Control system and method for heating waterway ball valves by using engine tail gas and sanitation truck
The invention discloses a control system and method for heating waterway ball valves by using engine tail gas and a sanitation truck. A reversing valve is arranged to achieve switching between the two states of normal tail gas emission and tail gas heating, and a gas storage tank is arranged to store high-temperature tail gas temporarily and convey the high-temperature tail gas to a plurality of blowing nozzles in a distribution mode. When the reversing valve is controlled to be switched to be communicated with the gas storage tank, the high-temperature tail gas is conveyed to the multiple paths of waterway high-pressure ball valves and air cylinder piston rods through the multiple blowing nozzles so as to heat the multiple paths of waterway high-pressure ball valves and the air cylinder piston rods, and recycling of the automobile tail gas is achieved. Besides, workers do not need to perform operation outdoors for a long time, the labor intensity of the workers is reduced, and the unfreezing efficiency is improved. Meanwhile, the reversing valve, the gas storage tank and the blowing nozzles are all detachably mounted and can be mounted during operation in winter and dismounted during operation in other seasons, and use is flexible and convenient.
本发明公开了一种利用发动机尾气加热水路球阀的控制系统及方法、环卫车，其通过设置换向阀来实现尾气正常排放和尾气加热两种状态之间的切换，设置储气罐来临时存储高温尾气并分流输送多个吹嘴，当控制换向阀切换至与储气罐导通时，高温尾气经多个吹嘴输送至多路水路高压球阀和气缸活塞杆处，以对多路水路高压球阀和气缸活塞杆进行加热，实现了汽车尾气的回收利用，并且，无需工作人员长时间在室外操作，降低了工作人员的劳动强度，提高了解冻效率。同时，换向阀、储气罐和吹嘴均采取可拆卸的安装方式，在冬季作业时可以装上，而在非冬季作业时可以拆下，使用灵活方便。
