Deflagration generator

Technical Field

The utility model relates to a deflagration generator belongs to petrochemical trade tail gas treatment technical field.

Background

The existing torch ground transfer combustion type igniter has the following principle: the instrument air and fuel gas for ignition enter the mixing chamber through respective pipelines and a flow-limiting orifice plate (or a pressure reducing valve), when the concentration of the instrument air and the fuel gas reaches a chemical concentration range, the instrument air and the fuel gas are ignited by electric sparks generated by high-voltage discharge of a high-energy semiconductor electric nozzle and are detonated, and generated flames are transmitted to the pilot burner along the pipelines and ignite the pilot burner.

The existing ground transfer combustion type ignition mode of the torch is characterized in that: firstly, air and fuel gas are respectively connected into a mixing chamber to be naturally mixed, and the mixing effect is poor under the influence of respective gas flow and pressure of an air pipeline and a fuel gas pipeline; secondly, the concentration of the mixed gas is only between the upper explosion limit and the lower explosion limit, the mixer can deflagrate when sparks exist, the propagation of flame after deflagration is also influenced by the concentration of the mixed gas in the pipeline, and the deflagration success rate of the mixer is only 50 percent generally.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, a detonation generator, including mixing chamber pipe 1, gas takeover 2, air takeover 3, the igniter rod takeover 4 and igniter rod 5, gas takeover 2 is installed to the front end of mixing chamber pipe 1, deflagration gas export 6 is installed to the rear end of mixing chamber pipe 1, deflagration gas export 6 is the toper structure, mixing chamber pipe 1, gas takeover 2 and deflagration gas export 6 set up with one heart, air takeover 3 is installed to the front portion top of mixing chamber pipe 1, air takeover 3 extends to in the mixing chamber pipe 1, and the bottom of air takeover 3 is sealed, still be provided with a plurality of mixing hole 7 on the circumference of air takeover 3, igniter rod takeover 4 is installed to the rear portion top of mixing chamber pipe 1, igniter rod 5 is installed in igniter rod takeover 4, the igniter head of igniter rod 5 is located mixing chamber pipe 1.

The utility model discloses well air is taken over 3 and is stretched into 1 intraductal bottom in mixing chamber pipe, and 3 vertical settings are taken over to the air, and the bottom that 3 were taken over to the air is located the axis below that 2 were taken over to the gas, 3 lower extremes are taken over to the air and is sealed, stretch into some pipe lateral wall border and open if dry mixing orifice, make the flow direction variety of air admission mixing chamber pipe 1, and with the gas contact surface greatly increased who gets into mixing chamber pipe 1, the speed and the homogeneity of gas mixing obtain obvious enhancement, thereby reach the purpose that gas and air intensive mixing reach deflagration concentration rapidly, the effectual success rate that has improved system deflagration.
