Description
Technical field
The invention belongs to smoke treated field, and in particular to a kind of flue spray dust remover.
Background technology
With industrial expansion, energy input gradually rises, and the discharge capacity of atmosphere pollution increases.Air quality is environment matter
How one important indicator of amount, remove the important goal that the dust floated in air is environmental improvement.The flue gas of boiler discharge
In contain substantial amounts of dirt, traditional dust collection method carries out dedusting for high-temperature flue gas are directly entered deduster, although high temperature fume dust removal
Method also have many, including bag-type dusting, electrostatic precipitation and method etc. electric precipitation.But these methods are due to deduster dedusting
Limited in one's ability, the flue gas ash removal effect after dedusting is unsatisfactory, and dust collection method is complicated, cleaner high cost.
The content of the invention
The present invention provides a kind of flue spray dust remover to solve Problems Existing, increases the spraying of deduster previous stage and removes
Dirt equipment, by lye tank for one-level spray for dust suppression provides alkali lye, is provided with multiple spray heads inside one-level aerosolater, utilize
The operation principle of spray dust, a large amount of dusts in raw flue gas are collected, and the purpose of dust content in flue gas is reduced so as to reach,
Flue-gas temperature can be simultaneously reduced in addition, so as to reduce exhaust gas volumn after demister, can reduce the load of deduster and air-introduced machine, reach
The purpose of optimization deduster dust removing effects and reduction station-service electric load is significant to energy-conserving and environment-protective.
What the present invention was achieved through the following technical solutions：
A kind of flue spray dust remover, including：It is boiler, lye tank, one-level aerosolater, deduster, air-introduced machine, de-
Sulphur tower and chimney, wherein：The boiler connects one-level aerosolater by flue, and one-level aerosolater top is provided with point
With main pipe, the multiple atomizers of distribution main pipe connection, the atomizer connects spray head, the one-level aerosolater
Bottom is provided with delivery port, and the one-level aerosolater connects deduster by flue, and the deduster connects air-introduced machine, described to draw
Blower fan connects desulfurizing tower, and the desulfurizing tower connects chimney, MOD, the lye tank are provided between the desulfurizing tower and chimney
Alkali lye water inlet pipe is connected by alkali lye outlet pipe I, the alkali lye water inlet pipe connects the distribution main pipe of one-level aerosolater,
Parallel connection is provided with alkali lye outlet pipe II and alkali lye outlet pipe III on the alkali lye outlet pipe I.
Multiple spray head erects in the one-level aerosolater are arranged in parallel.
Thermometer is installed at the outlet flue of the one-level aerosolater, the flue gas after temperature control spray for dust suppression
Temperature is more than 130 DEG C, it is ensured that the temperature that flue gas enters deduster below is higher than acid dew point.
On the alkali lye water inlet pipe control valve group II and control valve group I, institute are sequentially provided with along alkali lye flow direction
State control valve group I and be parallel with control valve.
Check-valves and force (forcing) pump are equipped with the alkali lye outlet pipe II and alkali lye outlet pipe III, the check-valves is along alkali lye
Flow direction is arranged on before force (forcing) pump.
Alkali lye is operationally delivered to one-level aerosolater water inlet and enters one by the present invention by the adjusted valve of force (forcing) pump
Level aerosolater, high pressure alkali lye sprays through the atomization that one-level aerosolater distribution main pipe is distributed to one-level aerosolater
Mouth, the water mists of atomization enter flue and are mixed with heat smoke by spray head ejection, to flue gas cool-down, while with the dirt in flue gas
Grain is the nuclei of condensation, condenses into the thin dirt in big water droplet aggregation flue gas, ultimately forms the sludge pellet of bulky grain, and the flue dust of bulky grain is with cigarette
The deduster that gas enters below carries out dedusting collection, and the smog after final dedusting is discharged by chimney.
Beneficial effects of the present invention are：
(1) it is of the invention in original deduster previous stage aerosolater, by lye tank for one-level spray for dust suppression is provided
Alkali lye, is provided with multiple spray heads inside one-level aerosolater, using the operation principle of spray dust, will be big in raw flue gas
Amount dust is collected, and the purpose of dust content in flue gas is reduced so as to reach.
(2) because the spray of alkali lye reduces the temperature of flue gas, so as to reduce exhaust gas volumn after demister, deduster can be reduced
And the load of air-introduced machine, reach optimization deduster dust removing effects and reduce the purpose of station-service electric load, to energy-conserving and environment-protective meaning weight
Greatly.
