[0002] In the low-temperature shift COD elimination process, the condensate water from the low-temperature shift separator needs to be heated to about 80°C by a low-temperature shift gas heater, and then, together with the condensate water from the methanation gas-water separator and the sewage discharged from each boiler of the gas-making device, hydrogen peroxide is added for catalytic oxidation. The impurities in the sewage are eliminated, and finally, it is sent to the circulating water cooling tower through an independent pipeline for cooling, recovery and reuse.

Detailed implementation manners

[0027] The following will describe in detail some implementation manners of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] Please refer to Figures 1-6 , an embodiment of the present utility model provides a low-temperature shift condensate COD elimination device, including a housing 1. A first rotating rod 2 is rotatably provided at the upper end of the housing 1. The upper end of the first rotating rod 2 penetrates through the housing 1 and is connected to a first gear 3. A second gear 4 is rotatably provided on the upper side of the housing 1. The second gear 4 is driven by a motor. The first gear 3 meshes with the second gear 4 to rotate the first rotating rod 2.

[0029] The lower end of the first rotating rod 2 is connected to a hollow disc 5. At least three slide rails 6 are provided on the outer side of the hollow disc 5. A stirring assembly is slidably connected in the slide rails 6. The rotation of the first rotating rod 2 causes the whole stirring assembly to rotate to stir the liquid.

[0030] Among them, the stirring assembly includes a slider 14 slid in the slide rail 6. One side of the slider 14 is connected to a mounting block 15 through a connecting block. The connecting block is slidably connected to a chute 7 opened on one side of the slide rail 6. At the same time, a lead screw 8 is rotatably provided in the slide rail 6. One end of the lead screw 8 extends into the hollow disc 5. The lead screw 8 is driven by a motor. Since the lead screw 8 is threadedly connected to the slider 14, when the lead screw 8 rotates, the slider 14 drives the mounting block 15 to move, adjusting the stirring position of the whole stirring assembly to achieve the stirring effect from the outside to the inside.

[0031] Furthermore, a second rotating rod 9 is rotatably provided on the mounting block 15. The lower end of the second rotating rod 9 is connected to a frame 11. Symmetrical stirring members 13 are rotatably provided inside the frame 11. The stirring members 13 are driven by a motor. The rotation of the stirring members 13 further enhances the stirring effect on the liquid.

[0032] In addition, a plurality of stirring plates 12 are arranged on the outer side of the frame 11, and the stirring plates 12 stir the liquid on the outer side of the frame 11.

[0033] In order to satisfy the stirring of the upper liquid, a stirring blade 10 is arranged at the upper end of the second rotating rod 9, and the stirring blade 10 stirs the liquid at the upper end of the housing 1.

[0034] In order to realize the automatic rotation of the second rotating rod 9, the end of the second rotating rod 9 penetrates through the mounting block 15 and is connected to the third gear 16. A fourth gear 17 is rotatably arranged on one side of the mounting block 15. The third gear 16 meshes with the fourth gear 17, and the fourth gear 17 is driven by a motor. Since the second rotating rod 9 drives the frame 11 to rotate when rotating, and the frame 11 has a certain size, after a plurality of frames 11 are slid in the slide rail 6, the moving distance should not affect the rotation of the frame 11.

[0035] It should be noted that sealing covers are arranged on the outer sides of the motors installed inside the housing 1 to prevent the motors from entering the liquid and affecting their service life.

[0036] In summary, the working principle of a low-temperature shift condensate COD elimination device according to an embodiment of the present invention is as follows: the first rotating rod 2 drives the hollow disk 5 to rotate, so that a plurality of stirring components rotate to stir the liquid near the bottom of the housing 1. At the same time, in combination with the sliding of the slider 14 in the slide rail 6, the stirring position of the stirring components is adjusted, and in combination with the second rotating rod 9 driving the frame 11 to rotate, the purpose of stirring the housing 1 from the outside to the inside is satisfied, thereby improving the mixing effect of the catalyst and the liquid. And through the rotation of the stirring member 13 and the stirring of the liquid by the stirring plates 12, the stirring effect of the stirring components is further enhanced, and the effect of eliminating the COD of the low-temperature shift condensate is improved.

[0037] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
