Abstract
The invention belongs to the technical field of boiler parts and particularly relates to a combined evaporator. The combined evaporator structurally comprises a first evaporator tube bundle, a second evaporator tube bundle, a support and a bracket. The first evaporator tube bundle is distributed at the bottom of a burnout chamber, the second evaporator tube bundle is arranged at the bottoms of three flues, the inlet and outlet ends of the evaporator tube bundles are directly connected with corresponding water-cooling wall tubes, grooves are formed in the water-cooling wall tubes between inlets and outlets, and throttle orifice plates are installed in the grooves. The other end of each tube bundle is fixed to the water-cooling wall on the other side through the support and the bracket. By means of the structure, inlet smoke temperature of a superheater can be effectively lowered, limited space is fully used, the heating area is effectively increased, and the combined evaporator is compact in structure, convenient to install and suitable for distribution of heating faces of various boilers.
Description
Technical field
This bright boiler component technical field that belongs to, is specifically related to a kind of combined-type evaporator.
Background technology
Along with improving constantly of living standards of the people, MSW heating value also constantly raises. For the change of reply refuse thermal valueMoving, garbage burning boiler needs corresponding increase heating surface. Conventionally large-sized boiler furnace chamber comprises burner hearth, burning chamber, three flues, heating surfaceGenerally all be arranged in three flues. The method of common increase heating surface has two kinds: lift boiler whole height, or dwindle and be heatedFace pitch. Can greatly increase construction cost but lift boiler height, dwindle easy dust deposition of pitch, to high temperature superheaterProduce corrosion Deng heating surface. In addition, for the garbage burning boiler having put into operation, along with the continuous rising of refuse thermal value, flue gas temperatureSpend more and more highlyer, high temperature corrosion is on the rise, and three flues often do not have sufficient space to increase heating surface, and transformation difficultyGreatly.
Another aspect, common evaporimeter is restrained conventionally all with slanted angle, and connects header through water-cooling wall. This knotIt is large that structure occupies space, inconvenience sealing.
Summary of the invention
The technical problem that the present invention solves is to provide and a kind ofly makes full use of space, is convenient to sealing, group convenient for installation and maintenanceBox-like evaporimeter.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows:
A kind of combined-type evaporator, comprises the first evaporimeter tube bank, the second evaporimeter tube bank, support, bracket, described the first evaporationOrgan pipe bundle is arranged in burning chamber bottom, and the second evaporimeter tube bank is arranged at three flue bottoms, first, second evaporimeter tube bank turnoverDirect and the corresponding water screen tube of mouth end is connected, and opens on the water screen tube between first, second evaporimeter tube bank import and exportGroove packs restricting orifice into, and first, second evaporimeter tube bank other end is equipped with pipe clamp, and is fixed on opposite side by support, bracketOn water-cooling wall.
Further, the first evaporimeter tube bank is spaced one by one with partition wall water screen tube, the second evaporimeter tube bank with afterBag wall water screen tube corresponding layout one by one.
Further, described the first evaporimeter tube bank, the second evaporimeter tube bank form by arranging bundle of parallel tubes more.
Further, described first, second evaporimeter tube bank is shape multitube circle layout.
Further, described support is made up of comb plate, comb joint and gripper shoe, and comb plate, comb joint is arranged on first, second evaporimeter tube bankBelow, and be fixed on water-cooling wall by gripper shoe.
Further, described bracket is made up of fill block, U-shaped plate and flange, and U-shaped plate is welded on water-cooling wall by fill block,In first, second evaporimeter tube bank, be welded with flange, flange is placed in U-shaped plate groove.
Further, described support, bracket adopt stainless steel material to make.
Beneficial effect of the present invention is as follows:
1. garbage burning boiler superheater import cigarette temperature must be controlled at below 650 °, due to improving constantly of refuse thermal value, and need beBefore superheater, arrange 2 groups of evaporimeters, be arranged in respectively burning chamber bottom, three flue bottoms, to reduce superheater import cigarette temperature.
2. the first evaporimeter tube bank is arranged in to burning chamber bottom, can space efficient, reduce boiler whole height, subtractFew cost of investment. In addition, this scheme is also applicable to old boiler transformation, makes full use of burning chamber's bottom space, and construction is simple, is convenient toInstall.
3. the second evaporimeter tube bank is directly connected with rear bag wall water-cooling wall, has avoided evaporimeter to restrain through rear bag wall water-cooledWall, is conducive to sealing.
4. support, carrier structure are simple, easy for installation, both can ensure to restrain transverse pitch, have also reserved expansion clearance.Arrange pipe clamp at tube bank bend pipe end, can guarantee each pipeloop longitudinal pitch, be conducive to stressed support near support.
5. evaporator tube row is shape multitube circle pattern, at utmost increases heating surface area, to reach in unit areThe object of high efficient heat exchanging.
6. because partition wall water-cooling wall pitch is generally 80～100mm, the first evaporimeter tube bank and partition wall water screen tube are one by oneBe spaced, widen pitch between pipe, avoid dust stratification.
7. and rear water wall pitch is generally 150～180mm, the second evaporimeter tube bank and rear bag wall water screen tube are one by oneCorrespondence, can avoid dust stratification, increases tube bank quantity, strengthens heating surface area.
With traditional welding compared with the restricting orifice of inside tube, on the water screen tube between importing and exporting, slot and pack intoRestricting orifice, can weld in pipe outside, simple and reliable for structure, difficult drop-off.
9. support, bracket adopt stainless steel material, corrosion-resistant and high-temperature resistant.
In sum, adopt after said structure of the present invention, be conducive to control the inlet temperature of superheater; Make full use ofLimit space, at utmost increases heating surface area; Its compact conformation, easy for installation, the heating surface that is applicable to multiple boiler is arranged.
