In a movie or cartoon, you can often see a story with a metal detector treasure hunt. When you find a treasure underneath, the detector will make a ring. The foreign user is really lucky to find a treasure. An adventure makes him become a Rich people!

The explorer was called Alvin and he went to explore the wasteland with his friends one day. He was halfway about to sit down and drink water. He took a metal detector and put it aside when he sat down. It was at this moment. The detector made a loud noise and when he heard it, the man immediately excitement with friends and excavated the ground.

Although the metal detectors are not necessarily valuable, this time they are really pressing against the treasure! At first it looks like ordinary stones, but after cleaning, they are crazy! The layman may at first glance think it is a peanut shell, but this is a worthless dog's head gold!

Dog-headed gold is a naturally occurring, impure grain with large, irregularly shaped nuggets. It is usually composed of natural gold, quartz, and other mineral aggregates. Someone takes the shape of a dog's head and calls it a dog's head. Some people call it horseshoe in the shape of a horseshoe; but most people call this natural block gold a dog's head gold.

It can be said that it cannot be met. All over the world, they all take pride and pride in the possession of dog-head gold. In Hebei, men once bought coal and bought a kilogram of doghead gold worth over ten million yuan.

The behead gold that Alvin and his friends dug, after expert evaluation, has a value of about 15 to 250,000 U.S. dollars.

Combined Flow Closed Cooling Tower

Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.

1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.

2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.
