Description
Technical field
The present invention relates to coking technology, more particularly to a kind of processing method of coking coal processing tar slag dust-removing powder.
Background technology
In coking production, coal handling system mainly includes the links such as cooperation, crushing and transhipment of coal, in the process not
Coal dust can be avoided the occurrence of.In order to reduce the pollution of field operation team environment, improve production operation condition, pulverizing chamber, each turn
The points such as fortune station set exhaust dust device with bag, eliminate a large amount of dust generated in the process.The dust that each dust point generates is by ventilation blower
Through air-suction cover and pipeline sucking ground dedusting device, purified in sack cleaner, air is discharged into after the air of purification is up to standard.Cloth
The dust that bag is collected is transported to humidifier by scraper plate, humidifies on heel row to belt conveyor, directly returns to transporting coal system.
During similary belt conveyor conveying coal, the problem of material material is a general character is scattered, reason is also many；
It is currently mostly to clean to collect to miscellaneous Coal Stack Yard or directly return system；The former had not only polluted environment but also waste of resource, and the latter is difficult to
Man-computer cooperation is avoided to injure, there are very big security risks.
In actual coking production, typically the tar slag of mechanical settling tank discharge is sent to after the collection of slag case
The tar slag bath of coal yard is stacked or undersold as fuel；In order to mitigate environmental pollution, the factories such as Baosteel, Wuhan Iron and Steel Plant are in the future
The tar slag chute stretched machine feeding and set is carried by monobucket with fork truck from the tar slag of tar slag defecator, via electro-hydraulic dynamic tablet
Gate controls flow, is directly appended to by Belt Conveying come in coal, road is handled after progress.
It is progressively plus tight and coking coal resource in short supply with national environmental standard and requirement, at current this coking coal
Dust-removing powder, coal breakage and the tar slag of coking process problem also highlight further in reason system, major embodiment the following aspects：
Dust-removing powder in coal handling system, generally by being directly appended to coal belt conveyor nearby after humidification, due to dust-removing powder
Granularity is smaller, and with addition shipwreck to merge, easily airborne dust in adding procedure causes serious secondary pollution.
Tar slag is a kind of thick industrial solid wastes generated in coke-oven plant's production process, contains benzene class, phenols
Etc. a variety of toxic components, and easily there is evaporating, emitting, dripping or leaking of liquid or gas scene in additive transmission process in this tar slag adding technology, along transport
And Adding Area environmental pollution is serious, it is impossible to meet current environmental requirement.
Tar slag is difficult to control containing dilutional hyponatremia, and bonding of the aggravation cinder mixture on ribbon conveyer is easily damaged defeated
Send equipment.
The content of the invention
It is an object of the invention to provide a kind of processing method of coking coal processing procedure dust-removing powder, by dust-removing powder, recycling
Coal breakage, tar slag etc. are conveyed into tank, and after quantitatively cutting out, compacting balling-up returns to coal delivery system, to put forth effort to reduce environment dirt
Dye, preferably utilizes potential resource.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of processing method of coking coal processing procedure dust-removing powder, comprises the following steps：
1) by coking coal processing respectively except dirt pits ash cellar dust-removing powder is by Geldart-D particle, into medial launder；
2) coking coal processing region coal breakage, by Belt Conveying to the medial launder after collection, belt conveyor sets to go
Deimpurity metal detector, electric magnetic iron remover；
3) after coking output tar slag is cleaned, by being pumped into tar slag medial launder；
4) dust-removing powder, miscellaneous coal and tar slag are quantitatively cut out, by mixing, stirring evenly, by Belt Conveying to two pairs of rollers into
Type machine is pressed into the coal briquette of certain size size, and coal tower is delivered to through belt.
Preferably, the Geldart-D particle i.e. conveyance conduit beginning at ash cellar is continuously added to quantitative compressed air or nitrogen
As the carrier of conveying dust-removing powder, dust-removing powder is transported to from the storehouse that sends of conveyance conduit and receives the medial launder of dust-removing powder.
Preferably, tar slag pipeline of the tar slag in transportational process, tar slag medial launder, screw feeder equipment, mixing
Stirring and former need to set steel insulation jacket, are passed through steam, prevent tar slag solidification from causing system jams.
Beneficial effects of the present invention：
Use the coking coal processing procedure dust-removing powder processing method of the present invention, scientific and reasonable digestibility and utilization industrial dedusting
The industrial residues such as powder, coal breakage and tar slag, effective recovery of three wastess(waste gas,waste water and industrial residue) had both solved the problems, such as industrial pollution Reasonable Protection environment；
Resource-effective coking coal raw material is made full use of again, reduces production cost, improves the efficiency of cycling economy of enterprise.
Description of the drawings
Fig. 1 is the process flow chart of coking coal processing procedure dust-removing powder processing method of the present invention.
Specific embodiment
Referring to Fig. 1, a kind of processing method of coking coal processing procedure dust-removing powder of the invention comprises the following steps：
1) coking coal processing is respectively buffered except 1 dust-removing powder of dirt pits ash cellar enters by drag conveyor 2, bucket elevator 3
Storehouse 4, then by Geldart-D particle, into medial launder 5；
2) coking coal processing region coal breakage passes through 6 Belt Conveying of ribbon conveyer to the medial launder 5, conveying after collection
Belt sets to remove deimpurity metal detector, electric magnetic iron remover；
3) after coking output tar slag is cleaned, by being pumped into tar slag medial launder 7；
4) dust-removing powder, miscellaneous coal and tar slag are quantitatively cut out, is conveyed respectively by ribbon conveyer 6 ', screw feeder equipment 8
To double worm mixer 9, through mixing, stir evenly, then roller briquetting machine 11 is delivered to by ribbon conveyer 10 and is pressed into centainly
The coal briquette of size is directly delivered to coal tower 13 by ribbon conveyer 12.
In the present embodiment, the Geldart-D particle i.e. conveyance conduit beginning at ash cellar is continuously added to quantitative compressed air
Or carrier of the nitrogen as conveying dust-removing powder, dust-removing powder is transported to from the storehouse that sends of conveyance conduit and receives the centre of dust-removing powder
Slot.
Tar slag pipeline of the tar slag in transportational process, tar slag medial launder, screw feeder equipment, be mixed and
Former needs to set steel insulation jacket, is passed through steam, prevents tar slag solidification from causing system jams.
It, can be in the case where influencing little feelings to coal blending quality and coke quality using the method for the present invention, scientific and reasonable digestion
Industrial " three Waste " had both solved the problems, such as industrial pollution Reasonable Protection environment；Resource-effective coking coal raw material is made full use of again, is reduced
Production cost improves the efficiency of cycling economy of enterprise.
Coking coal processing procedure dust-removing powder processing method of the present invention, applicable and all coking coal handling systems, therefore
With preferable promotional value and practical value.
