The water quality problem of the steam boiler can be treated by softening water equipment and reverse osmosis equipment.
The demineralized water equipment mainly passes the raw water containing hardness ions through the resin layer through the ion exchange process, so that the calcium and magnesium ions in the water are replaced by the sodium ions in the resin, so as to remove the hardness ions and produce demineralized water. This equipment can be used for process water, cooling and replenishment water, boilers, etc., and can also be used in the steel smelting industry, chemical and pharmaceutical industry, etc. The softened water equipment can be automatically regenerated at regular intervals and constant flow, and the system adopts computer monitoring to realize continuous operation and fully automatic operation of the regeneration process.
Reverse osmosis equipment is a process that uses reverse osmosis membrane, which is composed of three parts: pretreatment system, reverse osmosis system and post-treatment. Reverse osmosis equipment can not only soften the raw water, but also have a high retention and removal effect on organic matter, colloids, particles, bacteria, viruses, heat sources, etc.
The combustion water of the steam generator furnace body needs to be treated by the RO reverse osmosis water purifier. The steam generator furnace body is different from the traditional boiler, and the integrated manufacturing process is adopted, and the water capacity of the furnace itself is small, so the poor water quality will lead to scaling problems and cause serious harm to the furnace body.
1. The existence of scale will lead to metal deformation and burning, because the thicker the scale, the lower the thermal conductivity, which will easily cause the problem of metal burning.
2. The existence of scale will increase energy consumption and deteriorate thermal conductivity, resulting in a large amount of heat being taken away by the flue gas, resulting in high exhaust gas temperature, thereby reducing the thermal power of the steam generator.
3. The presence of scale will shorten the service life of the steam generator, because the scale will continue to spread to the depths of the metal wall, resulting in metal corrosion problems, thereby shortening the life of the equipment.
The selection of RO reverse osmosis water purifier determines the water output per hour, which is generally several tons. In order to meet this water production, the amount of raw water that needs to be prepared should be twice the tonnage of the selection. The wastewater rate is usually 50%. If the conductivity of the raw water is low, the wastewater rate will be correspondingly lower;If the conductivity of the raw water is high, the wastewater rate will be correspondingly high.
For steam boiler water quality problems, whether to use softening equipment or reverse osmosis equipment should be determined on a case-by-case basis.
