Description

Technical Field

[0001] The invention relates to the field of steel paper production, and in particular to a continuous steel paper production system. Background Art

[0002] Steel paper is a special type of paper. Currently, it mainly uses environmentally friendly natural cellulose and its derivatives as raw materials. The base paper is obtained by gelling and compounding the cellulose, and then the steel paper base paper is stacked to obtain modified processed paper.

[0003] Usually, zinc chloride solution is used for gelling and compounding, and desalting treatment is required after gelling. The traditional method is to transfer the obtained raw steel paper to multiple desalting tanks with decreasing specific gravity or concentration of zinc chloride solution. For example, Chinese patent application CN 103103867 A discloses a steel paperboard and its production process, wherein the desalting process is carried out in at least 10 desalting tanks, and the specific gravity of zinc chloride solution in each desalting tank is: 1.8, 1.5, 1.2, 1.0, 0.8, 0.5, 0.25, 0.15, 0.10 and 0.05. The processing time of each desalting tank is about 1 hour, and the whole desalting process takes more than 10 hours, or even about 1 day. At the same time, due to the need to transfer between different desalting tanks, the workload is increased, which greatly affects the efficiency of steel paper production. Therefore, it is necessary to improve the production efficiency of steel paper, especially to improve the desalting treatment efficiency after zinc chloride gelling treatment.

[0035] Example

[0036] like Figure 1 As shown, the exemplary continuous steel paper production system of the present invention includes a pretreatment module 100, a base paper forming module 200, a gelling and pressing module 300, an aging module 400, a desalination module 500 and a drying module 600. The desalination module 500 is connected to the pretreatment module 100 through a pipeline.

[0037] Figure 2The structure of the pretreatment module 100 is shown as an example, which includes a reaction tank 110, a stirring component 120, a heating component 130, a dopamine solution storage tank 140 and a dopamine solution introduction pump 150. The reaction tank 110 can be in the shape of a tank body, wherein the dopamine solution storage tank 140 and the dopamine solution introduction pump 150 are optional devices. The raw material fiber is added into the tank body, and the dopamine solution in the dopamine solution storage tank 140 can be introduced into the reaction tank 110 by, for example, the introduction pump 150. In the reaction tank 110, the fiber and dopamine are fully mixed by the stirring component 120, and if necessary, an appropriate amount of water is added through a water pipe to adjust the fiber and / or dopamine concentration. The stirring component 120 is configured to be able to stir at a speed of 50-2000 rpm. For example, the rotation speed is 100, 200, 300, 400, 500, 600, 800, 1000, 1200, 1400, 1600, 1800 rpm. The heating assembly 130 can be disposed on the side or bottom of the reaction tank 110 to maintain the temperature in the reaction tank at 40-80°C.

[0038] Figure 3 The structure of the base paper forming module 200 is shown as an example, and its structure is not particularly limited, and any structure known in the art can be adopted. For example, it includes a beater 210, a pulping box 220, a purification device 230 and a roller assembly 240. The slurry obtained from the pretreatment module 100 is pumped into the beater 210 through a pipeline and a pump. Beating is performed in the beater 210 to increase the flexibility and interweaving of the fibers, and the beating degree is controlled to be 15-25° SR and the wet weight is 8-18g. The beater 210 can be any device known in the art, including a disc refiner, a conical refiner, etc.

[0039] After beating, the slurry is passed through pipes and pumps to enter the slurry preparation box 220. When preparing the slurry in the slurry preparation box 220, the solid content of the slurry is diluted to 40-60% by weight. Next, it enters the purification device 230 for purification to remove fine impurities and particles. The purification device 230 can be of any type known in the art, including a sedimentation tank, a filter device, etc. Among them, the sedimentation tank uses gravity to precipitate impurities in the slurry to the bottom, and then extracts the upper slurry. The filter device uses filter cloth, filter screen or other filter media to intercept impurities. The filter medium is known in the art and includes chitosan adsorbent, zeolite, etc.

[0040] The downstream of the purification device 230 is connected to the roller pressing assembly 240 through a pipeline and a pump, which includes a dewatering device 241, a pressing device 242 and a wet machine 243. First, the pulp enters the dewatering device 241 through a pipeline, and the moisture in the net is removed by vacuum to form wet paper. Then it is transferred to the pressing device 242 to further remove moisture. After pressing, the paper is transferred from the wet net to the wet machine 243, where it is dried by heat transfer, and then dried by hot air to form base paper.

[0041] Figure 4 The structure of the glue pressing module 300 is shown as an example, and its structure is not particularly limited, and any structure known in the art can be adopted. For example, it includes a glue tank 310 and a pressing device 320. The glue tank 310 contains zinc chloride solution and includes multiple groups of transmission rollers 311. Each group of transmission rollers 311 moves a layer of base paper from one side of the glue tank 310 to the other side, so that each base paper is glued separately. The pressing device 320 includes a pressure roller group 321 composed of two synchronously rotating rollers, and the gap between the two rollers can be adjusted as needed. Optionally, a heating device 322 is set on one side of the pressure roller group to heat the pressure roller group 321.

[0042] The structure of the aging module 400 of the present invention is not particularly limited in its specific structure. As long as it can achieve the purpose of performing aging treatment at 20-40°C for 30-120 minutes, any structure known in the art can be adopted. For example, it can include an aging furnace and a conveying roller group, or an aging room. The aging module performs aging treatment on the steel paper by placing the steel paper in a high temperature environment and treating the steel paper at high temperature. The aging module can provide high temperature conditions for further denaturation of cellulose in the steel paper, so that the cellulose reaction inside the steel paper is more uniform.

[0043] Figure 5 , Figure 6 The structure of an exemplary desalination module (intermittent type) is shown, which includes a desalination tank 510 and an oxygen storage tank 520. An anode 511 and a cathode 512 are arranged on opposite sides of the desalination tank 510. A first cation exchange membrane 513, an anion exchange membrane 514, and a second cation exchange membrane 515 are sequentially arranged in the desalination tank 510 along the direction from the anode 511 to the cathode 512, thereby dividing the desalination tank 510 into an oxygen enrichment zone 516 between the anode 511 and the first cation exchange membrane 513, a salt enrichment zone 517 between the first cation exchange membrane 513 and the anion exchange membrane 514, a steel paper treatment zone 518 between the anion exchange membrane 514 and the second cation exchange membrane 515, and a hydrogen enrichment zone 519 between the second cation exchange membrane 515 and the cathode 512. The intervals between the exchange membranes are not limited and can be any intervals. For example, the intervals between the exchange membranes are equal, so that the enrichment zones of various components are equal in space. The spacing between the exchange membranes may also be unequal, for example, the steel paper treatment area has a larger space, while the other areas have a smaller space. Figure 5 and Figure 6 The above is merely an example of the uniform arrangement of the exchange membranes in the desalination tank 510. The edges of the exchange membranes are usually sealed with the side walls of the desalination tank, so that the channels are relatively independent. Figure 5 and Figure 6In the case of, three sides of each exchange membrane are respectively sealed and combined with the inner surface of the desalination tank. Here, the cation exchange membrane (including the first cation exchange membrane and the second cation exchange membrane) refers to a membrane that only allows cationic zinc ions to pass through, while anions cannot pass through. Similarly, the anion exchange membrane refers to a membrane that only allows anions such as chloride ions to pass through, while cations cannot pass through.

[0044] In certain embodiments, the desalting tank 510 of the present invention further includes a water inlet and a water outlet. In an intermittent system, the desalting tank may be provided with a water inlet and a water outlet, or may not be provided with a water inlet and a water outlet. In a continuous production system, the desalting tank 510 includes a water inlet and a plurality of water outlets, and the steel paper is moved along the water flow direction in the steel paper processing area 518 by a rotating roller. The setting of the rotating roller is not limited and can be freely arranged by those skilled in the art as needed. Usually, a rotating roller is set at the water inlet end of the desalting tank 510 to control the moving direction and moving mode of the steel paper, such as horizontal movement or vertical movement. At the water outlet of the desalting tank 510, a rotating roller is set as a power roller to control the moving speed of the steel paper.

[0045] In the exemplary continuous production system of the present invention, each exchange membrane divides the desalination tank 510 into an oxygen enrichment channel between the anode 511 and the first cation exchange membrane 513, a salt enrichment channel between the first cation exchange membrane 513 and the anion exchange membrane 514, a steel paper processing channel between the anion exchange membrane 514 and the second cation exchange membrane 515, and a hydrogen enrichment channel between the second cation exchange membrane 515 and the cathode 512. Each channel allows water to pass through. In certain embodiments, there is one water inlet, and water is allowed to enter different channels through the water inlet. The number of water outlets can be one, and preferably the water outlets include a plurality of outlets, which at least include a water outlet corresponding to the steel paper conveying channel, optionally, further include a water outlet corresponding to the salt enrichment channel, and further preferably, also include a water outlet corresponding to the oxygen enrichment channel and a water outlet corresponding to the hydrogen enrichment channel.

[0046] A pipeline is provided in the oxygen enrichment area 516 to communicate with the oxygen storage tank 520. Optionally, a valve switch is provided on the pipeline to control the circulation of oxygen. The other end of the oxygen storage tank 520 is connected to the pretreatment module 100 through a pipeline. Similarly, a control switch is provided on the pipeline to control the speed or amount of oxygen entering the pretreatment module 100. If necessary, a pipeline pump is further provided on the pipeline to promote the entry of oxygen into the pretreatment module 100. The oxygen is collected and introduced into the pretreatment module 100 for recycling, which promotes the dopamine processing speed and effect, and is used to increase the pretreatment speed, which has the advantages of reducing costs and improving efficiency.

[0047] A pipeline is provided in the hydrogen enrichment area 519 to communicate with the hydrogen storage tank 530. Similarly, a valve switch is provided on the pipeline to control the flow of hydrogen.

[0048] Further, the desalination module of the present invention includes a power supply 540, which can be a direct current power supply. When desalting, it generates an electric field by supplying power, so that zinc chloride and a small amount of sodium chloride ions in the steel paper migrate out of the steel paper and enter the water in the steel paper treatment area. Specifically, cations such as zinc migrate out of the steel paper and enter the water in the steel paper treatment area under the action of the electric field, and enter the hydrogen enrichment area through the second cation exchange membrane. At the same time, anions such as chloride ions also migrate out of the steel paper under the action of the electric field, but they move toward the anode 511 and enter the salt enrichment area through the anion exchange membrane, at which time they form a high-salinity area with cations such as zinc coming from the oxygen enrichment area 516 through the first cation exchange membrane 513. On the other hand, water electrolysis also occurs in the oxygen enrichment area 516, so that oxygen anions produce oxygen at the anode. Similarly, a small amount of water electrolysis also occurs in the hydrogen enrichment area to produce hydrogen.

[0049] In the intermittent production system, the steel paper is placed in batches in the steel paper treatment area of ​​the desalination module for treatment. During the treatment, a voltage is applied between the anode and the cathode to generate a current of generally 0.01-2A, such as 0.02A, 0.03A, 0.04A, 0.05A, 0.06A, 0.07A, 0.08A, 0.09A, 0.1A, 0.2A, 0.3A, 0.4A, 0.5A, 0.6A, 0.7A, 0.8A, 0.9A, 1.0A, 1.2A, 1.4A, 1.6A, 1.8A, etc. The direct current generated by the present invention can be kept constant or arbitrarily changed within the above range. When the direct current is within the above range, it is advantageous to allow the ions in the steel paper, especially the zinc ions, to enter the water. Those skilled in the art can select within the above range according to the needs, such as the estimated zinc chloride concentration in the steel paper, the amount of steel paper put in at one time, etc. If the DC current is too large, the zinc chloride entering the water tends to electrolyze, which in turn affects the electrode life cycle and causes energy waste. On the other hand, if the DC current is too small, the ions in the steel paper may not migrate sufficiently.

[0050] In the production system of the present invention, during the current desalination, the treatment time of the steel paper is generally controlled to be 1 second to 5 minutes. The salt component can be advantageously migrated into the water within the above time range. Those skilled in the art can select a suitable time according to the estimated concentration of zinc chloride in the steel paper, such as 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds, 65 seconds, 70 seconds, 80 seconds, 90 seconds, 100 seconds, 110 seconds, 120 seconds, 2.5 minutes, 3 minutes, 4 minutes, 5 minutes, etc. If the treatment time is too long, the zinc chloride entering the water tends to be electrolyzed, thereby affecting the electrode life cycle and causing energy waste. On the other hand, if the treatment time is too short, the migration of zinc chloride may be insufficient.

[0051] In the present invention, in order to facilitate the migration of ions out of the steel paper during desalination, the direction of the DC power supply is preferably set so that the angle between the generated electric field direction and the steel paper surface is preferably 45 0 More than 50 0 Above, 60 0 Above, 70 0 Above, 80 0 The above is most preferably substantially vertical.

[0052] In an intermittent production system, the water in the desalting tank needs to be replaced regularly or after each steel paper treatment to ensure that the steel paper will not be contaminated by the water in the desalting tank.

[0053] In an exemplary continuous production system, the desalination tank of the present invention is configured to allow new water to flow continuously into the desalination tank, while the treated treated water continuously flows out of the desalination tank, and the water flowing out of different channels is collected separately. Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. Various adjustments or changes may be made to the exemplary embodiments of the present invention specification without departing from the scope or spirit of the present invention. The scope of the claims should be based on the broadest interpretation to cover all modifications and equivalent structures and functions.
