Description

Technical Field

[0001] This utility model relates to the field of methanol purification technology, and more specifically, to a high-purity methanol purification device. Background Technology

[0002] Methanol is an organic compound and the simplest saturated monohydric alcohol, with the chemical formula CH3OH / CH4O. It has a molecular weight of 32.04 and a boiling point of 64.7℃. Methanol is also known as "wood alcohol" or "wood spirit," originating from its former primary production method of extraction from wood vinegar (a product of wood distillation or cracking). A current methanol purification tower includes a methanol tower, a cooler, and a methanol storage tank. The top of the methanol tower is connected to the cooler via a pipeline, and the cooler is connected to the methanol storage tank via another pipeline. Below the methanol storage tank, another pipeline connects back to the methanol tower via a reflux pump. The methanol tower includes a feed inlet, a packing layer, a condenser, a vapor outlet, and a liquid outlet. The feed inlet is located on the side of the methanol tower, the packing layer is located inside the tower, the condenser is located above the packing layer, the vapor outlet is located at the top of the tower, and the liquid outlet is located at the bottom.

[0003] Existing extraction devices require the collection to be full and then discharged when sampling and observing purified methanol. They cannot continuously collect methanol and must stop the extraction process. This results in a long processing time and no improvement in extraction efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-4 As shown, this utility model provides a high-purity methanol purification device, including a support frame 1, and a high-purity methanol purification auxiliary device 2 is provided at the upper end of the support frame 1. The high-purity methanol purification auxiliary device 2 includes a purification component 21 and a mixing auxiliary component 22, and the lower end of the purification component 21 is provided at the upper end of the support frame 1.

[0021] The purification component 21 includes: a distillation column 211, a distillation tee pipe 213, a condenser 215, a conveying pipe 216, a storage bin 2101, a sampling pipe 210, a reflux pipe 218, a discharge pipe 217, a discharge pipe 219, a feed pipe 212, and a distillation pipe 214. The lower end of the distillation column 211 is mounted on the upper end of a support frame 1, which has three sets. The lower end of the distillation tee pipe 213 is mounted on the upper end of the distillation column 211. The condenser 215, the conveying pipe 216, the storage bin 2101, the sampling pipe 210, the reflux pipe 218, the discharge pipe 217, the discharge pipe 219, and the distillation pipe 214 each have two sets, with one end of each set of distillation pipes 214 mounted on either side of the distillation tee pipe 213. At the end, the feed pipe 212 is set at the front end of the distillation column 211, the upper end of the condenser 215 is installed at the lower end of the conveying pipe 216, the front end of the condenser 215 is installed at the other end of the distillation pipe 214, the lower end of the condenser 215 is installed at the upper end of the storage chamber 2101, one end of the sampling pipe 210 is installed on the inner and outer walls of the side of the storage chamber 2101, and sampling ports are set at both ends of the upper side of the sampling pipe 210. The sampling pipe 210, the distillation tee pipe 213, the conveying pipe 216, the reflux pipe 218, the discharge pipe 217, the discharge pipe 219, the feed pipe 212 and the distillation pipe 214 are all equipped with switch control valves. There are two sets of purification components 21, and the two sets of purification components 21 are respectively set at the upper and lower ends of the two sets of storage chambers 2101.

[0022] The mixing auxiliary component 22 includes a drive motor 222, a rotating mixing rod 223, and an upper sealing cover 221. The lower end of the upper sealing cover 221 is installed on the upper end of the storage chamber 2101, and the upper end of the rotating mixing rod 223 is installed on the output end of the drive motor 222. The rotating mixing rod 223 is rotatably installed inside the storage chamber 2101.

[0023] The specific implementation method is as follows: When using this utility model, the device can transmit methanol through the distillation three-way pipe 213 at the upper end. When one end of the distillation three-way pipe 213 is open, methanol can be transmitted to the condenser 215 for condensation treatment. After the condenser 215 completes the treatment, methanol is stored in the storage chamber 2101 at the lower end. During storage in the storage chamber 2101, methanol can be mixed by the mixing auxiliary component 22 inside. After mixing, the operator can take out the methanol from the storage chamber 2101 through the sampling pipe 210 for sampling and testing. If the sampling is qualified, it can be discharged through the discharge pipe 219; if the sampling is unqualified, it can be discharged through the return pipe. The methanol flows back to the distillation column 211 through channel 218 for further purification. After the first set of storage chambers 2101 has completed its collection and testing, the methanol can be transferred to another component condenser 215 for separation by closing the control valve on one side of the distillation three-way pipe 213. This device improves the overall efficiency of the device by using two component condensers 215 for alternating collection and testing, avoiding the problem of long waiting times for a single collection device and the inability to continue collecting after it is full. Furthermore, the device uses a mixing auxiliary component 22 to mix and stir the methanol inside the storage chamber 2101, avoiding inaccurate test data caused by poor methanol stratification.

[0024] The working principle of this utility model is as follows: When using this utility model, the device can transmit methanol through the distillation three-way pipe 213 at the upper end. When one end of the distillation three-way pipe 213 is open, methanol can be transmitted to the condenser 215 for condensation treatment. After the condenser 215 finishes processing, it is stored in the storage chamber 2101 at the lower end. During storage in the storage chamber 2101, the methanol can be mixed by the mixing auxiliary component 22. After mixing, the operator can take out the methanol in the storage chamber 2101 through the sampling pipe 210 for sampling and testing. If the sampling is qualified, it can be discharged through the discharge pipe 219. If the sampling is unqualified, it can be returned to the distillation tower 211 through the return pipe 218 for further purification. After the collection and testing of one set of storage chambers 2101 is completed, the methanol can be transferred to another set of condensers 215 for separation treatment by closing the control valve on one side of the distillation three-way pipe 213. By setting up two sets of condensers 215 for alternating processing and collection, this device greatly improves the efficiency of the entire device.
