Abstract

The invention relates to a waste heat recovery device for a natural gas continuous stepping curing oven, which comprises a smoke guide pipe. The smoke guide pipe is connected into a smoke discharge pipe of the natural gas continuous stepping curing oven, a heat exchange pipe is sleeved outside the smoke guide pipe, two ends of the heat exchange pipe are hermetically connected with two ends of the smoke guide pipe, an air cavity is formed between the heat exchange pipe and the smoke guide pipe, the smoke guide pipe is sequentially provided with a cool air inlet and a hot air outlet along the smoke direction, and the cool air inlet is connected with a cool air fan. The waste heat recovery device is applicable to the natural gas continuous stepping curing oven, and can effectively use heat in high-temperature smoke generated after combustion of a combustor.

Description

technical field [0001] The invention relates to a waste heat recovery device of a natural gas continuous walking solidification furnace. Background technique [0002] Such as Figure 4 As shown, the structure of the currently used natural gas continuous step-by-step curing furnace includes a curing furnace body 8, on which a burner 9 for heating is arranged, and the high-temperature flue gas produced by the combustion of the burner 9 passes through the exhaust gas. The chimney 2 leads to a chimney 10 for discharge. Because the high-temperature flue gas produced after the combustion of the burner 9 has a lot of heat energy, it is directly discharged through the chimney 10 and causes a lot of energy waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a waste heat recovery device for natural gas continuous walking solidification furnace that can effectively utilize the heat energy in the high-temperature flue ga...
