Description
Technical Field
The utility model relates to a waste incinerator technical field specifically is a waste incinerator steam pocket and downtake arrangement structure.
Background
The steam pocket and the downcomer system of the waste incineration boiler are important component parts of the waste incineration boiler, the prior structure is shown in figure 1, in the figure, 1 is the steam pocket, 2 is a main downcomer, 4 is a water wall, 6 is a boiler expansion center, 7 is an auxiliary downcomer, the steam pocket 1, the main downcomer 2, the auxiliary downcomer 7 and the water wall 4 are all connected with a boiler top plate 5 through a hanging support mechanism 3, the main downcomer 2 and the auxiliary downcomer 7 are uniformly distributed on one side of a boiler expansion center line, the structure occupies a large space, in the actual operation process, the pipeline stress is large, and potential safety hazards exist.
Disclosure of Invention
In order to solve the problems of large occupied space and large pipeline stress, the utility model provides a garbage furnace steam pocket and downcomer arrangement structure, which can reduce pipeline stress and occupied space.
The technical scheme is as follows: the utility model provides a rubbish stove steam pocket and downcomer arrangement structure, its includes steam pocket, main downcomer, vice downcomer, water-cooling wall, main downcomer upper end with vice downcomer upper end all is connected the steam pocket, its characterized in that, the steam pocket with main downcomer equipartition is arranged in boiler expansion center line, main downcomer is the vertical pipe, vice downcomer sets up in main downcomer one side, steam pocket, water-cooling wall, vice downcomer all connect the boiler roof through hanging supporting mechanism.
Adopt the utility model discloses afterwards, arrange the steam pocket in boiler expansion center line with main downcomer equipartition on for exhaust-heat boiler steam pocket and main downcomer and boiler water-cooled wall system expansion direction are unanimous, and the expansion system of steam pocket and downcomer system is further optimized, has reduced pipeline stress, simplifies the hanging bearing structure of boiler heating surface and downcomer system simultaneously, has saved the supporting mechanism that hangs of original main downcomer, makes product structure arrange compactly, reduces occupation space.
Drawings
FIG. 1 is a schematic diagram of a prior art structure;
fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 2, a garbage furnace steam drum and downcomer arrangement structure includes a steam drum 1, a main downcomer 2, an auxiliary downcomer 7, and a water wall 4, the upper end of the main downcomer 2 and the upper end of the auxiliary downcomer 7 are both connected with the steam drum 1, the steam drum 1 and the main downcomer 2 are both uniformly arranged on a boiler expansion center line 6, the main downcomer 2 is a vertical pipe, the auxiliary downcomer 7 is arranged on one side of the main downcomer 2, the steam drum 1, the water wall 4, and the auxiliary downcomer 7 are all connected with a boiler top plate 5 through a hanging support mechanism 3, and the hanging support mechanism in this embodiment is a joint commonly used in the existing boiler.
The utility model discloses improved the position relation between arranging and boiler expansion center line 6 of steam pocket 1 and main downcomer 2, arranged steam pocket 1 and main downcomer 2 in the position with boiler expansion center line 6 coincidence in boiler depth direction for exhaust-heat boiler steam pocket 1 and main downcomer 2 are unanimous with 4 systematic expansion directions of boiler water-cooling wall, and the expansion system of steam pocket 1 and downcomer system is further optimized, reduces pipeline stress. Meanwhile, the stress supporting structure of the boiler heating surface and the downcomer system is simplified, and the original hanging supporting mechanism of the main downcomer is omitted, so that the product structure arrangement is compact. The arrangement mode is adopted on a medium-temperature medium-pressure 600 ton/day waste incineration boiler, and the effect is good.
