To narrate one embodiment of the present of invention referring to figs. 1 through Fig. 8.
Fig. 1 is the emission-control equipment 1 that explanation is provided, for example emission-control equipment in apparatus for incinerating waste material.(other typical incinerating apparatus comprises: trade waste incinerating apparatus, cinder or cigarette ash melting appartus, TRT and oil refinery equipment) is in emission-control equipment 1, remove cigarette ash from the waste gas that trash burner 2 is discharged and analog and make exhaust gas denitration, be discharged into the atmosphere from chimney 3 then by in waste gas, adding catalyst.
Emission-control equipment 1 comprises: the thermoregulator 11 that is used for the waste gas of discharging from trash burner is cooled to predetermined temperature (about 170 ℃ of the bag dust filter acceptable of for example, narrating below); Be used for from the bag dust filter (dust arrester) 12 of removing dust by thermoregulator 11 waste gas cooled, be used for the waste gas of carrying by waste line 13 from bag dust filter 12 is used the denitrator 14 of predetermined catalyst denitration and the burners that are used for heat exhaust gases (heater) 15 that are provided with in the middle of waste line 13.
Thermoregulator 11 comprises first heat exchanger 21 that is used for the high-temp waste gas of discharging from trash burner by air cooling and is used for by second heat exchanger 22 of high-temp waste gas heating from the waste gas of the lower temperature of bag dust filter 12 outputs.Second heat exchanger 22 is arranged on the upstream of first heat exchanger 21 in the waste gas flow process.
As shown in Figure 2, heat exchanger 21 and 22 is horizontal multi tube heat exchanger (package types), as being flowed by stream of the waste gas as shown in the arrow and air among Fig. 2.
More precisely, high-temp waste gas is input to the housing 22 of second heat exchanger 22 that one side is provided with in the upstream aIn, and be input into the pipeline 22 of second heat exchanger 22 from the waste gas of the lower temperature of bag dust filter 12 output b
The waste gas of exporting from the housing 22a of second heat exchanger 22 is input among the housing 21a of first heat exchanger 21 that is arranged on downstream one side, and the cooling air is input into the pipeline 21 of first heat exchanger 21 b
Shown in the enlarged drawing of Fig. 2, the pipeline 21 of first heat exchanger 21 that contacts with waste gas bThe inner surface of outer surface, housing and tube sheet and other parts be coated with coating 23 (for example fluorocarbon resin coating or ceramic coating), in order to prevent the acid corrosion of dew point.Like this, just can prevent pipeline 21 bOuter surface and the corrosion of similar portions.In this embodiment, the structure of first heat exchanger 21 is in order to make waste gas can flow into housing 21 aInside, this is because the coating of the outer surface of pipeline 21b is easier than the coating of its inner surface.
For preventing the acid corrosion of dew point, particularly will be described the fluorocarbon resin coating of the outer surface of the pipeline 21b that is used for covering first heat exchanger 21 to coating 23.Coating can also be applied to and the tube sheet of contacted first heat exchanger 21 of waste gas and the inner surface of housing and other parts.
More precisely, the method by baking vanish is coated with 200 μ m to the thick preferably 200 μ m of 1000 μ m to the thick PFA resin of 400 μ m (copolymer of tetrafluoroethene and perfluoroalkyl vinyl ethers) at the outer surface of the pipeline 21b of first heat exchanger 21.The typical material of pipeline 21b comprises mild steel and stainless steel.
Be the scope of benchmark and coating layer thickness preferably situation from 200 μ ms to 400 μ ms to use the PFA resin as coating with reference to table 1 explanation.
Table one
The denitration of the antiacid corrosion heat resistance of resin
PFA is fabulous fabulous
FEP is preferable fabulous
PTFE is bad preferable fabulous
PCTFE is fabulous bad fabulous
(25.4mm φ) is coated with various fluorocarbon resin and carries out corrosion resistance test, thermal cycle load test and bend test on steel pipe.Object of reference as fluorocarbon resin is tetrafluoroethene and hexafluoropropylene copolymer (FEP), polytetrafluoroethylene (PTFE) and polytrifluorochloroethylene (PCTFE).Corrosion resistance test is carried out in the most violent use occasion of simulation under the condition of sulfuric acid 80% (under 140 ℃ of temperature) and 20% chloric acid (boiling point).By the thermal cycle load test is carried out in cooling (to 0 ℃) and heating (to 200 ℃) repeatedly.Result of the test is as shown in table 1, and as can be seen from Table 1, the PFA resin all is being fabulous aspect antiacid burn into heat resistance and the denitration.
Secondly, under test temperature lifting and heat conductivility condition, how the thickness of observing the PFA resin in acid dip influences anti-expansion character.In this case, be coated with the PFA resin and test as substrate to have the thick stainless steel of 1.5mm, its result of the test as shown in Figure 5.
As can be seen from Figure 5, the resin-coated thickness of PFA preferably 200 μ m is more preferably 300 μ m to 400 μ m to 400 μ m, and it can be at the needs of not considering to satisfy under the heat conductivility situation anticorrosive and anti-expansion character.
Under the simulated conditions of actual use occasion, carry out corrosion resistance test, in this test, be coated with 200 μ m and stand the dipping of the chloric acid (boiling point) of 80% sulfuric acid (140 ℃) and 20%, and cool off its inner surface by air to steel pipe (25.4mm φ) outer surface of the thick PFA resin of 400 μ m.In addition, carry out thermal cycling test under the simulated conditions of actual use occasion, in this test, the outer surface of steel pipe is cool to room temperature and be heated to 180 ℃ repeatedly, and cools off its inner surface with air.These test announcements have 200 μ m and present fabulous performance to the thick PFA resinous coat of 400 μ m.
It is that method with machinery is coated with steel pipe with the PTFE resin that another kind presents good erosion-resisting typical heat pipe, and still, the PTFE resinous coat has relatively poor adhesion property to steel pipe, and the result causes reducing thermal conductivity and anticorrosive effect.In addition, even the mechanical damage little to the PTFE resinous coat also will cause resin-coated big tearing.In addition, if be subjected to thermal cycle, the PTFE resin also is easy to relax.
To narrate the structure of thermoregulator 11 more accurately with reference to Fig. 3 and Fig. 4.
In thermoregulator 11, the top in framework 31 is provided with second heat exchanger, 22, the first heat exchangers 21 and is divided into two parts 21 that mutual polyphone ground connects AWith 21 B, and be arranged on the bottom of second heat exchanger 22 abreast.If two heat exchangers respectively have identical size, approximately be the twice of second heat exchanger 22 as the second above-mentioned heat exchanger as the length of first heat exchanger, 21, the first heat exchangers 21 so.But in this embodiment, first heat exchanger 21 is divided into the two parts that are arranged on second heat exchanger, 22 bottoms abreast, so that can dwindle the size of adjuster 11.
For example, known emission-control equipment can be handled from trash burner with 4000NM 3The waste gas that the speed of/hr is discharged has 10 except that needing one m(height) * 2.5 mTo the water column type thermoregulator exchange column of 3m (diameter), also need a heat exchanger with 2 * 2 * 5 (height) size.In contrast to this, the thermoregulator according to two heat exchangers 21,22 of present embodiment only accounts for 2.5 m* 1.8 m* 2.5 mThe space of (height).Therefore, with known temperature adjuster exchange column and the heat exchanger specific energy size of dwindling thermoregulator 11 mutually.
The air that has absorbed heat from useless device in first heat exchanger 21 is transported to from the waste gas that denitrator 14 is discharged, and makes the unlikely discharge from chimney 3 as white cigarette of exhaust gas discharged.(definition of so-called herein " white cigarette " is meant and includes steam in waste gas, because of its temperature is lower, so look and be white in color.Because to the influence of environment, the dialogue cigarette takes preventive measures).
From the high-temp waste gas (for example 280 ℃) that trash burner is discharged, flow through second heat exchanger 22 and first heat exchanger 21, so its temperature is lower.For example, calcium hydroxide adds in the waste gas cooled, approximately is 170 ℃ at heat exchanger 22,21 in the way of bag dust filter 12.After utilizing bag dust filter 12 to remove cigarette ash from waste gas, waste gas heats in second heat exchanger 22.After this, waste gas heats again, for example is heated to about 230 ℃ by being arranged on waste line 13 middle heaters 15, and is transported to denitrator 14 catalytic denitrations.
In order to prevent the generation of white cigarette, the air by the cooling exhaust heat absorption in first heat exchanger 21 is transported to from the waste gas that denitrator 14 is discharged, and waste gas is discharged from chimney 3 then.
The waste gas of discharging from bag dust filter 12 from the heat handle of the waste gas of trash burner discharge by the second heat exchanger utilization is heated to the temperature required catalytic denitration that is used for.Therefore, emission-control equipment of the present invention than adopt the common emission-control equipment economy only utilize a cooling exhaust of heater heating many.
In addition, because thermoregulator 11 has two heat exchangers 21,22 that are provided with vertically therein, a heat exchanger 21 is divided into the two parts that are arranged in parallel, and is parallel to another heat exchanger 22, so the size of thermoregulator 11 can be dwindled widely.
In the above-described embodiments, though first heat exchanger is divided into the two parts that are arranged on the second heat exchanger bottom abreast, two parts 21 of first heat exchanger 21 AWith 21 BCan be arranged on the top of second heat exchanger abreast, as shown in Figure 6, perhaps two parts 21 AWith 21 BCan be parallel to each other and be arranged on a side of 22 of second heat exchanger vertically, as shown in Figure 7.
In addition, though the foregoing description adopts is the housing 22 that high-temp waste gas is transported to second heat exchanger 22 aBut high-temp waste gas also can be transported to the pipeline 22 of second heat exchanger 22 b, as shown in Figure 8.Yet, be the dust of removing on the inner surface of second heat exchanger 22, the cigarette ash that for example in waste gas, adheres to, structure as shown in Figure 2 makes and is flowing in pipeline 22 bThe waste gas of outside can be easy to clear operation.
In addition, in the above-described embodiments, though be used in the middle of the waste line 13 of direct exhaust from second heat exchanger to denitrator burner (heater) being set, burner can not necessarily need.
Although narrated the present invention above, must understand and to make all changes and not exceed scope of the present invention the present invention by specific embodiments of the invention.
