Description
Technical field
Originally it is bright to belong to boiler component technical field, and in particular to a kind of combined-type evaporator.
Background technology
With the continuous improvement of living standards of the people, MSW heating value is also constantly raised.To tackle the change of refuse thermal value
Dynamic, garbage burning boiler need to accordingly increase heating surface.Usual large-sized boiler furnace chamber includes burner hearth, burning chamber, three flues, heating surface
Typically it is all disposed within three flues.The method of common increase heating surface has two kinds：Boiler whole height is lifted, or reduces heated
Face pitch.But construction cost can be greatly increased by lifting boiler height, and reduce pitch then easy dust deposition, to high temperature superheater
Corrosion is produced Deng heating surface.In addition, for the garbage burning boiler put into operation, with the continuous rise of refuse thermal value, flue gas temperature
Spend more and more higher, high temperature corrosion is on the rise, and three flues often increase heating surface without sufficient space, transform difficulty compared with
Greatly.
On the other hand, common evaporator tube bank generally all carries slanted angle, and connects header through water-cooling wall.The knot
Structure occupies space greatly, inconvenience sealing.
The content of the invention
Present invention solves the technical problem that be to provide it is a kind of make full use of space, be easy to sealing, group convenient for installation and maintenance
Box-like evaporator.
In order to solve the above-mentioned technical problem, technical scheme is as follows：
A kind of combined-type evaporator, including the tube bank of the first evaporator, the second evaporator tube bank, support, bracket, described first
Evaporator tube bank is arranged in burning chamber bottom, and the tube bank of the second evaporator is arranged at three stack bases, the tube bank of first, second evaporator
Entrance end is directly connected with corresponding water screen tube, and restrains the water screen tube between importing and exporting in first, second evaporator
Upper fluting loads restricting orifice, and the first, second evaporator tube bank other end is equipped with pipe clamp, and is fixed on separately by support, bracket
On one side wall.
Further, the first evaporator tube bank is spaced one by one with partition wall water screen tube, and the tube bank of the second evaporator is with after
Bag wall water screen tube corresponds arrangement.
Further, the first evaporator tube bank, the tube bank of the second evaporator are made up of multiple rows of bundle of parallel tubes.
Further, the first, second evaporator tube bank is in many pipeloop arrangements of shape.
Further, the support by comb plate, comb joint and gripper shoe groups into comb plate, comb joint is restrained installed in first, second evaporator
Lower section, and be fixed on by supporting plate on water-cooling wall.
Further, the bracket is made up of fill block, U-board and protrusive board, and U-board is welded on water-cooling wall by fill block,
Protrusive board is welded with the tube bank of first, second evaporator, protrusive board is placed in U-board groove.
Further, the support, bracket are made of stainless steel material.
Beneficial effects of the present invention are as follows：
1. garbage burning boiler superheater import cigarette temperature must be controlled below 650 °, due to the continuous improvement of refuse thermal value,
2 groups of evaporators need to be arranged before superheater, are respectively arranged in burning chamber bottom, three stack bases, to reduce superheater import cigarette
Temperature.
2. by the first evaporator tube bank be arranged in burning chamber bottom, can space efficient, reduce boiler whole height, subtract
Few cost of investment.In addition, the program is also applied for old boiler transformation, burning chamber's bottom space is made full use of, construction is simple, is easy to
Install.
3. the tube bank of the second evaporator is directly connected with rear bag wall water-cooling wall, it is to avoid evaporator is restrained through rear bag wall water cooling
Wall, is conducive to sealing.
4. support, carrier structure are simple, easy for installation, it can both ensure to restrain transverse pitch, also reserve expansion clearance.
In tube bank bend pipe end arrangement pipe clamp, it can be ensured that each pipeloop longitudinal pitch, then stress is conducive to support close to support.
5. evaporator tube row is in shape multitube ring formula, at utmost increase heating surface area in unit area, to reach
The purpose of high efficient heat exchanging.
6. because partition wall water-cooling wall pitch is generally 80~100mm, the tube bank of the first evaporator and partition wall water screen tube are one by one
It is spaced, widens pitch between pipe, it is to avoid dust stratification.
7. and rear water wall pitch is generally 150~180mm, the tube bank of the second evaporator and rear bag wall water screen tube are one by one
Correspondence, you can avoid dust stratification, increase tube bank quantity increases heating surface area.
Load 8. being slotted compared with restricting orifice of the traditional welding in inside tube, on the water screen tube between import and export
Restricting orifice, can be welded on the outside of pipe, simple and reliable for structure, difficult for drop-off.
9. support, bracket use stainless steel material, corrosion-resistant and high-temperature resistant.
In summary, after using the said structure of the present invention, be conducive to controlling the inlet temperature of superheater；Make full use of
Space is limited, at utmost increases heating surface area；It is its compact conformation, easy for installation, it is adaptable to the heating surface arrangement of a variety of boilers.
