Xuan paper drying and baking flue gas treatment system

Abstract

The invention discloses a rice paper drying and baking part flue gas treatment system. The rice paper drying and baking part flue gas treatment system comprises a rice paper drying and baking part of a box type structure, wherein a wall body of the rice paper drying and baking part comprises baking walls which are opposite to each other and have inclined wall surfaces; the outer wall surfaces of the baking walls are of opposite inclined surface shapes; two ends of the two baking walls are provided with gable walls; the baking walls and the gable walls surround to form a chamber; the lower part at one end of the chamber is provided with a heating flue gas inlet; the heating flue gas bypasses the chamber, then is guided out from the chamber, is output into a scrubbing tank for absorbing dust and filtering flue gas, and then is emitted to the outside. When in use, the heating flue gas enters the chamber of the rice drying and baking part from the flue gas inlet, so that the heating flue gas in the flowing process is naturally used for heating the baking walls of the rice paper drying and baking part to certain temperature, and then the paper baking technology is carried out; in addition, the heating flue gas bypasses the chamber, then is guided out from the chamber finally, and is conveyed into the scrubbing tank, so that impurities in the flue gas can be scrubbed, and the roles of cleaning dust and filtering flue gas are played; the finally filtered gas is directly emitted to atmosphere externally. The rice paper drying and baking part flue gas treatment system is simple in structure and is high in use cleanliness.

Description

technical field [0001] The invention relates to the field of rice paper processing, in particular to a rice paper drying and roasting flue gas treatment system. Background technique [0002] Rice paper is a traditional handicraft, and its production process includes cooking, beating, fishing, paper drying, paper cutting and other processes. Drying or drying. At present, the heating methods of rice paper drying and baking mainly include introducing steam into the inside of the sealed rice paper drying and baking, or using coal combustion for heating. When coal combustion is used for heating, the coal raw materials are mostly placed in the rice paper drying and baking. Combustion is carried out on one side, and the heat generated by coal combustion is guided into the rice paper drying and baking through the pipeline to heat the baking paper surface of the rice paper drying and baking, thereby drying the rice paper attached to the baking paper surface. During the process, when...

Problems solved by technology

However, it has been found in actual work that during the process of starting the furnace, adding coal to the coal furnace, or prying ash to remove cinders, there will be a large amount of fine particles in the flue gas generated in the rice paper drying and roasting, and these fine particles will be accompanied by the flue gas. Exhausted into the atmosphere, not only the air pollution is serious, but these particles will also be deposited in the rice paper production area in the long run, which also greatly increases the work intensity of the cleaning staff. Therefore, how to ensure the air quality of the paper drying environment and reduce environmental pollution, This is a question that companies must consider
