本发明涉及一种用于粉煤气化的多级粉煤携带床固态排渣气化炉。The invention relates to a multi-stage pulverized coal carried bed solid-state slagging gasification furnace for pulverized coal gasification.
背景技术Background technique
煤的洁净与高效利用是当今世界能源与环境保护领域的重大技术课题，也是我国国民经济和社会可持续发展的关键技术之一。煤气化技术作为煤炭深度加工、转化的先导技术，是洁净煤技术的关键。煤气化是指将煤投放在气化炉内，在一定的温度及压力条件下，煤中有机质与气化剂(如蒸汽/空气或氧气等)发生一系列化学反应，将固体煤转化为含有CO、H2、CH4等可燃气体和CO2、N2等非可燃气体的过程。煤的气化技术在联合循环(IGCC)发电装置、合成氨以及合成甲醇等行业应用极为广泛，而气化炉则是煤气化的关键设备。因此，世界各国的科技人员研究和开发出了各种类型的气化炉。其中，气流床与固定床、流化床相比，气流床具有较好的煤种与粒度适应性和更优良的技术性能，是煤基大容量、高效洁净、运行可靠的燃气与合成气制备装置的首选技术。The clean and efficient utilization of coal is a major technical issue in the field of energy and environmental protection in the world today, and it is also one of the key technologies for the sustainable development of my country's national economy and society. Coal gasification technology, as a leading technology for coal deep processing and transformation, is the key to clean coal technology. Coal gasification refers to putting coal in the gasifier, and under certain temperature and pressure conditions, a series of chemical reactions occur between the organic matter in the coal and the gasification agent (such as steam/air or oxygen, etc.), and the solid coal is converted into The process of flammable gases such as CO, H 2 , CH 4 and non-combustible gases such as CO 2 , N 2 . Coal gasification technology is widely used in combined cycle (IGCC) power generation units, synthetic ammonia and synthetic methanol industries, and the gasifier is the key equipment for coal gasification. Therefore, scientists and technicians from all over the world have researched and developed various types of gasifiers. Among them, compared with fixed bed and fluidized bed, entrained air bed has better coal type and particle size adaptability and better technical performance. The preferred technology for the device.
目前，采用气流床进行气化的技术中，有代表性的主要技术流派有：采用水煤浆为原料，液态排渣的美国Texaco气化炉和以干煤粉为原料，液态排渣的荷兰Shell气化炉。At present, in the gasification technology using entrained bed, the main representative technical schools are: the American Texaco gasifier which uses coal water slurry as raw material and liquid slag discharge, and the Dutch gasifier which uses dry coal powder as raw material and liquid slag discharge. Shell gasifier.
美国Texaco气化炉，水煤浆由气化炉炉顶向下喷入，在炉内进行熔渣气化。由于物料在该气化炉内的停留时间分布较宽，部分物料在炉内的停留时间很短，没有达到平均停留时间就逸出炉外，因此，碳转化率一般低于95％。美国Texaco气化炉的气化操作温度为1400～1500℃，气化操作压力为2.5～8.5Mpa。美国Texaco气化炉世界范围内的商业化市场占有量大，技术成熟，它因煤浆制备、计量、输送、控制简单，安全可靠，操作压力高，可达6.5MPa和投资低等技术特点得到广泛应用。In the Texaco gasifier in the United States, the coal water slurry is sprayed downward from the top of the gasifier, and the slag is gasified in the furnace. Due to the wide distribution of the residence time of the materials in the gasifier, the residence time of some materials in the furnace is very short, and they escape out of the furnace before reaching the average residence time. Therefore, the carbon conversion rate is generally lower than 95%. The gasification operating temperature of the American Texaco gasifier is 1400-1500°C, and the gasification operating pressure is 2.5-8.5Mpa. The American Texaco gasifier has a large commercial market share in the world, and its technology is mature. It is easy to prepare, measure, transport and control coal slurry, safe and reliable, high operating pressure, up to 6.5MPa and low investment. widely used.
荷兰Shell气化炉属加压对喷式粉煤液态排渣气化炉。干煤粉用加压锁式煤斗，靠氮气或CO2气流输送，与氧气及少量水蒸汽混合喷入炉内，气化炉温度维持在1400～1600℃，形成的熔渣在中间底部排渣口排出，煤气出炉后采用回流冷煤气激冷方式。该炉装有四个煤粉燃烧器，并装设水冷壁，在水冷壁中将产生饱和蒸汽。The Holland Shell gasifier is a pressurized counter-spray pulverized coal liquid slagging gasifier. The dry coal powder is transported in a pressurized lock-type coal hopper by nitrogen or CO 2 gas flow, mixed with oxygen and a small amount of water vapor and sprayed into the furnace. The slag outlet is discharged, and the gas is quenched by reflux cold gas after it is released from the furnace. The furnace is equipped with four pulverized coal burners and is equipped with a water wall in which saturated steam will be generated.
荷兰Shell气化炉与美国Texaco气化炉相比，冷煤气效率高6～8个百分点，比煤耗和比氧耗大幅度下降，煤种适应性更广，气化系统的投资基本相当。Compared with the US Texaco gasifier, the Holland Shell gasifier has a 6-8% higher cold gas efficiency, significantly lower specific coal consumption and specific oxygen consumption, wider adaptability of coal types, and basically the same investment in the gasification system.
在我国，煤的商业化和社会化迄今已有100余年，但没有形成能与国际抗衡的商业化自主产权煤气化技术。20世纪70年代起西北化工研究院研究开发了水煤浆气化技术并建设了中试装置，为此后4家厂引进Texaco水煤浆气化技术提供了丰富的经验。In my country, coal has been commercialized and socialized for more than 100 years, but there is no commercial independent property right coal gasification technology that can compete with the world. Since the 1970s, the Northwest Research Institute of Chemical Industry has researched and developed the coal-water slurry gasification technology and built a pilot plant, which provided rich experience for the introduction of Texaco coal-water slurry gasification technology to four factories thereafter.
