Repairing device for heat exchanger of desorption tower

The invention discloses a desorption tower heat exchanger repairing device which comprises a repairing sleeve used for being embedded in a corrosion tube nest and provided with a connecting part fixedly connected with the lower end of the corrosion tube nest; the material box is used for storing heat-conducting cement gum; the first end of the feeding pipe is communicated with the material box, and the second end of the feeding pipe extends into the repairing sleeve and is used for filling the heat-conducting cement gum in the material box into a gap between the repairing sleeve and the corrosion column pipe in the radial direction from the upper end of the repairing sleeve. According to the repair device for the heat exchanger of the desorption tower, the repair sleeve is embedded in the corrosion tube nest and fixedly connected with the lower end of the corrosion tube nest, heat conduction cement gum in the material box is injected into the radial gap between the repair sleeve and the corrosion tube nest th
