Description
Technical field
The utility model relates to biomass energy apparatus field more particularly to a kind of anti-corrosions suitable for fluidized-bed gasification furnace
Erosion, anti-wear distributor.
Background technique
Fluidized-bed gasification furnace can make full use of the high-intensitive heat transfer and mass transfer in bed between gas-particle two-phase, make entire bed
Interior uniformity of temperature profile, mixing condition is good, is conducive to the progress of gasification reaction.Fluidized-bed gasification furnace has efficient, inexpensive, steady
Calmly, the advantages such as clean and environmental protection, gasifying agent are diversified, start-stop furnace facilitates, therefore be widely used now.
However, furnace atmosphere includes carbon, dust, sulphur, oxygen, steaming under high temperature, high pressure operating condition in fluidized-bed gasification furnace
The media such as vapour, hydrogen, distribution grid (device) are in furnace high-temperature zone position, and 1000 DEG C or so of high temperature is situated between plus the corrosivity in furnace
Matter and coal, the washing away of clinker, corrasion, working environment locating for (vapour) gas distribution grid (device) in gasification furnace is very harsh,
In such harsh environment, oxidation, vulcanization, carburizing, dirt, wear or intercouple effect all moment affect distribution grid
Service life.
Therefore, there is presently no a kind of anticorrosions for fluidized-bed gasification furnace, anti-wear distributor.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of anticorrosions suitable for fluidized-bed gasification furnace, abrasionproof
Damage distributor.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of suitable for the anti-of fluidized-bed gasification furnace
The anti-wear distributor of burn into, including separation layer, fixed device, wearing layer, short tube, distribution grid and distribution hole, the separation layer cover
It covers in the distribution plate surface, for the fixed device between the wearing layer and the distribution grid, the short tube is located at institute
It states in wearing layer, the distribution hole is distributed on the distribution grid with corresponding position where the short tube and connects with the short tube
It is logical.
The separation layer is high temperature resistant, anti abrasive alloy powder structure, the alloyed powder as a preferred technical solution,
The granular size at end is 15-40 μm.
The separation layer uses supersonic flame spraying technology or plasma spraying technology as a preferred technical solution,
The alloy powder is equably ejected into the surface of the distribution grid, the surface of the distribution grid is made to form one layer of extremely densification
Coat of metal, by the H in the distribution plate surface and its weld seam and furnace2The pernicious gases such as S are thoroughly isolated, to play guarantor
Protect and extend the effect of the distributor service life.
The wearing layer is high temperature resistant, wear-resisting heavy castable as a preferred technical solution, can be effective against furnace
The impact of slag, coal grain.
The fixed device is anchor studs or hexsteel as a preferred technical solution,.
By adopting the above-described technical solution, the beneficial effects of the utility model are: the separation layer of the utility model is protected
The corrosion of distributor and its weld seam from medium；Wearing layer prevents clinker in furnace, coal grain to the washing away of distributor, denudes.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structure chart of the utility model embodiment.
Specific embodiment
For technology contents, the construction feature that the utility model is described in detail, below in conjunction with embodiment and cooperate attached drawing detailed
Carefully it is explained.
A kind of anticorrosion suitable for fluidized-bed gasification furnace, anti-wear distributor, including it is separation layer 1, fixed device 2, resistance to
Grind layer 3, short tube 4, distribution grid 5 and distribution hole 6.
As shown in Figure 1, separation layer 1 is covered on 5 surface of distribution grid, device 2 is fixed between wearing layer 3 and distribution grid 5,
Short tube 4 is located in wearing layer 3, and distribution hole 6 is distributed on distribution grid 5 with the 4 place corresponding position of short tube and connects with short tube 4
It is logical, enable steam by distribution hole 6 and short tube 4 through distribution grid 6, separation layer 1 and wearing layer 3.
Separation layer 1 is high temperature resistant, anti abrasive alloy powder structure, and the granular size of alloy powder is 15-40 μm, is led to
Crossing modern spraying technology makes it form fine and close metallic spacer 1 with 5 surface of distribution grid, when in fluidized-bed gasification furnace furnace
O2、N2、CO、H2、CH4、H2When S and vapor etc. contact 5 inner surface of distribution grid, separation layer 1 can resist H2The oxygen of the gases such as S
Change, vulcanization, nitridation etc. are corroded, and can resist 1000 DEG C or more of reaction temperature.
Wearing layer 3 is high temperature resistant, wear-resisting heavy castable, is coupled between wearing layer 3 and distribution grid 5 with fixed device 2,
Clinker left after feed coal grain used in fluidized-bed gasification furnace industrial processes and reaction etc. can generate punching to distributor
It hits, wearing layer 3 can be effective against the impact of clinker, coal grain, to substantially increase wear-resistant, the shock proof energy of distribution grid
Power.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.Current row
