在煤化工生產(chǎn)過程中，會產(chǎn)生大量含有可燃成分的尾氣，這些尾氣若直接排放，不僅造成能源浪費(fèi)，還可能加劇環(huán)境負(fù)擔(dān)。煤化工尾氣發(fā)電機(jī)組的出現(xiàn)，為這類尾氣的資源化利用提供了有效途徑，通過將尾氣中的化學(xué)能轉(zhuǎn)化為電能，實(shí)現(xiàn)了環(huán)保與節(jié)能的雙重效益。

　　In the production process of coal chemical industry, a large amount of exhaust gas containing combustible components will be generated. If these exhaust gases are directly discharged, it not only causes energy waste, but also may exacerbate the environmental burden. The emergence of coal chemical tail gas power generation units provides an effective way for the resource utilization of such tail gas. By converting the chemical energy in the tail gas into electrical energy, it achieves dual benefits of environmental protection and energy conservation.

　　從工作原理來看，煤化工尾氣發(fā)電機(jī)組主要由燃?xì)獍l(fā)動機(jī)、發(fā)電機(jī)、尾氣處理系統(tǒng)及控制系統(tǒng)等部分構(gòu)成。首先，煤化工生產(chǎn)中產(chǎn)生的尾氣（如含有一氧化碳、氫氣、甲烷等可燃?xì)怏w）經(jīng)過凈化處理，去除其中的粉塵、硫化物、焦油等雜質(zhì)，避免對發(fā)動機(jī)造成腐蝕或堵塞。凈化后的尾氣進(jìn)入燃?xì)獍l(fā)動機(jī)，與空氣按一定比例混合后在氣缸內(nèi)燃燒，產(chǎn)生的熱能推動活塞運(yùn)動，帶動曲軸旋轉(zhuǎn)，進(jìn)而驅(qū)動發(fā)電機(jī)運(yùn)轉(zhuǎn)，將機(jī)械能轉(zhuǎn)化為電能。整個過程中，控制系統(tǒng)實(shí)時監(jiān)測尾氣流量、燃燒效率、發(fā)電功率等參數(shù)，確保機(jī)組穩(wěn)定運(yùn)行。

　　From the perspective of working principle, the coal chemical tail gas generator set mainly consists of gas engine, generator, tail gas treatment system, and control system. Firstly, the exhaust gas generated in coal chemical production (such as combustible gases containing carbon monoxide, hydrogen, methane, etc.) is purified to remove impurities such as dust, sulfides, tar, etc., to avoid corrosion or blockage of the engine. The purified exhaust enters the gas engine, mixes with air in a certain proportion, and burns in the cylinder. The generated heat energy drives the piston to move, drives the crankshaft to rotate, and then drives the generator to operate, converting mechanical energy into electrical energy. Throughout the entire process, the control system monitors parameters such as exhaust flow rate, combustion efficiency, and power generation in real-time to ensure stable operation of the unit.

　　在應(yīng)用價值方面，這類發(fā)電機(jī)組實(shí)現(xiàn)了 “變廢為寶” 的資源化利用。對于煤化工企業(yè)而言，利用尾氣發(fā)電可補(bǔ)充企業(yè)內(nèi)部用電需求，降低對外部電網(wǎng)的依賴，減少電費(fèi)支出；多余的電能還可并入公共電網(wǎng)，創(chuàng)造額外的經(jīng)濟(jì)收益。從環(huán)保角度看，尾氣中的可燃成分被充分燃燒利用，減少了有毒有害氣體的排放，降低了對大氣環(huán)境的污染，同時也減少了溫室氣體排放，符合綠色發(fā)展的要求。此外，發(fā)電機(jī)組的余熱還可回收利用，用于供暖或生產(chǎn)過程中的加熱環(huán)節(jié)，進(jìn)一步提高能源利用效率，形成能源梯級利用的循環(huán)系統(tǒng)。

　　In terms of application value, this type of generator set has achieved the resource utilization of "turning waste into treasure". For coal chemical enterprises, utilizing exhaust gas for power generation can supplement internal electricity demand, reduce dependence on external power grids, and lower electricity bills; Excess electricity can also be integrated into the public grid, creating additional economic benefits. From an environmental perspective, the combustible components in exhaust gases are fully burned and utilized, reducing the emission of toxic and harmful gases, lowering pollution to the atmospheric environment, and also reducing greenhouse gas emissions, which meets the requirements of green development. In addition, the waste heat from the generator set can also be recovered and utilized for heating or heating in the production process, further improving energy utilization efficiency and forming a circular system of energy cascade utilization.

　　技術(shù)特點(diǎn)上，煤化工尾氣發(fā)電機(jī)組需適應(yīng)尾氣成分復(fù)雜、熱值波動大的特點(diǎn)，因此在設(shè)計上具備較強(qiáng)的適應(yīng)性。發(fā)動機(jī)通常采用特殊的燃燒系統(tǒng)，可靈活應(yīng)對不同組分的燃?xì)?，保證燃燒充分且穩(wěn)定；凈化系統(tǒng)則根據(jù)尾氣的具體成分定制，如針對高硫尾氣配備高效脫硫裝置，針對含塵量高的尾氣強(qiáng)化除塵環(huán)節(jié)。同時，機(jī)組的自動化程度較高，具備自動啟停、故障診斷、遠(yuǎn)程監(jiān)控等功能，可減少人工干預(yù)，提高運(yùn)行可靠性。部分機(jī)組還采用模塊化設(shè)計，便于安裝、維護(hù)和擴(kuò)容，能根據(jù)尾氣排放量的變化調(diào)整發(fā)電規(guī)模。

　　In terms of technical characteristics, the coal chemical tail gas generator unit needs to adapt to the complex composition of tail gas and large fluctuations in calorific value, so it has strong adaptability in design. Engines usually use special combustion systems that can flexibly respond to different components of gas, ensuring sufficient and stable combustion; The purification system is customized according to the specific composition of the exhaust gas, such as equipping high-efficiency desulfurization devices for high sulfur exhaust gas and strengthening the dust removal process for exhaust gas with high dust content. At the same time, the unit has a high degree of automation, with functions such as automatic start stop, fault diagnosis, and remote monitoring, which can reduce manual intervention and improve operational reliability. Some units also adopt modular design for easy installation, maintenance, and expansion, and can adjust the power generation scale according to changes in exhaust emissions.

　　煤化工尾氣發(fā)電機(jī)組的推廣應(yīng)用，不僅為煤化工行業(yè)的節(jié)能減排提供了切實(shí)可行的解決方案，也為能源多元化利用開辟了新路徑。隨著技術(shù)的不斷進(jìn)步，這類機(jī)組的效率將進(jìn)一步提升，適用范圍也將更廣泛，在推動煤化工產(chǎn)業(yè)向低碳、循環(huán)方向發(fā)展中發(fā)揮重要作用。

With the continuous advancement of technology, the efficiency of such units will be further improved and their applicability will be wider, playing an important role in promoting the development of the coal chemical industry towards low-carbon and circular direction.
