Problems solved by technology
However, the increase in the length and structure of the radiant tube will bring about problems in strength, rigidity, and manufacturing and installation, which will affect the service life of the radiant tube and lead to the low thermal efficiency of the existing mesh belt furnace.
[0004] At the same time, due to the uneven distribution of gas combustion temperature in the gas radiant tube, it will also cause low thermal efficiency and high emissions of NOx and CO in the exhaust gas, causing pollution to the atmosphere

The invention provides a mesh belt furnace and porous media gas burners. The mesh belt furnace comprises a quenching furnace and / or tempering furnace, wherein the quenching furnace comprises a first hearth body; the first hearth body comprises a first preheating area, a first heating area, a heat preservation area and a quenching pool which are sequentially arranged; the tempering furnace comprises a second hearth body; the second hearth body comprises a second preheating area, a second heating area and a cooling area which are sequentially arranged; and the porous media gas burners are arranged at the top and / or side of the first heating area and the top and / or side of the second heating area. In the coexistence of the quenching furnace and the tempering furnace, a mesh belt drive systemcan be further included, so that the quenching furnace and the tempering furnace are connected through a mesh belt of the mesh belt drive system. The mesh belt furnace in the invention has the characteristics of sufficient combustion, uniform temperature field, no temperature high point and low emission of CO and NOx. The thermal efficiency can be improved by the improved structures of the porousmedia gas burners.
Description
technical field [0001] The present application relates to the technical field of heat treatment technology, in particular to a mesh belt furnace and a porous medium gas burner. Background technique [0002] Mesh belt furnace is a sintering furnace that continuously conveys objects through a mesh conveyor belt and performs multi-stage processing on materials during the conveying process. It is mainly used for sintering of powder metallurgy products and reduction of metal powder and electronic products. Pre-firing, firing or heat treatment process in protective atmosphere or air. At present, the mesh belt heating furnace is quite common in the heat treatment industry. The heating of the existing mesh belt furnace generally relies on a single electric radiant tube or gas radiant tube for heating. [0003] The thermal efficiency of gas radiant tubes is about twice that of electric heating radiant tubes. Therefore, gas radiant tubes are usually preferred in current mesh belt fu...
