Closed energy-saving and environment-friendly tank truck cleaning device and cleaning method thereof

Abstract

The invention relates to a closed energy-saving and environment-friendly tank truck cleaning device which comprises a tank truck and an air bag type closing cover plate, wherein the air bag type closing cover plate is connected with a nitrogen input pipe, a cooking steam input pipe, an exhaust fan and a drying fan respectively, and is also connected with an alkali liquid washing basin, a detergent washing basin, a chemical agent washing basin, a high-pressure water washing basin, a low-pressure water washing basin, a water washing basin and a heat exchanger respectively; the heat exchanger is connected with a steam washing pipeline and an industrial water supplementation pipeline respectively; the air bag type closing cover plate is connected with a residual liquid basin, an oil-water separator, a wastewater sedimentation treatment basin, a residual acid basin and a lime reaction sedimentation basin in sequence; the wastewater sedimentation treatment basin is connected with the alkali liquid washing basin, the detergent washing basin, the chemical agent washing basin, the high-pressure water washing basin, the low-pressure water washing basin and the water washing basin respectively; and an industrial air stirring device is connected with the alkali liquid washing basin and the chemical agent washing basin. Meanwhile, the invention further discloses a cleaning method for the device. The closed energy-saving and environment-friendly tank truck cleaning device and the cleaning method thereof are safe and convenient to use, and good in cleaning effect.

Description

technical field [0001] The invention relates to the technical field of cleaning oil refineries, chemical plants, trestle tank cars of various chemical products, and storage tanks, and in particular relates to an airtight, energy-saving and environment-friendly tank car cleaning device and a cleaning method thereof. Background technique [0002] At present, when oil refineries, chemical plants, trestle tankers and storage tanks of various chemical products are being cleaned, the residual liquid in the tanker and storage tanks will produce a large amount of nitric oxide, nitrogen dioxide, benzene, Toxic and harmful gases such as aromatic hydrocarbons, olefins and nitrogen oxides, these toxic and harmful gases are discharged into the atmosphere in an extensive manner, and at the same time, the residual liquid wastewater from tank trucks and storage tanks is discharged into the air without harmless treatment during the cleaning process. Sewers are not only not conducive to safe ...

AI Technical Summary

Problems solved by technology

[0002] At present, when oil refineries, chemical plants, trestle tankers and storage tanks of various chemical products are being cleaned, the residual liquid in the tanker and storage tanks will produce a large amount of nitric oxide, nitrogen dioxide, benzene, Toxic and harmful gases such as aromatics, olefins and nitrogen oxides, these toxic and harmful gases are discharged into the atmosphere in an extensive manner, and at the same time, the residual liquid wastewater from tank trucks and storage tanks is discharged into the air without harmless treatment during the cleaning process. Sewers are not only detrimental to safe production and personal safety, but also cause great damage to the human respiratory system and skin, and at the same time cause great damage to the environment and cause great waste of water resources

[0003] In addition, when using the traditional method to clean the tank truck storage tank, no monitoring measures are used in the whole process. Therefore, the water consumption is huge, and the water quality cannot meet the standard; Secondary pollution, because the cover locker is not set, once the pressure in the cleaning pipeline is too high, it will cause the airbag type airtight cover to float up and down, affecting the recovery quality
