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.
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.
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.

羅茨風機是整個輸送系統主要的組件之一，它為整個系統提供足夠的風量及風壓，根據運行情況變頻調整。
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.
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.
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.
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.
