Description
Technical field
The present invention relates to coal fired power plant or thermo-power station flue gas waste heat recovery power-saving technologies.
Background technique
Flue-gas temperature is about 120 ~ 150 DEG C after coal fired power plant air preheater, for the waste heat in recovered flue gas, usually in dedusting
Metallic recuperator is set before device or after deduster.Some power plant are in order to reduce pollutant emission range and chimney be avoided to corrode, also
Equipped with GGH.In terms of operational effect in recent years, metallic recuperator majority occur burn into leakage, dust stratification blocking cause resistance compared with
Big phenomenon runs 2 ~ 3 years and removes can be found everywhere for replacement.
The metal material of heat exchanger is substituted for fluoroplastics, then is a kind of effective alternative solution.Teflon heat exchanger tool
Have the characteristics that zero burn into zero leakage, non-sticky ash make the reduction of power plant's maintenance cost.The teflon heat exchanger service life that foreign countries use earliest
More than 20 years, German most coal-burning power plants are respectively arranged with teflon heat exchanger.Domestic Huaneng Group, state's electricity and Datang group
Multiple power plant have used teflon heat exchanger to substitute original metal GGH, and teflon heat exchanger substitutes metallic recuperator and carries out deeply
Degree waste heat recycling also gradually obtains promotion and application.
Teflon heat exchanger is a kind of indirect heat exchanger, and core component is the tube bank of fluoroplastics heat exchanger tube, and flue gas walks heat exchange
On the outside of pipe, recirculated water is walked on the inside of heat exchanger tube, takes fume afterheat out of recycling by recirculated water.
Fluoroplastics heat exchanger tube general diameter is Φ 14mm, wall thickness 1mm, is fabricated to U-tube tube bank, hangs on top tube sheet
On, the metal framework made of 2205 or 904 materials is fettered outside U-tube beam.Teflon heat exchanger is usually with modular type
Formula factory, and be installed in flue in a manner of module assembled.Suitable for the teflon heat exchanger module of coal fired power plant, top
Tube sheet is normally supported on flue steelframe, and individual module tubesheet dimension is generally 2.5m × 2.5m or 2.5m × 3.5m, height
Generally 10 ~ 13m, single module weight are generally 10 ~ 15t, and the quadrangle of top tube sheet sets that there are four lifting lugs.It is exchanged heat according to fluoroplastics
The size and structure of device module, top lifting are most common mounting means in the mounting means and engineering project of most convenient.
But in Practical Project implementation, to save space occupied, the position of heat exchanger is very compact sometimes, heat exchanger
The neat stress flue that the top of flue may have absorption tower to export needs if using top lifting mode in neat stress flue
The lifting that teflon heat exchanger is completed before installation requires working procedure more harsh；And go out in teflon heat exchanger module
Existing failure when needing to hang out overhaul outside flue, and needs to remove the neat stress flue at top, and human and material resources, mechanical consuming are huge
Greatly.
In view of the above-mentioned problems, we have invented a kind of sides suitable for fluoroplastics flue gas heat-exchange unit to lift construction system.
Summary of the invention
This invention proposed herein, that is, invent a kind of side lifting construction system suitable for fluoroplastics flue gas heat-exchange unit
System.Within the system, using the Steel Structure Installation component reserved in design, and lifting device is used by interim on site, from
Each module installation of fluoroplastics flue gas heat-exchange unit is located in flue by side, it is not necessary to it is limited by the limitation of top installation space, and
It operates conveniently, securely and reliably, substantially increases the installation speed of teflon heat exchanger module.Specific scheme of installation is detailed in attached drawing
1 ~ attached drawing 7.

Bracket is 4..
(3) 4. top surface absolute altitude is higher than Tube Sheet of Heat Exchanger board supporting structure top surface absolute altitude to conversion support, and is higher than in tube sheet fixation
The top surface absolute altitude for the pre- cultivation bolt used.
(4) in the design of the support steel structure of fluoroplastics flue gas heat-exchange unit, in the top of braced frame design lifting purlin
5., crossbeam is arranged according to module number in the upper and lower part of truss to frame, and lower beam is portable beam.
(5) it in the hoisting process of module side, in addition to large-scale crane, needs by means of other interim lifting devices: carrying
With 6. 2, tankette vehicle (load-carrying >=10t/ platform), chain block 7. 4 (load-carrying >=5t/ platform).
(6) lifting program concrete operations in side are as follows: after 8. 1. teflon heat exchanger module being erected by large-scale crane,
Remove transport purlin vehicle；Heat exchanger block supports steel construction piece top temporary weld lifting with temporary track 9.；Utilize crane
8. by module close to lifting with conversion support 4., respectively place a carrying tankette vehicle in the center two sides of conversion support
6. slowly by the bottom of module tube sheet be seated at tankette vehicle 6. on；7. or other tools using chain block, tankette vehicle 6.
