High-temperature condensation water fine treatment system and high-temperature condensation water fine treatment method

Abstract

The present invention relates to a high-temperature condensation water fine treatment system and a high-temperature condensation water fine treatment method. According to the present invention, through online detection, condensation water meeting the treatment standard is introduced into the treatment system, and the condensation water is subjected to deoiling, desalination and degassing through a ceramic membrane filter, a fiber pot and a vacuum oxygen removing device; in the case of no requirement of cooling, trace grease, iron ions, copper ions, SiO2 sol and other impurities in the high-temperature condensation water are removed; the repeatable unit can be according to the water inlet of the boiler water, and the repeating units are connected in series in the treatment system; the degassed purified water can be directly reused in the boiler water; and the high-temperature condensation water treatment does not require the heat exchange equipment and the ion exchange resin, and the water outlet effect of the boiler water can be achieved by using the ceramic membrane filter and the active carbon fibers as the purification main body unit so as to save the equipment investment cost and the material replacement cost during the operation.

Description

technical field [0001] The invention relates to a water treatment system and method, in particular to a fine treatment system for high-temperature condensed water that does not require heat exchange equipment, uses ceramic membrane filters and activated carbon fibers as the main unit for purification, and the purified water can reach the high-temperature condensed water required by the boiler water inlet and methods. Background technique [0002] At present, in petroleum, metallurgy, papermaking, chemical industry, food and other fields, steam is often used as the heat source, and the heat energy contained in the condensed water generated after steam condensation accounts for 10% to 30% of the total steam heat energy. Condensed water itself is relatively clean, but due to pipeline corrosion, process, equipment operation, material leakage and other reasons, it contains trace amounts of oil, iron ions, copper ions, SiO 2 Pollutants such as sol and soluble organic matter are g...

Problems solved by technology

In this method, the use of activated carbon fibers has wide applicability, but the treatment system is too rough

Due to the serious pollution of some condensed water, it is not suitable to directly enter the treatment section. This part of condensed water is introduced into the treatment system, which increases the processing load, and if the airtightness of the instrument is poor, a large amount of oxygen will be introduced, which does not meet the requirements for boiler water. water quality requirements

Patent CN1837104A provides a fine treatment system for fine treatment of condensed water. The system performs online detection, but the process is cumbersome and manual maintenance is difficult
