Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment devices, in particular to a glass fiber reinforced plastic tail gas treatment device. Background Art

[0002] Tempering furnace, also known as glass tempering furnace, is an industrial heating equipment for tempering glass. It consists of four parts: placing segment, convection heating section, flat tempering section and taking segment, as well as high-pressure centrifugal fan, air supply duct, air collecting box, air circuit, electrical control cabinet, operating table, etc. The function of tempering furnace is mainly to form compressive stress on the surface of glass and tensile stress inside glass through physical or chemical methods. In this way, when the glass is subjected to external force, the compressive stress layer can offset part of the tensile stress to avoid glass breakage, thereby achieving the effect of improving the strength of glass. Glass tempering furnace is widely used in various fields that need to produce tempered glass. At present, a certain amount of exhaust gas will be generated during the operation of glass tempering furnace. If it is directly discharged into the air, it is easy to cause air pollution. Therefore, it is usually necessary to treat the exhaust gas of glass tempering furnace.

The present application, through the arrangement of the connecting pipe, the exhaust pipe and the circulating pipe, guides the exhaust gas of the glass tempering furnace into the exhaust gas treatment box through the connecting pipe for purification treatment in sequence to remove impurities and particles in the exhaust gas, and then the purified gas is discharged through the exhaust pipe, and then discharged into the connecting pipe through the circulating pipe for recycling and treatment, which further improves the filtering effect of the exhaust gas and avoids subsequent pollution of the environment; compared with the existing exhaust gas treatment device, it can circulate and filter, and improve the purification effect of the exhaust gas.
