摘要
将低浓度瓦斯用于发电时,水环式真空泵出口瓦斯含水量较大,液态水进入发电机组内部会增加热耗,同时锈蚀设备,影响机组开机率和发电效率。针对这一问题,分析了目前常用的脱水方法的原理和工艺技术,综合考虑脱水效率和阻力因素,提出丝网脱水方案,并进行了相关设计,研究其脱水效果、阻力,以及对发电效率的影响。研究结果表明,丝网分离器可以有效脱除瓦斯气中的水分,经济效益较好。
When the low--concentration gas is used for pow-er generation, the moisture in the gas at the outlet of the water-ring vacuum pump is larger, the liquid water entering into the power generator unit will increase the heat consumption, rust the equipment and affect the unit boot rate and power generation efficiency. To counter these problems, analysis was made on the principle and process technology of the cominonly-used dewatering methods, the dewatering efficiency and resistance factors were all taken into overall consideration, the wire-mesh dewatering scheme was put forward and relevant design was carried out so as to study the influence of the dewatering effect and resistance on the power generation efficiency. The study results showed that the wire-mesh seperator can effictively remove the moisture in the gas, so it has better economic benefit.
