The present disclosure provides a reactor cleaning apparatus including: a fixing part having a partial region inserted into a hole formed in an upper portion of a reactor to be coupled to the reactor and fixing a pipe; the pipe inserted into a hole formed in the fixing part, protruding downward from the fixing part, and having a length adjustable in a vertical direction; a spray nozzle provided at a lower end of the pipe; and a screener provided on a lower side surface of the pipe, and a reactor cleaning method using the same.

A water washing method and system for a crude oil tank. The water washing method includes inputting washing water into the crude oil tank; injecting high-pressure water to the lower portions of the crude oil tank such that the sludge mixes with the washing water; and discharging mixture water in which the sludge is mixed with the washing water from the crude oil tank.

A cavity cleaning and coating system for safely and efficiently cleaning and coating the interior of a cavity without requiring entry of any workers. The cavity cleaning and coating system generally includes a mount which is coupled with a movable arm of a vehicle. The mount includes an inner plate, which is coupled to the arm, and an outer plate. A shaft is coupled to the outer plate. The mount is adjustable independently of the arm of the vehicle, including outwardly, inwardly, and rotatably. A spray head is connected to the shaft. The spray head is rotatable and includes a dispenser for dispensing fluids. The vehicle is positioned near a cavity to be treated. The mount is adjusted for optimal positioning of the spray head. The spray head is lowered into the cavity to dispense a cleaning fluid and, after the cleaning fluid has dried, a coating fluid.

The invention relates to a method for the time control of an automated cleaning process in a tank container, wherein during the cleaning process cleaning liquid is sprayed onto the inner wall of the tank container by means of a spray head. According to the invention the following method steps are provided: detecting the heat removal of a heating element disposed in the flow-off area of the cleaning liquid; continuous determination of the state value of the cleaning liquid with regard to the two variables degree of contamination and spray rate by means of the heat removal; comparing the state value of the cleaning liquid in a quasi-stationary state with a target state value; and terminating the cleaning process when the current state value differs by less than a default value from a target state value.

A cleaning water feeding tool having a pipe structure to feed cleaning water to a water sprinkling cleaning device which has both end portions rotatably supported by a rotary base laid between a pair of rotary support parts disposed opposite to each other on a basket-shaped base, and includes the rotary head rotates with respect to the rotary base, and the rotary base rotates with respect to the basket-shaped base, including a horizontal portion that has a tip end portion connected to the cleaning water supply port and extends approximately horizontally in a state where a rotary shaft of the rotary base is disposed approximately horizontally, a straight portion that extends upward from the horizontal portion; and a hard material that configures or covers at least a portion receiving the cleaning water jetted from the water jet part of the straight portion.

A cylinder head cleaning method capable of cleaning a cylinder head with an enhanced foreign matter removing rate. The method is used to clean a cylinder head (1) having therein a water jacket (15) including a narrow space portion (Z) having a narrow flow path and a large space (Y) having a flow path wider than the narrow space portion (Z), and the cylinder head (1) further having holes (12A-12R, 13, 14, 16A-16C) communicating with the water jacket (15). Cleaning nozzles (28A, 28C) are inserted into the water jacket (15) from the holes (16A, 16C) selected from the holes (12A-12R, 13, 14, 16A-16C), clearing liquid is ejected from the cleaning nozzles (28A, 28C) toward the narrow space portion (Z), and the cleaning liquid flowing from the narrow space portion (Z) to the large space (Y) is discharged to the outside of the cylinder head (1) from the hole (16B) communicating with the space (Y).

A self-cleaning sink has an undermounted bowl connected to a countertop. The perimeter of an internal bowl portion extends about a perimeter of a sink access permitting access through the countertop into the bowl and a base of the countertop spaces the internal bowl portion from the sink access perimeter. The base has at least one port in communication with a cross passage which selectively directs water into the bowl in a self-cleaning.

A hydrocarbon waste-gas recycling method having the steps of: transporting a hydrocarbon waste-gas composition, which is generated during a hydrocarbon storage-tank cleaning process, from a storage tank that is being cleaned to a fuel-gas blend controller; blending the hydrocarbon waste-gas composition with a second hydrocarbon gas-phase composition to thereby create a third gas-phase composition; and using the third gas-phase composition to fuel a combustion engine.

An apparatus for raising and lowering a cutting tool within a decoking drum, a decoking system and a method of raising and lowering a decoking system cutting tool. Instead of using metallic ropes, chains, or a self-propelled gear-based approach, non-metallic belts are secured at respective ends to a crosshead and one or more counterweights to enable vertical movement of the crosshead that in turn permits vertical movement of the cutting tool throughout the height of the drum. A motorized pulley system controls the movement of the belt, and preferably avoids having the motor be carried by the crosshead. The belts on each pulley are preferably arranged as cooperative sets so that within each set, both primary load belts and secondary load belts are present. Enhanced engagement between at least the primary load belts and the pulleys promotes greater load-bearing capability, while the secondary load belts are sufficiently strong to ensure positional stability of the crosshead and decoking tool upon damage to or failure of one or more of the primary load belts.
