Abstract
The invention discloses an efficient dedusting device in special steel processing. The efficient dedusting device in special steel processing comprises a cyclone deduster (2), a bag-type deduster (4), a bin wall vibrator (6) and a main support (9); the upper part of the cyclone deduster (2) is provided with a flue channel (1), and the bottom of the cyclone deduster (2) is provided with a cyclone deduster ash removing opening (10). The efficient dedusting device in special steel processing is characterized in that the cyclone deduster (2) and the bag-type deduster (4) are fixed on the main support (9) by a connecting flue channel (3); flue gas enters the cyclone deduster (2) for primary dedusting by the flue channel (1), and then enters the bag-type deduster (4) for secondary dedusting by the connecting flue channel (3). According to the invention, the dedusting effect in secondary dedusting reaches 99% above; by virtue of the temperature reduction effect on flue gas by a water jacket, the dedusting efficiency is improved, and the service life is prolonged; through a blowback system, dust can be cleaned out from an ash removing opening easily. Compared with a traditional bag-type deduster, the service life of the efficient dedusting device is prolonged by at least one time.
Description
Technical field
The present invention relates to a kind of cleaner, particularly a kind of for processing the high effect dust cleaner of special steel.
Background technology
The process of steel-making, essence is by the carbon in molten iron and a small amount of phosphorus thereof, silicon, the process that the elements such as sulphur are oxidized, in this course, produce a large amount of carbon monoxide, the high-temperature gas of carbon dioxide and other composition, and carrying a large amount of iron oxide secretly, metallic iron forms a large amount of brownish red dense smoke with the tiny solid flue dust of other particle, these dense smoke effectively can be collected, disposal and utilization, and discharge clean harmless gas in atmosphere, whether a steel mill has sustainable development capacity, whether there is international competitiveness, the important symbol that even whether to have survival ability.For many years, many steel mills are attached great importance to efforts at environmental protection, and the improvement of dust pelletizing system has been descended to the very large time.At present most steel mill adopts the mode of bag-type dust, and general resistant to elevated temperatures bag-type dust removal system investment is large, and efficiency of dust collection is low, and system stability is poor.As a small-sized steel-making enterprise, a large amount of fund inputs, in dust pelletizing system, can cause very large investment risk.Therefore, develop a kind of dust pelletizing system of making steel efficiently, cheaply, for environmental protection and enterprise development, have great importance.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of high effect dust cleaner of processing special steel, low-cost, efficient dust pelletizing system, reaches efficiency of dust collection 99% the above object.
The technical solution used in the present invention is: a kind of high effect dust cleaner of processing special steel, comprise cyclone dust collectors, sack cleaner, hopper wall vibrator and main support, the top of cyclone dust collectors is provided with flue, bottom is provided with cyclone dust collectors ash disposal mouth, it is characterized in that: described cyclone dust collectors are fixed on main support by being connected flue with sack cleaner, flue gas enters cyclone dust collectors one-time dedusting by flue, then enters sack cleaner and carry out final dusting by connecting flue.
Described flue is outside equipped with water jacket, and the water heating in water jacket is entering cyclone dust collectors cooling for flue gas, can effectively improve the efficiency of deduster;
The middle part of described cyclone dust collectors is also provided with blowback system, when having accumulated a large amount of dusts in deduster, opens blowback system, and dust can be discharged from the cleaning door of cyclone dust collectors fast;
On described sack cleaner, be provided with hopper wall vibrator, the vibrations of hopper wall vibrator, remove the dust in sack cleaner.
Structure of the present invention, final dusting, dust removing effects reaches more than 99%, cooling effect by water jacket to flue gas, greatly improved the service life of efficiency of dust collection and the sack cleaner of deduster, by blowback system, can easily dust have been cleared up away from cleaning door.The present invention compares with traditional sack cleaner, and the life-span is more than doubled, and efficiency of dust collection improves more than 10%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 flue, 2 cyclone dust collectors, 3 connect flue, 4 sack cleaners, 5 observation panels, 6 hopper wall vibrators, 7 outlet flues, 8 sack cleaner ash disposal mouths, 9 main supports, 10 cyclone dust collectors ash disposal mouths, 11 blowback systems.
The specific embodiment
By Fig. 1, known, a special steel processing high effect dust cleaner, is comprised of flue 1, cyclone dust collectors 2, connection flue 3, sack cleaner 4, observation panel 5, hopper wall vibrator 6, outlet flue 7, sack cleaner ash disposal mouth 8, main support 9, cyclone dust collectors ash disposal mouth 10 and blowback system 11.The top of cyclone dust collectors 2 is provided with flue 1, and bottom is provided with cyclone dust collectors ash disposal mouth 10, cyclone dust collectors 2 be fixed on main support 9 by being connected flue 3 with sack cleaner 4.Flue gas enters cyclone dust collectors 2 by flue 1, by the one-time dedusting of cyclone dust collectors 2, removes particle more than 80% above 5-15 micron.By sack cleaner 4 final dustings, remove more than 99% particle.Finally the flue gas that reaches emission request is discharged in atmosphere by outlet flue 7.Described flue 1 is outside equipped with water jacket, and when flue gas is by flue 1 time, the water in water jacket is heated, and flue gas is before entering cyclone dust collectors 2, and temperature obtains very large reduction, can effectively improve the efficiency of dust collection of deduster.
On described cyclone dust collectors 2, be also provided with blowback system 11, when having accumulated a large amount of dusts in deduster, open blowback system 11, dust can be discharged from the cleaning door 10 of cyclone dust collectors fast;
On described sack cleaner 4, be provided with hopper wall vibrator 6, when sack cleaner is after 4 work a period of times, the dust accumulating on cloth bag is by the shock effect of hopper wall vibrator 6, and the dust that sack cleaner is 4 li can be discharged from sack cleaner cleaning door 8 fast;
On described sack cleaner 4, be also provided with observation panel 5, by observation panel 5, can check deduster internal work situation, simultaneously can be for changing dust-removal cloth-bag.On described sack cleaner, be also provided with observation panel, by observation panel, can check deduster internal work situation, simultaneously can be for changing dust-removal cloth-bag.
