Description
Technical field
The invention belongs to the dust collecting process apparatus field, particularly a kind of spiral cylinder cyclone dust collecting process apparatus is applicable to waste gas, the flue gas ash removal of the large, medium and small industrial and mining enterprises of blast furnace and so on production equipment.
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 being used to generate the very close air velocity that increased of swirl vane, this is unfavorable for improving dust removing effects on the other hand.The axial transport conveyor constructions complexity here, specification requirement is very high.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, the spiral cylinder cyclone dust collecting process apparatus that efficiency of dust collection is high.
According to spiral cylinder cyclone dust collecting process apparatus of the present invention, comprise exhaust inlet pipe, blast pipe, flue-dust retainer, cyclone separating chamber, it is characterized in that described 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 that is positioned at the spiral tube of cyclone separator upper end connects, and is provided with air-flow current limliting dust suppression device in cyclone separating chamber's bottom trapezoidal sections.
Have individual along equally distributed 8 the spiral tubes of circumference in inside, described spiral wind separation chamber.
Described current limliting dust suppression device is a truncated cone-shaped, is provided with grey gap at the bottom of the round platform and between the sidewall of cyclone separating chamber.
The following sidewall of spiral tube outlet of described cyclone separating chamber is provided with the wear-resistant material layer that is made of wear-proof metal ceramic.
Adopt spiral cylinder cyclone dust collecting process apparatus of the present invention, waste gas (for example blast furnace gas) is introduced the gas collection distributor chamber from air inlet pipe, this distributor chamber is sent gas respectively in each spiral tube, under the guiding of spiral tube, gas is around the axis rotation of cyclone separating chamber, and under action of centrifugal force, the grit in the waste gas is thrown to the sidewall of cyclone separating chamber, glide along sidewall then, the gap between cyclone separating chamber's limit wall and round platform falls into flue-dust retainer.Whirlwind runs into and turns to behind the round platform uply, enters blast pipe and enters upstream device.
The advantage of this spiral cylinder cyclone dust collecting process apparatus is:
1, waste gas volume when air inlet pipe enters the gas collection distributor chamber enlarges and causes air velocity to reduce, and the air velocity in the general blast furnace gravitational dust collection process equipment is 14～20m/s.And the wind speed that enters spiral tube of the present invention drops to 9～14m/s.Air velocity is low, and dust removing effects has improved.Prove that through simulated test efficiency of dust collection of the present invention is up to 85～95%, the force of gravity deduster raises the efficiency 40%.
2, since waste gas when the pressure distribution chamber enters the spiral tube, airflow direction is slowly, changes gradually, this has just greatly reduced the impulsive force of air-flow to the spiral barrel, thereby has reduced the wearing and tearing of spiral tube.
3, because medium flows with lower speed, and direction is sharply variation not, and the flue dust in the air-flow is not separated, and is therefore less to the wearing and tearing of barrel, prolonged the service life of equipment in whirlwind spiral tube.
4, because the cyclone separating chamber bottom is provided with truncated cone-shaped current limliting dust suppression device, air-flow turns at this, separated dust is subjected to stopping of round platform, drop in the flue-dust retainer fully, and air-flow rotates up air inlet-outlet pipe, so air-flow rotates up because of being obstructed, also prevented because of the secondary dust that impact caused of air-flow simultaneously flue-dust retainer.
