Title: Gas cleaning filter unit and its manufacturing method
Inventor: OYASHIKI YASUSHI
IPC: B01D46/24
Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a high performance gas cleaning filter unit without impurity contamination as even a purification material, such as cleaned activated carbon, is insufficient for highly accurate purification caused by being contaminated during storage or by a storage container.  <P>SOLUTION: In a manufacturing method of the gas cleaning filter unit, after a heat-resistant closed type gas cleaning filter unit containing a physically adsorptive gas purification material is assembled, while the inside of the filter unit is scavenged with an inert gas or in a state connecting it to a low pressure source, the whole of the filter unit is heated so that high-temperature heating treatment is carried out until achieving the prescribed cleanliness. Subsequently, the gas inlet-outlet of the filter unit is sealed, thereby the cleanliness of a part contacting with a gas to be purified of the filter unit and the cleanliness of the purification material are collectively increased.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To reduce the chlorine concentration in a thermal decomposition residue in an apparatus for washing the thermal decomposition residue of waste which can separate the waste to thermal decomposition gas and the thermal decomposition residue and is suited for washing the separated thermal decomposition residue.  <P>SOLUTION: The waste is thermally decomposed in a thermal decomposition furnace 2, and the continuously produced thermal decomposition residue (carbide) is water-cooled and mixed with water in a cooling/mixing tank 6 to produce a carbide slurry. Chlorine included in the carbide is removed in the water of the carbide slurry. The carbide slurry is guided to a dewatering/washing apparatus 30 and is dewatered. In addition, the dewatered carbide is washed in the dewatering/washing apparatus 30. By the washing, the chlorine attached to the carbide is removed, and therefore the chlorine concentration in the carbide is further lowered. A water treating apparatus 31 performs desalination for the water dewatered by the dewatering/washing apparatus 30. Desalted water obtained by the desalination is reused in the cooling/mixing tank 6 and the dewatering/washing apparatus 30.  <P>COPYRIGHT: (C)2004,JPO
