Tail-gas detection device

Abstract

The invention disclose a tail-gas detection device. The tail-gas detection device comprises a metal shell, a detection module is arranged in the metal shell and comprises a reagent storage cavity used for storing a reagent, a protective film adheres to the outer surface of the reagent storage cavity, and the protective film is prepared from, by weight, 1-2 parts of lignosulfonate, 1.4 parts of ethylene distearamide, 0.7 part of fiber brucite, 0.9 part of organic bentonite, 0.3 part of aluminum residue fine powder, 0.7 part of mica powder, 1.4 parts of ferricyanate, 1.7 parts of barium petroleum sulfonate, 0.7 part of hexyldecanol and 12.6 parts of petroleum resin. According to the tail-gas detection device, the protective film adheres to the outer surface of the reagent storage cavity which has good corrosion resistant, antioxidant, anti-static, heat resistant, cold resistant and weather resistant performance, it is guaranteed that the reagent is not affected by the external, and the detection stability is guaranteed.
