Description
Technical field
The present invention relates to high-temperature flue gas purification and technical field of exhaust heat recovery equipment, more particularly to one kind to have backwash work(
The fume dust remover of energy.
Background technology
The highly energy-consumings such as metallurgy, chemical industry, building materials, maximum discharge industry high temperature flue gas waste heat recovery and purification subtract to China's energy-conservation
Row plays an important roll.Industrial high temperature flue gas has the characteristics that complicated component, dustiness are high, is corrosive, working conditions change is big, makes
Obtain flue gas waste heat recovery and purifier has the bottlenecks such as filter clogging is difficult with regeneration, waste heat recovery and purification efficiency are low and asked
Topic, it would be highly desirable to solve.
High-temperature flue gas purification and waste heat recovery common method mainly have following several：1) first passing through spray mode reduces flue gas
Temperature, while most of dust is removed, dedusting, this method waste heat recovery are then carried out using cloth bag or earthenware filter etc.
Rate is extremely low, secondary pollution be present.2) by high-temperature dust-containing flue gas be introduced directly into waste heat boiler carry out waste heat recovery, be then discharged out compared with
The ash-laden gas of low temperature carries out accurate dedusting, but the high concentration contained in flue gas by cloth bag or earthenware filter etc. again
Dust can form a thick layer slag in boiler wall, increase heat transfer resistance, reduce waste heat recovery efficiency, it is necessary to periodically enter pedestrian
Work removes the gred, and high-temperature flue gas cannot directly enter waste heat boiler because temperature is higher and be cooled down, it is necessary to first pass through water-cooling wall, drop
Low waste heat recovery efficiency.3) first high-temperature flue gas is carried out using the high-temperature dust removing device such as grain bed and earthenware filter net
Change, waste heat recovery then carried out by heat exchanger again, which has higher waste heat recovery efficiency, but due to dust removal process and
Heat transfer process is separately carried out, and temperature adjusting can not be carried out to dust removal process to improve dust removal performance, and cause cleaner volume
Larger, cost is higher；And when high-temperature flue gas contains coagulability grit, earthenware filter easily block after can not deashing, from
And can not regeneration, and filtering material particle easy-to-clean ash and is recycled, in grit containing coagulability due to being formed using discrete spheroid
There is irreplaceable advantage in high temperature fume dust removal.
