Pollution measurement apparatus for easily exchanging sensor

摘要

Disclosed is a pollution measurement apparatus which measures a pollutant concentration and a pollutant component in gas, and more particularly a pollution measurement apparatus for easily exchanging a sensor, which can facilely exchange only desired sensors when it is required to exchange part of multiple sensors for sensing pollution.

主权项

1. A pollution measurement apparatus for easily exchanging a sensor, comprising:
a main block in which a main passage is formed and also a gas concentration measuring sensor contacted with gas flowed in the main passage is installed; a main case in which the main block and a main operation part connected with the gas concentration measuring sensor are installed; a main inlet pipe which is protruded toward a rear side of the main case so as to be communicated with the main passage; a main outlet pipe which is protruded toward the rear side of the main case so as to be communicated with the main passage; a main body which is formed with a receiving portion that n main cases are fitted therein through a front surface thereof; and a k-th main connecting means which connects and communicates the main outlet pipe protruded toward a rear side of a k-th main case out of the n main cases and the main inlet pipe protruded toward a rear side of a (k+1)-th main case out of the n main cases with each other, wherein (n−1) main flow grooves through which the gas is flowed are formed in a rear surface of the main body, a k-th main flow groove out of the (n−1) main flow grooves is formed with a k-th main outlet hole in which the main outlet pipe protruded toward the rear side of the k-th main case is inserted so as to be communicated with the k-th main flow groove, and a k-th main inlet hole in which the main inlet pipe protruded toward the rear side of the (k+1)-th main case is inserted so as to be communicated with the k-th main flow groove, and the k-th main connecting means comprises a k-th main cover plate which is installed at the rear surface of the main body so as to air-tightly close an opening end of the k-th main flow groove, and wherein n is a natural number more than 2 and k is a natural number from 1 to n−1.
