Air-cooler utilizing residual heat

Abstract

The invention relates to an air cooler utilizing afterheat, which comprises an upper tube box (1), a cylinder body (2), a heat exchange tube bundle (3) and a lower tube box (5), wherein the upper tube box (1) and the lower tube box (5) are arranged at the upper and the lower ends of the cylinder body (2), the cylinder body (2) is divided into two sections, namely, an upper cylinder body (2.1) and a lower cylinder body (2.2), the upper cylinder body (2.1) is the high temperature zone, the lower cylinder body (2.2) is the low temperature zone, an air inlet (N1) is arranged on the cylinder wall of the upper cylinder body (2.1), an air outlet (N2) is arranged on the cylinder wall of the lower cylinder body (2.2), a cooled water inlet (N6) and a cooled water outlet (N5) are arranged on the cylinder wall of the lower cylinder body (2.2) from bottom up, a 1# valve is arranged at the cooled water outlet (N5), a heating backwater inlet (N4) and a hot water / cooled water outlet (N3) are arranged on the cylinder wall from bottom up, a 3# valve is arranged at the hot water / cooled water outlet (N3), and the cooled water outlet (N5) on the cylinder wall of the lower cylinder body (2.2) is communicated with the hot water / cooled water outlet (N3) on the cylinder wall of the upper cylinder body (2.1) through a 2# valve. During the operation of the air cooler utilizing afterheat of the invention, not only the gas can be cooled, but also the heat energy can be extracted to generate hot water.

Description

technical field [0001] The invention relates to a cooler, in particular to an air cooler utilizing waste heat. Mainly used for cooling of compressed air. It belongs to the technical field of heat exchange equipment. Background technique [0002] Gas compression is widely used in metallurgy, chemical industry and other industries. The gas generates a lot of heat during the compression process. In order to achieve isothermal compression (approximately) at all levels, the compression process must exchange heat through the cooler. During the heat exchange process, this part of the heat must not only evaporate, but also consume energy; At the same time, in factory production and life, a large number of heating equipment and process links are needed. If the two can be combined to make rational use of this part of heat energy, then greater economic and social benefits will be obtained. At present, the existing air cooler is mainly composed of a cylinder body, a heat exchange tu...
