The application discloses a multi-nozzle coal water slurry supercritical water gasification reactor, which adopts a multi-layer structure and is internally provided with a sleeve; a cavity surrounded by the sleeve is a hydrogen-oxygen heat release area; an annular area between the sleeve and an outer shell is a gasification area; and a slag discharge area is arranged at the bottom of the reactor; an oxidant inlet pipe and a reaction product outlet are arranged at the top of the hydrogen-oxygen heat release area; a plurality of rows of nozzles are arranged on the longitudinal direction of the gasification area shell; and tangential supercritical water inlets are additionally arranged on the gasification area shell; and spiral guide vanes can be additionally arranged on the outer wall of the sleeve and the inner wall of the shell to strengthen flow field regulation. The high-speed tangential injection of supercritical water and the spiral guide vanes can make coal particles and supercritical water form a rotating flow in the gasification area, strengthen heat and mass transfer and mixing processes, and accelerate the reaction rate. Meanwhile, hydrogen generated after the supercritical water gasification of coal flows upward along the fluid after turning back, reacts with the oxidant in the hydrogen-oxygen heat release area, and releases heat, thereby providing the required heat for the supercritical water gasification of coal, and realizing efficient conversion of coal.

The invention discloses a water-jet-guided laser head and a water-jet-guided laser processing device, relates to the technical field of laser processing, and aims to solve the problems that an existing water-jet-guided laser head cannot cool a lens and cannot dry the interior of the existing water-jet-guided laser head. According to the water guide laser head, the vortex separation structure is arranged on the shell, so that input high-pressure gas can be separated into cold airflow and hot airflow; wherein cold air flow can flow into the mirror cavity from the cold air outlet of the vortex separation channel through the cooling channel, is directly contacted with the lens assembly, exchanges heat with the lens assembly and then is discharged from the cold air discharge hole, so that the temperature of the lens is effectively reduced, and the mirror cavity is dried and cleaned; the hot air flow can flow into the fit clearance of the drying chamber and the nozzle from the hot air outlet of the vortex separation channel to dry the interior of the water guide laser head, and is discharged through the hot air discharge structure while taking away internal moisture and impurities to form positive pressure air flow blown outwards, so that the interior of the water guide laser head is further ensured to be dry and clean.

This invention discloses an improved high-efficiency ice maker, comprising a shell, an upper end cover, a lower end cover, a rotating shaft, and a spiral scraper. The shell includes an outer cylinder, a middle cylinder, and an inner cylinder. A spiral guide plate is installed inside the refrigeration chamber, and multiple flow-tampering components are also installed within the refrigeration chamber. The key feature is that the flow-tampering components include an outer ring cylinder, an inner ring cylinder, a swirling ring, a rotating rod, spiral blades, and a flow-tampering tube. The inner and outer ring cylinders are connected via a swirling ring. A rotating rod is located at the center of the inner ring cylinder, and spiral blades are connected to the outer circumference of the rotating rod. A flow-tampering tube is located at the downstream end of the inner ring cylinder, and the flow-tampering tube is connected to a first connecting seat via a support rod. Both ends of the rotating rod are rotatably connected to the first and second connecting seats, respectively. This invention enables better mixing of the refrigerant, allowing for sufficient heat exchange between the refrigerant and the refrigeration chamber and its walls, thereby improving the production efficiency of slush / ice slurry / ice residue and enhancing the overall performance of the ice maker.

This utility model discloses a urea hydrolysis mixing chamber, relating to the field of automotive engine exhaust gas purification technology, including a housing; a top cover is connected to the top of the housing, and a disassembly mechanism is provided between the housing and the top cover. In this utility model, urea solution is atomized by a spray system and injected into the mixing chamber; multiple swirl plates generate turbulence, causing the urea droplets to initially mix with the high-temperature exhaust gas, extending the residence time and promoting droplet evaporation. The high-temperature exhaust gas enters from the high-temperature exhaust gas inlet at the bottom and flows upward through the delivery pipe. The exhaust gas forms a high-speed airflow through the pores on the guide plate, impacting the urea droplets and accelerating the pyrolysis reaction. The obliquely designed spiral blades further enhance the airflow swirling effect, ensuring full contact between the urea droplets and the exhaust gas. The microchannels on the evaporation plate significantly increase the specific surface area. By utilizing the swirl plates to generate turbulence, it is possible to ensure that the urea droplets and the high-temperature exhaust gas mix rapidly and thoroughly, thereby improving reaction efficiency.
