系统水路和气路控制结构 Water and air control structure of dry fog dust suppression system
内置调节阀，将输送来的气、水调节到合适压力和流量输送到干雾喷头组件。 The water vapor spray box and sprayer assembly receives the gas and water delivered by the dry fog dust suppression host , and then adjusts the delivered gas and water to the appropriate pressure and flow through the dry fog control box with a built-in regulating valve to the dry fog nozzle. Components.
The nozzle receives the high-pressure water and gas from the water and gas pipeline, generates a dry mist with a particle size similar to the size of the dust through the atomizing nozzle, and then adjusts the spray direction by the universal joint to transport the dry mist to the dust production point. The dust passes through the dry mist adsorption, After condensation, dust clusters are formed to settle under the effect of gravity to achieve the purpose of suppressing dust.
PLC电路设计。 The dry fog control box should have local control and remote wake-up host startup functions, and the electrical design should use PLC circuit design. 通过皮带滚筒转动传感器及煤流传感器的是否发出脉冲信号采集皮带的启停状态，由干雾控制箱将这些开关量信号通过PLC进行数据处理后，以电码的形式实时通讯，将数据传输到微米级喷雾主机内置PLC，再由干雾控制箱通过通讯，在接收到输出信号后立即输出，驱动电磁阀并将电磁阀的运行状态发送给微米级喷雾主机PLC， 干雾控制箱可实现自动控制功能和手动就地控制功能，每个治理点应设置一套干雾控制箱 。 The dry fog control box collects the start and stop status of the belt through the pulse signal of the belt drum rotation sensor and the coal flow sensor. After the dry fog control box processes these digital signals through the PLC, it communicates in real time in the form of a code. The data is transmitted to the built-in PLC of the micron-level spray host, and then communicated by the dry-fog control box . After receiving the output signal, it outputs the output immediately, drives the solenoid valve and sends the operating status of the solenoid valve to the micro-level spray host PLC, the dry-fog control box. It can realize automatic control function and manual local control function. A set of dry fog control box should be set at each treatment point.
应具有吹扫排水功能，可以实现自动和手动排空水路管线中积水的功能，干雾抑尘系统在气管管线最低处应至少设置 1个自动排水装置，雾博应在图纸上详细标注泄水阀的位置并在方案内详细说泄水阀的工作流程和阀门选型。 The dry fog control box should have the function of purging and draining water, which can realize the function of automatically and manually emptying the water accumulated in the water pipeline. The dry fog dust suppression system should be provided with at least one automatic drainage device at the lowest point of the air pipe. The position of the drain valve is marked in detail and the work flow and valve selection of the drain valve are detailed in the plan.
采用高压气水混合喷雾形式。 The control box of the dry fog dust suppression system adopts a high-pressure gas-water mixed spray form. , 尘埃颗粒随气流运动时与水雾颗粒发生碰撞、吸附、凝结，形成的尘埃团在重力作用下降落，从而达到抑制尘埃的目的。 The dry fog dust suppression system generates water mist particles with a particle size similar to the dust particle size. The principle is that the maximum probability of adsorption, filtration, and condensation when the water mist particles are close to the dust particle size is the principle . When the dust particles move with the airflow, they collide with the water mist particles. The dust particles formed by adsorption and condensation drop under the action of gravity, so as to achieve the purpose of suppressing the dust.
应能在高温、高湿度的环境条件下正常运行。 The dry fog dust suppression device / control box should be able to operate normally under high temperature and high humidity environmental conditions. The dry fog dust suppression device should be able to handle dust of various coal types, including high-volatile coal dust.
