Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0016] It is known from aerodynamics that when the high-pressure gas in a confined space contacts the low-pressure gas in a very short period of time, a compression wave will be formed on its front, and in the shock tube, the front compression wave will be continuously strengthened and accelerated. Finally, a shock wave of a certain intensity is generated. The formation and intensity of this kind of shock wave are largely determined by the time of instantaneous contact between high-pressure gas and low-pressure gas, that is, the so-called membrane rupture time. When it reaches a certain critical value, a shock wave can be generated. The shorter the shock wave The greater the intensity.

[0017] The gas energy pulse soot blower of the present invention just utilizes this prin...

Abstract

The invention discloses a gas energy pulse soot blower utilizing compressed gas, which comprises a plurality of groups of pulse shock wave generators, wherein each group of pulse shock wave generator comprises a solenoid valve for controlling the group of gas supply branch circuit to switch on / off, a pulse tank for generating shock waves, and a releaser for releasing the shock waves, and each group of gas supply branch circuit is communicated with a compressed gas generating device through a gas transmission pipeline. The gas energy pulse soot blower utilizing the compressed gas disclosed by the invention takes the compressed gas as the gas energy for boiler soot blowing, the cost is lower, the generated shock wave energy is larger, the soot blowing effect is more obvious, and the soot blower has a simple structure, low failure rate and is safer and more reliable.

Description

technical field [0001] The invention relates to a soot blower, in particular to a gas energy pulse soot blower utilizing compressed gas. Background technique [0002] At present, the soot blowing equipment installed in power plant boilers are mainly steam soot blowers and sonic soot blowers. [0003] The steam soot blower is a traditional soot blower, which is the most used at present. Due to the characteristics of the structure and medium, and the influence of the high temperature environment, the soot blower barrel is prone to jamming, failure, and steam leakage, and the equipment failure rate is relatively low. High, requiring a high level of maintenance. [0004] The sonic soot blower, due to insufficient energy (currently the maximum sound energy is about 140 decibels), is very different from the natural frequency of the ash particles, and is not suitable for the characteristics of ash accumulation. The soot blowing effect is very poor, and basically cannot remove the ...
