The primary dust remover is characterized in that a first dust removing baffle is arranged in the position from the dust remover inlet to a cavity inlet of the dust remover body, a second dust removing baffle is arranged in the position from a cavity outlet to an entrance of the dust remover outlet, and more than 80%-90% of solid particulate matters in the high-temperature gas are blocked into the collecting unit at the lower end of the dust hopper after the high-temperature gas passes by the first dust removing baffle and the second dust removing baffle. By means of the structure, discharge of gas is not influenced under the condition that dust removing force is enhanced, so that the secondary treating difficulty is decreased.
Description
Technical field
The present invention relates to a kind of dry coke quenching fly-ash separator, particularly a kind of cork dry quenching disposable dust remover.
Background technology
Dry coke quenching is to adopt rare gas element by a kind of cooling method of red Jiao, in dry coke quenching process, red Jiao packs into from the dry furnace roof portion of putting out, and wind just low temperature rare gas element circulation blasts dry putting out in the red burnt layer of stove cooling room, absorb red burnt heat, cooled coke is discharged from the dry furnace bottom that puts out.From the dry stove ring-shaped flue high temperature inert gas out of putting out, entering heat exchange system, carry out dust removal process, so that while re-using, can not pollute postorder system.
Carry out dust removal process and will carry out twice processing, one-time dedusting and final dusting that Here it is often says.
Existing one-time dedusting is that high temperature inert gas is entered after disposable dust remover entrance, first enter high-temperature expansion joint, then by disposable dust remover gravitational dust collection baffle plate, after gas gravitational dust collection baffle plate, gas rises to disposable dust remover outlet after walking around gravitational dust collection baffle plate, the red coke powder body of gravity enters the ash bucket of bottom, treated to the collection of coke breeze collection device, is transported to next process.
Owing to adopting simple primary treatment, due to the existence of high temperature inert gas pressure, still have a large amount of red coke powder bodies to outlet, increased the difficulty of secondary treatment.
Summary of the invention
The object of this invention is to provide the cork dry quenching disposable dust remover that a kind of efficiency of dust collection is high.
The object of the present invention is achieved like this, a kind of cork dry quenching disposable dust remover, which comprises at least: fly-ash separator body, fly-ash separator body top one side is fly-ash separator entrance, opposite side is fly-ash separator outlet, fly-ash separator entrance and fly-ash separator outlet are separately installed with high-temperature expansion joint, the dedusting chamber of fly-ash separator entrance and fly-ash separator outlet lower end is for falling " Eight characters " structure, there is ash bucket the lower end, dedusting chamber of " Eight characters " structure, the lower end of ash bucket is collector unit, collector unit is for collecting the solid particulate matter of high temperature inert gas, it is characterized in that: fly-ash separator entrance has the first dedusting baffle plate to the cavity ingress of fly-ash separator body, cavity outlet has the second dedusting baffle plate to the ingress of fly-ash separator outlet, high-temperature gas is after the first dedusting baffle plate and the second dedusting baffle plate, the solid particulate matter that is greater than 80%-98% is kept off into the collector unit of ash bucket lower end.
The first described dedusting baffle plate is in first upper end, inclined-plane of falling " Eight characters " structure, and the second dedusting baffle plate is in second upper end, inclined-plane of falling " Eight characters " structure.
The waviness on the first described inclined-plane is greater than the waviness on the second inclined-plane.
The present invention is owing to adopting two-stage dirt baffle plate, and dedusting chamber is for falling " Eight characters " structure, and the waviness on first inclined-plane of " Eight characters " structure is greater than the waviness on the second inclined-plane.This structure in the situation that strengthening dedusting dynamics, the discharge of not losing gas.Reduced the difficulty of secondary treatment.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the present invention is specifically described:
Fig. 1 is embodiment of the present invention structural representation.
In figure, 1, fly-ash separator body; 2, fly-ash separator entrance; 3, fly-ash separator outlet; 4, the first dedusting baffle plate; 5, pressure excretion end; 6, ash bucket; 7, collector unit; 8, the second dedusting baffle plate; 9, the first inclined-plane; 10, the second inclined-plane; 11, high-temperature expansion joint.
Embodiment
A kind of cork dry quenching disposable dust remover, which comprises at least: fly-ash separator body 1, fly-ash separator body 1 top one side is fly-ash separator entrance 2, opposite side is fly-ash separator outlet 3, fly-ash separator entrance 2 and fly-ash separator outlet 3 are separately installed with high-temperature expansion joint 11, fly-ash separator entrance 2 and fly-ash separator export the dedusting chamber of 3 lower ends for falling " Eight characters " structure, there is ash bucket 6 lower end, dedusting chamber of " Eight characters " structure, the lower end of ash bucket 6 is collector units 7, collector unit 7 is for collecting the solid particulate matter of high temperature inert gas, it is characterized in that: fly-ash separator entrance 2 has the first dedusting baffle plate 4 to the cavity ingress of fly-ash separator body 1, cavity outlet has the second dedusting baffle plate 8 to the ingress of fly-ash separator outlet, high-temperature gas is after the first dedusting baffle plate 4 and the second dedusting baffle plate 8, the solid particulate matter that is greater than 80%-98% is kept off into the collector unit 7 of ash bucket 6 lower ends.
