The working principle characteristic of off-gas treatment purifying device reachs skill of choose and buy of off-gas treatment purifying device

Environmental protection of Zhejiang grand rich is a major pursues off-gas treatment facility, the manufacturer of waste gas purifying device reachs the industry of construction solution, today of grand rich environmental protection small write everybody introduction: The working principle characteristic of off-gas treatment purifying device reachs skill of choose and buy of off-gas treatment purifying device:

As the ceaseless development of social industry, environmental pollution all the time is not harming the life property security of people, because this environment administers extremely urgent. In last few years haze of autumn winter mist has made people realized the terrible sex that the environment endangers, the country is the punish strength that increased pair of environments more. The country employed many manpower material resources, comprised environmental superintend and director to check group, environmental superintend and director spread out to investigate the work inside countrywide limits. Be aimed at air pollution, waste gas processing, we should choose pair of environmental protection equipment, suit the remedy to the case.

　　 Off-gas treatment purifying device

At present the purifying device of current organic off-gas treatment on market face basically has UV light equipment of adsorption of oxygen catalysis equipment, microtherm plasma equipment, activated carbon, gush drenchs tower this 4 kinds big. Today of grand rich environmental protection small make up the working principle that introduce these a few waste gas to administer environmental protection equipment to everybody and characteristic!

　　 1, the working principle of off-gas treatment purifying device:

Catalysis of UV smooth oxygen is to use irradiation of tailor-made beam of light of ultraviolet ray of UV of high-energy tall ozone waste gas, use the molecular key of the bacterium in waste gas of industry of splitting decomposition of high-energy UV beam of light, the nucleic acid that destroys a bacterium (DNA) , undertaking oxidizing reacting through ozone, achieve thoroughly purify reach the goal that exterminates bacterium.

Microtherm plasma is outer undertake decomposing to the element below the effect that adds electric field, make contaminant element happens in cutty time decompose, the active such as a large number of OH that arise at the same time, HO2, O the O3 with freedom radical and extremely strong oxidisability, produce chemical reaction with harmful gas element, in order to achieve the goal of degradation contaminant.

Gush drenchs tower — acerbity mist waste gas is introduced by wind canal purify a tower, through filling layer, waste gas and hydrogenous oxidation natrium absorb fluid to undertake sufficient contact is absorbed enraging fluid two-phase counteract reaction, after course of acerbity mist waste gas is purified, again classics demist board atmosphere is emited into by fan after dehydration demist.

Activated carbon adsorption is the physisorption that uses activated carbon, chemical adsorption, oxidation, catalysis oxidation and reductive the water treatment method of the contaminant in waiting for function purify water.

　　2, the characteristic of off-gas treatment purifying device:

Equipment of catalysis of UV smooth oxygen does not have pollution 2 times, beardless daily attention, need to receive electrify source only, can work normally, move uphold charge extremely low. It still has the effect that decomposes bacterium of cause of disease and toxin, have very strong antiseptic capacity. Cannot explode combustibly, easily in order to be used at purifying or caustic gas.

Microtherm plasma off-gas treatment is a kind of dry method purifies a process, can handle the gas mixture that a variety of bad smell combine adequately, moving process need not add any additive, do not produce liquid waste, waste residue, won’t cause pollution 2 times, but combustible to high concentration explode easily waste gas, cause explosion extremely easily. Later period needs clear ash.

Device of activated carbon adsorption applies to bad smell of low density, large wind force, to alcohol kind, adipose kind of effect is more apparent. But activated carbon often must change, and need searchs activated carbon deserted processing method, move maintain cost tall.

Gush drenchs the tower can handle a lot of kinds of organic waste gas, apply to organic dissolvent especially or the circumstance with graininess more material, need to be joined regularly spray fluid, and need to be safeguarded regularly, facility moving cost is high.

The actor defect of equipment of these a few kinds of environmental protection each are not identical, the organic waste gas of processing also has certain difference, the environmental protection equipment with the applicable waste gas of different plant institute eduction also is different. , when installing environmental protection equipment, must choose which kinds of equipment according to the property of manufacturer, purify for the processing of waste gas sometimes should use 3 kinds of two device, this needs integrated consideration. Choose the equipment of off-gas treatment environmental protection with an appropriate money, can solve off-gas treatment problem easily not only, and can managing cost and moving cost.

Noting model is a kind of commonly used craft in production of contemporary and plastic treatment, the product uses balata to note normally model and plastic note model, in use process, if the waste gas that this craft produces cannot get effective processing to will cause ruinous effect to atmosphere.

The machine that note model is noting model to heat organic waste gas produces in the process, its bases is total hydrocarbon of firedamp of dust grain content, blame kind wait for harmful material. This waste gas is stimulating odour, contain noxiousness slightly, have greater harm to human body health. The meeting such as the styrene that discharges without the organization, toluene, organic waste gas causes serious pollution to the environment, also can cause to human body health very big damage, so waste gas of plastic plant product line must not weigh processing carelessly.

　　The commonly used handles industrial waste gas equipment on market has the following kinds:

　　 1, water gush drenchs filling tower

Have inside filling tower multilayer filling, can increase gas fluid to interface is accumulated and engage time, make tail gas and absorb fluid to go up to be contacted adequately with board face inside the tower, the pollutant in waste gas is drenching with gush water contacts process work, by water sufficient adsorption, it is good to be able to purify the effect, cost moderate.

Gush drenchs the law has technology the advantage of simple, economy, but gush drenchs remove dust of the law remove dust efficiency has 30%-40% only normally, and because waste gas is organic sex, itself is more difficult dissolve at water, molecular bead diameter is far smaller than droplet much, reason uses water gush to drench the law captures efficiency is inferior, more make its dissolve removes hard.

　　 2, activated carbon filters box

Activated carbon adsorption is those who use activated carbon is porous, the principle of existence appeal and of development. The method of activated carbon adsorption that this craft place uses uses this kind of property of solid surface namely, connect when the porous activated carbon of waste gas and big surface touch, the contaminant in waste gas is in by adsorption surface of activated carbon solid, depart with aeriform mixture thereby, achieve depurative goal.

　　 3, light removes flavour purifier

Pass the irradiation of the ultraviolet ray inside equipment, the O2 rapid splitting decomposition in waste gas becomes active O, achieve waste gas to purify thereby, the end that deodorization handles, the effect has exceeded, cost is high;

Still one is plant is more practical, it is gush drenchs tower + equipment of catalysis of UV smooth oxygen.

Its principle: Industrial waste gas is introduced by wind canal purify a tower, through filling layer, waste gas and hydrogenous oxidation natrium absorb fluid to undertake sufficient contact is absorbed enraging fluid two-phase counteract reaction, after course of industrial waste gas is purified, again classics demist board atmosphere is emited into by fan after dehydration demist. Absorb fluid to in cat head after pressure boost of water pump of tower bottom classics gush drenchs and fall, final circumfluence is used circularly to the end of the tower. The waste gas that did not purify completely is in through UV light oxygen catalysis equipment undertakes 2 times handling, purifying rate can amount to 98% above, can reach country and local level completely.

Above is today of grand rich environmental protection small write everybody introduction: The working principle of off-gas treatment purifying device and characteristic and off-gas treatment purifying device choose skill, [grand rich environmental protection] major pursues off-gas treatment facility, construction of waste gas purifying device and product production research and development are made, waste gas purifying device and construction choose environmental protection of Zhejiang grand rich!
