Detailed Description
The following describes the waste heat recovery device of heat treatment equipment in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the waste heat recovery device for waste gas of heat treatment equipment comprises an inner sleeve 1, an outer sleeve 2 coaxially sleeved on the inner sleeve 1, and a heat exchange tube 6 coaxially arranged in the inner sleeve 1. The inner sleeve 1 is internally provided with a first cavity, and the upper end and the lower end of the first cavity are communicated with the outside. A second cavity is formed between the inner sleeve 1 and the outer sleeve 2, and the upper end and the lower end of the second cavity are both closed. The upper part of the outer sleeve 2 is provided with a combustion-supporting air outlet 3 communicated with the second cavity, and the lower part of the outer sleeve 2 is provided with a combustion-supporting air inlet 4 communicated with the second cavity. The upper end of the heat exchange tube 6 is bent to the middle upper part of the second cavity, and the lower end of the heat exchange tube 6 is bent to the middle lower part of the second cavity.
In this embodiment, the upper end of the heat exchange tube 6 is bent to a position corresponding to the combustion air outlet 3, and the lower end of the heat exchange tube 6 is bent to a position corresponding to the combustion air inlet 4. A plurality of first fins 5 are uniformly arranged on the outer side of the inner sleeve 1 along the circumferential direction. A plurality of second fins 7 are uniformly arranged on the outer side of the heat exchange tube 6 along the circumferential direction. And each fin is fixed on the corresponding pipe wall in a welding mode.
The utility model discloses a heat treatment equipment waste gas waste heat recovery device's theory of operation does:
when the heat treatment equipment normally operates, hot waste gas in the furnace enters the inner sleeve 1, the combustion-supporting fan blows cold combustion-supporting air into the second cavity from the combustion-supporting air inlet 4 and exchanges heat with the hot waste gas in the inner sleeve 1, wherein part of the combustion-supporting air exchanges heat in the second cavity through the pipe wall of the inner sleeve 1 and the first fins 5, and part of the combustion-supporting air enters the heat exchange pipe 6 and exchanges heat with the hot waste gas in the inner sleeve 1 through the pipe wall of the heat exchange pipe 6 and the second fins 7.
