Adopt aiutage dust arrester installation of the present invention, the dedusting tube is positioned at a side of aiutage, be provided with first valve between the air inlet of aiutage and the exhaust outlet, when the aiutage dust arrester normally uses, first valve closing, the gas that carries dust flows through from the dedusting tube, and dust is removed under the effect of liquid-jet device.Aiutage dust arrester installation of the present invention has thoroughly solved the dust blockage problem of aiutage, has improved production efficiency.In addition,, therefore in the environment that has poison gas to produce, also avoided directly taking apart aiutage and come it is cleared up, thereby avoided poison gas to leak, improved the security performance of system's operation because aiutage can not stop up.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the system architecture schematic diagram according to aiutage dust arrester installation of the present invention.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Aiutage dust arrester installation as shown in Figure 1 comprises: aiutage 10, have air inlet and exhaust outlet, and be provided with first valve 11 between air inlet and the exhaust outlet; Dedusting tube 20 is positioned at a side of aiutage 10, and its inlet is connected with the air inlet of aiutage 10, and its outlet is connected with the exhaust outlet of aiutage 10; Liquid-jet device 30 is arranged at the inside of dedusting tube 20, and sprays dedusting liquid downwards.
When the aiutage dust arrester normally used, first valve 11 was closed.As the arrow of the dotted line among Fig. 1 direction pointed, the gas that carries dust flows into the inlet of dedusting tube 20 from the air inlet of aiutage 10, gas is through after the dedusting tube 20, dust is removed under the effect of liquid-jet device 20, gas after the dedusting flows out from the outlet of dedusting tube 20, and discharges from the exhaust outlet of aiutage 10.
According to one embodiment of present invention, the aiutage dust arrester is used for add-on systems such as zinc powder, oxide powder and zinc, calcining.In these systems, the as easy as rolling off a log generation airborne dust of powder, special dust very easily enters aiutage under the condition of negative pressure of aiutage exhausting, causes aiutage to stop up, and makes troubles to production, and the cleaning aiutage needs to stop.This aiutage dust arrester installation has thoroughly solved the dust blockage problem of aiutage, has improved production efficiency.In addition, if cause the obstruction of dust such as zinc powder in the aiutage that poison gas production is arranged, bring greatly difficulty can for the cleaning aiutage, the cleaning personnel need be equipped with the positive-pressure type respirator just can finish cleaning work.After the aiutage dust arrester installation was set, aiutage can not stop up, and had therefore avoided directly taking apart aiutage in the environment that has poison gas to produce yet and had come it is cleared up, thereby avoided poison gas to leak, and had improved the security performance of system's operation.
Be provided with second valve 12 between the air inlet of the inlet of dedusting tube 20 and aiutage 10, be provided with the 3rd valve 13 between the exhaust outlet of the outlet of dedusting tube 20 and aiutage 10.
When need maintain or keep in repair dedusting tube 20, dedusting tube 20 and aiutage 10 need be separated.When dedusting tube 20 is maintained or keeps in repair, second valve 12 that is provided with between the air inlet of the inlet of dedusting tube 20 and aiutage 10 and the 3rd valve 13 that is provided with between the exhaust outlet of the outlet of dedusting tube 20 and aiutage 10 are closed, and first valve 11 that is provided with between the air inlet of aiutage 10 and the exhaust outlet is opened, and gas is directly discharged from aiutage 10.When routine was used 20 dedustings of dedusting tube, second valve 12 and the 3rd valve 13 all were in opening, make dusty gas can flow into dedusting tube 20, and flow out from dedusting tube 20 after dedusting.
Be provided with filler in the dedusting tube 20.Preferably, filler is a silk floss.Perhaps, filler is a silica gel.
Be provided with filler in the dedusting tube 20, dusty gas flows through from filler, and filler is a relatively more loose material such as silk floss or silica gel, and dusty gas fully contacts and is removed with the dedusting liquid of liquid-jet device ejection in loose filler.
As shown in Figure 1, liquid-jet device 30 is arranged at the top of filler.
Liquid-jet device 30 is arranged at the top of filler, and sprays dedusting liquid downwards.The direction of motion of dedusting liquid is opposite with the direction of motion of dusty gas, thereby makes the two have adequate time to contact, and has optimized the effect of dedusting.Dedusting liquid is various acid solutions, alkali lye or neutral solution, selects the classification of dedusting liquid according to the classification of the dust that will remove, selects easily to make the liquid of dust dissolving in principle, if fail to make the liquid of dust dissolving, should consider to have the liquid of effective flushing action.
The aiutage dust arrester installation also comprises dedusting liquid circulating slot 50, and an end of dedusting liquid circulating slot 50 is connected with the lower end of dedusting tube 20, and its other end connects an end of circulating pump 40.Preferably, the other end of circulating pump 40 is connected with liquid-jet device 30.
Dedusting liquid circulating slot 50 has been realized recycling to dedusting liquid, dedusting liquid flows into dedusting liquid circulating slot 50 from the fluid collection portion of the lower end of dedusting tube 20, after handling in dedusting liquid circulating slot 50, the dedusting liquid after the processing enters new circulation by circulating pump 40.In one embodiment of the invention, circulating pump 40 directly is connected with liquid-jet device 30, dedusting liquid flows directly into liquid-jet device 30 through the effect of circulating pump 40, and spray downwards the dedusting that contacts with dusty gas, the final fluid collection portion that flows into the lower end of dedusting tube 20 downwards, and flow into dedusting liquid circulating slot 50 again, finish a circulation.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
Aiutage dust arrester installation of the present invention has thoroughly solved the dust blockage problem of aiutage, has improved production efficiency.In addition,, therefore in the environment that has poison gas to produce, also avoided directly taking apart aiutage and come it is cleared up, thereby avoided poison gas to leak, improved the security performance of system's operation because aiutage can not stop up.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
