The operation principle of flue gas ash removal and the waste heat recovery circulatory system:
Please refer to Fig. 2, Fig. 2 is the structural representation of the flue gas waste heat recovery apparatus of the utility model flue gas ash removal and the waste heat recovery circulatory system.
When use, steam-generating bank 2 is arranged in flue, in steam-generating bank 2, there is low-temperature receiver water (water filling into is through sewage disposal system water after treatment or the direct moisturizing from the external world) in the time that water is lossy, the quantity of steam-generating bank 2 can increase according to actual needs or reduce, steam-generating bank 2 is communicated with drum 1 by pipeline, when smoke gas flow during by steam-generating bank 2 and steam-generating bank 2 carry out heat exchange, along with the rising of steam-generating bank 2 tube wall temperatures, water temperature in steam-generating bank 2 also raises gradually, in the time reaching certain temperature, water vapor enters into drum 1 by pipeline, steam in drum 1 enters into steam heater 3 by steam fairlead 4, steam mixes with the water being injected in steam heater 3 by the filling pipe 6 of steam heater 3 in advance, the efficiency of steam and water Hybrid Heating will be far away higher than traditional mode water being heated through intermediary, improve the ratio to flue gas waste heat recovery, water sub-fraction through heating is returned in drum 1 by drum water pipe 5, other water through heating enter in the casing 9 of powder purification apparatus by outlet conduit 7 or lead to other heating equipments.
Please refer to Fig. 3, Fig. 3 is the structural representation of the powder purification apparatus of the utility model flue gas ash removal and the waste heat recovery circulatory system.
By interior casing 9 injected water, the connector that water injection rate will ensure to flood circulating water pipe 15 and casing 9 belows makes between overflow plate 11 and the water surface, to have certain distance simultaneously, flue gas after heat exchange enters in blast pipe 10, under the effect of dedusting fan, enter in casing 9 by the air inlet of blast pipe 10, while is due to the effect of dedusting fan wind-force, water in casing 9 is splash, forming tiny water smoke contacts with the dust of pipeline, there is the processes such as wetting, cohesion, diffusion sedimentation, by the purified treatment for the first time in casing 9 of dust in pipeline; Spray head 14 sprays water on the overflow plate 11 in casing 9, due to the mobility of water, do not flow down formation water curtain with the edge of casing 9 inwalls sealings at overflow plate 11, allow contain dust air-flow when by water curtain again fully contact there is wetting, cohesion, the dust in pipeline carried out to double purification processing; The water smoke spraying through spray head 14 again in the interior uphill process of casing 9 through the dust-containing air stream of after-treatment purifies again, realizes the purified treatment for the third time of dust, is finally discharged by the air outlet 16 of overflow plate 11 tops through three air-flows after treatment.
Spray head 14 quantity that arrange on shower can cover whole casing 9 inner chambers with its water spray area coverage and be advisable; The spray head 14 that adopts self-suction circulating water pump 8 to supply with casing 9 tops from drawing water in casing 9 sprays in water tank, only have in the time that the water in casing 9 contains dust and too much affects the clean-up effect of equipment, just the sewage in casing 9 need to be discharged from delivery port 17, re-inject new water (water re-injecting can for by outlet conduit 7 to the water filling in casing 9 with through sewage disposal system water after treatment, if can also directly fill into water in casing 9 from the external world not), save greatly resource; In the time that the sedimentation of dust causes the water surface to be increased to overflow pipe 12 place, the water of rising can flow out casing 9 from overflow pipe 12 and enter into sewage disposal system, can not raise and not have the air inlet of blast pipe 10 to cause equipment normally to work because the water surface is undue; Air outlet 16 be positioned at overflow plate 11 directly over the air-flow that can ensure to contain dust when continuing to rise after water curtain due to the casing 9 (barrier effect on upper top, the air-flow that contains dust could be discharged from air outlet 16 after the interior lateral flow of casing 9, can make like this dust-containing air stream can accept to greatest extent the spray of spray head 14, there is better adsorbing powder dust effect.
Please refer to Fig. 4, Fig. 4 is the structural representation of the sewage disposal system of the utility model flue gas ash removal and the waste heat recovery circulatory system.
Enter into from the sewage of casing 9 interior discharges in the first order artificial swamp filtration system of sewage disposal system, then after five layers of filtration, impurity, mud etc. in water is stopped layer by layer by stone and settlement effect is filtered, water after treatment enters into collecting-tank 19, water in collecting-tank 19 is can be again counter to be mended to flue gas waste heat recovery apparatus and powder purification apparatus for use, in the time that the water in collecting-tank 19 is not enough to supply with both and uses, can also in collecting-tank 19, pump into water from the external world.
Sewage disposal system can also be two or more artificial swamp class settling tanks that are used alternatingly, make dust settling in sewage at the bottom of pond by natural subsidence,, enable other settling tanks flue gas waste heat recovery apparatus and powder purification apparatus are carried out to moisturizing during in natural subsidence at a settling tank.
Above-described embodiment is only for the utility model creation example is clearly described, and not the utility model is created the restriction of detailed description of the invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.All any apparent variations of being extended out within spirit of the present utility model and principle or variation are still among the utility model is created the protection domain of claim.
