Improved diffused mixed pulse soot blowing method pulse sootblower adopting the method

Abstract

The invention belongs to the thermal explosion pulse soot blowing technical field and in particular relates to an improved diffused and mixed pulse soot blowing method and a pulse soot blower by adopting the method. The method mainly comprises that: firstly, oxidant gas with the volume equal to or more than the cubage of a pulse tank is filled into a pulse generator, then fuel gas is filled to the pulse generator; after a period of time, the gas mixture of the fuel gas and the oxidant gas in the pulse generator is detonated; a fuel pipeline and an oxidant pipeline of the pulse soot blower are respectively connected with an entrance end of the pulse generator. The improved diffused and mixed pulse soot blowing method and the pulse soot blower by adopting the method have the main advantages of leaving out the special sweeping process, avoiding backfire and improving safety.

Description

Improved Diffusion Mixing Pulse Sootblowing Method and Pulse Sootblower Adopting the Method technical field The invention belongs to the technical field of thermal explosion pulse soot blowing, and in particular relates to an improved diffusion mixing pulse soot blowing method and a pulse soot blower adopting the method. Background technique Thermal explosion pulse sootblower is referred to as pulse sootblower, also known as shock wave sootblower, shock wave sootblower, weak explosion sootblower, detonation wave sootblower, detonation wave sootblower, detonation pulse sootblower, etc. , was first invented by the former Soviet Union and introduced to my country in 1988. It evolved from the "gas cannon". Internal ignition explosion, using the "alternating stamping and suction effect" of the compression shock wave generated by the explosion, the "physical micro-explosion effect" and the "purge effect" of the high-speed pulse jet to blow off various accumulations on the heating ...

AI Technical Summary

Problems solved by technology

Existing pulse sootblowers all include a special mixer. The fuel gas and oxidant gas flow through the mixer together to form a premixed gas, and then flow into the pulse generator. Once the inflation is completed, the gas will be ignited and detonated immediately. , this method mainly relies on the lateral movement of the microfluidic mass in the turbulent state to realize the mixing of fuel gas and oxidant gas, and the mixing time is very short, which not only requires a high mixing flow rate in the mixer, but also leads to a large loss of fluid resistance , and the requirements for the mixer itself are also very high. Once the ideal mixing effect is not achieved, it will not only affect the explosion strength, but also produce more carbon deposition during the explosion. After a long time, it will not only block the flow channel, but also It will cause a short circuit in the ignition head, lead to ignition failure, or even burn out the ignition power supply
