Description
Technical field
The utility model belongs to coal-fired plant flue gas Treatment process field, more particularly to a kind of depth waste gas purification apparatus.
Background technology
The device of existing processing dust-laden exhaust gas uses the combination of spray column and associated exhaust processing unit, its purpose elder generation substantially
Processing dust carries out waste gas purification again, avoids dust from blocking clean unit.But have spray column treatment effect still undesirable, study carefully it
Reason is that the time that waste gas enters discharge is very short, can not be stopped for a long time in spray column；But if increase spray column
Height and processing unit quantity, the problem of cost being caused too high again.For this, we improve a kind of depth waste gas purification
Device.
Utility model content
To solve deficiency of the prior art, the purpose of this utility model is to provide a kind of depth waste gas purification apparatus, purport
Solving the problem of existing dust-laden exhaust gas treatment effect is undesirable, and equipment cost is too high.
To achieve the above object, the technical solution of the utility model is：A kind of depth waste gas purification apparatus, including spray
Tower, the spray tower bottom are provided with oxidation pond；Turbulator is provided with below the spray system of the spray column；The turbulator is
Center drilling, and turbulator edge and spray column inner wall sealing；The chimney intake of the spray column is located at below turbulator, and cigarette
Road import helically type and tangent with spray tower wall, and is provided with cooling spray system at chimney intake；Above the spray system
It is additionally provided with packing layer；Straight-line chimney is installed at the top of the spray column, flue demister is provided with chimney.
Preferably, the cooling spray system is clear water spray system, and cooling spray system 6 sprays coverage rate not
Less than 100%.
Preferably, being provided with drop removing system above the spray system of the spray column, set above drop removing system
There is wet electrical dust precipitator.
Preferably, the drop removing system is 2~3 layers of ridge type or Flat defroster.
Hold liquid layer preferably, having above the turbulator, and turbulator be percent opening be 30%~40%, aperture
For 2205 or 2507 thick alloy discs of 25mm~35mm, 2~3mm.
The beneficial effects of the utility model：Reaction time is abundant, high treating effect, and equipment cost is relatively low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, a kind of depth waste gas purification apparatus, including spray column 1, the bottom of spray column 1 are provided with oxidation pond
2；The lower section of spray system 3 of the spray column 1 is provided with turbulator 4；Perforate centered on the turbulator 4, and the edge of turbulator 4
With the inner wall sealing of spray column 1；The chimney intake 5 of the spray column 1 is located at the lower section of turbulator 4, and helically type is simultaneously for chimney intake 5
It is tangent with the wall of spray column 1, and cooling spray system 6 is provided with chimney intake 5；The top of spray system 3 is additionally provided with packing layer
7；The top of spray column 1 is provided with straight-line chimney 8, and flue demister 9 is provided with chimney 8.
The cooling spray system 6 is clear water spray system, and cooling spray system 6 sprays coverage rate not less than 100%；
The top of spray system 6 of the spray column 1 is provided with drop removing system 10, and the top of drop removing system 10 is removed provided with wet type electricity
Dirt device 11；The drop removing system 10 is 2~3 layers of ridge type or Flat defroster；The top of turbulator 4, which has, holds
Liquid layer, and turbulator 4 is 2205 or 2507 alloys that percent opening is 30%~40%, aperture is 25mm~35mm, 2~3mm is thick
Disk.
It is pre- that chimney intake 5 entrance spray column 1 of the former flue gas through screw type and process cooling spray system 6 carry out cooling dedusting
Processing, the reduction of flue-gas temperature can reduce the volume flow of flue gas, increase residence time of the flue gas in spray column 1, simultaneously
The mode of spiral air intake further ensures residence time of the flue gas in spray column 1, and the spray liquid of spray system 6 falls into turbulator
4, the particulate matter and sulfur dioxide carried in turbulator semi-finals gas-liquid contact mass transfer removing flue gas, spray liquid are advanced on flue gas
Enter oxidation pond 1 after strengthening absorbing particles thing and sulfur dioxide；Flue gas continuation is up inversely to be connect with the spray liquid of spray system 6
Touch and fully absorb sulfur dioxide entrained in flue gas；Subsequently enter drop removing system 10, the stone that efficient removal flue gas carries
Cream drop, while promote growing up for fine particle, the flue gas after drop removing system 10 is handled enters wet electrical dust precipitator 11,
The particulate matters such as the condensable such as deep removal fine particle, SO3 particulate matter, droplet；Flue gas is up by the deep purifying of packing layer 7
Reason, while packing layer 7 hinders flue gas speed uplink, increases its residence time；Flue gas continue on flue demister 9 of passing through remove depth
It is discharged into after the particulate matter that degree removing flue gas carries droplet and condensation is grown up from chimney 8 in external environment；The oxidation pond 2 will
It is that gypsum slurries enter follow-up processing system processing that slurries, which are carried out fully oxidized,.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent substitution or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
