Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention such as involved each component
Shape, construction, the mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
As shown in figure 1, the invention provides a kind of New type wet coal mine dust remover, including shell 1, dust shield 2, and exhaust
Cover 3, and the dust shield 2 and hood 3 are separately mounted to the left and right ends of shell 1, so that deduster forms text on the whole
The working effect of venturi.
The right-hand member of dust shield 2 and shell 1 junction is provided with external jacket 4, and the inside of external jacket 4 and shell 1 connect
Synapsis is provided with orifice 5, and the external jacket 4 is connected with mixing valve 11, and the mixing valve 11 is connected with penstock 13 and wind-pressure tube
12, another valve port of the mixing valve 11 is connected with injection flow nozzle 18 by pipeline, is sprayed in the atomization gas-liquid of injection jet nozzle
Stream is acted on, and venturi " vacuum " region is formed in deduster inner chamber, due to the injection jet nozzle 18 of sucked type so that in jet flow
Larger " pull of vacuum " can be formed in effect, so as to effectively drive the rotation of air-flow.
The injection flow nozzle 18 is connected with fore-stock 7, and the injection flow nozzle 18 and the junction of fore-stock 7 are provided with grid
Net 17, the center of fore-stock 7 is provided with main shaft 10, and the main shaft 10 and is provided with Dust collecting net 9, and the Dust collecting net 9 passes through
Net housing 15 is fixed on main shaft 10, by the motor-driven rotation of main shaft 10, and dirt is caught by what drive cross alternative expression was installed
Net 9 can the sufficient contact with gas liquid mixture, the dust being atomized so as to effective seizure.
The other end of main shaft 10 is arranged on the center of after-poppet 6, and the right side of the after-poppet 6 is provided with steel mesh 8, convex globoidal it is close
Intensity is big, and the small steel mesh 8 in gap will form moisture film on surface, will be condensed and realize that final dusting is imitated when gas liquid mixture passes through
Really, the right side of steel mesh 8 is provided with drier 16, and drier 16 goes out steam, discharges clean air.
As shown in Fig. 2 the interior rotating side inside the injection jet nozzle that the deduster passes through sucker shape, atomized water is spraying injection
Rotation is produced during jet nozzle, cone inclined-plane will change the pressure state of atomized water, when going out flow type pump with injection water jet, form diffusion type spray
Mist, the degree of mixing of increase in the lumen, so that Dust collecting net preferably contacts gas-liquid mixture.
As shown in figure 3, the deduster is by setting half section Dust collecting net, set on dirt face two by two fixations catching
The parallel surface that axis is fixed, and angle is scheduled on into one with Dust collecting net, while driving Dust collecting net to rotate by driving shaft, due to
The presence of parallel surface will form certain interior rotational airflow so that in formation venturi " vacuum " of injection jet nozzle, produce one
Fixed feed effect certainly, improves the efficiency for catching dirt, by the gap between two parallel surfaces, and atomization gas-liquid mixture will pass through
When produce larger turbulence, while parallel surface will increase the adsorption area of overall Dust collecting net.
The drier 16 uses fluidized drier：The side that granular solids material is dried with fluidization technology
Method；In fluid bed, particle is dispersed in thermal current, is stirred up and down, is mutually mixed and is collided, again with big between air-flow and particle
Contact area, therefore fluidized drier have higher volumetric heat transfer coefficient.In fluidized drier, hot-air or flue gas
Through gas distribution grid enter fluidisation it is material bed in.Wet stock directly adds bed, is sufficiently mixed with the dry material in bed.Gas-solid
Two-phase carries out heat transfer and mass transfer in fluid bed, (heavy see centrifugation through cyclone separator through the gas of fluid bed
Drop) reclaim entrained with dust after leave away, dry products, from discharging opening overflow.
Venturi effect：Venturi effect, also referred to as venturi effect.This phenomenon is with its finder, Italian physicist
Venturi is named.The effect shows restricted flow in the flow section by diminution, and the phenomenon of flow velocity increase occurs in fluid,
Its flow velocity is inversely proportional with flow section.And the reduction of the adjoint Fluid pressure of the increase of flow velocity is known by Bernoulli's theorem, i.e., it is common
Venturi phenomenon.Generally, this effect refers to that low pressure can be produced near swiftly flowing fluid, makees so as to produce absorption
With.Venturi tube can be produced using this effect, the principle of Venturi effect is then when blowing air over obstacle, in obstacle
Lee face above near ports air pressure it is relatively low, so as to produce suction-operated and cause the flowing of air.The original of Venturi tube
Reason is in fact very simple, it be exactly air-flow from the coarse to fine, to accelerate gas flow rate, gas is formed in the rear side of venturi outlet
One " vacuum " area.Certain suction-operated can be produced to workpiece when this region of no pressure is close to workpiece.
The present invention realizes the seizure to pneumatic dust in deduster by using the air current flow pattern of venturi principle,
Dedusting operation is carried out, has been atomized the gas-liquid from wind-pressure tube and penstock by setting external jacket and orifice, outside deduster
Atomization wall is formed in shell, the liquid in gas and penstock in wind-pressure tube is mixed using mixing valve, external jacket is delivered to respectively
With injection jet nozzle, while injection jet nozzle sprays the atomization particle water air-flow along shell radial direction, at this moment near dust shield mouthful
Certain negative pressure will be formed, will be sucked positioned at the dust of dust shield mouthful in deduster, while dust can be by being atomized wall and water
Vapour contacts to form certain free gas liquid mixture, is driven by the air-flow of injection jet nozzle, to internal diameter of outer cover to movement, this
When main shaft rotated by motor, drive Dust collecting net rotate, move in the gas flow by gas-liquid mixed dust capture in Dust collecting net
On, due to the design of right-angled intersection formula so that Dust collecting net can sufficient contact ionization gas liquid mixture.
While dust is adhered to, due to the rotation of main shaft, dust is when being accumulate to certain amount of seizure, due to gravity
It will be peeled off with the double action of centrifugal force from Dust collecting net, into collecting chamber, the gas after processing is big by closeness, and gap is small
Steel mesh condensation and absorption, form partial desiccation gas, then by the appropriate drying of drier, will discharge in hood totally
Air, and dust is in collecting chamber, can also very easily handle, and has at the same time also beautified the building ring of workman significantly
Border, this will also greatly improve operating efficiency.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that method of the present invention design and technical scheme are carried out is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.This hair
Bright protection domain should be determined by the scope of protection defined in the claims.
