Description

By installing advanced sensors and automated control systems in the reactor, the reaction conditions can be monitored and dynamically adjusted in real time, thereby effectively ensuring the stability and repeatability of the preparation process and significantly improving the performance and product quality of the catalyst. This precise control capability is particularly important in the field of nanomaterial preparation, especially in the hydrothermal synthesis process, where nanomaterials not only need to precisely control their size and morphology, but also need to achieve uniform distribution of multiple metal components to meet the performance requirements of different applications. However, in the prior art, multiple reaction operations are usually required for the preparation of multi-component nanomaterials, which not only increases the frequency of disassembly and assembly of the reactor and the waiting time for heating and cooling, but also leads to high consumption of time, energy, and energy, restricting the efficiency and economy of industrial applications.

However, the synthesis of nanomaterials often involves a variety of metal salts or metal organic compounds as raw materials, and the reaction conditions (such as temperature, pressure, reaction time, etc.) between these raw materials may vary significantly, making it difficult to complete multiple reactions simultaneously in the same reactor.

DETAILED DESCRIPTION
[0024] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings:
[0025] like Figure 1 As shown, the utility model is a reactor liner for preparing nanomaterials by solvent thermal method or hydrothermal method, comprising a cylindrical liner body 1, a sealing cover 11 arranged on the top of the liner body 1, a partition is arranged inside the liner body 1, and the reactor liner is divided into two reactors by the partition, namely a first reactor 101 containing a reaction solution or reactant for preparing nanomaterials and a second reactor 102 containing another reaction solution or reactant for preparing nanomaterials; the partition is made of high temperature resistant and corrosion resistant material, and polytetrafluoroethylene is preferably used in this embodiment. The olefin material has good sealing performance and can ensure independent sealing between different reaction areas; a through hole 5 for installing a one-way floating air valve 6 is provided on the top of the partition, and the two ends of the one-way floating air valve 6 are respectively located in the first reactor 101 and the second reactor 102. The one-way floating air valve 6 is made of corrosion-resistant material and is designed with an anti-backflow device to avoid leakage or backflow of volatile substances. This embodiment preferably uses a thin film one-way floating pneumatic valve, which can achieve the transfer of volatile substances as long as there is a pressure difference generated by a chemical reaction.
[0026] With the aid of the aforementioned technical solution, the utility model divides the reactor lining into two reactors by a partition in the same reactor lining, and places two or more reactants or reaction solutions in the two reactors respectively to achieve the purpose of simultaneously carrying out the reactions in one reactor, thereby solving the problem in the prior art that it is difficult to complete multiple reactions simultaneously in the same reactor, and that the reactor needs to be frequently disassembled and assembled due to multiple reactions, and that the temperature needs to be raised or lowered.
[0027] like Figures 2 to 5 Furthermore, the lining body 1 also includes a plurality of positioning columns 2 arranged at the bottom of the lining body 1 and distributed in multiple rows along a diameter direction parallel to the lining body 1. In this embodiment, the number of positioning columns 2 in each row is two; the partition includes a main board 3 and a sub-board 4 that are slidably connected, and the bottom of the main board 3 and the bottom of the sub-board 4 are both provided with long strip holes 9 (such as Figure 5 As shown), by means of the cooperation of the aforementioned different rows of positioning columns 2 and the long holes 9, the partition can be located at different positions in the reactor liner, thereby changing the volume of the first reactor 101 and the second reactor 102 to adapt to different reaction requirements.
[0028] like Figure 3 As shown, the left side of the main board 3 is provided with a slot 301 with three openings (specifically, the top, the bottom, and the left side near the sub-board 4), and the inner wall of the slot 301 is symmetrically provided with two stoppers 302 extending in the vertical direction, and the material of the stoppers 302 is consistent with that of the partition (such as Figure 4As shown); the right side of the sub-board 4 is T-shaped, and the opening width of the slot 301 matches the T-shaped side of the sub-board 4. The stopper 302 and the T-shaped structure on the right side of the sub-board 4 can prevent the sub-board 4 from escaping from the slot 301 of the main board 3; a plurality of elastic members are arranged between the bottom of the slot 301 and the T-shaped side of the sub-board 4, and the elastic members are in a compressed state, so that the elastic force provided by the elastic members tends to cause the sub-board 4 to escaping from the slot 301 of the main board 3. In this embodiment, the elastic member is a spring 8; a plurality of correspondingly distributed grooves 10 are arranged on the bottom of the slot 301 and the T-shaped side of the sub-board 4. In this embodiment, three groups of six correspondingly arranged grooves 10 are provided, and the two ends of the spring 8 are respectively arranged In the corresponding groove 10, the purpose of such design is not only to prevent the spring 8 from shaking in the vertical direction, but also when the length of the partition changes, the spring 8 in the compressed state exerts elastic force, so that the main board 3 and the sub-board 4 are displaced in the direction of expansion, and the plug-in cooperation of the long hole 9 and the positioning column 2 arranged at the bottom limits the main board 3 and the sub-board 4 to be displaced only along the length direction after the sub-board 4 and the main board 3 are initially positioned; and because the elastic force of the spring 8 is toward the direction of expansion of the main board 3 and the sub-board 4 at this time, the sub-board 4 is away from the left side of the main board 3 and the main board 3 is away from the right side of the sub-board 4. After the first sealing gasket 701 is installed, they are tightly fitted with the inner wall of the reactor liner to ensure the sealing between the two reactors.
[0029] A first sealing gasket 701 is provided at the bottom of the main board 3, on the right side away from the sub-board 4, and at the bottom of the sub-board 4, on the left side away from the main board 3. The first sealing gasket 701 can prevent the reactant or reaction solution of one reactor from flowing into another reactor. The long hole 9 passes through the first sealing gasket 701. Preferably, the end of the first sealing gasket 701 provided on the bottom of the sub-board 4 is T-shaped, so as to match the first sealing gasket 701 on the bottom of the main board 3 to ensure sealing. At the same time, a second sealing gasket 702 (such as Figure 4 As shown in FIG. 1 ), when the sub-board 4 slides in the slot 301, the second sealing gasket 702 is used to prevent the reactant or reaction solution from entering the slot 301 and damaging the spring 8. Furthermore, the top of the main board 3 and the top of the sub-board 4 are also provided with a first sealing gasket 701, which is used to cooperate with the sealing cover 11 to achieve a better sealing effect.
[0030] The working principle of the reactor liner for preparing nanomaterials by solvent thermal method or hydrothermal method is as follows: first, a partition is inserted into the position of the positioning column 2 of the required reaction volume, and the reactor liner is divided into a first reactor 101 and a second reactor 102 of two required volumes, wherein the first reactor 101 is filled with a reaction solution or reactant for preparing nanomaterials, and the second reactor 102 is filled with another reaction solution or reactant for preparing nanomaterials, and then the sealing cover 11 is covered, and the entire reactor liner is placed in a stainless steel tank body and tightly sealed, and the entire reactor is heated at a set temperature, and when volatile substances are generated in one reactor, they can enter the other reactor through a single-way floating air valve 6, so that two reactants or reaction solutions are carried out simultaneously in one reactor, avoiding the disassembly and assembly of the reactor for two or even multiple reactions, and waiting for the temperature rise and fall process, which greatly saves time, energy and energy consumption.
[0031] As a first embodiment of the present invention, when the partition is located at Figure 7 In the position state shown, a partition is inserted into the positioning column 2 located on the diameter of the liner body 1 inside the reactor liner, and the reactor liner is divided into two independent areas of the same volume by the partition. The first reaction solution containing nickel-cobalt salt is placed in the first reactor 101, and the second reaction substance containing volatile sulfur source is placed in the second reactor 102. After the sealing cover 11 is covered, the volatile sulfur source produced in the second reactor 102 is introduced into the first reactor 101 containing nickel-cobalt salt through the one-way floating air valve 6 to participate in the precipitation reaction of nickel salt. During the whole reaction process, the temperature of the reactor is controlled at 180°C, the pressure is controlled at 4 MPa, and the reaction time is 10 hours; the experimental results show that the obtained product is a uniformly distributed nickel-cobalt bimetallic sulfide nanomaterial with uniform particle size distribution.
[0032] As a second embodiment of the present utility model, Figure 7 Based on the position state shown in FIG. 1 , the sub-board 4 of the partition is retracted into the slot 301 and inserted into the positioning posts 2 of other rows as needed, so that the partition is located as shown in FIG. Figure 8 The position state shown, at this time, the volume of the two reactors is no longer the same (at this time, the volume of the first reactor 101 is greater than the volume of the second reactor 102), and the first reaction solution containing nickel cobalt salt is placed in the first reactor 101, and the second reaction material containing volatile sulfur source is placed in the second reactor 102. After the sealing cover 11 is covered, the volatile sulfur source produced in the second reactor 102 is introduced into the first reactor 101 containing nickel cobalt salt through the one-way floating air valve 6 to participate in the precipitation reaction of nickel salt. During the entire reaction process, the temperature of the reactor is controlled at 150°C, the pressure is controlled at 2 MPa, and the reaction time is 12 hours; the experimental results show that the obtained product is a uniformly distributed nickel cobalt bimetallic sulfide nanomaterial with a uniform particle size distribution.
[0033] In another embodiment of the utility model, a plurality of partitions can be arranged in the lining body 1 to divide the reactor lining into a plurality of reactors, and different metal organic compounds (such as titanate, zirconate, etc.) are placed in the plurality of reactors respectively. The transfer of volatile organic matter is achieved through a single-way floating air valve 6, so that the utility model can carry out more than two reactions simultaneously in the same reactor, and can also obtain a nano-composite oxide material with multiple metal components.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not deviate from the design and scope of the technical solution of the utility model.
