This utility model is possible not only to reduce the dismounting number of times of plate type heat exchanger, and can thoroughly clear up board-like changing
The problem of hot device coolant side dirt, effectively avoids the plate type heat exchanger dismounted frequently and cause simultaneously
The problem of leakage.Additionally, this utility model be also equipped with simple to operate, safe and reliable, time saving and energy saving, economical
The obvious effect of benefit.
Accompanying drawing explanation
Fig. 1 is the self-stripping unit structural representation of one embodiment of this utility model；
In figure: 1 flowing water Valve, 2 clean pumps, 3 clean water tanks, 4 enter penstock, 5 compression
Air interface, 6 plate type heat exchangers, 61 cooling water outlet pipes, 62 cooling water inlet pipes, 7 water tanks
Water injection valve, 8 detergent lines.
Detailed description of the invention
As it is shown in figure 1, the self-stripping unit of plate type heat exchanger that one embodiment of this utility model relates to is general
Property ground include: for depositing the cleaning water tank 3 cleaning plate type heat exchanger 6 cleanout fluid, for water tank will be cleaned
The cleanout fluid of 3 pumps into the cleaning pump 2 in plate type heat exchanger 6, and for carrying the detergent line 8 of cleaning,
This detergent line 8 connects cleans pump 2 and plate type heat exchanger 6, and it is clear to be provided with break-make in detergent line 8
Wash the control valve of pipeline 8, and for the plate type heat exchanger 8 after cleaning carries out purging the compressed air of operation
Interface 5.
The self-stripping unit of the present embodiment is independent outside the heat exchanging pipe being arranged on plate type heat exchanger 6, only exists
Plate type heat exchanger 6 needs just to put into operation when cleaning.Operationally, the Inlet and outlet water of plate type heat exchanger 6 is closed
Mouthful, start the circulation that self-stripping unit is constituted with plate type heat exchanger 6, by comprising the clear of specific cleansing medium
Washing liquid, washes away repeatedly to the inside of plate type heat exchanger 6, can be by the precipitation within plate type heat exchanger 6 and knot
Dirt cleans out.The present embodiment need not dismantle plate type heat exchanger 6, it is possible to keeps the sealing of plate type heat exchanger 6
Effect, reduces the workload of attendant simultaneously.
Further, in an embodiment of the present utility model, this control valve can include controlling cleanout fluid
Enter plate type heat exchanger 6 enters penstock 4, and the flowing water Valve of cleanout fluid discharged by control plate type heat exchanger 6
1.This cleaning water tank 3 can include that outlet and water inlet, outlet connect with the entrance cleaning pump 2,
The water tank with water valve 7 controlling to clean water tank 3 additional clean liquid it is provided with on water inlet.This detergent line 8 is pacified
Can connect with the cooling water outlet pipe 61 of plate type heat exchanger 6 in the one end taking on penstock 1, and clean pipe
Can connect with the cooling water inlet pipe 62 of plate type heat exchanger 6 in one end that road 8 is installed into penstock 4.Should
