Problems solved by technology

[0002] The ash and slag discharged from the boilers of coal-fired power plants have been developed and utilized as a resource. Therefore, the dry ash of the boiler flue gas dust collector generally adopts the pneumatic ash removal method. Pneumatic ash removal system is difficult to meet the requirements of economy, practicality, reliability and energy saving. The main problems are as follows:
It is the main reason for the large number of warehouse pumps and low conveying efficiency of the existing pneumatic ash removal system
[0005]3. The conveying method of all warehouse pumps is to convey the comp

Abstract

The invention discloses a positive-negative integrated conveying system device of a multifunctional pump, comprising a multifunctional bin pump, a negative pressure ash loading device of the multifunctional pump and a positive pressure conveying device of the multifunctional pump. In the invention, a set of bin pumps of the conveying system device can be connected with a plurality of ash hoppers without an intermediate ash silo; and ash is conveyed to a terminal ash silo at one step, a large amount of materials and equipment can be saved and the discharge speed of the bin pump can be adjusted, thereby the conveying system device is not easy to block the pneumatic conveying system device of the pipe.

Description

technical field [0001] The invention relates to a powder material pneumatic conveying system device, in particular to a large and medium-sized coal-fired power plant pneumatic ash removal system device, and a limestone powder pneumatic conveying system device for a boiler flue gas desulfurization system. Background technique [0002] The ash and slag discharged from the boilers of coal-fired power plants have been developed and utilized as a resource. Therefore, the dry ash of the boiler flue gas dust collector generally adopts the pneumatic ash removal method. Pneumatic ash removal system is difficult to meet the requirements of economy, practicality, reliability and energy saving. The main problems are as follows: [0003] 1. The domestic coal-fired power plants have larger and larger single-unit capacity (such as a single-unit capacity of 1000MW), the increase in the number of ash hoppers for boiler flue gas dust collectors, the increase in ash volume, and the long transp...
