Waste rubber high temperature plasticized lampblack incineration purification device and method

Abstract

The invention belongs to the technical field of exhaust gas treatment, and discloses a waste rubber high temperature plasticized lampblack incineration purification device and method. The device comprises a filter, a Venturi injector, a heating mixer, an incinerator and a tubular heat exchanger. A discharge hole of the filter is connected to a feed inlet of the Venturi injector, and the heating mixer comprises a mixing cavity and an inner tube arranged in the mixing cavity in a sleeved mode. A discharge hole of the Venturi injector is connected to an inlet of the mixing cavity, and an outlet of the mixing cavity is connected to a feed inlet of the incinerator. A discharge hole of the incinerator is connected to an inlet of the inner tube, and an outlet of the inner tube is connected to anin-tube chamber of the tubular heat exchanger. An outlet of the in-tube chamber of the tubular heat exchanger is connected with an induced draft fan, an air inlet is formed in one end of an out-of-tube chamber of the tubular heat exchanger, and an air outlet is formed in the other end of the out-of-tube chamber of the tubular heat exchanger. The air outlet is connected to the inlet of the mixing cavity. The device directly incinerates lampblack without condensation, and the lampblack is fully burned to avoid secondary pollution of condensed fluid.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste rubber high-temperature plasticized oil fume incineration purification device and method. Background technique [0002] During the heating and plasticizing process of waste rubber, the material needs to be heated to above 200 degrees. At this temperature, the low-boiling point organic matter and water in the material will evaporate, and the material will also produce part of the cracked product, which will form oily smoke. The environment is seriously polluted. The commonly used method is to condense first, and then incinerate the non-condensable steam. Condensate will be produced during condensation. When the condensate is of little value for recycling, it will cause secondary pollution to the environment and increase the difficulty of treatment. Contents of the invention [0003] In view of the above situation, the object of the present invent...
