This invention discloses a dry ice crystal particle, its preparation method, and a ceramic tile, relating to the field of ceramic tile technology. The dry ice crystal particle is prepared from a first flashing frit, a second flashing frit, and a matte frit. Since the dry ice crystal particle is composed of three frits with different refractive indices and firing temperatures, different phases can be formed due to the different firing temperatures of each frit. The differences in light transmittance and refractive index between these phases are then utilized to create a better flashing effect. Simultaneously, the matte glaze serves as a backdrop, further enhancing the display of the flashing effect.

The invention relates to a system for treating heavy hydrocarbon, which can reduce the content of heavy fraction impurities in a gas-phase component and the content of light components in a liquid-phase component by injecting a cooling aid, a separation aid and an optional gas stripping aid, thereby improving the gas-liquid separation effect. Moreover, the flash separation equipment is separated into a plurality of separation chambers which are arranged side by side through baffles, each separation chamber is provided with a steam-hydrocarbon mixture inlet and a gas phase outlet, and a high-temperature steam-hydrocarbon mixture entering the separation chamber is separated and then directly enters a downstream device from the gas phase outlet of the separation chamber. The hydrocarbon partial pressure can be adjusted without arranging a high-temperature adjusting valve on the gas phase outlet pipeline, so that the fault rate of the high-temperature adjusting valve at high temperature can be reduced, and the service life of the system can be prolonged. In addition, a cyclone hydraulic separator and a tower tray are arranged in each separation chamber, so that the gas-liquid separation efficiency and the flash evaporation effect can be improved.

This utility model discloses a novel flash atomizing nozzle for desulfurization wastewater, comprising a flash tank. One end of the splicing ring is connected to a water inlet pipe, and a sealing ring is fixedly connected to the protruding edge of one end of the water inlet pipe.

A replacement head is connected to one end of the threaded mounting ring, and a mesh pad is fixedly connected to the lower end of the inner wall of the replacement head. This novel flash atomizing nozzle for desulfurization wastewater can achieve efficient four-group atomization spraying through the atomizing nozzle main unit, replacement head, and mesh pad, resulting in better flash evaporation effect. Furthermore, the atomizing nozzle main unit, replacement head, and mesh pad can be quickly assembled and disassembled as a whole using a locking knob, splicing cover plate, and mounting groove. The replacement head and mesh pad can be quickly and independently replaced using the threaded mounting ring and threaded mounting groove. The motor slip ring can drive the connecting wire for rotation adjustment, resulting in excellent installation adaptability.
