The specific embodiment
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 dedusting day with fog part, motor 7, motor support ring 8, water leg 9, draining valve 10, catch net 11, connecting axle 6 afterbody one end in described dedusting day with fog part are connected with motor 7 by bearing, connecting axle 6 afterbody one end are one end of lower wind direction, motor 7 is installed one end on the leeward and is conducive to reduce 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 dedusting day with fog part keeps at a certain distance away is provided with water leg 9, cylindrical shell outside is provided with the draining valve corresponding with water leg 9 10, described catch net 11 is fixed on the cylindrical shell of the upwind of dedusting day with fog part, catch net 11 Main Functions are in advance the bulk object in gas to be tackled, and catch net 11 can adopt nylon yarn to be made.
Dedusting day with fog part as shown in Figure 1, a kind of combination chord of contact dedusting day with fog part, 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 dedusting day with fog part axle 6 by rotating shaft.
In described lower wheel disc 3, be evenly distributed with the second vertical chord of contact 2 that many uprush flow to; In described upper wheel disc 4, be evenly distributed with the first vertical chord of contact 1 that many uprush flow to; Flange connector 12 is established in described connecting axle 6 upper ends, and flange connector 13 is set in connecting axle 6 bottoms; The first vertical chord of contact 1 is connected between flange connector 12 and upper wheel disc 4 wheel rims; The second vertical chord of contact 2 is connected between lower flange connector 13 and lower wheel disc 3 wheel rims.Vertical chord of contact is uniformly distributed the fan-shaped interception face that forms divergent shape in wheel disc;
Between two described wheel discs, be provided with the many oblique chord of contacts 5 crossing with air flow direction oblique line; Oblique chord of contact 5 is wrapped in and connects between the upper upper flange connector 12 of wheel disc 4 and the wheel hub rim of lower wheel disc 3, is uniformly distributed and forms positive taper type between upper wheel disc 4 and lower wheel disc 3.
Contrast shown in Fig. 2 except cloud parts, the first projection 1-1 of vertical chord of contact 1 on lower wheel disc 3 that wherein goes up wheel disc 4 do not overlap with the adjacent second vertical chord of contact 2 of lower wheel disc 3; Angle in lower wheel disc 3 dishes between the adjacent second vertical chord of contact 2 is 3～4 °, and the angle in upper wheel disc 4 dishes between the 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 of vertical chord of contact is controlled at 2～3 ° or 3～4 °, the one, in order to guarantee higher collecting effect, be the resistance that does not increase gas flow under the prerequisite that guarantees collecting efficiency on the other hand, improve the percent of pass of dust-laden fog body, the rotary resistance of reduction motor.
Go up in addition the vertical chord of contact of wheel disc 4 more than the vertical chord of contact of lower wheel disc 3, it is sparse that the second vertical chord of contact 2 of lower wheel disc 3 arranges is in order to allow dust-laden fog physical efficiency Rapid Flow mistake, the second vertical chord of contact 2 removes after part dust and droplet, by the first more intensive vertical chord of contact 1, the first vertical chord of contact 1 can be tackled a not part for easily collecting of dust-laden fog body, meanwhile, because most of dust, droplet are got rid of in dust-laden fog body, the first intensive vertical chord of contact 1 can not hinder gas flow mistake.
The projection of oblique chord of contact 5 on lower wheel disc 3 on the lower one end of flange connector 13 overlaps with lower flange connector 13 tie points with a 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 second adjacent vertical chord of contact 2; The projection of oblique chord of contact 5 on upper wheel disc 4 is crossing with two adjacent the first vertical chord of contacts 1; The projection in vertical direction of oblique chord of contact 5 forms " Z " font with the adjacent vertical chord of contact in upper and lower wheel disc.Oblique chord of contact 5 is interspersed and has increased footprint with vertical chord of contact, is conducive to strengthen the trapping to the droplet in gas and dust, has improved the collecting effect of dedusting day with fog part.
The diameter of the first vertical chord of contact 1, the second vertical chord of contact 2, oblique chord of contact 5 is 0.2～1mm, and chord of contact can be drawn and be formed by corrosion resistant metal bar, as nickel-cadmium, stainless steel, titanium alloy etc.Also can use the macromolecular material that corrosion-resistant tensile strength is high to be made, for example, 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.Described interception face oblique and vertical chord of contact composition can form 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 also can use not corrosion resistant metal material 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.The motor 7 that starts 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 powder in gas, can a sprayer unit be set at the upwind place of runner, make dust in gas become the moistening sedimentation that is easy to, interception through catch net 11 is removed a part of agglomerate body material, while flowing through lower wheel disc 3, dust-laden fog stream is cut by the atwirl second vertical chord of contact 2, there is very large relative velocity with droplet chord of contact 2 vertical with second in the dust in air-flow now, droplet or wet dust are because filtering, interception, collision effect is dammed on the second vertical chord of contact 2, descend the rotation of wheel disc 3 to drive flow rotation simultaneously, large drop in gas and bulk dust get rid of after cylinder inboard wall collides with it and rest on barrel under the effect of centrifugal force.
The second vertical chord of contact 2 of rotation 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 in the middle of flow through lower wheel disc 3 and upper wheel disc 4 time, 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, make droplet and wet dust collide with each other, condense separated subsequently.Upper wheel disc 4 is identical with the action principle that lower wheel disc 3 is removed dust and droplet.The dust of separating 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, utilize the chord of contact rotating to remove cloud and avoided the problem of raising the efficiency by the parallel stack of sandwich construction, adopt the mode at interval between string, solve the too large problem of existing machinery dedusting day with fog resistance, realized the object that improves capture rate, simplifies modular structure.
