Boiler system with intelligent control of blowdown time by cloud computing

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 speed is kept invariable; a central diagnosis monitor automatically sets a pollution discharge time according to the measured PH value to automatically control the pollution discharge quantity; the monitoring diagnosis controller is in data connection with a cloud server for transferring monitored data to the cloud server; the cloud server is connected with a client; and the client can obtain the monitored data through the cloud server. Through real-time monitoring of the PH data of each boiler, the pollution discharge time is automatically adjusted according to a dynamic proportional relation; the 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...

However, the on-site conditions of the system are complex and changeable. When the operation plan obtained by the local server cannot meet the needs of the on-site situation, maintenance personnel need to arrive at the site to update the control program and parameters of the local server so that the local server can obtain an operation plan that meets the on-site conditions. Flexibly adjust the control program and parameters in the local server
