Background technology
Along with the raising of people's quality of life, the pollution that interior decoration brings is day by day serious.In the air cleaning industry, purifier adopts the technology such as mechanical filter, charcoal absorption, Electrostatic Absorption dedusting, negative oxygen ion purification, ozone oxidation, photocatalyst more, but all cuts both ways.Mechanical filter can only effectively be removed the particulate pollutant of certain particle size range in air, to gaseous contaminant, but can't remove, and its performance is perfect not, and overall clean-up effect is not good; There is the absorption saturation state in charcoal absorption, can cause " secondary pollution " and the problem of regenerating active carbon is arranged; The clean-up effect of the particulate pollutant that the Electrostatic Absorption dedusting is larger to particle diameter is better, but can't purify gaseous contaminant, also can produce the secondary pollutions such as ozone simultaneously; The negative oxygen ion purification techniques has certain sterilization and purifies the effect of particulate pollutant, but also can't purify gaseous contaminant, also can produce the secondary pollutions such as ozone simultaneously; While adopting this technology of ozone oxidation to be administered room, the people wants room away from keyboard, avoids ozone poisoning purification, to control, brings some inconvenience, and in addition, the residual ozone of part may damage human body.Photocatalyst technology the time can be divided into two kinds of situations according to the source of ultraviolet light in application: one. and contained trace ultraviolet ray in utilizing available light does not provide separately light source; Two. use ultraviolet lamp that ultraviolet ray is provided.In the first situation, the light-catalyzed reaction degradation efficiency is low; In the second situation, the people must leave, and ultraviolet light easily reveals, and human body is damaged.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good purification, simple in structure, the photocatalysis fluid bed air purifier that uses safety.
The present invention solves the problems of the technologies described above with following technical scheme:
A kind of photocatalysis fluid bed air purifier, used ultraviolet light source, it is characterized in that with activated carbon supported nano-TiO
2for scavenging material, during work, scavenging material, in the fluidisation state, can be realized the original position reparation of scavenging material, and consistent electric field is set in fluidized bed body, promotes the carrying out of light-catalyzed reaction, and air-treatment is sequentially first dry after-purification.
Device structure of the present invention is: relative positive electrode plate and negative electrode plate are arranged in electrode chamber, and there is ultraviolet light source at center, and filter pulp is taken in the upper end of positive electrode plate, negative electrode plate and ultraviolet light source, lower termination the second dispersion plate; The silica dehydrator layer is arranged at the bottom of electrode chamber, and there is the first dispersion plate silica dehydrator layer lower end: there is the air inlet pipe be connected with asepwirator pump the lower end of shell, and there is gas outlet upper end.
Loaded with nano TiO is housed in electrode chamber
2activated carbon granule.Its granularity is 0.1-0.3mm.
Photocatalysis fluid bed air purifier of the present invention, can decompose forcefully the harmful substances such as airborne formaldehyde, for middle severe formaldehyde pollution air purification efficiency more than 90%, photochemical catalytic oxidation is converted into carbon dioxide and water by poisonous and harmful substance, remove airborne planktonic bacteria and virus, it is lost activity.The light-catalyzed reaction design is carried out in an airtight environment, can effectively avoid the injury of purification process medium ultraviolet light to human body, and nano-TiO
2can keep long-time high-efficient purification effect with active carbon, simple in structure, use safely, occupy little space.The invention solves the in-situ regeneration problem of active carbon, consistent electric field has improved light-catalyzed reaction speed, makes the clean-up effect of device improve, and invest low, for ease of maintenaince maintenance.
