[0005] Furthermore, the cross-section of the device body is circular.

[0006] Furthermore, the air inlet is arranged above the heat exchange tube, and the air outlet is arranged below the heat exchange tube.

[0007] Furthermore, the air intake valve is arranged above the air intake port.

[0008] Furthermore, the air outlet valve is arranged in the device body.

[0009] Furthermore, an acid-resistant cement anti-corrosion layer is provided on the flower plate below the air inlet.

[0010] Furthermore, a support is provided at the bottom of the equipment body.

[0011] Beneficial effect: Compared with the prior art, the utility model has the following significant advantages: the utility model has a reasonable structure, an air inlet valve is installed on the upper part of the air inlet, and the air outlet is switched through the air outlet valve. When the equipment is running, the air outlet valve will open, and when the equipment is stopped, the air outlet valve will close. Heat is exchanged inside the equipment through the heat exchange tube, and excess high-temperature flue gas flows through the inside of the heat exchange tube to exchange heat with the water in the equipment. The heat-exchanged water goes to the production through the water outlet. The upper and lower ends of the heat exchange tube are fixed with flower plates, and a ceramic sheath tube is inserted into the upper end of the heat exchange tube to alleviate the impact of high-temperature exhaust gas on the heat exchange tube. A layer of acid-resistant glue anti-corrosion layer is made above the flower plate, which can play a corrosion-resistant effect. The utility model can more effectively avoid the waste of excess heat in the exhaust gas treatment stage, improve energy utilization efficiency, and ensure the safe operation of the equipment. The equipment is safe to operate and easy to maintain, which meets actual use needs. BRIEF DESCRIPTION OF THE DRAWINGS
