Description
Technical field
A kind of water supply line for converting feedwater preheater, belongs to conversion boiler pipeline technology field.
Background technology
Feedwater preheater has two effects：First, the conversion process gas of desuperheat to 285 DEG C is further dropped to 155
DEG C to meet the requirement of conversion process；Second, the temperature of boiler feedwater is brought up to 200 DEG C from 105 DEG C by exchanging heat, its stove water
Major part is sent to artificial oil drum, is sent to conversion drum on a small quantity to meet the needs of device.It is normal to convert feedwater preheater
During operation, the higher shell side of pressure（Boiler water）Vessel flange weld seam produces crack, and boiler water, which largely leaks to directly affect, to be turned
Change and the normal production run of rear process, particularly influence the boiler water consumption of artificial oil drum, cause F.T catalyst temperature runaways.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can allow feedwater preheater shell side to keep low pressure fortune
Row, the conversion feedwater preheater water pipeline for meeting artificial oil dum boiler water consumption.
In order to solve the above technical problems, the technical solution adopted in the present invention：A kind of benefit for converting feedwater preheater
Water pipeline, including go artificial oil gas bag water supply line, go conversion drum water supply line, go cooling water head tank water supply line and benefit
Water bus；
The moisturizing bus, which supplies water, to be come from out-of-bounds, and is equipped with moisturizing main valve in moisturizing bus；
It is described to go artificial oil gas bag water supply line, go conversion drum water supply line, go to cooling water head tank water supply line one end equal
Connected with moisturizing bus, the other end connects artificial oil gas bag, conversion drum, cooling water head tank respectively, and is removing artificial oil
Gas bag water supply line, go conversion drum water supply line, go cooling water head tank water supply line to be respectively equipped with artificial oil gas bag valve
Door, remove conversion drum valve, remove cooling water head tank valve；
It is described to go conversion drum water supply line to be additionally provided with bypass valve, the moisturizing in conversion drum water supply line is gone through bypass valve
It is reverse to flow into conversion feedwater preheater.
Condensate flash barrel line is additionally provided between the conversion feedwater preheater and boiler water battery limit (BL) valve, and
Condensate flash groove valve is removed going condensate flash barrel line to be equipped with, it is described that conversion boiler feedwater is inversely flowed into through bypass valve
Preheater goes conversion drum water supply line moisturizing by going condensate flash barrel line to enter condensate flash groove.
Compared to the prior art the present invention has the advantages that：The newly-increased three times boiler water water supply lines of the present invention are kept
Convert feedwater preheater shell side low pressure operation, avoid causing at heat exchanger leak stopping leakage rate from increasing, be unable to maintain that production and
Parking.The normal moisturizing of artificial oil drum is also ensure that by increasing boiler water water supply line pipeline newly at the same time, it is ensured that F.T is catalyzed
The safety of agent.
Brief description of the drawings
Fig. 1 is the pipeline schematic diagram for converting feedwater preheater in the prior art.
Fig. 2 is the pipeline schematic diagram of the present invention.
In figure, 1 is goes artificial oil gas bag water supply line, and 2 is go conversion drum water supply line, and 3 be to remove cooling water head tank
Water supply line, 4 be moisturizing bus, and 5 be moisturizing main valve, and 6 is remove artificial oil gas bag valve, and 7 is remove conversion drum valve, and 8 be to go
Cooling water head tank valve, 9 be bypass valve, and 10 be conversion feedwater preheater, and 11 be boiler water battery limit (BL) valve, and 12 is cold to go
Lime set flash tank pipeline, 13 go conversion drum water supply line to remove condensate flash groove valve, 14 for original, and 15 remove artificial oil for original
Gas bag water supply line.
Embodiment
As shown in Figure 1, original goes conversion drum water supply line 14, original to go artificial oil gas bag water supply line 15 cannot be in conversion pot
Stove feed water preheater shell side pressure meets moisturizing requirement when larger, therefore designs three newly-increased water supply lines of the present invention.
As shown in Fig. 2, it is a kind of convert feedwater preheater water supply line, including go artificial oil gas bag water supply line 1,
Go conversion drum water supply line 2, go cooling water head tank water supply line 3 and moisturizing bus 4；
The moisturizing bus 4, which supplies water, to be come from out-of-bounds, and is equipped with moisturizing main valve 5 in moisturizing bus 4；
It is described to go artificial oil gas bag water supply line 1, go conversion drum water supply line 2, go to 3 one end of cooling water head tank water supply line
Connected with moisturizing bus 4, the other end connects artificial oil gas bag, conversion drum, cooling water head tank respectively, and is going to synthesize
Oil gas bag water supply line 1, go conversion drum water supply line 2, go cooling water head tank water supply line 3 to be respectively equipped with synthetic oil-air
Bag valve 6, remove conversion drum valve 7, remove cooling water head tank valve 8；
It is described to go conversion drum water supply line 2 to be additionally provided with bypass valve 9, the moisturizing in conversion drum water supply line 2 is gone through bypass
Valve 9 inversely flows into conversion feedwater preheater 10.
Condensate flash barrel is additionally provided between the conversion feedwater preheater 10 and boiler water battery limit (BL) valve 11
Line 12, and condensate flash groove valve 13 is removed going condensate flash barrel line 12 to be equipped with, it is described inversely to be flowed into through bypass valve 9
Conversion feedwater preheater 10 goes 2 moisturizing of conversion drum water supply line by going condensate flash barrel line 12 to enter condensation
Liquid flash tank.
It is described to go 2 moisturizing of conversion drum water supply line through the reverse inflow conversion feedwater preheater 10 of bypass valve 9
When returning to boiler water battery limit (BL) valve 11, boiler water battery limit (BL) valve 11 is closed, goes condensate flash groove valve 13 to open, remove conversion vapour
The moisturizing of bag water supply line 2 enters condensate flash groove, completes the waterway circulating of conversion 10 shell side of feedwater preheater.
Above-described embodiment is the explanation to structure of the present invention and unrestricted, is made without departing from the principles of the present invention
Deformation is also within protection scope of the present invention.
