System for conveying economizer ash

Abstract

The invention discloses a system for conveying economizer ash and belongs to the technical field of treatment of economizer ash. The system for conveying the economizer ash comprises a slag well; a dry slag extractor is arranged beside the slag well and conveys materials into a bucket type elevator; the bucket type elevator conveys the materials into a slag bin; the top of the slag bin is provided with a bag dust collector; the slag bin is simultaneously connected with the bottoms of a plurality of economizer bin pumps; and the plurality of economizer bin pumps are connected to an air source simultaneously. The system for conveying the economizer ash has a simple structure, is convenient to use, and low in cost, and can run reliably, and effectively avoid the phenomenon that an economizerash pipe directly enters the slag bin and cyclone is formed in the slag bin, so that dry slag and economizer ash can be collected and stored and the air inlet of the slag bin and the stable running of the air discharging can be controlled well, and pressure or vacuum in the slag bin is prevented from gathering; therefore, the using safety is guaranteed; and the conveying distance is short.

Description

technical field [0001] The invention relates to the processing technology of coal economizer ash, in particular to a conveying system of coal economizer ash. Background technique [0002] The economizer is a component arranged in the flue at the tail of the boiler to heat the feed water. Its function is to absorb part of the heat in the flue gas at the tail of the boiler, reduce the exhaust gas temperature, and save fuel. Therefore, the economizer ash has the characteristics of high temperature, coarse particles, and difficulty in long-distance pneumatic transportation. In the past, due to the unreasonable design of the transportation system and the long distance to the ash storage, the energy consumption of the system was high, and the operation effect was low. It is not ideal, and there are often problems such as blocked pipes, large system air consumption, and severely worn pipes. At present, the conveying system of the economizer ash is usually transported to the fly as...
