Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a device for treating grey water in an ammonia synthesis process. Background Art

[0002] In synthetic ammonia production, black water from the gasification process undergoes flash evaporation and sedimentation in the slag water treatment section, where solids and dissolved gases are separated to form gray water. After deoxygenation, the gray water is returned to the gasification process for recycling. During this production process, the black water from the gasification process contains a large amount of toxic and hazardous gases. Despite flash evaporation and sedimentation, some of these gases remain dissolved in the gray water. Therefore, gray water tanks are typically used to temporarily store the gray water. After the toxic and hazardous gases are removed from the gray water, the dust in the tanks is transported back to the gasification process for recycling.

[0003] The current method for treating the gray water in the gray water tank is to place the gray water tank somewhere in the factory, let the toxic and harmful gases in the gray water evaporate naturally, wait for a period of time for them to fully evaporate, and then transport the gray water to the gasification section for use. However, this treatment method is not only time-consuming, but also the toxic and harmful gases volatilized in the air can easily cause physical harm to workers or inspectors. Based on this, technicians have improved this treatment method: after the gray water is temporarily stored in the gray water tank, a waste removal agent that reacts with the toxic and harmful gases is added to it, and a stirring mechanism is equipped at the same time, and the stirring mechanism is used to fully mix the waste removal agent and the gray water for reaction; although this improved treatment method improves the treatment efficiency of the gray water, the sediments generated during this treatment process will adhere to the inner wall of the gray water tank, and the staff will need to periodically clean the inner wall later, which is time-consuming and labor-intensive, and the operation is relatively cumbersome, which indirectly reduces the treatment efficiency of the gray water.

The stirring mechanism in the treatment device not only has a stirring state for fully stirring and mixing the gray water and the waste removal agent, but also has a scraping state for cleaning the inner wall of the treatment cylinder. The two states can be switched according to the working conditions, so that the treatment device has the advantage of convenient impurity removal, which indirectly improves the treatment efficiency of the gray water.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0009] As a further solution of the present invention: the paddle and the telescopic member together form an adjustable paddle structure, and the adjustable paddle structure is provided in multiple forms and arranged in a circumferential array on the outer circumference of the rotating roller.

[0010] As a further solution of the present invention: the end of the paddle away from the rotating roller is detachably provided with a scraper strip, so that when the telescopic member is extended or shortened, the scraper strip can conflict with the inner wall of the processing cylinder.

[0026] The following will be combined with the accompanying 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] like Figure 1-Figure 5 As shown, a device for treating gray water in an ammonia synthesis process includes a treatment cylinder 1. The top of the treatment cylinder 1 is provided with a feed pipe 7 for feeding gray water, and a branch pipe 8 for feeding a waste removal agent. A drain pipe 9 for discharging gray water and the like is also provided at the bottom of the treatment cylinder 1. A stirring mechanism is provided on the treatment cylinder 1. After the gray water and the waste removal agent are added to the treatment cylinder 1, the stirring mechanism is used to mix the two, ensuring that the two are fully mixed and that toxic and harmful substances in the dust are removed more quickly.

[0028] In order to distinguish it from the conventional stirring mechanism, the stirring mechanism designed in the utility model has two working states. When it is in the first working state, the stirring mechanism stirs and mixes the ash water and the waste removal agent; when it is in the second working state, the stirring mechanism scrapes and cleans the inner wall of the treatment cylinder 1; the two working states can be switched according to actual usage, so that after the ash water waste removal is completed, there is no need to manually clean the inner wall of the treatment cylinder 1, thereby improving the cleaning efficiency.

[0029] The two designs of the stirring mechanism are shown as follows:

[0030] (1) The first design: The stirring device includes a driving motor 6, a rotating roller 2 and an arc-shaped paddle 3. The rotating roller 2 is rotatably arranged inside the processing cylinder 1, and the rotating roller 2 is arranged along the length direction of the processing cylinder 1. The driving motor 6 is fixedly arranged on the top of the processing cylinder 1, and the output shaft of the driving motor 6 is connected to the rotating roller 2 through a coupling transmission; a telescopic member 4 is provided on the outer circumference of the rotating roller 2, and the paddle 3 is hinged to the rotating roller 2 and the execution end of the telescopic member 4 respectively. At the same time, the paddle 3 and any cross section of the rotating roller 2 perpendicular to the axial direction are in an inclined arrangement state, and this state can be determined by Figure 3 To express.

[0031] When the telescopic member 4 is extended or shortened, the paddle 3 can rotate relative to the rotating roller 2, so that the paddle 3 can be in a cleaning working state in which it can contact the inner wall of the processing cylinder 1. Figure 2In the state shown, the telescopic member 4 is located at a position where the paddle 3 and the rotating roller 2 are arranged at an acute angle. At this time, the telescopic member 4 extends, so that the paddle 3 can come into contact with the inner wall of the processing cylinder 1. Subsequently, the rotating roller 2 is driven to rotate, so that the paddle 3 can scrape the attachments on the inner wall of the processing cylinder 1.

[0032] like Figure 3-Figure 4 As shown, specifically, the telescopic member 4 includes a connecting rod 401 fixedly mounted on the rotating roller 2 and a movable rod 402 hingedly mounted on the paddle 3. A sleeve 403 is rotatably provided on the connecting rod 401, and the sleeve 403 is arranged along the length direction of the connecting rod 401. An internal thread is provided inside the sleeve 403, and the movable rod 402 has a threaded section inserted into the sleeve 403 and adapted to the internal thread. The structure of this telescopic member 4 can be Figure 2 To express it. Figure 2 In the state shown, the staff rotates the sleeve 403 to make the movable rod 402 extend or retract in the sleeve 403. The corresponding movement of the movable rod 402 can drive the paddle 3 to rotate relative to the rotating roller 2, thereby achieving the interference between the paddle 3 and the inner wall of the processing cylinder 1.

[0033] (2) The second design: The difference between this design and the first design is that the telescopic member 4 has different structures in the two designs, such as Figure 5 As shown, specifically, the telescopic member 4 in this design includes a connecting rod 401 fixedly mounted on the rotating roller 2 and a movable rod 402 hingedly arranged on the paddle 3, a sleeve 403 is fixedly provided on the connecting rod 401, and the sleeve 403 is arranged along the length direction of the connecting rod 401, a bolt 404 is provided on the sleeve 403, and one end of the bolt 404 can pass through the sleeve 403, the movable rod 402 is inserted into the sleeve 403 and can be pressed by one end of the bolt 404. This telescopic member 4 structure can be made by Figure 5 To express it. Figure 5 In the state shown, the bolt 404 can be loosened first, and then the movable rod 402 can move in the sleeve 403 until the movement of the movable rod 402 drives the paddle 3 to contact the inner wall of the processing cylinder 1. At this time, the bolt 404 is tightened and the movable rod 402 is locked on the sleeve 403 using the bolt 404.

[0034] In both designs, the paddles 3 and the telescopic member 4 can be combined to form an adjustable paddle structure. Multiple paddles can be arranged in a circumferential array around the outer circumference of the rotating roller 2. When stirring is required, the rotation of the multiple paddles 3 thoroughly agitates the graywater and waste removal agent; when cleaning is required, the rotation of the multiple paddles 3 scrapes and cleans the inner wall of the treatment cylinder 1. This embodiment, by providing multiple paddles 3, can improve work performance and efficiency under the corresponding working conditions.

[0035] In order to avoid damage to the inner wall of the processing cylinder 1 when the paddle 3 is used to scrape, a scraper strip 5 can be detachably provided at the end of the paddle 3 away from the rotating roller 2, so that when the telescopic member 4 is extended or shortened, the scraper strip 5 can come into contact with the inner wall of the processing cylinder 1. After the scraper strip 5 is worn out, it can be removed and replaced with a new one. At the same time, when the interior of the processing cylinder 1 is set deeper, in order to prevent the scraper strip 5 on the stirring mechanism from being unable to completely scrape and clean the inner wall, the stirring mechanism of the utility model further includes a lifting member, which is used to drive the rotating roller 2 to move up and down inside the processing cylinder 1, so that the scraper strip 5 at the outer circumference of the rotating roller 2 can contact all parts of the inner wall of the processing cylinder 1 to achieve complete cleaning. It should be noted that the lifting member is set as a conventional mechanism in the prior art, which will not be described in detail herein.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
