By P-500 Centrifuge Ruifeng salt firm in the use and operation of method issues, combined with sensible encounter, a short introduction and improvement of irrigation strategies to accomplish economic advantages.
1 of the issue 2005 in the second half, our huge-scale Technologies Transformation, the new units on the two P 1 500 horizontal two-stage pusher Centrifuge . Simple operation of the centrifuge, processing capacity, around 15t per hour, salt production, wet salt water content material of about 2.5%, dehydration overall performance much much better than the original wH a 800 horizontal single-stage pusher centrifuge. The device is put into operation in early stage there had been some abnormal operating phenomena, such as drum stuck can not drive cars and influence the typical. Right after cautious analysis, an improved chassis washing procedure of the original program. Practice has proved that the enhanced operating outcome is good, because it has not noticed centrifuge drum card impact the production scenario of death.
two measures 2.1 drum stuck to recognize the reasons
Stuck for Centrifuge plate cars are not versatile phenomenon. After cautious research and discussion, the factors for excluding the mechanical and climatic motives, primarily the latter case there are product salt (fine grain salt and sodium), brought on by incomplete washing.
two. two create measures 2.2.1 prior to and right after the rinse water separate case when the initial installation, just before and soon after the case is linked to irrigation water, with a handle valve at the identical time just before and after the case flushing, shown in Figure 1.
This installation has the following drawbacks:
First, ahead of and right after the case connected to the inlet of the former cabinet thick, partial pressure, the resulting lack of water right after the wash cabinet
Second Whitewater slammed into by the former case, following a mixed answer of a brine evaporation tank barrel, soon after the case to ensure the flushing effect, to extend the wash time and increases the white water into the evaporation method of production is unfavorable. Soon after evaluation and discussion, proposed ahead of and following the casing procedure rinse water separate programs, every with two handle valves. Washing alone, shown in Figure 2.
2.2.two recoil after the separation following the case in view of the two can not guarantee 100% flexible to turning to an analysis that the case is nevertheless not completely clean the salt accumulation . In accordance with standard practices, to take the initial portion of the entire physique
Out, after the case can be cleaned of salt within the same time, dredge the flushing pipe at least 2? 3d. Standard irrigation pipeline flow shown in Figure three.
The difficulty from one more viewpoint, the water Department will be able to water, water Division will be capable to water, according to this idea, the following improvements, the original outlet pipe 3 recoil , 1,2 Department of the water, shown in Figure four.
Proved that the plan is feasible. By) the enhanced centrifuge manual Turning flexible.
three improved the price-effectiveness Technology 3 months to implement reform, centrifuges running in great condition. Prior to the transformation occurred numerous occasions simply because of centrifuge plate cars are not flexible and effect of production, therefore delaying the standard salt discharge phenomenon, the average delay per vehicle 2h, two instances a month to drive an hour Evaporation of power consumption 1 000kwh, to three month, .6 yuan / l electric meter. You can save electricity l OO0 2 2 3 .six = 7 2O0 dollars
The very same time. Turning to avert troubles when driving, parking for two hours when the general rinse to pump motor 22kW, main motor 45 l W total, 3 months to save electricity: (22 +45) two 3 three 2 .6 = 1450 2 Total direct savings: 720o +1450 = 8650 Wu
4 input and output ratio Rehabilitation aluminum tube about 15 common 15 m, gaze intently aluminum tube about l0m. Total investment: 15m 4 / m +10 m 5 / m = ll0 per input and output ratio: ll0/8650 = l/78.6
Drum stuck phenomenon happens more in winter, mostly the low temperature, nitrate easy to precipitation. By taking the class frequently brush truck (gear factory for various components have been relevant needs) and open the flush valve cavity right after flushing, found that poor ought to be instantly following the cavity backwash outlet, to stay away from the drum stuck phenomenon, to ensure smooth production.
