This article briefly describes the current situation of the drainage system in iron and steel enterprises,and proposes two stormwater and sewage diversion engineering programs.Through the scheme comparison and analysis,the final implementation plan is determined.Through the analy-sis of the implementation of an enterprise's stormwater and sewage diversion project,the reasons why there is still a small amount of drainage in stormwater pipes on sunny days are clarified,and rel-evant recommendations for improvement are put forward.
In view of the phenomenon of water bubbling up from the top of the multi-media filter occurs when filtering the recycling water in the pre-treatment stage of the wa-ter desalination process of a desalination station of Beijing Shougang Co.,Ltd.,the top ex-haust valve,water cloth,filter material,backwash discharge pipeline,air source pneumatic valve,operation mode,operation method and other factors of the filter were analyzed,and the paper puts forward to adapt the stainless steel float,optimize the water distributor,re-place the filter media,backwash discharge pipeline dredging and other measures to solve the problem.
The article describes the supporting inverter over-temperature failure com-bined with the variable pressure adsorption oxygen production process,briefly explains the reason of heat generation inside the frequency converter through the case study,and puts forward the optimization plan for the poor circulation heat dissipation of the frequency con-verter cabinet and the problem of reactor heating,aiming at explaining that the optimization of frequency converter and the supporting equipment should be based on the actual process and working conditions at the site during the design,selection,and manufacture,so as to improve the stability of the frequency converter operation.
In the turbine system of a power plant,condenser vacuum will directly affect the reli-ability,safety,economy and stability of the unit,and the leakage of the vacuum system is the main cause of vacuum degradation.By means of helium mass spectrometry for a comprehensive inspection of the unit vacuum system and the application of a soft treatment process,the vacuum of the system can meet the standards of the electricity regulations and lead to a significant improvement in the economy of the generating unit.
The convective thermal resistance and fouling thermal resistance of the con-denser are the key factors affecting its heat transfer efficiency,and the condenser heat trans-fer efficiency directly affects the unit vacuum value.From the mechanism of condenser ther-mal resistance,this paper explores the reduction of condenser convective thermal resistance and fouling thermal resistance,so as to improve the condenser heat exchange efficiency.Studies have shown that changing the fluid pattern in the condenser tube can reduce the thermal resistance of the condenser.Adding RCCS device to alter the condenser fluid pat-tern can improve the thermal efficiency and power generation of the unit with significant economic benefits.
