Description
Technical field
The utility model relates to the industrial dedusting technical field, and particularly a kind of efficient wear-proof drum type cyclone dust collector is particularly useful for main equipment primary dust removings such as blast furnace.
Background technology
Dedusting equipment has a variety of, and cyclone dust collecting process apparatus is wherein a kind of, and dedusting of blast furnace gas requires very high to cleaner, and conventional cyclone dust collecting process apparatus is difficult to meet the demands.Application for a patent for invention 00802241.0 discloses a kind of " dust extraction installation for blast furnace gas ", comprise a large-scale cyclone separator, a vertical pressurized canister is arranged, be connected with axial conveying device on being positioned at pressurized canister from the blast furnace gas pipeline of blast furnace, the swirling device that has guide vane is located at the below of axial conveying device, make the axis rotation of installation for blast furnace gas around the compression chamber, centrifugal force is thrown to the particle in the installation for blast furnace gas cylindrical outer wall of balancing gate pit, then along sliding in the flue-dust retainer under the outer wall, air-flow then upwards turns at bottom skew Zhong Chu and enters the central outlet pipe, discharge deduster, this dust arrester is provided with the very complicated axial conveying device of structure, the guide vane of swirl-flow devices is that 15～30 ° of angle lappings tiltedly are provided with, guide vane can reach 30, and gas impacts guide vane vertically downward from axial conveying device, and this has aggravated the wearing and tearing of guide vane on the one hand, owing to the very close air velocity that increased of blade that is used to generate eddy flow, this is unfavorable for improving dust removing effects on the other hand.The axial transport conveyor constructions complexity here, specification requirement is very high.
Application for a patent for invention 2005100733041 " spiral cylinder cyclone dust collecting process apparatus ", comprise exhaust inlet pipe, blast pipe, flue-dust retainer, cyclone separating chamber, be characterized in that the cyclone separating chamber upper end is connected with exhaust inlet pipe by a pressure distribution chamber, cyclone separating chamber's internal upper part is provided with along equally distributed 6～12 the spiral tubes of circumference, suitable for reading and the circumferential apertures pressure distribution chamber of spiral tube connects, be provided with air-flow current limliting dust suppression device in the trapezoidal sections of bottom, inwall has high-abrasive material.Air-flow forms low speed, stable, thin layer eddy flow under the effect of spiral tube, centrifugal force can more effectively be separated dust from air-flow.Air velocity in the spiral tube of this deduster is lower, and airflow direction is reasonable, and impulsive force is little, and the degree of wear is low, the efficiency of dust collection height, and integral device is simple in structure, is applicable to the waste gas dedusting of the big-and-middle-sized industrial and mining enterprises of blast furnace and so on equipment.
Practical probation finds that this cleaner also has some places that have much room for improvement: the indoor distribution of air flow of pressure distribution is reasonable inadequately, and outer wall still has more serious wearing and tearing; Cyclone separating chamber's limit wall wearing and tearing are inhomogeneous, and to the trapezoidal sections bottom, it is serious more to wear and tear more, and this is because of the bottom cone, piles up a large amount of dust, along with air-flow rotates repeatedly, causes the wearing and tearing repeatedly of opposite side wall, and the making of spiral tube, installation are all convenient inadequately.
The dust separation chamber of cyclone dust collectors up to now all is the monotubular formula, studs with abrasion-proof backing block on the indoor sidewall of centrifugation, improving wearability, but still is ground away unavoidably or worn out, causes dust pelletizing system to stop production.And the complex process of lining plate, cost is also high.
Summary of the invention
