雜質(zhì)去除?

Impurity removal

合金尾氣含粉塵等雜質(zhì)，會磨損發(fā)動機部件。需在進氣管道前端設(shè)旋風(fēng)、布袋等高效除塵設(shè)備。如某銅合金廠起初未除塵，發(fā)動機運行三月后嚴重磨損，加裝布袋除塵器后，除塵效率超 99%，問題解決。?

Alloy exhaust contains impurities such as dust, which can wear down engine components. Efficient dust removal equipment such as cyclones and bags should be installed at the front end of the intake duct. If a copper alloy factory initially did not remove dust, the engine would suffer severe wear after running for three months. After installing a bag filter, the dust removal efficiency exceeded 99%, and the problem was solved. ?

成分調(diào)節(jié)?

Ingredient regulation

尾氣中一氧化碳、氫氣等可燃成分濃度要合適，否則燃燒不穩(wěn)定甚至有爆炸風(fēng)險?？裳b在線氣體分析儀，配自動調(diào)節(jié)裝置，依濃度調(diào)節(jié)尾氣與空氣混合比例。如鋅合金冶煉尾氣發(fā)電項目，用 PLC 系統(tǒng)依分析儀數(shù)據(jù)，自動調(diào)進氣閥門開度，穩(wěn)定可燃成分濃度。?

The concentration of combustible components such as carbon monoxide and hydrogen in exhaust gas should be appropriate, otherwise the combustion will be unstable and there may even be a risk of explosion. Can be equipped with an online gas analyzer, equipped with an automatic adjustment device, to adjust the mixing ratio of exhaust gas and air according to concentration. For the zinc alloy smelting tail gas power generation project, a PLC system is used to automatically adjust the opening of the intake valve based on analyzer data, stabilizing the concentration of combustible components. ?

溫度控制?

Temperature control

尾氣溫度常過高，會降低潤滑油黏度、引發(fā)爆震。要設(shè)水冷式換熱器等冷卻裝置，降低尾氣溫度。某鋁合金廠尾氣從 400℃冷卻至 150℃，滿足了發(fā)電機組進氣要求。

The exhaust temperature is often too high, which can reduce the viscosity of lubricating oil and cause detonation. Cooling devices such as water-cooled heat exchangers should be installed to reduce the exhaust gas temperature. The exhaust gas from a certain aluminum alloy factory was cooled from 400 ℃ to 150 ℃, meeting the intake requirements of the generator set.

發(fā)電參數(shù)監(jiān)測?

Power generation parameter monitoring

密切留意輸出電壓、電流、頻率。電壓不穩(wěn)易損用電設(shè)備，頻率偏差影響電力質(zhì)量與電網(wǎng)接入。通過智能電表和電力監(jiān)測系統(tǒng)采集數(shù)據(jù)，參數(shù)異常時自動報警并調(diào)節(jié)。如某鎳合金發(fā)電站用遠程監(jiān)控系統(tǒng)，電壓波動 ±5% 時，系統(tǒng)自動調(diào)勵磁電流穩(wěn)定電壓。?

Pay close attention to the output voltage, current, and frequency. Unstable voltage can easily damage electrical equipment, and frequency deviation affects power quality and grid connection. Data is collected through smart meters and power monitoring systems, and automatic alarms and adjustments are made when parameters are abnormal. If a nickel alloy power station uses a remote monitoring system, when the voltage fluctuates by ± 5%, the system automatically adjusts the excitation current to stabilize the voltage. ?

發(fā)動機狀態(tài)監(jiān)測?

Engine condition monitoring

發(fā)動機是核心，要監(jiān)測機油壓力、冷卻液溫度、轉(zhuǎn)速等。機油壓力低影響潤滑，冷卻液溫度高易致發(fā)動機過熱。通過壓力、溫度等傳感器傳輸數(shù)據(jù)，實現(xiàn)故障預(yù)警。某鈷合金廠在發(fā)動機裝多個傳感器，提前發(fā)現(xiàn)并解決多次潛在故障。

The engine is the core and needs to monitor oil pressure, coolant temperature, speed, etc. Low oil pressure affects lubrication, and high coolant temperature can easily cause engine overheating. By transmitting data through sensors such as pressure and temperature, fault warning can be achieved. A certain cobalt alloy factory installed multiple sensors in the engine to detect and solve potential faults in advance.

尾氣排放監(jiān)測?

Exhaust emission monitoring

發(fā)電時仍要監(jiān)測尾氣排放，安裝設(shè)備監(jiān)測二氧化硫、氮氧化物、顆粒物等濃度，確保達標(biāo)。超標(biāo)時排查燃燒、尾氣處理裝置等問題并整改。如某鉛合金廠因活性炭吸附飽和未換，致二氧化硫超標(biāo)停產(chǎn)，更換并加強監(jiān)測后復(fù)產(chǎn)。?

During power generation, it is still necessary to monitor exhaust emissions and install equipment to monitor concentrations of sulfur dioxide, nitrogen oxides, particulate matter, etc., to ensure compliance with standards. When exceeding the standard, investigate and rectify issues with combustion and exhaust treatment devices. If a lead alloy factory fails to replace activated carbon due to saturation adsorption, resulting in excessive production of sulfur dioxide, it will resume production after replacement and strengthened monitoring. ?

防火防爆措施?

Fire and explosion prevention measures

合金尾氣易燃易爆，運行區(qū)要設(shè)防火隔離帶，嚴禁煙火。安裝可燃氣體泄漏報警裝置，搭配通風(fēng)系統(tǒng)。電氣設(shè)備采用防爆型，避免電火花引發(fā)爆炸。某鎂合金廠車間裝多個探測器，全方位監(jiān)測泄漏，保障安全。

Alloy exhaust gas is flammable and explosive. Fire isolation zones should be set up in the operating area, and smoking and open flames are strictly prohibited. Install a combustible gas leak alarm device and equip it with a ventilation system. The electrical equipment adopts explosion-proof type to avoid explosions caused by electric sparks. Multiple detectors are installed in the workshop of a magnesium alloy factory to comprehensively monitor leaks and ensure safety.
