Abstract
The invention discloses high-density sludge slurry and preparing method, which comprises the following parts: 100-200wt% coal powder, 10-50wt% sludge with water, 10-100wt% water, 1-5wt% water, 1-5wt% addictive and 1-5wt% sludge modifying agent.
Description
Technical field
The present invention relates to a kind of sludge coal slurry and preparation method thereof.
Background technology
Coal water slurry is the novel coal based fluid fuel of a kind of replace oil with coal of rising behind the world oil crisis seventies in 20th century, and making coal is a kind of fluid fuel from traditional solid fuel conversion, thereby brings lot of advantages.Coal water slurry is as oil, can pumping, atomizing, storage is with the stable ignition burning and gasify.
The reasonable processing of water-containing sludge and recycling are the key subjects of sewage disposal and environment protection.In present various water-containing sludge treatment processs, heat treating method has prospect most.Mud thermal treatment can not only be rapidly and is made mud reach minimizing largely, and can also make the calorific value in the mud obtain certain utilization.But, containing large quantity of moisture in the mud, generally can reach about 80%, existing heat treating method generally needs sludge-drying in advance, removes large quantity of moisture wherein.The dry in advance of mud needs to consume a large amount of heats, and can produce the poisonous and hazardous stench tail gas of a large amount of refractory reasons, causes existing mud heat treatment technics cost height, and power consumption is high, problems such as tail gas refractory reason.
Coal being mixed with water-containing sludge, and adopt certain technique means, with mixture preparation becoming sludge coal slurry, as fuel, is the previous very noticeable problem of order.
Pulping concentration is the most important technical indicator that influences sludge coal slurry burning and gasification efficiency.Water in the sludge coal slurry not only can not provide heat, and also can evaporate and cause thermosteresis in burning and gasification.Existing patented technology, the medicament that in the process of preparation sludge coal slurry, adds the energy modified sewage sludge as Chinese patent 200410024452.X, cause the pulping concentration of sludge coal slurry not high, generally be lower than 55wt%, cause too much thermosteresis in actual applications easily.
Stability also is to estimate one of good important parameter of sludge coal slurry, and existing patented technology need add certain amount of stabilizer as the sludge coal slurry of preparing in the Chinese patent 200410021357.4 and keep its stability.
The discharging of tail gas is the problem that very easily produces in the sludge coal slurry preparation process.Mud contains the organism of large amount of complex, very easily produces toxic and harmful after the thermal treatment.Existing patented technology, as United States Patent (USP) 99814537.8, its defective is to prepare the preceding sex change operation of sludge coal slurry and has produced toxic and harmful, has increased the technology cost of sludge coal slurry preparation.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of high concentration sludge coal slurry and preparation method thereof, to overcome the shortcoming and defect of above-mentioned prior art.
The component of high concentration sludge coal slurry of the present invention and parts by weight content comprise:
100～200 parts of coal dusts
10～50 parts of water-containing sludges
10～100 parts in water
1～5 part of additive
1～5 part of sludge modification medicament
Wherein, the particle diameter of solid particulate is no more than 0.5mm.
In the said water-containing sludge, water ratio is 50～95%, weight;
Described coal is selected from brown coal, bituminous coal, hard coal or its mixture;
Described water-containing sludge is selected from the sewage sludge of municipal sewage plant's generation, wastewater sludge, the paper mill effluent that Industrial Wastewater Treatment produces handled paper mill sludge or its mixture that produces;
Additive is any one or a few in naphthalenesulfonate, polycarboxylate or the sulfonated lignin;
The sludge modification medicament is any one or a few in lime carbonate, yellow soda ash, sodium bicarbonate, salt of wormwood, calcium hydroxide, sodium hydroxide or the potassium hydroxide.
The preparation method of said high concentration sludge coal slurry comprises the steps:
Water-containing sludge is mixed with the sludge modification medicament, obtain the modification water-containing sludge, preferably mix the back and placed 2～240 hours;
Then above-mentioned modification water-containing sludge, coal dust, water and additive are mixed, grind, the particle diameter that makes solid particulate promptly obtains said high concentration sludge coal slurry less than 0.5mm.
The present invention is simple to operate, and power consumption is few, and cost is low, and the secondary pollution of generation is few.This preparation method has the advantage and the effect of the sludge forming performance that improves sludge coal slurry, and pulping concentration can be brought up to more than 55%, and apparent viscosity is below 1000mPas simultaneously, need not additionally to add stablizer, long-time placement can not produce hard-caked sediment, and mobile fine, is fit to pumping.
The high concentration sludge coal slurry of the present invention's preparation can be used as fuel combustion or gasification, calorific value in the mud is fully used, but also it is high to have overcome existing water-containing sludge thermal treatment power consumption, problems such as tail gas and residue poisonous and harmful refractory reason, and do not discharge a large amount of poisonous and hazardous tail gas in the preparation process.
