Description

Technical Field

[0001] The present invention relates to the technical field of reactors, in particular to a conversion reactor for preparing green methanol from biomass raw materials. Background Art

[0002] In the process of producing green methanol from biomass feedstock, the shift reactor adjusts the synthesis gas ratio through the water-gas shift reaction. The core of this process is the efficient contact between the catalyst and the feed gas. Existing shift reactors mostly use a fixed-bed structure, with the catalyst statically deposited within the reactor. This presents the following problems: First, the reaction path is fixed and short, limiting the contact time between the feed gas and the catalyst, which can lead to low conversion rates due to insufficient mass transfer. Second, long-term static accumulation of the catalyst can cause local compaction, reducing the effective contact area. Furthermore, reaction byproducts (such as carbon powder and salts) can easily remain on the reactor walls, affecting heat transfer and gas circulation. Third, the reaction path length cannot be adjusted according to the feed gas composition, which can easily lead to path waste for low-concentration feed gas. Furthermore, once the catalyst is fixed in place, the underutilized portion is difficult to reactivate, resulting in high catalyst loss and increased production costs.

[0003] In response to the above problems, this invention document proposes a conversion reactor for producing green methanol from biomass raw materials. Summary of the Invention

At the same time, the reaction by-products are easily left on the inner wall of the reactor, affecting heat transfer and gas circulation; and the reaction path length cannot be adjusted according to the composition of the raw gas, resulting in a high catalyst loss rate and increased production costs. The proposed conversion reactor for preparing green methanol from biomass raw materials is

[0015] Compared with the prior art, the present invention provides a shift reactor for preparing green methanol from biomass raw materials, which has the following beneficial effects: 1. The conversion reactor for preparing green methanol from biomass raw materials can store the catalyst through the elastic spiral diaphragm structure, so that the catalyst is arranged in a spiral shape in the conversion reaction chamber container, effectively extending the reaction path of the raw gas and providing more sufficient contact time for the water-gas shift reaction. The pressurizing component reciprocates and pressurizes the elastic spiral diaphragm structure, so that the elastic spiral diaphragm structure elastically restores its shape and stretches and contracts, which can clean the inner wall of the conversion reaction chamber container. The elastic spiral diaphragm structure stretches and contracts, which can drive the internal catalyst to shake or displace, breaking the static stacking state, significantly increasing the contact area between the raw gas and the active sites of the catalyst, improving the mass transfer efficiency, and providing higher-quality raw gas for subsequent methanol synthesis.

[0016] 2. The conversion reactor for preparing green methanol from biomass raw materials drives the support plate to retract through the cylinder telescopic structure, so that the sealing plate is separated from the airflow changing port. At the same time, the support plate drives the guide slide to move, and the guide slide drives the longitudinal guide rail to move through the connecting piece. The longitudinal guide rail drives the sealing grid layer to move through the longitudinal guide rail, so that the mesh holes of the sealing grid layer and the mesh holes of the movable inner combined network structure are staggered to maintain the seal. At this time, the raw gas can be directly discharged upward through the airflow changing port and the conversion path conveying cylinder structure. This method can select the path length according to the material to be processed, avoiding the problem of resource waste caused by a long path, thereby improving the operation flexibility of the equipment.

[0017] 3. The conversion reactor for preparing green methanol from biomass raw materials opens the airflow change port through the airflow path conversion component, and the airflow path conversion component drives the internal combination network sealing component to close the movable internal combination network structure, so that the raw gas is discharged directly through the airflow change port, avoiding entering the upper catalyst to cause resource waste. Moreover, since the upper raw gas is not fully active due to the post-contact reaction, the catalyst is directly discharged by opening the lower catalyst discharge port, and the upper catalyst discharge port is opened to receive the upper catalyst. This method can conveniently transfer the catalyst that is not fully consumed in the seldom used upper path to the lower path, so that the catalyst can be reused in the area with higher reaction intensity, give full play to its activity potential, reduce resource waste caused by premature abandonment of the catalyst, and facilitate catalyst separation, effectively reduce the frequency of catalyst procurement and replacement, and reduce costs.

The net frames are staggered so that they can slide between each other, thereby allowing the elastic spiral spacer structure 202 to smoothly expand and contract, and the movable inner combined net structure 205 can intercept the catalyst and keep the catalyst stored in sections. At the same time, the movable inner combined net structure 205 has mesh holes to ensure the spiral flow of the raw gas. Four catalyst discharge ports 101 are provided on one side of the conversion reaction chamber container 100. By opening the corresponding catalyst discharge ports 101, the catalyst that needs to be replaced can be taken out, which is convenient for segmented replacement of the catalyst. An airflow change port 208 is provided on the conversion path conveying cylinder structure 201. The airflow change port 208 can ensure that the raw gas is directly discharged, thereby changing the discharge path and facilitating the rapid discharge of the raw gas. The inner combined net sealing component 206 includes a sealing grid layer 2061, which is set on the net frame. The sealing grid layer 2061 corresponds to the net frame to ensure the smooth flow of raw gas. After the sealing grid layer 2061 is translated, the mesh holes of the sealing grid layer 2061 are staggered with the mesh holes of the movable inner combined net structure 205, so as to seal the movable inner combined net structure 205, so that the raw gas can smoothly change the discharge path through the airflow changing port 208, and two transverse guide rails 2067 are fixedly connected to the net frame. The transverse guide rails 2067 can guide the sealing grid layer 2061, so that the sealing grid layer 2061 can slide smoothly on the transverse guide rails 2067 through the transverse guide grooves 2068.

A cylinder telescopic structure 2072 is fixedly installed on the cylinder fixing seat 2071. The cylinder telescopic structure 2072 can be fixed by the cylinder fixing seat 2071 to keep the cylinder telescopic structure 2072 stable. The cylinder telescopic structure 2072 drives the support plate 2073 to move, so that the support plate 2073 drives the sealing plate 2074 to separate from the airflow change port 208. , thereby keeping the airflow changing port 208 open. When the cylinder telescopic structure 2072 is extended, the sealing plate 2074 can be smoothly embedded in the airflow changing port 208, thereby maintaining the sealing of the path-changing conveying cylinder structure 201.

[0025] In this embodiment: the support plate 2073 is driven to retract by the cylinder telescopic structure 2072, so that the sealing plate 2074 is separated from the airflow changing port 208, and at the same time the support plate 2073 drives the guide slide 2065 to move, and the guide slide 2065 drives the longitudinal guide rail 2063 to move through the connecting piece 2064, and the longitudinal guide rail 2063 drives the sealing grid layer 2061 to move through the longitudinal guide rail 2062, so that the mesh of the sealing grid layer 2061 is staggered with the mesh of the movable inner combined net structure 205 to maintain the seal. At this time, the raw gas can be discharged directly upward through the airflow changing port 208 and the path conversion conveying cylinder structure 201.

[0026] Example 3: Reference Figure 2-Figure 3 and Figure 5-Figure 7 The conversion reactor for preparing green methanol from biomass raw materials includes an adjustable reaction mechanism 200, which includes a conversion path conveying cylinder structure 201. The conversion path conveying cylinder structure 201 is fixedly connected to the conversion reaction chamber container 100. An elastic spiral diaphragm structure 202 is provided on the outside of the conversion path conveying cylinder structure 201.

An airflow path conversion component 207 is provided inside the path conversion conveying cylinder structure 201. The part of the airflow path conversion component 207 extending out of the path conversion conveying cylinder structure 201 is connected to two internal combined net sealing components 206. The two internal combined net sealing components 206 are respectively arranged on both sides of the movable internal combined net structure 205, and the movable internal combined net structure 205 is fixedly connected to the elastic spiral spacer structure 202.

[0027] In this embodiment: the airflow change port 208 is opened by the airflow path conversion component 207, and the airflow path conversion component 207 drives the inner combination network sealing component 206 to close the movable inner combination network structure 205, so that the raw gas is discharged directly through the airflow change port 208, avoiding entering the upper part of the catalyst to cause resource waste, and because the upper part of the raw gas is not fully active due to the post-contact reaction, the catalyst is directly discharged by opening the lower catalyst discharge port 101, and the upper catalyst discharge port 101 is opened to receive the upper catalyst. This method can conveniently replace the catalyst that is not fully consumed in the upper part of the path that is not frequently used to the lower part of the path, so that the catalyst can be reused in the area with higher reaction intensity, give full play to its activity potential, reduce the waste of resources caused by premature abandonment of the catalyst, and facilitate catalyst separation, effectively reduce the frequency of catalyst procurement and replacement, and reduce costs.

[0028] Working principle: When preparing biomass raw materials, water gas is introduced through the lower inlet of the shift reaction chamber container 100, so that the water gas contacts the catalyst to undergo a shift reaction, and moves upward along the spiral shape of the elastic spiral spacer structure 202 to fully contact the catalyst for reaction; During the water-gas shift reaction between the catalyst and the catalyst, the cylinder telescopic device 2032 extends, which drives the annular ring 2033 to move. The annular ring 2033 drives the annular net 2034 to move. The annular net 2034 applies pressure to the elastic spiral diaphragm structure 202, causing the elastic spiral diaphragm structure 202 to deform. When the cylinder telescopic device 2032 retracts, the annular net 2034 moves away from the elastic spiral diaphragm structure 202, causing the elastic spiral diaphragm structure 202 to recover its deformation and move the catalyst, thereby improving mass transfer efficiency. The processed raw gas is discharged upward through the annular net 2034 and discharged through the catalyst discharge port 101 above the shift reaction chamber container 100. When it is necessary to switch the discharge path, the cylinder telescopic structure 2072 retracts, so that the cylinder telescopic structure 2072 drives the support plate 2073 to move, and the support plate 2073 drives the sealing plate 2074 to disengage from the airflow changing port 208, and the support plate 2073 drives the guide slide 2065 to move, and the guide slide 2065 drives the connecting piece 2064 to move, and the connecting piece 2064 drives the sealing grid layer 2061 to move through the longitudinal guide rail 2063 and the longitudinal guide rail 2062, so that the mesh of the sealing grid layer 2061 is staggered with the mesh of the movable inner combined network structure 205, so as to maintain the sealing of the movable inner combined network structure 205. At this time, the raw gas can enter the airflow changing port 208 after passing through the catalyst in the lower part, and be discharged upward through the path changing conveying cylinder structure 201.
