養(yǎng)殖場的糞污、餐廚垃圾、污水處理廠的污泥……這些令人頭疼的有機廢物，在環(huán)能沼氣發(fā)電機組面前，卻是一筆寶貴的“能源財富”。環(huán)能沼氣發(fā)電機組通過“厭氧發(fā)酵產(chǎn)沼—氣體凈化—燃燒發(fā)電”的全鏈條技術(shù)，將有機廢物轉(zhuǎn)化為清潔電能，實現(xiàn)了“廢物”到“寶藏”的華麗蛻變。

Farm manure, kitchen waste, sewage treatment plant sludge... These headache inducing organic wastes are valuable "energy wealth" in front of the environmental energy biogas generator set. The environmental energy biogas generator unit uses the full chain technology of "anaerobic fermentation biogas production gas purification combustion power generation" to convert organic waste into clean electricity, achieving a magnificent transformation from "waste" to "treasure".

環(huán)能沼氣發(fā)電機組的核心工作流程分為三個環(huán)節(jié)。首先是厭氧發(fā)酵產(chǎn)沼——有機廢物在密閉的厭氧發(fā)酵罐中，在微生物的作用下分解產(chǎn)生沼氣，主要成分為甲烷（50%-70%）和二氧化碳。其次是沼氣凈化——發(fā)酵產(chǎn)生的粗沼氣含有硫化氫、水分和雜質(zhì)，需經(jīng)脫硫、脫水、除塵等預處理，使其達到發(fā)電機組要求的品質(zhì)。第三是燃燒發(fā)電——凈化后的沼氣進入燃氣內(nèi)燃發(fā)電機組，在氣缸內(nèi)與空氣混合燃燒，推動活塞做功發(fā)電。小紅門再生水廠沼氣發(fā)電項目便采用這一模式，新建4臺1200kW燃氣內(nèi)燃發(fā)電機組，總裝機4.8MW，配套4臺余熱蒸汽鍋爐。

The core workflow of the environmental energy biogas generator set is divided into three stages. Firstly, anaerobic fermentation produces biogas - organic waste is decomposed by microorganisms in a closed anaerobic fermentation tank to produce biogas, mainly composed of methane (50% -70%) and carbon dioxide. Next is biogas purification - the crude biogas produced by fermentation contains hydrogen sulfide, moisture, and impurities, and needs to be pre treated with desulfurization, dehydration, dust removal, etc. to meet the quality requirements of the generator set. The third is combustion power generation - purified biogas enters the gas-fired internal combustion generator set, mixes with air in the cylinder for combustion, and drives the piston to do work and generate electricity. The biogas power generation project of Xiaohongmen Reclaimed Water Plant adopts this mode. Four 1200kW gas-fired internal combustion generating units with a total installed capacity of 4.8MW and four waste heat steam boilers are to be built.

環(huán)能沼氣發(fā)電機組在能源綜合利用方面表現(xiàn)出色。發(fā)電過程中產(chǎn)生的高溫煙氣進入余熱鍋爐生產(chǎn)蒸汽，高、低溫冷卻水分別用于采暖及生產(chǎn)補水加熱，非常大限度提升了綜合能源利用效率。樂清寶通1200kW沼氣發(fā)電項目設(shè)計年處理易腐垃圾3萬噸，產(chǎn)沼氣600萬立方米，年發(fā)電850萬度，可節(jié)約標煤約2600噸，減排二氧化碳3.5萬噸。這種“垃圾廢棄物—綠色能源—資源循環(huán)”的閉環(huán)體系，是能源轉(zhuǎn)化與廢棄物處置的有機結(jié)合。從養(yǎng)殖場糞污到餐廚垃圾，從污水處理廠污泥到農(nóng)業(yè)廢棄物，環(huán)能沼氣發(fā)電機組正在將有機廢物“吃干榨凈”，讓每一份有機質(zhì)都釋放出非常大的能源價值。

The environmental energy biogas generator set has shown outstanding performance in comprehensive energy utilization. The high-temperature flue gas generated during the power generation process enters the waste heat boiler to produce steam, and the high and low-temperature cooling water are used for heating and production water replenishment heating respectively, maximizing the comprehensive energy utilization efficiency. The Yueqing Baotong 1200kW biogas power generation project is designed to process 30000 tons of perishable waste annually, produce 6 million cubic meters of biogas, generate 8.5 million kilowatt hours of electricity annually, save about 2600 tons of standard coal, and reduce carbon dioxide emissions by 35000 tons. This closed-loop system of "garbage waste green energy resource recycling" is an organic combination of energy conversion and waste disposal. From farm manure to kitchen waste, from sewage treatment plant sludge to agricultural waste, environmental energy biogas generators are "squeezing out" organic waste, allowing every organic matter to release its maximum energy value.
