Description
Technical field
The utility model relates to flue gas ash removal fields, in particular to a kind of fume dust remover.
Background technique
Currently, flue gas ash removal mainly uses electric precipitator and sack cleaner.Wherein, electric precipitator is domestic and international coal-fired electricity
The most wide smoke and dust treatment equipment of application amount of standing, the coal unit in 80% or more China use electric precipitator.Electric precipitator has height
Efficiency, low energy consumption, it is easy to use and without secondary pollution the features such as, but there are high resistivity dust generate inverse corona, Gao Bi electricity
Resistance dust needs the common problem of the charged effect difference of reentrainment of dust caused by vibration dust-cleaning, fine dust, this is also that traditional electricity removes
Three technical bottlenecks existing for dirt device, for high specific resistance fine dust, i.e. the thinner high resistivity dust of granularity, traditional electricity removes
The dust collection efficiency of dirt device is extremely low.
For the above problem in the presence of the prior art, the new fume dust remover of one kind is provided and is of great significance.
Utility model content
To solve the above problems, the utility model provides a kind of fume dust remover, high resistivity dust can reduce
Specific resistance, increase the partial size of fine dust, to greatly improve the efficiency of dust collection of electric precipitator.
To achieve the above object, the fume dust remover of the utility model, including the flue for collecting flue gas, institute
It states and is successively arranged coalescer and electric precipitator on flue, the flue is connected with for conveying the defeated of flue gas conditioning agent
Pipeline is sent, one end of the conveyance conduit is connected with the holding vessel for storing flue gas conditioning agent, and the other end extends to the cigarette
In feed channel and it is equipped with the nozzle that flue gas conditioning agent is sprayed into the flue.
Preferably, the nozzle is located between the entrance and coalescer of the flue.
Preferably, the conveyance conduit is L-shaped.
Further, the injection direction of the nozzle is opposite with the flow direction of the flue gas.
Preferably, the nozzle is gas-liquid two-phase atomizer.
Preferably, the coalescer is integral type bipolar charge coalescer.
The fume dust remover of the utility model can be reduced high than electricity by spraying flue gas conditioning agent into flue
The specific resistance for hindering dust, improves the charging performance of dust, prevents the generation of back corona phenomenon, reduces reentrainment of dust；Meanwhile passing through
Coalescer is set, it is possible to increase the partial size of fine dust substantially increases the dedusting of electric precipitator in order to be trapped by electric precipitator
Efficiency, the especially efficiency of dust collection of high specific resistance fine dust.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the fume dust remover of the utility model, wherein solid arrow direction indicates flue gas
Flow direction, dotted arrow direction indicate the conveying direction of flue gas conditioning agent.
Specific embodiment
In the following, structure and working principle to the utility model etc. are further described in conjunction with attached drawing.
Referring to Fig. 1, the fume dust remover of the utility model can be used for trapping high specific resistance fine dust, which removes
Dirt device includes the flue 1 for collecting flue gas, is successively arranged coalescer 3 and electric precipitator 4, flue gas on flue 1
Pipeline 1 is connected with the conveyance conduit 5 for conveying flue gas conditioning agent, one end of conveyance conduit 5 with for storing flue gas conditioning agent
Holding vessel 2 be connected, the other end extends in flue 1 and is equipped with the nozzle for spraying flue gas conditioning agent into flue 1
6。
Specifically, nozzle 6 is located between the entrance 101 and coalescer 3 of flue 1, i.e. flue gas elder generation and flue gas conditioning agent
Coalescer 3 is entered back into after mixing.Flue gas conditioning agent in holding vessel 2 is delivered to nozzle 6 by conveyance conduit 5, is sprayed by nozzle 6
It comes into full contact with and mixes with the flue gas come in by the entrance 101 of flue 1 in flue 1, so that in flue gas and flue gas
Dust humidification, improves dust surface conductance, reduces the specific resistance of high resistivity dust, improve the charging performance of dust, on the one hand
It can prevent the dust layer of electric precipitator 4 from discharging, effectively control the generation of back corona phenomenon, improve the efficiency of dust collection of electric precipitator 4；
On the other hand, the adhesive force that can reduce dust, does not need to increase rapping intensity and just can effectively clear powder on 4 electrode of electric precipitator
Knoisphere reduces reentrainment of dust, further increases the efficiency of dust collection of electric precipitator 4.
In order to make flue gas conditioning agent and flue gas come into full contact with mixing, above-mentioned conveyance conduit 5 is L-shaped, makes the injection side of nozzle 6
To consistent with the extending direction of flue 1, it is preferable that the injection direction of nozzle 6 and the flow direction of flue gas are on the contrary, make cigarette
Gas adjusting material is head-on contacted with flue gas, is more fully mixed, and the specific resistance quickly to adjust dust improves powder to ideal range
The charging performance of dirt.In order to mix flue gas conditioning agent and flue gas uniformly, said nozzle 6 may be selected to be gas-liquid two-phase atomization spray
Mouth.
Above-mentioned flue gas conditioning agent is the liquid that can reduce the specific resistance of dust, can choose for industry water, sulfuric acid,
NH3、Na2CO3Solution, NaCl solution or diethylamine aqueous solution etc..Wherein, for alkalescent dust, using the tune of strong acid adjusting material
Effect processed is relatively good.
Above-mentioned coalescer 3 is preferably integral type bipolar charge coalescer, flue gas after being sufficiently mixed with flue gas conditioning agent into
Enter coalescer 3, the partial size thickening of fine dust is made by bipolar charge, the powder in flue gas is then trapped by electric precipitator 4
Dirt, the flue gas after dedusting are discharged from the outlet of flue 1 102, and the setting of coalescer 3 effectively reduces the discharge of fine dust
Concentration.
The fume dust remover of the utility model can be reduced high than electricity by spraying flue gas conditioning agent into flue 1
The specific resistance for hindering dust, improves the charging performance of dust, prevents the generation of back corona phenomenon, reduces reentrainment of dust；Meanwhile passing through
Coalescer 3 is set, it is possible to increase the partial size of fine dust substantially increases electric precipitator 4 in order to be trapped by electric precipitator 4
Efficiency of dust collection, the especially efficiency of dust collection of high specific resistance fine dust.
More than, the only schematic description of the utility model, it will be recognized by those skilled in the art that practical without departing from this
On the basis of novel working principle, a variety of improvement can be made to the utility model, this belongs to the protection of the utility model
Range.
