Zastosowanie głębinowych agregatów pompowych w pompowni "Wola" KWK "Piast" (Komunikat)

W artykule przedstawiono w skrócie budowę i zasadę funkcjonowania Zbiornika Retencyjno-Dozującego "Wola". Uruchomienie i wdrożenie do eksploatacji pompowni "WOLA" z zabudowanymi głębinowymi agregatami pompowymi praktycznie zakończyło cały, oryginalny projekt ochrony środowiska rzeki Wisły. W wyniku jego realizacji stworzono warunki do utrzymania standardów ochrony środowiska rzeki Wisły w przekroju poniżej ujścia wody ze Zbiornika Retencyjno-Dozującego "Wola", tj. uzyskania wartości stężeń sumy chlorków i siarczanów poniżej 1 g/l w ciągu roku [3] oraz wyeliminowania dobowych wahań zasolenia w wodach powierzchniowych.

The article presents the structure and working principles of the "Wola" Storage-Proportioning Re-servoir pumping plant. The idea to use the hydrotechnical method to protect the Upper Vistula from the discharge of underground brine from "Piast" and "Ziemowit" mines was based on storing a part of the most saline waters from these mines in the "Wola" Storage-Proportioning Reservoir created on the basis of the liquidated "Czeczott" mine in the period of Iow water levels in rivers and its discharge to the river Gostynka and further to Vistula in the period of medium and high water levels to guarantee the maintenance of the total concentration of ions: Cl- i S04-2 within 1 g/l. The current operation of the "Wola" Storage-Proportioning Reservoir fully corroborates the initial assumptions and it should be stated that the fuli effect was achieved after the introduction of the "WOLA" pumping plant. Wi-thout the controlled operation of the pumping plant, controlled by the current water level in the Vistula river, the regulation of the total concentration of chlorides and sulfates within 1 g/l throughout the year would not be possible. Using HDM - ANDRITZ RITZ deep-well pumping engines played a key role in this process and is the most modern solution for deep-well pumps and engines implemented in Polish bituminous coal mining.

Tomographic measurement techniques : visualization of multiphase flows

A tomographic measurement technique is applied for visualization of the local void fraction in the two phase flow of air and water in the mixing chamber of a two-phase-nizzle. With this measurement technique a high spatial and temporal resolution can be achieved. The measured physical property is the electric conductivity of the water. The conductivity is measured with pairs of wires strained in the investigated cross section. The measurement values are proportional to ralative liquid fraction. With an algebraic reconstruction technique (ART) the field of the liquid fraction in the investigated cross-section in calculated from the measurement values. The quality of the reconstruction is increased by a-priori-knowledge.
