Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystallization fluidized bed technology, and in particular to an intelligent feedback automatic dosing system for crystallization fluidized beds. Background Technology
[0002] Crystallization fluidized bed technology is widely used in industrial wastewater softening, heavy metal removal and high-salt wastewater treatment. Its core is to generate easily precipitable particles through crystallization reaction, and then combine them with a fluidized bed to achieve efficient solid-liquid separation.
[0003] Existing fluidized bed crystallization dosing systems mostly use timed and quantitative or single parameter (such as pH value) feedback control. When in use, they face the problem that manual sampling and detection or single sensor monitoring cannot capture the dynamic changes in water quality in real time, resulting in a mismatch between the dosage and the actual needs. This can easily lead to waste of chemicals or insufficient reaction. Furthermore, fixed nozzles or single-point dosing can easily cause excessively high local concentrations of chemicals, affecting crystallization efficiency. Utility Model Content

[0023] Example 1 Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a power distribution cabinet with a protective mechanism, which can achieve precise dynamic control while improving the uniformity of reagent diffusion and crystallization efficiency. It includes a main unit 100, including a crystallization fluidized bed body 101. A water inlet 102 is provided on one side of the crystallization fluidized bed body 101, and a water outlet 103 is provided on the other side of the crystallization fluidized bed body 101. The water inlet 102 is connected to an external water inlet pipe through a flange for introducing water to be treated. The water outlet 103 is connected to a drainage pipe through a flange. The detection chamber 203 is used to install an integrated sensor 204. The detection unit 200 includes a housing 201 disposed on one side of the crystallization fluidized bed body 101, a reaction module 202 disposed on the housing 201, a detection chamber 203 disposed inside the outlet 103, and an integrated sensor 204 disposed inside the detection chamber 203. The housing 201 is connected to the outer wall of the crystallization fluidized bed body 101 by threaded fasteners. The reaction module 202 includes a data acquisition unit and a wireless transmitter disposed inside the compartment of the housing 201. The integrated sensor 204 includes a hardness sensor, a turbidity sensor, and a pH sensor disposed inside the detection chamber 203. The data acquisition unit and the wireless transmission module are connected to the hardness sensor, the turbidity sensor, and the pH sensor through waterproof cables. The hardness sensor, the turbidity sensor, and the pH sensor are in direct contact with the effluent flow. The dosing unit 300 includes a stirring component 301 disposed on the crystallization fluidized bed body 101, and a drug delivery component 302 disposed on the crystallization fluidized bed body 101. After the water to be treated enters the crystallization fluidized bed body 101 through the inlet 102, the detection unit 200 monitors the water quality data of the effluent in real time through the integrated sensor 204 (hardness, turbidity, pH) at the outlet 103. The data is then fed back to the dosing unit via the data acquisition device and wireless transmission module. The dosing amount is dynamically adjusted according to the water quality parameters, and the dosing unit 300 drives the dosing component 302 to accurately inject the agent into the fluidized bed. At the same time, the stirring component 301 operates synchronously to enhance the mixing and crystallization process of the agent and reactants. Finally, the treated water that meets the standards is discharged from the system through the outlet 103.
[0024] Example 2 Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the stirring component 301 includes a top cover 301a disposed on the upper end of the crystallization fluidized bed body 101. A motor 301b is disposed on the top cover 301a. An output shaft 301c is disposed at the output end of the motor 301b. A stirring blade 301d is disposed at the end of the output shaft 301c. The output shaft 301c is transmitted from the middle of the top cover 301a to the reaction zone. The output shaft 301c is covered with an anti-corrosion sleeve. The sleeve is fixed to the top cover 301a by a sealed bearing.
[0025] Motor 301b drives output shaft 301c to rotate stirring blade 301d. Output shaft 301c extends vertically into reaction zone through sealed bearing in the center of top cover 301a. It is covered with anti-corrosion sleeve to prevent corrosion from corrosive media. Stirring blade 301d forcibly stirs water flow in the lower part of reaction zone to promote uniform mixing of reagents and crystal nuclei and crystallization reaction.
[0026] The drug delivery component 302 includes a drug storage tank located on the ground outside the crystallization fluidized bed body 101. A metering pump is installed at the outlet of the drug storage tank. A diversion pipe 302b is installed on the crystallization fluidized bed body 101. A drug dosing pipeline 302a is installed at the upper end of the diversion pipe 302b. The drug dosing pipeline 302a is connected to the metering pump through a flange. A spherical connector 302c is installed at the lower end of the diversion pipe 302b. An upper nozzle 302d is installed on one side of the spherical connector 302c, and a lower nozzle 302e is installed on the other side of the spherical connector 302c. The upper nozzle is inserted into the upper part of the reaction zone, and the lower nozzle is inserted into the lower part of the reaction zone.
[0027] The metering pump draws the reagent from the storage tank and delivers it to the distribution pipe 302b via the flange-connected dosing pipeline 302a. The reagent is then distributed to the upper nozzle 302d (inserted into the upper part of the reaction zone) and the lower nozzle 302e (inserted into the lower part of the reaction zone) through the ball connector 302c, achieving precise stratified spraying of the reagent and using the shear force of the water flow to accelerate the diffusion of the reagent and its contact with the reactants in the fluidized bed.
