适用于燃气轮机后烟气脱硝无稀释水的SCR脱硝系统
摘要：
本实用新型公开了一种适用于燃气轮机后烟气脱硝无稀释水的SCR脱硝系统，其包括尿素溶解罐、尿素溶液存储罐、尿素溶液供应泵、流量调节装置、喷枪、压缩空气供应系统、燃气排烟机的排烟管道和余热锅炉；所述尿素溶解罐通过尿素溶液泵与尿素溶液存储罐连接，所述尿素溶液存储罐通过尿素溶液供应泵和流量调节装置与喷枪连接；所述喷枪还与压缩空气供应系统连接；所述喷枪安装在排烟管道内，所述排烟管道还与余热锅炉连接；所述喷枪安装在排烟管道的350℃-650℃的温度段中。本实用新型将尿素颗粒加除盐水溶解，溶液后的尿素溶液浓度为5%，所以制备尿素溶液浓度较低，尿素溶液输送泵至喷枪之间不需要加装稀释水系统。
摘要（英）：

The utility model discloses an SCR (Selective Catalytic Reduction) denitration system suitable for denitration of rear smoke of a gas turbine without dilution water. The SCR denitration system comprises a urea dissolving tank, a urea solution storage tank, a urea solution supply pump, a flow regulating device, a spray gun, a compressed air supply system, a smoke exhaust pipeline of a gas smoke exhauster and a waste heat boiler, wherein the urea dissolving tank is connected with the urea solution storage tank through the urea solution pump, and the urea solution storage tank is connected with the spray gun through the urea solution supply pump and the flow regulating device; the spray gun is also connected with a compressed air supply system; the spray gun is installed in a smoke exhaust pipeline, and the smoke exhaust pipeline is further connected with a waste heat boiler. And the spray gun is arranged in the temperature section of the smoke exhaust pipeline at 350-650 DEG C. Accordingto the utility model, urea particles are dissolved in desalted water, and the concentration of the urea solution after solution is 5%, so that the concentration of the prepared urea solution is lower, and a dilution water system does not need to be additionally arranged between the urea solution delivery pump and the spray gun.
