Abstract

The invention provides an automatic deslagging method and system for a fluidized bed combustion boiler. The method comprises the steps that a pressure sensor is mounted in a bellows of an air blower of the fluidized bed combustion boiler, a deslagging pipe is provided with an electric gate plate, and a high-temperature-resistant wear-resisting pipeline and a conveying device are mounted under the electric gate plate; under a working condition, the pressure in the bellows is measured when bed charge of the required thickness is burnt by the fluidized bed combustion boiler, and the pressure is used as standard pressure; the pressure of the bellows in operation is measured, and when the pressure of the bellows in operation is higher than the standard pressure, the electric gate plate is opened for deslagging, and slag is conveyed to a slag field through a conveying device; and when the pressure of the bellows in operation is equal to the standard pressure, deslagging is stopped, and the process is cycled in this way. According to the automatic deslagging method and system for the fluidized bed combustion boiler, the problem that efficiency is low in traditional timed manual deslagging is solved, the automation degree of the fluidized bed combustion boiler is improved, manpower is saved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the auxiliary system of a gypsum board factory, in particular to an automatic slag discharge method and system for a fluidized fluidized furnace. Background technique [0002] The fluidized fluidized furnace is an important process equipment for heat supply in the gypsum board production line. The slag generated during the operation of the fluidized fluidized furnace in the gypsum board production line is accumulated in the fluidized fluidized furnace and discharged manually according to the process requirements, which wastes human resources. [0003] Therefore, how to automatically discharge fluidized furnace slag and improve production efficiency has become a problem that technicians need to consider. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automatic slag discharge method and system for fluidized fluidized furnace, which can automatically discharge slag...
