Mouth diameter.
The center of the spiral board is equipped with the fixed column through ventilation duct, welds between fixed column and the centre bore of spiral board
Connect fixation.
The excircle of the fixed column is equipped with the flooding nozzle of circumference uniform distribution.
The inner cavity of the ventilation duct is equipped with kick back, and kick back is equipped with the venthole that diameter is less than turbulence sphere, turbulent flow
Ball is in the cavity between kick back and spiral board.
The dust-extraction unit being combined using turbulent flow dust removing units, several turbulent flow dust removing units are highly longitudinal according to using
It enumerates, is laterally enumerated according to usable floor area, connect water pipe in the top fixed column for the turbulent flow dust removing units enumerated longitudinally in each, often
Root water pipe is connect with the backwash water pipe that top is arranged, and the bottom of each turbulent flow dust removing units laterally enumerated is landed in branch jointly
Grid is supportted, the spiral board air flue of the turbulent flow dust removing units of the grate opening and corresponding position of supportive grid communicates.
The turbulent flow dust removing units have hollow vortex chamber, are placed with multiple turbulence spheres in vortex chamber, flue gas stream is divided
Solution is at multiple small size tunnels, and into ball equipment is absorbed, flue gas forms circumferential stream, driving vortex chamber interior spheroid rotation by deflector
Turn, the flue dust absorbed in flue gas gathers and formed liquid film in spherome surface, to achieve the effect that dedusting.
Vertical fixed column is set in the cavity, plays the role of support to the turbulent flow dust removing units of longitudinal arrangement.
Flooding nozzle is set in the excircle of fixed column, turbulence sphere can be rinsed, make dust removing units can repeatedly
With.
It is equipped with kick back in the inner cavity of ventilation duct, the position of turbulence sphere fluctuating can be limited, while not hindering the stream of flue gas
It is logical.
Several turbulent flow dust removing units are combined, dust-extraction unit is formed, flue gas enters from lower part, top discharge, and
Top connection backwash water pipe, can be backwashed, to improve the bulk life time of equipment.
Detailed description of the invention
Fig. 1 is the partial enlarged view of turbulent flow dust removing units.
Fig. 2 is the overall structure diagram of dust-extraction unit.
Specific embodiment
As shown in Figure 1, a kind of turbulent flow dust removing units, intracavitary in ventilation duct 6 are equipped with spiral board 5, spiral shell is equipped in spiral board 5
Rotation type air flue, air flue one end are air inlet, and the air flue other end is gas outlet；In gas outlet, corresponding 6 lumen loading of ventilation duct is high
Degree is greater than several turbulence spheres 4 of 1/2 total height, and the diameter of turbulence sphere 4 is greater than gas outlet diameter.
The center of the spiral board 5 is equipped with the fixed column 3 through ventilation duct 6, the centre bore of fixed column 3 and spiral board 5
Between be welded and fixed.
The excircle of the fixed column 3 is equipped with the flooding nozzle 7 of circumference uniform distribution.
The inner cavity of the ventilation duct 6 is equipped with kick back 2, and kick back 2 is equipped with the venthole that diameter is less than turbulence sphere 4,
Turbulence sphere 4 is in the cavity between kick back 2 and spiral board 5.
As shown in Fig. 2, the dust-extraction unit that the turbulent flow dust removing units are combined, several turbulent flow dust removing units according to
It is longitudinally enumerated using height, is laterally enumerated according to usable floor area, fixed at the top for the turbulent flow dust removing units enumerated longitudinally in each
Column 3 connects water pipe, and every water pipe is connect with the backwash water pipe 1 that top is arranged, each turbulent flow dust removing units laterally enumerated
Bottom is landed in supportive grid 8,5 gas of spiral board of the turbulent flow dust removing units of the grate opening and corresponding position of supportive grid 8 jointly
Road communicates.
The dust-extraction unit that the turbulent flow dust removing units of the application are combined has the advantage that
1, depth dedusting: spherome surface forms liquid film, dust and moisture film contact and is captured, and can make to generate on sphere poly-
After the effects of inertial collision, adherency, agglutination occurs for collection, flue gas and sphere, dust and water and gas are made by sedimentation theory
Separation.As the water vapour that flue gas is carried secretly is constantly added, the dust of spherome surface attachment is rinsed, sphere is constantly updated
The liquid film on surface can drop back into spray column prime cement liquid pool from low power consuming, efficient absorption equipment.So circulation, finally realizes depth
Denitration dust collecting function；
2, improve desulphurization denitration efficiency of dust collection: the absorbing liquid in the flue gas risen in absorption tower entrainment of certain ingredients is divided
Solution enters dedusting demister, the flue gas driving vortex chamber interior spheroid rotation of rising, when passing through to flue gas at multiple small size tunnels
Dispersion can be generated and reintegrate the effect of gas field, significantly increase gas liquid interfacial area and time, gas liquid interfacial area increases
Add decades of times, low power consuming, efficient absorption equipment become denitration equipment, thus improve denitration efficiency；
3, non-scaling, do not block: efficient absorption ball equipment have self-cleaning function.When dust is adhered to spherome surface, meeting
Because the continuous motion collision of sphere, phase mutual friction and slide to thoroughly prevented fouling, blocking the problem of；
4, adaptable: influenced by exhaust gas volumn variation it is smaller, under 30-110% operating condition, system energy stable operation；
Installation is simple, short construction period.
