The invention discloses a waste heat recovery ventilator. The side, close to a return air inlet, in a ventilator shell is provided with two heat exchangers in the vertical direction, a heat isolation air channel is arranged between the return air inlet face of the first heat exchanger and the return air inlet, a first isolation air channel and a second isolation air channel are arranged between the return air outlet face of the first heat exchanger and the return air inlet face of the second heat exchanger, and a third isolation air channel is arranged between the return air outlet face of the second heat exchanger and an air exhaust port. According to the waste heat recovery ventilator, the heat isolation air channel, the three isolation air channels and return air channels of the first heat exchanger and the second heat exchanger together form a sealed and isolated air exhaust channel in the ventilator shell, and explosion preventing and solvent corrosion resisting treatment and extra heat insulation treatment on the ventilator shell of the whole ventilator are avoided. The waste heat recovery ventilator can be used for performing heat recovery on waste gas of all drying boxes of a multi-color gravure printing machine or waste gas of a compound machine and supplying gas to all the drying boxes simultaneously.
Description
technical field [0001] The invention relates to a waste heat recovery machine, in particular to a waste heat recovery machine with simple structure and high efficiency. Background technique [0002] Waste heat refers to the unused heat energy generated by various heat energy conversion equipment, energy-consuming equipment, chemical reaction equipment and production processes in the production process. In textile printing and dyeing, electroplating processing, chemical and pharmaceutical, printing drying, coal slime drying and other industrial fields, there is a large amount of waste heat that needs to be recycled. If this part of energy can be fully utilized through recycling, it will greatly reduce industrial energy consumption. [0003] Waste heat can be divided into solid carrier waste heat, liquid carrier waste heat and gaseous carrier waste heat according to the form. Among them, gaseous carrier waste heat recovery technologies mainly include: heat pipe technology, h...
