Description
技术领域 technical field
本实用新型涉及焦炉燃烧废气净化领域,特别涉及一种焦炉燃烧废气脱硝系统。 The utility model relates to the field of coke oven combustion waste gas purification, in particular to a coke oven combustion waste gas denitrification system.
背景技术 Background technique
焦化企业在生产过程中会产生大量的焦炉燃烧废气,这里所说的焦炉燃烧废气是指由煤气与空气在焦炉立火道内混合燃烧所产生的气体。所产生的焦炉燃烧废气中含有大量的氮氧化物(NOx)。现在各焦化企业的焦炉燃烧废气均需经过立火道、蓄热室、小烟道、废气交换开闭器、分烟道、总烟道、烟囱排入大气,其中蓄热室位于焦炉本体中部是回收废气余热的单元,焦炉燃烧废气的直接排放给环境造成严重污染。我国规定自2015年1月1日起,现有焦化企业必须执行GB16171-2012排放标准。也就是说,焦化企业以后产生的焦炉燃烧废气在排放之前必须经过脱硝(即脱氮氧化物)处理。 Coking enterprises will produce a large amount of coke oven combustion exhaust gas during the production process. The coke oven combustion exhaust gas mentioned here refers to the gas produced by the mixed combustion of coal gas and air in the coke oven vertical flue. The coke oven combustion exhaust gas produced contains a large amount of nitrogen oxides (NO x ). At present, the coke oven combustion waste gas of various coking enterprises needs to be discharged into the atmosphere through the vertical flue, regenerator, small flue, exhaust gas exchange switch, branch flue, main flue, and chimney, and the regenerator is located in the coke oven. The middle part of the main body is the unit for recovering the waste heat of the waste gas, and the direct discharge of the waste gas from the combustion of the coke oven causes serious pollution to the environment. my country stipulates that from January 1, 2015, existing coking enterprises must implement the GB16171-2012 emission standard. That is to say, the coke oven combustion exhaust gas produced by coking enterprises must be denitrified (that is, denitrified oxides) before being discharged.
选择性催化还原技术(SelecitveCatalyticReduction,简称SCR)是比较成熟的脱硝技术,该技术由于具有不形成二次污染、装置结构简单、并且脱硝效率高(可达90%以上),运行可靠、便于维护等特点,已广泛应用于电力、水泥、玻璃等行业。采用SCR技术进行脱硝时,待脱硝气体的温度要达到250℃以上。但是,焦化企业产生的焦炉燃烧废气在经过蓄热室回收热量后,其温度会下降到250℃以下,无法满足采用SCR技术进行脱硝的要求。 Selective catalytic reduction technology (SelecitveCatalyticReduction, referred to as SCR) is a relatively mature denitrification technology. This technology has no secondary pollution, simple device structure, high denitrification efficiency (up to 90%), reliable operation, and easy maintenance. Features, has been widely used in electric power, cement, glass and other industries. When SCR technology is used for denitrification, the temperature of the gas to be denitrated must reach above 250°C. However, the temperature of coke oven combustion waste gas produced by coking enterprises will drop below 250°C after heat recovery in the regenerator, which cannot meet the requirements of SCR technology for denitrification.
因此,开发出一种能够采用SCR技术实现焦炉燃烧废气脱硝的系统十分必要。 Therefore, it is necessary to develop a system that can use SCR technology to realize denitrification of coke oven combustion exhaust gas.

所述SCR脱硝装置3具有废气入口和废气出口,其废气入口通过烟气管路2与焦炉1的蓄热室废气出口相连; The SCR denitrification device 3 has a waste gas inlet and a waste gas outlet, and the waste gas inlet is connected to the regenerator waste gas outlet of the coke oven 1 through the flue gas pipeline 2;
所述SCR脱硝装置3的废气出口通过烟气管路2与所述引风机4的废气入口相连;所说的引风机4优选配有变频电机,通过对引风机4进行变频调速,既能保证焦炉1正常生产所需要的负压,也能保证焦炉燃烧废气通过SCR脱硝装置3所需要的压力值; The exhaust gas outlet of the SCR denitrification device 3 is connected to the exhaust gas inlet of the induced draft fan 4 through the flue gas pipeline 2; It can ensure the negative pressure required for the normal production of the coke oven 1, and can also ensure the pressure value required for the coke oven combustion exhaust gas to pass through the SCR denitrification device 3;
