Abstract

The present invention pertains to an exhaust gas treatment device for a construction machine. More specifically, in an exhaust gas treatment device for a construction machine, which is connected to a diesel particulate filter trap (DPF) and discharges exhaust gas passing through the DPF from an engine to the outside, the device includes: a tail pipe main body having a plurality of ventilation holes which are penetrated such that outside air passes through the inside thereof and mounted to the outlet of the DPF; and an exhaust and radiation section which has a plurality of tubes respectively communicating with each of the ventilation holes and mounted in the traverse direction with respect to the tail pipe main body. Each of the tubes has a plurality of exhaust holes which are positioned in the longitudinal direction of the tubes and penetrated in the exhaust gas discharge direction.

Description

technical field [0001] The invention relates to an exhaust gas treatment device for construction machinery. More particularly, the present invention relates to an exhaust gas treatment device for construction machinery, which is connected to a Diesel Particulate Filter (DPF) to discharge exhaust gas from an engine to the outside through the DPF, and can utilize high-temperature exhaust gas and The heat exchange effect between the pipes for guiding the outside air to reduce the temperature of the exhaust gas discharged into the air, which has the exhaust air holes in the exhaust direction so that the plurality of pipes are ventilated with the plurality of vents formed on the tail pipe body The holes are connected. Background technique [0002] A tailpipe is a tube located at the rear of a muffler for heavy equipment to direct exhaust gases that have a generally steady pressure as they flow through several locations so that the exhaust gases are expelled into the atmosphere. ...
