Title:
VACUUM SEWARAGE SYSTEM AND VACUUM SYSTEM COMBINING DEVICE USED FOR THE VACUUM SEWARAGE SYSTEM
Document Type and Number:
Japanese Patent JP3270961
Kind Code:
B2
Abstract:
PURPOSE: To install a vacuum sewarage, independently of the size and level difference of an installation area and the presence of rivers.
CONSTITUTION: A sewarage pipe passage is divided into heads corresponding to vaccum pressure on water collecting tanks 11 to set unit pipe passages 3 and the ends on the upstream and downstream sides of the unit pipe passage 3 are connected to the water collecting tacks 11. All water collecting tanks 11 are connected to a vacuum pump via vacuum pipes 5. All water collecting tanks 11 are subjected to almost the same vacuum pressure and all unit pipe passages 3 connected to the water collecting tanks at the ends on the downstream side have almost the same water collecting ability, so that the vaccum sewarage is applicable in a wide range. A combining device C has the water collecting tanks 11 is which reservoirs 14 are provided for dirty water. When the dirty water gets to a preset level, vacuum pressure on the reservoirs is cut off and atmospheric pressure is guided thereto to outflow the reserved dirty water to the pipe passages 3 on the downstream side.
