Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。

The system uses PID controller and fuzzy controller to design automatic control loops, a study of fuzzy three-element feed-water control system for a CFB municipal waste incinerator is introduced. The incinerator is faced with problems such as large-scale fluctuation of furnace heat load and low regulation resolution of main control feed-water valve. The fuzzy logic control system is applied to modulate PI control parameters according to steam drum water level to fit fluctuated heat load, the inner and outer control loops are realized in an asynchronous way to effectively decrease regulation time and improve regulation precision.

针对垃圾炉炉膛负荷波动较大，同时给水调节阀门执行机构的调节精度较低的现状，在传统三冲量串级汽包水位控制方式的基础上，采用模糊控制策略对内、外串级回路的PI控制参数进行分区域调整，强调了PI参数在被控参量处于不同范围时的分离作用，同时内、外控制回路采用异步控制方式，浙江大学硕士学位论文从而有效地减小了被控参量的调节时间，提高调节精度，使水位波动控制在△为士12~范围内。
