Abstract
The invention discloses a novel deduster dust discharging method. According to the novel deduster dust discharging method, advanced control methods including discharging potential difference control, discharge outlet negative pressure control, and uniform blanking control are adopted. The novel deduster dust discharging method is low in cost, and is convenient to realize; inhibiting effect on reentrainment of dust is excellent; and performance-cost ratio is extremely high.
Description
Technical field
Grey mode is unloaded the present invention relates to a kind of innovative deduster, it is adaptable to field of operation.
Background technology
The dust that deduster is collected generally wants communicated band conveying or Geldart-D particle or is loaded into transport vehicle conveying, returns to raw material system or outward transport.Wherein, conveyer belt and pneumatic conveying mode are applied to apart from the region of destination relative close；More long for fed distance is particularly and is transported between different plant areas, then generally use transport vehicle mode of movement.From deduster ash silo cinder-discharging port to transport vehicle unload ash during, the problem that presently, there are is seriously polluted reentrainment of dust, causes to unload ash point environment poor.At present.Avoiding the measure of reentrainment of dust has various, for example：To concentrating ash silo cinder-discharging port to seal；Dust shield is set ash point is unloaded, pipe network is accessed by pipeline；Dedusting ash loads and unloads pot type Automobile Transportation using pneumatic powder；Using humidifier；Using dust-free loader etc., this several ways respectively has advantage and disadvantage.
The content of the invention
The present invention proposes a kind of innovative deduster and unloads grey mode, not only low cost, easily implements, and suppresses that the effect of reentrainment of dust is good, and the ratio of performance to price of can yet be regarded as is very high to unload grey mode.
The technical solution adopted in the present invention is：
It is described to unload grey mode and be：After drawing grey car in place, hoist engine is opened, decline trapping sleeve to car bottom.Star-shaped dust-discharging valve is opened, dust falls in car bottom from concentrating ash silo to fall along inner sleeve.As dust more heap is more.Progressively crawl hoist engine lifting traps sleeve.Unload space of the reentrainment of dust produced during ash between inner sleeve and outer sleeve.A nearest air-intaking bent pipe of people's deduster is inhaled along thin pipe, deduster filtering is reentered.Meanwhile, trapping sleeve can not only be controlled to lift by hoist engine.And can be swung along car length direction by Electrohydraulic push rod control, the purpose of uniform blanking is on the one hand played, on the other hand play a part of material toggling, effectively reduce the slope top of dust heap.In addition, compared with dust-free loader, unload that grey speed is fast, and star-shaped dust-discharging valve transporting velocity synchronization.
It is described to unload grey mode using the control of discharging potential difference, the lifting of feed opening is controlled by hoist engine, discharging potential difference is reduced, it is economical and practical.
It is described to unload grey mode using discharge port vacuum cavitations, internal and external casing is set, inner sleeve blanking, the space between internal and external casing is connected at air-intaking bent pipe the negative pressure for forming discharge port by pipeline, it is to avoid reentrainment of dust diffusion, and dust pelletizing system filtering is sucked again.
Described to unload grey mode using the control of uniform blanking, during dust falls, the swing for trapping sleeve realizes uniform blanking of the dust in whole compartment.
The beneficial effects of the invention are as follows：This unloads grey mode low cost, makes simple, and easy to operate, maintenance is small, applied widely.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is of the invention to unload grey mode principle schematic.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, after drawing grey car in place, hoist engine is opened, decline trapping sleeve to car bottom.Star-shaped dust-discharging valve is opened, dust falls in car bottom from concentrating ash silo to fall along inner sleeve.As dust more heap is more.Progressively crawl hoist engine lifting traps sleeve.Unload space of the reentrainment of dust produced during ash between inner sleeve and outer sleeve.A nearest air-intaking bent pipe of people's deduster is inhaled along thin pipe, deduster filtering is reentered.Meanwhile, trapping sleeve can not only be controlled to lift by hoist engine.And can be swung along car length direction by Electrohydraulic push rod control, the purpose of uniform blanking is on the one hand played, on the other hand play a part of material toggling, effectively reduce the slope top of dust heap.In addition, compared with dust-free loader, unload that grey speed is fast, and star-shaped dust-discharging valve transporting velocity synchronization.
Unload grey mode to be controlled using discharging potential difference, the lifting of feed opening is controlled by hoist engine, reduce discharging potential difference economical and practical.
Grey mode is unloaded using discharge port vacuum cavitations, internal and external casing is set, inner sleeve blanking, the space between internal and external casing is connected at air-intaking bent pipe the negative pressure for forming discharge port by pipeline, it is to avoid reentrainment of dust diffusion, dust pelletizing system filtering is sucked again.
Unload grey mode to be controlled using uniform blanking, during dust falls, the swing for trapping sleeve realizes uniform blanking of the dust in whole compartment.
