Abstract
The invention discloses an air processor for kitchens and bathrooms, which adopts a photocatalyst technology, and comprises: metal casing, the module of bleeding, particulate matter filtering component, photocatalytic purification and ultraviolet sterilization subassembly, photocatalytic purification, ozone absorption subassembly and display module, install the module of bleeding on the metal casing, install particulate matter filtering component on the inner wall of metal casing one end, the inside cavity of metal casing is photocatalytic purification and ultraviolet sterilization subassembly, photocatalytic purification and ultraviolet sterilization subassembly's internally mounted has photocatalytic purification subassembly. According to the air processor for kitchens and bathrooms, which adopts the photocatalyst technology, the photocatalytic purification component is divided into three parts by utilizing the decomposition requirements of different pollutants under the conditions of different humidity and temperature, so that VOC and ozone are sequentially decomposed, bacteria in gas lose activity under the action of ultraviolet light of UVC wave band, the sterilization effect is achieved, the finally treated gas is discharged with the air freshener in an interaction manner, and the quality of control purification is improved.
Description
Technical Field
The invention relates to the technical field of air processors, in particular to an air processor for kitchens and bathrooms, which adopts a photocatalyst technology.
Background
Air is a necessary condition for human survival, and the quality of air greatly influences the health of people. Studies have shown that at least 90% of a person's life is spent indoors. Although human beings first recognized that atmospheric pollution affects human health, indoor air pollution is actually more serious than outdoor air pollution. Indoor air pollutants are summarized in two broad categories: one is suspended solid contaminants including particulate matter, bacteria, etc.; the other is gas pollutants, including air processors for kitchens and bathrooms, which adopt photocatalyst technology for NO, O3, formaldehyde, volatile Organic Compounds (VOCs) and the like. The carbon granules as main components of inhalable particles have the functions of inhibiting cell differentiation and cell metabolism, stimulating the proliferation of trachea and lung epithelial cells and causing fibrosis to cause asthma, pneumonia, bronchitis, chronic obstructive pulmonary disease and the like. VOCs have neurotoxicity, nephrotoxicity and carcinogenicity. Formaldehyde is absorbed by respiratory tract to stimulate the sense of smell and eyes of human body, and cause throat discomfort or pain. Bacteria and the like may cause cough, allergic reaction, and the like. So-called Sick Building Syndrome (SBS), building association (BRI) and chemical allergies (MCS) are all currently associated with this.
The indoor air pollution source mainly comprises indoor building materials, cooking oil smoke, second-hand smoke and a toilet floor drain. Wherein the kitchen is a stable supplier of indoor pollutants in daily life of people.
The main pollutants in the kitchen mainly include oil smoke, volatilization of cleaning agents and the like. When the edible oil is heated to 250 ℃, pungent acrolein is generated, and the acrid acrolein can stimulate respiratory systems such as throat, and respiratory diseases are caused. Students collected peanut oil fume at 200 ℃ and detected 99 volatile substances. The kitchen air sample is analyzed, 5 kinds of polycyclic aromatic hydrocarbons with strong carcinogenicity, such as benzopyrene, exist, wherein the benzopyrene serving as the first found environmental chemical carcinogen can cause the chromosome damage of human cells, and researches show that cooks and housewives in the cooking environment for a long time have high lung cancer incidence. After the range hood is used for a long time, oil stains and dust can be fully accumulated, the efficiency is reduced, and if the pollutants cannot be timely pumped away, the pollutants can be diffused to adjacent spaces such as a living room. And accumulated oil stains are not cleaned timely, bacteria can be bred, and accordingly the number of floating bacterial colonies exceeds the standard. Under the influence of epidemic situations, inhibition methods of viruses or bacteria are increasingly emphasized in all social circles.
Ventilation is regarded as the most common means for removing most pollutants from indoor, but as the energy saving requirements of buildings increase, the natural ventilation rate in the indoor is also reduced, so that the problem of removing pollutants by means of indoor ventilation alone cannot meet the requirements of people. The rapid development of urbanization, the requirements of people on air quality are higher and higher, and the continuous development of a novel air cleaning technology, the functions of air purifier products are required to be continuously increased, the types of pollutants to be removed are required to be continuously enlarged, the initial removal of particle pollutants is required to be expanded to the removal of various indoor pollutants such as volatile organic compounds, viruses and microorganisms, and the types of air purifier products are also required to be enriched accordingly.
The photocatalytic technology utilizes the electron and hole pairs excited by a semiconductor material with photocatalytic activity under illumination to participate in photochemical reaction, so as to complete the degradation of organic gases or microbial organic substances, and the reaction can be carried out at normal temperature and normal pressure. The photocatalytic technique is an organic junction of both photochemistry and a catalyst.
The commonly used photocatalyst is N-type conductor material such as TiO 2 、Zn0 2 、WO 3 、SnO 2 、Fe2O 3 Etc. wherein the TiO 2 It is a photocatalyst which is most important because of its good stability and harmlessness to human body. But TiO2 2 As a photocatalyst, there is a limitation that electrons and holes migrate on the surface of TiO2 and are easily recombined with each other, which further reduces the activity of the catalyst. In order to further improve TiO by taking account of the low activity 2 By the photocatalytic properties of TiO 2 The research to modify to obtain new catalysts has been of interest in recent years.
The inventors showed that the photocatalytic reaction is not sensitive to temperature changes, but that temperature has an influence on the reaction system. Meng et al found temperature vs. TiO 2 The photocatalytic activity of the compound has positive influence, and the temperature not only influences the separation, transfer and recombination of carriers, but also influences the subsequent photochemical reaction. Zhang et al found that the rate of photo-assisted decomposition is directly proportional to the temperature, and that temperature rise is favorable for the redox reaction on the semiconductor surface. The increase in reaction temperature also reduces the energy consumption of the catalyst.
Sang Bum Kim et al found that the catalyst reaction rate can be increased also in an environment of suitable humidity. The water vapor participates in the photocatalytic reaction, the superoxide radical can react with water molecules to finally form hydroxyl radical, and the formation of the hydroxyl radical can increase the photocatalytic degradation rate of the VOCs.
