Exhaust heat recovery device for bio-oil hydrogenation reaction

Abstract

The utility model relates to biological oil hydrogenation reaction's waste gas waste heat recovery device, including heat exchange box and the even distribution fixed in the multiple heat exchange pipes of heat exchange box, is equipped with the air inlet pipe and exhaust pipe on the front and back side wall of heat exchange box respectively, the left and right side wall of heat exchange box all fixedly connect with sealed end cap, and the sealed end cap and heat exchange box form sealed cavity between, the left and right ends of heat exchange pipe are communicated with two sealed cavities respectively, and two sealed end caps are equipped with water inlet pipe and water outlet pipe respectively, the waste gas purifier is connected to the smoke inlet pipe, and the waste gas purifier has neutralization filter layer. The utility model first enters waste gas purification box when waste gas input, and the acidic gas in waste gas is neutralized through neutralization filter layer, then enters heat exchange box and heat exchange pipe through air inlet and carries out heat exchange, to greatly reduce the corrosion of acidic medium to heat exchange pipe, increase the service life of heat exchange pipe.
