Vertical high-temperature environmental protecting briquette drying oven

Abstract

The invention relates to a briquette drying oven. The briquette drying oven comprises distribution ports (3) positioned at the upper part, and wind distribution plates (11) positioned below the distribution ports; and a box body (4) is defined in space between the two adjacent wind distribution plates (11). The briquette drying oven is characterized in that the box body (4) and the horizontal plane form an oblique angle of about 20-45 degrees. As the drying oven is synchronously provided with multiple distribution ports, materials are distributed more uniformly; and the box body adopts an inclined design, so that the gravity and the pressure are effectively reduced in the briquette downward moving process, the friction force is reduced, and the dust generation quantity is prominently reduced. In addition, through special structure design of wind distribution pipelines and wind distribution holes, the briquette drying strength becomes uniform and ordered. The unloading narrowing place is hoisted, so that the problem of different discharge speeds is effectively solved, and the material accumulating problem is solved. Because of solution of the dust and material accumulating problems, the firing possibility is largely reduced, and the furnace temperature design can be raised to 200 DEG C.

Description

technical field [0001] The present invention relates to a briquette drying furnace, in particular to a vertical special briquette drying furnace, and more particularly to a vertical high-temperature environment-friendly special briquette drying furnace. In addition, the present invention also relates to the use of the briquette drying furnace in briquette drying, and the briquette drying method. Background technique [0002] At present, under the background of Beijing-Tianjin-Hebei control of atmospheric smog, my country's briquette industry, especially the promotion of civil briquette is in full swing. In 2017, Hebei Province plans to promote about 8 million tons of briquette coal. With the continuous development of the briquette industry and the continuous establishment of production lines, the use of briquette drying furnaces must be an important direction to increase production. [0003] The prior art generally uses horizontal drying furnaces and vertical drying furnac...
