The utility model provides a low-pressure dilute-phase pneumatic conveying device for boiler fly ash, which comprises a feeder, an ash collector hopper at the upper end of the feeder, a dust collector hopper at the upper end of the ash collector, and a dust collector hopper at the lower end of the feeder connected with the ash storage through a ash conveying pipe. An air chute is arranged between the ash hopper of the dust collector and the ash collector hopper, and an air chute at one end of the air chute. The dust collector is connected with the dust hopper of the dust collector, the other end of the air chute is connected with the ash hopper, and the ash hopper is connected with the dust hopper of the dust collector through the return pipe. The feeder is connected with the accelerator, one end of the accelerator is connected with the Roots blower, and the other end of the accelerator is connected with the ash depot through the ash conveying pipe. The roots blower of the utility model has the advantages of low compressed air pressure, low energy consumption, low operation cost, low compressed air pressure and light wear; several dust collectors share a set of feeders through an air chute; the system is simple, the investment is small, and the leakage point is small; the elbows of the ash conveying pipeline are made of wear-resisting lined ceramic elbows, which have good wear resistance and are not easy to wear. Loss of leakage.

一种锅炉粉煤灰低压稀相气力输送装置
本技术属于机械领域,具体地说涉及一种锅炉粉煤灰低压稀相气力输送装置。
技术介绍
在锅炉系统中需要对除尘器捕捉下的粉煤灰进行输送储存。目前气力输送是现在锅炉粉煤灰输送的主要方式。气力输送又分为高压浓相输送和低压稀相输送两种,高压浓相输送的特点是输送距离远能耗高,多适用于输送距离200米以上的场合;低压稀相输送的特点是能耗低运行可靠,多适用于输送距离200米以下的场合。但现有的低压稀相气力输送装置存在以下缺陷:一是每台除尘器灰斗下需要加装一套供料装置,系统复杂;二是输灰管道弯头处磨损较重易泄漏。
