The invention relates to a composition of a urea reducing agent capable of improving atomization effect, which is composed of a component A, a component B, a component C, a component D and a component E; and is characterized in that the component A is urea which accounts for 25 parts-30 parts of a mixture, the component B is low molecular alcohols which account for 15 parts-35 parts of the mixture, the component C is an industrial kathan anticorrosion bactericide which accounts for 0.002 parts-0.005 parts of the mixture, the component D is industrial fluorescent dye which accounts for 0.001 parts-0.003 parts of the mixture, and the component E is water which accounts for 34.997 parts-59.992 parts of the mixture. The composition is taken as a vehicle reducing agent which meets the 4 level and more emission standard of the state. Compared with the traditional urea reducing agent, the surface tension of the composition of urea reducing agent is reduced by more than 50%, the spray atomization performance of vehicles can be improved, NOX removal reaction efficiency can be improved, the escape amount of NH3 can be minimized, the process for removing PM can be benefited, the cost is low and the no pollution is generated.

The invention relates to an atomizing and spraying device of a conical air flow field. The device is characterized in that a dustproof end cap is fixedly arranged on a casing to form a conical annular seam, a generating line of the conical annular seam and an axis form an included angle, the conical annular seam forms a spraying angle of the conical air flow field, the center of the dustproof end cap is provided with a water pipe inlet, the periphery of the center of the dustproof end cap is uniformly provided with eight ventilation holes in the circumferential direction, the connecting part of the dustproof end cap and the casing is provided with a compressed air inlet which is communicated with compressed air, and the pipe diameter of the casing is gradually increased from interior to exterior to form a horn-shaped passage structure. The atomizing and spraying device has the advantages that a mechanical rotary part and a power source are not arranged, so the safe production of coal mines is favorable, the spraying and atomizing effects are good, and the coverage range of water mist is large; the structure is simple, and the convenience in use is realized; and the noise is less, and the working is safe and reliable.

A composite heat transfer medium anti-corrosion coating and a preparation method thereof, including the following elements by weight percentage: Al: 3.0-7.5%, Cr: 20.0-23.0%, Ni: 23.0-26.0%, Co: 23.0-26.0% , Re: 0.5‑2.0%, Si: 0.5‑1.5% and Fe: 22.0‑25.0%. The main components of the coating are Al, Cr, Ni, Co, Fe five elements, these five elements can form Al in the present invention x The CoCrFeNi high-entropy alloy has good mechanical properties, and at the same time, these five elements all have excellent corrosion resistance and high temperature resistance; the bonding force between the coating prepared by the invention and the N80 carbon steel base material reaches more than 145 MPa.

The invention discloses a nozzle of an interrupted clear water extinguisher, which comprises a nozzle shell, wherein the nozzle shell is internally and fixedly provided with an interrupted flow guide seat, and the flow guide seat is provided with at least one flow guide column installing hole; cup bottoms of the flow guide column installing holes with cup-shaped structures are provided with a plurality of water spraying holes, and the eccentricities e between the flow guide column installing holes and the water spraying holes are equal to 0.1-3mm; and the flow guide column installing holes are internally and movably provided with a plurality of helical type flow guide columns, the surface of the each helical type flow guide column is provided with at least one helical flow guide groove, and the helical angles alpha of the helical flow guide grooves are equal to 30-60 degrees; and the distance from the bottom of each helical flow guide groove to the axial lead of each helical type flowguide column is less than the semidiameter of each water spraying hole. The ratio of the diameter D of each flow guide column installing hole to the diameter d of each water spraying hole D / r is equal to 2-3. The nozzle not only can extinguish a combustion source with electricity by the clean water, but also is reasonable and simple in structure, safe and convenient in use, and widely used for various fire-fighting lances.

The invention discloses a screw type atomization-spraying dust precipitating device applicable to atomization of water or water-air and other media with relatively low viscosity. An upper end cover of the device adopts a cylindrical structure, an external thread is arranged at the upper end part, an air inlet is horizontally formed in the middle of the upper end cover and adopts a bolt hole structure, a screw valve is arranged in the center of the upper end cover, and the screw valve and the center of the upper end cover are located on the same axis; a taper hole is formed in the center inside the screw valve and connected with the air inlet, through holes are formed in positions equally spaced from the periphery of the taper hole and are water inlets, a plurality of screw grooves are arranged on the outer edge of the screw valve and have rectangular sections, and the length-width ratio of the rectangles is gradually increased; the upper end cover and an oscillation cavity at the lower end are connected through bolts; the lower end of the oscillation cavity is connected with a connecting piece through threads, the connecting piece adopts a U-shaped groove structure, a bulge is arranged in the middle of the U-shaped groove, and a horn-shaped spray head is arranged in the center of the bulge. The device is simple in structure, easy to control and adjust, good in atomization effect, high in practicability, safe and reliable.
