Sealed shower system for rotary vacuum filter |
摘要 |
A sealed shower system applies shower water to a pulp mat as it passes through a sealed chamber under a vacuum with an air supply that is externally regulated. The shower water forms a pond or film on the pulp mat. The amount of entrapped air is minimized through a downleg of a filter drum which results in maximum filtrate flow, an increased drainage rate, higher efficiency washing and a requirement for less shower water per pound of pulp. In addition, with less entrapped air in the filtrate, the length of the downleg can be reduced enabling lower building heights, smaller filtrate tanks and foam handling systems. The sealed shower system also forms part of a combined shower/hood structure that greatly reduces exhaust emissions.
