Using a kind of Multifunctional smoke energy-saving and emission-reduction system of the present invention, two-stage absorber is added before air-introduced machine, cigarette is absorbed
Partial heat in gas, air-introduced machine rear end is double atomization room 1, and exhaust gas dust enters spray chamber 1, flue gas by smoke inlet 2
In temperature, speed makes spray atomizing pipe 3 spray calcium hydroxide agent and produce atomization to aggravate flue dust weight, by lower liquid level, lower liquid
Face shakes lower liquid level under the effect of above air-introduced machine and flue dust is fallen into the aqueous of casing 6, by double atomization, in flue dust
Sulfur dioxide, itrated compound and calcium hydroxide neutralization reaction reach smoke elimination, dedusting, the purpose of desulphurization and denitration into alkali；Pacify in casing 6
Equipped with the first fluid level controller 10, it is ensured that liquid level can not be too high, the space that otherwise liquid level does not shake is so that the effect of flue dust precipitation
Fruit is not good, and when liquid level reaches critical line, liquid will flow out from the first pre- flow tube 11.There are four water tanks 4 in spray chamber 1（Inhale
Receive device）, have heat absorbing sheet 5 outside water tank 4, inside there is a deflector 7 and fin reinforcing plate 8, flue gas is along empty between the spray chamber 1 of water tank more than 4
Between gap and water tank 4 and water tank 4 space move up and down it is forward, make atomization vapor contact heat absorbing sheet 5, heat absorbing sheet 5 absorb flue gas
Being atomized into the heat of vapor is heated the softened water in water tank 4, and softened water flows in water tank 4 along deflector 7, is leading
When being flowed on stream plate 7, the softened water that the fin reinforcing plate 8 on deflector 7 gives flowing is sufficiently heated, by softening water pipe
13 enter latter water tank 4 by previous water tank 4, softened water is fully heated.Form solidifying after being atomized vapor contact heat absorbing sheet 5
Bear water, remaining vapor makes the water surface produce concussion ripple by 20~30 meters of water beds 14, wind speed by the water surface, and so a large amount of water steam
Gas is reduced with aqueous, above there is baffle 15 top vapor formation condensate is absorbed by absorber 16, along water conservancy diversion plate 17
Outflow, equally, is provided with the second fluid level controller 18, it is ensured that liquid level can not be too high, and otherwise liquid level does not shake in water bed 14
Space causes aqueous vapour reducing not good with the effect in aqueous, when liquid level reaches critical line, and liquid will be from the second pre- flow tube
19 outflows.So by Pyatyi absorb flue gas in heat, by flue-gas temperature be down to by 130 DEG C~180 DEG C 30 DEG C~40 DEG C, summer
Season, with softening tank water formation circulation, improves softening coolant-temperature gage, covers the purpose that boiler reaches energy-conservation of economizing on coal；Winter, heat supply
Using long-range systemic circulation graded supply system, the temperature that can be extracted from flue gas is activated into thermal source unit through R134A, makes heat supply
The water extraction that 10 DEG C~20 DEG C of return water temperature rises to 50 DEG C~60 DEG C, and two grades are carried to 120 DEG C using steam heat-exchanging temperature, are reached a high temperature
The heat supply purpose of water, makes power plant's heat capacity improve 4~5 times, substantial saving in the energy（Coal, water, electricity, work）, improve through
Ji efficiency, significantly reduces the discharge of greenhouse gases.All metal surfaces of whole system are handled using ceramics, have been reached anti-
Corruption, antiscour, raising equipment life, the effect of reduction entreprise cost.
