Novel fluidized bed roaster

Abstract

The invention discloses a novel fluidized bed roaster. The fluidized bed roaster comprises a box body, a slag tapping structure and a screening structure, wherein supporting legs are symmetrically distributed at the left end and the right end of the lower surface of the box body; a supporting plate is arranged between the two supporting legs; heat insulation plates are evenly distributed in the box body; a boiling chamber is arranged between every two adjacent heat insulation plates; an arc-shaped plate is arranged at the upper end of the boiling chamber at the left end; a heat absorption plate is arranged on the rear wall face of the box body; a support is arranged at the upper end of the left side face of the box body; an air blower is arranged at the rear end of the left side of the upper surface of the supporting plate; the front end of an air outlet pipe arranged at the upper end of the rear side face of the box extends into the box body; the air blower is connected to an air inlet of the air outlet pipe through an air pipe; and the slag tapping structure is arranged at the lower end of the box body and is fixedly connected to the supporting plate. According to the novel fluidized bed roaster, large coal briquettes are blocked, the combustion quality is guaranteed, the balance of heat in the box body is guaranteed, efficient combustion is achieved, humidifying operation isconducted on ash, automatic slag tapping is conducted, and the operation safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a novel fluidized fluidized furnace. Background technique [0002] A boiler is a kind of energy converter. It is a device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to a certain parameter. In industry, the fluidized bed furnace is also a common equipment. One is named after the air blows the coal particles up and down when burning coal, like boiling water. The thermal conductivity is high, and low-quality coal or gangue can be burned. The working principle of the fluidized bed furnace is to break the coal into coal particles, and send them to the furnace air distribution plate at a uniform speed through the coal feeder. The air distribution plate and the equal pressure air box are connected as a whole. The high-pressure wind from the bellows is injected into the furnace through the many small holes ...

Problems solved by technology

The thermal conductivity is high, and low-quality coal or gangue can be burned. The working principle of the fluidized bed furnace is to break the coal into coal particles, and send them to the furnace air distribution plate at a uniform speed through the coal feeder. The air distribution plate and the equal pressure air box are connected as a whole. The high-pressure wind from the bellows is injected into the furnace through the many small holes in the air distribution plate. The wind injected from all sides lifts the coal particles and the furnace charge. The flow dresser boils and burns, from large to small until it burns out, but the general fluidized fluidized furnace cannot guarantee the size of the coal block when it is working, and the internal heat cannot be evenly distributed. The ash generated is collected and processed by the staff, which improves the operation dangerous, so we need to design a new fluidized furnace to solve these problems
