollution in the air without corroding furniture, so that no additional protection measure is carried out on indoor decorations, and in addition, the method can also be used for achieving the function of a traditional air humidifier to perfect the indoor air quality by adjusting the relative humidity of the indoor air; the method disclosed by the invention is convenient, efficient and is conducive to promotion and application.

Description

technical field [0001] The invention relates to a method for reducing microbial pollution in indoor air. Background technique [0002] Indoor air pollution mainly refers to the introduction of pollution sources that can release harmful substances indoors or poor ventilation in the indoor environment, which increases the number or types of harmful substances in the indoor air, causing harmful changes in air components, and causing human pollution. A series of uncomfortable symptoms appeared. Modern people spend more than 80% of their lives indoors. Specific studies have shown that the concentration of pollutants in indoor air is close to 2 to 5 times that of outdoors. It can be seen that the requirements for indoor air quality come from a certain extent. Said even higher than the outdoors. [0003] Microorganisms in indoor air are typical representatives of indoor air pollutants, which can easily cause eye irritation, asthma, dermatitis, pneumonia and other infectious disea...
