Description

Technical Field

[0001] The utility model relates to the technical field of crude alcohol dehydration, in particular to a crude alcohol dehydration device. Background Art

[0002] Focusing on the needs of environmental protection, resource conservation, comprehensive utilization and clean and low-carbon energy development, we carry out research on the development and application of technologies for the disposal of waste persistent organic pollutants products, and strive to solve the practical problem of recycling crude alcohol and turning waste into treasure, and avoid the direct incineration of crude alcohol to produce large amounts of emissions such as carbon dioxide and carbon monoxide; the existing water in crude alcohol can form azeotropes with C2-C5 alcohols, making the distillation and purification of crude alcohol extremely difficult. The water content of crude alcohol is about 10-45%. In order to realize the industrial application of the recycling of crude alcohol to produce new hydrogen and co-produce methanol, isopropanol and other low-carbon and environmentally friendly products, it is necessary to dehydrate the crude alcohol first.

[0003] At present, after crude alcohol is evaporated at high temperature, steam passes through a molecular sieve to discharge water molecules in the steam. Since the crude alcohol molecules are larger than the pore size of the molecular sieve, they are separated from the water molecules under the action of the molecular sieve, completing the initial dehydration of the crude alcohol. In the prior art, during the dehydration of crude alcohol, the pore size of the molecular sieve is blocked by a large number of crude alcohol molecules after being used for a period of time, thereby greatly reducing the efficiency of crude alcohol dehydration. In addition, a large amount of mixed steam is blocked, which can easily cause excessive air pressure in the device and lead to danger. The replacement or cleaning of the molecular sieve requires the suspension of the crude alcohol dehydration work. The dehydration work is continued after the molecular sieve is manually replaced or cleaned, and the dehydration efficiency is low. Utility Model Content

[0022] The storage tank 3 is provided to store the crude alcohol raw product, and the installation tank 11 is filled with a molecular sieve to remove the water in the crude alcohol. At the same time, the first collecting tank 5 and the second collecting tank 6 are provided to respectively collect the alcohol and water. The molecular sieve in the installation tank 11 is heated by the protective shell 7 and the electric heating tube 15 installed between the protective shell 7 and the installation tank 11 to clean the molecular sieve and reduce the blockage of the molecular sieve by the crude alcohol molecules. The crude alcohol dehydration pipeline is switched by the two groups of installation tanks 11 and the molecular sieve and through the connecting pipe 8 and the solenoid valve 10. The crude alcohol dehydration work does not need to be suspended during the cleaning of the molecular sieve to avoid affecting the efficiency of the crude alcohol dehydration work.

[0023] like Figure 2 and Figure 5 As shown, two groups of symmetrically distributed mounting rods 16 are provided in the mounting frame 2, the slider 17 is slidably sleeved with the mounting rod 16, a spring 18 is sleeved on the mounting rod 16, a cam 19 is provided in the mounting frame 2, a second motor 20 is provided on the mounting frame 2, two ends of the spring 18 are respectively fixedly connected to the slider 17 and the mounting rod 16, the cam 19 is rotatably connected to the mounting frame 2 through a rotating shaft, and the cam 19 is connected to the output end of the second motor 20 through a rotating shaft.

After the molecular sieve is used for a period of time, the crude alcohol molecules block the molecular sieve. At this time, the two groups of installation tanks 11 are switched through the electromagnetic valve 10 and the connecting pipe 8.
