Molten iron tank waste heat utilization system

Abstract

The invention discloses a molten iron tank waste heat utilization system. The molten iron tank waste heat utilization system comprises a supporting base, a groove for fixedly installing a molten irontank is formed in the upper surface of the supporting base, a heat preservation plate surrounding the periphery of the molten iron tank is arranged on the periphery of the molten iron tank, a spiral heat exchange pipe is wound on the outer surface of the molten iron tank, the bottom periphery of the heat preservation plate is inserted into a positioning cylinder, a metal ring is arranged over theheat preservation plate, a coaxial circular plate is arranged in the metal ring, the metal ring and the circular plate are fixed through a plurality of fixing pipes arranged at equal intervals, and anintermittent air pump is fixedly installed on the upper surface of the circular plate. According to the invention, a moving module is matched with the intermittent air pump, hot air floating on the surface of the molten iron tank can be pumped away and then utilized, meanwhile, the contact area between the spiral heat exchange pipe and the molten iron tank can be increased, the heat exchange efficiency is improved, and the waste heat utilization efficiency of the molten iron tank is improved.

Description

technical field [0001] The invention relates to the field of recovery of waste heat from molten iron tanks, in particular to a waste heat utilization system of molten iron tanks. Background technique [0002] At present, after the damaged molten iron tank is transported to the maintenance workshop, due to the high temperature of the tank, the damaged part cannot be repaired immediately, and it can only be repaired after being placed in the air for a long time to cool naturally. This directly leads to the waste of waste heat resources remaining in the hot metal tank, which is not in line with the concept of energy saving and emission reduction advocated by the country. [0003] Therefore, a waste heat utilization system of molten iron tank is proposed. Contents of the invention [0004] The object of the present invention is to provide a system for utilizing waste heat from a molten iron tank to solve the problems raised in the above-mentioned background technology.
