EXPLOSION-PROOF APPARATUS FOR MEASURING CONCENTRATION OF RESIDUAL CHLORINE

WIPO Patent Application WO/2020/179997

A1

The present invention relates to an explosion-proof apparatus for measuring the concentration of residual chlorine, the apparatus comprising: a measurement unit including a light-emitting part and a light-receiving part and having a sample water inlet pipe through which sample water is introduced and a sample water discharge pipe through which sample water after completion of measurement is discharged; a reagent storage unit including a reagent inlet pipe so as to introduce a reagent into the measurement unit; a control unit which, after light generated by the light-emitting part passes through sample water, measures the concentration of an oxidant in the sample water on the basis of a signal received by the light-receiving part; an inlet valve and a discharge valve installed in the sample water inlet pipe and the sample water discharge pipe, respectively; and a reagent injection means installed in the reagent inlet pipe so as to control the inflow of a reagent, wherein the inlet valve, the discharge valve, and the reagent injection means are formed to have an explosion-proof encapsulation structure, whereby the maintenance of the apparatus can be conveniently performed without a need to feed air.
