Description
技术领域 technical field
本实用新型涉及一种垃圾渗滤液处理的沼气处理装置，具体涉及一种沼气过滤防回火装置。 The utility model relates to a methane treatment device for garbage leachate treatment, in particular to a methane filtering anti-backfire device.
背景技术 Background technique
垃圾处理过程中，会有垃圾渗滤液收集，其会产生大量的沼气，如果采用风加压，其有可能将厌氧池抽成负压使空气进入，沼气和空气混合比例达到一定程度将会造成爆炸，因此要求厌氧池在正压状态运行。 During the garbage disposal process, there will be garbage leachate collection, which will generate a large amount of biogas. If wind pressurization is used, it may pump the anaerobic tank into negative pressure to allow air to enter. The mixing ratio of biogas and air will reach a certain level. Cause an explosion, so the anaerobic pool is required to operate under positive pressure.
同时，因沼气中水蒸气含量较高，故在管道中流动时随着温度的逐渐降低不断有冷凝水析出，这就要求安装气水分离器以降低沼气湿度，减少对管道及设备的腐蚀，并防止凝结水对气路的阻塞。 At the same time, due to the high content of water vapor in the biogas, condensed water will continue to precipitate as the temperature gradually decreases when flowing in the pipeline. This requires the installation of a gas-water separator to reduce the humidity of the biogas and reduce the corrosion of pipelines and equipment. And prevent condensed water from blocking the gas path.
沼气是易燃易爆气体，在管路上必须设置阻火器，防止因明火沿沼气管道流窜而引起厌氧池及其他重要附属设施的爆炸。 Biogas is a flammable and explosive gas, and a flame arrester must be installed on the pipeline to prevent the explosion of the anaerobic pond and other important auxiliary facilities caused by the open flame flowing along the biogas pipeline.
