Description

Technical Field

[0001] This invention relates to the field of sodium acetate synthesis technology, specifically to an equipment and method for synthesizing sodium acetate from process wastewater. Background Technology

[0002] Currently, with the rapid development of industrialization, the treatment and resource utilization of process wastewater has become an important issue. One effective treatment method is to convert the organic matter in process wastewater into useful chemicals, such as sodium acetate, which can be obtained by reacting wastewater with acetic acid.

[0003] Before synthesizing sodium acetate from wastewater, the wastewater needs to be filtered. However, the wastewater contains too many impurities, which can easily clog the filter screen over time, thus affecting the filtration effect. In addition, the wastewater filter screen is inconvenient to clean and needs to be manually disassembled for cleaning. Therefore, it is necessary to develop a process wastewater sodium acetate synthesis equipment that can prevent filter screen clogging and make filter screen cleaning convenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device and method for synthesizing sodium acetate from process wastewater, which solves the problems of filter clogging affecting sodium acetate synthesis efficiency during long-term use of traditional process wastewater sodium acetate synthesis equipment, as well as the inconvenience of cleaning the filter.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a process wastewater sodium acetate synthesis equipment, comprising a synthesis tank, a horizontal beam horizontally arranged at the upper edge of one side of the synthesis tank, a filter box connected to the end of the beam away from the synthesis tank, a wastewater inlet arranged on the side of the filter box away from the beam, and a wastewater filter screen cylinder connected inside the filter box, a conveying pipe communicating with the bottom of the wastewater filter screen cylinder, the end of the conveying pipe away from the wastewater filter screen cylinder being located inside the synthesis tank, a stirring motor installed at the top of the synthesis tank, an agitator connected to the output shaft of the stirring motor located inside the synthesis tank, a partition plate arranged inside the synthesis tank below the conveying pipe, a reaction zone above the partition plate, and a discharge port arranged at the bottom of one side of the partition plate, the process wastewater sodium acetate synthesis equipment further comprising a wastewater filtration anti-clogging mechanism for preventing the wastewater filter screen cylinder from clogging and a sodium acetate screening mechanism for filtering sodium acetate solution.

[0006] The wastewater filtration anti-clogging mechanism includes an inlet pipe that rotates through the top of the filter box. The lower end of the inlet pipe rotates through the top of the wastewater filter screen and is connected to a limiting pipe inside the wastewater filter screen. Several nozzles are provided on one side of the limiting pipe inside the wastewater filter screen. The wastewater filtration anti-clogging mechanism also includes a main gear fixedly sleeved on the output shaft of the stirring motor, a movable sleeve that is laterally slidably sleeved on the outside of the crossbeam, and a gear disk that is rotatably set on the top of the synthesis box. The main gear meshes with the gear disk, and an eccentric rod is hinged at the upper edge of the gear disk. The end of the eccentric rod away from its hinge point is hinged to the upper part of the movable sleeve. A first drive gear is fixedly sleeved on the outside of the inlet pipe at the top position of the filter box. A first drive rack that matches the first drive gear is horizontally connected to one side of the movable sleeve. The first drive rack meshes with the first drive gear.

[0007] Preferably, the wastewater filtration anti-clogging mechanism further includes a movable seat that is longitudinally slidably sleeved outside the inlet pipe. A connecting rod is hinged to the side of the movable seat near the crossbeam, and the end of the connecting rod away from the movable seat is hinged to the side of the movable sleeve. A protruding rod is provided on the side of the movable seat away from the connecting rod, and a movable shaft is provided at the lower part of the end of the protruding rod away from the movable seat. The lower end of the movable shaft slides longitudinally through the top of the filter box and is connected to a scraper inside the filter box. The scraper is longitudinally slidably sleeved on the outer wall of the wastewater filter screen cylinder. When the scraper moves longitudinally, it scrapes off the impurities attached to the outer wall of the wastewater filter screen cylinder.

[0008] Preferably, the sodium acetate screening mechanism includes a feed inlet rotatably disposed at the lower end of the discharge port, and a sodium acetate filter screen cylinder is connected to the end of the feed inlet away from the discharge port. The bottom of the sodium acetate filter screen cylinder is open, and a base is installed at the opening by threads.

[0009] Preferably, the sodium acetate screening mechanism further includes a second drive gear fixedly sleeved on the outer wall of the feed inlet. A second drive rack is meshed on one side of the second drive gear. One end of the second drive rack slides laterally through the inner wall of the synthesis box and is connected to an L-shaped plate. A limiting sleeve is connected to the end of the L-shaped plate away from the second drive rack. The limiting sleeve is laterally slidably sleeved on the outside of the conveying pipe. A fixed shaft is connected to the upper part of the limiting sleeve. The end of the fixed shaft away from the limiting sleeve is connected to the bottom of the movable sleeve.

[0010] Preferably, a solenoid valve is installed on the discharge port.

[0011] A method for synthesizing sodium acetate from process wastewater includes synthesizing sodium acetate using a process wastewater sodium acetate synthesis equipment. The synthesis method includes the following steps:

[0012] S1. Wastewater is introduced into the wastewater inlet and enters the filter box. The wastewater filter screen inside the filter box filters the wastewater, leaving impurities on the outside of the filter screen. At the same time, the stirring motor is started, which drives the main gear to rotate. The main gear drives the gear disc that meshes with it to rotate. The gear disc drives the eccentric rod to move eccentrically. The eccentric rod drives the moving sleeve to move laterally on the crossbeam. When the moving sleeve moves laterally, it drives the connecting rod to move. The connecting rod causes the moving seat to move back and forth longitudinally on the inlet pipe. The moving seat causes the convex rod to move longitudinally on the moving shaft. The moving shaft causes the scraper to move longitudinally. When the wastewater filter screen filters the wastewater, the scraper will continuously scrape off the impurities attached to the outer wall of the wastewater filter screen to prevent the wastewater filter screen from becoming clogged.

[0013] S2. When it is necessary to clean the wastewater filter cylinder, water is introduced into the inlet pipe, the water enters the limiting pipe, and then sprays from the nozzle onto the inner wall of the wastewater filter cylinder to perform backwashing. At the same time as the moving sleeve moves, the moving sleeve will drive the first drive rack to move, the first drive rack will drive the first drive gear meshing with it to rotate, the first drive gear will drive the inlet pipe to rotate, the inlet pipe will drive the limiting pipe to rotate, thereby enabling backwashing of various positions on the inner wall of the wastewater filter cylinder.

[0014] S3. After the wastewater is filtered, it enters the reaction zone inside the synthesis tank through the conveying pipe. Acetic acid is added to the reaction zone. Under the operation of the stirring motor, the stirring motor drives the stirrer to rotate. The stirrer stirs the acetic acid and the filtered wastewater to increase the reaction rate between the wastewater and acetic acid, so as to generate liquid sodium acetate.

[0015] S4. After sodium acetate is generated, open the solenoid valve on the discharge port. Liquid sodium acetate enters the sodium acetate filter cylinder through the feed port. The sodium acetate filter cylinder filters the liquid sodium acetate, leaving the crystals inside the filter cylinder. When the moving sleeve moves, it drives the limiting sleeve at the lower end of the fixed shaft to move laterally back and forth on the conveying pipe. The limiting sleeve then drives the second drive rack at the lower end of the L-shaped plate to move laterally back and forth. The second drive rack drives the meshing second drive gear to rotate. The second drive gear then drives the sodium acetate filter cylinder at the lower end of the feed port to rotate, causing the liquid sodium acetate inside the filter cylinder to generate centrifugal force, throwing the liquid out, while the crystals remain inside the filter cylinder. Finally, open the base to obtain crystalline sodium acetate.

[0016] This invention provides an equipment and method for synthesizing sodium acetate from process wastewater, which has the following advantages compared with the prior art:

[0017] 1. The equipment and method for synthesizing sodium acetate from wastewater in this process, during the synthesis of sodium acetate, can drive the wastewater filtration and anti-clogging mechanism to work under the rotation of the stirring motor. This mechanism can not only backwash the wastewater filter screen, but also scrape the outer wall of the wastewater filter screen, making it less prone to clogging and ensuring smooth wastewater filtration. It also facilitates the cleaning of the wastewater filter screen.

[0018] 2. The equipment and method for synthesizing sodium acetate from wastewater in this process can also drive a sodium acetate screening mechanism under the operation of a stirring motor to screen the synthesized sodium acetate and screen out crystals. During screening, the sodium acetate filter cylinder can be continuously rotated to throw out the reaction solution and increase the crystal precipitation rate.

[0019] 3. The equipment and method for synthesizing sodium acetate from wastewater in this process uses a single stirring motor to drive multiple processes, saving economic costs and demonstrating strong interoperability. Attached Figure Description

[0043] S3. After the wastewater is filtered, the wastewater enters the reaction zone inside the synthesis tank 1 through the conveying pipe 5. Acetic acid is added to the reaction zone. Under the operation of the stirring motor 7, the stirring motor 7 drives the stirrer 10 to rotate. The stirrer 10 stirs the acetic acid and the filtered wastewater to increase the reaction rate of the wastewater and acetic acid, so as to generate liquid sodium acetate.

[0044] S4. After sodium acetate is generated, open the solenoid valve on the discharge port 11. Liquid sodium acetate enters the sodium acetate filter cylinder 96 through the feed port 95. The sodium acetate filter cylinder 96 filters the liquid sodium acetate, leaving the crystals inside. When the moving sleeve 65 moves, it drives the limiting sleeve 91 at the lower end of the fixed shaft 92 to move back and forth laterally on the conveying pipe 5. The limiting sleeve 91 then drives the second drive rack 94 at the lower end of the L-shaped plate 93 to move back and forth laterally. The second drive rack 94 drives the meshing second drive gear 98 to rotate. The second drive gear 98 then drives the sodium acetate filter cylinder 96 at the lower end of the feed port 95 to rotate, causing the liquid sodium acetate inside the sodium acetate filter cylinder 96 to generate centrifugal force, throwing the liquid out, while the crystals remain inside the sodium acetate filter cylinder 96. Finally, open the base 97 to obtain crystalline sodium acetate.

When the moving sleeve (65) moves, it will drive the limiting sleeve (91) at the lower end of the fixed shaft (92) to move back and forth laterally on the conveying pipe (5). The limiting sleeve (91) will then drive the L-shaped plate (93) to move back and forth. The second drive rack (94) at the lower end moves back and forth laterally. The second drive rack (94) drives the meshing second drive gear (98) to rotate. The second drive gear (98) will drive the sodium acetate filter cylinder (96) at the lower end of the feed port (95) to rotate, so that the liquid sodium acetate inside the sodium acetate filter cylinder (96) generates centrifugal force, which throws the liquid out, while the crystals remain in the sodium acetate filter cylinder (96). Finally, the base (97) is opened to obtain crystalline sodium acetate.
