Abstract
Disclosed is a boiler flue gas desulfurization and denitrification device. The boiler flue gas desulfurization and denitrification device comprises a coal-fired boiler, a bag-type dust remover, a desulfurizing tower air inlet, a desulfurizing tower, a dehumidification purification tower, a fan and a chimney. The boiler flue gas desulfurization and denitrification device is characterized in that the coal-fired boiler is sequentially connected with the bag-type dust remover, the desulfurizing tower air inlet, the desulfurizing tower, the dehumidification purification tower, the fan and the chimney, an ammonium hydroxide injection opening is formed above the side wall of the hearth of the coal-fired boiler, a sprinkler pipe is arranged at the upper portion of the desulfurizing tower air inlet, a flue gas outlet is formed in the upper portion of the sprinkler pipe, the flue gas outlet is connected with the dehumidification purification tower, the sprinkler pipe is connected with a desulfurizing pump, and the desulfurizing pump is connected with a calcium hydroxide storage tank. The boiler flue gas desulfurization and denitrification device has the advantages that the desulfurizing and denitrifying efficiency is high, up-to-standard release of flue gas is achieved, and environmental pollution is avoided.
Description
Technical field
The present invention relates to boiler flue gas desulfurization denitrification apparatus, be particularly used for what purification coal-burning boiler produced
Flue gas, belongs to environmental technology field.
Background technology
At present, containing sulfur in the coal dust used by coal-burning boiler, through 1200 DEG C～1500 DEG C of high-temperature firing processes
In, the sulfur in raw material generates SO through chemical reaction2Enter flue gas, fire coal boiler fume SO2Concentration of emission reach
To 5000～6000mg/Nm3, environment is caused severe contamination.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that boiler flue gas desulfurization denitrification apparatus, denitrification efficiency is high, makes
Flue gas qualified discharge, it is to avoid to environment.
The technical scheme is that boiler flue gas desulfurization denitrification apparatus, including coal-burning boiler, bag-type dust
Device, desulfurizing tower air intake, desulfurizing tower, dehumidifying purifying column, blower fan, chimney, it is characterised in that: described combustion
Coal burning boiler is linked in sequence sack cleaner, desulfurizing tower air intake, desulfurizing tower, dehumidifying purifying column, blower fan, cigarette
Chimney, the sidewall of described coal-burning boiler burner hearth is arranged over ammonia entrance, and desulfurizing tower air intake top is provided with
Shower, shower top is provided with exhanst gas outlet, and exhanst gas outlet connects dehumidifying purifying column, and shower is with de-

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention is boiler flue gas desulfurization denitrification apparatus, including coal-burning boiler 1, bag-type dust
Device 2, desulfurizing tower air intake 3, desulfurizing tower 4, dehumidifying purifying column 7, blower fan 8, chimney 9, it is characterised in that:
Described coal-burning boiler 1 be linked in sequence sack cleaner 2, desulfurizing tower air intake 3, desulfurizing tower 4, dehumidifying purify
Tower 7, blower fan 8, chimney 9, the sidewall of described coal-burning boiler 1 burner hearth is arranged over ammonia entrance 12, de-
Sulfur tower air intake 3 top is provided with shower 6, and shower 6 top is provided with exhanst gas outlet 5, exhanst gas outlet
5 connect dehumidifying purifying columns 7, and shower 6 is connected with desulfurization pump 10, desulfurization pump 10 and calcium hydroxide storage tank
11 connect.
Use Ca (OH)2As desulfurization absorbent, desulfurizing agent is squeezed into desulfurizing tower 4 and flue gas through desulfurization pump 10
It is fully contacted, makes the sulfur dioxide in flue gas and desulfurizing agent Ca (OH)2Carry out reaction and generate CaSO4, make flue gas
Qualified discharge, it is to avoid to environment；
Ammonia is sent into ammonia entrance 12 by ammonia water spray pipe and is entered in coal-burning boiler 1 burner hearth, at coal-fired pot
In stove 1 burner hearth, the nitrogen oxides generation chemical reaction in ammonia and flue gas, reach the nitrogen oxides in flue gas
Removing.
Apparatus of the present invention denitrification efficiency is high, makes flue gas qualified discharge, it is to avoid to environment.
