Problems solved by technology

[0003] The number of dust hoppers in the dust collector is usually large. If the traditional single-transmitter pneumatic conveying method is adopted, each transmitter needs to be separately equipped with an inlet valve and a discharge valve. The system configuration is relatively complicated, and the initial investment cost is high. The maintenance workload is also large
In addition, the traditional single-transmitter pneumatic conveying method needs back pressure conveying, the conveying flow rate is high, the equipment wears seriously, and the system operation reliability is low

Abstract

The invention relates to a pneumatic conveying system for fly ash of a dust collector. The system comprises a conveying device, an air source device and a pipeline device; the conveying device is connected with the air source device. According to the pneumatic conveying system of the fly ash of the dust collector, a conveyor mounted below an ash bucket is used for conveying the fly of the dust collector into an ash warehouse; the problems of complex configuration, high conveying energy consumption, serious wear of a pipeline and a valve, and large workload of operation and maintenance of the conveying system of the traditional dust collector can be solved, so that the ash conveying system of the dust collector is economic, practical and reasonable; the operation reliability of the system can also be greatly improved.

Description

technical field [0001] The invention relates to a pneumatic conveying system for powder materials, in particular to a pneumatic conveying system for dust collector fly ash. Background technique [0002] The electric power industry is an important basic industry of the national economy, and also a key industry, a leading industry, and a pillar industry in the national economic development strategy. From the comparison of power production and economic growth in various periods, in the years of continuous economic growth, the growth of power production exceeds the growth of GDP. my country's national conditions of resources determine that my country's energy structure is dominated by thermal power, supplemented by hydropower, supplemented by nuclear power and wind power, and the development of the power structure is very unbalanced. The new coal-fired boilers will generate a large amount of dust-laden flue gas every year. These dust-laden flue gases need to be separated by hig...
