Abstract
The utility model discloses a dry-type reaction and sack dusk-removing integrated device with outer circulation. The dry-type reaction and sack dusk-removing integrated device with the outer circulation comprises a sack dust removing device, a dry-type reaction device and an outer circulation pipeline. The dry-type reaction device and the sack dust removing device are designed together, a feed bin of the dry-type reaction device is fixed on the outer wall of the sack dust removing device, and a gradual enlargement section of the dry-type reaction device is taken as an entrance of the sack dust removing device. The outer circulation pipeline is arranged on the sack dust removing device, and a high-pressure fan is used for sending back part of dust exhausted from the sack dust removing device to the dry-type reaction device for recycling. The dry-type reaction and sack dusk-removing integrated device with the outer circulation has the advantages of being capable of reducing occupied area, improving dry-type reaction efficiency, reducing drug usage amount, and ensuring that smoke reaches a standard.
Description
Technical field
The utility model relates to a kind of dry type reaction and bag-type dust integrated device with the dust outer circulation.This device is mainly used in the incinerator field.
Background technology
At present, in the incinerator system, all be to adopt the dry type reaction unit of venturi form independently and sack cleaner independently, in use pulverized limestone and activated carbon powder are behind the dry type reaction unit, enter sack cleaner through a segment pipe, after the dust of sack cleaner is blown off, discharge through ash bucket, owing in the danger waste burning process, enter content the unknown of acid gas in flue gas and the bioxin of dry type reaction unit, generally all be the excessive with medicament that makes therefore, cause the medicament waste, because the dry type reactor outlet has a segment pipe, so that the pulverized limestone of larger particles and activated carbon powder stockpile, affect result of use in pipeline simultaneously.
In order to overcome existing issue, the utility model provides a kind of dry type reaction and bag-type dust integrated device with the dust outer circulation, the double sack cleaner inlet ductwork of doing of dry type reaction unit throat outlet divergent segment, in pipeline, be provided with airflow-distribution board, at sack cleaner ash hole place, utilize high-pressure blast that the part dust is blown back dry type reactor throat, increase the medicament service efficiency.
Summary of the invention
In order to overcome existing dry type reaction unit and sack cleaner existing problems, the utility model provides a kind of dry type reaction and bag-type dust integrated device with the dust outer circulation.
The technical scheme that its technical problem that solves the utility model adopts is: the flue gas that quench tower comes enters venturi dry type reaction unit, pulverized limestone and activated carbon powder feed bin directly are fixed on the sack cleaner outer wall, feed bin is arranged with charging gear, activated carbon powder and pulverized limestone add through the throat of dispenser from venturi dry type reaction unit, venturi dry type reactor divergent segment is arranged to square horn structure, the double sack cleaner inducer of doing of divergent segment, flue gas is with after active carbon and pulverized limestone fully mix, through being arranged on the airflow-distribution board in the dry type reactor divergent segment square structure, enter sack cleaner, pulverized limestone and activated carbon powder are attracted to the cloth bag surface, when flue gas passes cloth bag through these medicaments, the residue sour gas fully contacts with pulverized limestone and reacts in the flue gas, and the De bioxin also is attached to the active carbon dust absorption on cloth bag surface in the flue gas, sack cleaner ash bucket bottom arranges star-like ash hoist, the ash hoist outlet links to each other with a four-way, after the deashing time arrives, dust is shaken off to ash bucket, when discharging through ash hoist, the part dust is blown into dry type reactor throat by pressure-air, recycles.
