Abstract
The invention relates to industrial air dedusting equipment and technologies, in particular to a dust collection technology and dust collection equipment for an intermediate frequency furnace. The dust collection equipment for the intermediate frequency furnace comprises a draught hood cover, a lower furnace mouth platform baffle plate and a rotating cover plate. The dust collection equipment is characterized in that the draught hood cover is arranged outside a feed port, the inner edge of the draught hood cover is connected with the outer edge of the feed port, the lower furnace mouth platform baffle plate is arranged at the bottom of the draught hood cover, the rotating cover plate is arranged in the draught hood cover, and the top of the draught hood cover is connected with a main pipeline through a bolt. By the dust collection technology and the dust collection equipment, air volume is reduced effectively, suction of primary smoke is solved, in-hood draft is increased, fan and motor capacities are reduced, and investment and operation costs are reduced effectively.
Description
Technical field
This patent relates to industrial air cleaner and technique, is specially a kind of intermediate frequency furnace control of dust Processes and apparatus.
Background technology
The version of Environmental-protecting dust-removing draught hood is directly connected to investment, operating cost, the dust removing effects of dedusting.Because now general intermediate frequency furnace draught hood adopts roof to bleed, rate of air sucked in required is owing to being subject to the impact that wild air quantity is large, and the deduster investment of rear end is large, and operating cost is high; Or adopt the mode that mobile cover side is reinforced, secondary smoke problem when hot metal charging and steel scrap can not be solved again, and flue dust problem when can not solve tapping or tap a blast furnace.
Summary of the invention
This patent is for above technical problem, and provide a kind of intermediate frequency furnace control of dust Processes and apparatus, object is effectively to decrease wild air quantity, solve the suction of a flue dust simultaneously, improve draft in cover, reduce the capacity of blower fan, motor, effectively reduce cost of investment and operating cost.
The concrete technical scheme of this patent is as follows:
A kind of intermediate frequency furnace dust-collecting equipment, be made up of shutter, rotation cover under exhausting cover cap, fire door platform, exhausting cover cap is arranged on outside charge door, exhausting cover cap inner edge is connected with reinforced peristoma, under fire door platform, shutter is arranged on bottom exhausting cover cap, arrange rotation cover in exhausting cover cap, draught hood tops and main pipeline are bolted.
A kind of intermediate frequency furnace control of dust technique:
When A, intermediate frequency furnace feed in raw material, the swivelling cover of dust-precipitating system is removed, so that blanking;
Produce negative pressure in B, blanking back cover, and high-temperature flue gas has again certain climbing power, rely on suction and climbing power that the dust of generation and flue gas are constantly inhaled in cover;
When C, tapping, rotation cover is closed, and exhausting cover cap is tumbled with stove and transferred to the region of ladle, adsorbs flue dust during tapping.
Charge door is suction opeing, effectively decreases wild air quantity, solves the suction of a flue dust simultaneously.Draught hood and fire door flapper gap minimize, and improve draft in cover.Tap a blast furnace (steel) time, charge door rotation cover seals, and increases the suction of secondary smoke.By above structure, reduce the capacity of blower fan, motor, effectively reduce cost of investment and operating cost.
The invention has the beneficial effects as follows: a, this draught hood and main pipeline, for removably connecting, are convenient to the maintenance of intermediate frequency furnace; The flue gas that the structure of b, this draught hood solves charge door enters cover problem, has effectively taken a flue dust away; C, because charge door and furnace port diameter are axially overlapping completely, exhausting area is little, considerably reduces exhausting amount, and the equipment investment of rear end significantly reduces; When d, tapping (iron), charge door is closed, and suction opeing is tumbled with stove and transferred to the region that steel (iron) wraps, and ensure that the extraction of tapping (iron) flue dust.
Accompanying drawing explanation
Fig. 1 is this patent structural representation.
Wherein, 1---exhausting cover cap, 2------rotation cover, 4---charge door, the 5---main pipeline of shutter, 3 under fire door platform.
Detailed description of the invention
Below in conjunction with specific embodiment, this patent is described further.
A kind of intermediate frequency furnace dust-collecting equipment, be made up of shutter, rotation cover under exhausting cover cap, fire door platform, exhausting cover cap is arranged on outside charge door, exhausting cover cap inner edge is connected with reinforced peristoma, under fire door platform, shutter is arranged on bottom exhausting cover cap, arrange rotation cover in exhausting cover cap, draught hood tops and main pipeline are bolted.Main pipeline extends connecting fan pump.
A kind of intermediate frequency furnace control of dust technique:
When A, intermediate frequency furnace feed in raw material, the swivelling cover of dust-precipitating system is removed, so that blanking;
Produce negative pressure in B, blanking back cover, and high-temperature flue gas has again certain climbing power, rely on suction and climbing power that the dust of generation and flue gas are constantly inhaled in cover;
When C, tapping, rotation cover is closed, and exhausting cover cap is tumbled with stove and transferred to the region of ladle, adsorbs flue dust during tapping.
Charge door is suction opeing, effectively decreases wild air quantity, solves the suction of a flue dust simultaneously.Draught hood and fire door flapper gap minimize, and improve draft in cover.Tap a blast furnace (steel) time, charge door rotation cover seals, and increases the suction of secondary smoke.By above structure, reduce the capacity of blower fan, motor, effectively reduce cost of investment and operating cost.
