A method for calculating the height and the density of a fluidized bed is described. In a first mode of operation, a first differential pressure and a second differential pressure are obtained, a bed density of the fluidized bed is calculated, and a bed height is calculated by dividing the first differential pressure by the calculated bed density. In a second mode of operation the system is purged by using a pressurized gas.

A nozzle cleaning device is capable of uniformly cleaning a nozzle from a front end of the nozzle to an upper part thereof. The nozzle cleaning device includes a storage tank, a liquid discharging portion and an overflow discharging portion. The storage tank has a cylindrical inner peripheral surface and is configured to store therein a cleaning liquid that cleans a nozzle used in a substrate process. The liquid discharging portion is configured to discharge the cleaning liquid into the storage tank toward a position eccentric with respect to a central axis of the cylindrical inner peripheral surface to store the cleaning liquid within the storage tank and configured to form a vortex flow of the cleaning liquid revolving within the storage tank. The overflow discharging portion is configured to discharge the cleaning liquid that overflows the storage tank.

The present invention relates to a compact container having a contamination-preventing cooling plate and, more specifically, to a compact container having a contamination-preventing cooling plate, comprising: a discharge means, inside the compact container, for discharging cosmetics; a discharge plate having a discharge hole and a coupling groove formed in the center thereof; and the cooling plate, which is coupled to the upper part of the discharge plate, has an outlet formed in the center thereof, and is made from a metal material, wherein a contamination guard plate is coupled to the coupling groove of the discharge plate so as to block most of the outlet of the cooling plate while leaving only a discharge gap, and thus, when a user uses the cosmetics while pressing the cooling plate with a puff, the contamination guard plate blocks the outlet of the cooling plate, excluding the discharge gap, so as to prevent bacteria or contaminants from entering the outlet from the puff, and the cooling plate, which is made from the metal material, lowers the temperature of the discharged cosmetics so as to provide a cooling effect when the cosmetics are applied to the skin such that user satisfaction improves. The present invention provides a compact container having a contamination-preventing cooling plate, comprising: a discharge means (40) for discharging cosmetics; a discharge plate (50) coupled to a discharge means (40), and having a discharge hole (52) and a coupling groove (54) formed in the center thereof; and a cooling plate (60), which is coupled to the discharge plate (50), has an outlet (62) formed in the center thereof, and is made from a metal material, wherein a contamination guard plate (70) is coupled to the coupling groove (54) of the discharge plate (50) such that a discharge gap (72) is formed between the contamination guard plate (70) and the cooling plate (60).

The present application relates to a cartridge paint refilling device. More specifically the subject matter of the application relates to cleaning the paint adhered to the feed tube of the cartridge and prevent reduction of the painting quality and undesirable rotation caused by the paint residue. An annular flow path extending from a base end side towards a front end side in the insertion direction is disposed between the feed tube of the cartridge and the feed tube insertion hole of the cartridge supporting member. The cartridge supporting member is provided with a feed tube cleaning pipeline whose upstream side is connected with the circulation pipeline disposed at the cartridge supporting member and whose downstream side becomes a cleaning fluid discharge port and pens at the base end side of the annular flow path; and a pipeline witching valve which blocks communication between the circulation pipeline and the feed tube cleaning pipeline when the paint and the cleaning fluid are supplied to the paint chamber of the cartridge, and enables communication between the circulation pipeline and the feed tube cleaning pipeline when the cleaning fluid is supplied to the annular flow path.

A process and system for cleaning a high pressure separator vessel in a polymerization reactor without removing the top cover and its associated bolts by providing a cleaning hole in a fluid fitting above and adjacent to the top cover, through which a cord or cable is fed and affixed to a rotatable cleaning nozzle. The cleaning nozzle is gradually raised, lowered and rotated to direct a high pressure liquid onto the interior walls of the vessel to remove accumulated waste material.

According to an embodiment of the invention, a coating head of a mist coating film formation apparatus including a main body is provided. The main body includes a top plate in which a supply port capable of supplying one of a cleaning liquid or a mist of a source material solution is provided, a bottom plate provided below the top plate in a vertical direction, and a sidewall provided between the top plate and the bottom plate; and the sidewall includes an upper end and a lower end connected respectively to the top plate and the bottom plate and forms an interior space with the top plate and the bottom plate. The sidewall includes a slit spraying the mist externally from the interior space, and a recovery port capable of recovering the supplied cleaning liquid or a mist coalescing in the interior space. The bottom plate includes a slope having a height becoming lower from an inner perimeter of the sidewall toward the recovery port.
