天热时常见城里洒水车出动。洒水后的街道,不仅让人感到特别凉爽,而且灰尘顿少,空气也变得新鲜。随着城市的不断改造,新开和拓宽重建的道路不少。在一些重点路段,应该考虑设置一系列的温度自动调控装置。例如,在广场上多设置点温度监控仪,监测并显示当地温度、污染程度、空气状况。如果这些指标中有一项或数项超标,就立即启动预先设计并安装在路边的喷水孔。水从喷孔中喷出时有多种变化,有的射向空中,有的就冲刷地面,还有的成雾状。这样,不仅可以降低地表的温度,缓解市区的热岛效应,而且可以冲刷地面灰尘和滞留在地面的汽车尾气,空气也可以得到净化。 Hot weather common city sprinkler. The streets after the watering, not only make people feel particularly cool, and less dust, the air has become fresh. With the constant transformation of cities, there are many new roads to open up and to broaden the reconstruction. In some key sections, should consider setting a series of automatic temperature control device. For example, more points in the square temperature monitor to monitor and display the local temperature, pollution, air conditions. If one or more of these indicators exceeds the standard, the pre-designed and installed water jet on the curb is activated. There are many changes in the water jet from the nozzle hole, and some shot in the air, and some washed the ground, and some into a mist. In this way, not only the surface temperature can be reduced and the heat island effect in the urban area can be alleviated, but also the dust on the ground and the car tailing on the ground can be washed away and the air can be purified.
