How often should the underground 18T diesel tanks in the factory be cleaned and how should they be c

If there is no abnormality, it does not need to be cleaned.

In fact, diesel engines are cleaner than gasoline engines, and there is no clear limit on particulate matter emissions from gasoline engines before the fourth stage of the European automobile exhaust emission regulations, indicating that the PM emissions of diesel engines are indeed more serious than gasoline engines and must be controlled. However, with the emergence of GDI in-cylinder direct injection gasoline engines, gasoline engine emission particle pollution has also attracted attention, and the PM emissions of GDI gasoline engines have been clearly defined in the Euro V emission standards, which is equivalent to the PM emission limit of diesel engines. Gasoline and diesel were tied on the PM.

Let's take a look at other contaminants. Diesel engines are significantly lower in CO and HC emissions than gasoline engines, and higher in NOx emissions. Of the four major pollutants, diesel engine wins.

Let's not forget CO2, the main culprit of climate change. If you take into account the indisputable fact that the average thermal efficiency of diesel engines is higher than that of gasoline engines, do you still think that diesel engines have higher emissions than gasoline engines? In addition, the diesel engine before Euro III did not need to use the emission climate treatment system to meet the emission regulations, and the gasoline engine needed a three-way catalytic system to meet the emission regulations.

In the future, GDI will become the mainstream trend of gasoline engines, and how to solve the particulate emissions caused by it has also been officially put on the agenda. For diesel engines, as the pressure of high-pressure common rail is getting higher and higher, and with the maturity of multi-pole supercharging, DPF, EGR, SCR and other technologies, diesel will become more and more a clean and efficient energy source. (Note that I didn't say that diesel is a "fossil energy with socialist characteristics", so in the foreseeable future in China, diesel engines will mainly be in the form of black smoke and will not be promoted in any way.)

And considering the engine emission certification system with Chinese characteristics, it is basically not cost-effective and impossible for Chinese to spontaneously produce clean diesel engines. As for electric cars, I think it's more of a joke at this stage. No one wants a heavy car to be charged once for 200km, not to mention that there is no power plug in my garage.

If I had to choose, diesel-electric hybrid is the future. VW seems to already know about this. And did you know that the diesel-powered Audi won the Le Mans Cup (now the World Endurance Championship WEC) for several years?

This year's WEC Audi's diesel-electric hybrid is also almost on the verge of winning the championship. More than 50% of passenger cars in Europe are diesel-powered. European countries recognize that diesel is actually a non-inferior energy source, in order to encourage the promotion of clean diesel The United States imports Pvesun Tmall effective anti-fog engines, and Europe, especially in Germany, even subsidizes diesel fuel to offset the disadvantage of diesel engines being more expensive than gasoline engines, and is used to promote clean diesel engines.

Rent a high-pressure steam truck and inject high-pressure steam into the tank. According to the degree of oil stain in the tank, the steaming time is determined. After the steam is cooled twice, it will be degreased.

Plastic buckets, after being filled with diesel, it is better not to hold edible things, the oil has seeped into the plastic.

Characteristics: Water-based high-efficiency degreasing and cleaning agent is scientifically compounded with a variety of alkali lotion agents and high-efficiency active agents. It has the effect of soaking, emulsifying, dispersing and cleaning on animal and vegetable oils and mineral oil scales.

Commonly used organic solvents (such as gasoline, etc.) and general lye degreasing cleaners can only remove general metal surfaces.

Fission decomposition agent with gas, diesel, coal, and heavy oil.

I'm a professional in this, so 13874781396 can consult me.

1. Drain the oil in the tank;

2. Ventilate the oil and gas in the tank, and measure the concentration to a safe range;

3. Personnel enter the tank to clean oil, water and other sediments;

4. Cleaning with steam, this method is mainly used to clean the viscous oil tank;

5. Clean the oil with high-pressure water, drain the sewage, and dry clean with sawdust;

6. Remove sawdust and remove local rust with copper tools;

7. Thoroughly remove the dirt with a mop;

Rent a high-pressure steam truck and inject high-pressure steam into the tank. According to the degree of oil stain in the tank, the steaming time is determined. Not once, twice.

After the steam is cooled, it enters and degreases.

4. Cleaning with steam, this method is mainly used to clean the viscous oil tank;

Many people use Super Universal Emulsifier mixed with water to clean, and the effect is very good.

Hello, this needs to be cleaned vigorously by laundry detergent, you can add laundry detergent and then wash it with a high-pressure water gun.

The idea on the first floor is a bit of a cover-up. Does no taste mean no ingredients? Diesel does not dissolve in vinegar, one is lipophilic and the other is hydrophilic, and there is no similarity in performance at all.

The composition of diesel and gasoline is similar, and the principle of similarity and solubility can be adopted, and some gasoline can be dissolved and diluted first. Then leave it for a while and wait for the gasoline to completely evaporate clean. Then wash repeatedly with dish soap, don't be afraid of trouble, wash repeatedly.

Don't add something with an smell to cover up the smell of diesel, the consequences will be serious!
