Provided is an apparatus for stably removing plugging even in a state in which combustible gas or liquid remains in a pipe and precisely removing plugging even using small force.

Drill device for removing plugging inside pipe

An anchor bolt machining apparatus including an anchor bolt machining die and a die holder. The anchor bolt machining die includes a first head portion for fixing an anchor bolt and a first body portion receiving a screw machining die and the die holder includes a second head portion coupled to a rotational force supply device, a support portion coupled to the anchor bolt machining die, and a second body portion connecting the second head portion and the support portion.

Anchor bolt machining apparatus

A heat exchanger including: an inlet portion having a first flow path through which a fluid is introduced; a main body including a shell and a plurality of tubes. The shell has an internal space and one surface that has a plurality of penetration holes and a cross-sectional area larger than a cross-sectional area of the first flow path. Each of the plurality of tubes allows the fluid to flow therethrough, and is positioned in the internal space of the shell. An expanded tube portion connects the inlet portion and the one surface of the shell and has a second flow path. The heat exchanger also includes a fluid flow distributor disposed in the second flow path to distribute the flow of the fluid. No other member is disposed between the inlet portion and the multiple ring members.

Heat exchanger

A drill device for removing plugging in pipes, the drill device including: a drill bit for breaking plugging in pipes; a vertical control handle capable of controlling a vertical movement of the drill bit; a drill handle capable of controlling a rotational movement of the drill bit; a screw disposed coaxially with the drill bit; a drill shaft having a first portion surrounding the screw and a second portion to which the drill bit is fixed; and a guide shaft surrounding the first portion of the drill shaft. The vertical control handle and the drill handle are disposed on an extension line of the axis of the screw; the screw is vertically moved by rotations of the vertical control handle; and the guide shaft is rotated by rotations of the drill handle, and in conjunction therewith, the drill bit can be rotated.

Drill device for removing plugging in pipes

A selective catalytic reduction (SCR) system having a catalytic layer. The SCR includes a plurality of baffle members located in a position spaced apart from a front end of the catalytic layer, the plurality of baffle members reduces a flow deviation due to enlargement of a flow cross-section of a fluid in at least one direction, each of the plurality of baffle members includes a first part and a second part, the first part and the second part of each of the plurality of baffle members extends in an orthogonal direction with respect to the at least one direction of enlargement of the flow cross-section, the first part and the second part are integrated, and each of the plurality of baffle members protrudes in an inlet direction of the fluid.
