6c, level Four water inlet pipe 6d) it is divided into four branch roads, every the most corresponding one stage impeller 15 of branch road, provide distilled water for impeller 15
Wash ash disposal dirt fouling.
In Article 1 cleans bye-pass, one-level water inlet pipe 6a connects one-level manifold inlet valve 7a and first order jet nozzle 8a.
In order to control to enter the hydraulic pressure size of the distilled water of nozzle, connect the one-level water inlet of one-level manifold inlet valve 7a and first order jet nozzle 8a
Connect with arm on arm 6a and have one stage impeller inlet pressure gauge 9a, for display from one-level manifold inlet valve 7a distillation out
The force value of water.
Distilled water is ejected on one stage impeller 15a by first order jet nozzle 8a.First order jet nozzle 8a makes by one-level manifold inlet
Distilled water after valve 7a regulation supercharging forms atomization, thus water smoke and air are mixed on the one stage impeller 15 of high-speed cruising,
Reach to clean the purpose of dust.The structure of nozzle 8 will combine Fig. 2 later and be described in detail.
The sewage of cleaned one stage impeller 15a enters one-level water cooler 16a the most afterwards from one stage impeller 15a, and passes through
Primary effluent arm 10a flows out.In order to avoid entering one-level gas-liquid separator 11a from one-level water cooler 16a sewage out,
Thus affecting the work of one-level gas-liquid separator 11a, one-level gas-liquid separator 11a is respectively arranged at two ends with one-level gas-liquid separator
Entrance hands valve 12a and one-level gas-liquid separator outlet hands valve 13a, carries out closing one-level gas-liquid separator entrance hands when impeller cleans
Valve 12a and one-level gas-liquid separator outlet hands valve 13a.Additionally, one-level gas-liquid separator 11a, one-level gas-liquid separator entrance hands
It is parallel with one-level bypass valve 14a, from one-level water cooler 16a by the pipeline of valve 12a and one-level gas-liquid separator outlet hands valve 13a
Sewage out is discharged by one-level bypass valve 14a.
Clean in bye-pass at its excess-three bar, water inlet pipe 6, manifold inlet valve 7, nozzle 8, impeller eye Pressure gauge 9, go out
Water arm 10, gas-liquid separator entrance hands valve 12, gas-liquid separator outlet hands valve 13, the annexation of bypass valve 14 and Article 1
In branch road identical, repeat no more.
Please gather refering to Fig. 3 A, 3B and 3C, it is the structural representation of nozzle 8.Nozzle 8 is that the water after making supercharging forms mist
Change, thus and air be mixed into the impeller of high-speed cruising and reach to clean the element of the purpose of dust.Nozzle 8 has three portions
Point, small-bore section of the bore D1 of least significant end with the heavy caliber section of the bore D2 of the joining distal ends of water inlet pipe 6, be connected osculum
Footpath section and the changeover portion of heavy caliber section.Water enters nozzle 8 from heavy caliber section, is ejected to impeller from small-bore section.At preferred version
In, the bore D1 of small-bore section is 10mm, length L1 is 25mm, and the bore D2 of heavy caliber section is 25mm, length L2 is 25mm, mistake
The angle α that inside contracts of the section of crossing is 30 °.
Below by the operation principle of centrifugal compressor impeller fouling online treatment device of the present utility model and step
Illustrate.
Use the centrifugal compressor impeller fouling online treatment device of the present utility model impeller to centrifugal compressor
During cleaning, should be first from the beginning of the impeller of multi-stage impeller.In other words, centrifugal compressor to be cleaned has N level leaf
Wheel, then first start to clean from N level impeller, and N-1 level impeller is cleaned after cleaning by N level impeller again, and so on, finally to one
Level impeller is carried out.Detailed process is as follows:
(1) before the impeller being centrifuged formula compressor cleans, first water tank 1 topping-up, open inlet valve 3, open
Dynamic pump 4 runs, and can compare the reading of pump discharge pressure table 5 to regulate the outlet pressure of pump 4.
(2) N level impeller is cleaned: in order to prevent dust impurity from blocking N level gas-liquid separator 11, first temporary close N level gas-liquid
N level gas-liquid separator entrance hands the valve 12 and N level gas-liquid separator outlet hands valve 13 at separator 11 two ends, opens N level bypass valve
14；When the reading of regulation pump discharge pressure table 5 is to certain numerical value (if level Four impeller is 0.96MPa), open N level manifold inlet valve
7, the reading of N level impeller eye Pressure gauge 9 is regulated to higher than N level impeller 15 inlet pressure 0.35MPa, water smoke is from N level nozzle 8
Middle ejection is rinsed plot to N level impeller 15, removes fouling；Enter previous after the water discharged from N level bypass valve 14 is clean
The cleaning of level (N-1 level).
(3) clean N-1 level impeller: cleaning process is identical with N level impeller, differ only in regulation pump discharge pressure table 5
The numerical value (if three grades of impellers are to 0.82MPa, sencond stage impeller is 0.53MPa, and one stage impeller is 0.36MPa) of reading.
(4), after cleaning completes, recover gas-liquid separator 11 and use, open gas-liquid separator entrance hands valve 12, gas-liquid
Separator outlet hands valve 13, cuts out bypass valve 14, and pump 5 is out of service.
It should be noted that when every grade of impeller cleans, it is necessary to pressure when following flushing rinses level impeller higher than it and enters
Mouth pressure 0.35MPa.
In sum, centrifugal compressor impeller fouling online treatment device of the present utility model at least has following excellent
Point: in the case of (1) need not stop centrifugal compressor operation, online treatment runner, blade, Scale of blade problem；(2) profit
Being rinsed impeller with distilled water water smoke, developing result is good；(3) sewage after rinsing is discharged by bypass valve, not to centrifugal
In formula compressor, element impacts.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area
For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
