Abstract
The invention discloses an ultraviolet catalytic oxidation deodorizing device, which comprises a shell with a cover plate. An instrument and a control system are arranged on the shell; an odor inlet and a purified gas outlet are formed at front and rear ends of the shell respectively; an air filtering module and an active carbon fiber filtering module which are plugged inside the shell are positioned at the front and rear ends of the shell respectively; and a plurality of photocatalyst modules and ultraviolet lamp modules are plugged between the air filtering module and the active carbon fiber filtering module at intervals. When the odorous gases enter the ultraviolet catalytic oxidation deodorizing device through a collecting system, under the action of ozone and TiO2 catalytic photolysis generated by radiating air through high-energy ultraviolet, the odorous substances in the gases are decomposed and oxidized into CO2 and H2O within the time of more than or equal to 1 second. Therefore, the emission meets the standard.
Description
Technical field
The invention belongs to a kind of odor removal, relate in particular to a kind of ultraviolet catalytic oxidation deodorizing device.
Background technology
Stench is a kind of form of atmospheric pollution, the same sensation public hazards that all belong to noise, and noise directly acts on people's audition, and stench directly acts on people's olfactory sensation, causes harm to the people, gently then does not feel like oneself, heavy then poisoning.Stench has become a kind of in seven kinds of typical public hazards in the world today (atmospheric pollution, water pollution, soil pollution, sound pollution, vibration, land subsidence, stench).China had formulated " odorant pollutant discharge standard " (GB14554-93) in 1993.Standard is pointed out: odorant pollutant is meant that all stimulate organum olfactorium to cause the gaseous matter that people are unhappy and damage living environment.And specifically list the discharge standard of 9 kinds of odorant pollutants (hydrogen sulfide, methanthiol, methyl sulfide, dimethyl disulfide, Carbon bisulfide, ammonia, trimethylamine, styrene, odor concentration).Various countries efforts at environmental protection person was through research and the engineering practice to odor treatment in more than 20 years, developed some more sophisticated odor treatment technology (comprising chemical absorption method, bio-trickling method, masking method, plant extraction liquid catalytic oxidation, absorption method or catalytic type active carbon adsorption, firing method, soil absorption process, ozone deodorization process, low-temperature plasma method, energetic ion method, active oxygen method etc.) but existing technology generally have take up room big, resistance is big, energy consumption is high, equipment investment is high, have secondary pollution problems, and treatment effect waits to improve.Stench is directly proportional for people's sensation amount (being stench intensity) with the logarithm of odorant to the quantity of stimulus of people's olfactory sensation, even odorant removes 90%, but the odor strength that people's olfactory sensation is experienced only reduces less than half.Therefore, the difficulty of odor treatment is very big.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of odor removal and can utilize ultraviolet energy to greatest extent, by UV ozone oxidation, the multiplexing effect of nano titanium oxide ultraviolet catalytic oxidation, to the method that foul gas purifies, reach deodorization and sterilization dual purpose.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of ultraviolet catalytic oxidation deodorizing device, it comprises the shell of plate with cover, shell is provided with instrument and control system, the forward and backward two ends of described shell are respectively arranged with foul smell air inlet and clean gas outlet, be plugged with air filtration module and activated carbon fibre filtering module in the described shell and lay respectively at the forward and backward two ends of shell, be plugged with a plurality of photocatalyst modules and ultraviolet lamp modules between described air filtration module and the activated carbon fibre filtering module at interval.
The invention has the beneficial effects as follows:
1, odor removal efficient height: the discharge capacity and the odor concentration of the odorant pollutant that is discharged after this device is handled all are lower than " odorant pollutant discharge standard " every index request (GB14554-93);
2, occupation area of equipment is little: take up an area of and 1/10 of (as dripping filter tower etc.) the deodorization equipment that takes up space and have only biological treatment;
3, simple to operate, movement-less part need not the personal management, and maintenance expense is low;
4, equipment resistance is less than 100Pa, the power consumption that the reduction system bleeds;
5, deodorant has sterilization efficiently simultaneously;
6, need not add any chemicals, can eliminate redundant ozone automatically, not produce secondary pollution.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a structure cut-away view of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of ultraviolet catalytic oxidation deodorizing device, it comprises the stainless steel casing 1 of plate 11 with cover, shell 1 is provided with instrument and control system 6, the forward and backward two ends of described shell 1 are respectively arranged with foul smell air inlet 12 and clean gas outlet 13, be plugged with air filtration module 2 and activated carbon fibre filtering module 3 in the described shell 1 and lay respectively at the forward and backward two ends of shell, be plugged with a plurality of photocatalyst modules 5 and ultraviolet lamp modules 4 between described air filtration module 2 and the activated carbon fibre filtering module 3 at interval.
The air filtration module 2 that this product uses comprises filters housing 21, filters in the housing 21 and is provided with the stainless (steel) wire 22 that folds, and stainless (steel) wire 22 is provided with fiber filtering filter course 23.The effect of air filtration module 2 is micronic dusts of filtered air, prevents that it from polluting ultraviolet lamp modules 4, guarantees ultraviolet illumination intensity, and fiber filtering filter course 23 can split out replacing as required.
Described photocatalyst module 5 comprises frame 51, be provided with filter screen 52 in the frame 51 by multilamellar rhombus aluminium expanded sheets folds and the Zhe stricture of vagina vertically is formed by stacking mutually, be coated with the titanium dioxide (anatase accounts for 80% mutually, and red metal and stone accounts for 20% mutually) of particle diameter P25 on the described filter screen 52.During making, the titanium dioxide of particle diameter P25 is scattered in the gellant of the anti-high energy electron collision performance excellence that inorganic material forms, the drying activation gets final product on the filter screen 52 in that it is sprayed at.To guarantee to contain on every square metre of filter screen 52 TiO2:40～50g of particle diameter P25 in the time of spraying.Nano-TiO
2To have a particle diameter little because of it, and specific surface area is big, and magnetic is strong, and photocatalysis is good, and absorbent properties are good, and it is strong to absorb the ultraviolet ability, and surface activity is big, and thermal conductance is good, good dispersion, and advantages such as made effect suspension stabilization are the preferred light catalysis material of this device.
