Industrial boiler water quality online detection method

Abstract

The invention relates to an industrial boiler water quality online detection method. The invention belongs to the technical field of industrial boiler water quality detection. The industrial boiler water quality online detection method comprises the steps that: before pot water is collected, strong airflow is blown into the boiler, air flow is uniformly sprayed into the boiler water in a peripheral divergence manner through the air diffusion ring, the airflow speed is gradually increased according to regular time, pot water is changed from a static state to a dynamic state to form vortexes, all impurity elements in the boiler water are mutually mixed in continuous and increasingly violent dynamic flowing; and finally, homogeneous pot water is formed. According to the invention, a certain change and improvement are carried out on the basis of the existing boiler water sampling technology, and the accuracy of boiler water detection is improved by improving the homogenization integrity ofthe collected boiler water, so that the later water quality adjustment means is more accurate, the water quality of the boiler is more excellent, and meanwhile, the method has the characteristics ofshortening the cooling time and accelerating the cooling efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial boiler water quality detection, in particular to an online detection method for industrial boiler water quality. Background technique [0002] Industrial boilers are important thermal power equipment, widely used in various aspects such as factory power, building heating, and people's lives. The heat energy of fuel combustion is absorbed internally and converted into high-temperature water or water vapor, so as to realize heat energy transfer or power work. [0003] For the safe and energy-saving operation of industrial boilers, boiler water needs to be added to reduce corrosion and scaling, and the water inside the boiler needs to be frequently discharged to reduce impurity content; the national standard GB / T1576 "Industrial Boiler Water Quality" stipulates that qualified The industrial boiler water quality index, if the water quality does not meet the standard, the boiler will be in an unsaf...

Problems solved by technology

[0005] However, in the same boiler but at different depths and different locations, the types of impurity elements are also different. It is difficult to obtain uniform and comprehensive water samples in the boiler by relying on existing conventional samplers and sampling techniques to sample the water in the boiler. , therefore, the test results have certain inaccuracies, which can easily mislead the water quality adjustment methods (dosing or sewage discharge, etc.) in the later stage. Therefore, it is urgent to improve the boiler water sampling technology and improve the accuracy of boiler water quality testing.
