Description

Technical Field

[0001] The utility model relates to the technical field of preheating furnaces, in particular to a waste heat utilization device for an expanded perlite preheating furnace. Background Art

[0002] Perlite is a glassy rock formed from acidic lava erupted from a volcanic eruption and rapidly cooled. It is named for its pearly fissure structure. Perlite minerals include perlite, obsidian, and pitchstone. Perlite has arc-shaped cracks formed by condensation, known as perlite structure, and has a water content of 2-6%. Perlite expands to become a lightweight, multifunctional, microporous new material with low apparent density, high temperature resistance, excellent thermal insulation, corrosion resistance, a wide operating temperature range, low moisture absorption, and is non-toxic, odorless, fireproof, and sound-absorbing. It has a wide range of uses.

[0003] An expanded perlite preheating furnace is a device specially designed for heating puffed perlite ore. Preheating evaporates moisture from the ore while increasing its temperature, creating favorable conditions for subsequent high-temperature expansion. Preheating furnaces are typically used in conjunction with expansion furnaces, cooling systems, separators, and other equipment to form a complete expanded perlite production line. However, existing preheating furnaces generate a large amount of waste heat during the perlite preheating process, which diffuses outward from the furnace's discharge port. If this waste heat is not utilized, it will not only waste energy but also cause thermal pollution to the environment. Utility Model Content
