Out-groove energy-accumulating type supersonic cleaning process for accumulated carbon

Abstract

The invention relates to an out-groove energy-accumulating type supersonic cleaning process for accumulated carbon. In the process provided by the invention, an energy-accumulating supersonic technology is utilized to clean the accumulated carbon in the inner cavity of a fuel oil general pipe under the condition of an alkalescent solution. The process comprises the following steps: designing a supersonic vibrator into an energy-accumulating structure in the adopted device; fixing the supersonic vibrator on the ejection nozzle of the fuel oil general pipe; and pumping the solution into the inner cavity of the general pipe through a pump so that supersonic signals are transmitted to the cleanser in the inner cavity through a pipe wall, wherein since the inner cavity is necessary to allow liquids to pass through when the accumulated carbon in the fuel oil general pipe is cleaned, the inner cavity is necessary be bleached clearly after being washed. The process has the following advantages: a part is not unnecessary to be completely immersed into the solution so as to ensure that the heat insulation layer on the outer surface of the part is not influenced; the supersonic cleaning method is greatly superior to the common cleaning method; and the process is low in cost, simple in operation and high in working efficiency. The process provided by the invention ensures good operating effect and stable performance and state when in field use, thereby meeting the requirement of an engine repair technology.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to an energy-gathering ultrasonic carbon deposition process outside a tank. Background technique [0002] During the working process of the engine, under the high-temperature combustion state, the trace impurities in the oil are deposited on the surface of the parts in the form of oil coke and coke after long-term combustion, forming carbon deposits. If it is not cleaned, it will affect the performance of the parts. The commonly used cleaning method is the back pumping method. [0003] The fuel manifold is one of the important parts of the engine combustion chamber. The main material is superalloy. It is composed of main oil circuit, auxiliary oil circuit and more than 20 fuel injection nozzles. The nozzles are connected with the vortex. The working temperature of the parts in the engine is nearly 600°C, the working medium is aviation kerosene, and the working pressure of kerose...

Problems solved by technology

Obviously, using this simple mechanical method to remove carbon deposits in the inner cavity of the fuel manifold is not effective. It can only remove some debris that is not firmly attached, but basically has no cleaning effect on the carbon deposits in the pipe. The carbon deposit layer will gradually thicken, and in severe cases, it will form a blockage in the fuel main pipe and cause the engine to fail to start.

Can only take the way of replacement parts, which is quite expensive and increases the cost
