The catalytic performance of agent, NOx and dilution ammonia occur catalytic reduction reaction and generate N in flue gas2, the desulfurization for realizing flue gas is de-
Nitre, the carbon base catalyst after adsoption catalysis reaction recycle after being regenerated.Dilution ammonia is injected in desulfuring and denitrifying apparatus, is used
It is N by the NOx conversion in flue gas in the denitration reaction for realizing gas cleaning process2。
Flue gas system is the core of carbon base catalyst flue gas desulfurization and denitrification technology, and flue gas is introduced desulfurization by booster fan
Denitrating tower is discharged into atmosphere by chimney after gas cleaning.
Summary of the invention
In order to solve the problems in the existing technology the present invention, provides the charcoal of a kind of adjustable flue gas flow and temperature
The flue gas system of base catalytic desulfurizing denitrification apparatus.
In order to achieve the above object, technical solution proposed by the present invention are as follows: a kind of charcoal base catalytic desulfurizing denitrification apparatus
Flue gas system, including desulphurization denitration tower and chimney, desulphurization denitration tower inlet are equipped with gas approach, and exit is equipped with outlet cigarette
Road, exhaust pass are connect with chimney, and the gas approach is equipped with booster fan, and gas approach is connected with cold before booster fan
Wind intake line, is equipped with the first electric gear plate valve before cold wind intake line, and cold wind intake line end is equipped with air filtration
Device, cold wind intake line are equipped with the second electric gear plate valve after air filter.
Be further designed to above-mentioned technical proposal: the gas approach is between booster fan and cold wind intake line
Equipped with flowmeter, gas approach is equipped with thermometer between booster fan and desulphurization denitration tower.
The gas approach between booster fan and flowmeter be equipped with pressure transmitter, gas approach booster fan with
Third electric gear plate valve is equipped between pressure transmitter.
The gas approach is equipped with the first flue gas analyzer between booster fan and thermometer, and exhaust pass is equipped with the
Two flue gas analyzers.
The 4th electric gear plate valve and the 5th electric gear plate valve are respectively equipped at the entrance and exit of the desulphurization denitration tower.
The invention has the benefit that
The inlet flow rate of booster fan is detected in the present invention by flowmeter, thermometer detects the flue gas temperature of booster fan outlet
Degree, and be the aperture according to the second electric gear plate valve for adjusting cold wind intake line with the two parameters, enter to realize to adjust
The flue gas flow and temperature of desulphurization denitration tower.
When the flue gas flow of booster fan entrance is lower than setting value, the aperture for adjusting the second electric gear plate valve supplements air
Improve flue gas flow.When the temperature of booster fan outlet is higher than setting value, the aperture supplement for adjusting the second electric gear plate valve is cold
Air reduces flue-gas temperature.When the two requires sucking air simultaneously, the amplitude of accommodation of the second electric gear plate valve preferentially executes larger
Opening value.
During adjusting flue gas flow and temperature, by the inlet pressure of pressure transmitter measurement booster fan, come
The aperture of third electric gear plate valve is adjusted, realizes the steady of flue pressure.
