Abstract

The invention provides an automatic control boiler system. The system comprises a monitoring diagnosis controller and a boiler; a steam drum comprises a water quality analyzer; the water quality analyzer comprises a PH value testing unit for measuring the PH value of water in the steam drum; the water quality analyzer is in data connection with the monitoring diagnosis controller to receive measured PH data; the boiler termly discharges pollutions; the pollution discharge time is kept invariable; and a central diagnosis monitor automatically sets a pollution discharge speed according to the measured PH value to automatically control the pollution discharge quantity. Through real-time monitoring of the PH data of each boiler, the pollution discharge quantity of the boiler is automatically calculated according to a dynamic proportional relation; the pollution discharge speed and the pollution discharge time are adjusted according to the pollution discharge quantity; a client can timely master the operation conditions of a boiler pollution discharge system; and pollution discharge parameters are adjusted timely through the client to prevent a lot of heat energy wastes caused by faults of the boiler pollution discharge system.

Description

technical field

[0001] The invention belongs to the field of 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 be approximated as t...
