[0016] 2. Reduce heat transfer loss: The traditional separated heat exchanger (such as two independent plate heat exchangers) needs to transfer indirectly through "heat-releasing side-intermediate medium (such as hot water)-heat-absorbing side", which has multiple heat losses; while the sub-mother ring structure transfers heat through "face-to-face, inside and outside" of the same disc, the heat transfer path is short, and the heat utilization efficiency is higher.

[0017] 3. Compact integrated design, saving space and installation cost: The space utilization of the sub-mother ring structure is significantly improved, the land area is small, and it is suitable for compact workshops: the disc structure itself has the characteristics of "large heat transfer area per unit volume", and the "sub-mother nesting" design further integrates two heat exchangers in the same equipment main body, and the overall volume is small.

[0018] 4. Double-circulation independent adjustment, higher precision and stability: According to the different temperature control requirements of heat-releasing reaction (which needs to remove heat accurately to prevent overheating) and heat-absorbing reaction (which needs to supply heat stably to prevent temperature drop), the sub-mother structure can realize "independent use or linkage adaptation", especially suitable for temperature-sensitive processes (such as in the active dye reaction, temperature fluctuation may cause dye color deviation);

[0019] Linkage mode: efficient matching of coupled reactions: when there are heat-releasing reactions (such as diazotization) and heat-absorbing reactions (such as coupling) in production at the same time, open the double-circulation linkage, directly use the heat-releasing energy, suitable for continuous and large-scale production (such as the continuous coupling process of active dyes), and maximize the energy saving effect.

[0020] 5. High overall adaptability: The continuous heat exchange efficiency of the equipment can be set according to the actual demand, and the length of the guide pipe is increased, and the number of mother rings and sub-rings is increased. BRIEF DESCRIPTION OF DRAWINGS

[0031] As a further scheme of the present application, the female heat exchange structure 1 comprises a pair of outer guide rings 11, a plurality of guide pipes 12, a plurality of female rings 13, a plurality of first isolation plates 14 and a plurality of adapter seats 15; the pair of outer guide rings 11 are respectively arranged symmetrically, and the outer guide rings 11 are symmetrically provided with a plurality of first adapter interfaces 101 on the opposite side walls, the first adapter interfaces 101 correspond to the first pipe holes, the pair of outer guide rings 11 are hollow annular structures, and the upper walls of the outer guide rings 11 are provided with first conveying ports 8 in the middle, the two ends of the plurality of guide pipes 12 are respectively fixedly connected to the first adapter interfaces 101 between the outer guide rings 11, the plurality of female rings 13 are annular structures with the same diameter as the outer guide rings 11, the plurality of female rings 13 are fixedly sleeved on the plurality of guide pipes 12 and arranged between the outer guide rings 11, the left and right side walls of the plurality of female rings 13 close to the front ends are respectively located above and below the second conveying ports 9, the plurality of first isolation plates 14 are fixedly arranged at the front ends of the female rings 13, and the first isolation plates 14 first isolate the inner cavities of the female rings 13, the first isolation plates 14 are located between the second conveying ports 9, and the plurality of adapter seats 15 are respectively and symmetrically arranged on the left side walls of the female rings 13 and located between the pair of guide pipes 12; the female rings 13 are connected in series through the adapter pipes 16, the inner space of the female rings 13 is isolated by the first isolation plates 14, and then the second conveying ports 9 of each female ring 13 are respectively used for input and output, so as to make the medium flow along the ring and contact the penetrating guide pipes 12 in the flow, at the same time, the two outer guide rings 11 are respectively used for the input and output ends, so as to realize the continuous heat exchange of the medium contact; the overall heat exchange efficiency can be increased by increasing the length of the guide pipes 12 and then increasing the number of the female rings 13, the outer guide rings 11 can be arranged on the left and right sides of the heat exchange box 3, the guide pipes 12 can penetrate the first pipe holes of the heat exchange box 3, and the heat exchange box 3 can be used for secondary heat exchange according to design requirements, the female rings 13 can be embedded in the heat exchange box 3 and located below the spray head 4, and the heat exchange box 3 can be used for secondary heat exchange according to design requirements, the second discharge ports 7 are respectively connected with the female rings 13 and the female rings 13 connected in series, and the total heat exchange area and the heat exchange efficiency of the female heat exchange structure 1 can be increased by increasing the length of the guide pipes 12, directly increasing the installation number of the female rings 13, then increasing the total heat exchange area, and finally improving the heat exchange efficiency.

[0032] Medium input and flow path: the heat exchange medium to be exchanged is input through the first conveying port 8 of one of the outer guide rings 11, and after the medium enters the cavity of the outer guide ring 11, it is evenly distributed into a plurality of guide pipes 12, flows along the guide pipes 12 to the other outer guide ring 11, and is output from the first conveying port 8 of the outer guide ring 11;

[0033] Another path of medium (heat exchange medium or medium to be heat exchanged) is inputted through the first end second delivery port 9 of the mother ring 13 (i.e. the second delivery port 9 of the mother ring 13 closest to one of the outer guide rings 11), and since the first isolation plate 14 separates the inner cavity of the mother ring 13 into independent arc-shaped spaces, the medium flows along the arc-shaped spaces after entering the mother ring 13, flows out from another second delivery port 9 of the same mother ring 13, enters the next mother ring 13 through the adapter pipe 16, and is finally outputted from the tail end second delivery port 9 of the series-connected mother rings 13.

[0034] Heat exchange process: The conduit 12 penetrates the inner cavity of the mother ring 13, and when the medium in the conduit 12 and the medium in the mother ring 13 flow at the same time, the two conduct heat directly through the pipe wall of the conduit 12: if the medium in the conduit 12 is an exothermic medium (such as high-temperature liquid after the coupling reaction of reactive dyes), and the medium in the mother ring 13 is an endothermic medium (such as 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 pipe wall, realizing heat complementation of "exothermic-endothermic"; conversely, if the medium in the conduit 12 is an endothermic medium, and the medium in the mother ring 13 is an exothermic medium, heat transfer can be completed in the same way; since the annular structure of the mother ring 13 prolongs the medium flow path, and the total heat exchange area is increased after the series connection of the several mother rings 13, continuous and efficient heat exchange of the medium can be realized.

[0035] 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, and since the mother ring 13 is sleeved on the conduit 12, the length of the conduit 12 can be increased to increase the number of mother rings 13, thereby expanding the total heat exchange area (the more the number of mother rings 13, the greater the contact area of the medium with 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 requirements.

[0036] To further improve the heat exchange effect, the assembled mother heat exchange structure 1 can be installed with the heat exchange tank 3 to realize a double heat exchange mode of "conduit 12-mother ring 13 primary heat exchange plus heat exchange tank 3 secondary heat exchange", and the specific adaptation mode is as follows:

[0037] The heat exchange tank 3 is placed horizontally, a plurality of first pipe holes (the number and position of the first pipe holes correspond to the conduit 12 one by one) are processed along an arc in the middle of the left and right side walls of the heat exchange tank 3, the two outer guide rings 11 of the mother heat exchange structure 1 are arranged outside the left and right sides of the heat exchange tank 3 respectively, a plurality of conduits 12 are inserted through the first pipe holes of the left and right side walls of the heat exchange tank 3 one by one, the mother ring 13 is completely embedded in the inside of the heat exchange tank 3, and all the mother rings 13 are located directly below a plurality of spray heads 4 arranged on the upper wall of the heat exchange tank 3 (the spray heads 4 are relatively connected in series through pipes, and a spraying medium can be inputted).

[0038] The second discharge outlets 7 formed in the upper wall of the left end of the heat exchange box 3 are respectively connected with the tail end second conveying ports 9 of the mother ring 13 and the output ports of the sub rings 51 in the subsequent sub heat exchange structures, for guiding the media in the mother ring 13 and the sub rings 51, which have completed heat exchange, out of the heat exchange box 3; and the first discharge outlet 6 formed in the bottom of the left side wall of the heat exchange box 3 is used for guiding the accumulated liquid (such as cold water / hot water for spraying) after the spraying of the spray head 4 in the heat exchange box 3, so as to realize the recycling or discharge of the spraying medium.

[0039] Secondary heat exchange: on the basis of the "conduit 12-mother ring 13 primary heat exchange", the heat exchange medium (such as low-temperature cold water or high-temperature hot water) is sprayed into the heat exchange box 3 by the spray head 4, and the spraying medium directly acts on the outer wall of the mother ring 13 and performs secondary heat exchange with the medium in the mother ring 13: if the medium in the mother ring 13 still needs to be further cooled, cold water can be sprayed by the spray head 4; if the medium in the mother ring 13 needs to be further heated, hot water can be sprayed, so as to further improve the temperature control accuracy through the combination of "primary conduction heat exchange and secondary spraying heat exchange", and adapt to the process requirements sensitive to temperature in the active dye processing.

[0040] As a further scheme of the present application, the sub heat exchange structure includes a plurality of sub heat exchange assemblies 5, and the plurality of sub heat exchange assemblies 5 are respectively detachably embedded in the mother ring 13 and are connected in series through pipes.

[0041] As a further scheme of the present application, the sub heat exchange assembly 5 comprises a sub ring 51, a second partition plate 52, a plurality of spoiler plates 53, a pair of adapter plates 54 and bolts 55; the sub ring 51 is a hollow annular structure, and the outer wall diameter of the sub ring 51 is the same as the inner wall diameter of the mother ring 13, the sub ring 51 is detachably embedded in the mother ring 13, and a pair of third conveying ports 10 are symmetrically arranged on the inner side wall of the sub ring 51; a plurality of second partition plates 52 are fixedly arranged in the sub ring 51, and the second partition plates 52 are located between the third conveying ports 10; a plurality of spoiler plates 53 are obliquely arranged on the inner wall of the sub ring 51, and are arranged on the upper and lower side walls of the sub ring 51 in a clockwise staggered manner; a pair of adapter plates 54 are symmetrically arranged on the upper and lower side walls of the sub ring 51, and the adapter plates 54 are fixed with the adapter seats 15 through the bolts 55; the sub ring 51 is arranged by penetrating the adapter plates 54 through the bolts 55 and being screwed on the adapter seats 15, and the sub ring 51 is embedded in the mother ring 13 to contact and fit, so that the contact conduction between the sub ring 51 and the mother ring 13 can be realized, and the series-connected sub ring 51 can be used as an output end and an input end at the same time, one end of which is connected with the first conveying port 8 of the outer guide ring 11 or the second conveying port 9 of the mother ring 13; according to the actual conveying medium, the reaction exothermic raw material can be conveyed through the sub ring 51, and the reaction endothermic raw material can be conveyed through the mother ring 13, so that the energy saving and energy utilization effects can be realized; the third conveying ports 10 of the sub ring 51 are alternately connected in series through pipelines, which are used for design connection requirements; the third conveying ports 10 of the sub ring 51 can be connected with the first conveying ports 8 of the outer guide ring 11, which are used for design use requirements, so that the heat energy utilization of the exothermic reaction and the endothermic reaction can be realized.

[0042] More specifically, the sub heat exchange assembly 5 is an "auxiliary reinforced heat exchange unit" of the mother heat exchange structure 1, which is detachably embedded with the mother ring 13 to further improve the heat exchange efficiency and the medium adaptation flexibility, combines the exothermic reaction in the reaction and the endothermic reaction in the reaction to achieve energy utilization, and can also convey the corresponding temperature medium to achieve temperature compensation and control.

[0043] The medium path in the sub ring 51: the exothermic reaction medium in the active dye processing (such as high-temperature reaction liquid after coupling reaction, the temperature is usually 60-80℃) is input through the first end third conveying port 10 of the series-connected sub heat exchange assembly 5, the medium enters the arc-shaped flow channel of the sub ring 51, is blocked by the second partition plate 52 and flows in the clockwise direction, and forms turbulent flow under the action of the spoiler plates 53; after flowing through all the sub rings 51, the medium is output from the tail end third conveying port 10 of the series-connected sub heat exchange assembly 5 (at this time, the medium temperature has been reduced to 35-45℃, and the exothermic reaction is completed).

[0044] Medium path in mother ring 13: the endothermic reaction medium in the process of reactive dye processing (such as low-temperature raw material solution before condensation reaction, usually at 20-30°C) is input through the second delivery port 9 of the mother ring 13, and the medium flows along the annular flow channel of the mother ring 13 (for details, refer to the implementation of the mother heat exchange structure 1), and finally is output from the other second delivery port 9 of the mother ring 13.

[0045] Heat exchange process: due to the close fit of the outer wall of the sub-ring 51 and the inner wall of the mother ring 13, when the exothermic medium in the sub-ring and the endothermic medium in the mother ring 13 flow at the same time, heat is directly conducted through the "outer wall of the sub-ring 51→ inner wall of the mother ring 13": the heat of the exothermic medium in the sub-ring 51 is transferred to the endothermic medium in the mother ring 13, so that the temperature of the endothermic medium is raised to 40-50°C (satisfying the temperature requirement of condensation reaction), while the temperature of the exothermic medium is lowered (without the need for additional cooling equipment to lower the temperature), realizing "complementary use of heat"; compared with the traditional separate heat exchanger, this process reduces the indirect heat transfer link of "exothermic medium→ intermediate carrier→ endothermic medium", and reduces the heat loss rate.

[0046] Port adaptation: the third delivery port 10 of the sub-ring 51 can be adjusted according to actual needs: if the exothermic medium has sufficient heat, the third delivery port 10 of the sub-ring 51 can be connected only with the serial pipeline, and the heat exchange with the mother ring 13 is completed independently; if the exothermic medium has insufficient heat, the third delivery port 10 of the sub-ring 51 can be connected with the first delivery port 8 of the outer guide ring 11 through a pipeline, so that the auxiliary heat exchange medium (such as hot water) in the guide pipe 12 supplements heat to the sub-ring 51, ensuring that the temperature of the endothermic medium in the mother ring 13 meets the standard.

[0047] If only a single exothermic or endothermic reaction needs to be processed, the sub-heat exchange assembly 5 can be removed, and the mother heat exchange structure 1 can be used alone; if continuous, multi-step reactions need to be processed, the sub-heat exchange assembly 5 can be assembled and used in series, maximizing energy-saving effect.

[0048] In order to further improve the heat exchange precision, the sub-heat exchange assembly 5 can be adapted with the mother heat exchange structure 1 together with the heat exchange box 3, and the specific coordination mode is as follows:

[0049] Medium output and circulation: the second row of outlets 7 on the left end of the upper wall of the heat exchange box 3 are connected with the tail end third delivery port 10 of the serially connected sub-heat exchange assembly 5 through a pipeline, so that the medium in the sub-ring 51 that has completed exothermic reaction is guided out of the heat exchange box 3 through the second row of outlets 7, and can be directly delivered to the next process (such as the filtration process of reactive dye) or recycled; at the same time, the output end of the mother ring 13 is also connected with another second row of outlets 7, ensuring that the medium in the mother ring 13 that has completed endothermic reaction is guided out at the same time.

[0050] Secondary heat exchange strengthening: when the spray head 4 on the upper wall of the heat exchange box 3 sprays the auxiliary heat exchange medium (such as cold water or hot water) to the mother ring 13, the outer wall of the mother ring 13 performs secondary heat exchange with the sprayed medium: if the temperature of the heat-absorbing medium in the mother ring 13 is too high, cold water can be sprayed through the spray head 4 to lower the temperature; 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.

[0051] The detailed connection means is a technology known in the art, and the working principle and process are described below.

[0054] If the mother heat exchange structure 1 is used externally, the bracket 2 can be sleeved on both ends of the pipe 12 close to the outer guide ring 11 to support the mother heat exchange structure 1; at this time, the series-connected mother ring 13 can connect the series-connected mother ring 13 at both ends to the pipeline conveying the heat-exchanged medium or the heat exchange medium; the first delivery port 8 of the outer guide ring 11 is connected to the pipeline conveying the heat-exchanged structure or the heat exchange medium, so that the medium flowing in the pipe 12 and the medium flowing in the mother ring 13 are in contact and heat exchange, and the flow speed and heat exchange time can be prolonged by the mother ring 13, and the number of mother rings 13 can be set according to the actual use demand to change the heat exchange efficiency;
