济柴为您讲述瓦斯发电机组的污染排放控制方法

返回 2021.05.20 来源:http://www.huannengpower.com
经济快速发展带来的环境污染唤醒了人们对于环境保护的重视。气体排放是发电机组污染排放的来源,为了响应环保号召,众多业内人士大刀阔斧改良发电机设计,以降低排放污染,今天济柴就来针对这一问题谈谈自己的观点。
The environmental pollution caused by the rapid economic development awakens people's attention to environmental protection. Gas emission is the source of pollution emission of generator set. In response to the call of environmental protection, many people in the industry have greatly improved the generator design to reduce the emission pollution. Today, jichai will talk about its own views on this issue.
瓦斯发电机组主要是通过进气系统将经过灰尘、杂质过滤的空气送入气缸内,因此,只要对进气系统进行改进,控制进入的空气量便能有用控制燃烧后的空气污染程度。海兴动力认为,以下两种方法是可行的:
The gas generator unit mainly sends the air filtered by dust and impurities into the cylinder through the air intake system. Therefore, as long as the air intake system is improved and the air quantity is controlled, the air pollution degree after combustion can be effectively controlled. Haixing power believes that the following two methods are feasible:
瓦斯发电机组
1、可采用可变涡流进气系统。由于进气涡流强度对NOx的排放影响较大,采用可变涡流进气系统的方式依据转速和负荷的变化来控制涡流强度,可在不牺牲经济性的情况下降低发电机组运行中NO。的生成量。
1. Variable swirl intake system can be used. Because the intake swirl intensity has a great influence on NOx emission, the variable swirl intake system is used to control the swirl intensity according to the change of speed and load, which can reduce the no emission in the operation of the generator without sacrificing the economy. The amount of production.
2、采用多气门技术(通常采用每缸四气门:进气门和排气门各2个)可扩大进、排气门的总流通截面积,充量系数增加,且喷油器可垂直布置在汽缸轴线上,有利于燃油在燃烧室空间中均匀分布,其混合气形成和燃烧条件大为改善,使放热规律更为合理,尾气排放中NOx的排放下降,CO的排放也有所减少,而且炭烟在大负荷时也明显下降。
2. The multi valve technology (usually four valves per cylinder: two inlet valves and two exhaust valves) can enlarge the total flow area of inlet and exhaust valves, increase the charge coefficient, and the injector can be vertically arranged on the cylinder axis, which is conducive to the uniform distribution of fuel in the combustion chamber space, greatly improve the mixture formation and combustion conditions, and make the heat release law more reasonable, In the exhaust emission, NOx emission and CO emission are reduced, and soot emission is also significantly reduced under heavy load.
以上两种方法是通过改良瓦斯发电机组技术而达到控制污染排放的目的的,而对于无法做到这一点的普通用户们,仍然可以在能力范围内降低发电机组的污染,例如,给进气管喷水或乳化柴油来促进油料的燃烧,燃烧充分的柴油所排放出的有害气体就会减少。
The above two methods achieve the purpose of controlling pollution emission by improving the technology of gas generator set. For ordinary users who can't do this, the pollution of generator set can still be reduced within the scope of their ability. For example, spray water on the intake pipe or emulsified diesel to promote the combustion of oil, and the harmful gas emitted by fully burned diesel will be reduced.
