Heat shaped machine exhaust heat air purification heat energy utilized heat pipe exchanger

Abstract

A heat pipe heat exchanger for waste heat air purifying and heat energy utilization of heat setting equipment is a heat pipe heat exchanger that is provided with heat pipes of different working mediums. An exothermic section of an air side heat pipe is of a spiral fin structure, and an endothermic section of a waste heat air side heat pipe is of a longitudinal fin structure. 50 percent of heat energy is recycled when the temperature of the waste heat air falls from 180 DEG C to 70-80 DEG C. At the same time, a waste heat air inlet tube and a heated air inlet tube are provided with a slot with a detachable and replaceable yarn dust filtering netting; the steamed and liquidized air that is condensed and discharged from the waste heat air with the heat absorbed by the heat pipe of longitudinal fin structure flows into an oil sump tank along the longitudinal fin, enters a low temperature electrostatic pulse oil fume staticizer, and the oil molecular is ionized in the high pressure pulse positive-negative electrode electric field. The waste heat air discharged from the heat setting equipment fundamentally reaches the requirements of environment protective of low temperature, dust free and oil free.

Description

technical background [0001] The invention belongs to a heat pipe device for purifying high-temperature exhaust gas, dust oil and recycling heat energy of heat setting machines in the textile printing and dyeing industry. Background technique [0002] In the textile printing and dyeing industry, the heat setting machine is a large energy consumer; the temperature of the hot air used by the heat setting machine is 200-230°C, and the temperature of the waste heat exhausted after the finished fabric is consumed is 180-200°C, and contains a relatively high concentration of yarn dust And heat setting machine running lubricating oil steam, high-temperature waste heat air containing dust and oil is directly discharged into the atmosphere, wasting 90% of low-grade heat energy and polluting the environment; currently, the devices for recovering heat setting machine waste heat air include rotary type, tube type and Plate heat exchangers, but there are generally disadvantages such as lo...
