The present invention is achieved through the following technical solutions:
A kind of flue gas ash removal waste heat recovery set composite, comprises air chest, hot water pipeline, waste-heat recoverer and flashback tank; The top of air chest is provided with into fume pipe, bottom air chest, be provided with microporous pipe, is provided with water jacket in microporous pipe outer cover; Be connected with the arrival end of hot water pipeline by pipeline bottom microporous pipe, the port of export of hot water pipeline connects fume pipe; Hot water pipeline is connected with the water inlet end of flashback tank by the water sealing (sealing water) pipe arranged bottom it, and the water side of flashback tank is connected with the water inlet of water jacket by water inlet pipe; The pipeline of flashback tank water side towards water jacket is provided with circulating pump; Waste-heat recoverer is arranged on the outside of hot water pipeline, is provided with the waste heat recovery outlet pipe towards heat user bottom waste-heat recoverer; Water sealing (sealing water) pipe is also provided with the filter for removing grit in the hot water that flows out from hot water pipeline.
The water side of flashback tank is connected by tube connector with circulating pump.
At the hot water pipeline port of export and go out between fume pipe to be also provided with flue gas fairlead.
Waste heat recovery water inlet pipe is also provided with at waste-heat recoverer top.
Water inlet pipe is provided with water intaking valve.
Be connected with the arrival end of hot water pipeline by connecting bend bottom microporous pipe.
Compared with prior art, the present invention has following useful technique effect:
Flue gas ash removal waste heat recovery set composite of the present invention, enter fume pipe and be arranged on air chest top, microporous pipe is provided with bottom air chest, the sheathed water jacket in outside of microporous pipe, water jacket is supplied water by flashback tank, cooling water is injected in microporous pipe by the micropore in microporous pipe and forms water smoke, by the fine particle removing in kiln gas, water smoke has also taken away fume afterheat, cooling water has been become hot water, microporous pipe is connected with hot water pipeline, at hot water pipeline outer setting waste-heat recoverer, afterheat of hot water reclaims and flow in heat user by the working medium in waste-heat recoverer, Decay heat removal is used to heat user.Water is flowed into flashback tank by the water sealing (sealing water) pipe arranged bottom it by hot water pipeline, flows in water jacket by water inlet pipe, continues next circulation.Water sealing (sealing water) pipe being also provided with the filter for removing grit in the hot water that flows out from hot water pipeline, can purifying recirculated water, making water circulation use in system, efficient energy-saving.Structural design advantages of simple of the present invention, floor space is little, energy-conserving and environment-protective, and efficiency of dust collection is high, and power consumption is few, and water consumption is few, be cleaned and the flue gas of lowering the temperature can safety discharged in environment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1, flue gas ash removal waste heat recovery set composite of the present invention, comprises air chest 2, hot water pipeline 8, waste-heat recoverer 11 and flashback tank 16; The top of air chest 2 is provided with into fume pipe 1, is provided with microporous pipe 3 bottom air chest 2, is provided with water jacket 4 in microporous pipe 3 outer cover; Be connected with the arrival end of hot water pipeline 8 by connecting bend 7 bottom microporous pipe 3.The port of export of hot water pipeline 8 connects fume pipe 14, at hot water pipeline 8 port of export and go out between fume pipe 14 to be also provided with flue gas fairlead 13.
Hot water pipeline 8 is connected with the water inlet end of flashback tank 16 by the water sealing (sealing water) pipe 15 arranged bottom it, and the water side of flashback tank 16 is connected with the water inlet of water jacket 4 by water inlet pipe 5, and water inlet pipe 5 is provided with water intaking valve 6.The pipeline of flashback tank 16 water side towards water jacket 4 is provided with circulating pump 19, and the water side of flashback tank 16 is connected by tube connector 18 with circulating pump 19; Waste-heat recoverer 11 is arranged on the outside of hot water pipeline 8, is provided with the waste heat recovery outlet pipe 9 towards heat user 10 bottom waste-heat recoverer 11, and waste-heat recoverer 11 top is also provided with waste heat recovery water inlet pipe 12.
Preferably, water sealing (sealing water) pipe 15 is also provided with the filter 17 of grit in the hot water for removing outflow from hot water pipeline 8.
Flue gas ash removal waste heat recovery set composite of the present invention, operationally:
Flue gas from kiln flow into air chest 2 from entering fume pipe 1, and flow in the microporous pipe 3 arranged bottom air chest 2.In microporous pipe 3, be driven into water inlet pipe 5 from flashback tank 16 by circulating pump 19 and flow into the cooling water water jacket 4, being injected in microporous pipe by the micropore in microporous pipe 3 and forming water smoke, the fine particle in flue gas is removed.Meanwhile, water smoke has also taken away fume afterheat, and cooling water has been become hot water, and flow in waste-heat recoverer 11.In hot water pipeline 8, afterheat of hot water reclaims and flow in heat user 10 by the working medium in waste-heat recoverer 11, Decay heat removal is used to heat user, hot water cooling in hot water pipeline 8, after water sealing (sealing water) pipe 15 is removed grit by filter 17, purify waste water and flow in flashback tank 16, be recycled pump 19 and squeeze in water jacket 4, continue next circulation.Cleaned flue gas flow into out fume pipe 14 from flue gas fairlead 13, leaves dust arrester.The advantage of this device is: energy-conserving and environment-protective, and efficiency of dust collection is high, and power consumption is few, and water consumption is few.
