Description

Control fluid unit and flow guide device

Technical Field

The present invention relates to the field of gas transmission technologies, and in particular, to a fluid control unit and a flow guide device.

Background

Many industrial processes produce large quantities of industrial gases, some of which are directly discharged to meet environmental requirements, some of which require waste heat recovery, some of which require dust removal, and some of which require physical or chemical reactions to remove harmful components, etc. These large quantities of industrial gases require pipelines with large cross-sectional dimensions during transportation, and at the same time, the gas transportation may be subjected to multiple changes of direction, which may cause uneven airflow, delamination, turbulence and even eddy in the pipelines. These industrial gases are used in different applications, and the requirements for use of the subsequent equipment are different, and generally, it is desirable that the industrial gases uniformly enter the subsequent equipment in the flow passage section.

In industrial production, various industrial gas conveying modes are provided, and rectangular pipelines are used in many cases for large-flow gas conveying, and have the characteristics of easiness in manufacturing and uniform gas flow distribution and are widely used; however, when the rectangular pipeline turns, the uniform flow field of the airflow is broken, which can cause local scouring of equipment and turbulence of the airflow, and influence the use and treatment of the gas. In order to prevent turbulence and even vortex when the airflow changes direction, a guide plate or a baffle plate is arranged in the pipeline to limit the flow direction of the airflow, so that the airflow passes through the bend in a plug flow manner, and the guide function is achieved, but the uniform distribution of the flow in the section of the pipeline cannot be guaranteed.

For example, the current practice of a device manufacturer is shown in FIG. 1: when the air flow passes through the pipeline elbow, the air flow can basically keep the original flow field state under the limitation of the guide plate 01.

By adopting the method for arranging the guide plate 01 on the elbow of the pipeline, the airflow can basically keep the original flow field state, but the phenomenon of uneven flow field in the section of the pipeline cannot be improved; after the guide plate 01 is additionally arranged, airflow is layered, and new small-amplitude disorder can be generated in the layer after passing through the elbow. This technique does not distribute the flow of air evenly within the cross-section of the duct.

There is also a flue gas particle separating device in the prior art, and as shown in fig. 2 and 3, a dry type separating device for converter flue gas particles is proposed. The technique is that a shell is arranged at the tail end of a vaporization cooling flue, and a flue gas particle separation device is arranged in the shell and consists of a plurality of layers of parallel inclined plates 02 which are arranged at certain intervals; the flue gas is cut apart into a plurality of flat plunger flows when flowing through the device, can subside the flue gas granule fast and can be to the flue gas flame proof. Through setting up suitable swash plate interval and inclination can spread the flue gas granule of the meter level fast.

However, the above flue gas particle separating device has the disadvantage that when the flue gas containing dust flows through the multilayer inclined sedimentation plates, the flow velocity at each position in the whole cross section may be uneven, and the phenomenon of local too fast flow velocity occurs, so that the dust in the flue gas is difficult to settle and the satisfactory flue gas particle separating effect cannot be achieved.

In the prior art, there is also a flue gas diversion system and a waste heat boiler (the publication number is CN210141578U, the publication date is 3/13/2020), and as shown in fig. 4, a diversion device for an air inlet of the waste heat boiler is provided. The technology is characterized in that a flow guide mechanism 04 (comprising a flow guide plate and a rotating mechanism) is arranged in an air inlet flue 03 of the waste heat boiler, a plurality of flow velocity measuring points are arranged in an inlet cross section of the waste heat boiler 05, and the corresponding angle of the flow guide plate is adjusted through the rotating mechanism arranged on the outer side of the flue according to the numerical value of each flow velocity measuring point, so that the effect of approximately uniform flow velocity in the cross section of an air inlet is finally achieved.

However, the above flue gas diversion system has the following disadvantages: (1) due to the limitation of the temperature resistant range of the flow sensor, the application range of the diversion adjusting system has certain limitation. (2) The guide plate is transversely arranged in the cross section of the flue, the flow velocity of the incoming flue gas can be adjusted in the longitudinal direction, and the adjusting effect in the horizontal direction is very limited. (3) The flow guide device needs to be matched with control systems such as data acquisition, data analysis and automatic adjustment, and the investment and the operating cost are increased.

Therefore, the inventor provides a control fluid unit and a flow guide device by experience and practice of related industries for many years, so as to overcome the defects of the prior art.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.

As shown in fig. 5, the present embodiment provides a control fluid unit 1, which includes a box 11, the box 11 has an air inlet panel 12 and an air outlet panel 13 that are oppositely disposed, at least one air inlet hole 121 is disposed on the air inlet panel 12, a plurality of air outlet holes 131 are disposed on the air outlet panel 13, and the total area of the air outlet holes 131 is greater than the total area of the air inlet holes 121.

The number of the air inlet holes 121 and the air outlet holes 131 can be determined according to actual needs, and the shapes of the air inlet holes 121 and the air outlet holes 131 can be circular, square, long circular or rectangular, and the like, and specifically, the total area of the air outlet holes 131 is ensured to be larger than the total area of the air inlet holes 121 as long as the total area of the air outlet holes 131 is ensured to ensure that the air flow can be depressurized twice when passing through the air inlet panel 12 and the air outlet panel 13 successively. For example, as shown in fig. 5, the air inlet panel 12 is provided with 1 air inlet hole 121, the shape of the air inlet hole 121 is oblong, the air outlet panel 13 is provided with 18 air outlet holes 131, and the shape of the air outlet holes 131 is circular. The air outlets 131 on the air outlet panel 13 should be uniformly arranged to ensure that the flow rates of the air outlets 131 are approximately equal.

Therefore, in the control fluid unit 1 of the embodiment, the air inlet panel 12 and the air outlet panel 13 are respectively provided with the air inlet holes 121 and the air outlet holes 131, and the total area of the air outlet holes 131 is ensured to be larger than the total area of the air inlet holes 121, so that the whole control fluid unit 1 forms a double-layer flow guide structure; when industrial gas passes through the fluid control unit 1, the industrial gas sequentially passes through the air inlet hole 121 and the air outlet hole 131, the air flow is decompressed twice, the flow velocity in the cross section of the pipeline can be uniformly distributed, local too fast scouring of follow-up equipment caused by uneven flow field is avoided, the phenomenon of turbulence and vortex of the air flow is prevented, the problems of uneven flow velocity, airflow layering, turbulence and even vortex of the industrial gas in the transmission process are effectively solved, and the gas use and treatment of the follow-up equipment are met.

Preferably, the number of the air outlet holes 131 is greater than that of the air inlet holes 121, so that the whole flow field is more uniform after the air flows out of the air outlet holes 131 and is diffused. The shape and size of each air outlet 131 on the air outlet panel 13 are the same, which is not only convenient for processing and manufacturing, but also can ensure that the flow velocity of each air outlet 131 is more uniform. In addition, because the air velocity at the air inlet hole 121 is high, the scouring is serious, and the air inlet panel 12 needs to be made of special high-strength materials, such as heat-resistant steel, stainless steel or wear-resistant steel.

Further, as shown in fig. 5 to 12, the present embodiment further provides a flow guiding device 2, which includes a plurality of the above-mentioned control fluid units 1 that are spliced with each other, the air inlet panels 12 of the control fluid units 1 are all located on the same side of the flow guiding device 2 and are spliced to form an air inlet wall 21, and the air outlet panels 13 of the control fluid units 1 are all located on the same side of the flow guiding device 2 and are spliced to form an air outlet wall 22.

The whole diversion device 2 can form the diversion wall with various structural forms after splicing and combining the plurality of control fluid units 1 and can be arranged in the industrial gas conveying pipeline, the tail end of the pipeline or the inlet end of subsequent equipment and the like; when the gas flows through the flow dividing wall, the gas passes through double-layer wall holes formed by the air inlet wall 21 and the air outlet wall 22, the pressure is reduced for two times, the effect of uniform flow velocity of the air outlet holes 131 is achieved, and flow fields in the cross section of the pipeline are uniformly distributed; the phenomena of serious local scouring, layered and disordered airflow and even vortex caused by the turning of the gas conveying pipeline are avoided, and the potential danger of blasting exists when the conveying medium is high-temperature flue gas. The technology can provide a better flow field state for subsequent gas use or treatment, and the whole flow guide device 2 does not need to provide additional power energy, has a simple structure and low cost, and is an environment-friendly structure.

More specifically, the shape of the box 11 in the control fluid unit 1 and the shape of the whole flow guide device 2 formed by assembly can be determined according to the cross-sectional shape of a conveying pipeline, the cross-sectional shape of a pipeline tail end or a subsequent equipment inlet end and the like, and the flexibility is strong. To facilitate the splicing assembly, the housing 11 in the control fluid unit 1 is preferably of a hexahedral structure.

For example, the flow guiding device 2 may adopt the following structural forms:

the first method comprises the following steps: as shown in fig. 6 and 7, the box 11 has a rectangular structure, and the plurality of control fluid units 1 are arranged in a single row in the transverse direction as shown in fig. 6 or in a single column in the longitudinal direction as shown in fig. 7, so that the air flow can be uniformly distributed in the linear direction.

And the second method comprises the following steps: as shown in fig. 8, the box 11 is a rectangular structure, and a plurality of control fluid units 1 are arranged in a plurality of layers and columns of rectangular arrays to form a flow dividing wall with a rectangular cross section, so that air flow can be uniformly distributed in a rectangular pipeline.

And the third is that: a plurality of control fluid unit 1 are arranged according to the single row circular arc, constitute curved reposition of redundant personnel wall, can be in the circular arc direction with the air current equipartition.

In this case, as shown in fig. 9, the box body 11 has a straight quadrangular prism structure, the bottom surface of the straight quadrangular prism is an isosceles trapezoid, and the air inlet panel 12 and the air outlet panel 13 are formed on two opposite side surfaces (i.e., two side surfaces adjacent to the upper bottom and the lower bottom of the isosceles trapezoid) of the straight quadrangular prism structure; the other two opposite side surfaces (i.e. two side surfaces adjacent to two waists of the isosceles trapezoid) in the straight quadrangular prism structure are used for splicing with the corresponding side surfaces in the adjacent straight quadrangular prism structure. The division wall assembled by the plurality of control fluid units 1 is approximately arc-shaped. Of course, in this case, the air inlet panel 12 and the air outlet panel 13 may be designed as arc-shaped panels and then sequentially spliced to form an arc-shaped splitter wall.

And fourthly: as shown in fig. 10 to 12, the plurality of control fluid units 1 are arranged in multiple layers along the circumferential direction to form a cylindrical flow dividing wall, at this time, the air inlet panel 12 of each control fluid unit 1 is located inside the flow guiding device 2, the air outlet panel 13 of each control fluid unit 1 is located outside the flow guiding device 2, and the airflow is uniformly discharged from the cylinder after being depressurized twice in the cylinder, so that the function of uniformly distributing the airflow can be realized.

In this case, in order to facilitate installation and maintenance and to improve the service life of the control fluid unit 1, the flow guiding device 2 further includes an upper water-cooling loop 23 and a lower water-cooling loop 24 which are arranged at intervals up and down, and a plurality of water-cooling tubes 25 which are connected between the upper water-cooling loop 23 and the lower water-cooling loop 24 and are arranged at intervals in the circumferential direction. A plurality of limiting blocks 26 are fixedly arranged on each water-cooling tube 25 from top to bottom at intervals, and the box body 11 of the control fluid unit 1 is clamped between two adjacent water-cooling tubes 25 and connected with the limiting blocks 26.

Specifically, each water-cooled tube 25 is evenly arranged along the circumference, the water-cooled tube 25 is mutually communicated with the upper water-cooled ring pipe 23 and the lower water-cooled ring pipe 24, circulating cooling water is introduced into the water-cooled tube 25, each control fluid unit 1 in the flow guide device 2 can be cooled, and the water-cooled tube can be applied to the control fluid units 1 when a conveying medium is high-temperature flue gas, so that the water-cooled tube has a better protection effect and the service life of the control fluid units 1 is prolonged. It can be understood that the water cooling pipes 25 are generally circular pipes, and the side surface of the box 11 of the control fluid unit 1 close to the water cooling pipes 25 has a partial arc surface, which can be tightly attached to the water cooling pipes 25 to ensure that no gap exists between the control fluid unit 1 and the water cooling pipes 25 after the control fluid unit and the water cooling pipes 25 are fixed, and the air flow only enters from the air inlet holes 121. The general stopper 26 welds on water-cooling pipe 25, adopts welded mode fixed between box 11 of control fluid unit 1 and the stopper 26, compares in directly with each control fluid unit 1 welding together, and this mode both is convenient for assemble the concatenation, is convenient for later maintenance again.

Preferably, the bottom surface of the box body 11 of each control fluid unit 1 is obliquely and downwards arranged from the air outlet panel 13 to the air inlet panel 12, so that smoke particles can automatically slide downwards conveniently, and the separation effect of the smoke particles is improved; the specific inclination angle can be determined according to actual needs, and the angle between the bottom plate of the box body 11 and the horizontal plane is 5-70 degrees. A common limiting block 26 is a rectangular plate, one end of the limiting block 26 is welded with the water-cooling pipe 25, and the direction of the plate surface of the limiting block 26 is preferably arranged at the same inclination angle with the bottom surface of the box body 11; therefore, when each control fluid unit 1 is installed, only the box bodies 11 are needed to be placed between the adjacent water-cooling pipes 25 and the bottom surfaces of the box bodies 11 are enabled to be flush with the plate surfaces of the limiting blocks 26, and then the box bodies 11 and the limiting blocks 26 are welded, so that the operation is simple and convenient; and the bottom surface of box 11 is the same with stopper 26's face inclination, and the welding seam is the longest when both weld, and the welding of being more convenient for is just more firm.

Further, before the gas passes through the guide wall composed of multiple layers and multiple columns of control fluid units 1, the flow field is uneven, in order to ensure that the flow rates of the air outlet holes 131 are consistent, the sizes of the air inlet holes 121 of the control fluid units 1 in the areas with high flow rates are designed to be smaller, and the sizes of the air inlet holes 121 of the control fluid units 1 in the areas with low flow rates are designed to be larger. And the sizes and the arrangement of the air outlet holes 131 of the control fluid units 1 of the same guide wall are preferably the same, so that the flow field is more uniform after the flue gas is discharged and diffused through the air outlet holes 131. Therefore, it is preferable that the shape and size of the tank 11 of each control fluid unit 1 are the same; the number of the air inlet holes 121 of each control fluid unit 1 is the same, the size of the air inlet holes 121 of each control fluid unit 1 on the same layer is the same, and the size of the air inlet holes 121 of each control fluid unit 1 is gradually reduced from top to bottom; the number and size of the air outlet holes 131 of each control fluid unit 1 are the same, so that the flue gas flow rate of each air outlet hole 131 is approximately equal.

In a specific example, as shown in fig. 10 and 12, a closed space structure is provided at the end of the evaporative cooling flue 3 of the steel converter, and the closed space is constituted by the internal space of the housing 4 of the settling device. An upper water-cooling ring pipe 23 is arranged at the upper part of the airtight space, the upper water-cooling ring pipe 23 is fixedly welded with a flange and is connected with the upper part of the shell 4, a plurality of water-cooling pipes 25 are uniformly welded on the upper water-cooling ring pipe 23 in the circumferential direction, a limiting block 26 is welded on each water-cooling pipe 25 according to a certain interval, and a plurality of layers of control fluid units 1 are welded among the water-cooling pipes 25 through the limiting blocks 26 to form a cylindrical shunting wall; the lower end of the water-cooled tube 25 is welded to the lower water-cooled collar 24. In practical applications, two rings of hanging pipes 41 for water cooling are further connected to the outer side of the water-cooling pipe 25 on the upper water-cooling ring pipe 23, and two annular header pipes 42 are further provided at the lower portion of the housing 4, and these two header pipes 42 are respectively connected to the two rings of hanging pipes 41 for water cooling of the corresponding portion inside the housing 4. When the sizes of the control fluid unit 1 are designed, the speed reduction process should be ensured when the flue gas enters the air inlet hole 121, so as to ensure the pressure reduction effect.

In this example, the upper end of the housing 4 is connected to the end of the evaporative cooling flue 3 of the steelmaking converter, the high-temperature flue gas of the converter is discharged from the end of the flue and enters the sealed space structure, the high-temperature flue gas flows in from the air inlet holes 121 of the control fluid unit 1, the air outlet holes 131 flow out, and the air pressure is reduced twice to realize uniform-speed discharge, so as to meet the requirement of subsequent flue gas treatment.

Of course, the shapes of the plurality of control fluid units 1 in the flow guide device 2 and the shape of the flow guide wall assembled by splicing may be determined according to needs, and the shapes and the sizes of the control fluid units 1 in the same flow guide device 2 may be the same or different, and are determined according to the distribution situation of the actual flow field of the industrial gas, which is only exemplified in this embodiment.
