Description

Air cleaner
Technical field
This utility model belongs to industrial waste gas purifying technical field.
Background technology
Since the industrial revolution, the flourish of industry provides greatly support for human progress, but a large amount of industrial waste gases containing pollutant such as Carbon bisulfide, hydrogen sulfide, dust produced therewith cause pollution greatly to air, bring high risks to the mankind again simultaneously.
At present, due to applied widely, the good characteristics such as purification efficiency is high, floor space is little, operating costs are low of low-temperature plasma generator technology, had been subjected to pay close attention to widely based on the research and development of the purifier of low-temperature plasma generator technology.Such as Patent No. CN202740991U, the device that patent name is " low-temperature plasma dedusting eliminate the unusual smell clearing machine " utilizes a series of effects such as non-thermal plasma trap to make taste harmful gas form the innocuous substance of single atom and molecule and solid particle, thus reach purification, the advantage of this device is the most single, purify certain harmful gas targetedly, but the multiple harmful gas of single treatment, compensate for the deficiency of existing conventional purge effect, but low-temperature plasma generator can occur multiple uncontrollable chemical reaction when with the reaction of contaminated air, the by-product (mainly containing nitrogen oxides and ozone) produced, directly after discharge, air can be caused severe contamination by it.
For by-product, the technology utilizing adsorbent to purify it again has occurred on market, as the file of Patent No. ZL201210161107.5 discloses " a kind of indoor air-purification device ", this device includes electret fiber filter, low-temperature plasma generator power supply, low-temperature plasma generator, adsoption catalysis bed, the low-temperature ion reactors such as adsoption catalysis bed (the most cellular activated carbon) purification are used to produce by-product, its shortcoming is: after activated carbon uses to a certain extent, adsorption efficiency can decline, the purification efficiency causing this purifier reduces, it is thus desirable to periodic replacement activated carbon, the while of changing troublesome, cost is the highest.
Utility model content
This utility model is intended to provide a kind of easy to use, air cleaner that purification efficiency is high.
This programme air cleaner, including shell, the two ends of shell are respectively air inlet, air outlet, enclosure is sequentially disposed with coarse filtration module, low-temperature plasma generator according to air inlet/outlet direction, photocatalysis module it is disposed with between low-temperature plasma generator and air outlet of casing, in the range of this photocatalysis module includes uviol lamp and is positioned at ultra violet lamp and the carrier board of lattice-shaped, this uviol lamp separates with carrier board or combines, with photocatalyst colloid layer on carrier board.
Beneficial effect: waste gas has been filtered out large-scale particulate matter through coarse filtration template, waste gas is again through low-temperature plasma generator (air dielectric in the high-field electrode ionization gap of this inside reactor can produce low temperature plasma), volatile organic matter in a large amount of high energy active particle decomposable asymmetric choice net waste gas that low-temperature plasma generator is formed, so that major part exhaust emission is eliminated, but this step can produce by-product.By-product forms mixed airflow with waste gas, again by photocatalysis module, owing to being lattice-shaped with the carrier board of photocatalyst colloid layer, by-product can fully contact with photocatalyst colloid layer fully, and in UV illumination, nitrogen oxides is converted into nitrate ion under the catalytic action of photocatalyst and is decomposed, and ozone is broken down into active secondary oxidant under ultraviolet light, the volatile organic matter oxidation that secondary oxidant will originate in mixed airflow again.By-product treatment mechanism of the present invention is entirely different with activated carbon, and photocatalyst itself will not change and be lost, can continual purification pollutants in air under the irradiation of ultraviolet light, it is not necessary to often change, easy to use;It addition, the secondary oxidation reaction (the most secondary oxidant participates in oxidation again) of photocatalysis and ozone be combined with each other, drastically increase the purification efficiency of waste gas.
Further, described photocatalysis template is positioned at carrier two ends and the aluminium foil reflecting layer extended along outer casing inner wall, for uv reflectance, improves light-catalyzed reaction efficiency, and prevents from ultraviolet from passing through shell shell wall damaging people.
Further, described carrier board is fixed by fluid sealant with outer casing inner wall, it is ensured that air-tightness.
Further, described carrier board uviol lamp is bolted in the central square of carrier board so that the illumination of photocatalysis module is more uniform.
Further, uviol lamp is easily damaged, and as being connected with carrier board, needs to take out both entirety, and uviol lamp is connected with outer casing inner wall by bolt, it is simple to individually dismantle uviol lamp during dismounting.
Further, described shell cross section is square, and carrier board is nine grids shapes, and carrier board outer wall coincide with outer casing inner wall shape.
Further, described photocatalyst colloid layer is colloidal tio 2 layer, the strongest catalytic degradation effect.
Further, described coarse filtration module is corrosion resistant plate, it is to avoid corrosion.
