Description

The waste gas purification facility of heating power
Technical field
The present invention relates to the waste gas purification facility of heating power; The waste gas purification facility of this heating power comprises that combustion chamber and the heat that is used for the pure qi (oxygen) body that comfortable combustion chamber in the future produces pass to the heat exchanger of the thick gas of waiting to flow to combustion chamber; Wherein, heat exchanger comprise by fluid media (medium) can percolation interior heat exchanger space and by outside fluid media (medium) can percolation heat exchanger space outside.
Background technology
The pure qi (oxygen) body of being discharged by the waste gas purification facility of this heating power is normally used for other thermodynamic process, so when the waste gas purification facility of heating power is discharged, must regulate pure qi (oxygen) body discharge temperature.
In order to regulate pure qi (oxygen) body discharge temperature, use inner hot gas bypass flap according to prior art.Realize making very hot pure qi (oxygen) body directly to export the pure qi (oxygen) body of discharging through the pure qi (oxygen) body-thick gas heat exchanger of the inside of the waste gas purification facility of heating power and the pure qi (oxygen) body of directly being sneaked into through opening or partially open this valve by pure qi (oxygen) body-thick gas heat exchanger by the combustion chamber guiding.Mixed flow by directly constituting from the pure qi (oxygen) body of the heat of combustion chamber and the pure qi (oxygen) body that in pure qi (oxygen) body-thick gas heat exchanger, cools off reaches a mixing temperature then, and this mixing temperature is corresponding to desired pure qi (oxygen) body discharge temperature.
But in the waste gas purification facility with the heating power of the make of compactness, this hot gas bypass flap structure type is arranged on the end of combustion chamber and on the beginning of the reaction chamber of the waste gas percolation in origin spontaneous combustion chamber under the situation of the bypass flap of closing with causing.
Thus, waste gas to be cleaned was extended in the time of staying that transforms fully on the required reaction temperature for the harmful substance that will comprise within it.
In order fully to finish all conversion reactions, necessary is to keep the sufficiently long time of staying, this time of staying as far as the waste gas purification facility of each heating power be fix and usually between 0.8 second and 1.2 seconds.In the case, refer to stop duration of the gas molecule in so-called reaction compartment as the time of staying, reaction compartment is formed by combustion chamber with around the reaction chamber of combustion chamber.The time of staying is accompanied by thick gas and begins through burner entering combustion chamber and be accompanied by in pure qi (oxygen) body entering pure qi (oxygen) body-thick gas heat exchanger to finish, and the pure qi (oxygen) body passes through to the heat transmission of thick gas and is cooled in pure qi (oxygen) body-thick gas heat exchanger.
When taking out the shunting of waste gas through the hot gas bypass flap now, reaction chamber is no longer flow through in this shunting, but after combustion chamber, just leaves reaction compartment.Shortened the time of staying to this shunting of waste gas thus, and cannot in this shunting, finish whole conversion reactions, these conversion reactions are essential as far as harmful substance elimination completely.
The article qualitative change of the pure qi (oxygen) body of being discharged by the waste gas purification facility of heating power thus, is poor.
Be to the known means to save the situation of this problem, other turn-around chamber inserted in the reaction compartment that this turn-around chamber part has at least compensated the shortening to the time of staying of the waste gas shunting of taking out through the hot gas bypass flap.But the defective of this turn-around chamber is that this turn-around chamber structure type has reduced the time of staying of the shunting of taking out to obstructed overheated gas bypass flap with causing.In order to compensate the minimizing of the time of staying, the waste gas purification facility of heating power must be constructed longlyer and on volume, become big, and this has improved the space requirement of the waste gas purification facility of heating power.
Summary of the invention
Therefore the present invention is based on following task, that is, accomplish the waste gas purification facility of the heating power of the mentioned type of beginning, it makes that the adjusting to pure qi (oxygen) body discharge temperature becomes possibility under the situation that does not reduce pure qi (oxygen) body quality.

The present invention is based on such conception; Promptly; Regulate the pure qi (oxygen) body discharge temperature of the waste gas purification facility of heating power through following mode; That is, the part of fluid stream outside gets around a section of the pure qi (oxygen) body-thick gas heat exchanger of the waste gas purification facility of heating power, can reduce efficiency of heat exchanger with affined mode thus.
At this, fluid stream outside can relate to thick gas that flows to heat exchanger or the pure qi (oxygen) body that flows to heat exchanger.
Opposite with the use of hot gas bypass flap is that this division that the time of staying on the reaction temperature of waste gas in reaction compartment under any circumstance can not flow owing to fluid outside is shortened.
Pure qi (oxygen) body discharge temperature TA can be by regulating through following mode by pure qi (oxygen) body-thick gas heat exchanger that the present invention regulates simply, that is, the share that bypass flow stream accounts for total fluid stream outside is changed.
The share that bypass flow stream accounts for total fluid stream outside is big more, and the efficient of pure qi (oxygen) body-thick gas heat exchanger is just low more and therefore the pure qi (oxygen) body discharge temperature in the pure qi (oxygen) body outlet of the waste gas purification facility of heating power is just high more.
In preferred design of the present invention, be provided with, bypass flow stream comprises that by its equipment of sneaking in the residual fluid stream of sneaking into again at least one sneaks into the position, and this is sneaked into the position and on the periphery of the flow path of residual fluid stream half at least, extends.Realize that in this way cold bypass flow flows to as far as possible sneaking into uniformly in the residual fluid stream that in the section of the process in outside heat exchanger space, has heated.
Particularly advantageously be, the equipment of sneaking into comprises that at least one sneaks into the position, this sneak into the position the periphery of residual fluid stream 2/3 on, especially at least 90%, extend.
Particularly advantageous is that this is sneaked into the position and on the whole periphery of residual fluid stream, extends basically.
In preferred design of the present invention, be provided with, this is sneaked into the position and around the flow path of residual fluid stream, extends ringwise.
Through sneaking into the very good mixing that has realized two stocks streams in other words should a big chunk of periphery on the whole periphery of residual fluid stream without pre-warmed bypass flow stream.
Avoided the defective that under the situation of only sneaking into, obtains thus through the pipeline part, that is, heating power unbalance and the heating power stress in the zone of facility shell that causes thus, these heating power stress are to influence the service life of waste gas purification facility negatively.
When two stocks stream has very different viscosity based on different temperature, so the sneaking on a big chunk of the periphery that residual fluid flows that flows in the residual fluid stream through bypass flow also adjusts the uniform mixing that two stocks flow.
Improve the thermodynamic behaviour of waste gas purification facility through the high uniformity that flows the total fluid stream that mixes by bypass flow stream and residual fluid.
Alternative or be complemented at the position of sneaking into of on the periphery of residual fluid stream half at least, extending; Sneak into equipment and also can comprise a plurality of positions of sneaking into; Wherein, these are sneaked into site distribution and are sneaking on the zone, and this is sneaked into the zone and on the periphery of residual fluid stream half at least, extends.
Particularly advantageously be, sneak into the zone the periphery of residual fluid stream 2/3, preferably at least 90% on extend.
In the preferred design of waste gas purification facility, sneak into the zone and on the whole periphery of residual fluid stream, extend basically.
Bypass flow stream mixes preferably at least in part, especially mainly in the blending space of the Tube Sheet of Heat Exchanger that does not comprise heat exchanger, carries out with residual fluid stream.Avoided cold bypass flow stream directly to load Tube Sheet of Heat Exchanger thus, this can cause very high heating power stress.
Blending space especially can be outside the heat exchanger tube of radial arrangement at heat exchanger.
By-pass collar can comprise following bypass passageways, the flow path that this bypass passageways flows around residual fluid ringwise.
Through this bypass passageways, bypass flow stream arrives the equipment of sneaking into by separation equipment.
Bypass passageways preferably on the part of heat exchanger length, preferably heat exchanger length 1/3 on, especially on heat exchanger length half at least, extend.
For the distribution that the homogenising bypass flow stream of trying one's best surmounts the entire cross section of bypass passageways through bypass passageways, by-pass collar preferably comprises at least one restricting element in the flow path of bypass flow stream.
This restricting element can especially be configured to the flow obstacle with a plurality of through holes.
Bypass passageways can be open tubular column bodily form ground structure especially basically.
When a plurality of through holes in the fluid obstacle totally through face be by-pass collar the entering cross section 150% or still less, especially 125% or still less the time, realized of pass through especially good distribution cross section on of bypass flow stream in bypass passageways.
In order not improve the flow resistance of restricting element too consumingly, in addition advantageously, a plurality of through holes of circulation in the obstacle totally through face be by-pass collar the entering cross section 50% or more, especially 75% or more.
In preferred design of the present invention, be provided with, sneak into apparatus arrangement flows out the outlet in heat exchanger space outside at fluid media (medium) outside the upper reaches.Also carry out bypass flow thus and flow to sneaking in the residual fluid stream in pure qi (oxygen) body-thick gas heat exchanger inside; Realized thus outside fluid stream before heat exchanger flows out (that is during fluid outside thick gas is used as to combustion chamber; Or during the fluid outside the pure qi (oxygen) body is used as in pure qi (oxygen) body pipeline), two stocks stream is mixed well each other.
In order to control or regulate the pure qi (oxygen) body discharge temperature of the waste gas purification facility of heating power with simple mode; Advantageously, separation equipment comprises that being used for controlling bypass flow flows into the bypass flap of by-pass collar and be used for controlling the heat exchanger valve that residual fluid flows into heat exchanger.
Preferably, bypass flap and heat exchanger valve ground mechanically and/or on the control technology (that is to say through the coordination by the control appliance of the waste gas purification facility of heating power and control) is coupled to each other in the case.
This connection for example realizes through suitable valve mechanism.
The preferred connection of carrying out two valve like this; Promptly; Bypass flap open motion side by side along with the closing movement of heat exchanger valve carries out, vice versa, wherein; The entering cross section of by-pass collar is become big through the motion of opening of bypass flap, and the entering cross section in the heat exchanger is diminished through the closing movement of heat exchanger valve.
Through the connection of bypass flap and heat exchanger valve, can preferably whole fluid stream outside be divided into bypass flow stream and residual fluid stream basically steplessly, can regulate efficiency of heat exchanger and then pure qi (oxygen) body discharge temperature with simple mode thus.
The separation equipment preferred arrangements flows to the upper reaches of the inlet in the heat exchanger space outside at residual fluid.Thus before residual fluid flows in the heat exchanger and in this heat exchanger, is heated or cooled, outside fluid stream is divided into bypass flow stream flows with residual fluid.In the special design by the waste gas purification facility of heating power of the present invention, be provided with, heat exchanger space outside can be by the thick gas percolation of waiting to flow to combustion chamber.In this case, thick gas is used as outer fluid.
Alternatively also can be provided with this, heat exchanger space outside can be by the pure qi (oxygen) body percolation that in combustion chamber, produces.The pure qi (oxygen) body is used as outer fluid in this case.
The present invention relates to the method that is used for purifying by the waste gas purification facility of heating power the thick gas stream that comprises oxidable component in addition, and this method comprises following method step:
-thick gas stream is flowed to combustion chamber;
-produce pure qi (oxygen) body stream through the partial oxidation at least of the oxidable component of thick gas stream in combustion chamber;
-in the future the heat of self-cleaning gas stream passes to thick gas stream by heat exchanger, wherein, heat exchanger comprise by the fluid media (medium) percolation in interior heat exchanger space with by the heat exchanger space outside of outside fluid media (medium) percolation.
The present invention is based on other task as follows, that is, create the method for aforementioned type, this method makes the adjusting of pure qi (oxygen) body discharge temperature become possibility, and can not damage the quality of pure qi (oxygen) body.
This task solves according to the characteristic of the preamble of the present invention through having claim 15, and this method comprises following other method step:
-by separation equipment will be outside a part and outside the residual fluid flow point of fluid stream from flowing as bypass flow; And
-behind residual fluid stream a section, bypass flow stream is sneaked in the residual fluid stream by the equipment of sneaking into through outside heat exchanger space.
Become the waste gas purification facility of backflow heat exchange type by the waste gas purification facility preferable configuration of heating power of the present invention, have the pure qi (oxygen) body-thick gas heat exchanger of backflow heat exchange type.
Because utilizing through the adjustable heat exchanger that in waste gas purification facility, uses under the situation of by-pass collar and can improve pure qi (oxygen) body discharge temperature when needed by heating power of the present invention; Meaningfully; With the operating point of the waste gas purification facility of heating power is not to be designed on the specified discharge temperature of pure qi (oxygen) body, but be designed on the lower slightly temperature, preferably on low at least 10 ℃ temperature, especially on low about 20 ℃ temperature.
So during the waste gas purification facility operation of heating power, can regulate actual required pure qi (oxygen) body discharge temperature TA by the adjusting of bypass flap and heat exchanger valve through heat exchanger.
In the stage that the less heat by the heat exchanger of the waste gas purification facility that is placed on heating power descends, then for example can be adjusted on the low pure qi (oxygen) body discharge temperature of trying one's best of operating point in suspending producing, so that save energy.
In all adjusting positions of heat exchanger, the whole time of staying of waste gas in reaction compartment keeps ground to obtain.
In by the waste gas purification facility of heating power of the present invention, can not use hot gas bypass flap ground to regulate pure qi (oxygen) body discharge temperature.
Therefore also can cancel this hot gas bypass flap, the pure qi (oxygen) body of heat directly arrives the pure qi (oxygen) body outlet of waste gas purification facility from combustion chamber through this hot gas bypass flap.
For the pure qi (oxygen) body discharge temperature of the waste gas purification facility that under the situation of needs, can further improve heating power, except by-pass collar, also can be provided with such hot gas bypass flap by the waste gas purification facility of heating power of the present invention.
Waste gas to be clean in combustion chamber with in the reaction chamber of then combustion chamber or the time of staying in the pure qi (oxygen) body passage of then combustion chamber do not rely on by-pass collar adjusting position remain identically.
The primary energy demand of the waste gas purification facility of heating power obviously reduces at the quilt in service that pauses.
Especially realize that around the arranged concentric of heat exchanger and through flowing bypass flow flows to sneaking into uniformly of residual fluid stream in the heat exchanger through by-pass collar by the bypass flow of restricting element homogenising through by-pass collar.
The optimum efficiency and the even temperature in the waste gas purification facility of heating power that have realized heat exchanger thus distribute, and this is to improving the particular importance in service life of waste gas purification facility.
When thick gas formed outside the fluid stream that is divided into bypass flow stream and residual fluid stream, this two stocks stream by mixing each other equably, was realized the stable purification efficiency of waste gas purification facility thus before thick gas gets into burner so.
Bypass flow stream on a big chunk of the periphery of residual fluid stream, preferred evenly sneaking on whole periphery, will drop to minimum degree by the heating power stress that thermograde causes.
When the waste gas purification facility of heating power designs in this wise; Thereby when the design temperature in the operating point of the waste gas purification facility of heating power is lower than the specified discharge temperature of pure qi (oxygen) body; By the heat exchanger that can regulate; Actual pure qi (oxygen) body discharge temperature in the waste gas purification facility operation of heating power both can be adjusted on the temperature that is higher than specified discharge temperature, can be adjusted on the temperature that is lower than specified discharge temperature again.

Waste gas to be cleaned is mist, and it contains oxidable component, for example volatile organic compound.
The oxidable component of waste gas is oxidized and then become harmless in combustion chamber 102 together with the fuel that adds.
Flow to mist combustion chamber 102, that comprise the incendivity component and next be called as thick gas.
Next the mist that oxidation produced of the oxidable component through thick gas in combustion chamber 102 is called as the pure qi (oxygen) body.
Thick gas is from pure thick gas source that schematically show and that mark with Reference numeral 114 among Fig. 1.
The thick gas volume flow of being carried by the runic gas source 114 of the waste gas purification facility 100 of heating power preferably is at least 1000Nm 3/ h (1Nm 3=1 standard cubic meter), 10000Nm especially at least 3/ h.
Flow to the thick gas access 116 of the waste gas purification facility 100 of heating power through thick gas transfer pipeline 118 from the thick gas of runic gas source 114; Thick gas fan 120 is arranged in this thick gas transfer pipeline, and thick gas fan pushes from thick gas source 114 thick gas to combustion chamber 102.
In addition, thick gas transfer pipeline 118 can be provided with differential manometer 122, thick gas fan 120 on the pressure side and the pressure differential deltap p between the suction side can know by this differential manometer.
Arranged downstream in the thick gas access 116 in the waste gas purification facility 100 of heating power has the separation equipment 124 of by-pass collar 126; The part of thick gas stream can leave by the residual fluid flow point of this separation equipment with thick gas as bypass flow stream, and can flow to the bypass passageways 130 of by-pass collar 126 through bypass opening 128.
Residual fluid stream gets into the secondary side of the pure qi (oxygen) body-thick gas heat exchanger 134 of backflow heat exchange types through thick gas access 132, this pure qi (oxygen) body-thick gas heat exchanger at primary side by pure qi (oxygen) body percolation from the combustion chamber effusion.

These rearmounted heat exchangers especially can be used be used for that steam produces, the deep fat heating, hot water produces or warm water produces or be used and be used for circulating air heating or fresh air heating.
The waste gas purification facility 100 of heating power can comprise differential manometer 166, can be informed in the pressure differential deltap p between pure qi (oxygen) body pipeline 164 and the thick gas access 116 in the waste gas purification facility 100 of heating power by this differential manometer.
Can divide expenditure bypass line 170 from reaction chamber or with the pure qi (oxygen) body passage 168 that the pure qi (oxygen) body outlet 158 of the pure qi (oxygen) body inlet 160 of pure qi (oxygen) body-thick gas heat exchanger 134 and combustion chamber 102 couples together, this bypass line feeds in the pure qi (oxygen) body pipeline 164 in the downstream of the pure qi (oxygen) body outlet 162 of pure qi (oxygen) body-thick gas heat exchanger 134.
Getting around through this at least a portion under the situation of pure qi (oxygen) body-thick gas heat exchanger 134 and directly flowing to the rearmounted in other words heat exchanger of waste stack, especially when to one of them heat demand of the heat exchanger of postposition when high especially at the pure qi (oxygen) body in the bypass line 170 of hot side spontaneous combustion in the future chamber 102.
Bypass flow through at the bypass line 170 of hot side can be by being arranged in bypass flap 172 controls in the bypass line 170 or regulating.
In Fig. 2, show in detail combustion chamber 102 and the pure qi (oxygen) body that is connected with this combustion chamber-thick gas heat exchanger 134 by the waste gas purification facility 100 of the heating power that has by-pass collar 126 of Fig. 1.
Can see that by Fig. 2 combustion chamber 102 is configured to be basically cylinder shape, along central longitudinal axis 174 from extending in distolateral 176 of burner side until deviating from the distolateral 178 of burner 104, and by combustion chamber wall 180 boundaries that are the open tubular column bodily form.
Combustion chamber 104 is centered on by the pure qi (oxygen) body that in this form of implementation, is configured to be basically the open tubular column bodily form-thick gas heat exchanger 134, and this pure qi (oxygen) body-thick gas heat exchanger deviates from the radial outside of combustion chamber 104 by outer cover of heat exchanger body 182 boundaries that are cylinder shape and at it at it and faces on the radially inner side of combustion chamber 102 by heat exchanger inner housing 184 boundaries that are cylinder shape equally basically.
Outer cover of heat exchanger body 182 has formed heat exchanger shell 142 jointly with heat exchanger inner housing 184, the heat exchanger shell boundary heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134.
Heat exchanger inner housing 184 is supported on the combustion chamber wall 180 through support ring 186.
Form pure qi (oxygen) body passage 168 by the intermediate space between combustion chamber wall 180 and heat exchanger inner housing 184, this pure qi (oxygen) body passage couples together with pure qi (oxygen) body-thick gas heat exchanger 134 distolateral 178 of the burner that deviates from of combustion chamber 102 with the pure qi (oxygen) body inlet 160 in distolateral 176 arranged adjacent of burner side combustion chamber 102.
Arranging the heat exchanger tube 136 that constitutes by a large amount of Tube Sheet of Heat Exchanger 138 in the intermediate space between heat exchanger inner housing 184 and outer cover of heat exchanger body 182.
Tube Sheet of Heat Exchanger 138 all is arranged essentially parallel to longitudinal axis 174 and distributes and formed one or more, two Tube Sheet of Heat Exchanger layers 188 that are cylinder shape for example, Tube Sheet of Heat Exchanger 138 each with apart from the identical radial spacing of longitudinal axis 174 and along periphery basically equidistance be arranged in distributively in these Tube Sheet of Heat Exchanger layers.
Each Tube Sheet of Heat Exchanger 138 remains on a plurality of that follow in succession before and after on the direction of longitudinal axis 174 and preferred basically each other on the holding element 190 of equidistant placement, and these holding elements for example are configured to be basically the retention tab 192 of annular.
Tube Sheet of Heat Exchanger 138 is applied in the through hole in the holding element and abuts in hermetically on the holding element 190 with its outside 194 fluids, thereby makes that do not have fluid basically runs through to get into through holding element 190 and be in the zone outside the Tube Sheet of Heat Exchanger 138.
On two ends of Tube Sheet of Heat Exchanger 138, holding element 190 materials of these Tube Sheet of Heat Exchanger 138 and each are connected sealedly, for example welding.
On the direction of longitudinal axis 174, have less inside radius and bigger outer radius interior holding element 190a with have holding element 190b outside alternately to follow in succession front and back than at bigger outer radius of interior holding element 190a and bigger inside radius.
Have basically the corresponding inside radius of outer radius with the peripheral wall of heat exchanger inner housing 184 at interior holding element 190a, thereby make and do not have fluid basically in radially process between interior edge and heat exchanger inner housing 184 at interior holding element 190a.
Be supported on the heat exchanger inner housing 183 with piston shoes 196 at interior holding element 190a; But not to be connected with heat exchanger inner housing 183 firmly; Thereby make interior holding element 190a for equilibrium based on thermograde or based on the difference of the coefficient of expansion of heating power and different thermal expansions can move on the direction of longitudinal axis 174 relative to heat exchanger inner housing 184.
Only be slightly larger than the outer radius of heat exchanger tube 136 in the outer radius of interior holding element 190a; Thereby make between opposite side, remain with in the inboard of the edge outside of interior holding element 190a 198 1 sides and outer cover of heat exchanger body 182 outside pass through gap 200a, fluid can pass through this outside pass through the gap.
The outer radius of holding element 190b outside is basically corresponding to the radius of the inboard of the peripheral wall of outer cover of heat exchanger body 182, thus make outside holding element 190b abut on the inboard of outer cover of heat exchanger body 182 with its edge outside and do not have basically fluid can be between outside holding element 190b and outer cover of heat exchanger body 182 process.
The inside radius of holding element 190a outside only is slightly less than the inside radius of heat exchanger tube 136; Thereby make that fluid can pass this in the interior gap of passing through between interior edge 202 and heat exchanger inner housing 184, the remaining with at the interior gap 200b that passes through of outside holding element 190b.
Thus longitudinal axis 174 stagger relative to each other in the radial direction formed the division that is labyrinth shape in the heat exchanger space 144 outside of mechanically transfer and pure qi (oxygen) body-thick gas heat exchanger 134 at interior holding element 190a and holding element 190b outside, thereby make and in heat exchanger space 144 outside, be configured with cranky flow path to fluid media (medium).
Gas heat exchanger is in service comes percolation by the thick gas of treating preheating at this pure qi (oxygen) body-thick in this heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134, and this thick gas of treating preheating is used as fluid media (medium) outside in this form of implementation.
Give thick gas because force cranky flow path,, in these Tube Sheet of Heat Exchanger, flow most of longitudinal direction so thick gas streams Tube Sheet of Heat Exchanger 138 transverse to Tube Sheet of Heat Exchanger 138 as pure qi (oxygen) body at interior fluid media (medium) through holding element 190.
Because in addition the mean flow direction of pure qi (oxygen) body in Tube Sheet of Heat Exchanger 138 from the burner side distolateral 176 to deviate from burner distolateral 178 the orientation; And the mean flow direction of thick gas then along the flow path in heat exchanger space 144 outside basically with the flow direction 204 antiparallels ground orientation of pure qi (oxygen) body through Tube Sheet of Heat Exchanger 138, so pure qi (oxygen) body-thick gas heat exchanger 134 in this form of implementation basically according to the cross-counterflow principle work.
Thick gas gets into pure qi (oxygen) body-thick gas heat exchanger 134 to carry out through the separation equipment 124 being stretched out by outer cover of heat exchanger body 182 in the radial direction of by-pass collar 126, this separation equipment be arranged on the end that deviates from burner 104 of pure qi (oxygen) body-thick gas heat exchanger 134 and preferred arrangements pure qi (oxygen) body-thick gas heat exchanger on last summit (Kuppe).
Separation equipment 124 comprises entering hoistway 206; This gets into hoistway and is connected with thick gas transfer pipeline 118 at the upper reaches, in downstream then on thick gas access 132 in the heat exchanger space 144 outside of the gas heat exchanger 134 of remittance pure qi (oxygen) body-slightly and can completely or partially seal by heat exchanger valve 208.
Separation equipment 124 comprises bypass hoistway 210 in addition, and this bypass hoistway is same at the upper reaches to be connected with gas transfer pipeline 118 slightly, then imports in the bypass passageways 130 of by-pass collar 126 in downstream and can completely or partially seal by bypass flap 212.
The bypass flap in bypass hoistway 210 212 of pure qi (oxygen) body-thick gas heat exchanger 134 and the heat exchanger valve in getting into hoistway 206 ground mechanically and/or on the control technology (that is to say by the coordination of the control appliance of the waste gas purification facility 100 that passes through heating power of valve and control) is coupled to each other in this wise; That is, they are opened in other words on the contrary all the time and are closed.
In bypass flap 212 is brought to like upper/lower positions; Bypass flap discharges when being used for the bigger entering cross section of thick gas through bypass hoistway 210 in this position; The motion of the heat exchanger valve 208 that connects through the motion with bypass flap 212 so side by side takes heat exchanger valve 208 as in the upper/lower positions to; The heat exchanger valve has correspondingly reduced to be used for the entering cross section of thick gas through entering hoistway 206 in this position, and vice versa.
The manipulation of the connection through bypass flap 212 and heat exchanger valve 208 thus can be divided into through the bypass flow stream of bypass flap 212 with through the residual fluid stream of heat exchanger valve 208 with every kind of desired ratio from the thick gas stream of thick gas source 114.
At this, preferred bypass flow stream accounts for the volume share (measuring with standard cubic meter) of the whole thick gas stream of having carried can be especially basically steplessly, at least in about 20% to 80% scope inner control or adjusting.
Bypass passageways 130 is configured to be the open tubular column bodily form basically and centers on pure qi (oxygen) body-thick gas heat exchanger 134 ringwise in this form of implementation of the waste gas purification facility 100 of heating power section.
Bypass passageways 130 faces on the radially inner side of pure qi (oxygen) body-thick gas heat exchanger 134 through outer cover of heat exchanger body 182 and at it at it and deviates from the radial outside of pure qi (oxygen) body-thick gas heat exchanger 134 through being bypass shell body 214 boundaries of cylinder shape.
Bypass passageways 130 flows the bypass hoistway 210 that imports bypass passageways 130 along longitudinal axis 174 from bypass flow; The part of the length of process pure qi (oxygen) body-thick gas heat exchanger 134; Preferably pass through pure qi (oxygen) body-thick gas heat exchanger 134 length 1/3; Extension is until the equipment of sneaking into 148 of by-pass collar 126, and bypass flow stream is sneaked into the residual fluid stream of being sneaked into again in the equipment in heat exchanger space 144 outside at this.
Sneaking into equipment 148 comprises: bypass passageways end wall 216, this bypass passageways end wall are the bypass passageways 130 of the open tubular column bodily form in distolateral sealing; And the ringwise gap 218 of passing through in outer cover of heat exchanger body 182, can be from the bypass flow stream of the bypass passageways that is the open tubular column bodily form 130 through this heat exchanger space 144 outside that is the open tubular column bodily form equally through gap entering pure qi (oxygen) body-thick gas heat exchanger 134.
Formed thus through gap 218 and to have sneaked into position 220, this is sneaked into the whole periphery of flow path of crossing the whole periphery in heat exchanger space 144 outside and crossing the residual fluid stream in percolation heat exchanger space 144 outside thus in the position and extends.
For the try one's best distribution of the bypass flow stream of homogenising through bypass passageways 130 of the whole periphery of crossing the bypass passageways 130 that is the open tubular column bodily form; In bypass passageways 130 at separation equipment 124 with sneak into and be provided with one or more restricting elements 222 between the equipment 148; Wherein, Bypass flow stream only gets into bypass passageways 130 through bypass hoistway 210 on the upside of bypass passageways 130; Restricting element respectively is configured to flow obstacle, its have preferably be equally spaced basically along the periphery of restricting element 222, be used for a plurality of through holes 224 of bypass flow stream through restricting element 222.
At this, a plurality of through holes 224 in this flow obstacle totally through face preferably account for maximum entering cross section that bypass flap 212 discharges in bypass hoistway 210 150% or still less.
Especially can be provided with, in this flow obstacle a plurality of through holes 224 totally through face account for maximum that bypass flap 212 discharges in bypass hoistway 210 pass through cross section 125% or still less, for example about 100%.
In addition, a plurality of through holes 224 in this flow obstacle totally through face preferably account for maximum entering cross section that bypass flap 212 discharges in bypass hoistway 210 about 50%, especially at least about 75%.
Restricting element 222 can especially be configured to the throttling sheet with through hole 224, this throttling sheet can be integrally with outside holding element 190b in each formal construction with retention tab 192.
From the discharge of total fluid stream of joining together once again by bypass flow stream and residual fluid stream of the thick gas in the heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134 pure qi (oxygen) body-thick gas heat exchanger 134 on the end of burner side in the thick air accumulation space 226 carry out, this thick air accumulation space is in during the fluid of the thick gas access 132 of burner 104 is connected.
The pure qi (oxygen) body from pure qi (oxygen) body-thick gas heat exchanger 134 interior heat exchanger space 140 be discharged to that ground carries out in the end that deviates from burner 104 of pure qi (oxygen) body-thick gas heat exchanger 134 the pure qi (oxygen) body accumulation chamber 228, the end that is in pure qi (oxygen) body downstream of Tube Sheet of Heat Exchanger 138 feeds in this pure qi (oxygen) body accumulation chamber.
Beginning pure qi (oxygen) body pipeline 164 on pure qi (oxygen) body accumulation chamber 228, the pure qi (oxygen) body passes through this pure qi (oxygen) body pipeline to rearmounted in case of necessity heat exchanger and mobile to waste stack at last.
Additional pure qi (oxygen) body can be through the bypass line 170 in hot side of its guiding through the primary side of pure qi (oxygen) body-thick gas heat exchanger 134; In this form of implementation, formed by so-called condenser 230, the end that deviates from burner 104 and the opposite side that this condenser for example has the shape of hollow cylinder and is in a side and combustion chamber 102 is with during the fluid of pure qi (oxygen) body accumulation chamber 228 is connected.
This external condenser 230; For example on the end of its accumulation chamber side, be provided with bypass flap 172; This bypass flap can make adjustment become possibility from the share of the pure qi (oxygen) body stream of combustion chamber 102; The share of this pure qi (oxygen) body stream directly gets into the pure qi (oxygen) body accumulation chamber 228 from combustion chamber 102, and needn't pass through pure qi (oxygen) body-thick gas heat exchanger 134 earlier.
In order to improve the effect of in pure qi (oxygen) body-thick gas heat exchanger 134, transmitting to the heat of thick gas from the pure qi (oxygen) body, Tube Sheet of Heat Exchanger 138 can be provided with the surface texture of turbulization on the inboard of its wall and the outside.
Especially can be provided with at this, Tube Sheet of Heat Exchanger 138 is configured to cyclone pipe (Drallrohre).
This cyclone pipe is for example in DIN 28178 (in the text in May, 2009) explanation.
But Tube Sheet of Heat Exchanger 138 also can be configured to plain tube.
Shown in Fig. 1 and Fig. 2 and the form of implementation of the waste gas purification facility 100 of the heating power that emphasizes operate as follows:
Thick gas from thick gas source 114 arrives the separation equipment 124 of by-pass collar 126 and is divided into the residual fluid stream in bypass flow stream that gets in the bypass passageways 130 and the heat exchanger space 144 outside that directly gets into pure qi (oxygen) body-thick gas heat exchanger 134 there.
The volume share that bypass flow stream and residual fluid stream account for total thick gas stream depends on each location through adjustment of bypass flap 212 and heat exchanger valve 208 at this.
The share of bypass flow stream is big more, and the efficient of pure qi (oxygen) body-thick gas heat exchanger 134 is just low more, and discharge temperature T AJust high more, the pure qi (oxygen) body follows this discharge temperature to discharge from pure qi (oxygen) body-thick gas heat exchanger 134.
The discharge temperature of pure qi (oxygen) body can be adjusted according to the difference of the desired pure qi (oxygen) temperature on the heat exchanger of postposition by adjustable pure qi (oxygen) body-thick gas heat exchanger 134 thus.
In the bypass line 170 of bypass flap 172, be opened, thereby when making pure qi (oxygen) body from combustion chamber 102 can directly get in the pure qi (oxygen) body pipeline 164, can realize the further raising of the discharge temperature of pure qi (oxygen) body in hot side.But shortened the reaction time of the incendivity component oxidation that is provided for thick gas, do not passed pure qi (oxygen) body passage 168 because get into the pure qi (oxygen) body of bypass line 170 through the bypass line 170 that is utilized in hot side.
Bypass flow stream flows to residual fluid stream again very equably by the equipment of sneaking into 148; Because bypass passageways 130 is implemented as hollow cylinder; This hollow cylinder arranges around pure qi (oxygen) body-thick gas heat exchanger 134 with one heart, and extends on the whole periphery of sneaking into 201 places, position in outside heat exchanger space 144 because of sneaking into position 220.
In addition, the restricting element 222 that is arranged in the bypass passageways 130 works as stopping up level, and these stop up the distribution of level homogenising bypass flow stream on the periphery of bypass passageways 130.
Total fluid stream of being joined together once again by bypass flow stream and residual fluid stream of thick gas passes through gap 200a, 200b along cranky flow path and in cross-counterflow, flows to the thick air accumulation space 226 on the end of burner side of gas heat exchanger 134 of pure qi (oxygen) body-slightly along Tube Sheet of Heat Exchanger 138 and against the flow direction 204 of pure qi (oxygen) body.
Therefrom; In pure qi (oxygen) body-thick gas heat exchanger 134, be heated to the thick gas of for example about 620 ℃ preheat temperature from its initial temperature; Reach in the burner 104 through thick gas access 154 in case of necessity with from the fuel mix of fuel conduit 106 ground, and reach therefrom in the combustion chamber 102.There; The oxidable component and the fuel of thick gas are oxidized in exothermic reaction; Produced thus and had the pure qi (oxygen) body that for example is about 750 ℃ of temperature; This pure qi (oxygen) body from combustion chamber 102 deviate from burner distolateral 178 through pure qi (oxygen) body passage 168 against flow direction 204 flow be back to pure qi (oxygen) body-thick gas heat exchanger 134 in the end of burner side, the pure qi (oxygen) body reach there pure qi (oxygen) body-thick gas heat exchanger 134 Tube Sheet of Heat Exchanger 138 in the end of burner side and the end that deviates from burner 104 that in interior heat exchanger space 140, flows to pure qi (oxygen) body-thick gas heat exchanger 134 that forms in inner space along flow direction 204 through Tube Sheet of Heat Exchanger 138.
Because in all adjusting positions of pure qi (oxygen) body-thick gas heat exchanger 134; All pure qi (oxygen) bodies are percolation pure qi (oxygen) body passage 168 all; So in all these adjusting positions; Waste gas keeps ground to obtain in the whole time of staying in the scope of combustion chamber 102 until getting into pure qi (oxygen) body-thick gas heat exchanger 134, and cooling exhaust in the case not.Realized the complete oxidation of the oxidable component of thick gas thus.
Pass through to the pure qi (oxygen) body of discharge temperature TA that heat transmission on the thick gas is cooled to depend on the adjusting position of pure qi (oxygen) body-thick gas heat exchanger 134; Reach the pure qi (oxygen) body accumulation chamber 228 from the heat exchanger space 140 interior of pure qi (oxygen) body-thick gas heat exchanger 134; And arrive rearmounted in case of necessity heat exchanger through pure qi (oxygen) body pipeline 164 therefrom, the pure qi (oxygen) body is further passing to one or more other fluid media (medium)s with heat under the cooling there.
And then the pure qi (oxygen) body is discharged to surrounding environment through waste stack.
The waste gas purification facility 100 of heating power structurally is designed with definite pure qi (oxygen) body discharge temperature T according to the operating point of confirming A
Because the waste gas purification facility 100 of heating power relates to the whole steel construction of rigidity basically, so this preset meter (under the situation by the given in advance entering temperature of thick gas source 114 of thick gas) has been confirmed the height of discharge temperature basically.
Because through can improving when needed through utilizing by-pass collar 126 with pure qi (oxygen) body-thick gas heat exchanger 134 that aforementioned manner is regulated; But can not reduce the discharge temperature of pure qi (oxygen) body; So meaningfully, the operating point of the waste gas purification facility 100 of heating power is not to design on the specified discharge temperature of pure qi (oxygen) body under the situation of using by-pass collar 126, but design is on lower slightly temperature; Decision design is on low at least 10 ℃ temperature, on especially low about 20 ℃ temperature.
At the run duration of the waste gas purification facility 100 of heating power, can adjust the pure qi (oxygen) body discharge temperature T of actual needs then through the adjusting by bypass flap 212 and heat exchanger valve 208 of pure qi (oxygen) body-thick gas heat exchanger 134 A
In the stage that the less heat through rearmounted heat exchanger descends, then for example in producing time-out, can be adjusted on the low pure qi (oxygen) body discharge temperature of trying one's best of operating point, so that save energy.
The waste gas purification facility 100 of heating power second kind of form of implementation shown in Fig. 3 to Figure 14 aspect the structure of its principle and its working method with consistent in first kind of form of implementation shown in Fig. 1 and Fig. 2.
Especially also be applicable to second kind of form of implementation of the waste gas purification facility 100 of heating power by the principle calcspar of Fig. 1.
The difference of second kind of relative first kind of form of implementation of form of implementation is; Under the situation of second kind of form of implementation; The section 150 that is in thick gas access 132 and sneaks between the equipment 148 in heat exchanger space 144 outside will be longer than the equipment of sneaking into 148 that is in heat exchanger space 144 outside and the end section 152 between the thick gas vent 146; Residual fluid flows in the heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134 on thick gas access, and total fluid stream of joining together once again of thick gas is discharged by heat exchanger space 144 outside on thick gas vent.
In second kind of form of implementation, bypass flow stream is just sneaked into when residual fluid stream has had than temperature higher in first kind of form of implementation then.
Under the situation of second kind of form of implementation, the possible reduction of the efficient of pure qi (oxygen) body-thick gas heat exchanger 134 is (and thus to pure qi (oxygen) body exhaust temperature T thus AThe control band that can get at) can be greater than under the situation of first kind of form of implementation.
In addition, sneak into equipment 148 sneak into position 220 under the situation that extends in second kind of form of implementation on the direction of longitudinal axis 174 also greater than under the situation of first kind of form of implementation.
Especially, form under the situation of second kind of form of implementation sneak into position 220 pass through gap 218 at the average headway two holding element 190 of the direction of longitudinal axis 174 on before and after in succession following between of the extension on the direction of longitudinal axis 174 greater than pure qi (oxygen) body-thick gas heat exchanger 134.
Bypass passageways end wall 216 be not as under the situation of first kind of form of implementation, to be circular cone hull shape ground structure basically under the situation of second kind of form of implementation, but is annular ground structure basically.
Stability mechanically for the adjacent boundary region of the stability mechanically that improves bypass passageways end wall 216 and bypass shell body 214; Situation second kind of form of implementation is arranged with reinforcing element 232; For example form is leg-of-mutton approximately gusset, and these gussets preferably equidistantly distribute and the sealed ground of material not only had been connected with bypass passageways end wall 216 but also with bypass shell body 214 along the periphery of bypass passageways end wall 216 basically.
In addition, under the situation of second kind of form of implementation, outer cover of heat exchanger body 182 face bypass passageways end wall 216, be provided with at the edge 234 that the upstream side boundary is sneaked into position 220 ringwise around crimp 236 so that strengthened edge 234.
Very big expansion through sneaking into heat exchanger space 144 through outside on thick gas flow direction, position 220 reaches as follows; That is, bypass flow stream and residual fluid flow mixes mainly in the blending space 238 outside being in heat exchanger tube 136 radially and carries out.
Avoided cold bypass flow stream directly to be carried in the Tube Sheet of Heat Exchanger 138 of sneaking in 220 zones, position thus; This can cause very high heating power stress, because the zone at the downstream that are in the zone of sneaking into position 220 of Tube Sheet of Heat Exchanger 138 and the upper reaches contacts with the thick gas of higher temperature.
But through the displacement of blending space 238 in the zone that is in outside the heat exchanger tube 136; At first arrive Tube Sheet of Heat Exchanger 138 through the mixture that is made up of bypass flow stream and residual fluid stream of sneaking into generation, this mixture has than the cold separately higher temperature of bypass flow stream.
Help in addition mixed process is displaced to and in the zone outside heat exchanger tube 136 be; In the zone of sneaking into position 220 of the equipment of sneaking into 148, be furnished with pure qi (oxygen) body-thick gas heat exchanger 134 at interior holding element 190a and the holding element 190b not being arranged in outside, thereby the pressure residual fluid flows through the side of the radial direction outer of holding element 190a.
Fig. 4 to Figure 14 shows the details of second kind of form of implementation of the waste gas purification facility 10 of heating power; These details are constructed under the situation of first kind of form of implementation identically or can be constructed identically, but can not discern so significantly in the only profile (Fig. 2) by first kind of form of implementation.
Therefore the holding element 190a in Fig. 4 shows and is passed in radially at the vertical section in interior zone; Should have the piston shoes 196 that adhere to above that at interior holding element, these piston shoes can slide on the direction of longitudinal axis 174 on the outside of heat exchanger inner housing 184.
Fig. 5 shows the vertical section in the end of burner side that passes two Tube Sheet of Heat Exchanger 138, and these two Tube Sheet of Heat Exchanger are connected with holding element 190 materials of pure qi (oxygen) body-thick gas heat exchanger 134 sealedly, especially welding.
Fig. 6 shows the vertical view on the end regions that deviates from burner 104 of the waste gas purification facility 100 from the top to heating power, especially can be known by this vertical view and see the separation equipment 124 that has bypass hoistway 210 and adjacent entering hoistway 206.
But but the cross section by thick gas percolation that gets into hoistway 206 is preferably greater than the cross section by thick gas percolation of bypass hoistway 210.
Fig. 7 shows the vertical cross-section of the waste gas purification facility 100 of the heating power in the zone of sneaking into position 220 that is passed in the equipment of sneaking into 148.
Can see by Fig. 7 and Fig. 8 that the cross section that only passes heat exchanger tube 136 is shown; Under the situation of second kind of form of implementation; Heat exchanger tube 136 comprises three Tube Sheet of Heat Exchanger layers 188; Wherein, the Tube Sheet of Heat Exchanger 138 of different heat exchange organ pipe layer 188 has apart from the different radial spacing of longitudinal axis 174.
Fig. 9 has illustrated the vertical cross-section of the waste gas purification facility 100 that passes heating power in like lower area, in this zone, the bypass passageways 130 of by-pass collar 126 is around the section 150 in the heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134.
By Fig. 9 with show the Figure 10 that is arranged in the restricting element ringwise 222 in the bypass passageways 130 separately and can see that restricting element 222 is provided with a large amount of ringwise through holes 224, these through holes are preferably followed before and after equidistantly along the periphery of restricting element 222 in succession.
But can be like the ratio of the entering cross-sectional area of the maximum percolation of the gross area that under the situation of first kind of form of implementation, is chosen in the through hole 224 in the restricting element 222 and by-pass collar 126.
Figure 11 to Figure 14 shows the details to the embodiment of the separation equipment 124 of by-pass collar 126 at last, has the driving arrangement 240 of the adjustment campaign that has connected that is used to drive bypass flap 212 and heat exchanger valve 208.
As preferably by Figure 11 and Figure 12 appreciable, bypass flap 212 and heat exchanger valve 208 can 244 being bearing on the bypass hoistway 210 in the mode that pivots between open position and the closed position and getting in other words on the hoistway 206 around each turning cylinder 242 in other words.
Preferably can see by Figure 12; Bypass flap 212 is in its open position just; In this open position, bypass flap has discharged the maximum that flows in the by-pass collar 126 to bypass flow stream and has got into cross section, and heat exchanger valve 208 is in its closed position simultaneously; In this closed position, heat exchanger valve 208 has stoped thick gas to get in the section 150 in heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134.
In this position of bypass flap 212 and heat exchanger valve 208, bypass flow stream therefore account for the total thick gas stream in the waste gas purification facility 100 that gets into heating power volume share 100%.
Turning cylinder 242 and 244 is via being coupled to each other in this wise at the parallelogram guide rod 246 shown in Figure 14; Thereby make that when the turning cylinder 242 of bypass flap was moved pivotally by driving, bypass flap 212 was reciprocally implemented same big pivoting action with heat exchanger valve 208.
This pivoting action triggers by electric drive motor 248; This electric drive motor has produced the moving of free end of the orthoscopic guiding of bar 249 through rotating spindle device 250; This bar is hinged on through hinge 251 on other the bar 252, and this other bar itself is anti-to be connected with turning cylinder 242 with relatively rotating.
If bypass flap 212 control signal based on the control appliance of the waste gas purification facility 100 of heating power in the open position shown in Figure 12 is pivoted in its closed position, side by side heat exchanger valve 208 is moved to the open position from its closed position through two valve 212 and 208 connections so via parallelogram guide rod 246.
Through open position and the adjustment in the centre position between the closed position separately that be in of valve 212 and 208, the thick gas stream that gets in the waste gas purification facility 100 of heating power can be to be divided into bypass flow stream and to flow with residual fluid in order to regulate each ratio that needs of pure qi (oxygen) body discharge temperature TA.
In Figure 15, be in the third form of implementation of the waste gas purification facility 100 of the heating power shown in the schematic block diagrams and the difference of first kind of form of implementation shown in Fig. 1 and Fig. 2; The pure qi (oxygen) body-slightly gas heat exchanger 134 is not by the pure qi (oxygen) body under the interior situation of heat exchanger space 140 in the third form of implementation; But coming percolation by thick gas, percolation is come by the pure qi (oxygen) body in that the situation of this form of implementation is next in the heat exchanger space 144 outside of and pure qi (oxygen) body-thick gas heat exchanger 134.
Under the situation of this form of implementation, fluid media (medium) and thick gas that the pure qi (oxygen) body and function is done outside are used as at interior fluid media (medium) thus.
Therefore under the situation of this form of implementation; By-pass collar 126 is not to be arranged in thick gas side; But be arranged in the pure qi (oxygen) side; By this by-pass collar, the part of fluid stream outside is guided the section 150 through the heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134, so that reduce the efficient of pure qi (oxygen) body-thick gas heat exchanger 134 when needed.
Thus; By-pass collar 126 comprises the separation equipment 124 on the pure qi (oxygen) body inlet that is arranged in pure qi (oxygen) body-thick gas heat exchanger 134 under the situation of this form of implementation; From the part of the pure qi (oxygen) body of combustion chamber 102 stream by this separation equipment as bypass flow stream can with the residual fluid flow point of pure qi (oxygen) body from and can flow to the equipment of sneaking into 148 through bypass passageways 130; Bypass flow stream can be sneaked into again in the residual fluid stream of pure qi (oxygen) body, after this residual fluid flows the section 150 in the heat exchanger space 144 outside of having passed through pure qi (oxygen) body-thick gas heat exchanger 134 by the equipment of sneaking into.
Because under the situation of this form of implementation; The efficient of pure qi (oxygen) body-thick gas heat exchanger 134 can be through the adjustable share guiding of whole pure qi (oxygen) body stream is lowered with affined mode through the section 150 in the heat exchanger space 144 outside of pure qi (oxygen) body-thick gas heat exchanger 134, so under the situation of this form of implementation, also can regulate pure qi (oxygen) body discharge temperature T through the adjusting of pure qi (oxygen) body-thick gas heat exchanger 134 A
In addition; The third form of implementation of the waste gas purification facility 100 of the heating power shown in Figure 15 make up with function aspects all with first kind of form of implementation and also consistent shown in Fig. 1 and Fig. 2 with second kind of form of implementation shown in Fig. 3 to Figure 14, thus can be with reference to their above stated specification.
