摘要

The present invention relates to an extracting device supplying fixed quantity of exhaust gas for industrial facility, and more particularly, to an extracting device supplying fixed quantity of exhaust gas for industrial facility which supplies a certain amount of exhaust gas by installing a gas supply pipe, in which two blowers are arranged in a line, at a stack and operating each blower in accordance with a predetermined input value.

主权项

1. An extracting apparatus for supplying a fixed quantity of exhaust gas for industrial facility, the apparatus comprising:
a first gas supply pipe configured to extract part of exhaust gas from a stack and including a first horizontal area located on top thereof and horizontally penetrating into a side of the stack, a vertical area vertically bent from the first horizontal area in a direction of ground, and a second horizontal area horizontally extending from the vertical area; a first branch gas supply pipe configured to be installed at a bottom side of the vertical area of the first gas supply pipe; a second branch gas supply pipe configured to be connected in parallel to the first branch gas supply pipe at the bottom side of the vertical area of the first gas supply pipe; a second gas supply pipe configured to supply exhaust gas coming from the first branch gas supply pipe and the second branch gas supply pipe to sources; a first blower configured to be operated in accordance with external power control at the first branch gas supply pipe; a second blower configured to be operated in accordance with the external power control at the second branch gas supply pipe; a first pressure gauge configured to be installed on the first branch gas supply pipe and output a contact signal if a measured internal pressure of the first branch gas supply pipe is out of a predetermined range of a first reference pressure value; a second pressure gauge configured to be installed on the second branch gas supply pipe and output a contact signal if a measured internal pressure of the second branch gas supply pipe is out of a predetermined range of a second reference pressure value; and a switching element configured to supply power to the first and second blowers in accordance with the contact signal outputted from the first and second pressure gauges.
