Abstract
The utility model discloses a bag-type dust remover for a sintering machine head. The bag-type dust remover comprises a bag chamber and a dust hopper arranged at the lower end of the bag chamber, wherein the air inlet of the bag chamber is connected with an air intake flue; a plurality of filtering cloth bags are fixed in the bag chamber; and a centralized gas purifying chamber is arranged at the upper end of the bag chamber and is connected with a draft flue. In full consideration of the characteristics of dusty gas in the sintering machine head such as large negative pressure, large humidity, large temperature variation and the like, the bag-type dust remover adopting the centralized gas purifying chamber can not only bear high negative pressure, but also reduce air leakage to avoid dewing and burning bags, and has the advantages that the dust removing efficiency is insusceptible to change of working conditions during sintering production, and the outlet emission concentration can stably reach the new environment-friendly emission standard (smaller than 50 mg/Nm3).
Description
Technical field
The utility model belongs to the sack cleaner technical field, is specifically related to a kind of sintering machine head end sack cleaner.
Background technology
Characteristics such as the flue gas that the sintering machine of steel mill head is discharged has that negative pressure is big, high humidity, temperature fluctuation are big.And existing sintering machine head end smoke eliminator all is to adopt electric cleaner (mechanism is that static captures), and there is following defective in this device: efficiency of dust collection is subjected to the influence of extremely unsettled SINTERING PRODUCTION operating mode and fluctuation occurs; The outlet concentration of emission of deduster is difficult to stable to reach new environmental emission standard (less than 50mg/Nm
3); The discharging that exceeds standard had not only aggravated environmental pollution but also had influenced the physical and mental health of enterprise staff; The floor space and the construction investment of this device are huge.And existing sack cleaner exists dewfall to stick with paste the hidden danger of bag because can not adapt to the flue gas condition of high negative pressure and high humility, thereby fails to be used for the clarifying smoke of sintering machine head end.
The utility model content
The technical problems to be solved in the utility model is: the shortcoming that exists at prior art is with not enough, and a kind of sintering machine head end sack cleaner that can steady operation under the big operating mode of high negative pressure, high humility, temperature fluctuation is provided.
At above-mentioned technical problem, the utility model proposes following technical scheme: comprise the bag chamber that has air inlet and exhaust pass, and be arranged on bag ash bucket of lower end, chamber, air inlet is connected with the air inlet flue, at indoor several filtration cloth bags that is fixed with of bag, the upper end of bag chamber is provided with concentrated air-purifying chamber, concentrates air-purifying chamber to link to each other with exhaust uptake by exhaust pass.
The indoor air inlet that is positioned at of described bag of the present utility model is outside equipped with air flow regulator, offers the different hole of area on the described air flow regulator employing plate face and makes flue gas enter the cloth bag district in proportion; Indoor card and the locating rack of being provided with of bag, the upper end of filtering cloth bag is fixed on the card, and the lower end is fixed on the locating rack by the bolt pair; The pipeline of exhaust pass is provided with outlet valve; Be connected by by-pass flue between air inlet flue and the exhaust uptake, and in this by-pass flue, be provided with by-passing valve; By-pass flue passes from ash bucket; Ash bucket and by-passing valve link to each other with hot-air system by pipeline.
Beneficial effect of the present invention is embodied in: characteristics such as taken into full account that sintering machine head end ash-laden gas negative pressure is big, high humidity, temperature fluctuation are big, adopt and concentrate air-purifying chamber, can bear high negative pressure, can reduce again and leak out and then avoid dewfall and stick with paste bag, efficiency of dust collection is not subjected to the influence of SINTERING PRODUCTION fluctuation of operating conditions, and what the outlet concentration of emission can be stable reaches new environmental emission standard (less than 50mg/Nm
3).
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to Fig. 1, the ash bucket 14 that the utility model comprises bag chamber 4 and is arranged on 4 lower ends, bag chamber, the air inlet 2 of bag chamber 4 links to each other with air inlet flue 1, in air inlet 2, be provided with air flow regulator 3 in bag chamber 4 antepositions, offering the different hole of area on the described air flow regulator 3 employing plate faces makes flue gas enter the cloth bag district in proportion, be fixed with several in the bag chamber 4 and filter cloth bag 5, bag is provided with card 6 and locating rack 7 in the chamber 4, the upper end of filtering cloth bag 5 is fixed on the card 6, the lower end is fixed on the locating rack 7 by the bolt pair, the upper end of bag chamber 4 is provided with concentrates air-purifying chamber 8, concentrate air-purifying chamber 8 to link to each other with exhaust uptake 11 by the exhaust pass 9 on the bag chamber 4, the pipeline of exhaust pass 9 is provided with outlet valve 10, be provided with by-pass flue 12 between air inlet flue 1 and the exhaust uptake 11, by-pass flue 12 passes from ash bucket 14, is provided with by-passing valve 13 in the by-pass flue 12, and the closed chamber of ash bucket 4 and by-passing valve 13 links to each other with hot-air system 15 by pipeline.
The course of work of the present utility model is as follows: from the ash-laden gas of air inlet flue 1 air inlet 2 of flowing through earlier, because the effect of air flow regulator 3, make ash-laden gas ratio on request enter the cloth bag district that some filtration cloth bags 5 are housed from front portion, bottom and the rear portion of bag chamber 4 respectively, when ash-laden gas passes cloth bag from the outside of filtering cloth bag 5, because the filtration of cloth bag realizes dedusting.Be fixed on the locating rack 7 by the bolt pair owing to filter the lower end of cloth bag 5, make filtration installation site, cloth bag 5 bottom accurate, and then guarantee reliable dedusting.Flue gas after being purified is concentrated air-purifying chamber 8 through suitable for reading the entering of filtering cloth bag 5, and the exhaust pass 9 of flowing through then enters exhaust uptake 11.During the work of this device, outlet valve 10 is in opening, and by-passing valve 13 is in closed condition.When the temperature not normal (too high or too low) of ash-laden gas or the medial and lateral pressure reduction that filters cloth bag 5 transfinited, by-passing valve 13 was opened, and outlet valve 10 cuts out, and the ash-laden gas by-pass flue 12 of flowing through directly enters exhaust uptake 11, to realize the protection to equipment.By-pass flue 12 passes from ash bucket 14 the bag chamber 4 pre-heat effect (before deduster puts into operation) of heating, in addition, before deduster put into operation, hot-air system 15 work was also to the pre-heat effect of heating of 4 of bag chambers, during deduster work, hot-air system 15 work seal to by-pass flue 12.
The utlity model has following characteristics: 1. flue gas is through after the gas flow modulation, enters the cloth bag district in proportion from front portion, three directions in bottom and rear portion of bag chamber, and smoke distribution is reasonable and flow velocity is even; 2. the dust settling pocket chamber is adopted the sack chamber (the single chamber filter area is reached 5000M
2) and big ash bucket (single chamber list ash bucket) structure; 3. length reaches 9 meters, the fixedly connected filtration cloth bag in two ends; 4. by-pass flue passes in the middle of the ash bucket, can be before deduster puts into operation preheating dust settling pocket chamber, can save floor space again; 5. control timely break-make outlet valve and by-passing valve by temperature detection, the flue gas of avoiding too high or too low temperature is guaranteed the trouble free service of dust arrester by cloth bag; 6. make pulse jet system reliably working by detection to compressed-air actuated pressure monitor and cloth bag inside and outside differential pressure.
