The use of spray trucks

1

Modern society has advanced science and technology, fast information dissemination, rapid economic growth and serious side effects. The most influential is air pollution. Especially in North China, Hebei Province, led by Shijiazhuang, has been plagued by haze in recent years. The haze, this “disaster”, puts people in “toxicity”. Its main sources include motor vehicle exhaust, coal-fired exhaust gas, industrial production waste gas, and dust. Among them, dust is one of the "culprits" of haze. The dust-falling sprayer can spray micro-level water mist. The water mist and the dust particles in the air combine to form a group that falls into the ground due to the action of gravity, thereby achieving the purpose of reducing dust and reducing dust. Dust-spraying sprayers are widely used in construction sites, coal mines, cement factories, port terminals, landfills, and other places where there are many open-air dust, and can also be used as ordinary sprinklers and fire engines. The place where the dust-falling sprayer passes is just like a “drizzle”, and the dust is no longer in full swing. The ability of instantaneous dust removal is obvious to all and plays a crucial role in the construction of a green environment in the city.

In the spring, when the trees sprouted and the leaves began to grow, the flocculent began to fly around like a falling snowflake. Everyone must have seen such a scene, whether you are walking on a street road or on the campus's long trail, your hair. , clothes, trousers, and even the nose, mouth, may be their "place to settle down." Many public hawker sanitation workers complain that this kind of white hull is very annoying, especially for those who are allergic. It is best to wear hats, glasses and masks and long-sleeved underwear when going out. Some cities have used this ultra-low-volume sprayer to spray mist on the roadside willows and poplars to suppress the drift of catkins and poplars and reduce the impact on people's travel. This method is a good way to suppress the trouble caused by flying white fluff on the crowd. The use of a spray truck is very versatile. As long as you discover it, you can always explore its potential.


Single Containment LNG Storage Tank

A single containment LNG tank design is defined as a tank comprising an inner tank and an outer container designed and constructed so that only the inner tank is required to meet the low temperature ductility requirements for the storage of the product. The outer container of a single containment storage tank is primarily for the retention and the protection of the insulation and to constrain the vapour purge gas pressure, but is not designed to contain the refrigerated liquid in the event of a leakage from the inner tank, i.e. it will collapse due to brittle fracture when getting in contact with large quantities of cryogenic liquid leaking from the inner tank. Therefore a single containment LNG tank needs to be surrounded by a bund wall or dike in order to prevent uncontrolled liquid spillage. It is also referred to as a double integrity LNG container since the bund wall is considered a second barrier.

Doer's single containment storage tanks have a capacity of 200-50,000 m3 and pressure of 10-50 kPa.
