Description
Technical field
The present invention relates to a kind of high-temperature flue gas waste heat recovery and bag-type dusting integrated apparatus, it is mainly used in petrochemical industry and urges
Change waste heat recovery and the bag-type dusting of cracking boiler smoke, coal-burned industrial boiler flue gas and industrial furnace smoke, be a kind of energy-conservation
Environmental protecting device.
Background technology
Petrochemical industry catalytic cracking boiler smoke, coal-burned industrial boiler flue gas and industrial furnace smoke generally all have temperature
High, the characteristics of containing fine dust, traditional flue gas purifying technique are first cooling, dedusting again, i.e., a heat exchanger are first used, by cigarette
The near sack cleaner license temperature in use of temperature degree, while recovery waste heat；A sack cleaner is reused, is removed in flue gas
Dust, reach gas cleaning purpose.Two equipment are in one line, series operation.
There is obvious deficiency and limitation in above-mentioned traditional high-temperature flue gas purification technique, be mainly manifested in 3 aspects：When
Two equipment are required for configuring ash discharge and ash conveying device, high energy consumption, repair and maintenance amount are big；Second, two equipment are both needed to individually adopt
Purchase and configure independent foundation of civil work, investment is high；Third, floor space is big, some occasion places are limited, and lead to not implement.
At present, also not by heat recovery technology integrated with bag type dust removing technology compound relevant report, data and work
Journey case.
The content of the invention
The present invention is for high energy consumption, repair and maintenance amount existing for above-mentioned traditional flue gas purifying technique are big, investment is high and takes up an area
The shortcomings of area is big, the present invention provide a kind of high-temperature flue gas waste heat recovery and bag-type dusting integrated apparatus so that high-temperature flue gas
Cooling, waste heat recovery and bag-type dusting are carried out simultaneously in integrated apparatus, effectively solve the problems, such as that background technology is present.
The present invention technical solution be：High-temperature flue gas waste heat recovery and bag-type dusting integrated apparatus, including heat exchange
Device and sack cleaner, it is intraoral that the heat exchanger is arranged on entering for the sack cleaner, or is arranged on sack cleaner and enters
In casing at mouthful；High-temperature flue gas enters first through heat exchanger cooling and waste heat recovery after device, then efficient through sack cleaner
Bag-type dusting.
The heat exchanger includes header, snakelike convection bank, heat exchanger deashing device, and header is welded with snakelike convection bank
Connect, heat exchanger deashing device is arranged on the top or side of snakelike convection bank, cooling medium in snakelike convection bank, Ye Shire
Recovering medium is water or air.
The snakelike convection bank is steel pipe, or finned metal tube.
The heat exchanger deashing device is sound wave ash cleaner, or air bubble, or ash removal equipment for flapping；Sound wave
High energy sound wave is produced when deashing device works to snakelike convection bank deashing；Air bubble is then blown to snakelike right using compressed gas
Flowing bundle deashing；Rapping apparatus then taps snakelike convection bank deashing using beater.
The sack cleaner includes import, middle case, upper box, ash bucket, filter bag, pulse spraying equipment；Import is installed
In middle case airintake direction side, middle case top installation upper box, filter bag is suspended on the card of upper box, set in upper box
Put pulse jetting deashing device；The lower section installation ash bucket of middle case.
High-temperature flue gas waste heat recovery and the operation principle of bag-type dusting integrated apparatus are：It is first after flue gas flows into import
Snakelike convection bank is first passed through to cool down it, while water or air in heating tube bundle, realize waste heat recovery；After cooling
Flue gas again through sock filtration, so as to realize that dust granules remove from flue gas, the flue gas after purification is arranged from the afterbody of upper box
Go out；
After a certain amount of dust is adhered in snakelike convection bank, heat exchanger deashing device is started working, to snakelike convection bank
Deashing is carried out, the dust to come off is fallen into ash bucket；After filter bag surface attachment a certain amount of dust, filtration resistance uprises, pulse spray
Blowing-out apparatus for ash is started working, and to filter bag ash removal, the dust to come off is fallen into ash bucket.
The beneficial effects of the invention are as follows：Waste heat recovery and bag-type dusting are organically combined into an entirety, in a device
It is upper to realize high-temperature flue gas cooling, waste heat recovery and efficient bag-type dusting simultaneously, the device space is taken full advantage of, simplifies high temperature cigarette
Gas purification technique, reduces number of devices, energy consumption, construction investment and floor space, easy access and maintenance, is suitable for newly-built ring
Guarantor's project and the transformation of old factory's green technology.
