Hot air pipeline of biological particle burner and manufacturing method of hot air pipeline

Abstract

TA biological particle burner is erected on a main pipeline between main heat supply equipment and heat utilization equipment, so that double-pipeline heat supply is realized. An air opening is arranged on an outer disc body to enable the main pipeline to be communicated with the outside, so that matched heat supply of double heat sources is realized. Insertion plates are inserted into insertion grooves in the two sides of the air opening, and the air inlet amount at the air opening can be adjusted. When the biological particle burner is in use, the temperature of a lining part can be reduced, the service life can be prolonged, meanwhile, the smoke temperature of the biological particle burner can be adjusted, and cracking of a spraying layer in a cold and hot transition area is avoided; and when the biological particle burner is closed, the cold air volume in the main pipeline can also be adjusted. Traditional single heat supply is changed, matched heat supply of the double heat sources is achieved, and the risk that production activities are forced to stop when heat supply equipment is damaged or fuel supply is insufficient is eradicated.

Description

technical field [0001] The invention relates to the technical field of slag micropowder production, in particular to a hot air pipeline of a biological particle burner and a manufacturing method thereof. Background technique [0002] Slag fine powder is the powder collected from granulated blast furnace slag after grinding, drying and powder selection. Slag micropowder can replace cement in an equal amount, and the cement mixed with slag micropowder is called slag cement, which is widely used in mass concrete and anti-corrosion concrete. With the increase of mass concrete structures, the society's demand for high-performance slag cement is constantly increasing, and slag cement has been applied more and more in more and more occasions due to its unique performance advantages. The reuse of industrial waste slag in the cement industry has become a new trend in the environmental protection of solid waste and belongs to the industry frontier of solid waste utilization.

AI Technical Summary

Problems solved by technology

[0003] Coal-fired furnaces are usually used for heating in the drying of slag fine powder. Coal-fired furnaces are expensive to use, have a long erection cycle, and high maintenance costs. Due to the limitation of the plant terrain, they cannot be erected at will, and coal-fired furnaces will produce a large amount of nitrogen oxides and Sulfur oxides affect the quality of the environment; the biomass pellet burner burns cleanly, is small in size, light in weight, and can be installed in the air, but there is a gap in fuel supply

The existing heating methods are all one-to-one single heating. When the heating equipment is damaged or the fuel supply is insufficient, the production activities are forced to stop
