    • A pressure filtration system for cleaning residual quenching water of a gasifying device that gasifies carbon-containing fuels under elevated pressure is provided. The soot water from the quencher is passed to a filter system, which has pressure filter chambers operating alternately in filtering mode under gasifying pressure or in cleaning mode. The filtrate from these chambers is passed to a quenching water reservoir, from which the quencher is fed with quenching water. Only small temperature and pressure losses with respect to the residual quenching water leaving, and only a small additional amount of energy has to be expended to overcome the remaining pressure difference to bring the filtrate that is to be returned back to the gasifying pressure. The residual quenching water is cleaned substantially under gasifying pressure in a pressure filter, avoids flash evaporation of the residual quenching water into the vacuum area, with vapour cooling and a subsequent increase in pressure and reheating.
    • 提供一种用于清洁在高压下使含碳燃料气化的气化装置的残余淬火水的压力过滤系统。 来自猝灭剂的烟灰水被传递到过滤系统,其具有在气化压力或清洁模式下以过滤模式交替操作的压力过滤器室。 将来自这些室的滤液送入骤冷水储存器,淬火器从其中加入骤冷水。 相对于剩余的骤冷水而言,相对于残留的骤冷水只有较小的温度和压力损失,并且只需要少量的能量来消除剩余的压力差,以使待返回到气化压力的滤液。 残余淬火水在压力过滤器中基本上在气化压力下进行清洗,避免了蒸汽冷却和随后的压力升高和再加热使剩余的骤冷水快速蒸发到真空区域。
