Integrated intelligent flame detection device

Abstract

The invention discloses an integrated intelligent flame detection device, which comprises a flame sensor, a selective filter module, an automatic gain amplification module, a central processing module, a first path voltage detection module, a second path voltage detection module, a display module, a communication module and an output module. The input end of the selective filter module is connected with the output end of the flame sensor to filter data sensed by the flame sensor and send the filtered data into the automatic gain amplification module; the input end of the first path voltage detection module is connected with the flame sensor, while the output end of the first path voltage detection module is connected with the central processing module; the input end of the automatic gain amplification module is connected with the selective filter module and the central processing module, while the output end of the automatic gain amplification module is connected with the second path voltage detection module; and the input end of the central processing module is further connected with the second path voltage detection module, while the output end of the central processing module is respectively connected with the display module, the output module and the communication module. The device can be used for effectively solving the peeping problem of the existing structure, therefore, the stability and the safety of the flame combustion are ensured, the economical efficiency is good and the maintenance is easy to realize.

Description

technical field [0001] The invention belongs to the field of electronic measurement and control, and relates to a flame detection system for various fuel oil, coal-fired and gas-fired boilers, in particular to an integrated intelligent flame detection device. Background technique [0002] With the increasing use of boilers in the fields of large-scale thermal power generation, petrochemical power stations, urban heating, and blast furnace waste gas combustion, the safety of boilers is becoming more and more important to personnel safety, economic benefits, and social stability. Therefore, in order to prevent internal explosion and external explosion of boilers and reduce the occurrence of boiler explosion accidents, the state stipulates that large boilers must be equipped with a "boiler furnace safety monitoring system (FSSS)", and the flame detection equipment is the core of the FSSS system. [0003] At present, most of the domestic use split flame detection devices, but ...

AI Technical Summary

Problems solved by technology

[0004] (1) The concept and technology of flame detection in the early stage were not very perfect, which made the occurrence of peeking problem unavoidable;

[0005] (2) The split-type flame detector is composed of a flame detector probe and a flame detector processor, and cables are needed to connect the two, which increases the complexity and difficulty of maintenance
