Abstract

The invention provides a thermal energy recovery device for a spinning fabric energy-saving dryer and aims to solve the problem of low recovery rate of thermal energy in waste gas in the prior art. The thermal energy recovery device comprises a water tank, a waste gas exhaust channel, an upper fresh air inlet channel and a lower fresh air inlet channel. The upper fresh air inlet channel and the lower fresh air inlet channel are U-shaped channels with leftward openings. The waste gas exhaust channel is formed by a main channel and two branch channels, the left end of the main channel is provided with a waste gas inlet, and the left end of each branch channel is provided with a waste gas outlet. The main channel is positioned between the upper fresh air inlet channel and the lower fresh air inlet channel, and the two branch channels are positioned in the water tank. The branch channels of the waste gas exhaust channel are positioned in water and facilitate heat transfer to the water; the main channel of the waste gas exhaust channel is positioned between the upper fresh air inlet channel and the lower fresh air inlet channel, the preheating of fresh air is not performed through the water, and the thermal energy recycling efficiency is improved.

Description

technical field [0001] The invention relates to a heat energy recovery device for a textile cloth energy-saving dryer. Background technique [0002] At present, high-temperature waste gas will be generated during the use of textile dryers, and direct discharge of high-temperature waste gas will cause great waste of resources. In order to save energy and reduce costs; some enterprises think of recycling heat energy, and generally use water to reduce waste gas in the waste gas. The heat energy is recovered, and then the water after absorbing the heat energy is used to preheat the new gas to achieve the purpose of heat energy recovery. It will cause great waste. SUMMARY OF THE INVENTION [0003] The invention provides a heat energy recovery device for an energy-saving dryer for textile fabrics, aiming at solving the problem of low heat energy recovery rate in waste gas in the prior art. [0004] In order to solve the above technical problems, the present invention is achiev...
