Vacuum degasser economy depends on the deaeration water heating. The smaller the water within the deaerator heating, the better the working condition of degassing is. But the water in the deaerator heating not only affect the condition of the economy, but also affect the quality of the degassing, more specifically, within the deaerator water heating, the greater the deaeration, the better the quality. Of vacuum degasser work put forward a requirement is to ensure that is in addition to the gas content of oxygen in water is not too big. For that matter, in the best heating water in a vacuum degasser is the guarantee is in addition to the minimum heating gas requires oxygen content in water. How to improve the efficiency of vacuum degasser also become people consider one of the problems.
In conventional gas cut, if appear in the process of drilling fluid is used in vacuum degasser, can avoid gas cut effect the performance of the drilling work, reduce the mud pump wear and high efficiency of mud pump water, reduce the time of repairing the pump and stop drilling processing. In underbalanced drilling operation, how to improve the efficiency of vacuum degasser? Existing degassing equipment "mud gas separator can clear away the free gas in the drilling fluid, and the invasion to swim away from the gas of the drilling fluid system in to clear it up. However in underbalanced drilling, drilling fluid is the most prone to gas cut. The effect of vacuum degasser is to remove this part of the free gas. On how to improve the efficiency of vacuum degasser, designers have made significant achievements, as conventional drilling operation and underbalanced drilling equipment and underbalanced drilling operation smoothly and effectively separate gas provides the guarantee. However, how to improve the efficiency of vacuum degasser becomes a hot topic of more people.
On how to improve the efficiency of vacuum degasser, here are four ways:
1. How to improve the efficiency of vacuum degasser from the system: in view of the hollow ball broken, can't form good water film, thus affecting the vacuum degasser depth in addition to the problem of carbon, overhaul in 2003 has all the hollow ball after screening the discharged to backfill, adding some new hollow ball. In addition, separate three cooler cooling water drainage line, respectively, into the raw water tank, eliminate the influence of hydrophobic not free.
2. How to improve the efficiency of vacuum degasser from process adjustment:
(1) To adjust the steam, water, ensure smooth hydrophobic. Secondary cooler cannot have water, otherwise the long-running secondary cooler will scale, affect the normal operation of vacuum degasser.
(2) Timing dredges secondary steam inlet cooler, drain and drainage line.
(3) About how to improve the efficiency of vacuum degasser, in view of the water temperature is too low, the shortage problem of steam and heat, contact the factory and the joint device, adjust the preheating water, improve water preheating temperature, ensure good carbon removal effect. Suggested that the next time will steam plus hot line maintenance bold, and add 2 set of steam nozzle.
(4) Maintain the normal level of vacuum degasser, prevent water phenomenon.
(5) If the vacuum degree significantly decline, deterioration of carbon removal effect is remarkable, may be caused by system leakage. At this moment, how to improve the efficiency of vacuum degasser? Should switch to the standby tower in time, as the water pressure test method to find the funneled to prevent the situation further.
By studying how to improve the efficiency of vacuum degasser, of vacuum degasser equipment structure, a series of improvement and optimization operation, vacuum degasser carbon removal effect has been increased significantly. The periodic output amount of fabricated water from cloudy bed increases, acid, alkali consumption and water consumption decrease, external drainage water less, has obvious economic and environmental benefits.
