针对我国目前使用的铁路直接排放式厕所不雅观不文明、污染环境、浪费水等问题,设计了真空厕所系统。真空厕所基于真空运输理论,利用真空泵抽取真空室、纳污罐和输送管道内的空气,降低其中的大气压力,一般在0.03MPa～0.05MPa范围内,接入便器,利用界面阀控制便器与管道通断,将粪便吸入至纳污罐,实现了粪便污物的抽吸。由于其冲洗水少,不易堵塞管路,整套系统密封,有效控制臭气外漏,不易污染环境,故其是新一代环保产品。研究了铁路列车真空厕所系统工作原理和工作过程,设计了其控制电路。
In view of the unscrupulous and uncivilized railways that are currently used in our country, polluting the environment and wasting water, a vacuum toilet system is designed. Vacuum toilet based on the theory of vacuum transport, the use of a vacuum pump to extract the vacuum chamber, polluting the tank and the air inside the pipeline, reducing the atmospheric pressure, generally within the range of 0.03MPa ~ 0.05MPa, access to the toilet, the use of interface valve control toilet and pipe On and off, the stool inhalation to the pollutant tank, to achieve the feces of soil suction. Because of its less flushing water, easy to plug the pipeline, the entire system seal, effective control of odor leakage, not easy to pollute the environment, so it is a new generation of environmentally friendly products. The working principle and working process of the vacuum toilet system of railway train are studied, and the control circuit is designed.
