Abstract
The invention discloses a preparation method of novel water coal slurry capable of realizing high efficiency desulphurization during combustion. According to the preparation method, desulphurization during combustion (namely in-furnace desulphurization) is realized by adding a desulfurizing agent, such as in-furnace limestone injection, briquette sulfur and a desulfurization additive, and pulverized coal is combusted, so that sulfur in the coal is converted into sulfate and discharged along with slags, and by adopting the method, 50%-60% of sulfur in the coal can be removed. The typical technology is a circulating fluidized bed technology, such as a CFBC (Circulating Fluidized Bed Combustion) boiler, an LIMB (Limestone Injection Multistage Burner), and LIFAC (Limestone Injection into the Furnace and Activation of Calcium). According to the invention, separated waste liquid after straw alkali treatment, and various compounds in the waste liquid not only can serve as an excellent desulfurizing agent for coal, but also has a certain heat value, so that combustion of the coal is facilitated. On one hand, alkali lignin and lignin sulfonate in the waste liquid can react with sulfur ions to form a stable structure, so that sulfur generated by coal combustion is removed, and on the other hand, residual alkali and oxides in the waste liquid are separated and are subjected to oxidation reaction with sulfur in the coal to generate stable sulfate ions, so that a sulfur fixation effect is realized. Desulfurization and sulfur fixation are both realized, and the desulfurization effect is obvious.
Description
Technical field
The present invention starts with from making full use of stalk resource, adopts alkaline purification stalk, reacts and generates rock steady structure, remove the sulphur produced in coal burning in its waste liquid containing alkali lignin and Sulfite lignin and sulfonium ion; Be separated reaction of Salmon-Saxl in residual alkali in waste liquid and oxide compound and coal and be oxidized to stable sulfate ion, play the effect of solid sulphur; And there is certain calorific value, can with fire coal co-fire in stove.After adding CaO, the sulphur that can remove with black liquor in combustion processes reacts, and generates CaSO
4, finally discharge with slag.Thus the environmental pollution that solution crop straw burning brings, additionally reduce sulfurous gas, oxynitride etc. that coal burning discharges, and waste liquid obtains comprehensive utilization.
Background technology
In the past few decades, agricultural crop straw major part is fallen by as castoff burning, and a large amount of stalks causes serious atmospheric pollution in burning process.For reducing environmental pollution, people take multiple technologies means and fully utilize it.The technology that utilizes of agricultural crop straw mainly can be summarized as following 4 kinds: straw-returning technology, energy technology, fodder technology and industrial utilization technology.Along with the quickening of process of industrialization, energy cost is also improving constantly, and stalk is extensively present in human production activity as one, and is easy to the biomass resource of acquisition, therefore, its high value added utilization technology mainly concentrates on energy and industrial utilization two aspects.Major way has:
(1) fiber extracts: Zhong Yemeili limited-liability company is by carrying out gluten substitute to maize straw, determine digesting technoloy empirical curve, extract the Mierocrystalline cellulose of high-quality, meeting generating portion waste liquid in Mierocrystalline cellulose leaching process, but containing a large amount of alkali lignins and Sulfite lignin in waste liquid, recycle more difficult.
(2) straw ethanol: relative to the first-generation biofuel being raw material with the grain such as corn and soybean, the cellulosic ethanol being raw material with vegetable fibres such as stalks is called as s-generation biofuel, utilize biotechnology that lignocellulose is changed into ethanol, there is important society and economic implications.Utilize stalk more and more to come into one's own to produce alcohol fuel, but due to the complicated component of stalk, usually will carry out various pre-treatment to stalk, preprocessing process technology is immature, and waste liquid cannot process, and fermentation cellulase price is high, make production cost high, be difficult to promote;
(3) stalk makes the energy: although agricultural crop straw just starts a long time ago as fuel, and normally even incinerate in farmland for burning of cooking a meal, heating, be in poor efficiency utilization state, turnover ratio is only 10% ~ 20%.Until during the first oil crisis in 1973, Denmark just takes the lead in research and utilization stalk as fuel used to generate electricity, and first hand straw burning power station Haslev put into operation in 1988.After this, built large number of biological power station in West Europe, wherein maximum power station is the Elyan power station of Britain, and installed capacity is 38MW.As can be seen here, namely straw boiler is be utilized as object with efficient burning at the beginning of research, to stop the environmental pollution that conventional burning mode is brought.China is as large agricultural country, and people in the countryside are numerous, and biomass resource is very abundant, and as far back as 2010, agricultural straw resource was more than 7.2 hundred million t/a, and wherein 6.04 hundred million t/a can be used as energy use.By introducing, digesting foreign technology, domestic conventional stalk direct combustion stove is divided into: combined grate boiler, water-cooling vibration furnace grate boiler and circular fluid bed.Domesticly building with in Built Projects, the water-cooling vibration furnace grate formula boiler that the Denmark BWE of employing technology manufactures more and water-cooling vibration furnace grate stove in the majority.Circular fluid bed, under the promotion of institute, designing institute, manufacturer, starts to enter biomass fermentation electrical domain.
Desulfurization and rear pass desulfurization technology of burning in desulfurization before desulfurization technology comprises burning, combustion processes.Reduce SO
2the most economical method of pollutent is the high-sulfur low grade coal stopping burning S>=3%, uses low-sulfur fat coal instead, can not only reduce SO in air in a large number
2pollute, obtain social influence, and improve the thermal value of coal simultaneously, reduce fortune coal amount and lime-ash treatment capacity and obtain economic benefit.
Simultaneously desulfurization in burning (i.e. desulfuration in furnace) drops into a certain amount of sweetening agent in the process of coal dust firing, makes the sulphur in coal change into vitriol, and discharge with slag, this method can remove the sulphur of in coal 50% ~ 60%.As in-furnace calcium spraying, capturing sulfur briquette with utilize sweetening additive etc., typical technology is circulating fluidized bed technique.Such as adopt circular fluid bed (CFBC), spray into the multistage burner (LIMB) of limestone desulfurizer and in-furnace calcium spraying and afterbody humidification activation (LIFAC) etc.Along with CFBC boiler capacity increases, not only replace part arcola, and replace pulverized coal furnace of hydropower station gradually.
Domestic and international improvement, utilize the main method of papermaking wastewater: alkali collection, coal water slurry (compound) additive, acid-precipitation method, biochemical process, electroosmose process, flocculation sediment oxidation style, membrane technology, COAL-WATER SLURRY TECHNOLOGY and Integrated Membrane Technology etc.China's paper industry generally adopts alkaline process, the solids of 70% is about had to be organism in black digestion liquid, xylogen is wherein a kind of biomass being rich in calorific value, general pulp black liquor adopts alkali collection reclaim heat generating or produce steam reuse mostly, but invest huge, and stalk slurrying alkali collection exists problems such as alkali recovery efficiency is low, of poor benefits, silicon obstacle, stalk slurrying is become history.
The present invention is by the combination of desulfurization technology and coal water slurry process in stalk alkaline hydrogen peroxide pulping technique, burning; prepare a kind of novel coal water slurry; first achieve the efficiency utilization of stalk resource, have again efficient sweetening effectiveness, two aspects reach the effect of environment protection jointly.The reaction occurred in sweetening process in novel water-coal-slurry burning:
