Abstract
A premixing flammable gas ignition device used for the gas ash blower, which comprises a flammable gas inlet pipe, an air inlet pipe, a plug, a mixing chamber, a mixing chamber outlet pipe, a fire hinder, an ignition chamber inlet pipe, a three way fitting, a plug, an ignition chamber, an ignition chamber outlet pipe and an igniter. The model is characterized in that the ignition chamber is connected with the three way fitting with a plug, the center axis of the connecting plug and the ignition chamber three way fitting two ends is concentric, but the axis of the ignition chamber inlet pipe and the two ends of the three way fitting connecting with the ignition chamber and the plug is 90 degree, the diameter of the mixing chamber is larger than or is equal to the outlet diameter of the mixing chamber, the diameter of the ignition chamber is equal to the outlet diameter of the ignition chamber. The model is able to be a mixing ignition device for the ash blower and to meet the reliability of the ignition and the requirement of the exploding or firing return prevention as well.
Description
Affiliated field
The utility model relates to a kind of flammable premixed gas body mixed firing device that is used for gas soot blower, especially can effectively prevent the flammable premixed gas body mixed firing device of detonation tempering.
Background technology
It is by the flammable premixed gas body being forced the technology that the detonation shock wave carries out the top blast ashes that are heated such as boiler that produces of lighting that ash is blown in combustion gas, because it blows the advantage that grey energy is big and dry type is blown ash, commercial Application more and more widely, this just requires the flammable premixed gas body mixed firing device of one of critical component can satisfy the requirement that igniting reliably can effectively prevent detonation pipeline tempering upstream again.At present, normally adopt the method for " blocking up ", prevent the detonation tempering, all exist to prevent the unfavorable problem of detonation tempering effect, and too little aperture can increase the possibility of pipeline blockage as adopting the resistance that bores littler aperture or increase upstream line.
Summary of the invention
For the deficiency of the flammable premixed gas body mixed firing device that overcomes present use, the utility model provides a kind of flammable premixed gas body mixed firing device that is used for gas soot blower, and this device can not only guarantee reliable mixed firing, and can prevent the detonation tempering.
The utility model is by the combustible gas air inlet pipe, air intake duct, plug, mixing chamber, the mixing chamber outlet pipe, spark arrester, the igniting chamber inlet tube, threeway, plug, igniting chamber, igniting chamber outlet and igniter constitute, it is characterized in that igniting chamber is connected with the right-angle tee that has plug, the two-port central axis of the threeway of connection plug and igniting chamber is concentric, and the igniting chamber inlet tube becomes 90 ° with the threeway two-port central axis that is connected plug and igniting chamber, the diameter of mixing chamber is more than or equal to mixing chamber outlet pipe diameter, igniting chamber diameter or equal the igniting chamber inlet tube and igniting chamber outlet diameter.Combustible gas and air form the flammable premixed gas body in mixing chamber, enter igniting chamber through spark arrester and igniting chamber inlet tube, behind the igniter forced ignition, produce instantaneous detonation shock wave (being about a few tens of milliseconds action time), this detonation shock wave rushes at igniting chamber simultaneously and comprises igniting chamber outlet, igniting chamber inlet tube and igniting chamber plug.Rush at the igniting chamber importer to the detonation shock wave directly rush at plug, hindered the weakening of turning back; And the igniting chamber inlet tube becomes 90 ° with the two-port central axis of the threeway that is connected plug and igniting chamber, and effect reduces the detonation shock wave to the igniting chamber inlet tube, and is provided with spark arrester, thereby has prevented the pipeline propagation upstream of detonation flame effectively.
The beneficial effects of the utility model are when guaranteeing the reliable mixed firing of flammable premixed gas body, and system safety operation has been guaranteed in assurance detonation pipeline tempering upstream, and is simple and reliable for structure in addition, is easy to processing and manufacturing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
