Pulverized coal and coal cinder cleaning device for coal feeding port of coking furnace, and using method thereof

Abstract

The invention discloses a pulverized coal and coal cinder cleaning device for a coal feeding port of a coking furnace, and a using method thereof, and belongs to the technical field of coking furnaces. The pulverized coal and coal cinder cleaning device comprises a square cylinder, a dust removal net is fixedly mounted at the top of the square cylinder, a plurality of first fixing plates are fixedly mounted in the square cylinder, and a first material receiving inclined plate and a second material receiving inclined plate are fixed to the two opposite side faces of every two adjacent first fixing plates correspondingly. The dust removal net, the first material receiving inclined plate and the second material receiving inclined plate are arranged, and the maximum distance between the first material receiving inclined plate and first fixing plates and the maximum distance between the second material receiving inclined plate and the first fixing plates are controlled to be larger than half of the distance between every two adjacent first fixing plates. Therefore, pulverized coal cinder entering the tops of the first material receiving inclined plate and the second material receiving inclined plate along with hot air can completely fall onto the first material receiving inclined plate and the second material receiving inclined plate, cleaning and collecting of the pulverized coal cinder are achieved through the simple structure, the structure is simple, the use and maintenance cost is low, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of coking furnaces, and in particular relates to a pulverized coal and cinder cleaning device for a coal delivery port of a coking furnace and an application method thereof. Background technique [0002] Coking furnace, a furnace usually made of refractory bricks and refractory blocks, is used to make coal to produce coke, that is, a kiln for refining coke with coal. It is the main thermal equipment for coking. Modern coking furnace refers to The main purpose is to produce metallurgy and can recover coking chemical products. The coking furnace body is composed of furnace roof, combustion chamber, carbonization chamber, chute area, regenerator and other parts, and is connected by flue and chimney , the entire coking oven is built on a concrete foundation. The basic structure of modern coking ovens is roughly the same, but due to the different coal charging methods, heating methods and fuels used, they can be ...
