PURPOSE: A dyeing apparatus is provided to efficiently recover energy by heat-exchanging and discharging waste water with high temperature. CONSTITUTION: A dyeing tank(100) is connected to a heater and a cooler. A first supply path(500) is connected to the dyeing tank. A water storage tank(200) stores water. A second supply path(600) is connected to the water storage tank. A heat pump(300) changes the supply water into the coolant. A discharge flow path(700) discharges the waste water of the dyeing tank. A first branch flow path(800) and a second branch flow path(850) are branched from the second supply path via the heat pump. A waste water heat collector(400) changes the supply water to hot water by transmitting the heat of the waste water to the first supply path and the second branch path. |
