Blast device for blast coal furnace

Abstract

The invention discloses a blast device for a blast coal furnace, which comprises a three-stage blast hose, a second-stage blast hose, a central support rod, a bottom support frame, a self-locking first-stage ventilation cavity, and a wind wing type strong Blower, the wind wing type powerful blower is airtightly installed on the right side of the self-locking primary ventilation cavity through hexagonal bolts, and the right side of the self-locking primary ventilation cavity is provided with a primary blast pipe, and the center support The rod is installed in the middle of the primary blast pipe, and the outer wall of the central support rod is provided with a spiral blast guide plate, and the top of the primary blast pipe is provided with a third-stage ventilation cavity and a secondary ventilation cavity , the bottom support frame is arranged at the bottom of the primary blast pipe. The self-locking primary ventilation cavity, secondary ventilation cavity and tertiary ventilation cavity of the present invention cooperate with each other, so that coal can obtain sufficient oxygen in each combustion stage and different combustion positions, burn more fully, save resources, and reduce harmful gases emission and reduce environmental pollution.

Description

technical field [0001] The invention relates to the technical field of blast coal furnaces, in particular to a blast device for blast coal furnaces. Background technique [0002] In the early days of liberation, the simplest coal stove was made of bricks, square and columnar, with a chimney connected to blow the smoke to the outside. The iron coal stove was more commonly used, cylindrical or gourd-shaped, consisting of a furnace bottom and a furnace body. It consists of two parts. The furnace body is hollow and used for charging coal. There is a damper in the front and a flue connecting the chimney in the back. Coal stoves are classified according to the use of coal and its products: ordinary coal stoves, coal pellet stoves, coal cake stoves and honeycomb coal stoves. Ordinary coal furnaces directly use coal as fuel, and coal pellet furnaces burn coal balls made of coal powder. Coal cakes are made of coal and have small holes on them. Instead, the little door in the front ...

Problems solved by technology

[0003] However, the design of the traditional coal stove is unreasonable, the effect of getting angry is not good, and the heat dissipation is serious. Because of the serious problem of ventilation, when the coal is burned, the combustion degree is low and harmful gases are produced, such as carbon monoxide. If there is too much carbon monoxide in the room, it will cause suffocation and death of people or animals. Need to find an effective blowing way to solve this serious problem
