Steam condensate (SC) slot 12 is connected to condensate draining.
Explanation as further unnecessary auxiliary:
1, after operations staff is by opening sump pump to each manually operated door of ammonia vessel, starting sump pump is to ammonia vessel moisturizing (note
Waste water in storage tank should be put into time when meaning melt pit liquid level bottom, while noticing that ammonia vessel liquid level is no more than 1m), operator can lead to
It crosses and adjusts one, two, three aperture regulation moisturizing speed.By melt pit pump shutdown after ammonia vessel liquid level is up to standard, moisturizing is closed with respectively
Manually operated door opens reflux door, and waste water in pipeline is drained back to melt pit (winter pipeline is avoided to freeze).
2, after ammonia vessel liquid level is up to standard, each equipment inlet and outlet manually operated door is opened in inspection system, and sewage door is closed, oil strain portion
Dividing wouldn't put into operation, and each Thermal Meter comes into operation normally, while checking intact each favourable turn mechanical part, lubricating oil and cooling water system just
Often, the normal rear power transmission of insulation is electrically shaken in connection.
3, starting aqua ammonia pump is to system pipeline filling liquid, when room liquid level to be evaporated is to 1.2m, starts circulating pump to big heater
And boiler pipe water-filling, it keeps vaporization chamber liquid level in 0.5m or so by adjusting circulating pump inlet and outlet manually operated door, is filled to system
After full water (only risen by vaporization chamber liquidometer and do not drop judgement), stoppage in transit aqua ammonia pump, circulating pump remains in operation, and whether there is or not let out for inspection system
Leak source.
4, check that vaporization chamber emptying door is opened, manually operated door is closed at flue.After all going well, the steam that puts into operation heating system
System, is separately turned on the inlet valve and draining valve of vaporization chamber, big heater, boiling device, controls and heats by adjusting inlet valve aperture
Speed (loseing steam with steam condensate (SC) slot emptying door is advisable).When pump discharge temperature to be recycled is up to 50 DEG C, oil strain part of putting into operation,
Oil filter import manually operated door and ammonia vessel import manually operated door (paying attention to ammonia vessel liquid level, prevent exhausted water overflow) are opened, according to feelings
Condition starts aqua ammonia pump, keeps each liquidometer in normal range (NR).
5, emptying door is closed when vaporization chamber emptying door steams larger, while opening manually operated door at flue.It is to be recycled to pump out
When mouthful temperature is up to 70 DEG C -80 DEG C, wastewater trough intake gate (paying attention to wastewater trough liquid level, prevent exhausted water overflow) is opened, boiler is contacted
Operator on duty opens 8 meters of boiler places and burns spray gun import manually operated door, starts waste water pump and turns waste liquid at 8 meters of boiler, spray gun is shown in
Burner hearth is pushed it into after liquid, passes through flame television monitoring spray gun operating condition.
6, operations staff can make a liquidometer in system be in a kind of dynamic equilibrium by adjusting each sink intake gate aperture
State, should be in time by sump pump to ammonia vessel fluid infusion in operation.In the insufficient situation of melt pit liquid level, wastewater trough water inlet can be closed
Burning spray gun is pulled out and closes intake gate by door, stoppage in transit waste water pump.Make waste liquid circulating and evaporating in system.Operations staff answers
It is primary that oil filter bottoms tar was put every 24 hours, and tar in oil drum is delivered to fuel reserve tank by tar pump.
7, system shutdown should first exit each heating device vapour side, close into porthole, recycle in system 20 minutes to liquid
Drain water piping wicket is opened afterwards, and discharge line internal water accumulation (avoids winter frost crack pipe), pumps by steam condensate (SC) by steam
Condensed water trough inner water is stopped transport after emptying, and is turned evaporation indoor liquid to wastewater trough by circulating pump and is passed through waste water pump for raffinate
Body is transmitted back to after melt pit each pump of stopping transport.Winter answers shutdown system that waste liquid in pipeline should be discharged the bottom of by time, avoids pipeline
Bursting by freezing.
As a further preference, power generation is recycled to ground by bottom discharge pipe with coke oven tail gas conveyance conduit gas condensed water
In hole and storage tank, it is connected between melt pit and storage tank by pipeline.
In a creative way, above each effect is individually present, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technical effect that the above structure is realized is realized, if the additional technical solution is not taken into account, this patent title is also
It can be a kind of new type purification system.Part details is not shown in the figure.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
Basic principles, main features, and advantages of the present invention has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen in claimed range.
