AI Technical Summary
Technical Problem
When traditional purification devices process high-temperature, high-humidity, and dusty exhaust gases, water vapor easily condenses into water droplets, causing dust to adhere to the surface of the filter bag, clogging the air pores of the filter bag, reducing purification efficiency and service life.
Method used
The reverse backflushing technology is used to circulate the purified high-temperature clean gas into the backflushing air duct through a circulating fan, which backflushes the purification components to remove dust from the filter bags and prevent them from clogging.
Benefits of technology
It extends the filter bag replacement cycle, improves the purification efficiency of the purification device, and reduces operating and maintenance costs.

Abstract
The utility model discloses a purification device for high-temperature, high-humidity and dust-containing waste gas, which comprises a shell, an air passage group is arranged in the shell, the air passage group comprises an air inlet passage, an air outlet passage and a back-blowing air passage, and the air inlet passage, the air outlet passage and the back-blowing air passage are sequentially arranged in the shell from bottom to top; a circulating fan is arranged between the exhaust passage and the blowback air passage, and is arranged outside the shell; at least one side of the gas channel group is provided with one or more groups of purification components, dust-containing waste gas enters the purification components through the gas inlet channel to be purified and is exhausted through the gas exhaust channel, and gas exhausted from the gas exhaust channel enters the back-blowing gas channel through circulation of the circulating fan to perform back-blowing dust removal on the purification components; purified high-temperature clean gas is used for back flushing the purification assembly, so that water vapor in dust-containing waste gas remained in the purification assembly cannot be condensed into water drops, and the situation that the ventilation capacity is reduced due to the fact that a filter bag is wetted and dust adheres to the filter bag is avoided, so that the replacement cycle of the filter bag is prolonged, the overall purification efficiency of the purification device is improved, and the operation and maintenance cost is reduced.
