Abstract
A waste gas treatment system has a primary cooling section provided at a stage subsequent to a decomposition treatment section in which a waste gas is subjected to decomposition treatment at high temperature. The primary cooling section has a liquid spray part for spraying a liquid on the treated gas from the decomposition treatment section. A secondary cooling section cools the treated gas sprayed with the liquid in the primary cooling section to reduce the volume of the treated gas. Further, a particle collecting section injects a liquid into the treated gas cooled in the secondary cooling section to collect fine particles contained in the treated gas.
Claims28
A waste gas treatment method comprising:
- after a waste gas has been subjected to decomposition treatment at high temperature in a decomposition treatment section, spraying the treated gas subjected to the decomposition treatment with a liquid in a primary cooling section to cool the treated gas;
- cooling the treated gas in a secondary cooling section with a cooler cooled by a refrigerator to reduce a volume of the treated gas;
- and
- collecting fine particles contained in the treated gas in a particle collecting section.
A treatment system comprising:
- a primary cooling section provided at a stage subsequent to a decomposition treatment section in which a waste gas is subjected to decomposition treatment at high temperature, said primary cooling section having a liquid spray part operable to spray a liquid on the treated gas from the decomposition treatment section;
- a secondary cooling section having a cooler cooled by a refrigerator, said secondary cooling section being operable to cool the treated gas sprayed with the liquid in said primary cooling section to reduce a volume of the waste gas;
- and
- a particle collecting section operable to inject a liquid into the treated gas cooled in said secondary cooling section to collect fine particles contained in the treated gas.
A waste gas treatment system comprising a decomposition treatment section operable to subject a waste gas to decomposition treatment at high temperature, and a treatment system, said treatment system comprising:
