正压稀相气力输灰系统是以罗茨鼓风机产生的气流为载体，将小颗粒、粉末、物料输送到指定出料点的气力输送系统。输送管道灵活、密闭、多粉尘。更少泄漏，更节能，更高效，更容易操作，更易于维护，使大批量物料的运输，先进的自动化，有效降低员工运输、包装和装卸成本。此外，正压气力输送系统可同时处理物料。执行各种物料或化学工艺流程，包括物料混合、粉碎、分类、干燥、冷却等工艺处理。

The positive pressure dilute phase pneumatic ash conveying system is a pneumatic conveying system that uses the airflow generated by a Roots blower as a carrier to transport small particles, powders, and materials to designated discharge points. The conveying pipeline is flexible, sealed, and dusty. Less leakage, more energy saving, more efficient, easier to operate, and easier to maintain, enabling the transportation of large quantities of materials. Advanced automation effectively reduces employee transportation, packaging, and loading and unloading costs. In addition, the positive pressure pneumatic conveying system can process materials simultaneously. Execute various material or chemical processes, including material mixing, crushing, classification, drying, cooling, and other process treatments.

气力输灰系统参数:本系统主要采用罗茨风机作为动力源，风速:15m/s-30m/s，料速:8m/s-15m/s，输送能力:1-100t/h，输送距离150米(采用多级供电，可达1000m)。

Parameters of pneumatic ash conveying system: This system mainly uses Roots blower as the power source, with wind speed of 15m/s-30m/s, material speed of 8m/s-15m/s, conveying capacity of 1-100t/h, and conveying distance of 150 meters (using multi-stage power supply, up to 1000m).

在正压稀相气力输灰系统的配置中，罗茨鼓风机通常用作气源。罗茨风机位于系统的前端，风机出口风将物料喷入远程接收仓，下面介绍一下正压稀相气力输灰系统构成与优缺点。

In the configuration of positive pressure dilute phase pneumatic ash conveying system, Roots blower is usually used as the gas source. The Roots blower is located at the front end of the system, and the outlet air of the blower sprays the material into the remote receiving bin. Below is an introduction to the composition, advantages, and disadvantages of the positive pressure dilute phase pneumatic ash conveying system.

正压稀相气力输灰系统主要由罗茨风机、输送系统(旋转给料机、连续输送泵、管道、开关阀、阀门设备等)、储灰系统(灰筒仓、屋面集尘器、干灰)等构成。气源压力低，以罗茨风机(散货机、湿化混合器、阀表等)为主要动力，通过罐车或汽车管道输送。其优点是管道内粉尘浓度低，气力输灰系统运量高，能耗低，设备磨损低，维护成本低。

The positive pressure dilute phase pneumatic ash conveying system mainly consists of Roots blower, conveying system (rotary feeder, continuous conveying pump, pipeline, switch valve, valve equipment, etc.), ash storage system (ash silo, roof dust collector, dry ash), etc. The gas source pressure is low, mainly powered by Roots blowers (bulk carriers, humidification mixers, valve gauges, etc.), and transported through tank trucks or automotive pipelines. Its advantages are low dust concentration in the pipeline, high transportation capacity of the pneumatic ash conveying system, low energy consumption, low equipment wear, and low maintenance costs.
