Description

Technical Field

[0001] This utility model belongs to the field of environmental engineering technology, and specifically relates to a device for treating wastewater from the production of phthalocyanine blue. Background Technology

[0002] Phthalocyanine blue is an important organic pigment, and its production process generates a large amount of wastewater. Phthalocyanine blue production wastewater contains a variety of complex components, such as unreacted raw materials, byproducts generated during the reaction, and organic solvents. This wastewater originates from the chemical reaction steps in the synthesis of phthalocyanine blue, such as condensation reactions and refining processes, all of which produce wastewater. Due to its complex composition, the wastewater often has high concentrations of organic matter, high color intensity, and potentially toxic substances. This presents numerous challenges to the treatment of phthalocyanine blue production wastewater, requiring specialized treatment equipment to address these issues and meet environmental protection standards for discharge or reuse.

[0003] Currently, the wastewater from phthalocyanine blue production has a high color intensity, mainly due to the presence of pigment molecules and other colored substances remaining in the wastewater. Existing treatment devices, such as simple coagulation and sedimentation, can remove some of the color, but their effectiveness in treating high-color wastewater is limited. This is because these methods may only remove some of the larger colored particles through physical adsorption or simple chemical flocculation, while they are less effective at removing small-molecule colored substances dissolved in the wastewater. Utility Model Content

[0004] The purpose of this invention is to provide a device for treating wastewater from phthalocyanine blue production, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for treating wastewater from phthalocyanine blue production includes,

[0007] The treatment mechanism includes a water tank, an adsorption assembly disposed inside the water tank, and a water flow regulating assembly disposed outside the water tank.

[0008] The filtration mechanism includes a housing, a filter assembly disposed within the inner cavity of the housing, and a drain pipe fixedly installed on the outside of the housing.

The filter assembly intercepts solid particles that may carry chromatic substances, while the resin bed further removes ions or small organic molecules that affect color in the wastewater. The combined effect of these two components significantly improves the overall treatment efficiency for chromatic blue production wastewater. Attached Figure Description

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a device for treating phthalocyanine blue production wastewater, comprising:

[0029] The treatment mechanism 100 includes a water tank 101, an adsorption assembly 102 disposed inside the water tank 101, and a water flow regulating assembly 103 disposed outside the water tank 101.

[0030] The filtration mechanism 200 includes a housing 201, a filter assembly 202 disposed inside the housing 201, and a drain pipe 203 fixedly installed on the outside of the housing 201.

[0031] In the treatment unit 100, the adsorption component 102 performs preliminary adsorption treatment on organic matter, pigments, etc. in the wastewater. The water flow regulating component 103 ensures that the wastewater can fully contact the adsorption component 102 to improve the preliminary treatment effect. The first filter plate 202e and the second filter plate 202f in the filtration unit 202 intercept the remaining solid particles in the wastewater. The resin bed plate 202c performs further treatment such as ion exchange, so that the wastewater treatment process proceeds in an orderly manner. First, some pollutants are removed by adsorption, and then the wastewater is further purified by filtration and ion exchange, thereby improving the overall treatment capacity of the device for phthalocyanine blue production wastewater and ensuring that the final discharged wastewater meets better water quality standards.

[0032] Specifically, the adsorption assembly 102 includes a drive motor 102a fixedly installed on the outside of the water tank 101, a shaft 102b fixedly connected to the end of the drive motor 102a via an output shaft, a bushing 102c fixedly sleeved on the surface of the shaft 102b, a support frame 102d fixedly installed on the outer surface of the bushing 102c, a rotating rod 102e hinged in the inner cavity of the support frame 102d, a groove plate 102f fixedly sleeved on the outer surface of the rotating rod 102e, and a plurality of activated carbon adsorption columns 102g movably locked in the inner cavity of the groove plate 102f.

[0033] The activated carbon adsorption column 102g in the adsorption component 102 can effectively adsorb pollutants in wastewater. Activated carbon has a large specific surface area and rich pore structure, which can adsorb impurities such as organic matter and pigments in wastewater, thereby reducing the degree of wastewater pollution. The activated carbon adsorption column 102g is movably locked in the inner cavity of the tank plate 102f. This design facilitates the replacement or addition of activated carbon. When the activated carbon is saturated, the old activated carbon adsorption column can be easily removed and replaced with a new one, ensuring the continuity of the adsorption effect. The drive motor 102a drives the shaft 102b to rotate, which in turn causes the bushing 102c, support frame 102d, rotating rod 102e and tank plate 102f to move. This dynamic movement allows the activated carbon adsorption column 102g to continuously change position in the water tank 101, increasing the contact opportunity with wastewater and improving adsorption efficiency.

[0034] It should be noted that, in order to improve adsorption efficiency, a multi-stage series connection is adopted to increase the contact time and contact area between wastewater and activated carbon, ensuring more thorough removal of color. The packing density of activated carbon in the adsorption column is between 0.4 and 0.6 g / cm³, and the diameter of the 102g activated carbon adsorption column is 20 cm and the height is 80 cm, with an internal volume of approximately 25.12 liters. Based on a packing density of 0.5 g / cm³, the amount of activated carbon packed is approximately 12.56 kg. This achieves the adsorption capacity while ensuring normal water flow resistance.

[0035] Furthermore, the filter assembly 202 includes a base 202a fixedly installed in the inner cavity of the housing 201, guide rails 202b fixedly installed on both sides of the top of the base 202a, a resin bed plate 202c movably engaged with the inner surface of the guide rails 202b, a positioning frame 202d fixedly installed on the outer side of the guide rails 202b, a first filter screen plate 202e movably engaged with the inner cavity of the positioning frame 202d and close to the resin bed plate 202c, and a second filter screen plate 202f movably engaged with the inner cavity of the positioning frame 202d and away from the resin bed plate 202c. The filter assembly 202 also includes a threaded sleeve rod 202g fixedly installed on the top of the first filter screen plate 202e, a threaded rod 202h fixedly installed on the top of the resin bed plate 202c, and a rocker arm 202i fixedly installed at the end of the threaded rod 202h. The threaded sleeve rod 202g is threadedly connected to the outer surface of the threaded rod 202h.

[0036] The first filter plate 202e and the second filter plate 202f provide a multi-layer filtration structure, which can gradually intercept solid particles of different sizes in the wastewater, improve the filtration effect, and ensure that the final discharged wastewater is clearer. The first filter plate 202e and the second filter plate 202f are movably snapped into the inner cavity of the positioning frame 202d, making it easy to disassemble for cleaning or replacement. When blockage occurs, it can be cleaned in time to ensure smooth filtration. When the rocker arm 202i is manually turned, the threaded sleeve rod 202g will be driven to adjust the height on the surface of the threaded rod 202h, thereby adjusting the misalignment angle between the resin bed plate 202c and the first filter plate 202e. The position of the first filter plate 202e can be flexibly adjusted according to the wastewater treatment requirements to achieve misalignment of different pore sizes and optimize the treatment effect of filtration and ion exchange.

[0037] When in use, after wastewater enters the water tank 101, the adsorption component 102 inside the water tank 101 starts to work, the drive motor 102a starts, its output shaft drives the shaft 102b to rotate, the rotation of the shaft 102b causes the fixed bushing 102c to rotate accordingly, the support frame 102d also starts to move, the rotating rod 102e changes angle under the drive of the support frame 102d, the trough plate 102f moves with the movement of the rotating rod 102e, and the activated carbon adsorption column 102g can continuously change its position and angle inside the water tank 101;

[0038] Organic matter, pigments, and other pollutant molecules in wastewater are adsorbed by the active sites on the surface of the continuously moving activated carbon adsorption column 102g through physical and chemical adsorption. Physical adsorption is mainly due to the van der Waals forces between molecules, which cause small organic molecules and pigment molecules in the wastewater to adhere to the pore surface of the activated carbon. Chemical adsorption is due to the chemical reaction between the functional groups on the surface of the activated carbon and certain specific pollutant molecules in the wastewater, forming chemical bonds, thereby fixing the pollutants on the surface of the activated carbon.

[0039] After the wastewater enters the inner cavity of the tank 201, it first passes through the first filter plate 202e to intercept larger solid particles in the wastewater, such as incompletely dissolved raw material particles and larger impurities generated during the production process. After being filtered by the first filter plate 202e, the wastewater continues to flow to the resin bed plate 202c. The resin on the resin bed plate 202c has the function of adsorption or ion exchange for certain ions or small molecule organic matter in the wastewater. For some residual metal ions or specific organic pollutants in the wastewater, the resin can remove them through ion exchange or adsorption. The wastewater then passes through the second filter plate 202f. The mesh of the second filter plate 202f is smaller than that of the first filter plate 202e, which can intercept newly generated fine particles or impurities that have not been completely adsorbed by the resin in the wastewater after being treated by the resin bed plate 202c.

[0040] In summary, the treatment unit 100 and the filtration unit 202 ensure that the wastewater treatment process proceeds in an orderly manner. First, some pollutants are removed by adsorption, and then the wastewater is further purified by filtration and ion exchange, thereby improving the overall treatment capacity of the device for phthalocyanine blue production wastewater and ensuring that the final discharged wastewater meets better water quality standards.

[0041] Example 2

[0042] Reference Figure 1 and Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a method for regulating the water flow inside the water tank.

[0043] Specifically, the water flow regulating component 103 includes an arc plate 103a fixedly installed on the outside of the water tank 101, a servo motor 103b fixedly installed on the outside of the arc plate 103a, a through hole 103c opened on the surface of the water tank 101, a bracket 103d fixedly installed in the cavity of the through hole 103c, and a propeller 103e fixedly installed on the outside of the bracket 103d via an output shaft. The end of the servo motor 103b is fixedly connected to one end of the propeller 103e. The processing mechanism 100 also includes a water inlet pipe 104 fixedly installed on the outside of the water tank 101, and a control box 105 fixedly installed on the outside of the water tank 101. The filtration mechanism 200 also includes a conveying pipe 204 fixedly installed on the top of the housing 201. The conveying pipe 204 is used for communication between the water tank 101 and the housing 201.

[0044] The water flow regulating component 103 ensures that the wastewater can fully contact the adsorption component 102, thereby improving the treatment effect. Reasonable water flow regulation can avoid local dead zones where the water flow stagnates in the water tank 101, ensuring that the wastewater is effectively treated.

[0045] In use, the servo motor 103b can precisely control the rotation of the propeller 103e, and adjust the flow speed and direction of the wastewater in the water tank 101 by rotating the propeller 103e.

[0046] In summary, the water flow regulating component 103 ensures that the wastewater can fully contact the adsorption component 102, avoids water flow stagnation, and improves the treatment effect.
