Abstract

The invention relates to the technical field of economizer ash conveying systems, in particular to a novel non-rigid expansion joint. Comprising an economizer, an upper feeding device, an expansion joint, a lower feeding device, a sending tank and a discharging device. The economizer, the upper feeding device, the expansion joint, the lower feeding device, the sending tank and the discharging device are connected in sequence; an operation dial plate is further arranged on the surface of the sending tank. The invention aims to provide a novel non-rigid expansion joint aiming at the defects in the prior art, and the effect of effectively controlling flying dust through arrangement and functions of a field equipment system under the condition of a fault of an ash conveying system or an emergency condition is achieved.

Description

technical field [0001] The invention relates to the technical field of an ash conveying system of an economizer, in particular to a novel non-rigid expansion joint. Background technique [0002] The sending tank of the economizer is very important in the ash conveying system. It is connected to the lower part of the ash hopper of the economizer, and the ash powder in the economizer is transported to the ash storage through compressed air, while the economizer discharge bag is It is the hub between the ash hopper and the sending tank. [0003] In recent years, the failure rate of the double casing soot blowing system of the economizer is high, which seriously affects the economical and safe operation of the equipment. Among them, the breakage rate of the economizer feeding bag is the highest, which reduces the commissioning rate of the system unit. During the ash conveying system of the economizer ash hopper, ash leakage often occurs, and a large amount of ash powder flows ...
