Description
Technical field
The utility model belongs to Sector of Cfb Boilers, is specifically related to a kind of circulating fluid bed boiler cyclone separator.
Background technology
China is the maximum country of number of units of CFBB installation in the world, and CFBB has day by day become the indispensable important component part in thermal power generation field.Be subject to using the impact of the factors such as coal is poor, the fault rate of CFBB is higher, and wherein cyclone separator fault is a subject matter that affects the efficient operation of CFBB long period.
Cyclone separator is the visual plant of CFBB separating cycle material, and its effect is to utilize centrifugation principle that particle separation and collection from flue gas out, is completed to the cyclic process of material through material returning device loopback.If cyclone separator breaks down, this can bring following problem: (1) fine grained can not get the performance driving economy that active combustion affects boiler; (2) flying dust amount increases the wearing and tearing of aggravation back-end surfaces, increases the energy consumption of cleaner; (3) the circulating ash quantity that enters closed circuit reduces, and internal circulating load declines, and affects Heat Transfer in Furnace characteristic; (4), if cyclone separator stops up, boiler will be forced to the maintenance of stopping using.
Cyclone separator work under bad environment, due to velocity of flue gas high (20m/s～30m/s), ash particle is thick and concentration is high, high dust-contained airflow is easy to cause the wearing and tearing of air-flow contact area Fire and abrasion resistant material while occurring sharply to rotate.Meanwhile, cyclone separator is generally laid with thicker Fire and abrasion resistant material, when startup and load variations, than being easier to, occurring larger thermograde and localized hyperthermia and causes coming off of Fire and abrasion resistant material.According to statistics, in cyclone separator fault, approximately having half is that Fire and abrasion resistant material wearing and tearing and coming off cause.
Cyclone separator Fire and abrasion resistant material wearing and tearing and the concrete reason coming off comprise: high dust-contained airflow washes away that the wearing and tearing, thermal stress and the mechanical stress that cause cause comes off, Fire and abrasion resistant material physicochemical characteristics changes the damage causing.
It is high dust-contained airflow to strongly the washing away of Fire and abrasion resistant material that high dust-contained airflow washes away the wearing and tearing main manifestations causing, and these class wearing and tearing aggravate with the increase of air-flow dust content, velocity of flue gas, are also subject to the impact of high dust-contained airflow projected angle of impact simultaneously; When the main manifestations that comes off that thermal stress and mechanical stress cause is startup and load variations, the stress of temperature fluctuation, thermal shock and machinery causes Fire and abrasion resistant material produce crack and peel off; It is mainly affected by alkali metal, microparticle infiltration in flue gas that Fire and abrasion resistant material physicochemical characteristics changes the damage causing, and finally causes Fire and abrasion resistant material gradually corrosion failure and rotten destruction.
Conventional method generally by improving construction technology, improve material quality, reduce velocity of flue gas, control the means such as heating rate and control, but limited more and effect is limited.
For example utility model patent 201020177453.9 discloses a kind of Multi-step arc buffering abrasion resisting device, and the arc abrasionproof buffering slope of thickness 100～200mm is set on separator wall by heat resisting steel anchoring piece and refractory material.The method essence is a kind of passive abrasionproof mode (root that wearing and tearing produce is not thoroughly eliminated), and the thickness that increases refractory material can increase the risk that come off by thermal stress.Because arc abrasionproof buffering slope has changed the flow field of having flowed, destroy cyclone separator of air-flow in cyclone separator cylindrical shell, this can have a negative impact to the safety and economic operation of boiler especially.
For example utility model patent 01123924.7 discloses a kind of gas-solid cyclone separation method and device thereof that reduces wearing and tearing again, by opening being set on cylindrical shell wall, for separating of a part of dust-contained airflow.This mode, except on-the-spot installation difficulty, can be destroyed flow field, the reduction separative efficiency of separator equally, reduces the economy of CFBB operation.
Utility model patent 201010602889.2 discloses a kind of cyclone separator of circulating fluidized bed boiler, and it builds the wear-resistant material on corrugated surface in flue inwall and target area, and at separator inlet, angle of declination is set.This mode has changed the mobile defence line of air-flow, can affect separative efficiency, and the surface construction of corrugated is very difficult, if the design of angle of declination is implemented in boiler improvement simultaneously, needs large area change boiler water wall, and transformation difficulty is large.

3, because the coefficient of expansion of high-strength fireproof wear-resistant material layer S is different from steel, its expansion and contraction cannot be synchronizeed with water screen tube 10 and separator shell 11, therefore high-strength fireproof wear-resistant material layer S is interior except having fixing pin 12, and the stainless steel fibre 13 that evenly gathers, thermal stress compensate for dilatation soon, have effectively been eliminated in heat conduction, improved intensity, avoided coming off.
4, high-strength fireproof wear-resistant material layer S arranges dilatation joint L every establishing 400mm～1500mm spacing, dilatation joint L and air current flow direction tilt different (being different from traditional vertical expansion seam), prevent permeate gas stream high-strength fireproof wear-resistant material layer, avoid the harmful components in flue gas to penetrate into high-strength fireproof wear-resistant material layer simultaneously, extended the life-span of high-strength fireproof wear-resistant material layer.
