Description
Technical field
The present invention relates to a kind of deduster, especially a kind of sack cleaner applied to SCR method denitrating systems.
Background technology
Currently, before denitration reaction is carried out using SCR methods denitrating system, it is one of important procedure therein that flue gas when reacting denitration catalyst, which carries out dust removal process,.In general, general sack cleaner carries out flue gas ash removal.
The structure of existing sack cleaner is as follows：Including upper box, middle case and ash bucket, wherein the side wall of ash bucket is provided with air inlet, and valving is provided with the ash hole of ash bucket, and filter bay assembly is lifted with middle case, soot blower system is provided with upper box, and air outlet is provided with one of side wall of upper box.Problems be present in this sack cleaner：(1) when actually carrying out dedusting operation, because the blast of flue gas stream is larger, the flue gas stream skewness to middle case is passed through from air inlet, most of flue gas stream concentrates on the side of the middle case corresponding with air inlet, so as to have a strong impact on dust removing effects；(2) because the dust-laden particulate matter in flue gas is more, and the blast of flue gas stream is larger, and when flue gas stream is directly passed through into ash bucket from air inlet, strong impact is caused to the madial wall of ash bucket, has a strong impact on the service life of ash bucket；(3) soot blower system design is unreasonable, causes compressed air can not clean out the dust adsorbed on dedusting filtering bag, ash-removal effect is bad.
The content of the invention
Present invention aim to solve the problem above present in current sack cleaner, the sack cleaner for SCR method denitrating systems that a kind of ash-removal effect is good, efficiency of dust collection is high, service life is grown is provided for this.
The present invention concrete scheme be：A kind of sack cleaner, including upper box, middle case and ash bucket, wherein the side wall of ash bucket is provided with air inlet, and valving is provided with the ash hole of ash bucket, filter bay assembly is lifted with middle case, soot blower system is provided with upper box, and air outlet is provided with one of side wall of upper box, it is characterized in that：Several deep beads are provided with ash bucket, each deep bead is corresponding with air inlet respectively, and along a lateral offside of air inlet, arrangement from top to bottom is in stepped structure, is formed between adjacent two pieces of deep beads and divides wind air channel.
The inclined arrangement in side of heretofore described deep bead towards air inlet, the scope of inclined angle alpha is 0-10 degree.
Heretofore described valving is combined by push-pull valve and star-shaped dust-discharging valve.
Heretofore described filter bay assembly includes the card for being arranged on upper box bottom, and some card holes are offered on card, and a dedusting filtering bag is docked in each card hole, and dedusting filtering bag is opening up to be arranged and be lifted in middle case；The soot blower system includes compressed air bag and several injection tubes, and compressed air bag connects each injection tube, several nozzles is provided with each injection tube, each nozzle is corresponding with the opening of each dedusting filtering bag respectively.
The present invention is simple in construction, ingenious in design, ash-removal effect is good, and by arranging deep bead in ash bucket, the ash-laden gas of high pressure is prevented to the direct impact of ash bucket, extend the service life of ash bucket, realize simultaneously and the flue gas being passed through in middle case is carried out uniformly dividing wind to handle so that effective dedusting area increase in middle case, so as to improve efficiency of dust collection.

Embodiment
Referring to Fig. 1, Fig. 2, the present invention includes top box 1, middle case 2 and ash bucket 3, wherein the side wall of ash bucket 3 is provided with air inlet 4, and valving is provided with the ash hole of ash bucket 3, filter bay assembly is lifted with middle case 2, soot blower system is provided with upper box 1, and air outlet 5 is provided with one of side wall of upper box 1, particularly：Several deep beads 6 are provided with ash bucket 3, each deep bead is corresponding with air inlet 4 respectively, and along a lateral offside of air inlet 4, arrangement from top to bottom is in stepped structure, is formed between adjacent two pieces of deep beads and divides wind air channel 7.
Referring to Fig. 2, the inclined arrangement in side of deep bead 6 described in the present embodiment towards air inlet 4, the scope of inclined angle alpha is 0-10 degree.
Valving described in the present embodiment is combined by push-pull valve 8 and star-shaped dust-discharging valve 9.
Referring to Fig. 3, Fig. 4, filter bay assembly described in the present embodiment includes the card 10 for being arranged on the bottom of upper box 1, some card holes 11 are offered on card 10, a dedusting filtering bag 12 is docked in each card hole 11, and dedusting filtering bag 12 is opening up to be arranged and be lifted in middle case 2；The soot blower system includes compressed air bag 13 and several injection tubes 14, and the bag of compressed air 13 connects each injection tube 14, several nozzles 15 is provided with each injection tube, each nozzle is corresponding with the opening of each dedusting filtering bag respectively.
The present invention is when carrying out dedusting work, push-pull valve 8 is closed, ash-laden gas is passed through in ash bucket 3 from air inlet 4, in the presence of deep bead 6, it is therefore prevented that direct impact of the ash-laden gas to ash bucket, at the same time, wind air channel 7 is divided to carry out uniformly dividing wind to handle to the ash-laden gas being passed through between adjacent deep bead, ensure that ash-laden gas is equably passed through into middle case 2, and fully contacted with each dedusting filtering bag 12, substantially increase efficiency of dust collection.During dedusting, ash-laden gas is filtered through each dedusting filtering bag 12, and big particulate matter is fallen under gravity into ash bucket 3, and small particulate matter or aqueous vapor choked flow are in the outer surface of dedusting filtering bag 12, and the flue gas after filtration treatment is passed through into top box 1, and discharged from air outlet 5.
As deduster carries out dedusting operation for a long time, the particulate matter or aqueous vapor that are attached to the outer surface of dedusting filtering bag 12 can be continuously increased, and can so cause the resistance of deduster to rise, and have a strong impact on normal dedusting operation.At this time, it may be necessary to carry out deashing work to deduster, specific practice is：Open push-pull valve 8, and start star-shaped dust-discharging valve 9 and compressed air bag 13, compressed air is passed through into each injection tube 14, and blast cleaning is carried out to corresponding each dedusting filtering bag 12 by each nozzle 15 respectively, so that dedusting filtering bag 12 expands suddenly, the particulate matter or aqueous vapor for investing the surface of dedusting filtering bag 12 are dropped to rapidly in ash bucket 3, and after whole jetting deashings of dedusting filtering bag 12 terminate, deduster recovers normal work.
