Description

Technical Field

[0001] This invention relates to the field of ethanol drying and dehydration technology, and more specifically, to a circulating adsorption device used in the ethanol drying and dehydration process. Background Technology

[0002] In modern chemical production, ethanol is an important organic solvent and raw material, and is widely used in many fields such as medicine, chemical industry, and fuel.

[0003] Based on the above, the inventors have discovered the following problems: In current ethanol drying and dehydration production processes, the ethanol solution often contains a certain amount of water, which adversely affects its quality and subsequent performance. The presence of water may reduce the purity of ethanol, affecting its activity and stability in various chemical reactions, thus limiting the use of ethanol in high-end applications. Furthermore, the inability to quickly change the size of the discharge pipe in the ethanol drying and dehydration process causes inconvenience to workers and indirectly reduces dehydration efficiency.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a circulating adsorption device for the ethanol drying and dehydration process, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effectiveness of this utility model for a circulating adsorption device in the ethanol drying and dehydration process are achieved by the following specific technical means:

[0006] A circulating adsorption device for ethanol drying and dehydration includes an adsorption tower. The adsorption tower has a 5-mesh steel wire mesh inside. Several sets of ceramic saddle rings are installed at the top of the 5-mesh steel wire mesh. Molecular sieves are installed at the top of the ceramic saddle rings. A support plate is installed on one side of the adsorption tower. A raw material pump is installed at the top of the support plate. An output pipe is installed at the output end of the raw material pump, and an input pipe is installed at the input end of the raw material pump. A connecting block is installed on the inner wall of the adsorption tower. A connecting pipe is installed on one side of the connecting block. Several sets of discharge ports are installed at the bottom end of the connecting pipe, and a connecting mechanism is provided at the contact point between the connecting pipe and the connecting block.

[0007] Furthermore, the connecting mechanism includes a threaded hole, which is disposed on one side of the connecting block, and one side of the connecting pipe is threaded to the inside of the threaded hole. One end of the output pipe passes through the adsorption tower and is connected to the connecting block and the connecting pipe.

[0008] Furthermore, a vacuum pump is installed at the top of the adsorption tower, and a solenoid valve is installed at the bottom of the adsorption tower.

[0009] Furthermore, the adsorption tower is equipped with a cooling component for cooling the molecular sieve.

[0010] Furthermore, a nitrogen generator is installed on one side of the adsorption tower.

[0011] Furthermore, a control panel is provided on one side surface of the support plate, and the nitrogen generator, cooling assembly, vacuum pump, and raw material pump are all electrically connected to the control panel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By utilizing the connection between the connecting pipe, threads, threaded holes, and connecting block, operators can easily disassemble the connecting pipe through the threads and threaded holes and change the size of the discharge port as needed. The operation is very simple, which indirectly improves the dehydration efficiency of ethanol and greatly increases its practicality.

[0014] By designing a vacuum pump, the interior of the adsorption tower can be effectively kept under vacuum, which in turn can effectively promote the desorption of water from ethanol.

[0015] By designing a cooling component, the adsorbent is cooled after regeneration in the adsorption tower to prepare for the next batch of treatment, effectively improving subsequent adsorption operations. Attached Figure Description

[0026] This utility model provides a circulating adsorption device for the ethanol drying and dehydration process, including an adsorption tower 1. The adsorption tower 1 is equipped with a 5-mesh steel wire mesh 13 inside. Several sets of ceramic saddle rings 12 are provided at the top of the 5-mesh steel wire mesh 13. Molecular sieves 11 are provided at the top of the ceramic saddle rings 12. A support plate 4 is installed on one side of the adsorption tower 1. A raw material pump 8 is installed at the top of the support plate 4. An output pipe 7 is installed at the output end of the raw material pump 8. An input pipe 9 is provided at the input end of the raw material pump 8. A connecting block 17 is provided on the inner wall of the adsorption tower 1. A connecting pipe 15 is installed on one side of the connecting block 17. Several sets of discharge ports 16 are installed at the bottom end of the connecting pipe 15. A connecting mechanism is provided at the contact point between the connecting pipe 15 and the connecting block 17.

[0027] The connecting mechanism includes a threaded hole 18, which is located on one side of the connecting block 17. One side of the connecting pipe 15 is connected to the inside of the threaded hole 18 via a thread 3. One end of the output pipe 7 passes through the adsorption tower 1 and connects to the connecting block 17 and the connecting pipe 15. Through the cooperation between the connecting pipe 15, the thread 3, the threaded hole 18, and the connecting block 17, the operator can remove the connecting pipe 15 through the thread 3 and the threaded hole 18 when using the device, and change the size of the outlet 16 as needed.

[0028] The top of the adsorption tower 1 is equipped with a vacuum pump 2, and the bottom of the adsorption tower 1 is equipped with a solenoid valve 14. The design of the vacuum pump 2 can effectively maintain the vacuum state inside the adsorption tower 1, thereby effectively promoting the desorption of water from ethanol.

[0029] The adsorption tower 1 is equipped with a cooling component 10, which is used to cool the molecular sieve 11. The design of the cooling component 10 allows the adsorbent to be cooled after the adsorption tower 1 is regenerated, in preparation for the next batch of processing, which effectively improves the subsequent adsorption operation.

[0030] A nitrogen generator 6 is installed on one side of the adsorption tower 1.

[0031] The support plate 4 has a control panel 5 on one side surface, and the nitrogen generator 6, cooling component 10, vacuum pump 2, and raw material pump 8 are all electrically connected to the control panel 5.

[0032] The specific usage and function of this embodiment are as follows:

[0033] Before installation and use, personnel need to check that the equipment, pumps, instruments, etc. are in good condition, the system is clean and dry, water, electricity, steam cooling and nitrogen are normal, the raw material analysis indicators are normal, the molecular sieve 11 is filled in place and effectively fixed, and personnel wear appropriate personal protective equipment. At the same time, when using the device, the connecting pipe 15 can be removed through the thread 3 and threaded hole 18, and the size of the discharge port 16 can be changed as needed. The operation steps are very simple, which indirectly improves the dehydration efficiency of ethanol, and the design greatly increases its practicality. Then, the raw material pump 8 delivers ethanol to the inside of the adsorption tower 1. The vacuum pump 2 and nitrogen generator 6 are operated through the control panel 5, which can effectively maintain the vacuum state inside the adsorption tower 1, thereby effectively promoting the desorption of water from the ethanol. After desorption is completed, it can be discharged through the solenoid valve 14. Through the design of the cooling component 10, the adsorbent is cooled after the adsorption tower 1 is regenerated, preparing for the next batch of processing, which effectively improves the subsequent adsorption operation. If it needs to be used again, the above operation can be repeated.
