1負(fù)壓上料系統(tǒng)
1 negative pressure feeding system
負(fù)壓上料裝置輸送的方式是由操作人員通過負(fù)壓管從料包中將脫硝藥劑吸入料倉內(nèi)，很大程度地節(jié)省了人員的操作時間及勞動強(qiáng)度，節(jié)約了人工成本。
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輸送系統(tǒng)
2 conveying system
羅茨風(fēng)機(jī)是整個輸送系統(tǒng)主要的組件之一，它為整個系統(tǒng)提供足夠的風(fēng)量及風(fēng)壓，根據(jù)運行情況變頻調(diào)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下料器系統(tǒng)
3. Feeder system
卸料器由驅(qū)動電機(jī)采用變頻控制，以適應(yīng)鍋爐工況的調(diào)節(jié)，具有運行穩(wěn)定、抗壓性能好、耐磨損的特點，同時與垃圾焚燒爐在線數(shù)據(jù)連接，做到實時跟蹤調(diào)整，節(jié)約脫硝劑成本。
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干法脫硝噴射系統(tǒng)
4 dry denitration injection system
干法脫硝噴射系統(tǒng)主要由噴槍及其附件組成，通過調(diào)節(jié)下料器的變頻器頻率控制脫硝劑輸送量。輸送管與球形分配器連接，球形分配器出口管通過金屬軟管連接噴槍。噴槍采用耐磨損、耐熱變形、耐高溫、耐腐蝕且容易維護(hù)的材料；霧化效果及覆蓋面積經(jīng)過流場模擬和數(shù)值計算。
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控制系統(tǒng)
5 control system
采用的為PLC自動化控制，根據(jù)鍋爐煙氣在線實時數(shù)據(jù)反饋對加料量進(jìn)行PID自動控制，實現(xiàn)干法脫硝系統(tǒng)的自動化控制。
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.
