雜質(zhì)去除?

Impurity removal

合金尾氣含粉塵等雜質(zhì)，會(huì)磨損發(fā)動(dòng)機(jī)部件。需在進(jìn)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(dòng)機(jī)運(yùn)行三月后嚴(yán)重磨損，加裝布袋除塵器后，除塵效率超 99%，問(wèn)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(xiǎn)?？裳b在線氣體分析儀，配自動(dòng)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(xiàng)目，用 PLC 系統(tǒng)依分析儀數(shù)據(jù)，自動(dòng)調(diào)進(jìn)氣閥門開(kāi)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(guò)高，會(huì)降低潤(rùn)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(jī)組進(jìn)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(cè)?

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(guò)智能電表和電力監(jiān)測(cè)系統(tǒng)采集數(shù)據(jù)，參數(shù)異常時(shí)自動(dòng)報(bào)警并調(diào)節(jié)。如某鎳合金發(fā)電站用遠(yuǎn)程監(jiān)控系統(tǒng)，電壓波動(dòng) ±5% 時(shí)，系統(tǒng)自動(dòng)調(diào)勵(lì)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(dòng)機(jī)狀態(tài)監(jiān)測(cè)?

Engine condition monitoring

發(fā)動(dòng)機(jī)是核心，要監(jiān)測(cè)機(jī)油壓力、冷卻液溫度、轉(zhuǎn)速等。機(jī)油壓力低影響潤(rùn)滑，冷卻液溫度高易致發(fā)動(dòng)機(jī)過(guò)熱。通過(guò)壓力、溫度等傳感器傳輸數(shù)據(jù)，實(shí)現(xiàn)故障預(yù)警。某鈷合金廠在發(fā)動(dòng)機(jī)裝多個(gè)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(cè)?

Exhaust emission monitoring

發(fā)電時(shí)仍要監(jiān)測(cè)尾氣排放，安裝設(shè)備監(jiān)測(cè)二氧化硫、氮氧化物、顆粒物等濃度，確保達(dá)標(biāo)。超標(biāo)時(shí)排查燃燒、尾氣處理裝置等問(wèn)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(qiáng)監(jiān)測(cè)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(yùn)行區(qū)要設(shè)防火隔離帶，嚴(yán)禁煙火。安裝可燃?xì)怏w泄漏報(bào)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(gè)探測(cè)器，全方位監(jiān)測(cè)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.
