In one embodiment, referring to fig. 1 of the specification, the low-temperature gas-liquid mixing device provided by the invention is described, and the low-temperature gas-liquid mixing device provided by the invention can improve the mixing degree between high-temperature gas and low-temperature liquid, and realize the full mixing of the high-temperature gas and the low-temperature liquid, so that a large amount of gas medium meeting the requirements is output, and the improvement of the working efficiency is facilitated.
Referring to fig. 1 of the specification, the low-temperature gas-liquid mixing device provided by the invention comprises a pressure-bearing cylinder 2 with a hollow inside, wherein a gas inlet 1 and a gas outlet 9 are respectively arranged at two ends of the pressure-bearing cylinder 2, and the gas inlet 1 and the gas outlet 9 are suitable for inputting and outputting high-temperature gas media.
Further, the wall of the pressure-bearing cylinder 2 is provided with at least one through hole, and a liquid input component is inserted into the through hole and is used for inputting a low-temperature liquid medium into the pressure-bearing cylinder 2.
Specifically, the liquid input assembly is provided with a liquid nozzle 3, the liquid nozzle 3 is detachably connected with the pressure-bearing cylinder 2, the liquid nozzle 3 is located in the pressure-bearing cylinder 2 and is used for converting a low-temperature liquid medium into low-temperature liquid drops, and at least part of the low-temperature liquid drops are sprayed into the pressure-bearing cylinder 2.
When the high-temperature gas medium and the low-temperature liquid medium are input into the pressure-bearing cylinder 2, the high-temperature gas medium is mixed with the low-temperature liquid drops, so that the low-temperature gas medium is formed.
It is worth mentioning that the contact area of the low-temperature liquid medium and the high-temperature gas medium is increased by arranging the liquid nozzle 3, which is beneficial to the rapid cooling of the high-temperature gas medium and the improvement of the working efficiency; in addition, the liquid nozzle 3 and the pressure-bearing cylinder 2 are detachably connected, so that the flexibility of the device can be improved, and the device accords with different working condition environments.
In addition, the number of through holes formed in the wall of the pressure-bearing cylinder 2 is not excessively limited in this embodiment, only one through hole is required to be formed, and the through holes in this embodiment only have the effect of enabling the liquid nozzle 3 to extend into the pressure-bearing cylinder 2, so that the low-temperature liquid medium is sprayed into the pressure-bearing cylinder 2, and the more through holes are conceivable, the more liquid nozzles 3 can be connected, so that the larger liquid input amount is realized, and therefore, the technical staff can increase or decrease the number of the through holes according to the requirement, so as to ensure the effective output of the gas medium.
Further, the inner periphery of the pressure-bearing cylinder 2 near the side of the gas inlet 1 is also provided with a backflow prevention weir plate 6, and the backflow prevention weir plate 6 extends to the central position of the gas inlet 1 to form partial shielding relative to the gas inlet 1, so as to prevent part of the low-temperature liquid medium from flowing back to the upstream pipeline through the gas inlet 1.
In one embodiment, the number of through holes is greater than or equal to two, each through hole is connected with a liquid input assembly, and the liquid nozzle 3 comprises a large-flow nozzle and a small-flow nozzle, wherein the large-flow nozzle is used for providing high spraying flow, and the small-flow nozzle is used for providing low spraying flow.
The high-flow nozzle and the low-flow nozzle can be independently used or combined, so that the low-temperature gas-liquid mixing device can be used for a low-flow working condition or a high-flow working condition.
It can be understood that by arranging the large-flow nozzle and the small-flow nozzle to cope with different flow working conditions, the high-temperature gas medium and the low-temperature liquid medium can be more fully mixed, and the whole medium cooling process can be more controllable by independently or jointly using the large-flow nozzle and the small-flow nozzle to adjust the spraying quantity or the spraying angle; the combination mode can be that a large-flow nozzle and a small-flow nozzle are arranged, or a large-flow nozzle and two small-flow nozzles are arranged and combined, so long as the output quantity of the medium can be ensured, the combination mode can be used.
On the basis of the above embodiment, each liquid nozzle 3 is provided with a plurality of spray holes, and the plurality of spray holes are distributed in the liquid nozzle 3 in a preset array.
The spray holes can be positioned on one side of the liquid nozzle 3 facing the gas inlet 1 or on one side of the liquid nozzle 3 facing the gas outlet 99, and in both cases, the liquid nozzle 3 forms a single-side spray; of course, the spray holes may be disposed at two opposite sides of the liquid nozzle 3, so that the liquid nozzle 3 forms a double-sided spray.
The form, number and arrangement of the spray holes can also have a certain influence on the spray quantity, the spray area and the like, and the specific form is not limited in the embodiment, and is described in detail later.
In another embodiment, at least some of the orifices in the low-flow nozzle are tapered orifices, the longitudinal cross-sectional area of the tapered orifices monotonically decreasing with spray direction to form a tapered spray shape.
When the spray hole of the small-flow nozzle is arranged to be a conical hole, a stable spray shape can be provided, and the diameter of liquid drops formed during spraying is smaller, so that the liquid drops can be fully mixed with a high-temperature gas medium, and the low-temperature liquid medium is saved to a certain extent, thereby being beneficial to the reduction of cost.
It can be understood that in this embodiment, the diameter of the side close to the interior of the receiving cylinder is small, and the diameter of the side far from the interior of the receiving cylinder is large, so that when the cryogenic liquid medium is fed into the pressure-bearing cylinder 2, a certain amount of the cryogenic liquid medium can be collected on the large-diameter side and then conveyed to the pressure-bearing cylinder 2 on the small-diameter side, so that the cross-sectional area of the flow passage provided for the cryogenic liquid medium is gradually reduced, and a certain flow velocity of the medium can be maintained when the cryogenic liquid medium is conveyed. Meanwhile, due to the arrangement of small diameter, the low-temperature liquid medium can form a plurality of liquid drops with smaller diameter through the conical holes when being sprayed, so that the spraying flow is finer, and the high-temperature liquid medium can be fully mixed with the high-temperature gas medium.
In other embodiments, the shape of the orifice of the low-flow nozzle may be adjusted or modified, and the orifice form of the low-flow nozzle may be combined, for example, the above-mentioned tapered hole may be combined with another type of B hole, and the diameter of the B hole may be slightly smaller than that of the tapered hole. The conical hole is arranged on the side of the liquid nozzle 3 facing the gas inlet 1, the B hole is arranged on the side of the liquid nozzle 3 facing away from the gas inlet 1, or one or more circles of B holes are arranged on the outermost side of the conical hole, so that a mixed spray flow is formed, and similar many modifications are included in the protection scope of the invention.
In one embodiment, at least some of the orifices in the high-flow nozzle are circular orifices 31, and the cross-section of the circular orifices 31 is a plurality of concentric circles of equal diameter.
In other embodiments, at least some of the spray holes in the high-flow nozzle are grid-shaped holes 32, the cross sections of the grid-shaped holes 32 are all in a strip-shaped profile, and the grid-shaped holes 32 are uniformly distributed along the length direction of the liquid nozzle 3.
As is readily understood from the foregoing, two types of spray hole forms of the large-flow nozzle, that is, the circular hole 31 or the grid-shaped hole 32, and the spraying amount of the grid-shaped hole 32 is larger than that of the circular hole 31, so that the device is suitable for a large-flow working condition, the spraying angle and the spraying area of the circular hole 31 are more controllable relative to those of the grid-shaped hole 32, the operability is improved, the number of the circular hole 31 or the grid-shaped hole 32 is also related to the spraying amount, and a technician can increase or decrease the number according to the overall size of the device, which is not particularly limited in the embodiment.
In particular, the circular holes 31 are provided in a form that can be seen with reference to fig. 3 and 4, in which the cross-section of the circular holes 31 is not shown, but it is easily understood that the circular holes 31 are also similar to conventional through holes.
In the figure, "d" is the distance between the centers of the adjacent circular holes 31, the distance d is equal in length, and the included angles formed by the connecting lines of the centers of the three circular holes 31 in the figure are 60 degrees, so that a plurality of equilateral triangles can be formed by the arrangement.
The circular holes 31 form the whole spraying surface in the drawing, and can be regarded as uniformly diverging along the transverse direction and the longitudinal direction by an equilateral triangle, so that a plurality of rows and columns of spray holes are formed, and certain dislocation exists between the spray holes in each row and each column.
Referring to fig. 5 to 7, the grid-shaped holes 32 can be used in the form of the spray holes of the large-flow nozzle, and the spraying amount can be significantly improved due to the strip-shaped profile of the grid-shaped holes 32, so that when a large amount of high-temperature gas medium is input into the pressure-bearing cylinder 2, the low-temperature liquid medium can be sprayed timely and efficiently through the grid-shaped holes 32.
The gaps between the grid-shaped holes 32 can be adjusted, when the grid-shaped holes 32 are distributed on the liquid nozzle 3, the gaps between the grid-shaped holes 32 determine the density degree of sprayed low-temperature liquid drops to a great extent, so that when the working condition of large flow is processed, the gaps are generally in the range of 0.2-2mm, the production difficulty of the grid-shaped holes 32 can be brought if the gaps are too small, the normal spraying range can be influenced if the gaps are too large, and the cold and hot media can not be fully mixed.
Of course, the size of the above-described grating-shaped holes 32 and the manner of disposing on the liquid nozzle 3 may be modified in other embodiments, and if the grating-shaped holes 32 are small in size, a plurality of rows and columns may be disposed similarly to the above-described manner of disposing the circular holes 31; if the size of the grid-shaped holes 32 is large, it is sufficient to directly arrange a row by row, thereby forming a multi-layered output.
In one embodiment, as shown in fig. 1, a gas-liquid mixed filler 4 is fixedly arranged at a position adjacent to the liquid input assembly, and the gas-liquid mixed filler 4 is arranged on the inner wall of the pressure-bearing cylinder 2 and is suitable for receiving low-temperature liquid drops formed by spraying of the liquid nozzle 3, so that the low-temperature liquid drops sprayed in the gas-liquid mixed filler 4 are mixed with a high-temperature gas medium, and the temperature of the high-temperature gas medium is reduced.
It can be understood that the contact area of the low-temperature liquid medium and the high-temperature gas medium can be enlarged by the gas-liquid mixed filler 4, so that the low-temperature liquid medium and the high-temperature gas medium can be fully mixed, the gas medium can be rapidly cooled, the types of the gas-liquid mixed filler 4 are not limited in the embodiment, and metal filler, ceramic filler or plastic filler can be selected according to the actual conditions of manufacturers.
In addition, as can be understood from the drawings, the number of the gas-liquid mixing packing 4 may be increased according to the number of the liquid nozzles 3 or the length of the flow passage as a whole, so that the sufficient mixing of the gas and the liquid is achieved by the plurality of packing.
Further, the gas-liquid mixed packing 4 is fixed to the inner wall of the pressure-bearing cylinder 2 through a support plate.
In one embodiment, the support plate has a corrugated structure and is provided with through holes, so that the gas medium or the liquid medium can smoothly flow, and the thorough mixing is facilitated. Of course, in other embodiments, the corrugated structure of the support plate may be modified, for example, to a grid support plate or the like.
In another embodiment, a deflector 5 is further disposed in the pressure-bearing cylinder 2, the deflector 5 is disposed corresponding to the gas-liquid mixed filler 4, and a flow guiding surface of the deflector 5 faces the gas inlet 1, so as to rectify a low-temperature gas medium formed by a high-temperature gas medium and a low-temperature liquid medium.
