Description
Technical Field
The invention relates to indoor air disinfection equipment, in particular to an ozone air disinfection machine which can be normally used under the condition that people are in a room.
Background
The ozone sterilization and disinfection effect is reflected in the strong oxidizing property, and is a green broad-spectrum efficient sterilization and disinfection agent recognized globally. The ozone generator is widely used for drinking water disinfection and air disinfection of medical and health institutions, ozone can be automatically reduced into oxygen after 30 to 40 minutes, and secondary pollution caused by chemical residues is avoided. The traditional sterilization and disinfection methods, whether ultraviolet rays or chemical fumigation, have the defects of incomplete sterilization, dead corners, large workload, residual pollution or peculiar smell and the like, and may damage the health of human bodies. If ultraviolet ray is used for disinfection, the disinfection has no effect in places where light cannot irradiate, and has the defects of recession, weak penetrating power, short service life and the like. Chemical fumigation also has disadvantages, such as insignificant bactericidal effects against bacteria and viruses with high resistance.
In the 'GB 28232-2020 ozone sterilizer sanitary requirement', 7.1.2 air sterilization is carried out in a closed space under the condition that no people exist in the room, and the concentration of ozone is 5mg/m 3 ～30 mg/m 3 ”。
In GB/T18202-2000 sanitary Standard for ozone in indoor air 3 Standard the present Standard is expressed as time-average concentration, with 1h average maximum allowable concentration of 0.1mg/m 3 ”。
Ozone stimulates respiratory tract mucosa of human body, and ozone can be smelled out when the concentration of ozone in air reaches 0.15 ppm; according to international standards, 0.5-1ppm can cause discomfort such as dry mouth; cough can be caused when the concentration reaches 1-4 ppm; a strong cough can be caused at 4-10 ppm. Therefore, ozone for sterilization must be used to sterilize air in the absence of human beings, and the air must enter the sterilization chamber after at least 30 minutes. (1ppm =2.14mg/m 3 ）
The indoor air can be disinfected by ozone under the unmanned condition, and the disinfection by ozone under the manned condition needs to meet the following conditions: the disinfection space can only be in the air disinfector, and indoor air is disinfected when circulating to the air disinfector; the ozone concentration of the disinfection space in the air disinfector is required to reach a standard specified value; the ozone concentration in the air discharged from the air sterilizer is lower than a safe value.
Disclosure of Invention
In order to solve the problem of air sterilization by ozone under the condition of people in a room, the invention provides an ozone air sterilizer capable of being co-located by a person, which circulates indoor air to the inside of the ozone air sterilizer to perform high-concentration ozone sterilization treatment and discharges the air after decomposition, thereby achieving the purpose of air sterilization under the condition of people in the room.
The technical scheme adopted by the invention for solving the technical problems is as follows: the ozone air sterilizer capable of being co-located by man-machine is composed of a cabinet body, a high ozone plasma tube, an ozone decomposition catalytic net and a fan, wherein an air inlet is formed below the cabinet body, an air outlet is formed above the cabinet body, and the high ozone plasma tube, the ozone decomposition catalytic net and the fan are sequentially arranged in the cabinet body from bottom to top.
And a high-concentration ozone sensor is arranged between the high-ozone plasma tube and the ozone decomposition catalytic net.
And a low-concentration ozone sensor is arranged between the ozone decomposition catalytic net and the fan.
When the ozone air sterilizer which can be co-located by man-machine works, the fan is started to discharge the air in the cabinet from the air outlet, and negative pressure is formed in the cabinet; external air is sucked from an air inlet below the cabinet body; when the sucked air passes through the high ozone plasma tube, oxygen in the air is ionized to generate high-concentration ozone; the aim of air sterilization is achieved by the inhaled air under the action of high-concentration ozone; the air after disinfection flows through the ozone decomposition catalysis net, and the ozone is instantly decomposed into oxygen through the ozone decomposition catalysis net with high specific surface area, and the oxygen is discharged from the air outlet under the action of the fan.
The monitoring value of the high-concentration ozone sensor controls the high-ozone oxygen plasma tube to be opened and closed, and the high-concentration ozone oxygen plasma tube is closed when reaching a set value and is opened when being lower than the set value.
The low-concentration ozone sensor monitors the decomposition effect of the ozone decomposition catalytic net on ozone, and the decomposition effect is lower than the maximum allowable concentration by 0.1mg/m 3 The normal state is maintained; higher than the maximum allowable concentration by 0.1mg/m 3 The ozone decomposition catalytic net is cleaned.
In order to highlight the technical key point, the known technical contents related to the scheme of the invention are omitted, such as an electric control system, air treatment units which are connected in series and in parallel and combined, a filter screen, a caster wheel and the like.
The invention has the advantages that high-concentration ozone is efficiently disinfected in the cabinet, the ozone is decomposed before the gas in the cabinet is discharged, indoor air is disinfected under the continuous circulation action of the ozone air disinfector which can be co-located by a human-computer, the concentration of the indoor ozone is always lower than the safety value under the protection action of the ozone decomposition catalytic net, and the problem of indoor disinfection by ozone under the condition of someone is solved.
