[0064] The embodiments of the present application disclose a membrane separation integrated device, please refer to Figures 1 to 13 , Figure 22The membrane separation integrated device comprises a membrane separation device 10 and a plurality of auxiliary devices for providing membrane separation conditions for the membrane separation device 10; the membrane separation device 10 and the plurality of auxiliary devices are integrated into an integrated device, and the plurality of auxiliary devices comprise at least one of a preheater 20, a heater 30 and a vacuum condenser 40, so that the length of the pipeline connection between the auxiliary devices and the membrane separation device 10 can be reduced, the liquid flow resistance in the pipeline can be reduced, the heat energy loss is small, and the miniaturization of the membrane separation integrated device is facilitated.

[0065] In an embodiment, referring to Figures 1 to 4 The plurality of auxiliary devices comprise the preheater 20, the heater 30 and the vacuum condenser 40; the preheater 20 is connected to the heater 30 and the material cavity of the membrane separation device 10, and is used for preheating the material; the heater 30 is connected to the material cavity of the membrane separation device 10, and is used for heating the material; and the vacuum condenser 40 is connected to the vacuum cavity of the membrane separation device 10, and is used for driving the membrane separation of the membrane separation device 10; wherein the preheater 20 and the heater 30 are respectively attached to the outer wall of the membrane separation device 10, and the permeation side of the membrane separation device 10 is directly connected to the vacuum condenser 40 as a whole. The preheater 20, the heater 30 and the shell structure of the membrane separation device 10 are connected by the communication pipe 50 to serially connect the material flow paths, thereby forming a high-efficiency integrated membrane separation integrated device.

[0066] It can be understood that, since the preheater 20 and the heater 30 are integrated on the membrane separation device 10, the preheater 20 and the heater 30 can utilize the heat emitted by the membrane separation device 10 to preheat or heat-insulate the material in the preheater 20 and the heater 30, thereby saving energy.

[0067] The vacuum degree of the permeation side of the membrane separation device 10 has a crucial influence on the membrane separation efficiency, and the longer the pipeline between the membrane separation device 10 and the vacuum condenser 40, the worse the vacuum degree of the permeation side of the membrane separation device 10, thereby reducing the membrane dehydration efficiency. Since the permeation side of the membrane separation device 10 is directly connected to the vacuum condenser 40 as a whole, the travel loss of the pipeline connection can be reduced, the vacuum degree of the permeation side of the membrane separation device 10 can be ensured to be good, and the vacuum degree loss caused by the pipeline connection can be avoided.

[0068] The membrane separation integrated device of the embodiment solves the problems of high heat dissipation and poor vacuum effect in the system of the membrane separation integrated device.

[0069] Specifically, the shell structure of the membrane separation device 10 is provided with a first material joint 11 and a second material joint 12, one of the first material joint 11 and the second material joint 12 is a material input port, and the other is a material output port. The material passes through the preheater 20, the heater 30, the membrane separation device 10 and the preheater 20 in turn, and is connected between the functional modules through the communication pipe 50. By sharing the shell and reducing the length of the system pipeline connection, the flow loss and heat dissipation of the material between the pipelines are reduced, the system heat is fully utilized, and the energy consumption of the membrane separation equipment is reduced.

[0070] In the embodiment, the shell structure of the membrane separation device 10 shares the intermediate shell with the preheater 20. The shell structure of the membrane separation device 10 conducts the heat energy lost by the shell structure to heat the material raw material in the preheater 20. At the same time, the heat loss of the membrane separation device 10 and the preheater 20 can be reduced. Further, the shell structure of the membrane separation device 10 shares the intermediate shell with the heater 30. The material in the shell structure of the membrane separation device 10 exchanges energy with the material in the shell structure through the intermediate shell, and the energy is not dissipated to the outside. At the same time, the heat loss of the membrane separation device 10 and the heater 30 can be reduced.

[0071] According to the "Industrial Equipment and Pipeline Heat Insulation Engineering Design Specification", the allowable heat loss of the equipment pipeline is 94W / m 2 when the temperature is 125℃. That is, the allowable heat loss of the equipment pipeline insulation layer is 94W / m 2 . The shell structure of the membrane separation device 10 shares the intermediate shell 1m 2 with the preheater 20. The shell structure of the membrane separation device 10 shares the intermediate shell 1m 2 with the heater 30. The system saves DN25 pipeline 20m, and energy saving calculation is carried out.

[0072] The equipment reduces the dissipation area by 2m 2 for the shell structure of the membrane separation device 10, and by 1m 2 for the preheater 20 and the heater 30 respectively. Therefore, the reduced loss energy is Q1=(2+1+1)×94=376(W).

[0073] The pipeline reduces the dissipation area by 3.14×34×20×10 -3 =2.14m 2 for the shell structure of the membrane separation device 10. Therefore, the reduced loss energy is Q2=2.14×94=201.16(W).

[0074] According to the annual driving time of the equipment of 8000h, the system can save energy: (376+201.16)×8000×10 -3 =4617.28(kW.h).

[0075] In the embodiment, the permeation vapor separated by the membrane separation device 10 directly enters the vacuum condenser 40 connected with the membrane separation device 10 for cooling, and the permeation vapor does not need to be transmitted through a pipeline for cooling, which reduces the resistance along the pipeline, reduces the energy consumption of the vacuum pump, and improves the vacuum degree of the vacuum side of the membrane tube, thereby improving the dehydration efficiency of the membrane separation device 10; the remaining permeation vapor after volume reduction is extracted by the vacuum pump through the first vacuum joint 41.

[0076] According to the vacuum technology basic theory and experimental data verification, it is shown that the length and cross-sectional area of the vacuum pipeline have important influence on the pressure difference between the membrane separation device 10 and the vacuum condenser 40. The following is explained: Generally, the vacuum cavity of the vacuum condenser 40 is connected to the vacuum pump through a pipeline. The flow resistance is the result of external friction between gas molecules and wall surface and internal friction or viscosity between gas molecules. The flow resistance is shown in the form of pressure difference and volume flow rate or suction speed loss. In vacuum technology, the reciprocal of the flow resistance W, that is, the conductance L or conductance C of the pipeline, is used instead of the flow resistance W. The conductance has the unit of volume flow rate, and is usually expressed as [ls -1 ] or [m 3 h -1 ]. The membrane permeation gasification (vapor permeation) dehydration permeation side pressure is in the range of 10-1000 Pa (A), which belongs to low vacuum, is mainly viscous flow, also known as continuous flow, and is in a laminar flow state during normal operation of the device. In the case of laminar flow, the conductance calculation formula of the circular pipeline is:

[0077] wherein, l represents the length of the pipeline [cm]; d represents the diameter of the pipeline [cm]; P represents the pressure [Pa]; and C represents the conductance [ls -1 ].

[0078] It can be known from the above formula that, in the vacuum system, the cross section and length of the pipeline greatly affect the conductance of the circular pipeline. According to the basic equation of vacuum technology:

[0079] S1 is the suction speed (ls -1 ) at the outlet of the container to be extracted, and S2 is the suction speed (ls -1 ) at the outlet of the container to be extracted.

[0080] It can be known from the formula that, when the conductance is much smaller than the suction speed of the vacuum pump, that is, U << S2, then S1 ≈ U1, that is, the maximum suction speed of the container can only be equal to the conductance of the pipeline. In this case, it is ineffective to use a vacuum pump with a large suction speed to increase the effective speed. Similarly, when the conductance is much larger than the suction speed of the vacuum pump, that is, U >> S2, then S1 ≈ S2, and in this case, the suction speed of the container is mainly determined by the suction speed of the vacuum pump. At this time, if a vacuum pump with a large suction speed is used, the effective suction speed of the container can be significantly improved.

[0081] In summary, the vacuum condenser 40 is directly connected to the permeation side of the membrane separation device 10 without pipeline connection, which can reduce the pumping speed of the vacuum pump, thereby reducing energy consumption, and at the same time, a better vacuum effect can be obtained on the permeation side of the membrane separation device 10.

[0082] In the embodiment, the membrane separation device 10 is further provided with a first heating joint 13 and a second heating joint 14, one of which is a heating medium inlet and the other is a heating medium outlet. By controlling the flow of the heating medium of the first heating joint 13 and the second heating joint 14, the heat supplement effect in the membrane separation device 10 can be flexibly controlled.

[0083] Further, the heater 30 is provided with a first heat supply joint 31 and a second heat supply joint 32, one of which is a heating medium input port and the other is a heating medium output port. By controlling the flow of the heating medium of the first heat supply joint 31 and the second heat supply joint 32, the initial temperature of the material entering the membrane separation device 10 for dehydration can be flexibly controlled.

[0084] Further, the vacuum condenser 40 is provided with a first vacuum joint 41, a first cooling joint 42 and a second cooling joint 43, the first vacuum joint 41 is connected to the vacuum pump in communication, and the first cooling joint 42 and the second cooling joint 43 are respectively the cooling medium inlet and outlet of the vacuum condenser 40. By controlling the flow of the cooling medium of the first cooling joint 42 and the second cooling joint 43, the vacuum degree of the vacuum side of the vacuum condenser 40 can be flexibly controlled, thereby improving the membrane separation effect of the membrane separation device 10.

[0085] In another embodiment, please refer to Figures 5 to 7 The plurality of auxiliary devices include a preheater 20 and a heater 30; the preheater 20 is in communication with the heater 30 and is used for preheating the material, and the heater 30 is in communication with the material cavity of the membrane separation device 10 and is used for heating the material; wherein the preheater 20 and the heater 30 are respectively attached to the outer wall of the membrane separation device 10.

[0086] It can be understood that, since the preheater 20 and the heater 30 are integrated on the membrane separation device 10, the preheater 20 and the heater 30 can utilize the heat emitted by the membrane separation device 10 to preheat or heat preservation the material in the preheater 20 and the heater 30, thereby saving energy.

[0087] In the embodiment, the preheater 20 and the heater 30 are respectively attached to the upper and lower sides or the left and right sides of the membrane separation device 10 and share the outer wall plate with the membrane separation device 10, so that the heat dissipated by the membrane separation device 10 can be maximally utilized, and meanwhile, the heat preservation effect of the inner cavity of the membrane separation device 10 can be improved; the space is fully utilized and the shell is shared through compact arrangement, thereby saving the equipment cost.

[0088] In another embodiment, referring to Figure 12 and Figure 13 , the auxiliary devices include the vacuum condenser 40; the vacuum condenser 40 is connected with the vacuum cavity of the membrane separation device 10 and is used for driving the membrane separation of the membrane separation device 10; wherein the permeation side of the membrane separation device 10 is directly connected with the vacuum condenser 40 as a whole.

[0089] It can be understood that, since the permeation side of the membrane separation device 10 is directly connected with the vacuum condenser 40 as a whole, the stroke loss of the pipeline connection can be reduced, the vacuum degree of the permeation side of the membrane separation device 10 can be ensured to be good, and the vacuum degree loss caused by the pipeline connection can be avoided.

[0090] In the embodiment, the heater and the preheater are not arranged, and the membrane separation integrated equipment can be used for the vaporization and permeation project; the material after preheating is led to the independent vaporizer 60 and then to the membrane separation device 10, or the material from the gas phase is directly led to the membrane separation device 10.

[0092] The membrane separation integrated equipment of the embodiment does not need to arrange the heater, and can be used for the vaporization and permeation project; the material after preheating is led to the independent vaporizer 60 and then to the membrane separation device 10.

[0093] It can be understood that, since the preheater 20 is integrated on the membrane separation device 10, the preheater 20 can utilize the heat emitted by the membrane separation device 10 to preheat or heat preserve the material in the preheater 20, thereby saving energy.

[0094] Since the permeation side of the membrane separation device 10 is directly connected with the vacuum condenser 40 as a whole, the stroke loss of the pipeline connection can be reduced, the vacuum degree of the permeation side of the membrane separation device 10 can be ensured to be good, and the vacuum degree loss caused by the pipeline connection can be avoided.

[0095] Specifically, the preheater 20 is attached to the upper side, lower side, left side or right side of the membrane separation device 10, and shares the outer wall plate with the membrane separation device 10, so as to maximize the use of the heat dissipated by the membrane separation device 10. At the same time, it can also increase the insulation effect of the inner cavity of the membrane separation device 10.
