Online industrial boiler water vapor quality detection system

Abstract

The invention relates to an online industrial boiler water vapor quality detection system, which comprises a sampler, a sensor and a processor, wherein the sampler comprises an outer cylinder, a boiler water sampling inner cylinder, a feed water sampling inner cylinder and a partitioning plate; both the boiler water sampling inner cylinder and the feed water sampling inner cylinder are both arranged in the outer cylinder, and a hollow interlayer for filling cooling water is formed with the inner wall of the outer cylinder; the boiler water sampling inner cylinder is internally provided with afirst conductivity sensor and a pH value sensor; the feed water sampling inner cylinder is internally provided with a second conductivity sensor; and the processor is connected with the first conductivity sensor, the pH value sensor and the second conductivity sensor respectively. Through online and real-time continuous detection, the industrial boiler water quality condition can be timely fed back, the workload of a worker is reduced, a boiler operator is timely guided for correct operation, and boiler fouling and energy waste are reduced to the maximum degree.

Description

technical field [0001] The invention relates to the field of industrial boilers, relates to the laboratory analysis of water vapor quality of industrial boilers, and in particular to an on-line detection system of water vapor quality of industrial boilers. Background technique [0002] According to the requirements of Article 21 of TSGG5001-2010 "Boiler Water (Medium) Quality Supervision and Management Rules", boiler users should conduct routine laboratory analysis of water vapor quality on a regular basis. At present, the usual method for water quality testing of industrial boilers is that the laboratory personnel use containers to hold the boiler water cooled by the boiler water sampler. The conventional sampler is installed in the boiler room as a non-pressure-bearing part of the boiler. Each boiler needs to be equipped with a boiler water sampler. The boiler is generally installed next to the boiler, and it only has the function of cooling the boiler water. Iron products...

AI Technical Summary

Problems solved by technology

Boiler water and feed water have to be sampled separately, labor-intensive, and samples are taken at different time periods, the data of laboratory analysis fluctuates greatly, the laboratory data has a large lag, and it is more dependent on the consciousness of laboratory personnel, many industrial boilers are not equipped with full-time Laboratory personnel cannot perform tests according to the time specified in the standard, cannot guide the boiler operators to perform correct operations at the first time, and cannot reasonably carry out sewage discharge or dosing work, which leads to easy fouling of the boiler or excessive sewage discharge
