The oil smoke waste gas discharged by the setting machine has the factors of large discharge amount, high temperature, large influence, complex components and the like, so that the heat energy of the waste gas is difficult to recycle. The organic waste gas of the heat setting machine has strong irritation and is not beneficial to the health of people; the energy consumption of a single setting machine is 60-100 million cards per hour, the heat energy consumed by fabric processing and setting accounts for 29 percent of the heat energy, the heat loss of the machine body accounts for about 10 percent, and the rest large amount of heat energy (more than 60 percent) is discharged and dissipated into the atmosphere along with waste gas. The energy recovery and resource recovery of the waste gas of the setting machine are necessary requirements for the sustainable development of the printing and dyeing industry. The traditional method for recovering heat energy of waste gas discharged by a setting machine is a gas-water heat exchange mode, high-temperature waste flue gas discharged by the setting machine is subjected to heat exchange with cooling water through a heat exchanger, and the heated cooling water is converged into a hot water tank for production needs.
