Description
Technical field
The present invention relates to a kind of flue gas heat-exchange apparatus, and in particular to it is a kind of can horizontal positioned fluoroplastics pipe type heat transfer
Device, can realize that the tube bank of fluoroplastics flexible pipe is regularly arranged under the conditions of horizontal positioned, eliminate flexible pipe amount of deflection, and the heat exchanger is mainly used in
Flue gas condensing and smoke reutilizer before and after heat-engine plant desulfurized tower, can also be applied to other works based on combustion of fossil fuel
The energy-saving and emission-reduction of industry process.
Background technology
The flue gas of station boiler and other Industrial Boilers generation based on combustion of fossil fuel, waste heat amount is huge, and contains
There is SO2、SO3, the corrosive gas such as HCl, HF, directly discharge not only causes amount of heat to lose, can also trigger acid rain etc. a series of
Environmental problem.Therefore, on heat power plant boiler or other Industrial Boilers, typically it is arranged with flue gas waste heat recovery system
With the smoke reutilizer for avoiding low-temperature corrosion.Flue gas waste heat recovery system is usually to be installed in wet flue gas desulfurization tower porch
Flue gas heat-exchange unit is condensing flue gas.Flue gas can be down to less than 90 DEG C by temperature after heat exchanger, and one side fume afterheat is returned
Receive, on the other hand when flue-gas temperature is down to acid dew point, the sour gas molecule in flue gas can also be condensed liquid reaction, absorb,
SOX、NOX, HCl, HF, the reduction of the concentration of narmful substance such as dust, flue gas heat-exchange unit at this moment is except the work with Mist heat recovering
Beyond, the effect that flue gas is removed in advance has also been taken into account.Smoke re-heater then avoids exhaust gas temperature from dropping by improving flue-gas temperature
As little as acid dew point and cause upstream device and the etching problem and chimney of flue wall to emit white cigarette problem.Therefore, for reality
Existing flue gas waste heat recovery and the double action pre-processed to flue gas, the flue gas for flue gas waste heat recovery and flue gas reheat are changed
Hot device must possess good effect of heat exchange, corrosion-resistant, the features such as be difficult dust stratification.
Fluoroplastics tubular type flue gas heat-exchange unit is the heat transmission equipment in strong corrosive medium developed in recent years, its pipe
Footpath is small, and tube wall is thin, and heat exchange area is big in unit volume, is easy to miniaturization, installs and repairs also very convenient.In addition, its have it is excellent
Good decay resistance, and adhesive capacity is weak, antipollution power is strong, and flexible pipe can vibrate within the specific limits in itself, reach self-cleaning
Effect, thus applied in coal steam-electric plant smoke waste heat recovery and flue gas reheat it is more and more.Because fluorine plastic tube is flexible big, therefore
Vertical disposition is taken existing fluoroplastics pipe heat exchanger more being laminated with avoiding flue gas hose bundle in flowing from bending.But
It is that condensate liquid can flow downward along pipe outer wall when flue gas is condensed in the fluoroplastics pipe heat exchanger being disposed vertically,
Easily accumulation forms liquid film, the heat transfer effect in influence flue gas and pipe between medium.In addition, in the feelings that size of heat exchanger is larger
Under condition, the degree of difficulty of fluoroplastics pipe heat exchanger vertical lifting can also be greatly increased.

U-shaped section of 9 is outer, and its two ends is welded on removable tube sheet 5, outside the fluoroplastics U-tube of internal diameter size and fluoroplastics U-tube beam 9
Footpath size quite, can play restriction and supporting role to fluoroplastics flexible pipe.Front end fixed tube sheet 2-1, positioning orifice plate 3, rear end
Fixed tube sheet 2-2, removable tube sheet 5 and fixed plate 8 are connected by stay bolt 7-1, wherein front end fixed tube sheet 2-1, location hole
Plate 3, rear end fixed tube sheet 2-2 and fixed plate 8 are fixed by equal nut.Removable tube sheet 5 can be moved along stay bolt 7-1.Short spiral shell
Bolt 7-2 one end is welded on removable tube sheet 5, and the other end passes through fixed plate 8.It is rotten to prevent acid gas in flue gas from condensation occurring
Erosion, heat-exchanging tube bundle material therefor is fluorine plastic tube, and fixed tube sheet 2-1 in front end used, rear end fixed tube sheet 2-2 are near flue gas plate face
And the positioning equal outer lining fluoroplastics of orifice plate 3.
A kind of use U-tube beam as shown in Figure 5 can horizontal positioned fluoroplastics pipe heat exchanger overall schematic.In side
When being worked in shape flue, front end fixed tube sheet 2-1 and rear end fixed tube sheet 2-2 equivalent to flue wall, for being tensioned fluoroplastics
The part of tube bank is sealed and placed in outside flue.Flue gas transversal flow fluoroplastics U-tube beam 9, low temperature or high-temperature medium in tube bank
Then from heat transferring medium import hydroecium 1-1 inflow heat exchangers, exchanged heat with flue gas, by entering next fluorine after hemispherical hydroecium
Plastics U-tube beam, most flows out through heat transferring medium outlet hydroecium 1-2 afterwards.Because fluoroplastics tube bank is flexibility, the medium in pipe
Easily bent under Action of Gravity Field and laminated, the positioning orifice plate 3 being evenly arranged along tube bank can to a certain extent ensure that fluorine is moulded
Material flexible pipe is regularly arranged.When flexible pipe tube bank deforms bending, turn lag bolt 7-2 ends nut, so that and fluorine
Plastic tube bundle expanded joint removable tube sheet 5 together is moved along stay bolt 7-1, with tensioning flexible pipe straight length, it is ensured that hose bundle is not
Significantly flexural deformation can occur.Meanwhile, the U-shaped metal tube 10 welded together with removable tube sheet 5 can also be moulded to fluorine
Material U-tube beam 9 produces restriction and supporting role.
