Abstract
The invention relates to a novel bag-type dust collector for removing dust from industrial high-temperature flue gas and is characterized in that the novel bag-type dust collector comprises an air inlet dust hopper (1), air inlet channels (2), exhaust channels (3), a blowing gas bag (7), a bypass flue duct (9) and a bypass dust hopper (14), wherein weighted double-flap valves are installed in the air inlet dust hopper (1) and the bypass dust hopper (14); the air inlet channels (2) and the exhaust channels (3) are respectively disposed on two sides of the dust collector body; air inlet valves (4) are disposed inside the air inlet channels (2); exhaust valves (5) are installed inside the exhaust channels (3); bypass valves (10) are disposed inside a bypass flue duct (9); and the blowing gas bag (7) is a double-row two-valve gas bag and is positioned on the top of the dust collector. The system of the dust collector operates stably, has long service life, can be examined and repaired when the dust collector is working, and has a good dedusting effect as a whole. In addition, the flue dust discharge reaches the national standard.
Description
Technical field
The invention belongs to industrial high temperature flue gas ash removal field, particularly relate to a kind of novel sack cleaner that is used for the industrial high temperature flue gas ash removal.
Background technology
Steel industry is carried out (GB9078-1996) middle dust pelletizing system concentration of emission requirement of national standard " industrial furnace atmosphere pollutants emission standards " at present.The Shanghai regional standard had been accomplished revision in 2009, " Shanghai City steel and iron industry atmosphere pollutants emission standards " regulation: existing source is 60 mg/m
3, new source 30 mg/m
3
Along with the variation of the fast development of China's steel and iron industry and structural adjustment in recent years and production pattern, existing discharge standard is carried out strict control to the discharging of dust granules thing, and the equipment technology that adopts at present has been difficult to satisfy the environmental requirement of energy-saving and emission-reduction.
Chinese industrial particle dust discharge amount was 670.7 ten thousand tons in 2008, and steel industry accounts for 15% of national dust discharge amount.Mostly the sack cleaner of iron and steel metallurgical industry use at present is middle part flue ash bucket air inlet structure form; This version makes that smoke inlet speed is too high, the air-flow skewness, and cause dust granules secondary back-mixing in the ash bucket; Cause the filter bag dust load to increase the weight of; The deduster running resistance increases, and to all having a strong impact in sack cleaner service life and dust removing effects, does not meet the energy-saving and emission-reduction development policies.Require the new reorganization and expansion task of the soot emissions deduster that brings up to standard to the application of novel sack cleaner provide for a long time, reliable market.
Summary of the invention
The object of the invention is exactly the deficiency to above-mentioned prior art; Provide in a kind of solution prior art smoke inlet speed too high; The air-flow skewness; Cause the problem of dust granules reentrainment of dust in the ash bucket, and by-pass flue can make deduster under the situation of operation, the novel sack cleaner that is used for the industrial high temperature flue gas ash removal with precoating dirt is overhauled in the bag chamber.
The present invention adopts technical scheme following:
A kind of novel sack cleaner that is used for the industrial high temperature flue gas ash removal; It is characterized in that it comprise air inlet ash bucket, inlet channel, exhaust passage, air intake valve, drain tap, on take off cover plate, winding-up gas bag, row winding-up, by-pass flue, bypath valve and bypass ash bucket; The double-deck flap valve of weight is housed in said air inlet ash bucket and the bypass ash bucket, and said inlet channel and exhaust passage lay respectively at deduster body both sides, and said air intake valve is loaded in the inlet channel; Said drain tap is loaded in the exhaust passage; Said bypath valve is loaded in the by-pass flue, and said winding-up gas bag is bivalve pattern gas bag side by side, and is positioned at dust remover roof.
Said air inlet ash bucket, inlet channel, exhaust passage, air intake valve, drain tap, on to take off unit that cover plate, winding-up gas bag, row winding-up, by-pass flue, bypath valve and bypass ash bucket form single or at least two and be unified into deduster.
Beneficial effect of the present invention has:
The present invention is arranged in the side of deduster with the flue gas inlet channel, has avoided smoke inlet speed too high, the air-flow problem of uneven distribution; Simultaneously, use the double-deck flap valve of weight and side by side dual valve type gas bag structure make automatic ash-discharging more effective; Gas bag, pneumatic operated valve adopt gas circuit and air accumulator separately, and independent generation of each system influences each other, and system stable operation, increase service life; Increase by-pass flue, when the convenient bag chamber goes wrong, can under the deduster operation conditions, overhaul; When flue gas directly got into exhaust pass through by-pass flue, the dust of sedimentation can be laid down through the bypass ash bucket.Below all improved the whole dust removing effects of clarifying smoke system, made the soot emissions requirement that is up to state standards.
Description of drawings
Fig. 1 is a vertical view of the present invention.
Fig. 2 is a front view of the present invention.
Fig. 3 is a side view of the present invention.
Wherein: 1-air inlet ash bucket, 2-inlet channel, 3-exhaust passage, 4-air intake valve, 5-drain tap; The last cover plate of taking off of 6-, the 7-gas bag of jetting, the capable winding-up of 8-, 9-by-pass flue, 10-bypath valve; 11-bag-type dust district, 12-smoke inlet, 13-exhanst gas outlet, 14-bypass ash bucket.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further:
Shown in Fig. 1-3; The present invention includes air inlet ash bucket 1, inlet channel 2, exhaust passage 3, air intake valve 4, drain tap 5, on take off cover plate 6, winding-up gas bag 7, row winding-up 8, by-pass flue 9, bypath valve 10 and bypass ash bucket 14; The double-deck flap valve of weight is housed in air inlet ash bucket 1 and the bypass ash bucket 14, and inlet channel 2, exhaust passage 3, by-pass flue 9 all are positioned at deduster body both sides, and air intake valve 4 is loaded in the inlet channel 2; Drain tap 5 is loaded in the exhaust passage 3; Bypath valve 10 is loaded in the by-pass flue 9, and winding-up gas bag 7 is bivalve pattern gas bags side by side, is positioned at dust remover roof.Air inlet ash bucket 1, inlet channel 2, exhaust passage 3, air intake valve 4, drain tap 5, on take off unit that cover plate 6, winding-up gas bag 7, row winding-up 8, by-pass flue 9, bypath valve 10 and bypass ash bucket 14 form can be single or at least two and be unified into deduster.
Like Fig. 1, Fig. 2, Fig. 3; When the present invention works; Ash-laden gas gets into air inlet ash bucket 1 by smoke inlet 12; Big dust particle is because effects such as inertial collision, natural subsidence directly fall into air inlet ash bucket 1, and all the other dust are crossed inlet channel 2 entering bag-type dust districts 11 with air communication and filtered, and the clean gas after the filtration is 3 discharges from the exhaust passage.The dust that accumulates in the air inlet ash bucket 1 is realized automatic ash-discharging through the double-deck flap valve of weight; The dust that accumulates in bag-type dust district 11 is through winding-up gas bag 7 jet gas, forms air wave, comes off thereby make filter bag produce rapid expansion and impact shock.Overhaul or during precoating dirt, can keep deduster to continue operation when the bag chamber, open bypath valve 10; Close air intake valve 4; Ash-laden gas directly gets into by-pass flue 9 by inlet channel 2, gets into exhaust pass through bypath valve 10, and big dust particle is through effects such as inertial collision, natural subsidence; Fall into bypass ash bucket 14, the dust that accumulates in the air inlet ash bucket 14 is realized automatic ash-discharging through the double-deck flap valve of weight.
The undeclared part of other that the present invention relates to is identical with prior art.
