Apparatus for cleaning a surface with a liquid jet, the apparatus having: a main housing; a primary fluid conduit having a longitudinal axis and two ends, a fluid-intake end and a fluid-exit end; a gear assembly configured to engage the primary fluid conduit and rotate the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a motor mounted to the main housing and configured to engage the gear assembly and thereby rotate the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a bifurcated head connected to the primary-fluid-conduit fluid-exit end, the bifurcated head having at least one fluid conduit; a hydraulic cylinder; a hydraulic-cylinder rod having a first end and a second end; a pivot pin having a longitudinal axis and the pivot pin being attached to the bifurcated head; a nozzle connected pivotally to the pivot pin; the hydraulic cylinder mounted to the main housing and configured to move the hydraulic-cylinder rod along a linear path by exerting a unidirectional force upon the first end of the hydraulic-cylinder rod; the hydraulic-cylinder rod positioned within the fluid conduit and the second end of the hydraulic-cylinder rod pivotally connected to the nozzle; and the nozzle configured to pivot about the pivot-pin longitudinal axis as the hydraulic-cylinder rod moves along the linear path.

The present invention discloses a coal-to-acetylene plasma reactor having coking inhibition and online decoking functions, comprising a vertically arranged cathode rod, an anode and a circulating cooling water jacket arranged outside the anode, the anode includes from top to bottom an anode of the electric arc operation section for cooperating with the cathode rod to generate an electric arc, and an anode of the reaction section located below the electric arc, the anode is grounded, the inner diameter of the anode of the reaction section is 1.2 to 10 times the inner diameter of the anode of the electric arc operation section, and the junction of the anode of the reaction section and the anode of the electric arc operation section is circumferentially provided with a decoking nozzle that can spray a decoking medium toward the anode of the reaction section. The present invention uses the method of changing the inner diameter of the reactor and setting nozzles for diaphragm protection, fundamentally suppressing or even eliminating the coking phenomenon during the operation of the reactor, no need to set the decoking cycle, and realizing the continuous cracking operation of the reactor.

The present invention relates generally to a method to determine one or more properties in a water storage facility and/or a water treatment facility. In one embodiment, the present invention relates to a method to determine one or more chemical and/or physical properties in a water storage facility vessel and/or a water treatment facility vessel and then use such one or more chemical and/or physical properties to determine where, if need be, any sand or other sediment needs to be removed from any such water storage facility vessels and/or a water treatment facility vessels.

A complete fuel tank maintenance and cleaning system. This apparatus and method are capable of effectively cleaning an underground or aboveground storage tank by implementing a multi-stage filtration and removal system, and effectively removing contaminants from tank surfaces by using the product or alternative as a streamed cleaning agent within the storage tank.
