Exhaust hot air drying system

Abstract

The invention provides an exhaust hot air drying system. The exhaust hot air drying system comprises an exhaust manifold, an exhaust fan and at least two first drying units, wherein the exhaust fan is arranged at the tail end of the exhaust manifold; the first drying units comprise first unit air supply fans and first drying boxes, and are provided with first unit exhaust holes; the first drying boxes are provided with first drying box air inlets, first drying box air outlets, first drying box feed inlets and first drying box discharge holes; the first drying units are sequentially connected on the exhaust manifold through the first unit exhaust holes; air outlets of the first unit air supply fans are connected with the first drying box air inlets; the air outlets of the first unit air supply fans are connected with the first unit exhaust holes; and the first drying box air outlets are connected with air inlets of the first unit air supply fans. The exhaust hot air drying system can radically achieve the purpose of energy conservation and emission reduction, and has the advantages that the system is concise and stable, the adjustment is simple, the exhaust volume is small, the energy consumption is low, the potential safety hazard is avoided, the environmental protection treatment cost is low, and the like.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and relates to a multi-unit hot air drying process in industries such as packaging and printing, coating and coating, and is specifically applied to production equipment requiring hot air drying such as gravure printing machines, compound machines, coating machines, and furniture spray paints. . Background technique [0002] The drying system is the main energy consumption unit of printing, compounding, coating, spraying and painting production equipment, and it is also the main emission source of exhaust gas. The efficiency of the drying system is the core parameter of the production equipment performance evaluation index. [0003] At present, the drying system of most production equipment does not have a good automatic control function. During operation, the operator relies on the operator to manually adjust the operating state of the drying system based on practica...
