Embodiment Construction

[0018] figure 1 Among them, the air supply pipes (5) and (6) used to make the isolation air curtain (8) are laid flat on the bottom of the inner side of the furnace pool wall brick (2), and the groove at a certain height inside the melting furnace pool wall brick Inside. The gas is ejected through one or several rows of ventilation slits or ventilation holes on the pipe wall, and a layer of isolation air curtain (8) is created between the inner surface of the furnace wall brick (2) and the melt (9), The furnace pool wall brick (2) is isolated from the melt (9) to reduce or prevent the melt (9) from contacting and eroding the furnace pool wall brick (2). In order to ensure that the above-mentioned isolation air curtain (8) is always attached to the refractory surface of the melting furnace pool wall, the upper end of the inner surface of the melting furnace pool wall can be inclined at an angle to the inner side of the kiln pool. The gas supply pipes (5) and (6) laid flat abo...

Abstract

An air curtain protection method for the bath wall of a melting furnace is characterized in that an isolation air curtain is made between the brick inner surface of the bath wall of the melting furnace and melt, and bath wall bricks of the melting furnace are isolated from melt so as to reduce or avoid the corrosion of melt to the bath wall bricks of the melting furnace due to contact. Gas used by the isolation air curtain can be compressed air, combustion smoke and the like, and the gas of the isolation air curtain is supplied by one row or multiple rows of ventilation seams or ventilation holes in the pipe walls of air supply pipes. The air supply pipes can be paved at the bottom of the brick inner side of the bath wall of the melting furnace or in certain-height grooves in the brick inner side of the bath wall of the melting furnace. The air supply pipes paved can run through the width or the length of the melting bath of the melting furnace in the length direction and extend out of the bath wall on the two sides. The air supply pipes can also be vertically closely arranged and cover the brick inner surface of the bath wall of the melting furnace. The upper ends of the air supply pipes extend out of the bath wall bricks of the melting furnace, so that the connection of an air source and the change and maintenance of the air supply pipes are convenient.

Description

technical field [0001] Furnace structure, especially glass furnace structure. Background technique [0002] The service life of the melting furnace and even the glass production line is generally determined by the service life of the melting furnace pool wall. At present, the protection of the wall of the glass melting furnace is to adopt the method of high-pressure air cooling on the outer surface of the wall brick of the melting furnace. Its disadvantages are: 1. The pool wall bricks cannot be fully insulated, resulting in heat loss; 2. A large amount of cooling air causes a large loss of energy; 3. The pool wall bricks are still severely eroded, which affects the service life of the furnace. Contents of the invention [0003] In order to solve the above problems, the present invention provides an air curtain protection method for the furnace wall, which is characterized in that: a layer of isolation air curtain is made between the inner surface of the furnace wall bric...
