Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to an online monitoring and analysis device for boiler water quality. Background Technology

[0002] Faced with the dual challenges of global resource scarcity and low-carbon transformation, optimizing the operating costs of steam boilers has become crucial for enterprises to improve economic efficiency and environmental sustainability. As a core component, real-time monitoring of boiler water quality (covering both feedwater and boiler water) plays a significant role in reducing energy costs. However, most of these devices are manually operated, requiring personnel to collect water samples and visually judge the color change after adding reagents to determine whether the water hardness is acceptable. This method of testing is highly subjective, leading to inaccurate results. Furthermore, the manual operation of the process prevents online monitoring, making it cumbersome, time-consuming, and labor-intensive. Therefore, this paper proposes an online boiler water quality monitoring and analysis device. Utility Model Content

[0003] The purpose of this invention is to provide an online monitoring and analysis device for boiler water quality to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring and analysis device for boiler water quality, comprising a cabinet, a cabinet door installed at the front end of the cabinet, and a touch screen installed inside the cabinet door; ventilation openings provided at the top and sides of the cabinet; a PLC processing module installed inside the cabinet, and a 4G transmission device installed on one side of the PLC processing module; two sets of detection water tanks installed inside the cabinet, and an inlet pipe installed on one side of each set of detection water tanks, with an electrically controlled valve installed on the inlet pipe; an outlet valve installed at the bottom of each set of detection water tanks; and a hardness sensor and a pH sensor installed inside each set of detection water tanks.

[0005] Preferably, each of the two sets of testing water tanks is equipped with a hardness controller and a pH controller at its top, and the hardness controller and pH controller are electrically connected to the hardness sensor and pH sensor, respectively.

[0006] Preferably, the hardness controller, the electric valve, and the pH controller are all electrically connected to the PLC processing module via wires.

[0007] Preferably, both the inlet pipe and the outlet valve are equipped with connection ports at their ends, and the connection ports are located at the bottom of the cabinet.

[0008] Preferably, a centrifugal pump is installed at the bottom of the cabinet, and an inlet is provided on one side of the centrifugal pump. An outlet is provided at the top of the centrifugal pump, and both the inlet and outlet are located on one side of the cabinet.

[0009] Preferably, a tri-color light is installed at the top of the cabinet, and both the tri-color light and the centrifugal pump are electrically connected to the PLC processing module via wires.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Equipped with a hardness controller, a detection water tank, an inlet pipe, an electric control valve, an outlet valve, and a pH controller, the system enables real-time monitoring of boiler water quality. The connection port can be connected to a delivery pipeline, allowing water from the boiler and water tank to be transported through the inlet pipe to the two detection water tanks. Hardness and pH sensors monitor the water in real time, and the data is displayed on a touchscreen in conjunction with the hardness and pH controllers. Opening the electric control valve allows the water in the detection water tank to flow back into the boiler and water tank, achieving water circulation. Simultaneously, a 4G transmission device sends the water quality data to a cloud server, thus improving the flexibility of use. The system is equipped with a three-color light, an input port, an output port, and a centrifugal pump to adjust the boiler water quality. The input port is connected to a high-alkalinity solution tank, and the output port is connected to the boiler water circuit. When the pH value of the boiler water is high, the PLC processing module will control the centrifugal pump to transport the liquid in the high-alkalinity solution tank to the boiler, thereby reducing the acidity value of the boiler water.
