Abstract

The invention discloses an energy-saving type hot blast stove inner container which comprises a spiral air guide groove, the spiral air guide groove is composed of a plurality of air guide sub-grooves connected end to end, each air guide sub-groove is a section of spirally upward arc-shaped groove, a closed-loop structure is formed by connecting the head end and the tail end of the air guide sub-groove in an overlook mode, and the air guide sub-grooves are the same in specification. A first air inlet tangent to the spiral air guide groove is formed in the lower portion of the spiral air guide groove, the first air inlet is used for introducing air needed by combustion, the introduced air spirally ascends close to the inner wall of the spiral air guide groove, and a first waste gas outlet tangent to the spiral air guide groove is formed in the upper portion of the spiral air guide groove; a cold air inlet tangent to the spiral air guide groove is formed in the lower portion of the outer portion of the spiral air guide groove, the cold air inlet is used for introducing unheated air, the unheated air spirally ascends close to the outer wall of the spiral air guide groove, and a hot air outlet tangent to the spiral air guide groove is formed in the upper portion of the outer portion of the spiral air guide groove. The heat utilization rate of the hot blast stove is improved.

Description

technical field [0001] The invention relates to the field of hot blast stoves, in particular to an energy-saving hot blast stove liner. Background technique [0002] As a common heating equipment in industry, hot blast stove is widely used in various fields, such as smelting, firing, drying and so on. The hot blast stove can heat the cold air or normal temperature air by burning fuel, and produce hot air at the required temperature to heat the material. [0003] The inner tank of the hot blast stove, also known as the furnace tank, is often used as the combustion chamber of the hot blast stove. As a combustion chamber, the furnace requires high heat absorption efficiency and high heat transfer efficiency, so as to ensure high heat utilization rate. Due to structural limitations, the existing liner has low heat absorption efficiency, poor heat transfer efficiency, low heat utilization rate, and a lot of energy wasted. Contents of the invention [0004] In view of the abo...
