蜂窝式辐射管

Honeycombed radiant tube

Abstract

The utility model relates to a honeycombed radiant tube. The honeycombed radiant tube comprises a bend, an upper straight tube, a lower straight tube, heat accumulators, two burner nozzles and a combustion air tube. Two ends of the bend are connected with the upper straight tube and the lower straight tube respectively; each of the upper straight tube and the lower straight tube consists of a guide passage and an outer tube; each guide passage comprises a combustion tube and a supporting tube; each outer tube externally sleeves the corresponding guide passage and is longer than the same; each heat accumulator is fixed to one end, away from the bend, of each of the upper straight tube and the lower straight tube; the two burner nozzles include an upper burner nozzle and a lower burner nozzle; two ends of the combustion air tube are connected with the upper burner nozzle and the lower burner nozzle respectively; a reversing valve is arranged in the middle of the combustion air tube and connected with a combined air pump which comprises an air sucking pump and an air feeding pump. The honeycombed radiant tube has the advantages of balance of heat flow in the tube, uniformity of heat generated in the tube, uniformity of heat radiation outside the tube, novel structure, high heat generation efficiency and low utilization cost.
