Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0018] like Figure 2 to Figure 5 shown (for ease of illustration, figure 1 Soot collection rings, inclined plates, inserts, and dust baffles are not shown; Figure 4 The dotted line in the middle indicates the state schematic diagram when the swash plate is retracted, Figure 4 Dust baffle is not shown), the present invention is a chimney top anti-soot structure, including the chimney rear wall 1 inclined to the horizontal plane; The lower end of 1 is provided with a sloping plate 3 for preventing soot from falling into the living area and for accommodating the soot collection ring 2 . The soot collection ring 2 includes two half rings, one end of each...

Abstract

The invention discloses a chimney top soot prevention structure. The chimney top soot prevention structure comprises a chimney rear enclosure wall obliquely arranged relative to the horizontal plane.A soot collecting ring is detachably arranged on the inner wall of a chimney, and an inclined plate used for preventing soot from falling into a living area and containing the soot collecting ring isarranged at the lower end of the chimney rear enclosure wall. By improving the chimney rear enclosure wall, under the condition that the area of a windward side is not increased (the outfitting numberis possibly increased due to increase of the area of the windward side, and the cost is increased), the rear enclosure wall is obliquely designed, the soot collecting area is increased, soot can be concentrated to the top of the chimney along an oblique plane, and centralized treatment is facilitated. The appearance of the chimney is simply changed without influencing the appearance. No windwardside is added in the structural design, and the cost is not increased. The soot is collected to the maximum extent, and the protection of the ship environment is ensured.

Description

technical field [0001] The invention relates to a soot prevention structure at the top of a chimney. Background technique [0002] The top of the chimney of a conventional ship is that the surrounding peripheral walls extend directly upwards for a certain distance, and the sides are usually made with a slope (such as figure 1 Show). The chimneys are all made very high, generally exceeding the compass deck built above, and its main purpose is to prevent the soot from falling into the living area. However, many shipowners have reported that the soot at the tail of the chimney will fall to the aft deck area and affect the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a soot-proof structure at the top of the chimney. The shape of the chimney is only changed simply without affecting the appearance; the structural design does not increase the windward side and does not increase the c...
