Automatic bed material adding system

Abstract

The invention belongs to the technical field of circulating fluidized bed boilers, and particularly relates to an automatic bed material adding system. The automatic bed material adding system comprises a slag bin, a first boiler, a second boiler, a variable-frequency electric feeder, a vibrating screen, a surge bin, a sending device and a conveying pipeline, a discharging pipe is fixed to the bottom of the slag bin, the variable-frequency electric feeder is mounted at the bottom of the discharging pipe, vibrating screen is connected to the bottom of the variable-frequency electric feeder, the surge bin is assembled at bottom of the vibrating screen, the sending device is arranged below the surge bin, a gas inlet pipe is connected to one end of a gas pipeline, a gas storage tank is mounted at the lower end of the gas inlet pipe in a matched mode, an air compressor is connected to one end of the gas storage tank, a gas inlet pipe is connected to the end, away from the air compressor, of the gas storage tank, a first air supplementing pipe is connected between the gas inlet pipe and an ash-air mixer, and a second air supplementing pipe is connected to the gas inlet pipe and the lower end of the conveying pipeline. The pressure difference can be met to the maximum extent, it is ensured that materials enter the pipeline after being fully fluidized, instantaneous pressure relief cannot be formed, and the fluidization effect cannot be reduced.

Description

Technical field[0001]The present invention relates to the technical field of circulating fluidized bed boilers, in particular to automatic bed adding systems.Background technique[0002]For existing circulating fluidized bed boilers, you must add a bed before starting the boiler, it is originally passed through a belt machine or a lifting ton bag, and the bed is sent to the boiler platform, and is added to the boiler in the boiler. The bed layer is formed at the bottom of the boiler, which is ignited, and the above method is serious and the labor intensity is high, and the current environmental needs are not satisfied.[0003]In order to solve the above problems, automatic bed adding systems are proposed in this application.Inventive content[0004](1) Application[0005]To solve the technical problem in the background art, the present invention proposes an automatic bed addition system.[0006](2) Technical program[0007]In order to solve the above problems, the present invention provides a m...

Problems solved by technology

[0002] For the existing circulating fluidized bed boiler, the bed material must be added before each boiler start-up. In the past, the bed material was sent to the boiler platform through a belt conveyor or hoisted ton bags, and then manually added to the furnace of the boiler. A bed material layer is formed at the bottom of the boiler, and when the furnace is ignited and started, the above methods cause serious dust and labor-intensive personnel, which are increasingly unable to meet the current environmental protection needs.
