Slag falling system of garbage boiler

Abstract

The invention discloses a slag falling system of a garbage boiler. The slag falling system comprises a square-opening directional hood, a columnar hood or a mushroom-type hood, an air distributing plate, a slag falling pipe, a casting material and a slag outlet and also comprises a duckbill-type directional hood, wherein the duckbill-type directional hood, the square-opening directional hood and the mushroom-type hood are distributed on the outer side of the slag outlet from inside to outside in a layered manner; the square-opening directional hood and the duckbill-type directional hood are distributed at the near position close to the slag outlet at an interval in a staggering manner and form a step shape with up-down fall; the mushroom-type hood is distributed on the outer side of the slag outlet; the duckbill-type directional hood is completely buried in the casting material, while the square-opening directional hood and the mushroom-type hood extend out of the surface of the casting material; all the hoods are vertically inserted into opened holes of the air distributing plate. The slag falling system disclosed by the invention has the beneficial effects that the duckbill-type directional hood, the square-opening directional hood and the mushroom-type hood are combined and distributed, so that the flowing space of furnace slag is enlarged, the winding probability of iron wires at a slag falling port is reduced, the fluidization air quantity of the outlet is increased, and the whole device is beneficial to forming good working condition with uniform fluidization and disturbance at the upper part and smooth drainage and deslagging at the lower part.

Description

Technical field: [0001] The invention relates to a slag dropping system in the technical field of garbage incineration boiler equipment. Background technique: [0002] Due to the structural design of the slag removal device of the existing garbage incinerator, sometimes dense columnar hoods or mushroom-shaped hoods are arranged around the slag outlet. The accumulation and blockage at the slag outlet increases the difficulty of slag removal; there is also a single row of horizontal directional air caps near the slag outlet, and the columnar air caps on the outer side are dense. This structure solves the problem of poor slag fluidity. , the slag flow space is small, and it is easy to cause the winding and pulling of the iron wire, which affects the stable operation of the boiler; the above-mentioned slag removal devices only consider the movement of the slag to the slag outlet and do not consider the problem of the slag entering the slag outlet, and the existing garbage The p...
