Add the chemicals dosing plant of oxygen scavenger.
Background technology
High-temperature-hot-water generally refers to the Closed Cycle water system that supply water temperature reaches more than 80 DEG C, is widely used in living
Heat supply, in production technology, some production technologies can reach more than 150 DEG C, such as the painting entrucking in automobile production with the temperature of water
Between casting hot water etc..And just because of water temperature is especially high, in general corrosion inhibiter, which is difficult to veritably play, suppresses pipeline equipment corrosion
Effect.Therefore, by adding oxygen scavenger, after the oxygen in system is reduced into sufficiently low (0.1 even below 0.05mg/L) so that
The oxidizing reaction rate of metal significantly declines, so as to serve the effect for suppressing corrosion.
Existing oxygen scavenger dosing method typically has two kinds.First, artificial periodically sampling, molten using titration or laboratory
Oxygen instrument is detected, and finds Excessive Dissolved Oxygen or on the rise, then calculates oxygen scavenger dosage, and the scene of return manually add
Medicine, such a mode seem especially cumbersome, and manpower consumption is big, dosing hysteresis, are often had been subjected to from being sampled to supplement and adding oxygen scavenger
Even more than 1 day half a day, deoxygenation not in time, in order to ensure deaerating effect, it has to add oxygen scavenger overdose, medicament into
This rise；After water sample leaves the enclosed environment of system simultaneously, prohibited data detection will necessarily be caused true, differed with atmosphere
Surely truly reflect actual dissolved oxygen situation in high-temperature-hot-water.
Although another way is provided with online dissolved oxygen detecting system, but be only that one is opened on system manifold
Thief hole, and take over and draw to get off, sample cock is in normally open, implements continuous detection, and such a mode will cause system continuous
Dehydration is, it is necessary to continuous moisturizing, while extraneous oxygen is also constantly as system is brought in moisturizing into.And the water sample that such a mode is drawn
Not through supercooling, temperature is high, the temperature range that often can bear beyond dissolved oxygen meter.Even if it is mounted with sampling cooling dress
Put, then cooling water (such as running water) also must be normally opened, then cooling water consumption is just very big.
Therefore, it is necessary to develop a kind of oxygen scavenger chemicals dosing plant, high-temperature-hot-water oxygen dissolving value, timely automated supplement can be detected in time
Oxygen scavenger, hysteresis, excessive dosing are avoided, while artificial dosing workload can be mitigated, and avoid excessive extraneous dissolved oxygen with moisturizing
Bring system into.
