How long does activated carbon of off-gas treatment equipment change?

Activated carbon, it is the adsorptive data that uses in water treatment equipment and off-gas treatment equipment, the word that uses in waste gas respect has catalytic combustion facility, device of activated carbon adsorption, machine of an organic whole of smooth oxygen activated carbon, interior of these 3 kinds of equipment needs fill activated carbon, the norms of the activated carbon of fill is not certain and identical.

Activated carbon norms has diamonds look, namely of 100*100*100mm, also have columnar, also have grain state, of these activated carbon change frequency, it is client and the problem that a lot of enterprises care all the time, combine the issue that the client cares, article chapter with respect to You Yunchi is environmental protection little make up take you to understand activated carbon of off-gas treatment equipment how long to change?

The sort of activated carbon has a lot of, have for instance: Globose activated carbon, fiber activated carbon, columnar activated carbon, pulverous activated carbon, beehive activated carbon, fruit carapace activated carbon, coconut shell activated carbon.

Among them beehive activated carbon is very common, and in often be being used to off-gas treatment equipment, because beehive activated carbon has the area that compare a list big, via resistance is little, small hole develops, high adsorptive capacity, service life is long wait for a characteristic, apply generally in air pollution processing. Choose magic art of adsorption of beehive activated carbon, namely waste gas and the contact of porous activated carbon that have big face, the contaminant in waste gas by adsorption, rise to purify action thereby.

Simple for, it is adsorptive efficiency tall, wind block is small, won’t resemble grain activated carbon same, after fill is overmuch, cause difference of effect suction wind, perhaps suck do not use waste gas.

So, how long does the activated carbon of interior of box of activated carbon adsorption change?

As manufacturer, what when we can say this wants to see a design only, design is how long. Of course, convention designs 3 months commonly. All, service life has been decided when the design. General unalterable, because, the quantity of backfill activated carbon is fixed. Discharged chroma also is fixed commonly.

The iodine number of activated carbon use time and activated carbon is relative, with before filtering efficiency is relative also (have dust for instance or of grain content filter, handle the sentence with low efficiency, can grain content and dust adhere to activated carbon surface, make the use time of activated carbon shortens thereby)

Below general requirement, we cannot accurate judgement activated carbon can use how long after all. The saturation because of activated carbon period namely the service life of activated carbon, with material be absorptioned of harmful gas concerned badly, and right by the frequency of adsorptive material desorption. But a few research get, using 20 days or so commonly, take out activated carbon to insolate 3 hours or so below sunshine, the likelihood basks in 9 hours more when sunshine is weak, such action is desorption by adsorbed water element, release the space inside a large number of activated carbon that are taken up by its, such likelihoods are used repeatedly, time is not fixed also, 3~6 the month is possible.

If be equipment of adsorptive desorption catalytic combustion the activated carbon inside, so use time can lengthen 2~3 times, because activated carbon can undertake desorption recycle after adsorptive saturation, so use time also is met corresponding extension.

Much experimentation proves, activated carbon time filters time is shorter, the effect jumps over beautiful, different waste gas chroma also affects the adsorptive time of activated carbon and efficiency, handle efficiency for achieved environmental protection, by saturation of groovy activated carbon deadline is a month surely, according to ” atmosphere controls a principle ” , activated carbon adsorption filters wind speed is 0.3m ～ 0.5m/s, the proposal changes cycle is day of 90 days of ~180.
