Boiler system capable of intelligently storing blowdown data

Abstract

The invention provides an intelligent control boiler system. The system is characterized in that the system automatically controls a boiler according to steam quantity generated by the boiler and water quantity input into the boiler; the boiler is subjected to blowdown regularly; a steam dome further comprises a water quality analyzer used for measuring water quality in the steam dome; the water quality analyzer is in data connection with a monitoring diagnosis controller, so that the water quality analyzer conveniently receives measured data; the boiler is subjected to blowdown regularly; a central diagnosis monitor stores benchmark data, PH value J, blowdown time T and blowdown velocity V; the benchmark data is blowdown amount V * T meeting the requirement when the PH value of water in the steam dome is J; and the boiler further has the function of automatically correcting the benchmark data according to the PH data in the steam dome. The boiler further has the function of automatically correcting the benchmark data, the benchmark data is automatically corrected according to the detected water quality blowdown situation, and regulation accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the field of intelligent control boilers and belongs to the field of F22. Background technique [0002] When the steam boiler is in operation, the boiler water is concentrated as the steam is produced. When the salt concentration rises to a certain level, the pot water will produce bubbles, soda and water will rise together, and a large amount of water will be carried in the steam, which will cause a serious false water level and make the control of the furnace condition unstable. Therefore, the salt concentration of boiler water must be controlled to ensure steam quality and boiler operation safety. [0003] my country has national standards for the water quality of industrial boilers. For example, in GB1576-2001, for steam boilers with a pressure of 1.6-2.5Mpa and a superheater, it is stipulated that the dissolved solids concentration (TDS) of the boiler water shall not exceed 2500mg / L. Among them, the dissolved solids can ...

Problems solved by technology

For example, 201510601501X automatically discharges sewage according to the steam-water ratio of the boiler, but the existing sewage discharge method is to automatically open the sewage valve when a certain parameter reaches a certain level, and close the sewage valve when a certain parameter drops to a certain low limit

Although this intermittent automatic sewage discharge method is improved compared with manual timed sewage discharge, the salt content always fluctuates between high and low limits, and because of the hysteresis of data control, there is still a certain amount of excessive discharge or insufficient discharge, which is not the best. Excellent pollution control scheme
