The content of the invention

Idea of the invention is that providing a kind of shape according to blast pipe makes the increased side of the mixability of exhaust and fluid Method.

Solution is the method for mixing exhaust stream with the fluid in the blast pipe of gas extraction system, and wherein fluid passes through note Enter device and be injected into blast pipe, it is characterised in that following methods step：

A) quilt of the exhaust stream in the region of injection device on the direction of the flowing of the blast pipe in parallel to blast pipe Guiding,

B) fluid is injected into along the center position with the injection of se angle deviatings flow direction, and it is directly injected into cloth Put on the deflecting element in blast pipe,

C) at least one gold by being arranged on deflecting element and being risen at least in part with sv angles with reference to flow direction Belong to board member, exhaust stream is partly diverted to the center position of shunting with reference to flow direction from flow direction.

D) before and after deflecting element is hit, fluid is at least in part by the diversion component edge shunting direction of exhaust stream Conveying, and metal plate component water conservancy diversion is raised to shunting direction.Here, it is essential that, exhaust stream quilt before blender Metal plate component water conservancy diversion enters shunting direction, and the exhaust stream is significantly deviating from flow direction.The deflection se that fluid is injected into is at this In can change between 270 ° and 360 °.

Therefore, the fluid being injected into from side is transported and the whole profile full of blast pipe, Zhi Houxiang along center position Answer ground in the whole profile impingement mix device of blender, then mixed with exhaust stream.Even in because installing space, blast pipe is not Be it is straight but bending when, it is also to have that fluid direction of motion is influenceed by the deflecting element related to the series of blast pipe Profit.

One further idea is that fluid hits correcting plate at least in part before metal plate component, this correcting plate With reference to injection direction arrangement, and undergo water conservancy diversion at least in part and enter flow direction, then by with least one mixing member The static mixer water conservancy diversion of part is to several hybrid directionals, so as to be further mixed.Correcting plate is substantially arranged in metallic plate Parallel to metal plate component above part, the side of the metal plate component of fluid injection is distributed in.When the other parts of fluid stream When before reaching metal plate component via correcting plate from injection direction water conservancy diversion to flow direction, the fluid distrbution before blender Increase.

Advantageously, realized by multiple fins being arranged on metal plate component metal plate component with identical or not The angle for being same as sv rises, and wherein angle sv is between 0 ° and 85 °.Because fin rises, metal plate component may be disposed so that this Body is parallel to flow direction, so that only fin ensures the generation of the necessary water conservancy diversion of exhaust stream, so as to ensure the necessary water conservancy diversion of fluid Generation.

Another advantageously, correcting plate be included in boring direction extension multiple drillings, wherein boring direction with reference to stream Dynamic direction is extended with the angle bs between 45 ° and 135 °.Thus, a part for fluid can further pass through one or more correcting plates It is distributed in the profile of blender.So as to which fluid further can partly flow into injection device and partly by correcting plate water conservancy diversion. The accumulation part of fluid is transported by further water conservancy diversion and along the direction of flowing, and the non-accumulated part of the fluid through drilling Next correcting plate is reached along the direction of injection or the direction of metal plate component.

Correcting plate is arranged to parallel to flow direction and including multiple correction wings risen with reference to flow direction with angle sk Piece, wherein angle sk is between 95 ° and 265 °.Correction fin is stamped out on correcting plate, so that the fluid do not accumulated can pass through punching Swaging into opening flow through correcting plate.Meanwhile, fluid is by correction fin stabilization, so that compared to above-mentioned flow regime, fluid exists More slowly by exhaust stream water conservancy diversion on flow direction.

Set what multiple reference flow directions were risen with angle ms risings and with reference to shunting direction with angle mv on hybrid element Fin, wherein angle ms are 70 ° to the maximum, and angle mv is more than 1 °.For mixed process, it is advantageous that fluid is further mixed fin Water conservancy diversion, and will not be led further in the equidirectional of fin or correction fin decision.

For this method, the deflecting element for guiding exhaust stream and being used to be arranged in the blast pipe of gas extraction system is favourable , and the deflecting element is used for the liquid that gas extraction system is injected in holding by injection device, wherein deflecting element can be in tool Have at least one hybrid element metal plate component static mixer before positioned along flow direction, and including at least one The individual metal plate component that can be located in exhaust stream, wherein the metal plate component is joined at least in part on shunting direction Risen according to flow direction with angle sv, thus exhaust stream is entered shunting side from flow direction water conservancy diversion at least in part together with fluid To.It is formed at the angle sv fins risen on metal plate component.In order to realize in blast pipe profile and thus turn in part It is melted into the whole blender profile of gaseous fluid and realizes symmetrical shunting, metal plate component is directly arranged in flow direction Before blender.Gaseous parts are smaller, and influence of the deflecting element to the mixed process of blender is bigger.On shunting direction, gold Belong to board member relative to flow direction with angle sv by fin lifting at least in part, thus exhaust stream together with fluid by least portion Ground is divided to be guided to shunting direction from flow direction.The metal plate component parallel to flow direction is arranged in itself for water conservancy diversion Influence can be ignored.

The multiple fins risen with angle sv are formed on metal plate component.Using multiple fins, realization is distributed in blast pipe Profile fluid water conservancy diversion.Using multiple fins in flow direction arranged in succession, because fin realization is in flow direction Water conservancy diversion partly accumulated, the increase of the water conservancy diversion of flow element.

Deflecting element can be placed in blast pipe in one way so that fluid largely influences deflection member The direction of part.Thus, the speed of fluid is deflected element and reduced first, and then therefore flow direction can more easily be changed Become.

According to exhaust quality stream and delivery temperature, penetration depth and fluid rushing on deflecting element of the fluid in blast pipe Hit area change.

Deflecting element includes one or more be arranged to parallel to flow direction or parallel to the correction of metal plate component Plate.Correcting plate makes fluid down and allows fluid to relatively early low water conservancy diversion by exhaust stream.Correcting plate can include different length Spend or be designed to identical length.

Correcting plate includes the correction fin that one or more angle sk between 95 ° and 265 ° rise and multiple by school The opening transverse to flow direction of positive fin formation, and/or it is multiple boring the drilling of dynamic direction extension, wherein boring direction with Extended with reference to flow direction with the angle bs between 40 ° and 135 °.Alternately there is provided it is multiple boring direction extend Drilling, wherein boring direction with relative to flow direction between 45 ° and 135 ° angle bs extend.Thus, one of fluid Opening can be directly flowed through along its injection direction or drill without being decelerated by dividing.The correction and stably of flowing is realized by correcting plate.

Metal plate component protrudes past all correcting plates with reference to the opposite direction of flowing and metal plate component is with reference in injection Heart direction is disposed in after last correcting plate.Because therefore metal plate component is arranged to the blast pipe relative with decanting point Wall direct neighbor, sheet metal elements can influence injection fluid whole amount.

Deflecting element is designed on a central plane specular that right angle is formed with flow direction, or fin And/or correction fin is arranged on central plane specular.Because this is symmetrical, the center stream of the blast pipe of fluid injection Dynamic region can be influenceed to a greater extent, because center hybrid element or flow element have identical alignment thereof.

Advantageously, as described above multi-stage diffluence device including deflecting element and it is fixed on deflecting element or passes through At least one hybrid element is arranged in the static mixer after deflecting element indirectly, and wherein hybrid element is mixed including at least one Fin support or a flow element.Due to the combination of deflecting element and blender, efficient mixed method is possible.

Metal plate component or correcting plate are disposed on support or are disposed in parallel to flow direction or and flow direction In flow element diagonally.Thus, blender and deflecting element are designed at least part of or can also complete shape Integral and use identical material.

Fin or flow element are mixed with reference to flow direction to be up to 70 ° of angle ms and with reference shunting direction with super The angle mv for crossing 1 ° rises.
