Abstract
The utility model discloses a wet venturi granite dust removing apparatus. The outside of a cylindrical vertical venturi tube made of granite is sheathed with a circular sleeve barrel made of granite, and a set of combined granite cyclone accelerator is arranged on the outlet end of the lower part of a diffusion tube of the venturi tube. The lower part of the combined granite cyclone accelerator is supported by a plurality of supporting seats made of granite to form a water seal tank. Flue gas with dusty water drops which are congealed from the venturi tube is whirled and expedited by the combined granite cyclone accelerator. After the flue gas with dusty water drops is ejected in a tangential mode in the speed of 17 m/s to 22 m/s into the annular space between the sleeve barrel and the venturi tube and is separated in a centrifugal mode, the clean flue gas is led out from the upper part of the sleeve barrel in a tangential mode. The utility model has the advantages of small volume and high efficiency.
Description
The utility model belongs to wet type shaped Venturi dedusting equipment, is used for the flue gas that purified industrial boiler, stove, manufacture of cement, grain processing and railway steam vehicle igniting are emitted.
At present, usually the venturi granite water dust scrubber that adopts is by the external horizontal or vertical Venturi tube of gallet water curtain dust collector, and so as to realizing coalescence and the capture to smokeshade, this is higher a kind of of efficient in the present wet-scrubbing equipment.But shortcoming is to have only to connect a spout, and floor space and space are all bigger, especially in existing equipment is transformed, when adopting venturi water film deduster to replace original cyclone dust collectors, must enlarge occupied ground, even need the reconstruction factory building, increase construction investment because of the factory building height restriction.
The purpose of this utility model provides a kind of under the preceding topic that improves efficiency of dust collection, and the cancellation moisture film supplies water, and floor space and space are little, can replace the cleaner of cyclone dust collectors under the situation that does not enlarge occupation of land and transform plant.
The utility model is achieved in that a cylindrical sleeves with certain internal diameter is set outside cylindrical vertical Venturi tube, both form by numb barnacle system, fiber crops stone claims granite again, and annular space basal area between the two should satisfy the flue gas rate of climb between them in the scope of 3～5m/s.Flue gas enters the collapsible tube of Venturi tube by upper entrance, enters anemostat through trunnion, in the joint portion of collapsible tube and trunnion atomizer is installed.Be provided with one group of combined type fiber crops stone eddy flow accelerator at the anemostat lower part outlet place of Venturi tube, has the numb stone bearing support of suitable height by several, each vane of eddy flow accelerator is combined to form vortex shape convergent spout, so as to making the process coalescence that carries that gets off along Venturi tube become the flue gas of dust-laden water droplet to obtain eddy flow and acceleration, and remain in the flow rates of 17～22m/s, in the annular space between tangential directive Venturi tube in the ground that is evenly distributed simultaneously and the circular sleeve.The exhanst gas outlet of deduster is tangentially drawn from circular upper cartridge, and consistent with the rotation direction of eddy flow accelerator.Enter formation eddy flow in being forced to property of flue gas ground between Venturi tube and the circular sleeve, thereby the centrifugation in flue gas of dust-laden water droplet is come out, be attached on the inwall of circular sleeve, be combined into current, flow in the water seal tank of bottom along the circular sleeve inwall, when the dust-laden buck overflows in the water seal tank, just pass through slag-drip opening, climb over water seal board again and flow in the outside detritus tank, the flue gas after being purified Self-duster tangentially exports to enter in the atmosphere through air-introduced machine and chimney and goes.
Combined type eddy flow accelerator is by 4～8 numb stone vanes and be with the last disk of centre bore and the lower disc that the middle part is a tapered protrusion to form, for reaching the flow rates of spiral convergent spout outlet regulation, the gross area F of this outlet
XDetermine by following formula:
In the formula: F
X---the combined type eddy flow accelerator outlet gross area (m
2),
N---numb stone vane number,
C---combined type eddy flow accelerator outlet gap width (mm),
H---numb stone vane total height (mm),
Q
C---smoke treatment amount (m
3/ h),
V
C---spiral convergent ejiction opening place flue gas flow rate.
The utility model has the following advantages compared to existing technology:
1, adopt vertical tube-in-tube structure, floor space is little, and horizontal layout is convenient.
2, adopt eddy flow convergent spout, the outlet of circular sleeve upper tangential is identical with eddy flow accelerator rotation direction in addition, causes mandatory cyclonic action, and centrifugal separating effect is good, and detergent power is strong.
3, the gallet water curtain dust collector after the Venturi tube is a kind of dehydrator in the prior art, after using numb stone sleeve instead, spilling water groove and water supply part have been cancelled, reduced by about 1/3 water consumption, and reduced the height of deduster, during in order to the replacement cyclone dust collectors, can install in the original place, must not reconstruct factory building.
Fig. 1 is the utility model structural representation
Fig. 2 is the A-A profile of Fig. 1
Fig. 3 is the B-B profile of Fig. 1
Further narrate the utility model below in conjunction with accompanying drawing:
Referring to Fig. 1, ash-laden gas enters the collapsible tube of Venturi tube 1 from upper entrance 9, atomizer 10 is installed in joint portion at collapsible tube and trunnion, ash-laden gas carries out gas-liquid mixed through Venturi throat and water smoke, in collision through the grit and the water droplet at anemostat place, the coalescence process, dust-laden water droplet behind the coalescence, process is by last disk 4, the eddy flow accelerator that lower disc 6 and vane 5 are formed causes the eddy flow and the acceleration of flue gas, and carry out centrifugation in the annular space 3 that tangential directive circular sleeve 2 in the ground that is evenly distributed and Venturi tube 1 form, the dust-laden water droplet is attached on the inwall of circular sleeve 2, be combined into current, flow in the bottom water seal tank 12 along inwall, the dust-laden buck in the water seal tank 12 constantly increases, by slag-drip opening 14, the water seal board 13 that overflow again flows in the outside detritus tank.Clean flue gas after being cleaned is discharged by tangential outlet L1.Lower disc 6 is by numb stone bearing 8 supportings.
Referring to Fig. 2, the diameter phi with cylindrical space that the numb stone vane 5 of certain altitude is combined into is identical with the diameter of the anemostat port of export of the mesopore of last disk 4 and Venturi tube 1.The last camber line of the vortex shape convergent spout 7 that fiber crops stone vane 5 is combined into, that is, the following circular arc line of numb stone vane, the circular arc of the cylindrical space that is combined into numb stone vane 5 is tangent.The outlet gap C of vortex shape convergent spout 7 should meet the requirements.
Referring to Fig. 3, clean flue gas outlet 11 is generally rectangle, and its rotation direction is consistent with the rotation direction of combined type eddy flow accelerator, can make dextrorotation, can also make left-handed.
