Dry quenching boiler tube explosion monitoring safety device

Abstract

The utility model discloses a dry quenching boiler tube explosion monitoring safety device which comprises a PLC control device and a sensor group arranged on a boiler, and the sensor group is used for detecting the pressure value and the moisture and / or gas content in the boiler. And the PLC control device is used for cutting off the operation of the circulating fan, the dust removal fan, the baffle plate of the bag-type dust remover, the cold coke conveying belt and the dust conveying belt according to the pressure value and the moisture and / or gas content. The PLC control device is arranged, through the principle that the pressure of hydrogen, oxygen and the like rises after high temperature due to water vapor generated by pipe explosion, gas pressure rise such as online hydrogen rise and oxygen rise is achieved through the sensor set, and equipment and personnel injury caused by malignant pipe explosion accidents is avoided by linkage to a circulating fan and a ground dust removal fan; pipe explosion can be accurately judged through multiple tests, the accuracy is 100%, and terrible accidents are prevented.
