Shell and Tube Finned Heat Exchanger Application (Automotive Painting VOCs Exhaust Gas)

Shell and Tube Finned Heat Exchanger Application (Automotive Painting VOCs Exhaust Gas)

Automotive painting VOCs exhaust is the production of a large number of volatile organic emissions, in the process of painting the car will use a lot of chemical products, metal and non-metallic surfaces covered with protective or decorative, which will produce a large number of chemical emissions. These chemical emissions must be treated before discharge, if directly discharged will not only cause environmental pollution will also bring harm to people's health.

   In the treatment of organic waste gas VOCs, large air volume, low concentration of volatile organic waste gas VOCs under the action of the induced draft fan through the high-efficiency filter, and then into the honeycomb activated carbon adsorption module to be adsorbed, concentrated, clean air purified by activated carbon adsorption through the chimney into the atmosphere. With the extension of time, the activated carbon adsorption capacity is close to saturation, the electronic control system controls the catalytic oxidation furnace to start heating, and at the same time preheating the precious metal catalyst, the heated high-temperature gas through the heat exchanger cooled down to 100-120 ℃ on the adsorption of the saturated activated carbon module for the heating of the adsorption desorption, desorption of the high-concentration organic waste gas through the heat exchanger preheating into the catalytic oxidation furnace for decomposition. After desorption, the high concentration of organic waste gas enters the catalytic oxidising furnace for decomposition after preheating by heat exchanger. In the catalytic oxidation furnace is heated to 250-300 ℃ organic waste gas in the precious metal catalyst under the action of flameless combustion, organic waste gas is oxidised and decomposed into CO2 and H2O, to achieve the purpose of purification.

   Shell and tube finned heat exchanger in order to facilitate the cleaning and maintenance of the actual working conditions, the gas goes to the tube course, the circulating water goes to the shell course, finned tube material corrosion-resistant stainless steel, safe, efficient and stable operation.
