[0025] Working principle: When the utility model is in use, hot gas is continuously delivered to the heat exchanger 2 through the heating gas input pipe 6. After the process gas passes through the defoaming net 8, the gas is discharged from the process gas discharge pipe 9 above, and the mist is collected on the defoaming net 8. After the mist gathers, it forms large-diameter droplets, which fall into other devices below. A part of the process gas delivered from the process gas delivery pipe 12 enters the interior of the shell 1 from the upper process gas input pipe 13, and the other part enters the interior of the shell 1 from the lower process gas input pipe 14. The process gas entering from the upper process gas input pipe 13 rises to the defoaming net 8 for gas-liquid separation. The separated liquid gathers and falls into the heat exchanger 2 below. The process gas entering from the lower process gas inlet pipe 14 contacts the liquid in the heat exchanger 2 in reverse. Under the heating effect of the heating gas outside the heat exchanger 2, the by-products in the liquid are separated, and the separated by-products are discharged from the process gas outlet at the top along with the process gas. The principle of separating the by-products in the liquid is as follows: for volatile substances that are miscible with water, such as methanol and ammonia, they are in a state of gas-liquid equilibrium in the process gas, but their concentration in the gas phase is greater than that in the liquid phase. The heat exchanger 2 is heated by the heating gas, and then the liquid inside the heat exchanger 2 is heated, and the liquid When the body temperature rises and is below the boiling point of the by-products, the equilibrium partial pressure in the liquid is broken, and the by-products in the liquid are enriched in the gas phase to achieve separation. The separated dripping liquid is collected in the inner cavity of the liquid collecting box 15. When the pressure sensor 16 detects that the water volume in the inner cavity of the liquid collecting box 15 reaches the set weight, a signal can be sent to the controller 17, and the controller 17 activates the alarm 18 to sound an audible alarm, thereby reminding the staff to deal with the liquid in the liquid collecting box 15 in time. At the same time, a signal is sent to the signal receiver 29 and the servo motor 28 is started. The servo motor 28 drives the first threaded rod 26 to rotate, and the first threaded rod 26 rotates. The rotation of a threaded rod 26 drives the two first threaded sleeves 25 to move horizontally relative to each other, and drives the two movable plates 22 to move relative to each other under the limiting action of the square rod 24, so that the two semicircular convex plates 23 push the adjacent fixed plates 21 to flip upward, and then drive the fan-shaped plates 19 to flip upward, so that the two fan-shaped plates 19 fit together horizontally, so that the groove 20 can be used to temporarily collect the dripping liquid, and then it is convenient for the staff to open the movable door 38 and take out the liquid collection box 15 to process the liquid collected therein, which effectively avoids liquid overflow and does not affect the normal operation of the separator, and is very convenient to use.

[0026] Embodiment 2:

[0027] The inner cavity of the transfer box 11 is provided with two baffles 30 distributed up and down, and the two baffles 30 are respectively arranged in contact with the upper process gas inlet pipe 13 and the lower process gas inlet pipe 14, and the same movable plate 31 is fixedly connected between the two baffles 30, and a second threaded sleeve 32 is fixedly penetrated at the middle position on the movable plate 31, and a second threaded rod 33 is screwed into the inner cavity of the second threaded sleeve 32, and a second sealed bearing is fixedly connected to the right side of the transfer box 11, and the right end of the second threaded rod 33 penetrates the inner cavity of the second sealed bearing, and is fixedly connected with a driven groove wheel 34, a belt 36 is provided between the transmission groove wheel 35 and the driven groove wheel 34, and the transmission groove wheel 35 and the driven groove wheel 34 are connected by the belt 36 for transmission, and perforations are opened near the top and bottom of the movable plate 31, and a cross bar 37 is penetrated through the inner cavity of the perforation, and the right ends of the two cross bars 37 are fixedly connected to the right side wall of the inner cavity of the transfer box 11, so as to improve the stability of the horizontal movement of the movable plate 31.

[0028] Working principle: When the utility model is in use, when the servo motor 28 is working and temporarily closes the inner cavity of the shell 1, the first threaded rod 26 rotates to drive the transmission groove wheel 35 to rotate, and the transmission groove wheel 35 rotates through the belt 36 to drive the driven groove wheel 34 to rotate, and the driven groove wheel 34 rotates to drive the second threaded rod 33 to rotate, and the second threaded rod 33 rotates to drive the second threaded sleeve 32 to move right, and drive the movable plate 31 to move horizontally to the right. The rightward movement of the movable plate 31 can drive the two baffles 30 to move horizontally to the right, thereby partially blocking the upper process gas inlet pipe 13 and the lower process gas inlet pipe 14 respectively, thereby reducing the temporary input flow of the process gas, and avoiding the liquid in the liquid collection box 15 from overflowing to the outside of the shell 1 due to the long time of cleaning the liquid.
