Abstract
The utility model discloses a kind of fixed structure of CFBB zirconium chromium carborundum Wear-resistant corrosion-resistant plastic layer, and the fixed structure is distributed in boiler hearth of circulating fluidized bed top, outlet, separator inlet flue, target area, standpipe, material returning device, burner hearth emulsion zone air distribution plate, air port, coal feeding hole and material inlet, curtain wall, temperature and pressure-measuring-point；Including the plastic bed of material of zirconium chromium carborundum Wear-resistant corrosion-resistant being fixed on by special-shaped bitch on water screen tube, can augmentation of heat transfer, when there is local loosen avoiding moldable entirety comes off.
Description
Technical field
The utility model is related to CFBB abrasion techniques field, more particularly to a kind of CFBB zirconium
Chromium carborundum Wear-resistant corrosion-resistant plastic layer fixed structure.
Background technology
CFBB has the advantages that pollutant is low, fuel tolerance is wide, at home and abroad obtains in the late three decades
Fast development, the 15% of the coal-fired thermal power generation total installation of generating capacity of installed capacity Yi Zhan China that current recirculating fluidized bed generates electricity.By
Burning coal, lectotype selection and the influence of service condition, the serious wear of CFBB, therefore it is big in region easy to wear
Amount lays Fire and abrasion resistant material.
The granular and powdery that Fire and abrasion resistant material is typically made up of refractory materials such as bauxite chamotte, corundum and carborundum
Material, adds a certain proportion of aluminate cement bonding agent or water, and some additives allotments are mixed outside and are formed, according to castable and plastic
The difference of material, can be using cast or mode of vibration shaping.
Fire and abrasion resistant material composition is larger on performance and use cost influence, although carborundum (SiC) and silicon nitride
(Si3N4), corundum (pure Al2O3) etc. material refractoriness it is high, wearability is good but expensive, heat endurance is poor.It is ciculation fluidized
Load is changeable during use for bed boiler, and the startup cycle is long, and temperature change frequently, flow by the region such as burner hearth emulsion zone, separator target area
Fast high, impact wear is big, is influenceed by burning coal difference, flue gas O2Content is high and contains corrosive gas, the lime-ash such as NOx, SOx
In be rich in SO3、Na2O、K2The materials such as O, these can cause strong influence to the service life of Fire and abrasion resistant material.
In addition, traditional Fire and abrasion resistant material complicated construction technique, Site, additive amount, bonding agent consumption, addition
The factor such as agent and bonding agent quality, curing temperature, baker process can produce shadow to the macro property of Fire and abrasion resistant material, life-span
Ring.
The content of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of CFBB
The moldable fixed structure of zirconium chromium carborundum Wear-resistant corrosion-resistant, can overcome conventional material and fixed form to lead using the fixed structure
Hot property is poor, easily come off, and the drawbacks of material perishable damage.
In order to achieve the above object, the utility model is adopted the following technical scheme that：
A kind of fixed structure of CFBB zirconium chromium carborundum Wear-resistant corrosion-resistant plastic layer, the fixed structure point
Cloth is at the top of boiler hearth of circulating fluidized bed, outlet, separator inlet flue, target area, standpipe, material returning device, burner hearth emulsion zone cloth
Aerofoil, air port, coal feeding hole and material inlet, curtain wall, temperature and pressure-measuring-point；Including being fixed on water by special-shaped bitch 2
The plastic bed of material 3 of zirconium chromium carborundum Wear-resistant corrosion-resistant on cold wall pipe 1.
Dilatation joint is provided with the plastic bed of material 3 of zirconium chromium carborundum Wear-resistant corrosion-resistant.
The special-shaped bitch 2 is shaped as V-type, Y types, T-shaped, L-type, Z-type or dendroid Y-shaped.
The beneficial effects of the utility model：
1) material itself corrosion resistance is strong, has stronger resistivity to harmful gas, dust；
2) the different pin of structure type is selected according to diverse location, is easy to in-site installation construction to be laid with moldable；
3) pin has the predetermined capacity of heat transmission, helps to prevent temperature shock, thermal shock resistance is improved.

Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of the utility model CFBB zirconium chromium carborundum Wear-resistant corrosion-resistant plastic layer is consolidated
Determine structure, the fixed structure is distributed in boiler hearth of circulating fluidized bed top, outlet, separator inlet flue, target area, vertical
Pipe, material returning device, burner hearth emulsion zone air distribution plate, air port, coal feeding hole and material inlet, curtain wall, temperature and pressure-measuring-point；Including
The plastic bed of material 3 of zirconium chromium carborundum Wear-resistant corrosion-resistant on water screen tube 1, the zirconium chromium carborundum are fixed on by special-shaped bitch 2
Steel fibre 4 is added with the plastic bed of material 3 of Wear-resistant corrosion-resistant, can augmentation of heat transfer, avoided when there is local loosen moldable
Entirety come off.
As preferred embodiment of the present utility model, as shown in figure 3, the special-shaped bitch 2 be shaped as V types, Y types,
T-shaped, L-type, Z-type or dendroid Y-shaped.
As shown in Fig. 2 being fixed on water cooling by the special-shaped bitch of V-type for the plastic bed of material 3 of zirconium chromium carborundum Wear-resistant corrosion-resistant
On wall pipe 1.
As preferred embodiment of the present utility model, set on the plastic bed of material 3 of zirconium chromium carborundum Wear-resistant corrosion-resistant
There is a dilatation joint, dilatation joint is through moldable construction layer.
