[0027] A connecting frame 2 is connected to one side of the first unblocking column tube body 1, and a second unblocking column tube body 3 is connected to one side of the connecting frame 2.

[0029] In order to replace one layer of packing of the deobstruction column, the bolts on the sealing plate 4 are removed, and the sealing plate 4 is opened and pulled upward, driving the upper column 504 to pull the vertical tube 503 to move upward, and at the same time, the support 502 pulls the rubber plate 501 to clean the impurities on the inner wall of the first deobstruction column tube body 1, and the vertical tube 503 is pulled out of the first deobstruction column tube body 1. The rubber plate 501 and the support 502 support the vertical tube 503 to form a cavity under the vertical tube 503, so that the reactants of the impurity-removed compounds inside can be easily discharged to the second electric three-way valve 604.

The T-shaped cavity 507 is wide at the top and narrow at the bottom to prevent the filter screen 508 from falling off. Then the plug 506 is inserted into the through groove 505, and then the vertical cylinder 503 is placed in the first deobstruction column body 1, and the sealing plate 4 is fixed.

The first electronic pressure gauge 601 is connected to the upper side of the first unblocking column tube body 1, and the second electronic pressure gauge 602 is connected to the lower side of the first unblocking column tube body 1. The first electric three-way valve gauge 603 is connected to the upper side of the first unblocking column tube body 1 away from the first electronic pressure gauge 601, and the second electronic pressure gauge 602 is connected to the lower side of the first unblocking column tube body 1. A second electric three-way valve gauge 604 is connected to the lower part of a side of an unblocking column tube body 1 away from the second electronic pressure gauge 602. The first electronic pressure gauge 601, the second electronic pressure gauge 602, the first electric three-way valve gauge 603 and the second electric three-way valve gauge 604 are electrically connected to a PLC controller 605. The PLC controller 605 is connected to the front of the second unblocking column tube body 3. A speaker 606 is connected to the front of the connecting frame 2 near the bottom of the PLC controller 605. The speaker 606 is electrically connected to the PLC controller 605.

[0031] On the basis of the first embodiment, in order to realize automatic switching of the packing of the deobstruction column, according to the type of internal packing, the pressure difference threshold value between the first electronic pressure gauge 601 and the second electronic pressure gauge 602 is set for the PLC controller 605, and the first electronic pressure gauge 601 and the second electronic pressure gauge 602 detect the upper and lower pressures in the first deobstruction column tube body 1 in real time. When the internal packing is removed, impurities are left in the first deobstruction column tube body 1, and they are continuously accumulated to cause blockage. The reactants of the compound entering from the first electric three-way valve 603 are difficult to penetrate downward, causing the pressure of the first electronic pressure gauge 601 to increase continuously. If the pressure of the first electronic pressure gauge 601 is equal to When the pressure difference of the second electronic pressure gauge 602 reaches the threshold, it means that the internal filler is saturated or blocked, and the PLC controller 605 starts the first electric three-way valve gauge 603 and the second electric three-way valve gauge 604 to switch the flow path, and the reactants of the compounds entering the first deobstruction column body 1 enter the second deobstruction column body 3 to remove impurities and make a seamless connection.

The pressure difference threshold between the first electronic pressure gauge 601 and the second electronic pressure gauge 602 is set for the PLC controller 605. The reactants of the compound enter the first deblocking column tube body 1 from the filling device through the first electric three-way valve gauge 603 to remove impurities, and then enter the collection device from the second electric three-way valve gauge 604. When the pressure difference between the first electronic pressure gauge 601 and the second electronic pressure gauge 602 reaches a threshold value, the first electric three-way valve gauge 603 and the second electric three-way valve gauge 604 switch the flow path, and send the reactants of the compound into the second deobstruction column tube body 3 for impurity removal. At the same time, the PLC controller 605 prompts the replacement of the filler, and the speaker 606 issues a voice prompting the replacement. The sealing plate 4 is opened to take out the vertical cylinder 503, and the plug block 506 is pushed out to replace the internal fillers such as silica gel, quartz sand and activated carbon.
