Description
Technical field
The present invention relates to cooling circulating water system treatment agent multiple branch circuit auto-feeding device and methods outside a kind of valve.
Background technique
Converter station is each equipped with the outer cooling circulating water system of valve.The outer cooling circulating water system of valve is a special ecological ring
Border is suitable for the growth of multiple-microorganism.The mass propagation of microorganism can bring a series of harm to circulation, such as viscous
Mud deposition, line clogging, heat transfer efficiency reduction, equipment corrosion etc..In addition, circulation can also in system operation
Scale problems are generated, various deposits has been adhered on the tube wall surface that heating surface is contacted with cooling water, closed cooling tower will be made
Efficiency reduces, and operation and operation to cooling water system bring very big difficulty.
In order to avoid and mitigate deposit generation, prevent the reduction of heat transfer efficiency, extend closed cooling tower use the longevity
Life, it is necessary to prevent the generation of dirt and the growth of microorganism.For this purpose, current each converter station takes cooling circulating water system outside valve
Handling of Stabilizing Water Quality work, i.e., manually periodically add fungicide and corrosion inhibiting and descaling agent to circulation.Current dosing method
Are as follows: converter station operations staff pours into the medicament in explosive barrel in explosive box manually, then the dosing pump by being mounted on explosive box
By medicament from extracting out and be added into circulation in explosive box.
It is average when being run from western converter station normal full load according to statistical data by taking south electric network is from western converter station as an example
Need to be added within every two days 3 barrels of medicaments, every barrel of dose weight is 25kg, and 3 barrels of medicaments are 75kg.The artificial hand currently taken
Dynamic dosing method has the disadvantage that first is that needing two people to lift the explosive barrel for the 25kg that weighs and be more than drug storage case lid open height every time
It pours into again afterwards, very arduously, ergonomic is very low；Second is that will carry out within every two days the addition work of 3 barrels of medicaments, consumption is big
Amount personnel's energy and time；Third is that due to medicament have stronger corrosivity (corrosion inhibiting and descaling agent is prepared by sulfate etc.,
Its pH value less than 3), therefore must take safeguard procedures in 1% aqueous solution during adding, as wearing gloves, eyeshade and
Mask etc., if invading the medicament of while falling, pleasing to the eye or entrance need to see a doctor as early as possible accidentally, not only cause serious injury to the person, it is also possible to cause
Power equipment damage.
Summary of the invention
The inconvenience for the treatment of agent work is added for current manual, the present invention is provided at a kind of outer cooling circulating water system of valve
Medicament multiple branch circuit auto-feeding device and method are managed, selection respective branch can be judged automatically, add medicine automatically out of multiple explosive barrels
In agent to explosive box, human resources and time cost are saved, promotes ergonomic.
To achieve the above object, the technical scheme is that
A kind of outer cooling circulating water system treatment agent multiple branch circuit auto-feeding device of valve, including explosive box, into medicine hose,

Further, dosing pump, control cabinet and the solenoid valve is mounted on the small of stainless steel material for operating easily,
Che Shang is 170cm apart from ground level.
A kind of outer cooling circulating water system treatment agent multiple branch circuit of valve is automatically replenished method, is realized, is wrapped by above-mentioned apparatus
Include following steps:
Step 1, the low liquid level definite value and high liquid level definite value that explosive box is arranged in control cabinet, are arranged each stream in control cabinet
The liquid level definite value of each second liquid level sensor is arranged in the flow rate set value of meter in control cabinet；
Step 2, when control cabinet judges the low liquid level definite value of the liquid level of explosive box lower than setting, start dosing pump, and beat
The solenoid valve on first drug hose is opened, the medicine in corresponding first explosive barrel is added in explosive box；
Step 3, when the flowmeter on first drug hose measured discharge value be less than setting flow rate set value or first
When the actual measurement level value of the second liquid level sensor in a explosive barrel is less than the liquid level definite value of setting, the medicine in first explosive barrel is judged
Agent has exhausted；
If the high liquid level definite value of setting has not been reached yet in the liquid level of step 4, at this time explosive box, it is soft to close first drug
Solenoid valve on pipe opens the solenoid valve on second drug hose, and the medicine in second explosive barrel is pumped into explosive box；
Step 5 repeats step 3 and step 4, the solenoid valve on each drug hose is successively opened in order, successively by each medicine
Medicament in bucket is added in explosive box；
Step 6, when the liquid level of explosive box be more than setting high liquid level definite value when, control cabinet stop dosing pump operation, and
The solenoid valve on current drug hose is closed, when explosive box liquid level need to carry out dosing again below the low liquid level definite value of setting,
Control cabinet default restarts dosing from the current drug hose；
Step 7, when the last one flowmeter measured discharge value be less than setting flow rate set value or the last one second liquid
When the actual measurement level value of level sensor is less than the liquid level definite value of setting, the medicament being judged as in all barrels of medicines all exhausts, control
Case processed stops dosing pump operation and lights warning light, reminds personnel to replace explosive barrel, even if explosive box liquid level is reduced to low liquid at this time
Position definite value will not start dosing pump；
Step 8, when explosive barrel replacement after the completion of, manually control cabinet need to be resetted, recovering step 1 to step 7
Automatic function.
Further, the control cabinet also can switch to manual dosing mode, can be manual when switching to manual mode
Start dosing pump and solenoid valve carries out dosing, and when the liquid level of explosive box is more than the high liquid level definite value of setting, control cabinet stops
The operation of dosing pump.
Inconvenience of the present invention relative to artificial addition treatment agent work, has the advantage that
1, dosing pump is controlled by control cabinet and carries out being automatically replenished for medicament, avoid needs two people to praise every time weighs 25kg's
Explosive barrel, significant increase ergonomic.
2, more barrels of medicaments can be disposably replaced, the work frequency that will currently replace 3 barrels of medicaments for every two days is reduced, effectively saves
Human-saving resource and time cost.
3, prevent personnel praise in explosive barrel as medicament invade spill caused by personal injury and power equipment damage.
