Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Combination chord of contact dedusting day with fog as shown in Figure 3, described dedusting day with fog comprises dust removal mist device, motor 7, motor support ring 8, water leg 9, draining valve 10, catch net 11, connecting axle 6 afterbody one end in described dust removal mist device is connected with motor 7 by bearing, connecting axle 6 afterbody one end is one end of lower wind direction, motor 7 is installed one end on the leeward and is conducive to reducing resistance, improves motor service life.
Described motor 7 is fixed on motor support ring 8, motor support ring 8 is fixed in cylindrical shell, the cylindrical shell that the lower end of dust removal mist device keeps at a certain distance away is provided with water leg 9, cylindrical shell outside is provided with the draining valve 10 corresponding with water leg 9, described catch net 11 is fixed on from the cylindrical shell of the upwind of dust removal mist device, catch net 11 Main Function is tackled by the bulk object in gas in advance, and catch net 11 can adopt nylon yarn to be made.
Dust removal mist device as shown in Figure 1, a kind of combination chord of contact dust removal mist device, comprises wheel disc 4 and lower wheel disc 3, two wheel discs are parallel to each other, distance between wheel disc is 100 ~ 300mm, and wheel disc is integrally formed by connecting axle 6, and motor 7 is connected with dust removal mist device axle 6 by rotating shaft.
The second vertical chord of contact 2 that many uprush flow to is evenly distributed with in described lower wheel disc 3; The first vertical chord of contact 1 that many uprush flow to is evenly distributed with in described upper wheel disc 4; Flange connector 12 is established in described connecting axle 6 upper end, and flange connector 13 is set in connecting axle 6 bottom; First vertical chord of contact 1 is connected between flange connector 12 and upper wheel disc 4 wheel rim; Second vertical chord of contact 2 is connected between lower flange connector 13 and lower wheel disc 3 wheel rim.Vertical chord of contact is uniformly distributed the fan-shaped interception face forming divergent shape in wheel disc;
Many oblique chord of contacts 5 crossing with air flow direction oblique line are provided with between two described wheel discs; Between the upper flange connector 12 that oblique chord of contact 5 is wrapped in the upper wheel disc 4 of connection and the wheel hub edge of lower wheel disc 3, be uniformly distributed between upper wheel disc 4 and lower wheel disc 3 and form positive taper type.
The dust removal mist parts of contrast shown in Fig. 2, the first projection 1-1 of vertical chord of contact 1 on lower wheel disc 3 wherein going up wheel disc 4 does not overlap with the adjacent second perpendicular chord of contact 2 of lower wheel disc 3; Lower wheel disc 3 angle coiled between interior adjacent second perpendicular chord of contact 2 is 3 ~ 4 °, and the angle that upper wheel disc 4 coils between the interior adjacent first vertical chord of contact 1 is 2 ~ 3 °, and the vertical chord of contact quantity in upper wheel disc 4 is more than the vertical chord of contact quantity of lower wheel disc 3.
The Angle ambiguity of vertical chord of contact is at 2 ~ 3 ° or 3 ~ 4 °, one is to ensure higher collecting effect, be the resistance not increasing gas flowing under the prerequisite ensureing collecting efficiency on the other hand, improve the percent of pass of dust-laden fog body, reduce the rotary resistance of motor.
Go up the vertical chord of contact of vertical chord of contact more than lower wheel disc 3 of wheel disc 4 in addition, second vertical the sparse of chord of contact 2 setting of lower wheel disc 3 is to allow dust-laden fog physical efficiency flow fast through, after second vertical chord of contact 2 removes part dust and droplet, by the more intensive first vertical chord of contact 1, first vertical chord of contact 1 can tackle a part for dust-laden fog body not easily collecting, meanwhile, because most of dust, droplet are got rid of in dust-laden fog body, the intensive first vertical chord of contact 1 can not hinder gas to flow through.
One end of the projection of oblique chord of contact 5 on lower wheel disc 3 flange connector 13 on the lower overlaps with lower flange connector 13 tie point with corresponding second vertical chord of contact 2, and the projection other end of described oblique chord of contact 5 overlaps with the wheel rim tie point of lower wheel disc 3 with the adjacent second vertical chord of contact 2; The projection of oblique chord of contact 5 on upper wheel disc 4 is crossing with adjacent two the first vertical chord of contacts 1; Neighboring vertical chord of contact in the projection in vertical direction of oblique chord of contact 5 and upper and lower wheel disc forms " Z " font.Oblique chord of contact 5 is interspersed with vertical chord of contact and increases footprint, is conducive to the trapping strengthened the droplet in gas and dust, improves the collecting effect of dust removal mist device.
The diameter of the vertical chord of contact 2 of the first vertical chord of contact 1, second, oblique chord of contact 5 is 0.2 ~ 1mm, and chord of contact can be drawn by corrosion resistant metal bar and form, as nickel-cadmium, stainless steel, titanium alloy etc.Also the high macromolecular material of corrosion-resistant tensile strength can be used to be made, and such as use nylon yarn, glass fibre, polytetrafluoroethylene fibre, polyster fibre etc. to produce chord of contact, the chord of contact of coiling has certain pre-tensioning.The interception face of described oblique and vertical chord of contact composition can be formed by a complete filament winding, also can be wound around by the combination of multi-filament string.
Lower wheel disc 3, upper wheel disc 4 and connecting axle 6 all use resistant material to make, and not corrosion resistant metal material also can be used to make, and anticorrosive is coated on surface, as epoxy resin.
The course of work: described combination chord of contact dedusting day with fog is arranged in columnar gas flow.Start the motor 7 of dedusting day with fog, motor 7 drives takes turns disc spins up and down.Dust-laden fog body flows to upper wheel disc 4 from lower wheel disc 3, in order to make the easier sedimentation of the powder in gas, a sprayer unit can be set at the upwind place of runner, make dust in gas become moistening and be easy to sedimentation, interception through catch net 11 is removed a part of agglomerate body material, when flowing through lower wheel disc 3, dust-laden fog stream is cut by the atwirl second vertical chord of contact 2, very large relative velocity is there is in the dust now in air-flow with droplet chord of contact 2 vertical with second, droplet or wet dust are because filtering, interception, collision effect is dammed on the second vertical chord of contact 2, descend the rotating band moving air flow of wheel disc 3 to rotate simultaneously, large drop in gas and bulk dust get rid of under the influence of centrifugal force to cylinder inboard wall with it collision rift rest on barrel.
The the second vertical chord of contact 2 rotated can vibrate under the percussion of air-flow, and the chord of contact of vibration makes fine mist or wet dust become large, is conducive to the collection of these drops or wet dust.
Dust-laden fog stream is when flowing through lower wheel disc 3 and upper wheel disc 4 is middle, and air-flow is caused air-flow to produce violent disturbance by the oblique cutting of oblique chord of contact 5 forming strong turbulent flow, droplet and wet dust are collided with each other, it is separated subsequently to condense.It is identical with the action principle of droplet that dust removed by upper wheel disc 4 and lower wheel disc 3.The dust separated and droplet are slowly slipped in the dust collecting trough 9 of bottom on cylindrical shell, open water discharging valve 10 and can be discharged.
It is high that the present invention has percent of pass, interception dust and the effective advantage of droplet, the chord of contact dust removal mist of rotating is utilized to avoid the problem of raising the efficiency by the parallel superposition of sandwich construction, adopt the mode at interval between string, solve the problem that existing machinery dedusting day with fog resistance is too large, achieve the object improving capture rate, simplify modular structure.
