Overview

The automatic dosing device of the boiler automatically proportions the concentration of the chemical solution and performs automatic dosing based on the control signal output by the upper system during automatic control. At the same time, the liquid level height, drug concentration, system pressure, drug dosage and other parameters of the phosphate dosing device can be uploaded to the upper system through PLC, and remote real-time monitoring and control can be achieved by the upper system.

Product Details

The automatic dosing device for boilers can be divided into three types based on the different detection signals from the primary instrument: a fully automatic coagulant dosing system controlled by floating current, an automatic acid-base adjustment device controlled by pH meter, and a fully automatic circulating cooling water dosing system controlled by conductivity. The control system can adopt manual/automatic control. In automatic control, based on the control signal output by the upper system, the concentration of the medicine is automatically proportioned and added. At the same time, the liquid level height, drug concentration, system pressure, drug dosage and other parameters of the phosphate dosing device can be uploaded to the upper system through PLC, and remote real-time monitoring and control can be achieved by the upper system. Water is drawn into the solution tank by a water injector, and then added to the tank in proportion to mix evenly with desalinated water or condensate water. It is then added to the boiler condensate water or feedwater through a metering system. The dosing control can be done manually or automatically based on the control signal output by the upper system.

Specification and configuration of boiler automatic dosing device:

The dosing device is mainly composed of a metering pump as the main dosing equipment, which assembles the dissolving tank, agitator, level gauge, safety valve, check valve, pressure gauge, filter, buffer, pipeline, valve, base, escalator, automatic monitoring system, power control system, etc. on a common platform according to the process requirements, forming a module called the "pry mounted combination unit". A certain amount of medication is put into the mixing solution tank for stirring and dissolution as needed, and after dissolution, it is sent to the dosing point through the metering pump. The size of the dosing amount can be freely adjusted to meet the needs of different dosing places. The entire system adopts detection instruments, accurate measurement, and reliable operation. The main function of the complete device is to... Including feeding system, storage tank, dosing system, power control system, etc.

Several key points of boiler water quality management:

1. Water treatment equipment: Reliable soft water treatment equipment should be used. For boiler rooms with particularly poor boiler feedwater quality, an external automatic dosing device should be installed, and scale inhibitors should be automatically added in a timely manner based on water quality monitoring;

2. Manual testing: According to the requirements of "Industrial Boiler Water Quality" (GBT 1576-2008), real-time monitoring of the concentration of calcium and magnesium ions in boiler feedwater and boiler water is carried out to ensure that the boiler feedwater water quality meets the standard;

3. Remote management: Using the Internet of Things platform to monitor boiler scale, the principle is to use the Internet of Things platform to record changes in boiler exhaust gas temperature, combined with comprehensive data analysis of boiler water temperature and combustion load, to determine the scale condition, guide scale removal and water quality management.

4. Artificial intelligence device: adopts a timely water quality management system to manage water quality. The principle is to use intelligent management devices to continuously monitor the water quality of the water supply, dynamically adjust the working condition of the water treatment device, and ensure that the water quality meets the standards. At the same time, it automatically measures the water quality of the boiler water and automatically discharges pollutants based on the water quality of the boiler water. This method can reduce the influence of human factors, ensure the quality of boiler feedwater and boiler water meets the standards, and is currently the main means of intelligent water quality management in developed countries in Europe and America.
