Description

Technical Field

[0001] The present invention relates to the technical field of dehydrating agent production, and particularly to a composite sludge dehydrating agent prepared from organic waste acid and its production system. Background Art

[0002] The composite sludge dehydrating agent is an innovative chemical preparation. It is usually made from organic waste acid combined with a variety of raw materials through complex processes. Its composition contains specially treated wood powder, which undergoes a series of reactions such as alkalization under the action of sodium hydroxide, and also incorporates substances that contribute to flocculation such as cationic polyacrylamide and natural bamboo charcoal particles with adsorption functions. This dehydrating agent plays a key role in sludge treatment. It can effectively separate the water in the sludge through various mechanisms such as flocculation and adsorption, significantly improve the solid-liquid separation efficiency of the sludge, reduce the moisture content of the sludge, and can adsorb the odors emitted by the sludge during the dehydration process, reducing the adverse impact on the environment. It not only has good dehydration performance but also can meet the environmental protection requirements to a certain extent, providing an efficient and relatively environmentally friendly solution for the sludge treatment field and having a wide range of application prospects in related fields such as sewage treatment plants and industrial wastewater treatment.

[0003] During the production of this dehydrating agent, due to the need for the mixing of multiple raw materials and the need to slowly drip epichlorohydrin, the epichlorohydrin will be in the upper layer of the liquid surface in the dripping method. There is a situation where after the epichlorohydrin reacts with the raw materials in the upper layer, an isolation layer is formed and it cannot react fully with the raw materials under the isolation layer.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. By setting an etherification unit in the present invention, the baffle will periodically not block the first notch. When the baffle does not block the first notch, epichlorohydrin will flow out from the dropping port through the first notch and slowly drip into the heating pot in the form of water droplets, and react with diethylenetriamine and concentrated hydrochloric acid. In this way, the dropping speed and dosage of epichlorohydrin can be strictly controlled according to the reaction process, avoiding the situation that if the dropping speed is too fast, the reaction may be violent and even dangerous, and if the dropping speed is too slow, the reaction efficiency may be affected.

[0016] 2. By setting a liquid stirring unit in the present invention, during the rotation of the first rotating shaft, there will be a situation where the dropped epichlorohydrin enters the inflow port and then enters the inside of the stirring rod. As the epichlorohydrin accumulates in the stirring rod and reaches a certain weight, the sliding block will compress the telescopic spring, thereby driving the hook plate one to pull the hook plate two, and then the sealing plate will rotate, ensuring that epichlorohydrin can also come into contact with the bottom of the liquid and react.

[0017] 3. By setting a turning mechanism in the present invention, when the telescopic rod moves downward, the holding plate will drive the wood powder on the water surface to move towards the bottom of the liquid. At the same time, the second servo motor will drive the beaker to rotate, so that the liquid and the wood powder will rotate and mix to a certain extent.

[0018] 4. By setting a turning mechanism in the present invention, after mixing to a certain extent, the wood powder will gradually fuse with the liquid and flow through the round holes at the bottom of the holding plate to the top of the holding plate. Then, the two electromagnet magnetic blocks will generate magnetic forces in turn and cause the holding plate to rotate 180 degrees. After that, the telescopic rod will move downward again until all the mixture of wood powder and liquid can pass through the round holes. During the downward movement, the scraping ring will also scrape the wood powder adhering to the beaker and make it detach from the beaker wall. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0033] Example 1, using Figures 1-12 A composite sludge dewatering agent prepared from organic waste acid and its production system according to an embodiment of the present invention will be described as follows.

[0034] A composite sludge dewatering agent prepared from organic waste acid of the present invention, the raw material composition thereof includes: 30-60 parts of diethylenetriamine, 60-180 parts of concentrated hydrochloric acid, 75-125 parts of epichlorohydrin, 100-200 parts of wood powder, 50-100 parts of sodium hydroxide, 30-50 parts of cationic polyacrylamide, 50-100 parts of natural bamboo charcoal particles and appropriate pure water.

[0035] As Figures 1-2 shown, a production system for a composite sludge dewatering agent prepared from organic waste acid includes: a bottom plate 1, a support column 2 is fixedly connected to the top of the bottom plate 1, an operating table 3 is fixedly connected to the top of the support column 2, an etherification unit 4 is fixedly connected to the top of the bottom plate 1, a trachea 5 is fixedly connected to the top of the etherification unit 4, one end of the trachea 5 away from the etherification unit 4 is fixedly connected to a purification device 6, the bottom of the purification device 6 is fixedly connected to the top of the bottom plate 1, a liquid extraction pump 7 is fixedly connected to the outer surface of the etherification unit 4, one end of the liquid extraction pump 7 away from the etherification unit 4 is fixedly connected to an alkalization unit 8, and the bottom of the alkalization unit 8 is fixedly connected to the top of the bottom plate 1.

[0036] When the present invention works, the staff controls the overall equipment through the operating table 3. After adding appropriate raw materials into the etherification unit 4, the water extraction pump will extract the upper layer of etherifying agent and flow it into the alkalization unit 8. The purification device 6 will also adsorb the waste gas generated by etherification. Then, the alkalization unit 8 will mix and stir some raw materials such as wood powder with the etherifying agent, and finally form a dewatering agent.

[0037] As Figures 4-5As shown, the etherification unit 4 includes a first support base 41. A heating device 42 is fixedly connected to the top of the first support base 41. A heating pan 43 is fixedly connected to the top of the heating device 42. Support frames 44 are symmetrically arranged on the outer surface of the heating pan 43. An inlet one 45 is fixedly connected to the outer surface of the heating pan 43. An outlet pipe 46 is fixedly connected to the side of the heating pan 43 close to the liquid extraction pump 7. A top cover 47 is fixedly connected to the top of the heating pan 43. A stirring mechanism 48 is fixedly connected to the inner wall of the top cover 47. A liquid holding plate 49 is fixedly connected to the inner wall of the heating pan 43.

[0038] First, 30 - 60 parts of diethylenetriamine and 60 - 180 parts of concentrated hydrochloric acid are added to the heating pan 43 through the inlet. Then, 75 - 125 parts of epichlorohydrin are added through the second inlet 487. At the same time, the heating device 42 raises the temperature of the heating pan 43.

[0039] The bottom of the first support base 41 is fixedly connected to the top of the bottom plate 1. The bottom of the support frame 44 is fixedly connected to the top of the bottom plate 1.

[0040] As Figures 5-6 shown, the stirring mechanism 48 includes a first servo motor 481. The output end of the first servo motor 481 is fixedly connected to a first rotating shaft 482. A support ring 483 is fixedly connected to the top of the first rotating shaft 482. A first support rod 484 is fixedly connected to the bottom of the support ring 483. A baffle 485 is fixedly connected to the bottom of the first support rod 484. The bottom of the baffle 485 is slidably connected to the top of the liquid holding plate 49. A notch one 486 is arranged on the outer surface of the liquid holding plate 49. A dropping port 488 is fixedly connected to the bottom of the notch one 486. A second inlet 487 is fixedly connected to the outer surface of the liquid holding plate 49. Stirring units 489 are evenly arranged at the bottom of the first rotating shaft 482.

[0041] The first servo motor 481 first drives the first rotating shaft 482 to rotate at a certain speed, thereby driving the baffle 485 to rotate as well, so that the baffle 485 periodically does not block the notch one 486. When the baffle 485 does not block the notch one 486, the epichlorohydrin flows out from the dropping port 488 through the notch one 486 and slowly drips into the heating pan 43 in the form of water droplets, and reacts with the diethylenetriamine and concentrated hydrochloric acid. In this way, the dropping speed and dosage of the epichlorohydrin can be strictly controlled according to the reaction process, avoiding the situation that if the dropping speed is too fast, the reaction may be violent and even dangerous, and if the dropping speed is too slow, the reaction efficiency may be affected.

[0042] As Figures 7-9As shown in the figure, the liquid stirring unit 489 includes a stirring rod 4891. At the top of the stirring rod 4891, liquid inlets 4892 are evenly arranged. At the bottom of the stirring rod 4891, there is a notch two 4893. Inside the inner wall of the stirring rod 4891, a telescopic spring 4894 is fixedly connected. At the top of the telescopic spring 4894, a sliding block 4895 is fixedly connected. At the top of the sliding block 4895, a hook plate one 4896 is fixedly connected. On the outer surface of the notch two 4893, a sealing plate 4897 is rotatably connected. On the outer surface of the sealing plate 4897, a hook plate two 4898 is fixedly connected. The outer surface of the hook plate two 4898 abuts against the top of the hook plate one 4896.

[0043] With the rotation of the rotating shaft one 482, the stirring rod 4891 will also be driven to rotate, thereby appropriately stirring the mixed diethylenetriamine, concentrated hydrochloric acid, and epichlorohydrin. However, due to the different densities of the three, it is possible that the dripping epichlorohydrin is in the upper layer of the liquid surface and cannot be mixed with the other two. During the rotation of the rotating shaft one 482, there will be a situation where the dripping epichlorohydrin enters the liquid inlet 4892, and thus enters the inside of the stirring rod 4891. As the epichlorohydrin accumulates in the stirring rod 4891, when the weight reaches a certain amount, the sliding block 4895 will compress the telescopic spring 4894, thereby driving the hook plate one 4896 to pull the hook plate two 4898, and then the sealing plate 4897 will rotate, ensuring that the epichlorohydrin can also come into contact with the bottom of the liquid and react, thus ensuring the full contact of the three. After continuously dropping for 2 hours and then standing for a period of time, an etherifying agent will be formed on the upper layer.

[0044] The top of the servo motor one 481 is fixedly connected to the inner wall of the top cover 47, and the top of the stirring rod 4891 is fixedly connected to the outer surface of the rotating shaft one 482.

[0045] The specific working process is as follows:

[0046] During operation, first, 30 - 60 parts of diethylenetriamine and 60 - 180 parts of concentrated hydrochloric acid are added to the heating pot 43 through the pouring inlet. Then, 75 - 125 parts of epichlorohydrin are added through the pouring inlet 487. The servo motor 481 will first drive the rotating shaft 482 to rotate at a certain efficiency, thereby driving the baffle 485 to rotate as well, so that the baffle 485 periodically does not block the notch 486. When the baffle 485 does not block the notch 486, the epichlorohydrin will flow out from the dropping port 488 through the notch 486 and slowly drip into the heating pot 43 in the form of water droplets, and react with diethylenetriamine and concentrated hydrochloric acid. At the same time, as the rotating shaft 482 rotates, it will also drive the stirring rod 4891 to rotate, thereby appropriately stirring the mixed diethylenetriamine, concentrated hydrochloric acid, and epichlorohydrin. However, due to the different densities of the three, it is possible that the dripping epichlorohydrin is in the upper layer of the liquid surface and cannot be mixed with the other two. During the rotation of the rotating shaft 482, there will be a situation where the dripping epichlorohydrin enters the inlet 4892 and thus enters the inside of the stirring rod 4891. As the epichlorohydrin accumulates inside the stirring rod 4891 and the weight reaches a certain amount, the sliding block 4895 will compress the telescopic spring 4894, thereby driving the hook plate 4896 to pull the hook plate 4898, and then causing the sealing plate 4897 to rotate, ensuring that the epichlorohydrin can also come into contact with the bottom of the liquid and react.

[0047] Example 2, using Figures 1-12 A composite sludge dewatering agent prepared from organic waste acid and its production system according to an embodiment of the present invention will be described as follows.

[0048] As Figures 10-11 shown, on the basis of Example 1, the alkalization unit 8 includes a support base 81. The inner wall of the support base 81 is fixedly connected with a servo motor 82. The top of the support base 81 is fixedly connected with a water bath 83. The top of the water bath 83 is symmetrically provided with support rods 84. The top of the support rods 84 is fixedly connected with a support plate 85. The bottom of the support plate 85 is fixedly connected with a telescopic rod 87. The bottom of the support plate 85 is symmetrically provided with electromagnetic blocks 86. The bottom of the telescopic rod 87 is fixedly connected with a turning mechanism 88. One end of the water bath 83 close to the liquid extraction pump 7 is fixedly connected with a liquid inlet 89. The outer surface of the water bath 83 is fixedly connected with a water outlet 812. The output end of the servo motor 82 is fixedly connected with a rotating shaft 810. The top of the rotating shaft 810 is fixedly connected with a beaker 811.

[0049] The etherifying agent is pumped into the beaker 811 by the liquid pumping pump 7. Then, 100 to 200 parts of wood powder are taken and placed in the beaker 811. An appropriate amount of absolute ethanol is added and stirred evenly at room temperature to make the wood powder completely dispersed without caking. Weigh 50 to 100 parts of sodium hydroxide and completely dissolve it and pour it into the beaker 811. Water is added to the water bath 83 and the temperature is raised. Then, the turning mechanism 88 will turn the wood powder for 2 hours to achieve the effect of sufficient mixing.

[0050] As Figure 12 described, the turning mechanism 88 includes a support block 881. Symmetrically arranged on the outer surface of the support block 881 are third support rods 882. The bottom of the third support rod 882 is rotatably connected to a holding plate 883. Uniformly arranged on the outer surface of the holding plate 883 are round holes 884. Symmetrically arranged on the top of the holding plate 883 are magnetic blocks 886. Fixedly connected to the outer surface of the holding plate 883 is a scraping ring 885.

[0051] During these 2 hours of water bath heating and stirring, since the wood powder always floats on the water surface at the beginning and has strong adhesiveness after contacting water, the wood powder will adhere to the beaker 811. The telescopic rod 87 will move up and down. When moving downward, the holding plate 883 will drive the wood powder on the water surface to move towards the bottom of the liquid. At the same time, the second servo motor 82 will drive the beaker 811 to rotate, thereby causing a certain amount of rotation and mixing between the liquid and the wood powder. After mixing to a certain extent, the wood powder will gradually fuse with the liquid and flow through the bottom of the holding plate 883 through the round holes 884 into the top of the holding plate 883. As the telescopic rod 87 moves downward, the distance between the holding plate 883 and the electromagnet 86 will become closer. Then, the two electromagnets 86 will successively generate magnetic forces and respectively generate adsorption and repulsion forces on the two magnetic blocks 886, thereby causing the holding plate 883 to rotate 180 degrees. Then, the telescopic rod 87 will move downward again and push the wood powder to move downward further to mix with the liquid until all the mixture of the wood powder and the liquid can pass through the round holes 884. During the downward movement, the scraping ring 885 will also scrape the wood powder adhering to the beaker 811 and make it detach from the wall of the beaker 811.

[0052] After that, the heated water is drained through the water outlet 812, so that the beaker 811 reaches room temperature. Add 30 to 50 parts of cationic polyacrylamide and an appropriate amount of water to thicken it, and stir evenly at room temperature. The obtained product is allowed to stand and cool to obtain a brownish - brown viscous cationic dehydrating agent.

[0053] Finally, add 50 to 100 parts of natural bamboo charcoal particles and stir well to mix them so that the bamboo charcoal particles are evenly mixed inside the dehydrating agent, thus preparing the final finished dehydrating agent. Adding natural bamboo charcoal particles can adsorb the odor inside the sludge during dehydration, prevent the odor from spreading, and improve the working environment.

[0054] The bottom of the second support base 81 is fixedly connected to the top of the bottom plate 1. The top of the support block 881 is fixedly connected to the bottom of the telescopic rod 87. The outer surface of the scraping ring 885 is in contact with the inner wall of the beaker 811.

[0055] The specific working process is as follows:

[0056] During operation, the etherifying agent is pumped into the beaker 811 through the liquid pump 7. Then, 100 - 200 parts of wood powder are taken and placed in the beaker 811, and an appropriate amount of absolute ethanol is added. The mixture is stirred evenly at room temperature so that the wood powder is completely dispersed without caking. 50 - 100 parts of sodium hydroxide are weighed and completely dissolved and poured into the beaker 811. Water is added to the water bath 83 and the temperature is increased. When the telescopic rod 87 moves downward, the holding plate 883 will drive the wood powder on the water surface to move towards the bottom of the liquid. At the same time, the second servo motor 82 will drive the beaker 811 to rotate, thereby causing a certain amount of rotation and mixing between the liquid and the wood powder. After mixing to a certain extent, the wood powder will gradually fuse with the liquid and flow through the round hole 884 at the bottom of the holding plate 883 to the top of the holding plate 883. As the telescopic rod 87 moves downward, the distance between the holding plate 883 and the electromagnet 86 will become closer. Then, the two electromagnets 86 will sequentially generate magnetic forces and respectively exert attractive and repulsive forces on the two magnets 886, thereby causing the holding plate 883 to rotate by 180 degrees. Then, the telescopic rod 87 will move downward again and push the wood powder to move downward for further mixing with the liquid until all of the mixture of the wood powder and the liquid can pass through the round hole 884. During the downward movement, the scraping ring 885 will also scrape the wood powder adhering to the beaker 811 and make it break away from the wall of the beaker 811. 30 - 50 parts of cationic polyacrylamide and an appropriate amount of water are added for thickening, and the mixture is stirred evenly at room temperature. Finally, 50 - 100 parts of natural bamboo charcoal particles are added and fully stirred and mixed so that the bamboo charcoal particles are evenly mixed inside the dehydrating agent, and the final finished dehydrating agent is prepared.

[0057] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without making creative efforts shall fall within the protection scope of the present invention.
