Abstract

The invention discloses a method for eliminating positive pressure of a baking furnace of a color coating unit. The method comprises the steps that a smoke discharge pipeline is additionally mounted on an outlet of the baking furnace; automatic gate board devices are arranged on an inlet and the outlet of the baking furnace; the exhaust capacity of a waste discharge fan behind a main exhaust fan and a heat exchanger is improved; and the air supply quantity and the exhaust quantity of the baking furnace are set. Through the above technical scheme, the problem about positive pressure of air in the color coating baking furnace can be effectively solved, and therefore the process and quality stability of production of the color coating unit is improved, and production safety is guaranteed.

Description

technical field [0001] The invention relates to a method for eliminating the positive pressure of a baking furnace of a color coating unit, and belongs to the technical field of steel color coating. Background technique [0002] As a new type of material that is environmentally friendly, energy-saving and easy to process and shape, color-coated board has been widely used in construction, home appliances, decoration and other fields. With the continuous improvement of customers' requirements for the use and quality of color-coated products, the application of products is becoming more and more extensive. Light-steel buildings, house structures, high-rise curtain walls, etc. have begun to use color-coated products directly on a large scale. Since this product can be formed at one time, it has brought Color coating does not require chemical anti-corrosion treatment, spraying and other processes, and can completely discharge VOC exhaust gas and heavy metal-containing wastewater ...
