Problems solved by technology

In the pulverized coal system, in order to avoid pulverized coal combustion and explosion caused by dust accumulation, anti-riot valves, fire extinguishing devices or automatic monitoring devices are generally installed in the air ducts containing pulverized coal. Due to limited investment, CO detection at some key points Can only give up, the result is to increase the security risks of the production system

Abstract

The invention discloses a pulverized coal workshop safety auxiliary device and method based on sensor detection. The device comprises a CO detection controller, the CO detection controller is used for controlling a sample gas treatment unit and a gas sensor connected to the sample gas treatment unit, the sample gas treatment unit is connected with a sampling probe via a sampling pipeline, the gas sensor is provided with a sound-light alarm device and a linkage device, the linkage device can drive a gas storage tank to open a discharge valve thereof, and the CO detection controller is also connected with a temperature sensor. The device and the method have the advantages that the sensor integrated control type CO detection device directly wall-mounted nearby a sampling point is simple, practical and low in cost, saves the debugging time, realizes real-time online continuous monitoring on the potential risk of a pulverized coal system and really improves the technical level of safety production.

Description

technical field [0001] The invention relates to the field of electronic communication used in the production and processing of pulverized coal, in particular to a safety auxiliary device and method for a pulverized coal workshop based on sensor detection. Background technique [0002] The pulverized coal preparation workshop is a flammable and explosive place. Although effective measures have been taken in the manufacture of the host equipment, due to the different characteristics of coal quality, the system is inevitably in danger of accidental combustion and explosion. Among them, the explosion factors mainly include the concentration of pulverized coal, the CO content and oxygen content in the gas mixture, and the temperature seriously exceeding the standard. If there is an open flame source, an explosion will occur. Coal powder accumulated for a long time is prone to spontaneous combustion when the temperature rises. Generally, it is inert gas (CO 2 , N 2 ) and foam, p...
