TECHNICAL FIELD
[0001] The utility model relates to industrial furnace water water quality processing technical field, concretely is a kind of for furnace water phosphate ion's adjusting device. BACKGROUND
[0002] In many industrial production scenes, for example, power plant, chemical plant, steel plant etc., boiler as the key heat supply equipment plays a very important role. Steam pocket is an important device in boiler equipment, and is the connecting hinge of the three processes of boiler heating, vaporization and superheating. The water quality of furnace water in the steam pocket is directly related to the operation effect, service life and safety of the boiler and many other aspects. Among them, the phosphate ion concentration is one of the key indicators of measuring the water quality of furnace.
[0003] At present, for the adjustment of the phosphate ion concentration of furnace water, the artificial operation mode is mainly adopted. However, this artificial adjustment mode has a series of obvious disadvantages. First, in the monitoring link, artificial detection of phosphate ion concentration cannot realize real-time, continuous and accurate measurement. Usually, artificial sampling is carried out periodically, and then the sample is sent to the laboratory for analysis and detection. In this way, it is difficult to capture the dynamic change of the phosphate ion concentration of furnace water in time, resulting in obvious lag of the adjustment action, and the rapid fluctuation of the water quality of furnace in a short time cannot be effectively responded. Second, as for the adjustment operation, the artificial measurement accuracy has great limitations. Since the steam pocket is large in volume, the phosphate ions in the furnace water in the steam pocket are stratified, and the concentration of phosphate ions at different positions is different. The artificial sampling points are limited, and the overall concentration of the steam pocket cannot be accurately reflected, so it is difficult to accurately and stably maintain the phosphate ion concentration in the ideal range. Once the phosphate ion concentration deviates from the appropriate range, it is easy to cause the scaling, corrosion and other adverse phenomena of furnace water, which will seriously affect the heat transfer efficiency of the boiler, shorten its service life, and may cause equipment failure, threatening the normal operation of the whole production process.
