Abstract

The invention provides a sewer gas security detection device, which is applicable to the field of gas security monitoring and comprises a preprocessing module, a gas detection module, a microprocessor and a wireless transmission module. The sewer gas security detection device collects sewer gas and performs dry filtering processing on the sewer gas through the preprocessing module. The gas detection module detects the sewer gas performed with the dry filtering processing and then outputs gas concentration value. The microprocessor compares the gas concentration value with a set threshold and outputs gas concentration information. The wireless transmission module transmits the gas concentration information output by the microprocessor to a monitoring center, so that the monitoring center can obtain concentrations of poisonous, harmful, inflammable and explosive gas in the sewer gas in real time, safely process the poisonous, harmful, inflammable and explosive gas in a sewer timely, and accordingly the problems of casualties and property loss caused by leakage of the poisonous, harmful, inflammable and explosive gas is avoided.

Description

technical field [0001] The invention belongs to the field of gas safety monitoring, in particular to a sewer gas safety detection device. Background technique [0002] With the continuous improvement of people's living standards and the increasing emphasis on environmental protection, higher requirements are put forward for the detection of various toxic, harmful and flammable gases, the monitoring of air pollution, industrial waste gas, and the detection of food and living environment quality . [0003] Urban municipal sewer is one of the important infrastructures of the city. Due to its relatively closed and special environment, it is easy to produce a large amount of toxic, harmful, flammable and explosive gases (such as H2S, CO, NH3, O2 and combustible gases). , When dangerous gas leaks, it is easy to cause gas accumulation, explosion in case of open fire and other accidents. In recent years, there have been serious sewer explosion accidents, and gas poisoning incident...
