A Steam Boiler System with Intelligent Control of Blowdown Base Data

Abstract

The invention provides a boiler system. The system performs automatic control according to the steam amount generated by a boiler and the input water amount of the boiler, and contamination dischargeis performed on the boiler regularly; a steam pocket further comprises a water quality analyzer to measure the water quality inside the steam pocket, and the water quality analyzer and a monitoring diagnosis controller are in data connection so that measured data can be received; the boiler further has the function of automatically correcting reference data according to the water quality inside the measured steam pocket, and the contamination discharge amount is automatically controlled according to the measured data. The boiler automatically calculates the the discharge capacity of the boilerso that the contamination discharge time and speed can be adjusted according to the contamination discharge amount.

Description

technical field [0001] The invention belongs to the field of steam 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 water in the pot will foam, and steam and water will rise together, a large amount of water will be carried in the steam, and a serious false water level will be caused, making 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 superheaters, it is stipulated that the dissolved solids concentration (TDS) of the boiler water shall not exceed 2500mg / L. Among them, the dissolved solids can be approximated a...

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
