Abstract
The utility model relates to an exhaust -heat boiler's interior heat preservation structure. The utility model discloses a stove outer covering, the heat preservation between stove outer covering and the inner casing is located to the inner casing, still includes inlayer mounting and outer mounting, and the heat preservation internal fixation has the connecting piece, outer mounting and stove outer covering and connecting piece fixed connection, inlayer mounting and connecting piece and inner casing fixed connection, the inlayer mounting is coincident mutually with the hookup location of connecting piece with the hookup location and the outer mounting of connecting piece. The utility model discloses the heat that can make high temperature flue gas in the flue is in the conduction step by step through inlayer mounting, connecting piece and outer mounting and obtain the decay to the stove outer covering temperature reduces by a wide margin, heat energy runs off reduces by a wide margin, same sample plot, the vibration audio frequency of flue gas is weakened at the in -process through inlayer mounting, connecting piece and the conduction of outer mounting step by step, makes the noise reduced by a wide margin. Therefore, the utility model provides a technical problem that the exhaust -heat boiler high -temperature area noise exceeds standard and the super temperature of stove outer covering, heat energy run off among the prior art.
Description
Technical field
the utility model relates to a kind of heat insulation layer structure, particularly relates to a kind of inner thermal insulating layer structure of waste heat boiler.
Background technology
gas-steam combined cycle set waste heat boiler generally adopts inner thermal insulating layer, existing waste heat boiler typical case's inner thermal insulating layer structure (as shown in Figure 1), is made up of with the fixture 7 etc. of inner casing 4 heat-insulation layer 3, inner casing 4, connection furnace shell 1.There is following defect when waste heat boiler runs in the inner thermal insulating layer structure of this waste heat boiler: due at waste heat boiler flue entrance area, the flue gas entering waste heat boiler has the advantages that flue-gas temperature is high, flue gas flow rate is fast, and fixture 7 connects inner casing 4 and furnace shell 1 throughly, thus the high frequency noise of flue gas and high heat can be directly transferred to furnace shell 1 by fixture 7 by flue, and noise exceeds standard, the technological deficiency of furnace shell overtemperature and heat energy loss to cause waste heat boiler high-temperature area to also exist.
Summary of the invention
the utility model fixture mainly solved existing for prior art the high frequency noise in flue and high heat are directly conducted to furnace shell cause waste heat boiler high-temperature area to exist noise exceeds standard, the technological deficiency of furnace shell overtemperature and heat energy loss, a kind of inner thermal insulating layer structure making the noise of waste heat boiler high-temperature area and the temperature of furnace shell all declines to a great extent, heat energy loss significantly reduces waste heat boiler is provided.
the utility model is mainly solved by following technical proposals for the technical problem of above-mentioned existence: the utility model comprises furnace shell, inner casing, be fixed on the heat-insulation layer between furnace shell and inner casing, it is characterized in that: also comprise internal layer fixture and outer fixture, heat-insulation layer internal fixtion has connector, the two ends of outer fixture are fixedly connected with connector with furnace shell respectively, the two ends of internal layer fixture are fixedly connected with inner casing with connector respectively, and link position and the outer fixture of internal layer fixture and connector do not overlap with the link position of connector.
as preferably, outer fixture and internal layer fixture adopt bolt arrangement, and one end of outer fixture and furnace shell are welded and fixed and the other end and connector are spirally connected fixing, and one end of internal layer fixture and connector are welded and fixed and the other end and inner casing are spirally connected fixing.
as preferably, connector adopts angle steel.
the utility model structure has the following advantages:
1, the fixture connecting furnace shell and inner casing is divided into outer fixture and internal layer fixture by arranging connector in heat-insulation layer by the utility model, the internal layer fixture contacted with high-temperature flue gas is not directly contacted with furnace shell, because the heat of high-temperature flue gas in flue is through the conduction step by step of internal layer fixture, connector and outer fixture, its thermal resistance significantly increases and heat conduction temperature significantly reduces, thus overcomes the technological deficiency of furnace shell overtemperature, heat energy loss in prior art;
2, the utility model is owing to have employed inside and outside layer anchor structure, the vibration audio frequency of flue gas is weakened step by step in the process by inside and outside layer fixture conduction, thus noise significantly reduces, thus solves the technological deficiency that waste heat boiler high-temperature area noise exceeds standard.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of prior art;
accompanying drawing 2 is structural representations of the present utility model.
Detailed description of the invention
below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
embodiment 1: as shown in Figure 2, the utility model comprises furnace shell 1, inner casing 4, be located at the heat-insulation layer 3 between furnace shell 1 and inner casing 4, also comprise the internal layer fixture 6 and outer fixture 2 that adopt bolt arrangement, connector 5 is provided with in heat-insulation layer 3, connector 5 adopts angle steel, one end of outer fixture 2 and furnace shell 1 are welded and fixed and the other end and angle steel are spirally connected fixing, one end of internal layer fixture 6 and angle steel are welded and fixed and the other end and inner casing 4 are spirally connected fixing, internal layer fixture 6 does not coincide with the link position of angle steel and the link position of outer fixture 2 and angle steel.
the utility model is when waste heat boiler runs, because the internal layer fixture 6 contacted with high-temperature flue gas does not directly contact with furnace shell 1, in flue, the heat of high-temperature flue gas is through the conduction step by step of internal layer fixture 6, connector 5 and outer fixture 2, and its thermal resistance significantly increases and heat conduction temperature significantly reduces; Similarly, the vibration audio frequency of flue gas is weakened step by step in the process of being conducted by internal layer fixture 6, connector 5 and outer fixture 2, and noise is significantly reduced.Thus, the utility model solve waste heat boiler high-temperature area noise exceed standard and furnace shell overtemperature, heat energy loss technological deficiency.
certainly, above-mentioned drawings and Examples only in order to for explain and illustrate the utility model, can not as improper restriction of the present utility model.As connector 5 of the present utility model can also adopt band steel, channel-section steel etc. except adopting angle steel; and internal layer fixture 6 and outer fixture 2 can also adopt the versions such as riveted joint, welding except adopting bolt arrangement and being spirally connected, all those skilled in the art make equivalence adjustment according to the utility model and to change and the technical scheme that obtains all falls into protection domain of the present utility model.
