In fig. 2 the solid arrows are the smoke flow squares and the dashed arrows are the air flow directions. The flue gas flows along the directions a1, a2, a3 and a4, enters from the upper part of the flue gas channel, flows through the outer part of the multi-layer high-temperature-stage heat exchange tube bundle and the outer part of the multi-layer low-temperature-stage heat exchange tube bundle, and flows out from the lower part of the flue gas channel. Air flows along the directions of b1, b2, b3, b4, b5, b6 and b7, enters from the preheated air inlet, passes through the interior of the multi-layer high-temperature stage heat exchange tube bundle, the interior of the multi-layer low-temperature stage heat exchange tube bundle, the left air guide hoods and the right air guide hoods, and flows out from the preheated air outlet. According to the heat exchanger structure, on one hand, the heat exchanger is in a layered arrangement form by adopting the heat exchange tube bundles, so that the occupied area of the heat exchanger can be effectively reduced, the field operation environment of workers is improved, and the heat exchange efficiency can be improved, so that a better heat exchange effect is obtained, and meanwhile, an orthogonal countercurrent heat exchange mode is adopted, so that the heat exchange effect is favorably improved; on the other hand, the heat exchange form of two-stage series connection of the high-temperature-stage heat exchange tube bundle and the low-temperature-stage heat exchange tube bundle is adopted, the high-temperature-stage heat exchange tube bundle is arranged on the inlet side of the flue gas channel, the high-temperature-stage heat exchange tube bundle can be prevented from being damaged due to overhigh temperature, the problems of air leakage and air leakage are solved, the low-temperature-stage heat exchange tube bundle is arranged on the outlet side close to the flue gas channel, the heat exchange requirement is met, and meanwhile the material cost is reduced. In a word, the heat exchanger structure of this application compares in the resistant firebrick and the hollow cylindrical brick structure of commonly used, can effectively avoid air flue gas to crowd gas, leak out, slagging scorification scheduling problem, helps preheating air mass flow's meticulous control to promote the natural gas combustion efficiency in the zinc rectifying furnace.
The high-temperature-level heat exchange tube bundle comprises a plurality of high-temperature-level heat exchange tubes 201 arranged in an array, and the low-temperature-level heat exchange tube bundle comprises a plurality of low-temperature-level heat exchange tubes 202 arranged in an array. After entering the flue gas channel, the flue gas flows through gaps between the high-temperature-level heat exchange tubes and the low-temperature-level heat exchange tubes, and the air and the flue gas exchange heat fully.
