Description
Technical field
The utility model relates to a kind of water cooling plant for top blow smelting stove exhaust-heat boiler inlet.
Background technology
The position being connected with waste heat boiler at top blow smelting stove, generally need to adopt water-cooled partition apparatus, when main cause is waste heat boiler maintenance, need cut off smelting furnace thermal source, water-cooled partition apparatus is set in addition and can solves expansion and the sealing problem that this position exists.At present, water-cooled partition apparatus generally adopts the water-cooling screen of the cooling coil structure of high temperature high voltage resistant, the boiler water that its inner loop water is HTHP, the water-cooling screen of this cooling coil structure manufactures very difficult, cost is high, and because the flue-gas temperature producing in smelting non-ferrous metal process is high, dustiness greatly, easy bonding, flue gas condition is severe, the water-cooling screen of cooling coil structure is easily subject to flue gas wearing and tearing and booster, have a strong impact on the safe operation of boiler, during replacing, need whole water-cooling screen to change, time-consuming, effort and the high waste of expense are large.
Summary of the invention
The purpose of this utility model is to provide a kind of Quick-attachable exhaust-heat boiler inlet water cooling plant, overcomes former water-cooled partition apparatus manufacture difficulty, dismantles inconvenient shortcoming.
A kind of Quick-attachable exhaust-heat boiler inlet water cooling plant, it is characterized in that: comprise four water-cooling screens, between water-cooling screen, with flange, connect, form water-cooled flue, fume side on described water-cooling screen steel plate is welded with bitch, and has built high-temperature flame-proof pouring material, and the recirculated cooling water of described water-cooling screen is connected with external refrigeration water system by metal hose, described water-cooling screen upper flange is connected with three-dimensional expansion regulating device, and described water-cooling screen bottom is connected with top blow smelting outlet of still.
A Quick-attachable exhaust-heat boiler inlet water cooling plant, is characterized in that: described water-cooling screen consists of semicanal and corrosion resistant plate welding, and four water-cooling screen flanges connect pad and adopt aluminosilicate fiberboard sealing.
A Quick-attachable exhaust-heat boiler inlet water cooling plant, is characterized in that: the passage length of each recirculated cooling water is no more than 12 meters.
A Quick-attachable exhaust-heat boiler inlet water cooling plant, is characterized in that: the overall channel resistance of described recirculated cooling water is not more than 6KPa.
A Quick-attachable exhaust-heat boiler inlet water cooling plant, is characterized in that: the import and export temperature rise of described recirculated cooling water is no more than 20 ℃.
The utility model has considered structure and the performance of exhaust-heat boiler inlet cooling device, in the situation that solving expansion and sealing, with the water-cooling structure of quick handling, substitute high-temperature high-pressure boiler water-bound, more be conducive to the safe operation of waste heat boiler, extended the explained hereafter cycle, when particularly waste heat boiler overhauls, can fast shut-off thermal source.Water cooling plant connects by flange, simple in structure, convenient disassembly; Build high strength at high temperature castable and can effectively avoid flue gas washing away and wearing and tearing water-cooling screen; Water-cooling structure and the waste heat boiler of low temperature divide open shop, import and export recirculated water and are connected with outside with metal hose, and connected mode is flexible, is not subject to the restriction of expanding.The utlity model has installation, convenient disassembly, advantages such as can repeatedly dismantling and reuse.
