Description
Technical field：
The present invention relates to one kind atomization compression flue-gas denitrification heat-energy recovering apparatus and denitrogenation and heat energy recovering method.
Background technology：
Contain substantial amounts of nitrogen oxides and water vapour in the flue gas discharged in boiler combustion process, flue gas is directly discharged
Severe contamination can be caused after in air to environment, is produced " haze ", while the heat in flue gas is also wasted.
The content of the invention：
It is an object of the invention to provide one kind atomization compression flue-gas denitrification heat-energy recovering apparatus and denitrogenation and energy recovery side
Method.
Above-mentioned purpose is realized by following technical scheme：
One kind atomization compression flue-gas denitrification heat-energy recovering apparatus, its composition includes：One group of gas fired-boiler, the combustion described in a group
Gas boiler is connected by flue with atomization compression set one end, and described atomization compression set is described built with atomizer
Atomizer be connected with denitration liquid pool by pipeline, on described pipeline be equipped with variable frequency pump, on described atomization compression set
Equipped with one group of condensed water discharge outlet, described condensed water discharge outlet is connected by pipeline and condensation water tank, described atomization compression
The device other end is connected by pipeline and axial flow blower.
The denitrogenation of described atomization compression flue-gas denitrification heat-energy recovering apparatus and heat energy recovering method, it is characterized in that：Combustion gas
The flue gas of boiler discharge is admitted to atomization compression set by flue, atomizer and denitration liquid pool in atomization compression set
Loop is formed, denitration liquid pool constantly provides denitration liquid to atomizer in the presence of variable frequency pump, by the atomization of atomizer, mist
Denitration liquid fog after change is sufficiently mixed with flue gas, and nitrogen oxides molecule is caught and reacted by denitration fog in mixed process, so
Liquefied substance is condensed into together afterwards, by pipeline inflow condensate tank；The heat in flue gas also can be by harmful smoke simultaneously
Condensed with the long range of denitration liquid fog and reclaimed.
Beneficial effect：
1. the flue gas that the present invention discharges gas fired-boiler is admitted to atomization compression set, atomization compression by flue
The atomizer that device is installed forms loop with denitration liquid pool, and denitration liquid pool is constantly provided to atomizer in the presence of variable frequency pump
Denitration liquid, by the atomization of atomizer, the denitration liquid fog after atomization is sufficiently mixed with flue gas, and denitration fog will in mixed process
Nitrogen oxides molecule is caught and reacts, and liquefied substance is then condensed into together, by pipeline inflow condensate tank；Simultaneously in flue gas
Heat can also be condensed by the long range of harmful smoke and denitration liquid fog and reclaimed.
The present invention enables to harmful smoke and denitration liquid fog fully to react, can efficiently by the nitrogen oxidation in flue gas
Thing and the extremely large amount of removal of water vapour, make boiler emission reach discharging standards, reduce " haze ", while the heat in flue gas
Also can be condensed by the long range of harmful smoke and denitration liquid fog and more reclaimed.
