Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cooling of glass furnaces, in particular, to a cooling air system of a glass furnace and a glass furnace. BACKGROUND

[0002] The melting part of a photovoltaic glass furnace needs a cooling air system for cooling to ensure that the brick and steel structure of important parts of the melting part can operate. Generally, the cooling air system of the furnace mainly includes a pool wall cooling air system, a crown cooling air system, an L-hanging wall (front wall) cooling air system, a lance cooling air system, a bubbler cooling air system, etc.

[0003] According to the principle of proximity, the cooling air system of the lance is usually taken from the pool wall cooling air system to simplify and shorten the pipeline laying. However, the pool wall cooling air system is usually opened after the liquid glass is in place at the end of the furnace baking, while the lance cooling air system needs to be used after the furnace is baked with high fire, which leads to the fact that the lance cooling air system cannot meet the requirements of the process flow when taking air from the pool wall cooling air system. If a fan is added separately for the lance cooling air system, the equipment failure rate and operating cost will increase. CONTENT OF THE UTILITY MODEL
