Abrégé

An air amplifier having the function of amplifying an air flow comprises an inner sleeve (1) and an outer sleeve (2). The inner sleeve is integrally formed of a first body (11) and a second body (12). The section where a first through hole (112) is located inside the first body is an air exhaust port (f). The outer sleeve is integrally formed of a third body (21) and a fourth body (22). The section where a second through hole (23) is inside the fourth body is horn-shaped, and the horn-shaped section is an air discharge port (e). The second body is inserted inside the second through hole. A groove (13) is annually provided in the circumferential direction of the second body. An annular cavity (b) is annually disposed in the circumferential direction of the section where the second through hole is inside the fourth body. The groove and the annular cavity are correspondingly arranged to jointly form a chamber. The third body is provided with a compressed air inlet (a), and the compressed air inlet communicates with the annular cavity. A chamfer (121) is disposed at the end portion of the second body. A plurality of seams (c) is disposed on the chamfer. A conical surface (231) is disposed at the position inside the second through hole that is in contact with the chamfer. The connection between the conical surface and the smaller caliber end of the horn-shaped section of the second through hole is convex in the axial direction of the second through hole. The air amplifier is applicable to the field of glass deep processing and helps the production of off-line coated glass.

An inlet and outlet wind heat exchange system for a radiation-type heating furnace comprises one enclosed heat exchange box (5), the heat exchange box is provided with a hot air inlet (51) and a hot air outlet (52), the hot air inlet (51) communicates with the hearth of the radiation-type heating furnace, and the hot air outlet (52) communicates with a wind inlet of one centrifugal fan (4). A plurality of heat exchange tubes (6) is further disposed inside the heat exchange box (5), one end of the heat exchange tube (6) communicates with a cold air source, and the other end communicates with the hearth of the radiation-type heating furnace. As the air is heated by the residual heat discharged by a furnace cavity and then enters the furnace cavity, energy consumption required for temperature rise can be reduced; meanwhile, the centrifugal fan bleeds the hearth of the high-temperature gas, so that the gas pressure inside and outside the furnace is balanced, which enhances the production safety.
