Description

Technical Field

[0001] This utility model specifically relates to a boiler water treatment agent batching and feeding device, belonging to the field of boiler water treatment agent production technology. Background Technology

[0002] Boiler feedwater is drawn from tap water supplied by a water treatment plant. This water contains various impurities, such as suspended solids, oils, and calcium and magnesium salts that cause hardness. To remove and reduce these impurities and meet feedwater standards, the water entering the boiler needs to be treated with chemicals. In existing technologies, when preparing boiler water treatment agents, solid raw materials are first added to a production vessel, and a measured amount of water is added to the vessel through a feedwater device. The solid raw materials and water are then thoroughly mixed to obtain the boiler water treatment agent. Existing production vessel feedwater structures, such as the boiler water treatment agent disclosed in Chinese Patent Publication No. CN216630674U, are examples of such solutions. The boiler water treatment agent batching and water supply device ensures that the water flow from the nozzles is more dispersed during installation and use, facilitating the mixing and contact between the sprayed water and the raw materials in the mixing equipment, thus improving the uniformity of subsequent mixing operations. However, in the existing boiler water treatment agent production process, a fixed amount of water is added according to the weight of the solid raw materials of the boiler water treatment agent. But in actual production, factors such as the deviation in the weight of the solid raw materials added to the production vessel, the accuracy of the water metering valve, and the stability of the water supply system can easily lead to an imbalance in the ratio of solid raw materials and water, which can easily result in the boiler water treatment agent failing to meet quality standards. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a boiler water treatment agent batching and feeding device that can precisely supply water based on solid raw materials, thereby ensuring that the produced boiler water treatment agent meets quality standards.

[0004] The boiler water treatment agent dosing and feeding device of this utility model includes:

[0005] A controller for overall machine control, wherein the controller is connected to an initial water volume setting keypad;

[0006] The monitoring tank includes a tank body, a first metering valve is provided at the top of the tank body, a detection flange is provided in the middle of the tank body, and a mass transmitter is fixed on the detection flange; the mass transmitter is connected to the inside of the monitoring tank.

[0007] A water supply detection valve assembly includes a first tee connected to the bottom of the monitoring tank, a one-way valve connected to the bottom of the first tee, a second metering valve connected to the bottom of the one-way valve, and a water supply valve connected to the middle end of the first tee.

[0008] A water receiving unit, the water receiving unit including a water inlet flange connected to a water supply pipeline, the water inlet flange being connected to a pre-filter;

[0009] The first pump set is connected between the pre-filter and the second metering valve.

[0010] The second pump set has its output end connected to the first metering valve; its input end is connected to the production vessel; and the water supply valve is connected to the production vessel.

[0011] During production, according to the required component ratio, the set weight of solid raw materials is added to the production vessel. Then, based on the component ratio and the weight of the solid raw materials added, the theoretical water supply to the production vessel is calculated. The actual water supply is obtained by subtracting the adjusted water supply from the theoretical supply. Next, the actual water supply is sent to the controller via the initial water volume setting key. The controller sends an opening signal to the first pump group and the water supply valve. Water is metered by the second metering valve and pumped into the production vessel through the water supply valve. The solid raw materials and water are then thoroughly mixed in the production vessel. After a set mixing time, the second pump group starts, drawing a mixture of boiler water treatment agent from the production vessel. This mixture is metered by the first metering valve and pumped into the tank. The sample volume is then measured by the first metering valve. The concentration of the boiler water treatment agent in the tank is detected by a mass transmitter. If the concentration of the boiler water treatment agent in the tank is higher than the required concentration for the finished product, the water supply valve is closed, and the first pump group is started. The second pump group then pumps water through the second metering valve. The system includes a metering valve and a check valve. The first pump group pumps a fixed amount of water into the production vessel each time, intermittently opening the second metering valve. Each time the second metering valve is opened, the quality of the boiler water treatment agent is detected by a mass transmitter until the boiler water treatment agent reaches the finished product specifications, completing the adjustment process and counting the number of times the second metering valve is opened. The number of times the second metering valve is opened is multiplied by the amount of water added each time to obtain the total water volume tested. Next, based on the total amount of water entering the production vessel measured by the second metering valve and the amount of water sampled into the tank measured by the first metering valve, the total water volume is divided by the sample volume to obtain the sampling multiple. This sampling multiple is then multiplied by the total amount of the adjusting liquid to obtain the total ecological dosage added to the production vessel. Next, the total water volume added is subtracted from the set solid raw material sampling amount to obtain the actual total water volume added. The actual total water volume is then added to the production vessel via signals from the first pump group and the water supply valve. Following the above process, the concentration of the boiler water treatment agent produced in the production vessel is detected again until the concentration meets the standard.

[0012] Furthermore, the mass transmitter is at least one of a pH transmitter, a conductivity transmitter, or an indicator transmitter; the pH transmitter can detect the pH value of the mixture in the tank, the conductivity transmitter can detect the conductivity of the mixture in the tank, and the indicator transmitter can detect the concentration of the indicator in the mixture. A quantitative amount of indicator is added to the solid raw material according to the formula, and the concentration of the mixture can be indicated by the indicator.

[0013] Furthermore, a mixing motor is fixed to the top of the tank, and the output shaft of the mixing motor is installed with the stirring paddle inside the tank; the top of the stirring paddle blades is lower than the installation position of the mass transmitter; when the boiler water treatment agent that needs to be sampled in the tank is circulated and mixed with the pumped pure water, the mixing motor is turned on, and the stirring paddle is driven by the mixing motor to fully mix the mixture in the tank, and the mixture in the tank is detected by the mass transmitter.

[0014] Furthermore, the water supply valve is connected to the middle end of the second three-way valve, and the bottom of the second three-way valve is connected to the inside of the production vessel through an intermediate valve group; the top of the second three-way valve is connected to the input end of the second pump group; when it is necessary to supply water to the production vessel, or when it is necessary to re-inject the sampled boiler water treatment agent in the tank into the production vessel, the water supply valve is opened, and then the intermediate valve group is opened, so that the first pump group supplies water or the sampled boiler water treatment agent in the tank is pumped into the production vessel through the second three-way valve; when it is necessary for the sampled boiler water treatment agent in the tank to be circulated and mixed with the pumped pure water, the water supply valve is opened, the intermediate valve group is closed, and the second pump group and the first metering valve are opened, so that the sampled boiler water treatment agent can form a closed loop in the tank, the water supply valve, the second pump group and the first metering valve.

[0015] Furthermore, a third metering valve is installed on the top of the tank, which is connected to a high-level regulating tank. The high-level regulating tank stores regulating liquid; the regulating liquid has the same components as the boiler water treatment agent, and its concentration is greater than that of the boiler water treatment agent. The high-level regulating tank is also connected to the top of the tank via a metering pipeline. The boiler water treatment agent in the production vessel is pumped into the tank by a second pump set, and the amount is measured and sampled through the first metering valve. Then, the concentration of the boiler water treatment agent is detected by a mass transmitter. When the concentration of the boiler water treatment agent in the tank is lower than the required concentration of the finished product, the third metering valve is intermittently opened to measure the amount of regulating liquid added. This allows the regulating liquid to enter the tank. Each time the third metering valve is opened, the boiler water treatment agent concentration is increased. After the treatment agent and conditioning liquid are thoroughly mixed, the quality of the boiler water treatment agent is detected by a mass transmitter until the boiler water treatment agent reaches the finished product index, thus completing the conditioning process and counting the number of times the third metering valve is opened. The number of times the third metering valve is opened is multiplied by the amount of conditioning liquid added each time to obtain the total amount of conditioning liquid tested. Next, the total amount of water entering the production reactor is measured by the first metering valve, and the amount of sample entering the tank is also measured by the first metering valve. The total amount of water is divided by the amount of sample to obtain the sampling multiple, and the sampling multiple is multiplied by the total amount of conditioning liquid to obtain the total amount of conditioning liquid added to the production reactor. Then, the total amount of conditioning liquid added is subtracted from the set error to obtain the actual total amount of conditioning liquid added, which is then measured through the metering pipeline to respond to the actual total amount of conditioning liquid added to the tank.

[0016] Furthermore, the output end of the pre-filter is connected to the deionized water preparation unit, the output end of the deionized water preparation unit is connected to the temporary storage tank, and the temporary storage tank is connected to the input end of the first pump group; after the pre-filter filters the water in the water supply pipeline, it is sent to the deionized water preparation unit for secondary treatment to obtain deionized water, which is then stored in the temporary storage tank; then, the deionized water in the temporary storage tank is sent to the first pump group through the first pump group.

[0017] Compared with the prior art, the boiler water treatment agent batching and water supply device of this utility model sets the initial water supply volume through the initial water volume setting key, and after being fully mixed in the production tank, the boiler water treatment agent in the production tank is detected and adjusted through the monitoring tank, and the actual required water supply volume is calculated and accurately supplied to the production tank, thereby ensuring that the quality of the produced boiler water treatment agent meets the standards.
