[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, oxygen and water vapor discharged from the deaerator enter the inner cavity of the top cover. After the water vapor contacts the loop-shaped tube filled with coolant, it liquefies into water droplets, while the oxygen is still in a gaseous state and is collected and reused. When the crankshaft rotates to the lowest point, the closed cavity composed of the column cavity and the piston is in a negative pressure state. Then, under the action of the hydraulic pressure difference between the inner cavity of the loop-shaped tube and the inner cavity of the coolant tank, the coolant that has absorbed heat in the loop-shaped tube passes through the first one-way pipe assembly and converges into the coolant tank, recovering to the initial temperature. When the crankshaft rotates to the highest point, it causes The coolant in the closed cavity composed of the column cavity and the piston enters the coolant tank from the tank seat and is in a positive pressure state. At this time, the first one-way pipe assembly is in a closed state, and the second one-way pipe assembly is opened. The coolant at the initial temperature in the coolant tank passes through the second one-way pipe assembly into the loop pipe, replenishing the coolant at the initial temperature, maintaining the stable cooling effect of the loop pipe, improving the efficiency of liquefied water vapor, further separating oxygen and water vapor, and realizing the recycling of water vapor in the deaerator after liquefaction, thereby reducing the water consumption of the deaerator, reducing enterprise costs while saving water, and being more environmentally friendly.

[0020] 2. In the present invention, after the first belt rotates, the first driven pulley is driven to rotate, thereby driving the angle rod to rotate in the bracket, and the angle rod performs a circular motion with the connection with the bracket as the center. In the initial state, the middle part of the angle rod is located at the lowest point, and the plug plate contacts the first inductor. At this time, the first magnetic flux valve is in an open state, and the oxygen and water vapor discharged from the deaerator enter the input pipe through the first magnetic flux valve, and enter the inner cavity of the top cover through the through slit. At this time, the circular tube is filled with coolant, and the oxygen and water vapor are in contact with the return After the angled tube is inserted, water vapor liquefies into water droplets on the outer wall of the circular tube, while oxygen remains in a gaseous state. During the rotation of the middle part of the angled rod toward the highest point, the plug plate and the first sensor are separated, the first magnetic flux valve is closed, and the angled rod pushes the middle rod to move upward, thereby lifting the top rod, and then pushing the plug plate to move upward on the inner wall of the tank body. The oxygen and water vapor in the plug plate and the inner cavity of the tank body are all concentrated in the inner cavity of the top cover. At this time, the inner cavity of the top cover is in a pressurized state, which cooperates with the cooling of the coolant in the circular tube to increase the liquefaction speed of water vapor.

[0021] 3. In the present invention, when the angle rod rotates to the highest point, the plug plate contacts the second sensor, and the second magnetic flux valve opens at this time. The oxygen after liquefaction of water vapor is discharged through the output pipe and the second magnetic flux valve and collected, thereby improving the purity of the discharged oxygen. The liquefied water droplets drip, pass through the orifice plate, and accumulate on the surface of the plug plate. When the angle rod rotates to the lowest point, the plug plate and the second sensor are separated, and the second magnetic flux valve is closed. The angle rod pulls the middle rod, thereby pulling the top rod downward, and then pulling the plug plate to move downward on the inner wall of the tank body. When the plug plate begins to contact the reflux pipe, the water accumulated on the plug plate is discharged from the reflux pipe and reused in the deaerator, thereby realizing the recycling of water and reducing the water consumption of the deaerator.

[0039] In this embodiment, by starting the servo motor 21, the servo motor 21 drives the double wheel set 22 to rotate, and the double wheel set 22 drives the first belt 23 to rotate and then drives the first driven pulley 24 to rotate, thereby driving the angle rod 25 to rotate in the bracket 29, and the angle rod 25 performs a circular motion with the connection with the bracket 29 as the center. In the initial state, the middle part of the angle rod 25 is at the lowest point, and the plug plate 28 is in contact with the first inductor 5. At this time, the first magnetic flux valve 3 is in the open state, and the oxygen and water vapor discharged from the deaerator are discharged through the deaerator. The oxygen and water vapor enter the input pipe 4 through the first magnetic flux valve 3, and enter the inner cavity of the top cover 71 through the through slit 78. At this time, the loop tube 72 is filled with coolant. After the oxygen and water vapor contact the loop tube 72, the water vapor liquefies into water droplets on the outer wall of the loop tube 72, and the oxygen remains in a gaseous state. When the middle part of the angle rod 25 rotates to the highest point, the plug plate 28 and the first sensor 5 are separated, the first magnetic flux valve 3 is closed, and the angle rod 25 pushes the middle rod 26 to move upward, thereby pushing up the top rod 27, and then pushing the plug plate 28 to the tank body.

[0041] Embodiment 3

[0042] according to Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, the upper side of the tank body 11 is fixedly installed with the lower side of the top cover 71, the side wall of the top cover 71 is penetrated and fixedly connected with the two ends of the circular tube 72, one end of the circular tube 72 is fixedly connected with a hose 754, the other end of the hose 754 is fixedly connected with a ring tube 751, the inner wall of the ring tube 751 is fixedly connected with two groups of ring rods 752, the middle parts of the two ring rods 752 are slidably connected with a center rod 753, the outer surface of the center rod 753 is fixedly connected with a plug 755, one side of the plug 755 is clamped with the inner cavity of the ring tube 751, one side of the plug 755 is fixedly connected with a conical spring 756, the other end of the conical spring 756 is abutted with one side of one of the ring rods 752, the other end of the ring tube 751 is fixedly connected with a straight tube 757, the other end of the straight tube 757 is fixedly connected with one side of the box seat 714, and the structure of the second one-way tube assembly 76 is the same as that of the first one-way tube assembly 75.

[0043] In this embodiment, under the action of the hydraulic pressure difference between the inner cavity of the circular tube 72 and the inner cavity of the coolant tank 74, the plug 755 is forced to drive the center rod 753 to slide in the two ring rods 752 and compress the conical spring 756. At this time, the plug 755 is separated from the minimum inner diameter edge of the ring tube 751, and the coolant that has absorbed heat in the circular tube 72 passes through the gap between the ring tube 751 and the plug 755 and enters the straight tube 757, converges in the coolant tank 74, and recovers to the initial temperature. When the inner cavity of the coolant tank 74 is in a positive pressure state, the first one-way tube assembly 75 is in a closed state, and the second one-way tube assembly 76 is opened like the first one-way tube assembly 75. The coolant at the initial temperature in the coolant tank 74 passes through the second one-way tube assembly 76 into the circular tube 72 to replenish the coolant at the initial temperature.

[0044] The use method and working principle of the device: When the deaerator exhaust gas recovery device with recycling function is used, the exhaust port of the deaerator is connected to the first magnetic flux valve 3, and the oxygen and water vapor discharged after heating in the deaerator enter the first magnetic flux valve 3. First, the servo motor 21 is started, and the servo motor 21 drives the double wheel group 22 to rotate, and the double wheel group 22 drives the first belt 23 and the second belt 79 to rotate at the same time;

[0045] After the first belt 23 rotates, it drives the first driven pulley 24 to rotate, thereby driving the angle rod 25 to rotate in the bracket 29. The angle rod 25 makes a circular motion with the connection with the bracket 29 as the center. In the initial state, the middle part of the angle rod 25 is located at the lowest point, and the plug plate 28 contacts the first inductor 5. At this time, the first magnetic flux valve 3 is in the open state. The oxygen and water vapor discharged from the deaerator pass through the first magnetic flux valve 3 into the input pipe 4, and pass through the through slit 78 into the inner cavity of the top cover 71. At this time, the loop tube 72 is filled with coolant. After the oxygen and water vapor contact the loop tube 72, The water vapor liquefies into water droplets on the outer wall of the loop tube 72, while the oxygen remains in a gaseous state. When the middle part of the angle rod 25 rotates toward the highest point, the plug plate 28 and the first inductor 5 are separated, the first magnetic flux valve 3 is closed, and the angle rod 25 pushes the middle rod 26 to move upward, thereby lifting the top rod 27 upward, and then pushing the plug plate 28 to move upward on the inner wall of the tank body 11. The oxygen and water vapor in the plug plate 28 and the inner cavity of the tank body 11 are all concentrated in the inner cavity of the top cover 71. At this time, the inner cavity of the top cover 71 is in a pressurized state, which cooperates with the cooling of the coolant in the loop tube 72 to increase the liquefaction speed of the water vapor.

[0046] When the angle rod 25 rotates to the highest point, the plug plate 28 contacts the second sensor 6, and the second magnetic flux valve 9 opens. The oxygen after the liquefied water vapor is discharged through the output pipe 8 and the second magnetic flux valve 9 and collected, thereby improving the purity of the discharged oxygen.

[0047] The liquefied water droplets drip, pass through the orifice plate 73, and accumulate on the upper surface of the plug plate 28. When the angle rod 25 rotates to the lowest point, the plug plate 28 and the second sensor 6 are separated, the second magnetic flux valve 9 is closed, and the angle rod 25 pulls the middle rod 26, thereby pulling the top rod 27 downward, and then pulling the plug plate 28 to move downward on the inner wall of the tank body 11. When the plug plate 28 begins to contact the return pipe 10, the water accumulated on the plug plate 28 is discharged from the return pipe 10 and reused in the deaerator, so as to realize the recycling of water and reduce the water consumption of the deaerator.

[0048] The second belt 79 drives the second driven pulley 710 to rotate, and the second driven pulley 710 drives the crankshaft 712 to rotate inside the column housing 77, thereby driving the two sets of connecting rods 711 to move up and down, and then push the corresponding pistons 713 to move up and down on the inner wall of the corresponding through slot 78. When the crankshaft 712 rotates to the lowest point, the connecting rod 711 pulls the piston 713 to move downward on the inner wall of the through slot 78. At this time, the closed cavity composed of the column cavity 716 and the piston 713 is in a negative pressure state, and the coolant stored in the coolant tank 74 enters the column cavity 716 and the piston 713 from the through hole 715. 3, and the second one-way pipe assembly 76 is in a closed state at this time, thereby causing the inner cavity of the coolant tank 74 to be in a negative pressure state. Under the action of the hydraulic pressure difference between the inner cavity of the loop tube 72 and the inner cavity of the coolant tank 74, the plug 755 is forced to drive the center rod 753 to slide in the two ring rods 752 and compress the conical spring 756. At this time, the plug 755 is separated from the minimum inner diameter edge of the ring tube 751, and the coolant that has absorbed heat in the loop tube 72 passes through the gap between the ring tube 751 and the plug 755 and enters the straight tube 757, and converges into the coolant tank 74 to restore to the initial temperature;

[0049] When the crankshaft 712 rotates to the highest point, the connecting rod 711 pushes the piston 713 to move upward on the inner wall of the slit 78. At this time, the coolant in the closed cavity composed of the column cavity 716 and the piston 713 enters the coolant tank 74 from the box seat 714, and the inner cavity of the coolant tank 74 is in a positive pressure state. At this time, the first one-way tube assembly 75 is in a closed state, and the second one-way tube assembly 76 is opened like the first one-way tube assembly 75. The coolant at the initial temperature in the coolant tank 74 passes through the second one-way tube assembly 76 and enters the loop tube 72 to replenish the coolant at the initial temperature and maintain the stable cooling effect of the loop tube 72.
