To provide a system for cleaning a gas to be treated and depositing a catalyst by using a new hollow structure substitutable with a honeycomb structure.
The hollow structure for cleaning the gas to be treated and depositing the catalyst has a hollow body composed of ceramics or a heat-resistant metal as a part of a carrier or a filter part. The carrier or the filter part is composed of an aggregate of the hollow bodies each having the predetermined size and a through-hole is formed on the wall surface of the hollow body as a gas passage. The system for cleaning the gas to be treated and depositing the catalyst is characterized in that the hollow structure is arranged in the predetermined position in a vessel or a pipeline and each of both ends of the hollow structure is fixed immovably by a fixing means having apertures through which the gas to be treated passes satisfactorily. As a result, this system can cope with various unit shapes. The deposited catalyst does not drop out even when hollow bodies are rubbed against one another. The gas to be treated can be cleaned efficiently and a catalytic reaction can be advanced.
