Description
Technical field
The utility model relates to dust collecting in a kind of waste gas, relates in particular to a kind of carbon black wet granulation waste gas carbon powder dust gathering-device.
Background technology
Present domestic wet method carbon black process; wet granulator; the wet granulation carbon black that forms; pass through drying machine; with enter dry fire-box from the about 1100 ℃ hot flue gas of tail-gas combustion stove; after hot flue gas heats the wet method carbon black indirectly with the drying machine cylindrical shell earlier; enter dryer inner again and wet carbon black carries out Direct Contact Heating, slough the moisture content in the carbon black, the mist of granulation water generates steam in hot flue gas and the wet carbon black; usually be referred to as waste gas; contain carbon powder dust in the waste gas, through exhaust piping, by exhaust gas fan; deliver to four waste gas (anti-bleed type) bag hose respectively; carbon powder dust in the waste gas is trapped in filter bag inside, and the carbon black smoke with main bag pressurizes through the waste gas back blowing machine then, by a cover blowback program; periodically purge successively; carbon black falls into the awl bucket and enters air delivery pipe, again through the micron pulverizer, through the wind pressure fan; deliver to separator, enter wet granulator again.Former gas sampling exists filter efficiency low, and filtration resistance is big, often makes dry fire-box malleation occur, the situation that flue gas and carbon powder dust leak, because the waste gas maldistribution, and make indivedual spin manifold temperatures on the low side, the awl bucket easily forms carbon black mud and stops up, and causes indivedual bag hoses to lose filtering function.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon black wet granulation waste gas carbon black gathering-device, this device purges the big characteristics of carbon black ability with the pulse packet filter, carbon black purges effective, the air permeability and good that has kept filter bag, change the bag hose structure simultaneously and change a casing into by four casings that are separated from each other, solve the phenomenon of waste gas distribution and spin manifold temperature inequality, realize the operate as normal of wet granulation waste gas carbon black gathering system.
The utility model is achieved like this; it comprises the pulsed bag hose; air delivery pipe; the micron pulverizer; blower fan; separator; wet granulator; drying machine; dry fire-box; tail-gas combustion stove; exhaust piping; the waste gas air exhauster; it is characterized in that connecting the pulsed bag hose successively by air delivery pipe; the micron pulverizer; blower fan; separator and wet granulator; wet granulator connects drying machine; drying machine is installed in the dry fire-box; dry fire-box connects tail-gas combustion stove; drying machine connects the waste gas air exhauster successively by exhaust piping, and the waste gas air exhauster connects the pulsed bag hose.
Technique effect of the present utility model is: 1, save equipment investment and maintenance operating cost, energy-conservation joint Zhi Xiaoguo is obvious; 2, improved being attached to the purging ability of filter bag surface carbon black, make filter bag keep air permeability and good, improved the filter efficiency of filter bag greatly, make the ability of regulation and control of the little negative pressure of dry fire-box strengthen greatly, substantially stop leaking of dry fire-box dry flue gas and carbon powder dust, improved work situation greatly; 3, improve the filter efficiency of bag hose, made drying machine and dry fire-box dry flue gas flow velocity improve, strengthened the efficient of hot flue gas and wet carbon black heat exchange, thereby saved the fuel (carbon black tail gas) of tail-gas combustion stove, saved the energy; 4, overcome the phenomenon of distribution and temperature inequality, bag hose spin manifold temperature control ability is strengthened greatly, solved the easily stifled phenomenon of waste gas bag hose cone carbon black fully, make this system works more stable, reduced the bag hose fault, improve the waste gas life of bag filter, thereby alleviated working strength of workers greatly.

Pulsed bag hose 2, air delivery pipe 3, micron pulverizer 4, blower fan 5, separator 6, wet granulator 7, drying machine 8, dry fire-box 9, tail-gas combustion stove 10, exhaust piping 11, waste gas air exhauster in the drawings, 1,
The specific embodiment
As shown in Figure 1; the utility model is achieved like this; connect pulsed bag hose 1, micron pulverizer 3, blower fan 4, separator 5 and wet granulator 6 successively by air delivery pipe 2; wet granulator 6 connects drying machine 7; drying machine 7 is installed in the dry fire-box 8; dry fire-box 8 connects tail-gas combustion stove 9, and drying machine 7 connects waste gas air exhauster 11 successively by exhaust piping 10, and waste gas air exhauster 11 connects pulsed bag hose 1.The waste gas that drying machine 7 produces by exhaust piping 10, is sent waste gas into pulse packet filter 1 by waste gas air exhauster 11, enters from bag hose bottom awl bucket, and the carbon powder dust in the waste gas is delayed at the outside of filter bag, by a cover purging system, uses 4-5kg/cm
2Compressed air, periodically outwards purge by pulse valve investing filter bag surface carbon black from filter bag inside, the carbon black that invests the filter bag surface is under the effect of high voltage pulse air-flow; come off from the filter bag surface; through natural subsidence, fall into awl bucket after, enter blast system; deliver to the comminutor granulation; filter bag recovers original gas permeability after purging, and enters next round and filters, again purge; so again and again the carbon black in the waste gas is filtered and collect the direct emptying of waste gas behind the filtration carbon powder dust.
