the difference between them is mainly a purification effect difference. The high-altitude purification rate is relatively low, only about 61%, which is suitable for places where smoke pipes reach the roof and there are no complaints from residents. The price is also affordable, reducing costs. Low-altitude emission is suitable for places where there is no smoke pipe to the roof, the environment is sensitive and there are complaints, and the price is more than five times that of high altitude.

1. Purification efficiency

According to their names, we can also draw the conclusion that high-altitude fume purifier equipment is to discharge the purified fume into the high air, while low-altitude fume purifier equipment is to directly discharge the purified gas into the air. Low-altitude fume purifier equipment is equivalent to being discharged into sensitive areas, so the purification efficiency is much better than that of high-altitude fume purifier equipment.

Generally, the purification efficiency of high-altitude fume purifier equipment can reach 61%-71%, while the purification efficiency of low-altitude fume purifier equipment is over 95%. However, the gases purified by these two kinds of lampblack purifier equipment can meet the requirements of national environmental protection lampblack emission standards.

Second, in terms of price

Relatively speaking, low-altitude fume purification equipment has high purification efficiency and good internal material quality, so it is much more expensive than high-altitude fume purification equipment.

Third, on the pipeline

The fume purifier equipment for high-altitude emission needs to send the purified gas to the high altitude before it is discharged, so it is necessary to install the fume conveying pipeline at the outlet of the fume purifier. The low-altitude lampblack purifier can directly discharge the purified gas into the atmosphere, so there is no need to make lampblack pipes at the outlet.
