TH61884B - Exhaust gas purification equipment - Google Patents

Abstract

New request revised 03/03/2016 The exhaust gas purification equipment includes a catalyst provided to exhaust gas flow path and the restraint piece, which is arranged on the end of the catalyst in exhaust gas flow path and reduce bias in the gas flow rate distribution Exhaust which flows to the catalyst by suppressing the partial flow of exhaust gas which flows from the catalyst where the suppressor consists of a wide shaped concave facing to the catalyst. List and inhibit the partial flow of exhaust gas which flows from the catalyst by concave section.

Disclaimer (all) which will not appear on the advertisement page: Revised 24 Aug 2017 1. The exhaust gas purification device incorporates a catalyst that is supplied to the flue gas flow path in the flow path component; The inhibition element is arranged in the exhaust gas flow path and reduces bias to distribute the flue gas flow rate, which flows to the catalyst by partially inhibiting the flow. Of the exhaust gas where the suppression part is arranged only on the catalyst's end side and is assembled Combined with a vane-shaped concave section with a closed bottom face, closed gas flow and a support supporting the suppressor in a pre-determined position to allow the deterrent element Turn to the catalist The support is included. The pinned part that is fixed to the flow path element and the connections which connect the concave and the riveted part. Where the connector extends in line Outward radius from the concave part parallel to the catalist end-of-face surface. Where the support supports the suppressor in position so that the concave is facing the part of the The surface of the catalyst end-end -------------------------------------------------- -------------------------------------------------- New requests updated 18/03/2016 1. The exhaust gas purification device consists of a catalyst that is supplied to the exhaust gas flow path and an inhibitor which is arranged on the destination side of the catalyst in the route. Gas flow Exhaust gas and reduce bias to distribute the flow rate of the exhaust gas which flows to Catalyst by inhibiting the partial flow of the exhaust gas flowing from the catalyst where the inhibition part is composed of a hollow-shaped concave that turns to the catalist and inhibits Partial flow of the exhaust gas which flows from the catalyst by the concave part. 2. Exhaust gas purification device according to claim 1, where the recess is made gradually smaller towards the destination side of the flue gas flow path. 3.
