Patent ID: 7537628

Claim:
An exhaust trap device for trapping solidified substances from an exhaust gas passing through a gas exhaust route, comprising: a plurality of exhaust trap sections arranged in series along the exhaust route, each section having an internally formed exhaust path through which the exhaust gas passes, wherein the plurality of exhaust trap sections includes a first exhaust trap section arranged at an upstream side in a flow direction of the exhaust gas and a second exhaust trap section arranged at a downstream side in the flow direction of the exhaust gas, wherein the first exhaust trap section is provided with one or more collision plates arranged to interrupt an exhaust gas flow moving along an axis of an exhaust path of the first exhaust trap section, the collision plates being arranged such that a space extending continuously along the axis of the exhaust path without being interrupted by any of the collision plates arranged within the exhaust path exists in the exhaust path, and wherein the second exhaust trap section is provided with a plural number of collision plates arranged to interrupt an exhaust gas flow moving along an axis of an exhaust path of the second exhaust trap section, the plural number of collision plates being arranged such that a space extending continuously along the axis of the exhaust path without being interrupted by any of the collision plates arranged within the exhaust path does not exist in the exhaust path.
