Abstract
The utility model relates to a wet-type dust catcher, in particular to a venturi dust catcher for a filter material layer. The venturi dust catcher comprises a venturi tube and a dedusting cylinder, wherein the bottom of the venturi tube is communicated with the bottom of the dedusting cylinder at the lower position; the top of the venturi tube is provided with an air inlet connection tube; and the surface of the venturi tube on the lower side of the air inlet connection tube is communicated with a water inlet connection tube. The venturi dust catcher is characterized in that: filter screens are arranged on the middle part and the top of the dedusting cylinder, and filter materials are put into the dedusting cylinder between the two filter screens; a water seal overflow device is arranged at the bottom of the dedusting cylinder; a centrifugal fan is arranged on the top of a conical platform of the dedusting cylinder; a motor is arranged on the upper side of the centrifugal fan; and an air exhaust connection tube is connected to the side part of the centrifugal fan. Therefore, the venturi dust catcher is reasonable in design and has a good dirt removal effect.
Description
(1) technical field
The utility model relates to a kind of wet scrubber, particularly a kind of venturi filter material layer deduster.
(2) background technology
Disperse the operating environment that the locus is limited, traditional venturi scrubber of coal preparation plant's employing at present seeing that the local dirt of colliery coal preparation plant production system source is numerous; Constitute by Venturi tube and dedusting cylinder two big parts; And guiding eddy flow plate and centrifugal blower fan blade wheel are only arranged in the dedusting cylinder, and centrifugal blower is positioned at the dedusting cylinder and causes drum diameter big, and cost is high; Problems such as efficient is lower, and water consumption is big.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, a kind of good dedusting effect, power consumption be provided at the bottom of, practice thrift the venturi filter material layer deduster of operating cost.
The utility model is realized through following technical scheme:
A kind of venturi filter material layer deduster; Comprise Venturi tube, dedusting cylinder; The Venturi tube bottom is connected with the dedusting cylinder bottom in downstream, and the Venturi tube top is that air intake is taken over, and air intake is taken over downside Venturi tube surface and is communicated with into water adapter; It is characterized in that: middle part and top are respectively arranged with filter screen in the said dedusting cylinder, are placed with filtrate in the dedusting cylinder between two filter screens; Said dedusting cylinder bottom is equipped with the water seal overflow pipe; Said dedusting cylinder taper platform top is equipped with centrifugal blower, and the centrifugal blower upside is equipped with motor; Said centrifugal blower sidepiece is connected with air draft and takes over.
The optimal case of the utility model is:
Said centrifugal blower is horizontal centrifugal blower, and motor is a vertical machine; Said water inlet is equipped with ball valve in taking over, and water inlet is taken in the tail end Venturi tube atomizer is installed; Said centrifugal blower sidepiece has manhole; Be provided with filtrate between said dedusting drum surface two filter screens and add the hole, dedusting drum surface lower screen downside is provided with manhole; Said filtrate is a pvc multiaspect hollow ball.
The beneficial effect of the utility model is: the venturi filtrate deduster of this utility model is simple in structure, reasonable in design; Centrifugal blower independently places on the dedusting cylinder top; The performance of centrifugal blower can be fully guaranteed, and allocating power has reduced by 1/2 on year-on-year basis thus, and dedusting drum diameter has dwindled 1/4 on year-on-year basis; Deduster suction increases, and practices thrift cost; Under the blower fan suction function, dust suction, spraying utilize Venturi tube mechanism characteristics, and dust contacts with water smoke closely; Fully harmonious in water smoke, air-flow gets into the cylinder eddy flow with tangent line, along with air velocity reduces suddenly, at the bottom of the dust that particle is big, heavy falls into earlier tin; Discharge with water, all the other dust cut and catch through collision, the absorption of filter material layer, realize dedusting, dewater, the effect of demist; Sewage enters water treatment system with water pipe, is colourless clean air and exhaust duct is discharged, qualified discharge.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the main TV structure sketch map of the utility model;
Accompanying drawing 2 is the plan structure sketch map of the utility model;
Among the figure, 1 centrifugal blower, 2 motors, 3 dedusting cylinders, 4 filtrates, 5 filter screens, 6 Venturi tubes, 7 air intakes are taken over, and 8 air drafts are taken over, and 9 water inlets are taken over, 10 ball valves, 11 atomizers, 12 water seal overflow devices, 13 manholes, 14 filtrates add the hole.
(5) specific embodiment
