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.

The present invention compares with prior art has following technique effect:

1, the heat setting machine exhaust heat air purification heat energy utilizes the heat exchange heat pipe (11) of heat exchange of heat pipe, tube sheet (10) top is spiral fin coil, tube sheet (10) bottom is the structure of longitudinal finned tube, the used heat air is by longitudinal fin heat pipe absorbing and cooling temperature, oil vapour is condensed into liquid on longitudinal fin, trickle to bottom drawer type oil trap by self gravitation, avoided helical fin plug cock scene, heat exchange of heat pipe (1) hotair chamber top cover can be opened simultaneously, be assembled in detachable cleaning of heat pipe (11) on the tube sheet (10), heat recovery reaches 40-50% when guaranteeing heat exchange of heat pipe (1) long-time running.

2, in used heat air and air air intake adapter (7), there be convenient the installation to change slot (5) removing used heat air and the airborne yarn dirt of heating that removes yarn dirt, avoid the yarn dirt of heat exchange of heat pipe (1) heat-exchange surface to stop up a difficult problem, arranging temperature sensor adapter (9) in four outlet and inlets adapters up and down simultaneously, synthermal display instrument (9) connects, and shows operating condition.

3, heat pipe (11) the absorbing and cooling temperature condensation through heat exchange of heat pipe (1) splits out big portion oil vapour, go up at used heat hot-air heat-absorbing chamber discharge connection (7) again electrostatic pulse cooking fume remover (2) is installed, the low temperature off-air that contains oil gas forms high voltage electric field through high-voltage pulse power source between positive/negative plate, oil gas ionization is adsorbed on the cathode electrode, fall back in the bottom oil sump tank (20) by self gravitation, reach the requirement of basic Ex-all oil gas.Guarantee that heat setting machine used heat air yarn dirt exhaust of oil meets national requirements for environmental protection.
