Description
Technical field
The utility model is related to a kind of boiler furnace water-cooling wall, particularly a kind of novel anti-abrasion CFBB combustion
Burn room water-cooling wall.
Background technology
CFBB (CFB) technology is that a high-efficiency low-pollution cleans coal combustion technology, circulating fluidized bed boiler water
Cold wall is the important heating surface of boiler, is the vitals for ensureing high efficiency boiler operation.Solid in CFB Boiler Operation
Body particle is very serious to the thinning problem of the high temperature wear of the heating surfaces such as water-cooling wall, especially near cyclone inlet
Water-cooled wall region, as in the region, flow velocity is larger, turbulent extent is high, water screen tube in boiler water square abrasion upwards more
Seriously, abrasion pipe explosion accident seriously threatens the safe operation of CFBB.The abrasion of water-cooling wall shortens recycle stream
In the cycle that fluidized bed boiler continuously runs, operation and maintenance cost is increased, unit utilization rate is reduced；Abrasion becomes impact circulation
The maximum restraining factors of fluidized-bed combustion boiler long-term safety operation.
For above water-cooled wall of circulating fluidized bed wear problem, existing technology takes some measures, traditional abrasionproof
Measure has castable abrasionproof, installs anti-friction protecting watt etc. additional, but these Precautionary Measures occur new mill in the end of abrasionproof position
Damage phenomenon, Chinese utility model patent application number：201520515269.3, disclose " a kind of circulating fluid bed boiler prevent
Mill fin ", this device are to install distributing damper and deflector to avoid the solid in flue gas on boiler water wall fin
Abrasion of the grain to water screen tube, but contact of the flue gas with water-cooling wall is that it reduces, Local Heat Transfer amount is reduced, the warp to boiler
Ji benefit has a larger negative effect, and such apparatus structure installs complex, and therefore, Chinese utility model is special
Sharp application number：There is above-mentioned deficiency in disclosed 201520515269.3 " a kind of circulating fluid bed boiler abrasionproof fin ".
Content of the invention
Technical problem to be solved in the utility model is to carry out substantial improvements and innovation to prior art, there is provided a kind of
Simple and reasonable, it is easy to install and implement, be both avoided that solid particle was to water screen tube in burning in circulating fluid bed boiler room
Abrasion, the novel anti-abrasion burning in circulating fluid bed boiler room water-cooling wall of boiler thermal output can not be affected again.
The utility model provides a kind of novel anti-abrasion burning in circulating fluid bed boiler room water-cooling wall, water screen tube, water-cooled
Fin, the distributing damper being arranged on fin between wall pipe, the distributing damper at least two longitudinally perpendicular setting of being spaced
Put on fin, the distributing damper is provided with smoke ventilator.
Smoke ventilator on distributing damper can allow flue gas to pass through, and shunt plate washer and can block the solid carried in flue gas
Grain so that flue gas can be fully contacted with water screen tube, but the solid particle in flue gas is blocked without making to water screen tube
Into abrasion.
Further, the smoke ventilator is opened in distributing damper and is contacted with fin on the side of side, the smoke ventilator
Be spaced is arranged on distributing damper, and the smoke ventilator on two adjacent distributing dampers is interwoven.
Smoke ventilator is arranged on distributing damper and is contacted with fin on the side of side, it is ensured that flue gas and water screen tube fill
Tap is touched, and what the smoke ventilator was spaced is arranged on distributing damper, the smoke ventilator on two adjacent distributing dampers
Interwoven.First piece shunts the solid particle that plate washer has been blocked in part of smoke, and another part solid particle is through cigarette
Vent hole moves on through first piece of distributing damper, and the smoke ventilator of second piece of distributing damper is led to due to the flue gas with first piece
Hole is in interlaced arrangement, and therefore, remaining solid particle is stopped by second piece of distributing damper, and flue gas can be light due to inertia very little
Malleable is flowed to, and therefore further ensuring flue gas can be fully contacted with water screen tube by two pieces of distributing dampers, and flue gas
In solid particle be split baffle so as to preventing water screen tube to be worn.
Further, the smoke ventilator is comb shape smoke ventilator.
The circulation area of comb shape smoke ventilator is larger, is more beneficial for cigarette while solid particle is blocked in flue gas is ensured
Gas passes through.
Further, the comb shape smoke ventilator along water screen tube radial direction height for water screen tube radius 0.5-2
Times, the width along water screen tube axial direction is 1-5cm, is spaced 2-10cm between two adjacent comb shape smoke ventilators.
Further, the comb shape smoke ventilator is identical along the height of water screen tube radial direction and the radius of water screen tube, edge
The width of water screen tube axial direction is 2cm, is spaced 4cm between two adjacent comb shape smoke ventilators.
The size design of comb shape smoke ventilator has a significant impact to the heat exchange of flue gas and water screen tube, it is ensured that heat exchange
Effect and water screen tube abrasionproof effect.
Further, water-cooling wall of the distributing damper near the cyclone inlet of CFBB
On region.
Water-cooled wall region near the cyclone inlet of CFBB, due in the region flue gas flow rate compared with
Greatly, turbulent extent is high, and abrasion of the water screen tube in boiler water square upwards is the most serious, and abrasion pipe explosion accident seriously threatens and follows
The safe operation of circulation fluidized bed boiler, arranges distributing damper best results on the fin in this region.
The utility model compared with the existing technology has advantages below and effect：
1st, rational in infrastructure, install and easy to implement.
2nd, flue gas can be normal through the particle in flue gas is blocked, and is effectively guaranteed water screen tube and is not worn.
3rd, the heat transfer effect of boiler, while protecting water screen tube not frayed, is not affected.
4th, the operating cost of enterprise is reduced.
