Abstract
The invention discloses a hot flue gas drying device for a silo, which comprises a vertical column frame and a flue gas main pipe, wherein a main pipe support is arranged on the vertical column frame, a tile-shaped support is arranged on the top surface of the main pipe support, the flue gas main pipe is horizontally placed on the tile-shaped support, two drying branch pipes are connected to the flue gas main pipe side by side at intervals, the drying branch pipes respectively extend into the silo, the cross sections of the drying branch pipes are equilateral triangles, T-shaped supports are arranged in the drying branch pipes, two groups of rectangular exhaust hole arrays are arranged on the horizontal bottom surfaces of the drying branch pipes side by side along the axial direction of the branch pipes, and wear-resistant lining plates are respectively and fixedly connected to the top surfaces of the two sides of the drying branch pipes through sunk. The combustion waste gas of the heating furnace is introduced into the storage bin to bake the raw materials. This hot flue gas of feed bin dries by fire material device, simple manufacture, convenient operation, the rate of operation is high, and the effect is obvious.
Description
Technical Field
The invention relates to a hot flue gas drying device for a material bin.
Background
In the existing raw material storage system for industrial production in China, materials with high water content are put into a bin to cause the wall of the bin to be hardened, the bin is not discharged, and lump coal with high water content is added into a metallurgical furnace to cause the increase of thermal explosion of the lump coal in the melting gasification metallurgical Europe and metallurgy furnace, the increase of dust content and tar content of output coal gas, the increase of oxygen demand of a gasification furnace, the decrease of temperature of a dome of the gasification furnace, the decrease of reduction potential of the output coal gas, the consumption of heat in a high temperature area and the increase of coal consumption (moisture content) and the serious interference to normal production of. In addition, the moisture is gasified to consume heat in a high-temperature area. Meanwhile, a large amount of pulverized coal is loaded into the gasification furnace or high-moisture lump coal is added into the gasification furnace to generate the charged pulverized coal through thermal cracking, so that the coke ratio and the fuel ratio are increased. If production is carried out in winter, raw materials in the stock bin and the foam bin are easy to freeze, so that the stock bin does not discharge materials. The charging of the furnace is influenced, the yield and indexes are reduced, and the cost is increased. Meanwhile, the stock bin does not discharge materials, the materials are poked manually, the workload and labor cost of workers are increased, the labor productivity is reduced, and the safety of personnel cannot be guaranteed during poking the materials.
Disclosure of Invention
The invention aims to provide a hot flue gas drying device for a material bin, which can achieve the purpose of drying moisture in raw materials by utilizing tail gas of a flue gas furnace through a draught fan and a flue gas pipeline.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a hot flue gas of feed bin dries by fire material device, includes stand frame and flue gas house steward, is setting up a house steward support on the stand frame, is setting up a tile shape support on the house steward support top surface, the flue gas house steward level place on the tile shape support, two are drying by fire the material branch pipe on the flue gas house steward side by side the interval connection, dry by fire in the material branch pipe stretches into the feed bin respectively, dry by fire the transversal equilateral triangle of personally submitting of material branch pipe, set up the T support in drying by fire the material branch pipe, dry by fire and set up two sets of rectangle exhaust hole arrays side by side along the branch pipe axial on the horizontal bottom surface of material branch pipe, dry by fire and pass through countersunk head.
The invention does not consume energy, introduces the combustion waste gas of the heating furnace, leads the waste gas of the combustion furnace into the storage bin through the induced draft fan, the flue gas pipeline and the drying branch pipe in the storage bin to bake the raw materials. This hot flue gas of feed bin dries by fire material device, simple manufacture, convenient operation, the rate of operation is high, and the effect is obvious. After the flue gas is introduced, the moisture in the raw materials is roasted, and the method is suitable for the requirement of the heat for drying materials (coke, ore, coal powder and lump coal). By using the heating device in the factory, the capacity of the metallurgical furnace is improved, the fuel ratio is reduced, and a space is provided for cost reduction of enterprises.
Drawings
The present invention will be described in further detail below with reference to the accompanying drawings.
FIG. 1 is a schematic front view of the present invention;
