Description
技术领域technical field
本实用新型涉及一种脱硫系统，具体涉及一种基于相变活性焦干法的脱硫系统。The utility model relates to a desulfurization system, in particular to a desulfurization system based on a phase change active coke dry method.
背景技术Background technique
在燃煤电站烟气脱硫领域，目前90％以上采用的都是石灰石—石膏湿法烟气脱硫工艺，该工艺虽然技术成熟，应用广泛，但在应用过程中其缺点也逐渐显现出来：1)水耗高：对于不设烟气换热器GGH的电站锅炉烟气脱硫装置，折合每百万千瓦机组的耗水量高达150～200m3/h；2)烟囱防腐和“石膏雨”问题：湿法脱硫装置的出口烟气为饱和湿烟气，必须对烟囱进行高等级防腐，还可能出现烟囱“石膏雨”问题，对周边环境造成二次污染；3)净烟气液滴携带问题：净烟气中携带的液滴为20％左右浓度的石膏浆液，其中含有一定的固体颗粒，排入大气中即为粉尘污染；4)石灰石大量开采和石膏堆积问题：由于广泛采用石灰石—石膏湿法烟气脱硫工艺，导致大量石灰石山被开采，还造成部分地区的脱硫石膏堆积。In the field of flue gas desulfurization of coal-fired power plants, more than 90% of them currently use limestone-gypsum wet flue gas desulfurization technology. Although this technology is mature and widely used, its shortcomings are gradually emerging during the application process: 1) High water consumption: For power plant boiler flue gas desulfurization devices without flue gas heat exchanger GGH, the water consumption per million kilowatt units is as high as 150-200m 3 /h; 2) Chimney anticorrosion and "gypsum rain" problems: wet The flue gas at the outlet of the desulfurization device using the desulfurization method is saturated wet flue gas, and high-level anti-corrosion must be carried out on the chimney, and the problem of "gypsum rain" in the chimney may also occur, causing secondary pollution to the surrounding environment; The liquid droplets carried in the flue gas are gypsum slurry with a concentration of about 20%, which contains certain solid particles, which is dust pollution when discharged into the atmosphere; 4) The problem of massive limestone mining and gypsum accumulation: due to the widespread use of limestone-gypsum The flue gas desulfurization process has led to the mining of a large number of limestone mountains, and also caused the accumulation of desulfurized gypsum in some areas.
根据我国煤电发展规划，未来将重点建设大型煤电基地，我国富煤地区主要位于北方，也正是缺水地区。活性焦干法烟气净化工艺耗水量小，较传统湿法脱硫节水90％以上，而且吸附剂活性焦由煤炭制取，副产物为浓硫酸可资源化利用，不会造成大量石灰石开采和石膏堆积问题。另外，在环境保护重点地区，环境容量小，环保标准严格，活性焦烟气净化工艺可以对SO2、SO3、NOx、HCl、HF、Hg、细微粉尘等进行同时高效脱除，而且没有传统湿法脱硫的“石膏雨”、净烟气液滴携带等问题，可以满足十分严格的环保标准，适用于环境敏感地区的烟气净化。According to my country's coal power development plan, the future will focus on building large-scale coal power bases. my country's coal-rich areas are mainly located in the north, which is also a water-scarce area. The activated coke dry flue gas purification process consumes less water, saving more than 90% of water compared with the traditional wet desulfurization, and the adsorbent activated coke is made of coal, and the by-product is concentrated sulfuric acid, which can be recycled and utilized, and will not cause a large amount of limestone mining and Gypsum buildup problem. In addition, in the key areas of environmental protection, the environmental capacity is small and the environmental protection standards are strict. The activated coke flue gas purification process can simultaneously and efficiently remove SO 2 , SO 3 , NOx, HCl, HF, Hg, fine dust, etc., and there is no traditional The "gypsum rain" of wet desulfurization and the carryover of clean flue gas droplets can meet very strict environmental protection standards and are suitable for flue gas purification in environmentally sensitive areas.
此外，对于钢铁烧结烟气、垃圾焚烧烟气的净化处理，活性焦可以同时吸附其中的二噁英污染物，而传统的湿法脱硫工艺无法对二噁英进行有效脱除。因此，活性焦适用于对烧结烟气和垃圾焚烧烟气中的多污染物脱除和深度净化。In addition, for the purification of steel sintering flue gas and waste incineration flue gas, activated coke can simultaneously adsorb dioxin pollutants, while the traditional wet desulfurization process cannot effectively remove dioxin. Therefore, activated coke is suitable for multi-pollutant removal and deep purification of sintering flue gas and waste incineration flue gas.
活性焦吸附塔内要控制活性焦与烟气接触反应时间，吸附塔一般体积较大或者活性焦吸附塔脱硫单元数量增多，造成了活性焦干法脱硫系统占地面积大、初期建设投资高，另外，活性焦吸附脱硫效率受烟气温度影响较大，为了要达到较高的脱硫效率导致初期建设投资升高，这些因素对活性焦干法脱硫推广应用不利，因此亟需开发能够降低活性焦脱硫系统投资成本的新系统。The contact reaction time between activated coke and flue gas should be controlled in the activated coke adsorption tower. Generally, the volume of the adsorption tower is large or the number of desulfurization units in the activated coke adsorption tower increases, resulting in a large area of active coke dry desulfurization system and high initial construction investment. In addition, the adsorption and desulfurization efficiency of activated coke is greatly affected by the flue gas temperature. In order to achieve a higher desulfurization efficiency, the initial construction investment will increase. These factors are not conducive to the popularization and application of activated coke dry desulfurization. New system of desulfurization system investment cost.

原烟气从烟气相变换热器2的烟气入口进入烟气相变换热器2内，并与烟气相变换热器2中的管束进行换热，使原烟气的温度降低，并使原烟气中的水蒸气凝结，再经原烟气分配管道6调节后进入活性焦脱硫吸附塔的原烟气集气室8中，并在原烟气集气室8中均匀分散后穿过烟气脱硫段12进入到中间集气腔室10内，然后再穿过烟气脱硫段12进入到净烟气集气室11内，实现烟气的脱硫，净烟气集气室11内的净烟气经烟囱17排出，其中，烟气经烟气脱硫段12中的活性焦进行脱硫处理，脱硫后的活性焦经烟气脱硫段12底部的活性焦出口排出，再经活性焦A输送链条19进入到活性焦解析塔中；The raw flue gas enters the flue gas phase change heat exchanger 2 from the flue gas inlet of the flue gas phase change heat exchanger 2, and exchanges heat with the tube bundle in the flue gas phase change heat exchanger 2, so that the temperature of the raw flue gas reduce, and condense the water vapor in the original flue gas, and then enter the original flue gas collection chamber 8 of the activated coke desulfurization adsorption tower after being regulated by the original flue gas distribution pipe 6, and evenly disperse in the original flue gas collection chamber 8 After that, it passes through the flue gas desulfurization section 12 and enters the intermediate gas collection chamber 10, and then passes through the flue gas desulfurization section 12 and enters the clean flue gas collection chamber 11 to realize the desulfurization of the flue gas and clean the flue gas collection chamber. The net flue gas in 11 is discharged through the chimney 17, wherein the flue gas is desulfurized by the activated coke in the flue gas desulfurization section 12, and the desulfurized active coke is discharged through the active coke outlet at the bottom of the flue gas desulfurization section 12, and then passed through the activated coke The coke A conveying chain 19 enters the active coke analysis tower;
在活性焦解析塔中，脱硫后的活性焦依次经过给料段21、预热段22、第一缓冲段23、解析段24、第二缓冲段25及冷却段26解析再生，再生的活性焦经出料段27进入到振动筛15中，然后再经活性焦B输送链条20进入到活性焦脱硫吸附塔的进料口14内，再经布料器13分配后在重力的作用下进入到烟气脱硫段12中。In the activated coke analysis tower, the activated coke after desulfurization is analyzed and regenerated through the feeding section 21, the preheating section 22, the first buffer section 23, the analysis section 24, the second buffer section 25 and the cooling section 26, and the regenerated active coke Enter the vibrating screen 15 through the discharge section 27, and then enter the feed port 14 of the active coke desulfurization adsorption tower through the active coke B conveying chain 20, and then enter the smoke under the action of gravity after being distributed by the distributor 13. In the gas desulfurization section 12.
