Desalination system production technology uses IDE companies of Israel low-temperature multiple-effect seawater desalination technology, installs 8 sets of sea water desalinating units altogether,
It is made up of per covering device 14 effect evaporators, it is 25000t/d that single Analysis of Nested Design, which is contributed,.5,6 sections of technology utilization steam turbine draws gas as dynamic
Power steam, evaporation seawater production fresh water, product water is in addition to as Power Plant make-up water, industrial water and domestic water, big portion
Divide and supplied to urban pipe network, strong brine caused by desalinization drains into the saltern closed on and is used for salt manufacturing and other byproducts.
In the process of running, performance is more good, does not occur large-scale phenomenon of the failure for sea water desalinating unit.But with
The growth of run time and the aging of equipment.Seawater desalination system occurs that sea water desalinating unit product water conductance is being run once in a while
During situation about increasing suddenly, eventually pass through and check that discovery has following reason to cause:
1st, because pipeline aging in long-term operation engineering, water impact ftractures in the presence of stress, causes pan feeding
Seawater leaks, and inversely enters from product water flash distillation pipeline in product water flash tank, causes contamination of products, conductance uprises.
2nd, shower inner nozzle causes nozzle to come off in long-term running, or crooked, causes water distribution uneven, enters
Expect that seawater inversely enters in product water flash tank from product tax flash distillation pipeline, cause product water light contamination, conductance uprises.
3rd, the light device effect body liquid level gauge failure in sea, imitate internal actual liquid level and show liquid level higher than monitoring card, high level is led
Causing seawater to enter by demister overflow in steam heat-exchanging tube bank causes product water conductance to raise.
4th, imitate internal heat-exchanging tube bundle and larger breakage occur, seawater enters during heat-exchanging tube bundle forms membranaceous flowing
Inside heat-exchanging tube bundle, product water conductance is caused to raise.
Low-temperature multi-effect seawater desalination device is only in final product exit of pump sampling and measuring electric conductivity value, such a measurement at present
Although mode can ensure the monitoring of product water conductance, product water conductance occur it is abnormal when can not effectively judge be
Which effect there is a problem.Under current running status can only after there is accident by overall stoppage in transit sea water desalinating unit,
The mode for opening manhole progress internal check confirms the reason for product water conductance raises and position.Because that can not judge what is gone wrong
Body is imitated, in checking process is overhauled, effect body inner case, work can only be checked by effect by way of fully open manhole checks
Measure extremely heavy.
