A jet cleaning method

Abstract

The invention relates to a jet flow cleaning method, and belongs to the field of industrial cleaning. According to the method, firstly cleaning sand and cleaning liquid are put into a tank body of a jet flow cleaning device; a jet-out pipeline of the jet flow cleaning device is closed; a body pipeline is internally filled with high-pressure gas through a gas source; when the gas pressure in the body pipeline reaches a first preset value, the body pipeline is lifted up along an installing hole, and breaks away from a gas inflow nozzle, and the cleaning sand, the cleaning liquid and the filled gas are mixed in the tank body; and when the gas pressure in the tank body reaches a second preset value, the jet-out pipeline is started, a mixture of the cleaning sand, the cleaning liquid and the filled gas is jet out, and jet flow cleaning is performed. According to the jet flow cleaning method, a high-pressure water source is not needed, and the cleaning energy consumption is greatly lowered;and due to gas, liquid and solid three phases are pre-mixed, the cleaning sand is uniformly distributed in a three-phase mixture, pipeline blockage caused when the cleaning sand is concentrated and accumulated is avoided, the using safety of the device is prolonged, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to a cleaning device and a cleaning method based on a three-phase fusion jet, belonging to the field of industrial cleaning. Background technique [0002] my country's industrial cleaning industry is a new industry with only 20 years of development history. After 20 years of rapid development, great progress has been made. Industrial cleaning is generally divided into chemical cleaning, physical cleaning and biological cleaning. According to the National Bureau of Statistics, physical cleaning accounts for about 30% of the overall industrial cleaning market, and cleaning methods such as high-pressure water jets and air sandblasting dominate. [0003] Air blasting method is a physical method of paint and rust removal. The quality of rust and paint removal is high, and the surface roughness is good. It has a high efficiency of rust and paint removal for large equipment. But its disadvantages are: a large amount of dust will be ge...

Problems solved by technology

But its disadvantages are: a large amount of dust will be generated during operation to pollute the environment, which will seriously endanger the health of operators. Long-term use of this method will damage the surface of objects (such as hulls, wagons, carriages, etc.); trouble

But its disadvantages are: to meet the efficiency and effect of paint removal and rust removal operations, the general injection pressure needs to reach about 2000 kg, and there is a certain risk in operation; the water and electricity consumption is large, and the energy consumption is high;

This wet sandblasting method requires not only a high-pressure air source, but also a high-pressure water source (usually 0.5MPa), which has the disadvantages of high energy consumption and high safety risks.
