Abstract
The invention provides a dust removal device for a stirrer. The dust removal device effectively prevents fly ash from flying in a stirring process, avoids environmental pollution and effectively guarantees operation of previous level of equipment and human body health simultaneously. The dust removal device comprises the stirrer and is characterized in that a cylinder is arranged on the stirrer and communicated with the stirrer, atomizing nozzles are arranged in the cylinder, and filter screens are arranged above the atomizing nozzles in the cylinder.
Description
Technical field
The present invention relates to the technical field of incineration of refuse flyash solidification and stabilization treating apparatus, relate to a kind of dust arrester of agitator particularly.
Background technology
Because country's recent years just requires that flying dust wants landfill after solidification and stabilization, also there is no producer at present for the special treatment facility of the material manufacture of this characteristic of flying dust.That run at present and be adopt concrete mixer substantially at the flyash curing stabilisation mixing plant of founding a capital.The characteristic of concrete, cement mortar is normal temperature, have no irritating odor, with not heat release during water mix and blend, also would not produce a large amount of dust-laden steam.And flyash ingredient is complicated, temperature is higher, and wherein containing calcium hydroxide, and common concrete mixer there is no special dust removal installation, flying dust can be produced fly upward in whipping process, cause the pollution of environment, can produce a large amount of pungent dust-laden steam when flying dust and water mix and blend, the operation not only affecting upper level equipment also has very large harm to health.
Summary of the invention
For the problems referred to above, the invention provides a kind of dust arrester of agitator, the flying dust that effectively prevent in whipping process flies upward, and avoids the pollution of environment, effectively ensure that health simultaneously.
Technical scheme of the present invention is such, a kind of dust arrester of agitator, comprise agitator, it is characterized in that: described agitator is provided with cylindrical shell, described cylindrical shell is communicated with described agitator, be provided with atomizer in described cylindrical shell, the inherent described atomizer upper end of described cylindrical shell is provided with filter screen.
It is further characterized in that: described cylindrical shell is provided with and takes out dirt blower fan; In described cylindrical shell, corresponding described filter screen upper end is provided with back flushing nozzle; The inherent described atomizer upper end of described cylindrical shell is provided with multiple filtration screen cloth, and described filter screen is in tilted layout; Described cylindrical shell comprises upper shell and lower shell, and described atomizer is arranged in described lower shell, and described filter screen and described back flushing nozzle are arranged in described upper shell.
In said structure of the present invention, agitator is provided with cylindrical shell, cylindrical shell is communicated with agitator, atomizer is provided with in cylindrical shell, the inherent atomizer upper end of cylindrical shell is provided with filter screen, when the material such as flying dust, water enters mixer simultaneously, atomizer action, the dust that atomized water adverse current catches in gas forms water droplet, then water droplet is down in mixer due to initial velocity inertia and deadweight, and the material that part is flown upward is filtered by filter screen, and the flying dust that effectively prevent in whipping process flies upward, avoid the pollution of environment, effectively ensure that health simultaneously.
Accompanying drawing explanation
Fig. 1 is the dust arrester front view of agitator of the present invention.
Detailed description of the invention
See Fig. 1, a kind of dust arrester of agitator, comprise agitator 1, agitator 1 is provided with cylindrical shell 2, cylindrical shell 2 is communicated with agitator 1, atomizer 3 is provided with in cylindrical shell 2, cylindrical shell 2 inherent atomizer 3 upper end is provided with filter screen 4, flying dust, when the materials such as water enter mixer simultaneously, atomizer action, the dust that atomized water adverse current catches in gas forms water droplet, then water droplet is down in mixer due to initial velocity inertia and deadweight, the material that part is flown upward is filtered by filter screen, the flying dust that effectively prevent in whipping process flies upward, avoid the pollution of environment, effectively ensure that health simultaneously.
Cylindrical shell 2 is provided with and takes out dirt blower fan 5, make in agitator, to produce certain negative pressure by taking out dirt blower fan, dust-containing water steam in agitator is discharged after being towed to the concentration filter dedusting of dust arrester place, both prevented dust-laden steam from entering higher level equipment, ensure that the normal operation of upper level equipment, when agitator Dump gate can also be avoided to open, in agitator, dust-laden steam sprays along discharge port.
In cylindrical shell 2, corresponding filter screen 4 upper end is provided with back flushing nozzle 6, back flush is carried out to the mixture of the dust be adsorbed on screen cloth and water, back flushing nozzle adopts pulse control instrument to control to carry out backwash to the reverse side of screen pack, the sewage backflow produced, in mixer, effectively prevent the blocking of screen cloth.
Cylindrical shell 2 inherent atomizer 3 upper end is provided with multiple filtration screen cloth 4, filter screen 4 is in tilted layout, the sewage produced is back in mixer along cylinder inboard wall, be in tilted layout and prevent sewage, sludge retention on screen cloth and sewage, sludge reflux clash into material in mixer, multilayer screen cloth flexible arrangement plays multi-filtering, improves the filter effect of dust.
Mechanism structure simply, not takes up space, and can be directly installed on concrete mixer, and active balance mixer inner and outer air pressure is poor, avoids the steam in equipment to enter higher level equipment, the normal operation of interference upper level equipment.The airborne dust of adsorption filtration simultaneously, avoids dust pollution environment.
In the present embodiment, cylindrical shell comprises upper shell 2-1 and lower shell 2-2, atomizer is arranged on lower shell 2-2, filter screen 4 and back flushing nozzle 6 are arranged on upper shell 2-1, be separated with the dismounting of lower shell by upper shell, facilitate the installation of the atomization nozzle of cylindrical shell, filter screen and back flushing nozzle.
