Technical field
The present invention relates to sintering waste heat and utilize field, specifically, be that high temperature sintering ore deposit can be taken out by one from sintering machine, and carry out fragmentation, screening, transhipment and insulation, enter high temperature sintering ore deposit transporter and the technique of stove formula cooling system.
Background technology
Steel and iron industry is AND ENERGY RESOURCES CONSUMPTION IN CHINA rich and influential family, accounts for 15% of national total energy consumption, in steel manufacture process, and the energy consumption of sintering circuit occupies the second, and in SINTERING PRODUCTION, heat sinter sensible heat accounts for more than 40% of overall heat consumption, and sintered, energy saving is very important.High efficiente callback utilizes sintering mine sensible heat to be the effective way improving steel and iron industry efficiency.
The cooling of Current Domestic sintering deposit is main adopt ring cold/be with cold technique, have that fault rate is high, maintenance is frequent and difficulty large, run that power consumption is high, leak out a little many, inleakage large (more than 30%), the key difficult problem such as cooling effect is poor, the rate of return mine is high, while also constrain sintering machine waste heat high efficiente callback utilization.That sintering deposit stove formula process for cooling thoroughly can solve ring is cold/be with cold technique Problems existing, there is raising sintering deposit cooling quality, raising waste heat flue gas quality, the cogeneration ability that improves, reduction cooling system power consumption, raising afterheat generating system adaptability and reduce the advantages such as pollutant emission such as flue dust, and significantly can improve cogeneration amount more than 50%, reduction system from electricity consumption 25%, raising sintering machine year running rate 1-2%, be a kind of revolutionary technology, subversiveness product, there is vast potential for future development.
The prerequisite and the key that realize sintering deposit stove formula process for cooling to provide a kind of high temperature sintering ore deposit transporter and technique reliably, high temperature sintering ore deposit can be taken out from sintering machine, and after carrying out fragmentation, screening, transhipment and insulation, enter stove formula cooling system.Because stove formula cooling sintering deposit cogeneration technology is a kind of brand new technical, the research for high temperature sintering ore deposit transporter and technique is also less.From the high temperature sintering ore deposit that sintering machine takes out before entering stove formula cooling system, if do not have sintering deposit transporter reasonable in design and technique, the thermal loss of sintering deposit can be made more, utilization rate of waste heat reduces.Therefore, develop a kind of do not affect sintering machine produce main technique, there is higher reliability of technology, prevent sintering deposit heat loss and reduce the high temperature sintering ore deposit transporter of construction costs and technique significant.
Summary of the invention
The object of the invention is for solving the problem, not affecting for sintering deposit stove formula process for cooling provides a kind of the high temperature sintering ore deposit transporter and technique that sintering machine is produced, reliable, sintering deposit granule size is suitable, thermal loss is less.
To achieve these goals, the technical solution used in the present invention is: high temperature sintering ore deposit transporter, comprise with lower device: single roll crusher, flap valve, high-temperature vibrating sieve and conveyer, there is flap valve the below of described single roll crusher, the junction of the bottom of flap valve is arranged at ring cold/band cooling system feeding chute and stove formula cooling system feeding chute, flap valve can cold at ring/band cooling system feeding chute and stove formula cooling system feeding chute between switch, the diapire of stove formula cooling system feeding chute is provided with high-temperature vibrating sieve; The outlet of stove formula cooling system feeding chute is connected with one end of conveyer, and the other end of conveyer connects the fire door of cool furnace, and the top of conveyer is provided with stay-warm case.
The sieve diameter scope of described high-temperature vibrating sieve is 5-10mm.
Described conveyer can adopt chain scraper conveyor or bucket chain conveyor.
The inclination angle of described conveyer is 0-30 °.
The cross section of described stay-warm case is arc.
High temperature sintering ore deposit transhipment technique, comprises the following steps: the sintering deposit that sintering machine sinters into is crushed to after below 150mm through single roll crusher, falls to flap valve, by flap valve carry out feeding control enter stove formula cooling system or ring cold/band cooling system; When stove formula cooling system normally runs, sintering deposit enters stove formula cooling system feeding chute by flap valve, by gravity fall on high temperature vibratory sieve, after the fine ore of granularity <5mm screens out by high-temperature vibrating sieve, the sintering deposit that granularity is qualified is transported to cool furnace by conveyer, in transport process, by the stay-warm case above conveyer, sintering deposit is incubated; When stove formula cooling system breaks down, sintering deposit by ring cold/band cooling system feeding chute enters ring cold/band cooling system.
The beneficial effect that the present invention brings is: 1. sintering deposit is broken through single roll crusher, and high temperature sintering ore deposit larger for granularity is crushed to below 150mm, and the sintering deposit preventing granularity excessive enters cool furnace, cannot fully cool; 2. sintering deposit flap valve can cold at former ring/band cooling system and stove formula cooling system between switch flexibly, improve the running rate of sintering machine; 3. sintering deposit is through the screening of high-temperature vibrating sieve, prevents the fine ore being less than 5mm from entering cool furnace and causes Gas-solid flow drag losses to increase; 4. transporter adopts high inclination angle conveyer, and conveyer adopts heat resistant and wear resistant material, and reliability is high, construction costs is low; 5. adopt arc stay-warm case to be incubated in transport process, its inner space is reduced as far as possible, effectively weaken the decay of high temperature sintering ore deposit heat radiation at upper space, further reduce sintering deposit thermal loss, improve utilization rate of waste heat; 6. sintering deposit realizes comparatively long-distance sand transport by conveyer, solves a difficult problem for sintered production line site layout project complexity.
