The subject of the invention is a method of hydraulic transport of power-industry slags and other solid waste materials from power plants, thermal-electric power stations and heating plants to the point of their receiving or storage, whereby transport is performedby forcing slags and other waste materials through pipelines under presser produced by pumps.
The known and presently applied methods of transporting power-industry slags and other solid waste materials from power plants, thermal-electric power stations and heating plants consist in utilization of belt conveyors, road or rail transport, or hydraulic transport in pipelines. They are described in technical literature, e.g. in publications by Risse F. "Betriebserfahrungen mit ver- schiedenen Entaschungsanlagen", . Mitteilungen VGB, 1966, pp. 22-28; Risse F., "Hydraulische Entaschung", Mitteilungen VGB, 1970, pp. 386-394; Buchmuller H.A. "Betriebssiche- rer Feuerraum"- Entaschung mit Braunkohle - Dampferzeugern Energie, Mai 1976. In case of hydraulic transport of slags and waste materials the installation is usually designed so that falling out dry fly-ashes are washed down in washing apparatuses of various types, this causes that density of the mixture of water with ash is low because of very large water excesses. After adding slags and other waste materials to said mixture they are transported by pipelines, and the flow of the mixture is forced by pumps.
Percentages by weight of slag in the mixture is inconsiderable in practice and usually does not exceed ten percent. Flow velocities of the mixture in pipelines must be selected so that slag particles do not settle on the bottom of the pipeline. The said method of hydraulic transporting of slags and other solid waste materials is characterized by high energy-consumption and a considerable amount of water per mass unit of transported slags and waste materials.
The object of the invention is to design a new method of transporting power-industry slags and other solid waste materials from power plants, thermal-electric power stations and heating plants, which is characterized by essential advantages in comparision with those hitherto discussed and applied.
The task of the invention is to decrease energy consumption and to reduce water consumption per mass of unit of slags and waste materials being transported hydraulically. The said task has been attained in such a manner that power-industry slags and other solid waste materials are transported in pipelines, and the carrying agent being applied is a heavy liquid which is a dense suspension of dry fly-ashes in water, preferably of a volumetric composition in proportion of from one to six parts of water per one part of dry fly-ashes. To this heavy liquid power-industry slags and other solid waste materials must be added at a volumetric proportion of preferably up to 0.2 parts of slags and waste materials per one part of a heavy liguid. This mixture of slags and waste materials with a heavy liquid flows through pipelines, the flow being forced by a pump.
A system of devices for carrying out the method of hydraulic transport of power-industry slags and other solid waste materials from power plants, thermal-electric power stations and heating plants must include a separate set of devices, wherein a heavy liquid is produced, which is a suspension of dry fly-ashes in water, and a main mixer wherein proportioned power-industry slags and other solid waste materials are mixed with the heavy liquid and maintained in a suspension state, as well as a pump to which the mixture of slags and waste materials in the heavy liquid flows by gravitation, and which causes forcing said mixture through pipelines to the place of destination.
An advance of the method of transporting power-industry slags and other solid waste materials according to the invention consists in that off-taking of ashes, slags and other waste materials takes place simultaneously with considerably reduced energy consumption and considerably reduced water consumption per mass unit of the solid phase. Since slags and other solid waste materials are transported through pipelines in a stream of a heavy liquid of a density being several ten percent higher than the density of water, it is possible to apply reduced flow velocities of the liquid without the effect that solid body grains settle on the bottom of the pipeline.
The application of the invention renders it possible to reduce costs resulting from electric energy consumption and reduction of water consumption.
The method of transporting power-industry slags and other solid waste materials from power plants, thermal-electric power stations and heating plants, according to the invention, can be applied in power plants, thermal-electric power stations and heating plants whose pulverized fuel boilers are fired with hard or brown coal.
