Description
Technical field
Basis is the brightest belongs to boiler component technical field, 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 the most constantly raises.For tackling the change of refuse thermal value
Dynamic, garbage burning boiler need to increase heating surface accordingly.Generally 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: lift boiler whole height, or reduces and be heated
Face pitch.But lift boiler height and can be greatly increased construction cost, reduce pitch then easy dust deposition, to high temperature superheater
Corrosion is produced Deng heating surface.Additionally, for the garbage burning boiler put into operation, along with the continuous rising of refuse thermal value, flue gas temperature
Spending more and more higher, high temperature corrosion is on the rise, and three flues often do not have sufficient space to increase heating surface, and transformation difficulty is relatively
Greatly.
Another aspect, the tube bank of common vaporizer is generally all with slanted angle, and connects header through water-cooling wall.This knot
It is big that structure occupies space, and inconvenience seals.
Utility model content
This utility model solve the technical problem that be to provide one make full use of space, be easy to seal, convenient for installation and maintenance
Combined-type evaporator.
In order to solve above-mentioned technical problem, the technical solution of the utility model is as follows:
A kind of combined-type evaporator, including the first vaporizer tube bank, the second vaporizer tube bank, support, bracket, described first
Vaporizer tube bank is arranged in bottom burning chamber, and the second vaporizer tube bank is arranged at three stack base, first, second vaporizer tube bank
Entrance end is directly connected with corresponding water screen tube, and the water screen tube between first, second vaporizer tube bank is imported and exported
Upper fluting loads restricting orifice, and the first, second vaporizer tube bank other end is equipped with pipe clamp, and is fixed on separately by support, bracket
On one side wall.
Further, first vaporizer tube bank be spaced one by one with partition wall water screen tube, second vaporizer tube bank and after
Bag wall water screen tube one_to_one corresponding is arranged.
Further, described first vaporizer tube bank, the second vaporizer tube bank are made up of multiple rows of bundle of parallel tubes.
Further, many pipeloops layout in shape restrained by described first, second vaporizer.
Further, described support is made up of comb plate, comb joint and gripper shoe, and comb plate, comb joint is arranged on first, second vaporizer tube bank
Lower section, and be fixed on water-cooling wall by gripper shoe.
Further, described bracket is made up of fill block, U-board and flange, and U-board is welded on water-cooling wall by fill block,
Being welded with flange in first, second vaporizer tube bank, flange is placed in U-board groove.
Further, described support, bracket use stainless steel material to make.
The beneficial effects of the utility model are as follows:
1. garbage burning boiler superheater import cigarette temperature must control below 650 °, due to improving constantly of refuse thermal value,
2 groups of vaporizers need to be arranged before superheater, be respectively arranged bottom burning chamber, three stack base, to reduce superheater import cigarette
Temperature.
2. by first vaporizer tube bank be arranged in bottom burning chamber, can space efficient, reduce boiler whole height, subtract
Few cost of investment.Additionally, the program is also applied for old boiler transformation, making full use of burning chamber's bottom space, construction is simple, it is simple to
Install.
3. the second vaporizer tube bank is directly connected with rear bag wall water-cooling wall, it is to avoid vaporizer tube bank is through rear bag wall water-cooled
Wall, is conducive to sealing.
4. support, carrier structure are simply, easy for installation, both can ensure that tube bank transverse pitch, and have also reserved expansion clearance.
Arrange pipe clamp at tube bank bend pipe end, it can be ensured that each pipeloop longitudinal pitch, be then conducive near support stress to support.
5. vaporizer bank of tubes is shape multitube ring formula, at utmost increases heating surface area, to reach in unit are
The purpose of high efficient heat exchanging.
6. being generally 80～100mm due to partition wall water-cooling wall pitch, the first vaporizer tube bank is with partition wall water screen tube 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, second vaporizer tube bank with rear bag wall water screen tube one by one
Correspondence, can avoid dust stratification, increases tube bank quantity, strengthens heating surface area.
8. with traditional welding at the restricting orifice of inside tube compared with, import and export between water screen tube on fluting load
Restricting orifice, can weld outside pipe, simple and reliable for structure, difficult drop-off.
9. support, bracket use stainless steel material, corrosion-resistant and high-temperature resistant.
In sum, after using said structure of the present utility model, be conducive to controlling the inlet temperature of superheater；Fully profit
By the confined space, at utmost increase heating surface area；Its compact conformation, easy for installation, it is adaptable to the heating surface cloth of multiple boiler
Put.
