Description

Technical Field

[0001] This invention relates to wastewater treatment, and more particularly to a chemical conditioning treatment device for boiler wastewater discharge. Background Technology

[0002] During the operation of industrial boilers, the wastewater discharged is typically characterized by complex composition, large pH fluctuations, and high suspended solids content. Direct discharge without effective treatment will cause serious environmental pollution. Currently, the treatment of boiler wastewater often employs equalization tanks for water homogenization and pH neutralization. However, the pH value of the wastewater generally exhibits a non-uniform distribution. Even within the same equalization tank, due to differences in the density of suspended solids, oils, and residual chemicals, significant stratification often occurs after settling, with significant pH differences at different depths. Existing wastewater treatment devices have many problems. Traditional equalization tanks are usually a single, integral structure, and most existing devices use a single-stage dosing method, injecting acidic or alkaline chemicals at a specific location within the equalization tank and relying on natural diffusion or simple agitation to mix the water throughout the tank. This approach cannot differentiate pH values ​​based on the actual pH levels at different water depths, easily leading to localized over-adjustment while other areas are under-adjusted, resulting in poor pH stability of the effluent. Traditional devices often directly add solid powders or high-concentration solutions into the tank. After entering the water, the powders quickly agglomerate and sink due to surface tension and density, forming "chemical clumps." Neutralization relies solely on slow molecular diffusion, resulting in long mixing times, low chemical utilization, and drastic local pH fluctuations, affecting treatment efficiency and the stable operation of subsequent processes. Most existing systems obtain pH values ​​through manual sampling and offline detection, which cannot acquire real-time pH distribution data at different water depths, nor can it immediately feed the detection results back to the dosing system. The lag between detection and adjustment means that the dosage relies on empirical estimation, resulting in low accuracy and significant chemical waste.

[0003] Therefore, it is necessary to develop a chemical conditioning and treatment device for boiler wastewater discharge that can accurately locate water stratification and differentiate pH adjustment, reduce chemical powder consumption and operating costs, and significantly improve the adjustment accuracy in order to solve the above problems.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a lifting mechanism to drive a pressure-type depth gauge and an electronic pH meter to move up and down at a uniform speed in the sewage. It can simultaneously record each depth and its corresponding pH value, and generate a data map of the number of water layers, the thickness of each layer and the pH value of each layer in the treatment unit. Based on this quantitative data, the control system can accurately calculate the pH value and dosage of the conditioning liquid required for each water layer, and spray the mixed conditioning liquid with a specific pH value to the designated water depth range through the output mechanism, so as to achieve precise neutralization of each layer and avoid the problems of over- or under-adjustment caused by overall adjustment.

[0015] 2. This invention is equipped with independent feeding, preparation, and mixing mechanisms, which can pre-prepare large quantities of acidic and alkaline conditioning solutions with constant pH values ​​and employ intermittent stirring to prevent sedimentation. During adjustment, the acid and alkaline conditioning solutions are simultaneously extracted according to the calculated ratio through two independently controlled electronically controlled flow valves, and then immediately output after secondary mixing by a high-speed motor and stirring impeller. Compared with directly adding powder or single liquid, this method results in more uniform mixing, faster reaction, higher proportioning accuracy, and significantly improved reagent utilization, avoiding problems such as powder agglomeration and localized overreaction when added to water.

[0016] 3. This invention uses precise calculations of the pH value and dosage of the conditioning solution based on actual measurement data, and adopts a layered fixed-point spraying method. The amount of reagent added is much lower than that of the traditional whole-dosing method, avoiding overdosing and ineffective dosing, effectively reducing reagent consumption and subsequent sludge production, and meeting the requirements of energy conservation, emission reduction and clean production. At the same time, the pre-configuration mode allows the configuration unit to continuously prepare conditioning solution during non-conditioning periods, avoiding the time loss of waiting for configuration and equipment idling, further saving energy consumption.

Each unit is equipped with an independent first and second electrically controlled valve, which can enable different units to be in different process states such as water inlet, settling, detection, regulation, and drainage. Each unit can operate in parallel without interfering with each other. At the same time, the electric circular slide rail and the electric linear slide rail drive the output mechanism to quickly switch between units, making full use of the settling waiting time, maximizing the utilization rate of the equipment, and shortening the overall processing cycle.

[0032] like Figure 2As shown, the water guiding mechanism 3 includes an inlet pipe 31, a first electrically controlled valve 32, a discharge pipe 33, and a second electrically controlled valve 34. An inlet pipe 31 is installed on the upper outer periphery of the regulating tank 1. The inlet pipe 31 is an annular pipe with a main valve, which connects to the external boiler wastewater output channel.

Each first electrically controlled valve 32 and each second electrically controlled valve 34 is an independently controlled solenoid valve structure.

[0033] like Figures 4-8 As shown, the lifting mechanism 9 includes a telescopic sleeve 91, a lifting frame 92, an extension rod 93, and an electric push rod 94. The telescopic sleeve 91 is installed at the front and rear positions on the left side of the extension frame 8. The telescopic sleeve 91 is a vertically oriented guide. The lifting frame 92 is installed at the lower end of the moving part of the telescopic sleeve 91. The output mechanism 10 and the detection mechanism 11 are located at the lifting frame 92. The extension rod 93 is installed in the middle of the upper side of the lifting frame 92. The electric push rod 94 is installed in the middle of the left side of the extension frame 8. The electric push rod 94 is vertically oriented, with its telescopic part facing upwards. The upper end of the moving part is connected to the upper end of the extension rod 93; when the electric push rod 94 is activated, the telescopic part of the electric push rod 94 will drive the extension rod 93 to move, thereby causing the extension rod 93 to drive the lifting frame 92 to move up and down through the telescopic sleeve 91, so that the lifting frame 92 drives the output mechanism 10 and the detection mechanism 11 to extend into the equalization tank 1, so that the detection mechanism 11 can detect the pH value at different depths in the equalization tank 1 and the pH value at its depth, so that the output mechanism 10 can output wastewater pH adjustment liquid with different pH values ​​at different depths in the equalization tank 1 to adjust and treat the wastewater.

[0034] like Figures 4-8As shown, the output mechanism 10 includes an output pipe valve 101, a high-speed motor 1011, a stirring impeller 1012, an electrically controlled flow valve 102, a liquid pump 103, and a hose 104. The output pipe valve 101 is installed in the middle of the left side of the lifting frame 92. The output pipe valve 101 is a solenoid valve. The high-speed motor 1011 is installed behind the output pipe valve 101. The stirring impeller 1012 is installed where the output shaft of the high-speed motor 101 extends into the output pipe valve 101. Electrically controlled flow valves 102 are installed on the lower sides of both the front and rear side walls of the lifting frame 92. The electrically controlled flow valves 102 are electromagnetic flow regulating valves. The input end of the output pipe valve 101 on the right side is connected to the output ends of the two electrically controlled flow valves 102 via a three-way connection. Liquid pumps 103 are installed at the front and rear positions of the lower right side of the extension frame 8. The output end of each liquid pump 103 is connected to a hose 104. The electric flow control valve 102 corresponding to the location is connected, and the input end of the pump 103 is connected to the configuration mechanism 13 corresponding to the location. The two pumps 103 respectively draw acidic pH adjustment solution and alkaline pH adjustment solution from the corresponding configuration mechanism 13 and input them into the connected electric flow control valve 102 through the hose 104. By controlling the opening of the two electric flow control valves 102, acidic pH adjustment solution and alkaline pH adjustment solution of different proportions are input into the output pipe valve 101. At the same time, the high-speed motor 1011 is started to make the stirring impeller 1012 mix the acidic pH adjustment solution and alkaline pH adjustment solution of different proportions to form a wastewater pH adjustment solution with a specific pH value. The mixed wastewater pH adjustment solution will be sprayed out from the output pipe valve 101 to adjust the pH value detected in a certain layer in the adjustment tank 1, so that the pH value of that layer is adjusted to a specific value.

[0035] like Figures 5-6 As shown, the detection mechanism 11 includes a pressure-type depth gauge 111 and an electronic pH meter 112. The pressure-type depth gauge 111 and the electronic pH meter 112 are installed on the rear side of the lifting frame 92. The pressure-type depth gauge 111 is used to measure the depth of the sewage that the lifting frame 92 extends into the regulating tank 1. The electronic pH meter 112 is used to measure the pH value at different depths in the regulating tank 1. By measuring the pH value of the sewage at a certain depth by the electronic pH meter 112, the opening of the two electrically controlled flow valves 102 can be precisely controlled, so that the acidic pH regulating solution and the alkaline pH regulating solution are input into the output pipe valve 101 at a specific flow rate for mixing, and forming a sewage pH treatment solution with a specific pH value for adjusting the pH value of the sewage at that depth, as well as the total amount of sewage pH treatment solution to be continuously sprayed.

[0036] like Figures 7-9As shown, the feeding mechanism 12 includes a storage bin 121 and a screw feeder 122. Storage bins 121 are installed at both the front and rear positions on the upper side of the movable frame 7. The storage bins 121 respectively store acidic and alkaline medicinal powders used for preparing acidic and alkaline pH adjusting solutions. The upper side of each storage bin 121 has a detachable sealing cover, which can close the storage bin 121 to prevent the medicinal powder inside from becoming damp and solidifying, and from being affected by external impurities. A screw feeder 122 is installed on the lower side of each storage bin, and each screw feeder 122 is independently controlled. When the screw feeder 122 is started, it outputs the medicinal powder from the storage bin 121 into the corresponding preparation mechanism 13.

[0037] like Figures 7-8 As shown, the configuration mechanism 13 includes a configuration pipe 131, an inlet valve 132, a feed hopper 133, and an outlet valve 134. Configuration pipes 131 are installed at both the front and rear positions of the lower side of the movable frame 7. Inlet valves 132 are installed on the upper side of each configuration pipe 131. Each inlet valve 132 is an independently controlled solenoid valve structure, and is connected to an external base liquid source for configuring acidic and alkaline pH adjusting solutions. A feed hopper 133 is installed on the left side of each configuration pipe 131, and the inlet of the feed hopper 133 is located at the corresponding screw feeder. Below the output port of machine 122, start the screw feeder 122. The screw feeder 122 feeds the powder in the output storage bin 121 into the corresponding configuration pipe 131 through the corresponding feed hopper 133. Each configuration pipe 131 is equipped with a liquid outlet valve 134. Each liquid outlet valve 134 is an independently controlled solenoid valve structure. The liquid outlet valve 134 is connected to the input end of the corresponding liquid pump 103. When the liquid outlet valve 134 is opened, the liquid pump 103 will draw acidic pH adjustment solution or alkaline pH adjustment solution from the configuration pipe 131.

[0038] like Figure 10 As shown, the mixing mechanism 14 includes a drive motor 141 and a stirring rack 142. The drive motor 141 is installed at both the front and rear positions on the left side of the movable frame 7. The stirring rack 142 is installed at the output shaft of the drive motor 141. The stirring rack 142 extends into the corresponding configuration tube 131. When the drive motor 141 is started, the drive motor 141 will drive the stirring rack 142 to rotate in the configuration tube 131 to mix the powder and base liquid input in the configuration tube 131.

[0039] like Figure 7 , Figure 8 and Figure 11As shown, it also includes a quantity control mechanism 15, which includes a cover frame 151, an elastic element 152, and a cap 153. Each feed hopper 133 has a quantity control mechanism 15 on its upper side. The quantity control mechanism 15 is used to further precisely control the output amount of the medicine powder from the screw feeder 122. Each feed hopper 133 has a cover frame 151 installed on its upper side. An elastic element 152 is installed on the left side of the inner wall of the cover frame 151. The elastic element 152 is a horizontally placed straight spring seat. A cap 153 is installed on the right end of each elastic element 152. All 3 are in contact with the discharge port of the screw feeder 122 corresponding to the position; the elastic element 152 uses its elasticity to block the discharge port of the screw feeder 122 with the plug cap 153. When the screw feeder 122 is started, the discharge port of the screw feeder 122 will output the powder, and the powder will push the plug cap 153 to the left under the output pressure of the screw feeder 122, and then the powder will be discharged; when the screw feeder 122 is stopped, the plug cap 153 will press the discharge port of the screw feeder 122 with its elasticity, so that the powder will not leak out due to residue.

[0040] Example 2, as Figures 1-11 As shown, the wastewater distribution method in the regulating tank 1 of the chemical regulating treatment device for boiler wastewater discharge is as follows: Boiler wastewater enters the inlet pipe 31 through an external channel. Then, the first electrically controlled valve 32 corresponding to each treatment unit separated by the partition layer 2 can be opened independently, allowing the wastewater to flow into one or more independent treatment units. The treatment units are not interconnected, achieving separate treatment based on quality or time. After one or more treatment units are filled with wastewater, the other first electrically controlled valves 32 are opened to introduce wastewater into other treatment units. The treatment units filled with wastewater then undergo a settling process, allowing the wastewater in these units to settle and stratify. Due to the different characteristics of the substances contained in the wastewater, different depth layers in this part of the unit in the regulating tank 1 have different pH values ​​after settling and stratification. The regulating tank 1 is divided into multiple independent units by the partition layer 2. Each unit controls the inlet and outlet of water through independent first electrically controlled valves 32 and second electrically controlled valves 34, respectively, so that wastewater is distributed to different units as needed. Each unit operates independently and can simultaneously perform different processes such as inlet, settling, detection, regulation, and outlet, improving the overall treatment efficiency.

[0041] This chemical conditioning and treatment device for boiler wastewater discharge uses a configuration mechanism 13 to pre-configure acidic and alkaline pH treatment solutions. Acidic and alkaline chemical powders for preparing the solutions are stored in two storage silos 121, respectively. Then, a screw feeder 122 is started, outputting the chemical powder from the storage silos 121 into the corresponding configuration pipe 131. Simultaneously, a base liquid is introduced into the configuration pipe 131 from the outside. The drive motor 141 is then started, causing the stirring frame 142 to rotate within the configuration pipe 131, mixing the chemical powder and base liquid. This creates acidic and alkaline pH treatment solutions with constant pH values ​​in the two configuration pipes 131. The drive motor 141 can then be controlled to operate intermittently, allowing the stirring frame 142 to mix the chemical powder and base liquid within the configuration pipe 131. The acidic and alkaline pH treatment solutions are intermittently stirred to prevent sedimentation. Acidic and alkaline powders are quantitatively fed into the preparation mechanism 13 via the feeding mechanism 12, where they are mixed with the external base solution and thoroughly stirred by the mixing mechanism 14 to form acidic and alkaline pH adjustment solutions with constant pH values. This allows for large-scale pre-mixing of the adjustment solution to meet continuous or sudden treatment needs, avoiding time delays caused by on-the-spot preparation, and ensuring a constant pH value for subsequent adjustments. Furthermore, the pre-mixing of the powder with the base solution, compared to the traditional method of directly sprinkling the powder into the pool, avoids this problem. In this method, the preparation mechanism 13 prevents the powder from rapidly agglomerating and settling due to surface tension and high density, forming "pharmaceutical clumps." Relying solely on natural diffusion results in a long mixing time, hindering rapid and uniform dispersion and causing drastic local pH fluctuations while other areas remain untreated, leading to low pesticide utilization.

[0042] The pH detection method of the chemical conditioning treatment device for boiler wastewater discharge is as follows: After the wastewater in one of the treatment units has settled and stratified, the movable frame 7, driven by the combined action of the electric circular slide rail 4 and the electric linear slide rail 6, moves the output mechanism 10 above the treatment unit. Then, the electric push rod 94 is activated, its telescopic component pushes the extension rod 93, causing the lifting frame 92 to descend vertically through the telescopic sleeve 91. This allows the output mechanism 10 and the detection mechanism 11 to extend into the wastewater and descend at a uniform speed to the bottom of the conditioning tank 1. Simultaneously, the pressure-type depth gauge 111 and the electronic pH meter 112 are activated. The pressure-type depth gauge 111 measures the water depth in real time, and the electronic pH meter 112 measures the pH value of the wastewater at its depth in real time. The measured water depth and the pH value of the corresponding depth layer are transmitted to an external computer control system. The depth and pH value changes determine the number of water layers, the height of each layer, and the pH value of each layer within the treatment unit. This data is then used to analyze the water volume of each layer within the treatment unit. Thus, the detection mechanism 11 can accurately digitize the wastewater condition within the treatment unit, providing a basis for precise pH adjustment. The lifting mechanism 9 drives the detection mechanism 11 to descend uniformly in the wastewater, simultaneously recording the water depth and its corresponding pH value. This generates a data map of the number of water layers, the thickness of each layer, and their corresponding pH values ​​within the unit. This transforms traditional experience-based judgments into precise data on water depth and pH, providing a quantitative basis for precise adjustment. The detection range covers the pool bottom to the water surface, ensuring no potential contamination layers are missed. Furthermore, the detection data can be transmitted to a computer system for subsequent automatic calculation of adjustment parameters, enabling intelligent control.

[0043] The wastewater conditioning process of the chemical conditioning treatment device for boiler wastewater discharge is as follows: Based on the aforementioned process of "pH value detection method of the chemical conditioning treatment device for boiler wastewater discharge", the measured wastewater data values ​​determine the pH adjustment sequence for each water layer. Then, based on the pH value, depth range, and water volume of a specific water layer requiring treatment, the external computer control system determines the required pH value and volume of the wastewater pH treatment solution for that layer. The opening amount and output duration of the two electrically controlled flow valves 102 are calculated. Subsequently, based on the data from the pressure depth gauge, the lifting mechanism 9 is controlled to drive the output mechanism 10 and the detection mechanism 11. The system extends into the water depth range of the wastewater. Then, based on calculated data, it controls the operation of two electrically controlled flow valves 102 and the connected pump 103. The pump 103 starts synchronously to extract acidic and alkaline pH treatment solutions from the connected configuration pipe 131, which are then fed into the connected electrically controlled flow valve 102 through the hose 104. This allows different proportions of acidic and alkaline pH adjustment solutions to be simultaneously fed into the output pipe valve 101. At the same time, the high-speed motor 1011 starts, causing the impeller 1012 to mix the different proportions of acidic and alkaline pH adjustment solutions, forming a wastewater pH adjustment solution that can be neutralized to a specific pH value according to the pH value of the water layer. The mixed wastewater pH... The pH adjusting solution will be sprayed from the output valve 101 to adjust the detected pH value of this layer in the equalization tank 1, bringing the pH value of this layer to a specific pH value. Simultaneously with the spraying, the electric annular slide rail 4 and the electric linear slide rail 6 can be controlled to work together, causing the movable frame 7 to move the spray valve in multiple directions within the treatment unit. This allows the spray valve to deliver the pH adjusting solution to multiple locations within the treatment unit until the spray volume reaches the required amount of pH adjusting solution based on the water volume of this layer. Then, the output mechanism 10 and the configuration mechanism 13 are closed. If the total volume in the configuration mechanism 13 is insufficient to support the required amount of pH adjusting solution for one application, acid adjustment can be performed again through the configuration mechanism 13. The preparation of acidic and alkaline pH treatment solutions: Based on test data, the computer calculates the required pH value and total amount of conditioning solution for a specific water layer. Two electrically controlled flow valves 102 are used to mix the acidic and alkaline pH conditioning solutions in proportion. The mixture is then further mixed by a high-speed motor 1011 and an impeller 1012, and sprayed through an output valve 101 to a designated water depth range. Simultaneously, the spray position is moved to cover the water surface of that layer. The pH value of the conditioning solution is designed for the target layer to avoid over- or under-adjustment, saving on chemical dosage. Precise proportioning and on-demand spraying prevent over-dosing and reduce operating costs. The spray nozzle can be moved during the spraying process to ensure full contact between the conditioning solution and the target water layer, improving reaction efficiency.

[0044] The circulating treatment process of the chemical conditioning treatment device for boiler wastewater discharge is as follows: After pH adjustment treatment of the water layer in the treatment unit, if turbidity still exists, the output mechanism 10 can be withdrawn after pH adjustment treatment of the water layer, allowing the water in the treatment unit to settle again. Then, the output mechanism 10 can be transferred to other treatment units that have already settled, and pH adjustment treatment of the wastewater in other settled treatment units can be performed as described in the above-mentioned "Water pH Value Detection Method of the Chemical Conditioning Treatment Device for Boiler Wastewater Discharge" and "Wastewater Conditioning Process of the Chemical Conditioning Treatment Device for Boiler Wastewater Discharge". Afterwards, for a treatment unit that has been treated with one or more layers and has been settled, wastewater pH adjustment treatment can be performed on other water layers in the treatment unit until pH adjustment is completed for all water layers in all treatment units. Then, a re-inspection can be performed through the detection mechanism 11, and the adjustment process described above can be repeated. Minor adjustments are made to some water layers. After adjustment, the second electrically controlled valve 34 corresponding to the treatment unit can be opened to discharge the pH-adjusted water in the treatment unit to the subsequent treatment tank. After emptying, the second electrically controlled valve 34 is closed, and the treatment unit can then receive subsequent sewage and perform pH adjustment as described above. After each adjustment, the mechanism is withdrawn to allow the water to settle and stabilize. During this period, it can be transferred to other units to continue operation. After settling, the other water layers in the unit are adjusted until all water layers in all units meet the standards. Finally, a re-inspection and fine-tuning are performed. Each adjustment is followed by a settling time to ensure that the neutralization reaction is fully completed and to avoid excessive mixing of the upper and lower layers due to agitation. The output mechanism 10 can be flexibly moved via the electric circular slide rail 4 and the electric linear slide rail 6 to make full use of the settling time and improve utilization. The final re-inspection ensures that the water quality of the effluent meets the standards. If there is any deviation, minor adjustments can be made to ensure the reliability of the treatment.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
