Detailed Description
In order to further describe the technical means and effects adopted by the invention for achieving the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the invention with reference to the attached drawings and the preferred embodiment.
Referring to fig. 1, the embodiment provides an air purifying comprehensive treatment method based on a photocatalyst technology, which includes the following steps:
s1: selecting a common ground, wetting with water, and measuring the pH value of the ground to be a comparison value by adopting pH test paper;
s2: removing benzene and fungus, spraying acetic acid preparation on the common ground, volatilizing acetic acid into air, thereby removing benzene and fungus in air, accelerating air purification time, spraying acetic acid Y in unit area, and keeping room height as H, wherein Y=2 H The acetic acid spraying amount Y and the room height H are exponentially increased, and the room height is between 3 and 6 meters under normal conditions, so that the required acetic acid spraying amount Y is 8ml when the room height is 3 meters, and the required acetic acid spraying amount Y is 64ml when the room height is 6 meters;
s3: the humidity of the room is increased by the humidifier because the larger the humidity is, the more moisture molecules are in the unit volume of air because moisture molecules (H 2 O) to nitrogen (N) 2 ) Oxygen (O) 2 ) The air density becomes smaller, the pressure is reduced, and the lower the pressure is, the faster the volatilization of the acetic acid is caused, so the relation between the humidity S and the acetic acid spraying amount Y is as follows: s=2/Y, that is, the humidity S is inversely proportional to the acetic acid spraying amount Y, when the humidity is high, the faster the acetic acid molecules diffuse into the air, the amount of acetic acid needed in unit time is certain, so that the spraying amount Y is smaller;
s4: standing, wherein the relation between the volatilization time t of acetic acid and the humidity S and the acetic acid spraying amount Y is as follows: t=s/Y, where when the humidity is constant, the acetic acid spray amount Y increases, the longer the acetic acid volatilization time t, and when the acetic acid spray amount Y is constant, the greater the humidity S, the smaller the pressure, the shorter the acetic acid volatilization time t;
s5: the secondary wiping is carried out on the common ground surface by using the pH test paper, the pH value is recorded, and the comparison value in the step S1 is compared to judge whether the acid on the common ground surface is completely volatilized, the secondary wiping is carried out on the common ground surface by using the pH test paper, if the common ground surface is dry at the moment, the test is carried out after the common ground surface is wetted by water like the step S1, the pH value of the secondary wiping is compared to judge whether the acetic acid is completely volatilized, and the subsequent formaldehyde removal treatment is carried out comprehensively to avoid mutual influence, so that the formaldehyde removal treatment can be carried out only after the acetic acid is completely volatilized;
s6: if the judgment result in the step S5 is yes, the next step of processing is carried out; if the judgment result in the step S5 is no, the humidity and the standing time are continuously increased, the purpose of the next step is to ensure that the acetic acid preparation is completely volatilized, if the acetic acid preparation is not completely volatilized, the step S7 of formaldehyde removal treatment is performed, the spraying of the photo-catalyst preparation is started, a layer of non-volatilized complete acetic acid preparation can be formed between the photo-catalyst preparation and the ground, at the moment, the photo-catalyst preparation cannot be in direct contact with the ground, the effect of removing formaldehyde of the photo-catalyst preparation in a region shielded by the non-volatilized complete acetic acid preparation is poor, and secondly, the step S7 is to mention that the photo-catalyst preparation is sprayed, the photo-catalyst preparation is solidified into a film, at the moment, the film formed by solidifying the non-volatilized acetic acid preparation by the photo-catalyst preparation is sealed inside, and after the photo-catalyst preparation is processed by air, the acetic acid preparation begins to volatilize, which is contrary to the situation of increasing the air purification efficiency to be solved;
s7: removing formaldehyde, spraying with photocatalyst, solidifying to form film,
the photocatalyst is solidified into a film, which generally needs 2-3 days for natural drying, and the photocatalyst can be accelerated to be solidified into a film by blowing by a fan, and the ultraviolet light source equipment is used for the filmThe film solidified by the photocatalyst is irradiated, because the ultraviolet lamp 4 of the ultraviolet light source device can lead electrons (e-) on the valence band of the photocatalyst to be transited to a conduction band, corresponding holes (h+) are generated on the valence band, and super-oxygen ion free radicals, hydroxyl free radicals and super-oxygen hydroxyl free radicals with extremely strong oxidation effect are generated, and toxic and harmful gases such as formaldehyde and the like can be oxidized and decomposed into harmless CO 2 And H 2 O, natural light or fluorescent lamp can make the speed of purifying air by photocatalyst slower;
s8: and (3) ventilation treatment, wherein the ventilation treatment can further accelerate the solidification and film formation time of the photocatalyst.
At present, in the comprehensive air purification treatment method based on the photocatalyst technology, usually, a photocatalyst is adopted to make electrons (e < - >) on a valence band transition to a conduction band under the action of light, corresponding holes (h < + >) are generated on the valence band, and super-oxygen ion free radicals, hydroxyl free radicals and super-oxygen hydroxyl free radicals with extremely strong oxidation action are generated, so that toxic and harmful gases such as formaldehyde, pollutants, odor, bacteria and the like can be oxidized and decomposed into harmless CO 2 And H 2 O, has high-efficient broad-spectrum disinfection performance, has good inhibition and killing effects on various common pathogenic bacteria, does not change and consume in the photocatalyst action process, only provides one reaction place, does not produce secondary pollution, but has more formaldehyde and benzene content for building rooms, and also contains some fungi and tasty gas, and the treatment of formaldehyde and benzene only by the photocatalyst can lead to slow efficiency, generally requires 7-15 days to be treated cleanly, and can influence the use efficiency of the rooms in the period.
In order to solve the problem of slow air comprehensive treatment efficiency, in the embodiment, in the step S1, a common ground is selected, wetted with water, the pH value of the common ground is measured to be a contrast value by adopting pH test paper, then acetic acid preparation is sprayed on the common ground, the spraying amount of the acetic acid preparation is changed along with the height change of a room, a humidifier is arranged in the room, the humidity of the room is increased by the humidifier, so that the volatilization speed of the acetic acid preparation is improved, and the acetic acid preparation is volatilized into the air to volatilize the airBenzene and fungi and some odorous gases are removed firstly, so that the polluted gas in the air is reduced, then the acetic acid preparation is completely volatilized, then the spraying treatment is carried out by adopting a photocatalyst, after the photocatalyst is solidified into a film, the film solidified by the photocatalyst can be irradiated by ultraviolet light source equipment, at the moment, the superoxide ion free radical, hydroxyl free radical and superoxide hydroxyl free radical generated by the photocatalyst are combined with formaldehyde, ammonia, radon and other harmful gases in the air more easily, so that the formaldehyde, ammonia, radon and other harmful gases are decomposed into harmless CO 2 And H 2 And O greatly improves the air purification rate, so that the room can be put into use as soon as possible.
In order to avoid the influence of dust in the room on the benzene and fungus removal treatment and formaldehyde removal treatment, in one embodiment, before step S1, the room needs to be cleaned to ensure no dust coverage in the room, specifically, furniture articles, building boards, common ground surfaces and wall surfaces in the room need to be cleaned, and after cleaning, the furniture articles, building boards, common ground surfaces and wall surfaces in the room are dried, and then step S1 and subsequent operations are performed.
In order to better spray the photocatalyst on furniture articles, building boards, common ground surfaces and wall surfaces, in one embodiment, the method of spraying the photocatalyst in step S7 is as follows: the spraying pot is used for uniformly spraying, the spraying pot is a spraying pot special for spraying photocatalyst on the market, and the spraying pot is uniformly coated with a slightly wet rag or brush, so that uniformity is guaranteed, excessive spraying in some places is avoided, excessive spraying in some places is too little, water marks or water stains cannot be formed on the surface of an object to be treated or the ground, spraying is required to be uniformly carried out during the spraying process, the photocatalyst is prevented from being air-dried to form a film after the spraying is finished, and a fan is adopted to blow the place on which the photocatalyst is sprayed after the spraying and the coating are carried out, so that the solidification of the photocatalyst to form a film can be accelerated.
