Technology Of Automatic Steam Boiler Water Treatment In High Conductivity Water Supply Region

According to the principles of sustainable development strategies, the need of clean manufacturing and clean production, boiler wastewater pollution prevention and control should be transferred from terminal control to process control. The basic concept of steam boiler zero flow consisted of "First, in order to reduce wastewater from ion exchanger, to remove this kind of water equipment or reduce the number of it; second, dosing scale inhibitor to prevent scale depositing and dosing high efficient corrosion inhibitor or oxygen-removal agent to decrease corrosion rate." In this article, technology of automatic steam boiler water treatment was introduced in high conductivity water supply region. Combined with outer heating oxygen-removal, reverse osmosis water treatment unit replace the ion exchanger to demineralize boiler supply water .It can decrease the flow rate of boiler. Inner dosing oxygen-removal agent and alkali-agent is additional treatment method to control pH value and conductivity.This thesis includes HKLE3600G style steam boiler water treatment method; study of feasibility of reverse osmosis (RO) membrane demineralized water process design and economical analysis; engineering case of RO membrane unit used in middle style steam boiler water treatment; dissolved oxygen removal; study of steam boiler water treatment agent EQ3F-N , it has some functions including, corrosion inhibition, dissolved oxygen removal, pH value maintenance, and so on.Through series of research and engineering practice, we draw a conclusion that RO membrane treatment technology and the multifunction agent can decrease the flow rate and save energy sources. To sum up, in high conductivity water supply region, for steam boiler, RO membrane unit is benefit for environmental protection. Using RO membrane treatment technology and the multifunction agent can lengthen steam boiler's life, raise its security and reduce running cost.
