A fog dispersing and water collecting device for a wet cooling tower relates to an assistant facility for the wet cooling tower. The device is arranged at the lower end of a cooling tower air duct and at a position below a fan and above an original water collector of the cooling tower; a separating plate is arranged in a water collecting and distributing chamber of the device and divides the chamber into a water collecting chamber and a water distributing chamber; a water feeding pipe is connected with the water collecting chamber which is connected to one end of a condensing water pipe; the other end of the condensing water pipe is connected with the upper part of a water returning chamber; the lower part of the water returning chamber is connected with one end of the condensing water pipe again; and the other end of the condensing water pipe returns to be connected with the water distributing chamber of the water collecting and distributing chamber, so that a closed circulating structure is formed; a spraying pipe is connected to the lower end of the water distributing chamber; the condensing water pipe is integrally attached to a concave-convex radiating sheet; positioning through pipes are arranged at the upper end and the lower end of the concave-convex radiating sheet; a water resisting plate is arranged on the convex surface of the inner side of the concave-convex radiating sheet; and the upper end of the water feeding pipe is connected with the water collecting and distributing chamber while the lower end of the water feeding pipe is connected with a pressurizing water pump, and then the water feeding pipe is connected with a mixing water tank, so that the fog dispersing and water collecting device is formed. According to the fog dispersing and water collecting device, saturated wet and hot fog is condensed into water, so that the water is prevented from being evaporated, the water source is saved, and the pollution to the environment is avoided.

The invention relates to a high-temperature mineral powder cooling device belonging to the technical field of ferrous metallurgy. The high-temperature mineral powder cooling device comprises a volute body and a cooling center cylinder, wherein the volute body is arranged at the upper end of the cooling center cylinder, the volute body comprises a volute hole and a center shell, the center shell of the volute body is of a cylindrical structure with an opening in the lower end, a feeding pipe is arranged at the center of the top end of the volute body, the volute hole of the volute body is an air outlet, the cooling center cylinder is of a cylindrical structure with a through hole in the center, a cooling spiral water pipe is arranged in the through hole in the center of the cooling center cylinder, the discharging end of the feeding pipe is positioned above the cooling spiral water pipe, the upper end of the cooling spiral water pipe is communicated with a cooling water outlet by the cylinder wall of the cooling center cylinder, the lower end of the cooling spiral water pipe is communicated with a cooling water inlet through the cylinder wall of the cooling center cylinder, an air inlet is formed in the cylinder wall of the lower end of the cooling center cylinder, the opening in the lower end of the cooling center cylinder is communicated with a large opening of a conical cylinder positioned below the cooling center cylinder, and a small hole of the conical cylinder is a discharging hole.

A lubricating oil for high-temperature-resistant powder metallurgy oil-impregnated bearings, prepared from the following raw materials in parts by weight: 25-45 parts of trimethylolpropane ester, 55-75 parts of trimellitate, polymethacrylate 2-10 parts, 1-5 parts of diisooctyl diphenylamine, 1-5 parts of high molecular weight phenol, 0.1-1 part of benzotriazole, 0.1-1 part of triphenyl phosphorothioate and 0.005 parts of methyl silicone oil ‑0.02 parts. The lubricating oil of the present invention can carry out continuous and stable lubricating operation of oil-impregnated bearings at a temperature of 200°C or above. And the lubricating oil is not easy to change color after long-term use at high temperature, and there will be no oxidation and coking. The finished lubricating oil has a high flash point and low evaporation loss. After being used, it can significantly prolong the service life of the equipment and reduce its maintenance rate.
