Description

A kind of flue spray dust remover
Technical field
The utility model 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, the discharge capacity increase of atmosphere pollution.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 removal method be high-temperature flue gas be directly entered deduster carry out dedusting, although high temperature fume dust removal Method also have the methods such as many, including bag-type dusting, electrostatic precipitation and 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 removal method is complicated, and cleaner cost is high.
The content of the invention
The utility model provides a kind of flue spray dust remover, the previous stage spray of increase deduster to solve Problems Existing Mist cleaner, is provided for one-level spray for dust suppression by lye tank and multiple spray heads is provided with inside alkali lye, one-level aerosolater, Using the operation principle of spray dust, a large amount of dusts in raw flue gas are collected, so as to reach dust content in reduction flue gas Purpose, flue-gas temperature can be reduced simultaneously in addition, so as to reduce exhaust gas volumn after demister, can reduce the negative of deduster and air-introduced machine Lotus, reaches the purpose of optimization deduster dust removing effects and reduction station-service electric load, significant to energy-conserving and environment-protective.
What the utility model 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 is connected to be provided with the top of one-level aerosolater, the one-level aerosolater by flue to be divided With main pipe, the distribution main pipe connects multiple atomizers, and 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, and 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, It is in parallel on the alkali lye outlet pipe I to be provided with alkali lye outlet pipe II and alkali lye outlet pipe III.
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, passes through 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.
It is equipped with check-valves and force (forcing) pump on 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 by the adjusted valve of force (forcing) pump and entered by the utility model Enter one-level aerosolater, high pressure alkali lye is distributed to the mist at the top of one-level aerosolater through one-level aerosolater distribution main pipe Change nozzle, the water mists of atomization enter flue and mixed by spray head ejection with heat smoke, to flue gas cool-down, while with flue gas Dirt particle 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, the flue dust of bulky grain The deduster entered below with flue gas carries out dedusting collection, and the smog after final dedusting is discharged by chimney.
The beneficial effects of the utility model are:
(1) the utility model, in original deduster previous stage aerosolater, is one-level spray for dust suppression by lye tank There is provided and multiple spray heads are provided with inside alkali lye, one-level aerosolater, using the operation principle of spray dust, by raw flue gas A large amount of dusts collect so that reach reduction flue gas in dust content purpose.
(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, the purpose of optimization deduster dust removing effects and reduction station-service electric load is reached, to energy-conserving and environment-protective meaning weight Greatly.
