Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, specifically to a continuous heat exchange device for reactive dye processing. Background Technology

[0002] As a core raw material in the textile printing and dyeing industry, reactive dyes involve multiple precise chemical reactions such as diazotization, coupling, and condensation in their processing. Each reaction stage has extremely stringent temperature control requirements. At the same time, reactive dye processing exhibits significant differences in thermal characteristics. Coupling and other reactions are exothermic, releasing a large amount of heat, while condensation and other reactions are endothermic, requiring continuous heat replenishment. Therefore, efficient heat exchange and heat recovery are crucial to ensuring the yield, quality, and economic efficiency of reactive dye production. However, existing heat exchange devices have a single heat exchange function, mostly plate heat exchangers or steam heat exchangers. For coupling reactions and condensation reactions, separate heat exchange devices need to be purchased, which increases costs and energy consumption. Existing heat exchange devices also have shortcomings in terms of continuous adaptation, heat exchange efficiency, structural flexibility, temperature accuracy and energy utilization.

The two ends of the several conduits are respectively fixedly connected to the first adapter ports between the outer guide rings. The several mother rings are all circular ring structures with the same diameter as the outer guide rings. The several mother rings are respectively fixedly fitted onto the several conduits and arranged between the outer guide rings. The left and right sidewalls of the several mother rings near the front end are respectively provided with second delivery ports arranged alternately. The second delivery ports of the several mother rings are connected in series through adapter pipes. The several first isolation plates are respectively fixedly arranged inside the front end of the mother rings, and the first isolation plates first isolate the inner cavity of the mother rings. The first isolation plates are located between the second delivery ports. The several adapter seats are respectively symmetrically arranged on the left sidewall of the mother rings, and the adapter seats are respectively located between a pair of conduits. The conduits can penetrate the support.

[0006] Preferably, the sub-heat exchange structure includes a plurality of sub-heat exchange components, each of which is detachably embedded in the mother ring, and the plurality of sub-heat exchange components are connected in series relative to each other through pipes.

[0007] Preferably, the sub-heat exchange assembly includes a sub-ring, a second baffle, a few turbulence plates, a pair of adapter plates, and bolts; the sub-ring is a hollow circular ring structure, and the outer diameter of the sub-ring is the same as the inner diameter of the mother ring.

[0012] Preferably, the second outlet is connected to the mother ring and the daughter ring connected in series.

[0013] The continuous heat exchange device for reactive dye processing proposed in this invention has the following advantages: 1. Heat utilization and energy saving: This solution directly addresses the typical industrial scenario of "heat transfer required for exothermic reactions and heat replenishment required for endothermic reactions" through a mother-daughter type annular heat exchanger, solving the pain points of "heat waste + high external energy consumption" of traditional split heat exchangers, and realizing complementary utilization of heat "exothermic-endothermic".

[0014] 2. Reduced heat transfer loss: Traditional split heat exchangers (such as two independent plate heat exchangers) require indirect heat transfer through "heat release side → intermediate medium (such as hot water) → heat absorption side", resulting in multiple heat losses; while the mother-daughter type transfers heat through the "face-to-face and inside-out" of the same disc, with a shorter heat transfer path and higher heat utilization efficiency.

[0015] 3. Compact and integrated design, saving space and installation costs: The space utilization rate of the mother-daughter disc structure is significantly improved, with a small footprint, making it suitable for compact workshops: The disc structure itself has the characteristic of "large heat transfer area per unit volume", and the "mother-daughter nesting" design further integrates two heat exchangers into the same main body of the equipment, resulting in a smaller overall volume.

[0016] 4. Dual-cycle independent adjustment for higher precision and stability: For different temperature control requirements of exothermic reactions (which require precise heat transfer to prevent overheating) and endothermic reactions (which require stable heat replenishment to prevent cooling), the mother-daughter structure can achieve "independent use or linkage adaptation", especially suitable for temperature-sensitive processes (such as in reactive dye reactions, where temperature fluctuations may cause dye color deviation). Linkage Mode: High-efficiency matching and coupling reaction: When exothermic reactions (such as diazotization) and endothermic reactions (such as coupling) exist simultaneously in production, the dual-cycle linkage is activated to directly utilize the exothermic energy supply, which is suitable for continuous and large-scale production (such as the continuous coupling process of reactive dyes) and maximizes energy saving effect.

[0017] 5. High overall adaptability: The equipment has a continuous heat exchange efficiency and can set the pipe length according to actual needs, thereby increasing the number of mother rings and daughter rings. Attached Figure Description

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-7 As shown, the present invention provides a technical solution: a continuous heat exchange device for reactive dye processing, including a mother heat exchange structure 1, with brackets 2 detachably installed at both ends of the mother heat exchange structure 1, the mother heat exchange structure 1 being detachably placed inside a heat exchange box 3, a plurality of nozzles 4 being equidistantly arranged on the upper wall of the heat exchange box 3, and the nozzles 4 being connected in series with each other, the plurality of nozzles 4 being able to connect with the mother heat exchange structure 1, a first outlet 6 being provided at the bottom of the left side wall of the heat exchange box 3, a plurality of second outlets 7 being provided on the upper left side wall of the heat exchange box 3, a plurality of first pipe holes being arranged along an arc in the middle of the left and right side walls of the heat exchange box 3, and a daughter heat exchange structure being detachably embedded in the middle of the mother heat exchange structure 1, the daughter heat exchange structure being able to connect with the mother heat exchange structure 1.

[0022] As a further embodiment of the present invention, the mother heat exchange structure 1 includes an outer guide ring 11, a plurality of conduits 12, a plurality of mother rings 13, a plurality of first isolation plates 14, and a plurality of adapter seats 15; the outer guide rings 11 are symmetrically arranged, and a plurality of first adapter ports 101 are symmetrically arranged on opposite sidewalls of the outer guide rings 11, the first adapter ports 101 corresponding to the first pipe holes; the outer guide rings 11 are all hollow circular ring structures, and a first delivery port 8 is provided in the middle of the upper wall of each outer guide ring 11; the two ends of the plurality of conduits 12 are respectively fixedly connected to the first adapters between the outer guide rings 11. At port 101, several mother rings 13 are circular structures with the same diameter as the outer guide ring 11. These mother rings 13 are fixedly fitted onto several guide tubes 12 and arranged between the outer guide rings 11. Second delivery ports 9 are staggered on the left and right sidewalls of the mother rings 13 near their front ends. Several first isolation plates 14 are fixedly installed inside the front end of the mother rings 13, and the first isolation plates 14 isolate the inner cavity of the mother rings 13. The first isolation plates 14 are located between the second delivery ports 9. Several adapter seats 15 are symmetrically arranged on the left sidewall of the mother rings 13, and the adapters... The seats 15 are located between a pair of conduits 12; the mother rings 13 are connected in series via the adapter pipe 16, and the two spaces within the mother rings 13 are isolated by the first isolation plate 14. The second delivery port 9 of each mother ring 13 is used for input and output respectively, causing the medium to flow along the ring and contact the through conduits 12 during flow. Simultaneously, two outer guide rings 11 are used for the input and output ends respectively, thus achieving continuous heat exchange through medium contact. The overall heat exchange efficiency can be improved by increasing the length of the conduits 12 and thus increasing the number of mother rings 13. The outer guide rings 11 can be configured... Located on the left and right sides of the heat exchange box 3, with the conduit 12 able to penetrate the first pipe hole of the heat exchange box 3 for design requirements, enabling secondary heat exchange through the heat exchange box 3. The mother ring 13 can be embedded in the heat exchange box 3 and located below the nozzle 4 for design requirements, enabling secondary heat exchange through the heat exchange box 3. The second outlet 7 is connected to the mother ring 13 and the daughter ring 51 connected in series respectively. The total heat exchange area and heat exchange efficiency of the mother heat exchange structure 1 can be improved by increasing the length of the conduit 12, directly increasing the number of mother rings 13 installed, thereby increasing the total heat exchange area and ultimately improving the heat exchange efficiency.

[0023] Medium input and flow path: The heat exchange medium (or heat exchange medium) is input through the first delivery port 8 of one of the outer guide rings 11. After the medium enters the cavity of the outer guide ring 11, it is evenly distributed into several conduits 12, flows along the conduits 12 to another outer guide ring 11, and is output from the first delivery port 8 of the outer guide ring 11. Another medium (heat exchange medium or medium to be heat exchanged) is input through the second conveying port 9 at the first end of the series-connected mother ring 13 (i.e., the second conveying port 9 of the mother ring 13 closest to one of the outer guide rings 11). Since the first isolation plate 14 divides the inner cavity of the mother ring 13 into independent arc-shaped spaces, the medium flows along the arc-shaped space after entering the mother ring 13, flows out from the other second conveying port 9 of the same mother ring 13, and then enters the next mother ring 13 through the transfer pipe 16, and finally outputs from the second conveying port 9 at the tail end of the series-connected mother ring 13.

[0024] The heat exchange process is achieved as follows: The conduit 12 penetrates the inner cavity of the mother ring 13. When the medium in the conduit 12 and the medium in the mother ring 13 flow simultaneously, they undergo direct heat conduction through the wall of the conduit 12. If the medium in the conduit 12 is exothermic (such as the high-temperature liquid after the coupling reaction of reactive dyes) and the medium in the mother ring 13 is endothermic (such as the low-temperature liquid before the condensation reaction of reactive dyes), the heat of the medium in the conduit 12 is transferred to the medium in the mother ring 13 through the conduit wall, achieving heat complementarity of "exothermic-endothermic". Conversely, if the medium in the conduit 12 is endothermic and the medium in the mother ring 13 is exothermic, heat transfer can be completed in the same way. Due to the annular structure of the mother ring 13, the flow path of the medium is extended, and the total heat exchange area is increased after several mother rings 13 are connected in series, which can realize continuous and efficient heat exchange of the medium.

[0025] Adjustment of heat exchange efficiency: If it is necessary to improve the overall heat exchange efficiency, the length of the conduit 12 can be increased. Since the mother ring 13 is fitted on the conduit 12, the number of mother rings 13 can be increased after the length of the conduit 12 is increased, thereby expanding the total heat exchange area (the more mother rings 13 there are, the larger the contact area between the medium and the conduit, and the higher the heat exchange efficiency); conversely, the length of the conduit 12 can be shortened and the number of mother rings 13 can be reduced to adapt to small-scale heat exchange needs.

[0026] To further improve the heat exchange effect, the assembled mother heat exchange structure 1 can be adapted and installed with the heat exchange box 3 to achieve a dual heat exchange mode of "primary heat exchange of duct 12-mother ring 13 plus secondary heat exchange of heat exchange box 3 spray". The specific adaptation method is as follows: Place the heat exchange box 3 horizontally, and machine a number of first pipe holes along the arc in the middle of the left and right side walls of the heat exchange box 3 (the number and position of the first pipe holes correspond one-to-one with the conduits 12). Set the two outer guide rings 11 of the mother heat exchange structure 1 on the outside of the left and right sides of the heat exchange box 3 respectively, so that the number of conduits 12 pass through the first pipe holes of the left and right side walls of the heat exchange box 3 one-to-one, ensuring that the mother ring 13 is completely embedded in the interior of the heat exchange box 3, and all mother rings 13 are located directly below the number of nozzles 4 set on the upper wall of the heat exchange box 3 (the nozzles 4 are connected in series through pipes, and spraying medium can be input).

[0027] Several second outlets 7 opened on the upper left wall of the heat exchange box 3 are respectively connected to the second conveying port 9 at the tail end of the series-connected mother ring 13 and the output port of the sub-ring 51 in the subsequent sub-heat exchange structure, so as to export the medium that has completed heat exchange in the mother ring 13 and the sub-ring 51 to the outside of the heat exchange box 3; the first outlet 6 opened at the bottom of the left side wall of the heat exchange box 3 is used to export the liquid accumulated after spraying by the nozzle 4 in the heat exchange box 3 (such as cold water / hot water for spraying), so as to realize the recycling or discharge of the spraying medium.

[0028] Achieving secondary heat exchange: Based on the primary heat exchange of the conduit 12-mother ring 13, a heat exchange medium (such as low-temperature cold water or high-temperature hot water) is sprayed into the heat exchange box 3 through the nozzle 4. The sprayed medium acts directly on the outer wall of the mother ring 13 and undergoes secondary heat exchange with the medium inside the mother ring 13. If the medium inside the mother ring 13 still needs to be further cooled, cold water can be sprayed through the nozzle 4; if the medium inside the mother ring 13 needs to be further heated, hot water can be sprayed. Thus, through the combination of primary conduction heat exchange and secondary spray heat exchange, the temperature control accuracy is further improved, adapting to the temperature-sensitive process requirements in reactive dye processing.

[0029] As a further embodiment of the present invention, the sub-heat exchange structure includes a plurality of sub-heat exchange components 5, which are detachably embedded in the mother ring 13, and the plurality of sub-heat exchange components 5 are connected in series with each other through pipes.

[0030] As a further embodiment of the present invention, the sub-heat exchange assembly 5 includes a sub-ring 51, a second partition plate 52, a few turbulence-disrupting plates 53, a pair of adapter plates 54, and bolts 55; the sub-ring 51 is a hollow circular ring structure, and the outer diameter of the sub-ring 51 is the same as the inner diameter of the mother ring 13. The sub-ring 51 is detachably embedded in the mother ring 13. A pair of third conveying ports 10 are symmetrically arranged on the inner sidewall of the sub-ring 51. Several second partition plates 52 are respectively fixedly arranged in the sub-ring 51, and the second partition plates 52 are located between the third conveying ports 10. The few turbulence-disrupting plates 53 are respectively inclinedly arranged on the inner wall of the sub-ring 51, and are arranged clockwise alternately on the upper and lower sidewalls of the sub-ring 51. A pair of adapter plates 54 are respectively symmetrically arranged on the upper and lower sidewalls of the sub-ring 51, and the adapter plates 54 are respectively fixed to the adapter seat 15 by bolts 55; the bolts 55 penetrate the adapter seat 15. A connecting plate 54 is screwed onto an adapter 15 to mount a sub-ring 51. The sub-ring 51 is embedded into the mother ring 13 for contact and engagement, enabling contact conduction between the sub-ring 51 and the mother ring 13. Simultaneously, one end of the series-connected sub-ring 51 can be used as an output end, and the other end as an input end. One end can be connected to the first conveying port 8 of the outer guide ring 11 or the second conveying port 9 of the mother ring 13. Depending on the actual conveying medium, exothermic reaction materials can be conveyed through the sub-ring 51, and endothermic reaction materials can be conveyed through the mother ring 13, achieving energy saving and energy utilization. The third conveying port 10 of the sub-ring 51 is connected in series alternately via pipes for design connection requirements. The third conveying port 10 of the sub-ring 51 can be connected to the first conveying port 8 of the outer guide ring 11 for design usage requirements, realizing the mutual utilization of heat energy from exothermic and endothermic reactions.

[0031] More specifically, the sub-heat exchange component 5 is an "auxiliary enhanced heat exchange unit" of the mother heat exchange structure 1. It is coupled with the mother ring 13 through a detachable embedding method to further improve the heat exchange efficiency and media adaptability. It utilizes the combination of exothermic and endothermic reactions to achieve energy utilization, while also transporting media at the corresponding temperature to achieve supplementation and temperature control.

[0032] Medium path within sub-ring 51: The exothermic reaction medium in reactive dye processing (such as the high-temperature reaction liquid after coupling reaction, typically 60-80℃) is input through the third conveying port 10 at the beginning of the series-connected sub-heat exchange assembly 5. After entering the arc-shaped flow channel of sub-ring 51, the medium is blocked by the second baffle 52 and flows clockwise, forming turbulence under the action of the baffle 53. After flowing through all sub-rings 51, it is output from the third conveying port 10 at the end of the series-connected sub-heat exchange assembly 5 (at this time, the medium temperature has dropped to 35-45℃, completing the exothermic process).

[0033] Medium path within the mother ring 13: The endothermic reaction medium (such as the low-temperature raw material liquid before the condensation reaction, usually at 20-30℃) in the reactive dye processing is simultaneously input through the second conveying port 9 of the mother ring 13. The medium flows along the annular flow channel of the mother ring 13 (the specific path is referred to the implementation method of the mother heat exchange structure 1), and is finally output from another second conveying port 9 of the mother ring 13.

[0034] The heat exchange process is achieved as follows: Since the outer wall of the daughter ring 51 is in close contact with the inner wall of the mother ring 13, when the exothermic medium in the daughter ring and the heat-absorbing medium in the mother ring 13 flow simultaneously, heat is directly conducted through the "outer wall of daughter ring 51 → inner wall of mother ring 13": the heat of the exothermic medium in the daughter ring 51 is transferred to the heat-absorbing medium in the mother ring 13, raising the temperature of the heat-absorbing medium to 40-50℃ (meeting the temperature requirements of the condensation reaction), while the temperature of the exothermic medium decreases (no additional cooling equipment is required), achieving "complementary utilization of heat"; compared with traditional separate heat exchangers, this process reduces the indirect heat transfer links of "exothermic medium → intermediate carrier → heat-absorbing medium", thus reducing the heat loss rate.

[0035] Port adaptation: The third delivery port 10 of the sub-ring 51 can be adjusted according to actual needs: if the heat-releasing medium has sufficient heat, the third delivery port 10 of the sub-ring 51 can be connected only to the series pipe to independently complete the heat exchange with the mother ring 13; if the heat-releasing medium has insufficient heat, the third delivery port 10 of the sub-ring 51 can be connected to the first delivery port 8 of the outer guide ring 11 through the pipe, so that the auxiliary heat exchange medium (such as hot water) in the guide tube 12 can supplement the heat to the sub-ring 51, ensuring that the temperature of the heat-absorbing medium in the mother ring 13 meets the standard.

[0036] If only a single exothermic or endothermic reaction needs to be handled, the sub-heat exchanger 5 can be removed and the mother heat exchanger structure 1 can be used alone; if a continuous, multi-step reaction needs to be handled, the sub-heat exchanger 5 can be assembled and used in series to maximize energy saving.

[0037] To further improve heat exchange accuracy, the sub-heat exchange component 5 can be adapted to the heat exchange box 3 along with the parent heat exchange structure 1. The specific coordination method is as follows: Medium output and circulation: The second row outlet 7 on the upper left side of the heat exchange box 3 is connected to the third conveying port 10 at the tail end of the sub-heat exchange assembly 5 connected in series through a pipe, so that the medium that has completed the heat release in the sub-ring 51 is discharged from the heat exchange box 3 through the second row outlet 7, and can be directly transported to the next process (such as the filtration process of reactive dyes) or recycled; at the same time, the output end of the mother ring 13 is also connected to another second row outlet 7 to ensure that the medium that has completed the heat absorption in the mother ring 13 is discharged synchronously.

[0038] Secondary heat exchange enhancement: When the nozzles 4 on the upper wall of the heat exchange box 3 spray auxiliary heat exchange medium (such as cold water or hot water) onto the mother ring 13, the outer wall of the mother ring 13 undergoes secondary heat exchange with the sprayed medium: if the temperature of the heat-absorbing medium inside the mother ring 13 is too high, it can be cooled by spraying cold water through the nozzles 4; if the temperature is too low, hot water can be sprayed to supplement the heat; this process forms a "double guarantee" with the direct heat exchange between the daughter ring 51 and the mother ring 13.

[0039] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0040] Method 1: The outer guide rings 11 in the mother heat exchange structure 1 are connected relative to each other by inserting the first adapter 101 through the conduit 12, and multiple mother rings 13 are equidistantly mounted on the conduit 12. At the same time, the second delivery ports 9 of the mother rings 13 are connected in series by the adapter 16, so that the annular spaces in the multiple mother rings 13 are connected in series, so that the medium enters from one of the second delivery ports 9 and exits from the other second delivery port 9 through the isolation of the first isolation plate 14, and achieves flow along the arc-shaped inner cavity. If the mother heat exchange structure 1 is used externally, the bracket 2 can be fitted onto both ends of the conduit 12 near the outer guide ring 11 to support the mother heat exchange structure 1; at this time, the mother ring 13 connected in series can be connected to the corresponding pipelines at both ends to transport the heat exchange medium or heat exchange medium; the first delivery port 8 of the outer guide ring 11 is connected to the pipeline to transport the heat exchange structure or heat exchange medium, so that the medium flowing in the conduit 12 and the medium flowing in the mother ring 13 can be contacted for heat exchange, and the flow velocity and heat exchange time can be extended through the mother ring 13. The number of mother rings 13 can be set according to the actual use requirements to change the heat exchange efficiency. If the mother heat exchange structure 1 is installed inside the heat exchange box 3, the outer guide ring 11 is located on the outer side of the left and right ends of the heat exchange box 3, and the conduit 12 is installed through the left and right side walls of the heat exchange box 3, so that the mother ring 13 is located inside the heat exchange box 3. Then, the two ends of the series-connected mother ring 13 are respectively connected to two of the second row outlets 7, so that the medium can be transported through the pipeline connected to the second row outlets 7. The first conveying port 8 of the outer guide ring 11 is still connected to the pipeline to transport the medium. The first conveying port 8 of one of the outer guide rings 11 is connected to the nozzle 4, so that the medium in the conduit 12, after passing through the mother ring 13 for heat exchange, is sprayed out from the nozzle 4 and contacts the outer side wall of the mother ring 13 for secondary heat absorption and heat exchange. The discharged medium is located inside the heat exchange box 3 and can be circulated or transported through the first row outlet 6 connected to the pipeline. Method 2: The sub-ring 51 in the sub-heat exchange structure can be embedded into the mother ring 13. The adapter plate 54 is fitted and matched with the adapter seat 15 on the side wall of the mother ring 13, and then fixed with bolts 55. After a single sub-ring 51 is embedded into the mother ring 13, the sub-rings 51 are connected in series through the third delivery port 10 to form a circulating and alternating arc-shaped internal cavity flow, just like the mother ring 13. The series-connected sub-rings 51 are respectively connected to another second outlet 7 as input ends and to the first delivery port 8 of one of the outer conduits 12 as input ends. This allows the exothermic reaction medium to be transported in the sub-ring 51. When the sub-ring 51 flows, the heat conduction is achieved through the contact between the sub-ring 51 and the side wall of the mother ring 13, supplementing the energy of the endothermic reaction in the mother ring 13. At the same time, the exothermic medium can flow into the conduit 12 and contact the endothermic reaction again for heat exchange, realizing energy utilization. Alternatively, the conduit 12 can be used to transport the medium alone, supplementing the energy when the exothermic energy in the sub-ring 51 is insufficient, thereby reducing external energy consumption.
