Abstract
The invention relates to a process for re-preparing the coking waste of dry coke powder and wet coke powder in a coking plant. The process comprises the following steps: (1) a working procedure of mixing the dry coke powder and the wet coke powder, during which according to proportion, the dry coke powder enters to a dry and wet material blender through a speed regulation rotary valve; the wet coke powder with water content of between 40 and 45 weight percent enters the dry and wet material blender through the transportation of a 1<*> number belt conveyer; and the dry coke powder and the wet coke powder are evenly mixed to obtain a coke powder mixture with the water content of less than or equal to 10 weight percent; and (2) a working procedure of adding the coke powder, during which the coke powder mixture is transported to a middle feed bin through a serpentiform conveyer; according to the requirement of the re-preparing amount, the coke powder mixture enters a 3 <*> number belt conveyer through a speed regulation spiral conveyer and is transported to a working procedure of coking. The process solves the problem of comprehensive utilization of the dry coke powder and the wet coke powder of the coking waste, makes waste profitable, saves energy, improves the environmental and sanitary conditions of the coking plant and increases economic benefit.
Description
Technical field
The present invention relates to the technical process of dried coke powder of a kind of waste material and wet coke powder blending device, specifically, the allotment of labor that returns who relates to a kind of dried coke powder of coke-oven plant's coking waste material and wet coke powder plants.
Background technology
In the Coking and Gas production process of daily coke-oven plant, will produce some dried coke powders, obtain by the fly-ash separator gathering system.Wet coke powder is that pit kiln adopts wet dedusting to be disposed in the settling tank, through grab crane will wet coke powder pick up in the pond stack spill dried.The wet coke powder water ratio that spills after doing is 41.7 weight %, and is original, adopts the take-away method to handle dried coke powder and wet coke powder, still, along with the marketization of commodity, does, the take-away of wet coke powder handles and have certain difficulty and influence environmental protection.In order in factory, to solve the problem of outlet of useless coke powder, the present inventor has designed and will do, wet coke powder according to a certain percentage, be blended in the raw coal as the coking raw material, return the novel process of joining utilization.
But, because dried coke powder when under the situation of humidification not, transporting, adding on the endless belt conveyor of coking process, can cause dust from flying, cause the secondary pollution of plant area, can not reach the purpose of utilization; And wet coke powder (water ratio 41.7 weight %) when intermediate bunker is stored and carry, can produce the putty phenomenon though can not cause dust from flying.
Summary of the invention
Recycle problem in order to solve dried coke powder of coking plant waste material and wet coke powder, overcome defective of the prior art, what the invention provides a kind of environmental protection, energy-conservation dried coke powder and wet coke powder returns allotment of labor's skill.Through test, determined the proper state and the physical data of material to be processed, earlier dried coke powder and wet coke powder are carried out the compound that thorough mixing obtains water ratio≤10 weight %, and then solve the normal problem of joining utilization of carrying, store and return.
The present invention is achieved in that dried coke powder of this coking waste material and wet coke powder and returns allotment of labor's skill and comprises that the mixed processes of (1) dried, wet coke powder and (2) coke powder add operation.
(1) do wet coke powder mixed processes:
Dried coke powder enters dried, wet feed mixing machine from dried coke powder feed bin in proportion through push-pull valve and speed governing rotary valve; Water ratio is that the wet coke powder of 40～45 weight % is delivered to discharging hopper by shovel loader, through 1
*Number endless belt conveyor is carried, and enters dried wet feed mixing machine in proportion, does, wet coke powder is through mixing, and obtains the coke powder compound of water ratio≤10 weight %, through 2
*Number endless belt conveyor is transported to interim stockyard.
(2) coke powder adds operation
The coke powder compound is delivered to the buffering feed bin through shovel loader, through push-pull valve by snakelike conveyor delivery to intermediate bunker, the coke powder compound in the intermediate bunker is pressed back the needs of dosage by the speed governing worm conveyor, after the verification of swash plate type under meter, enters 3
*Number endless belt conveyor is transported to coking process.
The discharging hopper both sides are provided with the oscillating plate motor in the mixed processes of the present invention, at discharge opening place, discharging hopper bottom vane-type stepless speed regulation arch breaking apparatus are set.
In the intermediate bunker in the coke powder interpolation operation of the present invention air bubble arch breaking apparatus and vertical broken arch feeding device are set.
It is 2 tons/hour～20 tons/hour that the coke powder of the speed governing worm conveyor in the coke powder interpolation operation of the present invention is carried back the dosage regulation range.
The coke powder that coke powder of the present invention adds the speed governing worm conveyor in the operation carries back the dosage regulation range to be preferably 2 tons/hour, 4 tons/hour, 6 tons/hour, 8 tons/hour, 10 tons/hour or 20 tons/hour.
Mixed processes mainly solves the mixed problem of dried, wet coke powder among the present invention, adds conveying, storage that operation mainly solves compound, returns problems such as joining metering.
Among the present invention in the mixed processes technical process key equipment be discharging hopper and do, the wet feed mixing machine.The both sides of discharging hopper are provided with the oscillating plate motor.The arch breaking apparatus of vane-type stepless speed regulation is set at the discharge opening place of discharging hopper bottom, has solved wet coke powder (water ratio＜41.7 weight %) and tied the problem of encircleing with the discharging hopper headwall.Owing to adopt aforesaid device, guaranteed that wet coke powder enters endless belt conveyor by discharging hopper smoothly.Do, the effect of wet feed mixing machine dried, the wet mixing machine that is that (1) dried coke powder and wet coke powder enter according to a certain ratio.(2) in doing, wetting mixing machine, the coke powder of doing, wet need mix, and makes dried, wet compound can send defeated continuously, uniformly forward.
The present invention adds that key equipment is intermediate bunker and speed governing worm conveyor in the operation.The structure of intermediate bunker mainly solves compound and bulkhead knot arch problem and the reinforced problem of even successive, air bubble arch breaking apparatus and vertical broken arch feeding device are set in the intermediate bunker, guarantee compound feeding uniformly continuously in feed bin, material is wall built-up not, can regulate the dosage of returning of material arbitrarily, the speed governing worm conveyor mainly solves the conveying of coke powder compound and returns the adjusting problem of dosage, and it is 2 tons/hour, 4 tons/hour, 6 tons/hour, 8 tons/hour, 10 tons/hour or 20 tons/hour that coke powder is carried back the dosage regulation range.
The present invention has following tangible advantage:
One, solved the problem of complex utilization of dried coke powder of coking waste material and wet coke powder preferably, turned waste into wealth, can save raw coal more than 3000 tons in 1 year, save energy is increased economic efficiency.
Having solved wet coke powder carries and mixing transportation problem dried, warm coke powder at the discharging hopper inner broken arch.
Three, solved compound and do not tie arch in intermediate bunker, evenly problems such as operational throughput are regulated in conveying and stepless change continuously.
Four, improve on-site environment and sanitary condition greatly, prevent the infringement of flyash, improve the worker health level worker's health.
