業効率が低下するという問題がある。However, in conventional air-cooled heat exchangers, depending on the cooling temperature, if gasified molecules in the gas or dust in the gas adhere to the inner peripheral surface of the tube, the operation is not stopped and the dust is not removed. This poses a problem in that gas pressure loss occurs and the equipment in which the heat exchanger is used shuts down. Additionally, there is a problem in that work efficiency decreases when the operation is stopped to remove dust.

触する。By the way, when the gas passes through the tube 16, dust contained in the gas adheres to the inner surface of the tube 16. In this case, when the rod 24A of the grit 24 is hammered with the hammering member 22, the grit 24 moves downward and compresses the springs 26, 26, . compressed spring 26
．． 26... expands, and then repeats the expansion and contraction. Therefore,
Grit 24 vibrates. When the grit 24 vibrates,
A buckling mode is induced in the wires 28, 28, . . . , and the wires 28 and the inner peripheral surface of the tube 16 come into contact as shown in FIG.
この結果、チューブ１６内に付着したダストは除去され
る。除去されたダストは、第１図に示すホンバ２０を経
てダスト排出口２ＯＡから排出され第 １ 図
る。As a result, dust adhering to the inside of the tube 16 is removed. The removed dust is discharged from the dust outlet 2OA via the hub 20 shown in FIG. 1.
以上説明したように、本発明に係る空気冷却式熱交換器
によれば、チューブの内周面にダスト等が付着しても、
ダスト等を除去することが出来るので、ガスの圧力損失
を防止することが出来る。As explained above, according to the air-cooled heat exchanger according to the present invention, even if dust etc. adheres to the inner peripheral surface of the tube,
Since dust and the like can be removed, gas pressure loss can be prevented.
更に、チューブを清掃するために、熱交換器の運転を停
止する必要がなく作業効率の向上を図ることが出来る。Furthermore, there is no need to stop the operation of the heat exchanger in order to clean the tubes, and work efficiency can be improved.
