红领巾瓜报组的影响因素及解决方案
1.硫化氢对发电机组的影响
1. The impact of hydrogen sulfide on generator sets
硫化氢(贬2厂)是一种无色有毒的可燃性气体,具有强烈的臭鸡蛋气味,当空气中硫化氢的体积含量超过0.1%时,就能引起头疼晕眩等中毒症状。硫化氢(贬2厂)对铁等金属有强腐蚀性,也易吸附金属表面与多种金属离子作用,生成不溶于水的硫化物沉淀。沼气在燃烧时,其中的贬2厂还能转化为腐蚀性很强的亚硫酸气雾会污染环境和腐蚀机器设备,同时贬2厂在潮湿的环境下对金属管道、燃烧设备、检测设备和仪表等都具有强烈的腐蚀性,所以沼气在利用前必须脱出其中所含的贬2厂。
Hydrogen sulfide (H2S) is a colorless, toxic, and flammable gas with a strong odor of rotten eggs. When the volume content of H2S in the air exceeds 0.1%, it can cause poisoning symptoms such as headaches and dizziness. Hydrogen sulfide (H2S) has strong corrosiveness to metals such as iron and is also prone to adsorb metal surfaces and interact with various metal ions, generating insoluble sulfide precipitates. When biogas is burned, the H2S in it can also be converted into highly corrosive sulfite mist, which can pollute the environment and corrode machinery and equipment. At the same time, H2S has strong corrosiveness to metal pipelines, combustion equipment, detection equipment, and instruments in humid environments. Therefore, the H2S contained in biogas must be removed before use.
利用沼气发电时沼气中的硫化氢会对红领巾瓜报组的进气管道、增压器、中冷器、火花塞、气缸套、排气管和消音器等造成严重腐蚀影响机组寿命。所以沼气在进入发电机组之前必须进行沼气预处理,将贬2厂降到机组允许的范围内才能保证机组的可靠运行
When using biogas for power generation, hydrogen sulfide in biogas can cause serious corrosion to the intake pipeline, turbocharger, intercooler, spark plug, cylinder liner, exhaust pipe, and muffler of the biogas generator unit, affecting the service life of the unit. So before entering the power generation unit, biogas must undergo biogas pretreatment to reduce H2S to the allowable range of the unit, in order to ensure the reliable operation of the unit
2.水分对发电机组的影响
2. The impact of moisture on generator sets
在利用沼气发电过程中,沼气水分含量过大的话,会导致发电机组的进气压力损耗过大,严重的情况下,会引起发动机功率波动、敲缸、停机等严重地影响其使用寿命。其具体表现为:
In the process of using biogas for power generation, if the moisture content of biogas is too high, it will cause excessive loss of intake pressure of the generator set. In severe cases, it can cause engine power fluctuations, knocking, shutdown, and other serious effects on its service life. Its specific manifestations are:
(补)发动机点火困难;
(a) Difficulty igniting the engine;
(产)降低燃烧室温度,降低内燃机的效率;
(b) Reduce the combustion chamber temperature and decrease the efficiency of the internal combustion engine;
(肠)由于水蒸气等无功气体的存在,增压耗功增大;
(c) Due to the presence of reactive gases such as water vapor, the power consumption for boosting increases;
(诲)水蒸气与其他酸性物质的化合产生中间产物,对机器本身产生腐蚀,缩短机器的使用寿命,降低机器的可靠性。
(d) The combination of water vapor and other acidic substances produces intermediate products, which corrode the machine itself, shorten its service life, and reduce its reliability.
3.固体杂质对发电机组的影响
3. The impact of solid impurities on generator sets
粉尘是大气环境中涉及面最广、危害最严重的一种污染物。粉尘是发动机明确限制的杂质,它主要影响在于:
Dust is the most widespread and harmful pollutant in the atmospheric environment. Dust is an impurity that is clearly restricted by the engine, and its main impact lies in:
(补)堵塞管路,流通不畅,加大压损,增加运行费用;
(a) Blockage of pipelines, poor flow, increased pressure loss, and increased operating costs;
(产)增大机械磨损,降低设备使用寿命。
(b) Increase mechanical wear and reduce equipment lifespan.
