Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an apparatus for preparing ferric nitrate. Background Technology

[0002] Ferric nitrate is an important chemical raw material with wide applications in the dye industry, pharmaceutical field, and chemical industry. Traditional methods for preparing ferric nitrate mainly involve reaction kettles.

[0003] Currently, ferric nitrate is mainly produced through a chemical reaction, which requires specific temperature and pressure conditions. Existing methods use reactors for preparation, which are typically open. This makes it difficult to control the temperature and pressure within the reactor, resulting in low efficiency in ferric nitrate production. Furthermore, the nitrogen oxides generated during the reaction cannot be effectively collected, leading to environmental pollution. Utility Model Content

[0004] In view of this, the present invention provides a ferric nitrate preparation apparatus to solve the problems of low ferric nitrate generation efficiency and ineffective collection of nitrogen oxides generated during the reaction process when ferric nitrate is prepared by using a reaction vessel.

The reaction component has a reaction chamber, which is intermittently connected to a storage chamber to receive a first reactant. The circulation component has a circulation channel, the two ends of which are respectively connected to the two ends of the reaction component and are connected to the reaction chamber and a second reactant. A collection structure having a collection channel, the two ends of which are respectively connected to the reaction chamber and a gas collection device to collect the reaction gas in the reaction chamber; The reaction assembly includes a reaction shell and several heat exchange components. The reaction shell has a reaction chamber. All the heat exchange components are disposed on the inner wall of the reaction chamber, and all the heat exchange components are arranged in layers and spaced apart on the inner wall of the reaction chamber.

[0006] Beneficial effects: By connecting the conveying structure, reaction structure, and collection structure, the first reactant stored in the storage chamber can fall into the reaction chamber, and the second reactant can flow into the reaction chamber through the circulation component. This allows the first and second reactants to react within the reaction chamber. Simultaneously, the collection structure can transport the gas generated by the reaction to a gas collection device through a collection channel, preventing the gas generated by the reaction from increasing the gas pressure in the reaction chamber or flowing into the outside air and polluting it after the reaction. All heat exchange components can exchange heat within the reaction chamber to control the temperature and ensure that the temperature within the reaction chamber is at the optimal temperature for the first and second reactants to react, thereby improving the reaction efficiency of the first and second reactants.

[0007] In one optional embodiment, the reaction assembly further includes a plurality of screening elements, all of which are spaced apart within the reaction chamber. Each screening element has a plurality of screening sections for screening the first reaction element. The size of the screening sections on the screening elements gradually decreases from one end to the other in the direction from one end of the reaction housing.

[0008] Beneficial effects: By setting the reaction assembly, several screening elements are also included. In this embodiment, the screening elements are screening plates. All the screening elements are spaced apart in the reaction chamber, and each screening element has several screening sections. In this embodiment, the screening sections are screening holes. When the first reactant falls into the reaction chamber, the screening sections can screen the first reactant so that the first reactants of different sizes can react separately, thereby improving the reaction efficiency of the first reactant and the second reactant. In addition, in the direction from one end to the other of the reaction shell, the size of the screening sections on all the screening elements gradually decreases so as to gradually screen the first reactant, so that the smallest first reactant can contact the second reactant first.

[0009] In one optional embodiment, the circulation assembly includes a circulation component, a first connecting component, and a second connecting component. The circulation component is disposed on one side of the reaction shell, and both ends of the first connecting component and the second connecting component are connected to the circulation component and the reaction shell.

In this way, the second reaction component can be recycled through the circulation channel.

[0011] In one optional embodiment, the circulation assembly further includes a third connecting member and a fourth connecting member, one end of the third connecting member being connected to the first connecting member and the other end being connected to the second reaction member, and one end of the fourth connecting member being connected to the second connecting member and the other end being connected to the ferric nitrate collecting device; the first connecting member, the second connecting member, the third connecting member, and the fourth connecting member together form the circulation channel.

[0012] Beneficial effects: By setting the circulation component, a third connecting member and a fourth connecting member are included. In this embodiment, the third connecting member and the fourth connecting member are respectively a third connecting pipe and a fourth connecting pipe. One end of the third connecting member is connected to the first connecting member, and the other end is connected to the second reactant, so that the second reactant can flow into the circulation channel through the third connecting member and into the reaction chamber within the circulation channel. One end of the fourth connecting member is connected to the second connecting member, and the other end is connected to the ferric nitrate collection device. Thus, when the second reactant and the first reactant react in the reaction chamber to generate ferric nitrate, the ferric nitrate can enter the circulation channel with the second reactant and enter the ferric nitrate collection device through the fourth connecting member. Specifically, the first connecting member, the second connecting member, the third connecting member, and the fourth connecting member together form a circulation channel, thereby allowing the second reactant and ferric nitrate to flow within the circulation channel.

[0013] In one optional embodiment, the collection structure includes a collection pipe and a first regulating member, one end of the collection pipe being connected to the reaction chamber and the other end being connected to the gas collection device, and the first regulating member being disposed on the collection pipe.

In this way, the gas generated in the reaction chamber can flow into the gas collection device through the collection pipe. The first regulating component is set on the collection pipe, so the opening and closing of the collection channel can be controlled by the first regulating component, and the gas pressure in the reaction chamber can be controlled by the first regulating component to ensure that the gas pressure in the reaction chamber is at the optimal gas pressure state when the first and second reactants react, which is beneficial to improving the reaction efficiency.

[0015] In one optional embodiment, the collection structure further includes an adjustment pipe and a second adjustment element, one end of the adjustment pipe being connected to the storage cavity and the other end being connected to the gas collection device, and the second adjustment element being disposed on the collection pipe.

[0016] Beneficial effects: The collection structure also includes a regulating pipe and a second regulating component. In this embodiment, the second regulating component is a second regulating valve. One end of the regulating pipe is connected to the storage chamber, and the other end is connected to the gas collection device, so that the air in the storage chamber can be regulated through the regulating pipe, thereby controlling the gas pressure in the storage chamber. The second regulating component is set on the regulating pipe to control the opening and closing of the regulating pipe. In this way, the gas pressure in the storage chamber can be regulated to be greater than the gas pressure in the reaction chamber, so as to ensure that the gas in the reaction chamber will flow into the storage chamber.

[0017] In one optional embodiment, the collection structure further includes a first sensor and a second sensor, the first sensor being disposed on the collection pipe and the second sensor being disposed on the regulating pipe, the first sensor and the second sensor being used to sense the gas pressure in the storage chamber and the reaction chamber, respectively.

[0020] Beneficial effects: By setting the material conveying structure including a material conveying component and a storage component, in this embodiment the material conveying component and the storage component are respectively a material conveying chamber and a storage chamber. The material conveying component has a material conveying cavity with one end open, and the first reactant is conveyed into the material conveying cavity through the opening. The storage component has a storage cavity, and the storage cavity and the material conveying cavity are connected, so that the first reactant in the material conveying cavity can fall into the storage cavity, and then fall into the reaction cavity in the storage cavity to react with the second reactant.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0030] According to embodiments of this utility model, in one aspect, an apparatus for preparing ferric nitrate is provided, such as... Figures 1 to 4 As shown, the device includes a conveying structure 1, a reaction structure, and a collecting structure 3. The conveying structure 1 has a storage cavity suitable for storing the first reactant 4. The reaction structure includes a reaction assembly and a circulation assembly 22. The reaction assembly has a reaction cavity, which is intermittently connected to the storage cavity to receive the first reactant 4. The circulation assembly 22 has a circulation channel, the two ends of which are respectively connected to the two ends of the reaction assembly and are connected to the reaction cavity and the second reactant 5. The collecting structure 3 has a collecting channel, the two ends of which are respectively connected to the reaction cavity and a gas collecting device to collect the reaction gas in the reaction cavity. The reaction assembly includes a reaction shell 211 and several heat exchangers 212. The reaction shell 211 has a reaction cavity, and all the heat exchangers 212 are disposed on the inner wall of the reaction cavity, and all the heat exchangers 212 are layered and spaced apart on the inner wall of the reaction cavity.

[0031] The ferric nitrate preparation apparatus described above comprises a conveying structure 1, a reaction structure, and a collecting structure 3 connected in series. The conveying structure 1 has a storage cavity that can store a first reactant 4. The reaction structure includes a reaction component and a circulation component 22. The reaction component has a reaction chamber that is intermittently connected to the storage cavity, allowing the first reactant 4 stored in the storage cavity to fall into the reaction chamber for reaction. The circulation component 22 has a circulation channel with its two ends connected to the opposite ends of the reaction component. The circulation channel is connected to the reaction chamber through its two ends connected to the reaction component. The circulation channel is also connected to a second reactant 5, allowing the second reactant 5 to enter the reaction chamber through the circulation channel, thereby enabling the first reactant 4 and the second reactant 5 to react within the reaction chamber.

[0032] Meanwhile, since the two ends of the circulation channel are connected and communicated with the two opposite ends of the reaction chamber, when the second reactant 5 flows into the reaction chamber through the circulation channel to react with the first reactant 4, some of the second reactant 5 will not participate in the reaction. When the reaction chamber is filled, the second reactant 5 will flow back into the reaction chamber through the circulation channel to react with the first reactant 4. In this way, the utilization efficiency of the second reactant 5 can be improved and the waste of the second reactant 5 can be avoided.

[0033] Furthermore, when the first reactant 4 and the second reactant 5 react in the reaction chamber, the first reactant 4 and the second reactant 5 generate gas in the reaction chamber. This gas is polluting and increases the gas pressure in the reaction chamber. Therefore, the collection structure 3 is configured to have a collection channel, and the two ends of the collection channel are connected to the reaction chamber and the gas collection device, respectively. This allows the gas generated in the reaction chamber to flow into the gas collection device through the collection channel, thereby avoiding the situation where the gas accumulates in the reaction chamber, causing changes in the gas pressure in the reaction chamber and affecting the reaction efficiency of the first reactant 4 and the second reactant 5. It also prevents the gas from flowing into the outside air after the reaction is completed and polluting the outside air.

[0034] Specifically, when the first reactant 4 and the second reactant 5 react in the reaction chamber, the first reactant 4 and the second reactant 5 generate a large amount of heat in the reaction chamber. Therefore, the reaction assembly is configured to include a reaction shell 211 and a plurality of heat exchangers 212. In this embodiment, the heat exchangers 212 are heat exchangers. The reaction shell 211 has a reaction chamber, and all the heat exchangers 212 are disposed on the inner wall of the reaction chamber. Thus, the temperature in the reaction chamber can be controlled by all the heat exchangers 212, thereby making the temperature in the reaction chamber the optimal temperature when the first reactant 4 and the second reactant 5 react, avoiding the heat generated by the reaction from affecting the reaction efficiency, and improving the reaction efficiency of the first reactant 4 and the second reactant 5 in the reaction chamber.

[0035] In addition, all heat exchangers 212 are arranged in layers and spaced apart on the inner wall of the reaction chamber. This improves the heat exchange uniformity of all heat exchangers 212 in the reaction chamber, ensuring that the temperature of the entire reaction chamber is in a balanced state. This ensures that the first reactant 4 and the second reactant 5 are at the optimal reaction temperature throughout the reaction chamber, thereby further improving the reaction efficiency of the first reactant 4 and the second reactant 5.

[0036] In summary, by connecting the conveying structure 1, the reaction structure, and the collecting structure 3, the first reactant 4 stored in the storage chamber can fall into the reaction chamber, and the second reactant 5 can flow into the reaction chamber through the circulation component 22. This allows the first reactant 4 and the second reactant 5 to react within the reaction chamber. Simultaneously, the collecting structure 3 can transport the gas generated by the reaction to the gas collecting device through the collecting channel to prevent the gas generated by the reaction from increasing the gas pressure in the reaction chamber or flowing into the outside air and polluting the outside air after the reaction. All the heat exchange components 212 can exchange heat in the reaction chamber to control the temperature in the reaction chamber and ensure that the temperature in the reaction chamber is at the optimal temperature for the first reactant 4 and the second reactant 5 to react, thereby improving the reaction efficiency of the first reactant 4 and the second reactant 5.

[0037] In one embodiment, such as Figure 1 As shown, the reaction assembly also includes several screening elements 213. All screening elements 213 are spaced apart in the reaction chamber. Each screening element 213 has several screening sections, which are used to screen the first reaction element 4. In the direction from one end to the other end of the reaction shell 211, the size of the screening sections on the screening elements 213 gradually decreases.

[0038] The ferric nitrate preparation apparatus described above further includes several screening elements 213 by setting up a reaction assembly. In this embodiment, the screening elements 213 are screening plates. All the screening elements 213 are spaced apart in the reaction chamber, and each screening element 213 has several screening sections. In this embodiment, the screening sections are screening holes. When the first reactant 4 falls into the reaction chamber, the screening sections can screen the first reactant 4 so that the first reactants 4 of different sizes can react separately, thereby improving the reaction efficiency of the first reactant 4 and the second reactant 5. In addition, in the direction from one end to the other end of the reaction shell 211, the size of the screening sections on all the screening elements 213 gradually decreases, so as to gradually screen the first reactant 4, so that the first reactant 4 with the smallest size can preferentially contact the second reactant 5.

[0039] Specifically, when the first reactant 4 and the second reactant 5 are reacting, the contact area between the first reactant 4 and the second reactant 5 is an important factor affecting the reaction efficiency of the first reactant 4 and the second reactant 5. Therefore, the smaller the size of the first reactant 4, the larger the contact area between the first reactant 4 and the second reactant 5 of the same mass. Thus, the smaller the size of the first reactant 4 and the second reactant 5, the higher the reaction efficiency.

[0040] In one embodiment, such as Figures 1 to 3 As shown, the circulation component 22 includes a circulation element 221, a first connecting element 222, and a second connecting element 223. The circulation element 221 is disposed on one side of the reaction shell 211. Both ends of the first connecting element 222 and the second connecting element 223 are connected to the circulation element 221 and the reaction shell 211. The first connecting element 222 and the second connecting element 223 together form a circulation channel.

[0041] The ferric nitrate preparation apparatus with the above-described structure includes a circulation component 22 comprising a circulation element 221, a first connecting element 222, and a second connecting element 223. In this embodiment, the circulation element 221, the first connecting element 222, and the second connecting element 223 are respectively a circulation pump, a first connecting pipe, and a second connecting pipe. The circulation element 221 is disposed on one side of the reaction shell 211. Both ends of the first connecting element 222 and the second connecting element 223 are respectively connected to the circulation element 221 and the reaction shell 211, and the first connecting element 222 and the second connecting element 223 together form a circulation channel, thereby allowing the second reaction element 5 to be recycled through the circulation channel.

[0042] In one embodiment, such as Figures 1 to 3As shown, the circulation component 22 also includes a third connecting member 224 and a fourth connecting member 225. One end of the third connecting member 224 is connected to the first connecting member 222 and the other end is connected to the second reaction member 5. One end of the fourth connecting member 225 is connected to the second connecting member 223 and the other end is connected to the ferric nitrate collecting device. The first connecting member 222, the second connecting member 223, the third connecting member 224 and the fourth connecting member 225 together form a circulation channel.

[0043] The ferric nitrate preparation apparatus described above further includes a third connecting member 224 and a fourth connecting member 225 by setting a circulation component 22. In this embodiment, the third connecting member 224 and the fourth connecting member 225 are respectively a third connecting pipe and a fourth connecting pipe. One end of the third connecting member 224 is connected to the first connecting member 222, and the other end is connected to the second reactant 5, so that the second reactant 5 can flow into the circulation channel through the third connecting member 224 and into the reaction chamber within the circulation channel. One end of the fourth connecting member 225 is connected to the second connecting member 223, and the other end is connected to the ferric nitrate collection device, so that when the second reactant 5 and the first reactant 4 react to generate ferric nitrate in the reaction chamber, the ferric nitrate can enter the circulation channel with the second reactant 5 and enter the ferric nitrate collection device through the fourth connecting member 225. Specifically, the first connecting member 222, the second connecting member 223, the third connecting member 224, and the fourth connecting member 225 together form a circulation channel, thus allowing the second reactant 5 and ferric nitrate to flow within the circulation channel.

[0044] In one embodiment, such as Figure 1 As shown, the collection structure 3 includes a collection pipe 31 and a first adjusting member 32. One end of the collection pipe 31 is connected to the reaction chamber, and the other end is connected to the gas collection device. The first adjusting member 32 is disposed on the collection pipe 31.

[0045] The ferric nitrate preparation apparatus described above includes a collection structure 3 comprising a collection pipe 31 and a first regulating element 32. In this embodiment, the first regulating element 32 is a first regulating valve. The collection pipe 31 is configured to have a collection channel, with one end connected to the reaction chamber and the other end connected to a gas collection device. This allows the gas generated in the reaction chamber to flow into the gas collection device through the collection pipe 31. The first regulating element 32 is installed on the collection pipe 31, thereby controlling the opening and closing of the collection channel and controlling the gas pressure in the reaction chamber to ensure that the gas pressure in the reaction chamber is at the optimal pressure state during the reaction of the first reactant 4 and the second reactant 5, which is beneficial to improving the reaction efficiency.

[0046] In one embodiment, such as Figure 1As shown, the collection structure 3 also includes an adjustment pipe 33 and a second adjustment element 34. One end of the adjustment pipe 33 is connected to the storage chamber and the other end is connected to the gas collection device. The second adjustment element 34 is disposed on the collection pipe 31.

[0047] The ferric nitrate preparation apparatus described above further includes a regulating pipe 33 and a second regulating element 34 by setting the collection structure 3. In this embodiment, the second regulating element 34 is a second regulating valve. One end of the regulating pipe 33 is connected to the storage chamber, and the other end is connected to the gas collection device, so that the air in the storage chamber can be regulated by the regulating pipe 33, thereby controlling the gas pressure in the storage chamber. The second regulating element 34 is set on the regulating pipe 33 to control the opening and closing of the regulating pipe 33. In this way, the gas pressure in the storage chamber can be adjusted to be greater than the gas pressure in the reaction chamber, so as to ensure that the gas in the reaction chamber flows into the storage chamber.

[0048] In one embodiment, such as Figure 1 As shown, the collection structure 3 also includes a first sensing element 35 and a second sensing element 36. The first sensing element 35 is disposed on the collection pipe 31, and the second sensing element 36 is disposed on the regulating pipe 33. The first sensing element 35 and the second sensing element 36 are used to sense the gas pressure in the storage chamber and the reaction chamber, respectively.

[0049] The ferric nitrate preparation apparatus with the above-described structure further includes a first sensing element 35 and a second sensing element 36 by setting the collection structure 3. In this embodiment, the first sensing element 35 and the second sensing element 36 are respectively a first gas pressure sensor and a second gas pressure sensor. The first sensing element 35 is set on the collection pipe 31, so as to sense the gas pressure in the reaction chamber and thus determine whether the first regulating element 32 needs to be turned on or off. The second sensing element 36 is set on the regulating pipe 33, so as to sense the gas pressure in the storage chamber and thus determine whether the second regulating element 34 needs to be turned on or off.

[0050] In one embodiment, such as Figure 1 and Figure 4 As shown, the material conveying structure 1 includes a material conveying component 11 and a storage component 12. The material conveying component 11 has a material conveying cavity with one end open. The first reaction component 4 is adapted to be conveyed into the material conveying cavity through the opening. The storage component 12 has a storage cavity, which is connected to the material conveying cavity to receive the first reaction component 4.

[0051] The ferric nitrate preparation apparatus described above includes a conveying structure 1 comprising a conveying component 11 and a storage component 12. In this embodiment, the conveying component 11 and the storage component 12 are a conveying chamber and a storage chamber, respectively. The conveying component 11 has a conveying cavity with one end open, through which the first reactant 4 is conveyed to the conveying cavity. The storage component 12 has a storage cavity, and the storage cavity and the conveying cavity are connected, so that the first reactant 4 in the conveying cavity can fall into the storage cavity and then into the reaction cavity to react with the second reactant 5.

[0052] In one embodiment, such as Figure 1 and Figure 4 As shown, the material conveying structure 1 also includes a conveying assembly 13, which includes a driving member 131 and a conveying member 132. One end of the conveying member 132 is connected to the material conveying chamber and the other end is connected to the storage chamber. The driving member 131 is disposed on the conveying member 132 to drive the conveying member 132 to convey the first reaction member 4 from the material conveying chamber to the storage chamber.

[0053] The ferric nitrate preparation apparatus with the above-described structure further includes a conveying component 13 by setting the conveying structure 1. The conveying component 13 specifically includes a driving component 131 and a conveying component 132. In this embodiment, the driving component 131 and the conveying component 132 are a driving motor and a screw conveying device, respectively. One end of the conveying component 132 is connected to the conveying chamber, and the other end is connected to the storage chamber. The driving component 131 is disposed on the conveying component 132. In this way, the driving component 131 can drive the conveying component 132 to convey the first reaction component 4 from the conveying chamber to the storage chamber, and the conveying component 132 can prevent the first reaction component 4 from leaking.

[0054] In one embodiment, such as Figures 1 to 4 As shown, the gas pressure in the storage chamber is greater than the gas pressure in the reaction chamber; the first reaction element 4 is iron powder or iron particles, and the second reaction element 5 is a mixed solution of nitric acid and hydrogen peroxide.

[0055] The ferric nitrate preparation apparatus described above, by setting the gas pressure in the storage chamber to be greater than the gas pressure in the reaction chamber, ensures that the gas generated by the reaction in the reaction chamber will not flow into the storage chamber, but can only flow into the gas collection device through the collection channel. It should be noted that the gas in the storage chamber is an inert gas, which is periodically injected into the storage chamber to ensure that the gas pressure in the storage chamber is always greater than the gas pressure in the reaction chamber, and to maintain positive pressure in the apparatus. By setting the first reactant 4 and the second reactant 5 as iron powder and a mixed solution of nitric acid and hydrogen peroxide, respectively, the first reactant 4 and the second reactant 5 can react in the reaction chamber to generate ferric nitrate. The first reactant 4 is made of iron powder, mainly because the small size of the iron powder can improve the reaction efficiency when the iron powder comes into contact with and reacts with the mixed solution of nitric acid and hydrogen peroxide.

[0056] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
