The large-scale furnace flue gas sack cleaner generally using in engineering is the double structure that is arranged in juxtaposition more, flue gas inlet box and go out the centre that gas tank is all located at two row's dedusters, and all pre-charge device is not set, not high to minuteness particle arresting efficiencies such as PM2.5.
Summary of the invention
The purpose of this utility model is to be the double structure that is arranged in juxtaposition for large-scale furnace flue gas sack cleaner more, to not high problems of minuteness particle arresting efficiency such as PM2.5, a kind of pre-charged sack cleaner is provided, traditional pocket type cleaner reform is become can strengthen to the pre-charged sack cleaner of flue dust minuteness particle trapping, improve the arresting efficiency of sack cleaner to minuteness particle.
Technical solution of the present utility model is: a kind of pre-charged sack cleaner, comprise pre-charge device and sack cleaner, sack cleaner is double to be arranged in juxtaposition, pre-charge device is arranged between two row sack cleaners, pre-charge device can make dust charged, is also the air intake passage of sack cleaner.
Pre-charge device described in the utility model, comprises top board, inclined bottom plate, discharge electrode, earthing pole; Earthing pole is arranged on both sides and the central authorities of top board, inclined bottom plate, the space that top board, inclined bottom plate, earthing pole form forms inlet channel, inlet channel is arranged between two row sack cleaners, and inlet channel is deduster air intake passage, is again pre-charged dust space.Discharge electrode is set in inlet channel, and discharge electrode adopts the form of sub-assembly to hang by insulating suspension porcelain vase, and deashing device, high voltage source are installed on top board; Deashing device is arranged on discharge electrode top, and high voltage source is connected with insulating suspension porcelain vase by wire, and earthing pole connects with the earth by welding.
Discharge electrode described in the utility model can be the different discharge electrode forms such as prickle wire, astroid, circle line, and discharge electrode quantity is adjustable.
Earthing pole described in the utility model can be the pole plate of porous plate, flase floor, meshed polar plate or other form, and earthing pole quantity is adjustable.
Deashing device described in the utility model can be top rapping device, sound wave ash cleaner, pulse jetting deashing device etc.
Sack cleaner described in the utility model, it comprises middle casing, upper box, ash bucket, filter bag, pulse spraying equipment, air outlet etc.Casing is installed on middle casing top, and filter bag is suspended on the card of upper box, and pulse jetting deashing device is set in upper box, and ash bucket is installed in the below of middle casing, and air outlet is arranged on the tail side of upper box.
Sack cleaner upper box described in the utility model, its inside is UNICOM, can be used as exhaust passage, its afterbody side sets out air port.
The operation principle of pre-charged sack cleaner described in the utility model is: high voltage source applies high pressure to discharge electrode, between discharge electrode and earthing pole, sets up electric field, and discharges electric charge.When flue gas enters after inlet channel, flow from front to back, in flow of flue gas process, dust is charged, and the dust after charged enters sack cleaner with flue gas and filters, and the flue gas after purification is discharged from upper box afterbody air outlet.When discharge electrode adheres to after a certain amount of dust, deashing device is to discharge electrode deashing; After a certain amount of dust of filter bag of dust collector surface attachment, pulse jetting deashing device work, to filter bag ash removal, the dust coming off falls into ash bucket.
