[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Temperature sensor 2, temperature sensor 2 is used to monitor the temperature inside the drying equipment 1 in real time;

[0028] The pressure sensor 3 is used to monitor the pressure inside the drying device 1 in real time;

[0029] Humidity sensor 4, humidity sensor 4 is used to monitor the humidity inside the drying device 1 in real time;

[0030] Flow sensor 5, which is used to monitor the flow inside the pipeline in real time;

[0031] The controller 7 is used to collect data from the temperature sensor 2 , the pressure sensor 3 , the humidity sensor 4 and the flow sensor 5 . An adjustment mechanism 8 for adjusting the height of the controller 7 is provided on the back of the controller 7 .

[0032] Specifically, the output ends of the temperature sensor 2, pressure sensor 3, humidity sensor 4 and flow sensor 5 are electrically connected to the input end of the controller 7, and the output end of the flow sensor 5 is electrically connected to the flow control valve 6, which is used to control the flow of liquid in the pipeline. The monitoring ends of the temperature sensor 2, pressure sensor 3 and humidity sensor 4 are arranged inside the drying equipment 1.

[0033] Furthermore, the outer wall of the drying equipment 1 is connected with a pipeline, which is connected with the liquid storage tank through the pipeline. The liquid storage tank transmits the liquid to the interior of the drying equipment 1 through the pipeline through a water pump. The flow sensor 5 and the flow control valve 6 are both sleeved on the outer wall of the pipeline. The flow sensor 5 and the flow control valve 6 are respectively existing equipment. The flow sensor 5 is an existing non-contact electromagnetic flow sensor, and the flow control valve 6 is an electric ball valve. The temperature sensor 2, the pressure sensor 3 and the humidity sensor 4 are all existing equipment. The interior of the drying equipment 1 is provided with a heating device for heating. The outer wall of the drying equipment 1 is connected with a pressure relief pipe, and the outer wall of the pressure relief pipe is sleeved with a pressure valve. The pressure valve is an existing electric ball valve. The detection ends of the temperature sensor 2, the pressure sensor 3 and the humidity sensor 4 extend into the interior of the drying equipment 1. The temperature sensor 2, the pressure sensor 3 and the humidity sensor 4 are respectively fixed to the outer wall of one side of the drying equipment 1 by bolts. The temperature sensor 2, the pressure sensor 3, the humidity sensor 4 and the flow sensor 5 are all electrically connected to the controller 7 through wires, and the flow control valve 6, the pressure valve and the heating device are all connected to the controller 7. Through the wire connection, the controller 7 can set the numerical range for humidity, temperature, pressure and flow, so that when the controller 7 receives the data received by various sensors, it makes a numerical judgment to determine whether they are within the corresponding numerical range. When the flow is higher than the numerical range, the controller 7 controls the ball valve of the flow control valve 6 to rotate, reduces the flow area, and performs flow control. When the temperature is lower than the numerical range, the controller 7 starts the heating device to increase the temperature inside the drying device 1 until it reaches the temperature within the numerical range, and then stops the operation of the heating device. When the internal pressure of the drying device 1 is higher than the numerical range, the controller 7 controls the pressure valve to rotate and open, and discharges the internal pressure of the drying device 1 through the pressure relief pipe. A wireless transmission module is also provided inside the controller 7. When any data among the data is outside the numerical range for a long time, the wireless transmission module will send a signal to the wireless receiving device of the staff to remind and warn the staff and perform equipment maintenance, thereby achieving precise control of the drying process through automated and intelligent means to ensure the high purity and stability of hydrogen chloride.

[0034] Specifically, the adjustment mechanism 8 includes a moving block 83, and the moving block 83 is fixedly connected to a connecting plate 84 on the side facing the controller 7. The connecting plate 84 is used to be fixedly connected to the controller 7. A threaded groove is provided at the top of the moving block 83, and a rotating screw 82 is inserted and connected through the internal thread of the threaded groove. The outer portion of the rotating screw 82 is provided with a fixed box 81 for installing the rotating screw 82.

[0035] Furthermore, in order to facilitate on-site installation, the controller 7 can be conveniently installed on any suitable column through the clamp 9. The clamp 9 is an existing throat clamp, and two are symmetrically arranged in the vertical direction, which are respectively connected with the mounting holes of the fixed box 81. The clamp 9 is clamped on the outer wall of the column to fix the fixed box 81 and the column. The horizontal cross-sections of the moving groove and the moving block 83 are both T-shaped. The size of the moving block 83 is 0.98 times the size of the moving groove. The contact part between the moving block 83 and the connecting plate 84 is fixed by welding. The connecting plate 84 and the controller are fixed. The controller 7 is fixed with bolts, and the threads on the inner wall of the threaded groove are engaged with the threads on the outer wall of the rotating screw 82.

The top of the outer ring is welded and fixed to the top of the inner wall of the movable groove, and the inner wall of the inner ring is welded and fixed to the outer wall of the top of the rotating screw 82.
