AI Technical Summary
The traditional waste heat boiler island layout means that a larger area is needed on one side of the boiler to arrange the auxiliary computer room, resulting in too large area on the side.
By setting up a slope plate below the inlet flue of the vertical waste heat boiler, space is reserved to arrange the medium-pressure water supply pump room, the frequency converter room, the sampling and dosing room, etc., and a high-pressure water supply pump room is arranged on one side of the boiler to reduce the floor area on the side of the boiler.
The floor area of the side of the waste heat boiler is effectively reduced and the efficient use of space is achieved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vertical waste heat boilers, in particular to an auxiliary machine room of a vertical waste heat boiler and an auxiliary equipment arrangement structure. Background Art
[0002] The gas-steam combined cycle has the characteristics of high overall efficiency and low pollution emissions. The combined cycle vertical waste heat boiler has the advantages of small footprint, convenient peak load operation and convenient maintenance. In the traditional waste heat boiler island layout, the auxiliary machine room is arranged on one side of the boiler, and the auxiliary machine room is equipped with high and medium pressure feed water pumps, preheater recirculation pumps, instrumentation and control electrical equipment rooms, and dosing sampling rooms. This layout requires a large area on one side of the boiler to arrange the auxiliary machine room, resulting in an excessively large area on the side. Summary of the invention
[0003] In order to solve the above technical problems, the utility model provides a vertical waste heat boiler auxiliary machine room and auxiliary equipment layout structure, which can effectively reduce the floor space occupied by the side of the waste heat boiler.
[0004] The technical solution is as follows: a vertical waste heat boiler auxiliary machine room and auxiliary equipment layout structure, which includes a vertical waste heat boiler body and an inlet flue, characterized in that an inclined plate is provided below the connection between the inlet flue and the vertical waste heat boiler body, and two layers of furnace bottom auxiliary machine rooms, an upper sampling room, a lower dosing room, and a frequency conversion room are arranged in sequence from high to low below the inclined plate, and a high-pressure water supply pump room is provided on one side of the inlet flue.
[0005] It is further characterized in that the angle between the inclined plate and the horizontal plane is 20°-30°;
[0006] The furnace bottom auxiliary machine room is connected to the steel structure of the vertical waste heat boiler body;
[0007] The first-floor auxiliary machine room is equipped with a medium-pressure water supply pump and a preheater recirculation pump, and the second-floor auxiliary machine room is equipped with an electronic equipment room and a power distribution room;
[0008] The high-pressure water supply pump room is arranged close to the frequency conversion room, and a No. 1 high-pressure water supply pump and a No. 2 high-pressure water supply pump are arranged in the high-pressure water supply pump room;
[0009] An elevator shaft is arranged beside the furnace bottom auxiliary machine room and the high-pressure water supply pump room.
[0010] After adopting the utility model, by adjusting the lower part of the inlet flue of the vertical waste heat boiler, sufficient space can be reserved below the inlet flue to arrange the medium-pressure feed water pump room, the frequency converter room and the sampling and dosing room, etc. by using an inclined plate. At the same time, the high-pressure feed water pump room is arranged only on one side of the vertical waste heat boiler, thereby reducing the area occupied by the side of the waste heat boiler to a minimum.

[0013] Figure 3 for Figure 1 Middle BB section; Figure 4 for Figure 1 Mid-CC section view. DETAILED DESCRIPTION
[0014] See Figures 1 to 4 The invention discloses a vertical waste heat boiler auxiliary machine room and auxiliary equipment arrangement structure, which comprises a vertical waste heat boiler body 1 and an inlet flue 2. An inclined plate is provided below the connection between the inlet flue 2 and the vertical waste heat boiler body 1. The angle between the inclined plate and the horizontal plane is 20°-30°. The space below the inlet flue 2 is reserved. Two layers of furnace bottom auxiliary machine room, an upper sampling room 3, a lower dosing room 4, and a frequency conversion room 5 are arranged in sequence below the inclined plate from high to low. A high-pressure water supply pump room 6 is provided on one side of the inlet flue 2.
[0015] The furnace bottom auxiliary machine room is connected to the steel structure of the vertical waste heat boiler body 1. The first-layer furnace bottom auxiliary machine room 7 is provided with a medium-pressure water supply pump 8 and a preheater recirculation pump 9. The second-layer furnace bottom auxiliary machine room 10 is provided with an electronic equipment room and a distribution room. Auxiliary machine room stairs 11 are provided on the outside of the first-layer furnace bottom auxiliary machine room 7 and the second-layer furnace bottom auxiliary machine room 10. Stairs are provided in the upper sampling room 3 and the lower dosing room 4 for up and down passage.
[0016] The high-pressure water pump room 6 is located near the frequency conversion room 5, and there are doors between them for easy inspection and maintenance of the two rooms. The high-pressure water pump room 6 is equipped with a No. 1 high-pressure water pump 6-1 and a No. 2 high-pressure water pump 6-2, so that one is used and the other is reserved. An elevator shaft 12 is provided beside the furnace bottom auxiliary machine room and the high-pressure water pump room 6.
[0017] In this application, only the high-pressure feed water pump room needs to occupy additional space outside the boiler area, which can minimize the space occupied by the furnace side.
