Description
Technical Field
[0001] The utility model belongs to the technical field of ethanol preparation, and particularly relates to an impurity separator for syngas in ethanol preparation. Background Technique
[0002] In the process of ethanol preparation, the quality of syngas plays a crucial role in the quality of the final ethanol product. However, at present in the field of ethanol preparation, syngas often contains various impurities, and these impurities will have an adverse impact on the subsequent ethanol production process.
[0003] There are many problems with traditional syngas impurity treatment methods. On the one hand, there is a lack of effective preliminary filtration means for large particle impurities in syngas, resulting in some large particle impurities entering the subsequent treatment link, increasing the workload of the subsequent separation components and reducing the processing efficiency of the entire system. On the other hand, the existing separation technologies are relatively single, such as cyclone separators, which are difficult to comprehensively and efficiently separate various impurities in syngas, thus affecting the purity of syngas and further affecting the quality of ethanol. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: an impurity separator for syngas in ethanol preparation, including a housing, an air inlet assembly, a separation assembly, an air outlet pipe, and a bracket.
[0005] The top of the air inlet assembly is fixedly connected to the bottom of the housing, and the air inlet assembly is used for rough filtering of syngas.
[0006] The separation assembly is installed in the inner cavity of the housing and is used for filtering impurities in syngas. The separation assembly includes an air inlet pipe and a guiding pipe. The bottom of the air inlet pipe is fixedly connected to the bottom of the inner cavity of the housing, the top of the air inlet pipe is fixedly connected to the bottom of the guiding pipe, the top of the guiding pipe is fixedly connected to the top of the inner cavity of the housing, a molecular sieve is fixedly connected to the inner side of the guiding pipe, a sieve cylinder is slidably connected to the inner side of the air inlet pipe, a top cover is slidably connected to the top of the sieve cylinder, and activated carbon particles are arranged inside the sieve cylinder. During use, the preliminarily filtered syngas enters the inside of the separation assembly upward, and after being filtered by the activated carbon in the separation assembly, it then moves to the molecular sieve through the guiding pipe. The molecular sieve adsorbs and separates specific impurities in the syngas. By setting the separation assembly to separate the impurities in the syngas, the molecular sieve and the activated carbon are used in combination. The activated carbon can adsorb some larger molecules and non-polar impurities, while the molecular sieve can adsorb some small molecule impurities and specific polar impurities, so as to achieve a more comprehensive filtering effect. The top cover of the sieve cylinder can be opened. When the adsorption effect of the activated carbon is poor, the top cover can be opened to replace the activated carbon, which is convenient for replacing the adsorbent in the sieve cylinder.
[0007] The bottom of the outlet pipe is fixedly connected to the top of the outer shell;
[0008] The bracket includes a fixing plate and support columns. Four corners of the bottom surface of the fixing plate are respectively fixedly connected with a support column. An outer shell mounting hole is provided on the fixing plate, and the inner wall of the outer shell mounting hole is fixedly connected to the outer wall of the outer shell. During use, the outer shell is placed on the ground through the support columns and the fixing plate. The syngas enters the inside of the separation component along the intake component. The separation component separates the impurities in the syngas. The separated syngas moves to the outside along the outlet pipe. By setting the intake component, the syngas is sent into the device. The intake component can preliminarily filter the syngas, reduce the large particle impurities in the syngas, prevent them from entering the subsequent separation component, and reduce the working burden of the separation component. By setting the separation component to filter the syngas, the separation component absorbs and filters the impurities in the syngas, and by combining multiple separation technologies, the efficiency and purity of impurity separation are improved.
[0009] Preferably, the intake component includes a fixed pipe. The top of the fixed pipe is fixedly connected to the bottom of the outer shell. A sliding column is slidably connected inside the fixed pipe, and a filtering component is fixedly installed inside the sliding column. During use, the syngas enters the inside of the sliding column and is preliminarily filtered by the filtering component to reduce the large particle impurities in the syngas. After the filtering component has been used for a long time, the sliding column can be separated from the fixed pipe, the sliding column removes the filtering component, and after cleaning and replacing the filtering component, the filtering component is reinstalled inside the intake component. By setting the intake component, the syngas is filtered, and the intake component is convenient to clean.
[0010] Preferably, the filtering component includes a filter plate. The outer side of the filter plate is fixedly connected to the inner side of the sliding column. A rotating rod is rotatably connected to the bottom of the filter plate, and a rotating blade is fixedly connected to the outer side of the rotating rod. During use, the filter plate preliminarily filters the syngas. When the syngas passes through the filtering component, it will drive the rotating blade and the rotating rod to rotate, and the rotating blade cleans the surface of the filter plate. By setting the filtering component, impurity accumulation is reduced, and the filter plate is prevented from being blocked by impurities.
[0011] Preferably, a ring pipe is fixedly connected to the top of the inner cavity of the intake pipe. A jet pipe is fixedly connected to the outer side of the ring pipe. A connecting pipe is fixedly connected to the bottom of the ring pipe. One end of the connecting pipe away from the ring pipe penetrates through the outer shell and extends to the outside. External nitrogen can enter the ring pipe through the connecting pipe and then be ejected from the jet pipe to blow back the sieve cylinder. Nitrogen passes through the activated carbon at a certain flow rate, and the adsorbed impurities are blown out. By setting the jet pipe to blow and regenerate the activated carbon, the service life of the adsorbent can be extended, the production cost can be reduced, and the continuous and efficient operation of the impurity separator can be ensured at the same time.

The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.
[0023] Please refer to Figures 1-6, the present utility model provides a technical solution: an impurity separator for syngas in ethanol preparation, including a housing 1; an intake assembly 2, an outlet pipe 4, and a bracket. The top of the intake assembly 2 is fixedly connected to the bottom of the housing 1. The intake assembly 2 is used for rough filtering of the syngas. The intake assembly 2 includes a fixed pipe 21. The top of the fixed pipe 21 is fixedly connected to the bottom of the housing 1. A sliding column 22 is slidably connected inside the fixed pipe 21. A filtering assembly 23 is fixedly installed inside the sliding column 22. There are mating flanges at the lower ends of the fixed pipe and the sliding column, and the two are fixed or separated by bolts on the flanges. The filtering assembly 23 includes a filter plate 231. The outer side of the filter plate 231 is fixedly connected to the inner side of the sliding column 22. A rotating rod 232 is rotatably connected to the bottom of the filter plate 231. A rotating blade 233 is fixedly connected to the outer side of the rotating rod 232. When in use, the syngas enters the inside of the sliding column 22 and is preliminarily filtered by the filtering assembly 23. When the syngas passes through the filtering assembly 23, it will drive the rotating blade 233 and the rotating rod 232 to rotate. The rotating blade 233 cleans the surface of the filter plate 231. By setting the filtering assembly 23, the accumulation of impurities is reduced, and the filter plate 231 is prevented from being blocked by impurities. After the filtering assembly 23 has been used for a long time, the sliding column 22 can be separated from the fixed pipe 21, the sliding column 22 removes the filtering assembly 23, and after cleaning and replacing the filtering assembly 23, the filtering assembly 23 is reinstalled inside the intake assembly 2. By setting the intake assembly 2, the syngas is filtered, and the intake assembly 2 is convenient to clean.
[0024] The bottom of the outlet pipe 4 is fixedly connected to the top of the housing 1.
[0025] The separation component 3 is fixedly installed in the inner cavity of the housing 1 and is used to filter impurities in the syngas. The separation component 3 includes an intake pipe 311 and a guiding pipe 32. The bottom of the intake pipe 311 is fixedly connected to the bottom of the inner cavity of the housing 1, the top of the intake pipe 311 is fixedly connected to the bottom of the guiding pipe 32, and the top of the guiding pipe 32 is fixedly connected to the top of the inner cavity of the housing 1. A molecular sieve 33 is fixedly connected to the inner side of the guiding pipe 32. A sieve cylinder 312 is slidably connected to the inner side of the intake pipe 311. A ring-shaped boss is provided inwardly at the bottom of the intake pipe 311, and the sieve cylinder 312 is placed through the boss to prevent the sieve cylinder 312 from falling out of the intake pipe. A top cover 313 is slidably connected to the top of the sieve cylinder 312, and activated carbon particles are provided inside the sieve cylinder 312. During use, the pre-filtered syngas enters the inside of the separation component upward. After being filtered by the activated carbon in the sieve cylinder, it then moves to the molecular sieve through the guiding pipe. The molecular sieve adsorbs and separates specific impurities in the syngas. By setting the separation component to separate impurities in the syngas, the molecular sieve and activated carbon are used in combination. The activated carbon can adsorb some larger molecules and non-polar impurities, while the molecular sieve can adsorb some small molecule impurities and specific polar impurities, thereby achieving a more comprehensive filtering effect. Among them, the top cover 313 of the sieve cylinder 312 can be opened. When the adsorption effect of the activated carbon is poor, the top cover can be opened to replace the activated carbon, which is convenient for replacing the adsorbent in the sieve cylinder.
[0026] Furthermore, a ring-shaped pipe 314 is fixedly connected to the top of the inner cavity of the intake pipe 311. A jet pipe 316 is fixedly connected to the outer side of the ring-shaped pipe 314. A connecting pipe 315 is fixedly connected to the bottom of the ring-shaped pipe 314. One end of the connecting pipe 315 away from the ring-shaped pipe 314 penetrates through the housing 1 and extends to the outside. External nitrogen can enter the ring-shaped pipe 314 through the connecting pipe 315 and then be ejected from the jet pipe 316 to backflush the sieve cylinder 312. The nitrogen passes through the activated carbon at a certain flow rate to blow out the adsorbed impurities. By setting the jet pipe 316 to blow and regenerate the activated carbon, the service life of the adsorbent can be prolonged, the production cost can be reduced, and the continuous and efficient operation of the impurity separator can be ensured.
[0027] The bracket includes a fixing plate 5 and 4 support columns 6. One support column 6 is fixedly connected to each of the four corners of the bottom surface of the fixing plate 5. Installation holes for the housing 1 are provided on the fixing plate, and the inner wall of the installation holes for the housing 1 is fixedly connected to the outer wall of the housing.
[0028] In use, the outer shell is placed on the ground through the support columns and the fixed plate. The syngas enters the separation component along the intake component. The separation component separates the impurities in the syngas. The separated syngas moves to the outside along the outlet pipe. By setting the intake component, the syngas is sent into the device. The intake component can preliminarily filter the syngas, reduce the large-particle impurities in the syngas, prevent them from entering the subsequent separation component, and relieve the working burden of the separation component. By setting the separation component, the syngas is filtered. The separation component absorbs and filters the impurities in the syngas. By combining multiple separation technologies, the efficiency and purity of impurity separation are improved.
[0029] Working principle:
[0030] In use, the outer shell 1 is placed on the ground through the support columns 6 and the fixed plate 5. The syngas is introduced through the intake component 2. The syngas enters the inside of the sliding column 22. The filter plate 231 preliminarily filters the syngas, reducing the large-particle impurities in the syngas. When the syngas passes through the filter component 23, it drives the rotating blades 233 and the rotating rod 232 to rotate. The rotating blades 233 clean the surface of the filter plate 231. After the filter component 23 has been used for a long time, the sliding column 22 can be separated from the fixed pipe 21. The sliding column 22 removes the filter component 23. After cleaning and replacing the filter component 23, the filter component 23 is reinstalled inside the fixed pipe 21. The preliminarily filtered syngas moves upward into the separation component 3. The syngas moves upward along the intake pipe 311 in the separation component 3. After being filtered by the activated carbon inside the sieve tube 312, the gas moves to the upper part of the separation component 3 and then moves to the molecular sieve 33 through the guiding pipe 32. The molecular sieve 33 adsorbs and separates specific impurities in the syngas. The separated syngas moves to the outside along the outlet pipe 4. After use, external nitrogen can enter the annular pipe 314 through the connecting pipe 315 and then be ejected from the jet pipe 316 to backflush the sieve tube 312. The nitrogen passes through the activated carbon at a certain flow rate, blowing out the adsorbed impurities. When the adsorption effect of the activated carbon is poor, the top cover 313 can be opened to replace the activated carbon.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special instructions and limitations.
