Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Embodiment:
Present embodiment has provided a preferred forms of the present utility model.
Referring to Fig. 1, a kind of boiler smoke abatement heat-exchange system has a process tank 6, and a spray equipment 18 is arranged at this process tank top; A reaction tank 22 is arranged, and one grade of slag plate 21 is arranged at the top of this reaction tank, and a filter 23 is arranged at the bottom; The reaction tank both sides are provided with detritus tank 24 and catch basin 11; Deslagging pump 10 is arranged in the detritus tank, and scum pipe 12 ports of this deslagging pump place the top of grade slag plate; Immersible pump 9 is arranged in the catch basin, and this immersible pump is communicated with by the waste water import of pipeline 16 with heat pump conversion unit 3; The middle part of process tank is communicated with boiler exhaust gas mouth and reaction tank by pipeline 13,15 respectively; Drainpipe 8 is arranged at the bottom of process tank, and this drainpipe port places the top of reaction tank; Scum pipe 7 is arranged at the bottom of process tank, and this scum pipe port places in the detritus tank; The wastewater outlet of heat pump conversion unit is communicated with by the spray equipment of pipeline 5 with the process tank top, and the cooling water inlet of heat pump conversion unit is communicated with the return pipe 2 of boiler, and the hot water outlet of heat pump conversion unit is communicated with the boiler blow-down water mouth by pipeline 4.
In the present embodiment, the bottom drainpipe port of process tank is equipped with spray equipment 17.Can make water distribution even, improve the heat exchange effect of interior flue dust of reaction tank and water.
In the present embodiment, there is a blower fan 19 top of reaction tank, and this blower fan is communicated with process tank top by pipeline 14.
Operation principle of the present utility model is:
1, flue dust circulation heat exchange process
The coal smoke that boiler 1 produces 13 enters process tank 6 by the road, and the cold water that is gone out by 3 heat exchanges of heat pump conversion unit enters 6 pairs of flue dust of process tank by pipeline 5 to carry out spraying cooling and handle, and finishes the power conversion of first step water and flue dust; Remaining flue dust and waste water enter reaction tank 22 via pipeline 15 and drainpipe 8 respectively, finish the power conversion of the second step water and flue dust.
The port of the bottom drainpipe 8 of process tank can be installed a spray equipment 17.Can make water distribution even, improve the heat exchange effect of interior flue dust of reaction tank and water.
The residue flue dust can directly enter atmosphere in the reaction tank, a blower fan 19 also can be installed will remain flue dust and 14 draw back recirculation participation flue dust circulation heat exchange process in the process tank 6 by the road.
2, water circulation heat exchange process
Water circulation heat exchange process mainly is to carry out the heat exchange circulation by heat pump conversion unit.The one, the cold water of coming from boiler blow-down water pipe 2 enters heat pump conversion unit, the cold water that the heat that extracts in the thermal wastewater that heat pump conversion unit utilizes pipeline 16 to come is come boiler blow-down water pipe 2 heats, water after the heating 4 returns boiler by the road, has realized the utilization of flue dust used heat.The 2nd, the thermal wastewater in catch basin 16 returns heat pump conversion unit by the road by immersible pump 9 pumpings, and heat pump conversion unit extracts heat in thermal wastewater, with the waste water refrigeration, then cold waste water 5 is entered process tank recirculation by the road.
3, the dirt slag is handled
It mainly is to carry out in reaction tank that the dirt slag is handled.The waste water that has the dirt slag of discharging through scum pipe 7 from the bottom of process tank enters in the detritus tank 24 of reaction tank, send into the top of grade slag plate through scum pipe 12 by the waste water that has deslagging pump 10 will have the dirt slag in the detritus tank, the dirt slag is blocked by the shelves slag plate, reside on grade slag plate, formed the dirt slag blanket 20 that is alkalescence, and waste water enters in the reaction tank.From the waste water that pipeline 8 gets off, be dissolved with so in the coal smoke
2, be acid, be acid waste water when parlkaline dirt slag blanket, carry out neutralization reaction with alkaline dirt slag, make waste water become neutral water, and in reaction tank, carry out the secondary heat exchange with 15 flue dust that enter in the reaction tank by the road with the waste water that gets off from pipeline 12.The thermal wastewater that produces in reaction tank enters catch basin after filtering through filtering layer 23, is pumped into heat pump conversion unit by immersible pump 9 then.
Reside in dirt slag blanket 20 on grade slag plate and be stacked into when a certain amount of, clear up landfill.
