Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen peroxide production, and particularly relates to a working fluid dehydration device for hydrogen peroxide production. Background Art

[0002] The anthraquinone process for hydrogen peroxide production is one of the most mature production methods in the world. That is, a working fluid composed of diethyl anthraquinone, heavy aromatic hydrocarbons, trioctyl phosphate, etc. is hydrogenated under the catalysis of a catalyst, and then oxidized to form anthraquinone and hydrogen peroxide. Then, the hydrogen peroxide in the working fluid is extracted by pure water. The raffinate working fluid containing a certain amount of water is dehydrated and then enters the clay bed to regenerate the anthraquinone degradation products therein and re-hydrogenate for cyclic reaction.

[0003] In the dehydration process, if the internal and external environmental temperatures are both low or the material flows in the pipeline for a long time due to power failure, equipment failure, etc., the crystallization of carriers such as anthraquinone in the raffinate working fluid may cause pipeline blockage, resulting in the equipment being unable to operate smoothly. The existing method of using steam to heat the outer wall of the pipeline for blockage removal is relatively wasteful of steam, and the operators are easily scalded, with relatively large safety hazards.

[0035] Among them, in order to achieve the purpose of providing a movement space, the present device adopts the following technical solution: A housing 29 is fixedly connected to one side of the top of the fixed plate 2. One end of the second connecting rod 13 close to the wheel disc 14 is movably connected to one side of the housing 29 through a sealed bearing. A through groove 30 is formed on the surface of one side of the top of the fixed plate 2. The through groove 30 is located at the bottom directly below the housing 29. The function of the through groove 30 is to provide a movement space for the wheel disc 14 and the movable rod 16. The housing 29 can block the through groove 30 to prevent water leakage at the through groove 30;

[0036] Among them, in order to achieve the purpose of facilitating operation, the present device adopts the following technical solution: A hand wheel 31 is arranged outside the tower body 1. One end of the first connecting rod 7 away from the worm 3 extends out of the tower body 1 and is fixedly connected to the hand wheel 31;

[0037] Among them, in order to achieve the purpose of meeting functionality, the present device adopts the following technical solution: A steam outlet 32 is fixedly connected to the center of the top of the tower body 1. A working liquid inlet 33 is fixedly connected to one side of the top of the tower body 1. A working liquid outlet 34 is fixedly connected to the center of the bottom of the tower body 1. A support frame 35 is arranged at the bottom of the tower body 1. The top of the support frame 35 is fixedly connected to the tower body 1. The steam outlet 32 is used to connect to an external steam condenser, and the external steam condenser can be connected to a vacuum pump to provide negative pressure inside the tower body 1.

[0038] The usage process of the present invention is as follows: When using the present invention, the steam outlet 32 is used to connect to an external steam condenser, and the steam condenser is connected to a vacuum pump, so as to provide a negative pressure inside the tower body 1. Through the working fluid inlet 33, a raffinate working fluid containing a certain amount of water can be input into the tower body 1 from the outside. Under the condition of vacuum negative pressure, water is vaporized into steam and extracted through the steam outlet 32. The dehydrated raffinate working fluid is dispersed into a plurality of liquid pipes 9 and flows downward under the influence of gravity to be concentrated at the bottom of the tower body 1, and finally discharged through the working fluid outlet 34. Control valves are provided in the steam outlet 32, the working fluid inlet 33, and the working fluid outlet 34, which will not be elaborated here;

[0039] When the material flows inside the pipeline for a long time due to external factors, the user can rotate the handwheel 31 to drive the first connecting rod 7 to rotate. The first connecting rod 7 drives the worm 3 to rotate, so that the worm 3 drives the engaged worm wheel 5 to rotate. The worm wheel 5 drives the transmission rod 4 to rotate, and the transmission rod 4 drives the driving gear 8 at the bottom to rotate, thereby driving a plurality of driven gears 12 engaged with the driving gear 8 to rotate. The plurality of driven gears 12 respectively drive a plurality of liquid pipes 9 to rotate, so that the liquid inside the liquid pipes 9 flows downward in a spiral state. At the same time, when the worm 3 rotates, it drives the second connecting rod 13 to rotate. The second connecting rod 13 drives the disc 14 to rotate, and the disc 14 drives the first cylinder 15 to rotate. Since the top of the movable rod 16 is movably hinged to the first cylinder 15 and the bottom of the movable rod 16 is movably hinged to the second cylinder 20, when the disc 14 rotates, the connecting plate 19, the connecting block 18 and the connecting frame 17 can be pulled to move up and down reciprocally through the movable rod 16. The connecting frame 17 scrapes the water stains on the inner wall of the tower body 1 and drives a plurality of guide rods 21 to continuously slide up and down in the rod sleeves 22 and compress the springs 23, so as to drive a plurality of dredging rods 25 to enter the plurality of liquid pipes 9 through a plurality of supporting cross plates 24 to move up and down, so that a plurality of annular frames 26 slide up and down along the inner wall of the liquid pipes 9, effectively avoiding the crystallization and precipitation of the working fluid inside the liquid pipes 9, resulting in the blockage of the liquid pipes 9.

[0040] The above are only the preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention falls within the scope of protection required by the present invention.
