Steam jet flow type tank car cleaning method and device thereof

Abstract

The invention relates to a steam jet flow type tank car cleaning method which mainly comprises the steps of: aligning a tank car, extracting residual material, aligning a cleaning machine, adopting the inner wall of the steam jet flow cleaning tank car at the short distance, carrying out purification treatment on waste gas and waste water, and automatically controlling the cleaning of the cleaning machine. The equipment cleaning machine specially designed for the cleaning method comprises an up and down stretching mechanism of the cleaning machine, a tank hole sealing mechanism, a transverse stretching mechanism of the cleaning machine, a spray head and a steam pipeline. The stretching distance of the transverse stretching mechanism of the cleaning machine can be controlled by a stroke control mechanism. Compared with the prior art, the railway tank car inner wall cleaning method and the device thereof are safer, less in investment, energy-saving, wide in cleaning range and high in efficiency.

Description

technical field [0001] The invention relates to a method and equipment for cleaning the inner wall of a railway tank car. technical background [0002] At present, one of the cleaning methods for the inner wall of railway tank cars in my country is to use the method of steam washing, which uses the heat energy of steam to clean the inner wall of the tank car, and after extracting the residual liquid in the tank, it is fumigated by steam for 6-8 hours, and the sewage is drawn out, residues are removed, and hot air drying , the cleaning efficiency of this method is low, the cleaning effect is poor, the manual cleaning workload is large, and a large amount of oil gas or toxic chemical substances are vaporized and discharged into the atmosphere during the fumigation and drying process, which pollutes the environment and damages the health of workers; the other is to use high-pressure water The jet cleaning method uses the kinetic energy of high-pressure water to clean the inner wa...

Problems solved by technology

[0002] At present, one of the cleaning methods for the inner wall of railway tank cars in my country is to use the method of steam washing, which uses the heat energy of steam to clean the inner wall of the tank car. After extracting the residual liquid in the tank, it is fumigated by steam for 6-8 hours, and the sewage is extracted, residues are removed, and hot air is dried. , this method has low cleaning efficiency, poor cleaning effect, heavy manual cleaning workload, and a large amount of oil gas or toxic chemical substances are vaporized and discharged into the atmosphere during the fumigation and drying process, polluting the environment and damaging the health of workers; the other is to use high-pressure water The jet cleaning method uses the kinetic energy of high-pressure water to clean the inner wall of the tank car. This method has high cleaning efficiency, high labor intensity for operators, and less harm to the body. However, this method has many high-pressure equipment and pipelines, and there are unsafe factors, and the cleaning noise is large. , high energy consumption, poor cleaning effect for viscous medium or medium that will condense at low temperature (such as diesel oil), and large investment in equipment
