Abstract
The utility model relates to the technical field of tunnel kilns and discloses a fire stopping wall device in a medium-high-temperature tunnel kiln. The fire stopping wall device comprises a cooling region and a firing region. A transition region is arranged between the cooling region and the firing region and used for preventing convection between cool air in the cooling region and hot gas in the firing region. The furnace top of the transition region is of a flat top structure. The furnace top of the cooling region and the furnace top of the firing region are both of a circular arch crown structure. The height of the furnace top of the transition region is smaller than that of the furnace top of the cooling region and that of the height of the furnace top of the firing region. According to the fire stopping wall device, the transition region is arranged between the cooling region and the firing region, the height of the furnace top of the transition region is reduced, and the furnace top of the transition region is the flat top so that the contact between part of hot gas in the firing region and part of cool air in the cooling region can be well blocked. Consequently, the contact area of heat exchange is reduced, energy consumption is saved, the pressure of the cool air and the pressure of the hot gas are controlled easily and the convection is prevented.
