Description

A kind of Industrial Stoves

Technical field

This utility model kiln technical field, specifically, is a kind of Industrial Stoves, using tunnel cave design.

Background technology

Kiln is the equipment in order to burnt product being built into refractory material, is the indispensable facility in pottery art molding.The mankind The pottery of up to ten thousand years burns makes history, have accumulated and abundant makes kiln pattern and experience.From the ground of primitive society outdoor burnt in a heap, dig pit Build and burn steamed bread shape liter flame circular kiln, half downdraf horse shoe flame furnace, half way up the mountain dragon kiln, oval kiln, then to Indoor Air kiln now, electricity Kiln, kiln science and technology is in continuous improvement.

Tunnel cave is the Thermal Equipment that the continuous way modernizing is burnt till, and is widely used in the baked for producing of ceramic product, in mill Also there is application in the metallurgy industries such as material.Tunnel cave is usually a long linear tunnel, and fixing wall is arranged at its both sides and top Wall and vault, the track of bottom laying runs kiln car.Combustion apparatus is located at the middle part both sides of tunnel cave, constitutes fixing Thermal zone clinkering zone, burns the high-temperature flue gas producing in the presence of tunnel cave front end chimney or air-introduced machine, along tunnel to kiln The flowing of head direction, preheating enters the product in kiln step by step simultaneously, and this section constitutes the preheating zone of tunnel cave.In tunnel cave Kiln tail blasts cold wind, latter one section of product in cooling tunnel kiln, after the cold wind blasting flows through product and is heated, then extracts feeding out As the thermal source that green compact are dried, this section just constitutes the cooling zone of tunnel cave to exsiccator.

Because tunnel cave is seriality kiln, heat utilization preferably, and the combustion air that uses of most tunnel cave take be Natural wind or be blown into cold wind in cooling zone, so that air heating.Although UTILIZATION OF VESIDUAL HEAT IN, because in the hot-air extracted out, mix Enter to have very how thermal zone burned waste gas, so leading to oxygen deficiency in combustion air, combustion efficiency is not good.Using heat exchange The hot-air that device swaps out is fresh hot-air, can reach optimal combustion-supporting effect.If using metallic recuperator, Ke Yijin The waste heat recovery of a row part, but if cooling zone temperature reaches more than 800 degree, metallic recuperator is very easy to be damaged by high temperature Bad.
