Abstract
The invention relates the molded coal made with tar oil slag and breeze, comprising 15-20wt% tar oil slag, 2-6wt% breeze, 0.1-1.5wt% calcium oxide powder, 0.5-3wt% gelatinized starch, 0.05-0.3wt% polyurethane, and 70-80wt% close burning coal. The molded coal has good modeling and demoulding property, the compression strength is 150 N/ball, drop strength is 99%, and the water resistance is good. The tar oil slag is the main waste in coking workplace, and the breeze is not fully utilized. The invention has the advantages of reducing environmental pollution, saving treatment expenses, good economic benefit and environmental benefit.
Description
Technical field
The invention belongs to the waste resource recovery and utilization technology, relate to a kind of coking briquette that utilizes coke-oven plant's coke tar refuse and breeze to make.
Background technology
During the coke-oven plant produced at present, main polluting waste was a coke tar refuse, contains multiple poisonous carcinogenic substances such as benzene class, phenols, naphthalene class, has very big hazardness.As if directly effluxing or stacking, not only the section atmosphere quality can be directly influenced, and the face of land can be passed through, permeate the ground polluted underground water source, harm people's physical and mental health.So coke tar refuse belongs to danger wastes, mustn't enterprise handle privately and discharge.The method of handling commonly used at present has two kinds, and the one, directly mix freshening in the coking mixed coal, stick casing but exist, wearing and tearing and etching apparatus, problems such as severe operational environment, and because the influence of fluctuations coke quality of bulk density.Another kind method is a freshening coke behind the production moulded coal, but because coke tar refuse viscosity is big, and the volume of present production coke tar refuse is less than normal, the digestion coke tar refuse need be produced a large amount of moulded coals, causes turnout and cost too high.
The waste residue that produces during the coke-oven plant produces also includes breeze (containing the part dedusting ash), breeze be coke-oven plant's fly-ash separator collect, based on the dust of coke composition.The breeze water content is little, and powder is thin, and density is little, the transportation and the operation process very easily cause secondary pollution.Because do not have good freshening technology, the breeze major part is all mixed and burnt, do not obtain utilizing.
Summary of the invention
At the problems referred to above of the prior art, it is little to the purpose of this invention is to provide the existing coal-tar middle oil slag volume of coking briquette of a kind of solution, the processing cost height, and the breeze deficiency of not being fully used, provide a kind of prescription that utilizes the coking briquette of waste slag of coking plant production, to reduce the coke tar refuse processing cost.Mix refining after utilizing this prescription to produce moulded coal, can dispose the main waste in coke-oven plant, not only can efficiently utilize the useless coke tar refuse of coke-oven plant to make moulded coal freshening coke, and can also fully utilize the breeze of coking plant, save coal resource, meet recycling economy.The present invention also directly mixes in the coking mixed coal disadvantageous effect to equipment and product with overcoming coke tar refuse simultaneously, and produces the coke that meets technical requirements.
The technical scheme of finishing the foregoing invention task is: a kind of moulded coal that uses high volume coke tar refuse and breeze to make, and the part by weight of each component of filling a prescription is:
Coke tar refuse 15～20%, breeze 2～6%, calcium lime powder 0.1～1.5%, pasted starch 0.5%～3%, Polyurethane 0.05～0.3%, coking coal 70～80%.
Determining of breeze composition is to consider specific surface area that it can provide and in the influence of briquette strength; CaO can improve the intensity of moulded coal, and determining by coke ash and briquette strength of its composition is definite; Pasted starch can improve the cold strength of moulded coal, and Polyurethane can improve the water resistance and the cold and hot intensity of moulded coal, and pasted starch and polyamine fat components in proportions are by moulded coal water resistance and the decision of cold and hot state intensity.
The application recommends following prescription as prioritization scheme:
Coke tar refuse 15%, breeze 3%, calcium lime powder 1%, pasted starch 1%～1.5%, Polyurethane 0.1%, coking coal 79.4%～79.9%.
Coke tar refuse is the main waste that Steel Plant coking workshop produces, and breeze is the waste of failing to make full use of.The present invention carries out recycling with coke tar refuse and breeze, not only can reduce environmental pollution, saves a large amount of pollutions and handles funds, and can save the cleaned coal resource, make coke tar refuse and breeze change into coke, tar and coal gas, improve the performance of enterprises, have huge economy and environmental benefit.
Coke tar refuse is made moulded coal use, can solve coke tar refuse and directly mix in the coking mixed coal disadvantageous effect equipment and product.The moulded coal that this prescription is made, the volume of coke tar refuse improves greatly, makes the coke-oven plant can digest the depleted coke tar refuse rapidly, and the making amount of moulded coal is descended significantly, has saved a large amount of transportations and manufacturing cost.
When coke tar refuse and breeze add in the mixed coal coking separately, the heap quality product exists different influences, be made into moulded coal and mix coking coal, can utilize the different change shapes in process of coking of coke tar refuse and breeze, the part of cancelling each other detrimentally affect, combined action is guaranteed coke quality.
The moulded coal that this prescription is made, moulding and demolding performace are good, and ultimate compression strength can reach 150 Ns/ball, and dropping strength is greater than 99%, and water repelling property is good.
Adopt this prescription to produce moulded coal and allocate in the mixed coal after the coking with 5%～10% volume, become the coke strenth of output to increase, quality standard can reach the requirement of country-level metallurgical coke.
