高分子干法脱硝工艺在垃圾炉运行

高分子脱硝设备进行了模块化设计,利于现场快速安装,该系统主要包括:上料系统、输送系统、下料器系统、喷射系统、控制系统。

The polymer denitration equipment is modularized to facilitate the rapid installation on site. The system mainly includes: feeding system, conveying system, feeder system, injection system and control system.
在垃圾焚烧炉标高24.7m前墙设置2支喷枪,左右墙标高24.7m各设置1支喷枪,左右墙标高25.9m各设置1支喷枪,单炉共设置6支脱硝喷枪。喷枪采用分层分区域布置,对烟气进行优覆盖,使得氮氧化物达到很好的脱除效率。
Two spray guns are set on the front wall of the waste incinerator with an elevation of 24.7m, one spray gun is set on the left and right walls with an elevation of 24.7m, one spray gun is set on the left and right walls with an elevation of 25.9m, and a total of 6 denitration spray guns are set on a single furnace. The spray gun is arranged in layers and regions to cover the flue gas optimally, so as to achieve good removal efficiency of nitrogen oxides.
1负压上料系统
1 negative pressure feeding system
负压上料装置输送的方式是由操作人员通过负压管从料包中将脱硝药剂吸入料仓内,很大程度地节省了人员的操作时间及劳动强度,节约了人工成本。
The conveying mode of the negative pressure feeding device is that the operator sucks the denitration agent from the material bag into the silo through the negative pressure pipe, which greatly saves the operation time and labor intensity of the personnel and saves the labor cost.
2输送系统
2 conveying system
罗茨风机是整个输送系统主要的组件之一,它为整个系统提供足够的风量及风压,根据运行情况变频调整。
Roots blower is one of the main components of the whole conveying system. It provides sufficient air volume and air pressure for the whole system and can be adjusted by frequency conversion according to the operation.
3下料器系统
3. Feeder system
卸料器由驱动电机采用变频控制,以适应锅炉工况的调节,具有运行稳定、抗压性能好、耐磨损的特点,同时与垃圾焚烧炉在线数据连接,做到实时跟踪调整,节约脱硝剂成本。
The discharger adopts frequency conversion control by the driving motor to adapt to the adjustment of boiler working conditions. It has the characteristics of stable operation, good compressive performance and wear resistance. At the same time, it is connected with the online data of waste incinerator to achieve real-time tracking and adjustment and save the cost of denitration agent.
4干法脱硝喷射系统
4 dry denitration injection system
干法脱硝喷射系统主要由喷枪及其附件组成,通过调节下料器的变频器频率控制脱硝剂输送量。输送管与球形分配器连接,球形分配器出口管通过金属软管连接喷枪。喷枪采用耐磨损、耐热变形、耐高温、耐腐蚀且容易维护的材料;雾化效果及覆盖面积经过流场模拟和数值计算。
The dry denitration injection system is mainly composed of spray gun and its accessories. The conveying amount of denitration agent is controlled by adjusting the frequency converter of the feeder. The conveying pipe is connected with the spherical distributor, and the outlet pipe of the spherical distributor is connected with the spray gun through a metal hose. The spray gun is made of wear-resistant, heat-resistant deformation, high temperature resistant, corrosion-resistant and easy to maintain materials; The atomization effect and coverage area are simulated by flow field and numerical calculation.
5控制系统
5 control system
采用的为PLC自动化控制,根据锅炉烟气在线实时数据反馈对加料量进行PID自动控制,实现干法脱硝系统的自动化控制。
The PLC automatic control is adopted. According to the online real-time data feedback of boiler flue gas, the PID automatic control is carried out for the feeding amount to realize the automatic control of dry denitration system.
