Description
Technical field
The present invention relates to a kind of high-temperature flue gas waste heat recovery and bag-type dusting integrated apparatus, be mainly used in petrochemical industry catalytic cracking boiler smoke, coal-burned industrial boiler flue gas and the waste heat recovery of industrial furnace smoke and bag-type dusting, be a kind of energy-saving environmental protection device.
Background technology
Petrochemical industry catalytic cracking boiler smoke, coal-burned industrial boiler flue gas and industrial furnace smoke the most all have that temperature is high, feature containing fine dust, traditional flue gas purifying technique is first cooling, dedusting again, the most first use a heat exchanger, the license of near for flue-gas temperature sack cleaner is used temperature, simultaneously recovery waste heat；Re-use a sack cleaner, remove the dust in flue gas, reach gas cleaning purpose.Two equipment are in one line, series operation.
There is the most not enough and limitation in above-mentioned traditional high-temperature flue gas purification technique, is mainly manifested in 3 aspects: one is that two equipment are required for configuring ash discharge and ash conveying device, and energy consumption is high, and repair and maintenance amount is big；Two is that two equipment are both needed to individually purchase and configure independent foundation of civil work, investment height；Three is that floor space is big, and some occasion place is limited, causes implementing.
At present, the most not by integrated with bag type dust removing technology for heat recovery technology compound relevant report, data and Engineering Projects.
Summary of the invention
The shortcoming such as the present invention is directed to that the energy consumption that above-mentioned tradition flue gas purifying technique exists is high, repair and maintenance amount big, investment high and floor space is big, the present invention provides a kind of high-temperature flue gas waste heat recovery and bag-type dusting integrated apparatus, cooling high-temperature fume, waste heat recovery and bag-type dusting are carried out in integrated apparatus simultaneously, effectively solves the problem that background technology exists.
The technical solution of the present invention is: high-temperature flue gas waste heat recovery and bag-type dusting integrated apparatus, including heat exchanger and sack cleaner, described heat exchanger is arranged in the import of described sack cleaner, or is arranged in the casing of sack cleaner import department；First high-temperature flue gas cools down and waste heat recovery through heat exchanger after entering device, then through the efficient bag-type dusting of sack cleaner.
Described heat exchanger includes header, snakelike convection bank, heat exchanger deashing device, header is welded with snakelike convection bank, heat exchanger deashing device is arranged on top or the side of snakelike convection bank, cooling medium in snakelike convection bank, be also recuperation of heat medium be water or air.
Described snakelike convection bank is steel pipe, or finned metal tube.
Described heat exchanger deashing device is sound wave ash cleaner, or air bubble, or ash removal equipment for flapping；High energy sound wave is produced to snakelike convection bank deashing during sound wave ash cleaner work；Air bubble then utilizes compressed gas to jet to snakelike convection bank deashing；Rapping apparatus then utilizes beater to tap snakelike convection bank deashing.
Described sack cleaner includes import, middle casing, upper box, ash bucket, filter bag, pulse spraying equipment；Import is arranged on middle casing airintake direction side, and casing is installed on middle casing top, and filter bag is suspended on the card of upper box, arranges pulse jetting deashing device in upper box；Ash bucket is installed in the lower section of middle casing.
High-temperature flue gas waste heat recovery with the operation principle of bag-type dusting integrated apparatus is: after flue gas flows into import, first passes through snakelike convection bank and cools down it, simultaneously the water in heating tube bundle or air, it is achieved waste heat recovery；Flue gas after cooling is again through sock filtration, thus realizes dust granules and remove from flue gas, and the flue gas after purification is discharged from the afterbody of upper box；
After a certain amount of dust is adhered in snakelike convection bank, heat exchanger deashing device is started working, and snakelike convection bank is carried out deashing, and the dust come off falls in ash bucket；When after a certain amount of dust of filter bag surface attachment, filtration resistance uprises, and pulse jetting deashing device is started working, and to filter bag ash removal, the dust come off falls in ash bucket.
The invention has the beneficial effects as follows: waste heat recovery is organically combined into bag-type dusting an entirety, a device realizes high-temperature flue gas cooling, waste heat recovery and efficient bag-type dusting simultaneously, take full advantage of the device space, simplify high-temperature flue gas purification technique, reduce number of devices, energy consumption, construction investment and floor space, easy access and maintenance, be suitable for newly-built environmental protection project and the green technology transformation of old factory.
