Abstract

The invention discloses an oxygen-enriched heat accumulating type combustion device. The oxygen-enriched heat accumulating type combustion device comprises a hearth, a first heat accumulating cavity and a second heat accumulating cavity, the hearth is connected with the first heat accumulating cavity through a first branch pipe and is connected with the second heat accumulating cavity through a second branch pipe, the first heat accumulating cavity and the second heat accumulating cavity are connected with a four-way valve, the four-way valve is connected with an air blower and an induced draft fan, the hearth is connected with a main gun, the first branch pipe is connected with a first auxiliary gun, and the second branch pipe is connected with a second auxiliary gun. The oxygen-enrichedheat accumulating type combustion device has the following beneficial effects that the first heat accumulating cavity and the second heat accumulating cavity are alternately used, so that the emissiontemperature of smoke is reduced, and the heat loss is reduced; and the first auxiliary gun and the second auxiliary gun are used for adjusting the concentration of fuel gas in the hearth, in the valve switching process, a valve corresponding to the first auxiliary gun or the second auxiliary gun is closed, then the concentration of the fuel gas is reduced, and the condition that the oxygen concentration is insufficient is avoided.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to an oxygen-enriched regenerative combustion device. Background technique [0002] A large proportion of similar non-ferrous metal smelting industries in my country melt non-ferrous metal materials through fuel combustion and heating. Due to the shortage of domestic energy, the price will inevitably rise. At the same time, due to the improvement of people's living standards, China is paying more and more attention to environmental pollution. Therefore, the non-ferrous metal industry needs to improve energy utilization and reduce energy consumption. , to reduce available carbon emissions, thereby reducing environmental pollution, which not only reduces costs, but also responds to the call of the country to protect the environment. Among them, regenerative combustion technology is widely used in the industry due to its high energy utilization rate. Committed to more perfect combustion...
