Embodiment Construction
[0020] As shown in Fig. 1, Fig. 2 and Fig. 3, embodiment 1 of the ventilating plate of the present invention and the wear-resistant hood having the ventilating plate, the circular ventilating plate 1 is welded with the conical air duct 2, and the air duct 2 is connected with the air duct 3 welded together. The flat-plate ventilation plate 1 is provided with oblique ventilation holes 4, and the inclination angle range between each ventilation hole 4 and the plane perpendicular to the axis of the air cylinder 2 is 3° to 90°, and the inclination angles of each ventilation hole 4 are different, The orientation of the oblique direction of the ventilation holes 4 is also different.
[0021] As shown in Figure 4, the embodiment 2 of the ventilating plate of the present invention and the wear-resistant hood with the ventilating plate differs from the embodiment 1 in that the inclination angles of the ventilating holes 4 are different, (in the vicinity of the center of the ventilating ...

The invention discloses a draught penetration plate and an anti-wear wind cap provided with the same, wherein, the draught penetration plate is positioned on the top of the wind cap, the draught penetration plate is provided with more than two ventilation holes throughout the draught penetration plate, each ventilation hole is inclined to the plane vertical to the axes of a wind-cone, orientations of inclined angles and inclined directions of the ventilation holes have the following relations that: the inclination angle of each ventilation hole is identical and the inclined directions of at least two ventilation holes are different, or the inclined directions of each ventilation hole are the same and the inclined angles of at least two ventilation holes are different, or the inclined directions of at least two ventilation holes are different and the inclined angles of at least two ventilation holes are different, the inclination range between the ventilation holes and the plane vertical to the axes of the wind-cone is between 3 degrees and 90 degrees. The draught penetration plate and the anti-wear wind cap solve the problems that the ventilation holes of the prior draught penetration plate are difficult to calculate and process, ensure that products are more various and have stronger competency.
Description
technical field [0001] The invention relates to an important component applied to combustion equipment in a circulating fluidized bed boiler, in particular to a ventilation plate and an anti-wear wind cap with the ventilation plate. Background technique [0002] In the circulating fluidized bed boiler, the air cap is an important component of the combustion equipment. The air cap used in a fluidized bed boiler produced by Harbin Boiler Factory is welded by the ventilation plate, the air duct and the air pipe group. The applicant of the present invention discloses an anti-wear hood in the Chinese invention patent No. 01133628.5, in which inclined air holes are evenly arranged on the air vent plate of the air cap, and the inclination directions and inclination angles of the air holes must be the same; The hood solves the problem that the air flow of the original hood scours the hood. However, in actual production, it is found that the calculation of setting the ventilation ho...
