Description
Technical field
The present invention relates to a kind of converter gas evaporation cooling washing system, belongs to prevention and control of air pollution and flue gas cooling and dedusting technical field.
Background technology
Environmental issue becomes a key factor of restriction China steel and iron industry sustained and coordinated development.Enforcement from 1 day October in 2012《Steel and iron industry air dye thing discharge mark Huaihe River》(GB28664-2012), stricter air dye thing emission control requirement and limit value is defined to steel-making enterprise.On 2 27th, 2013, country determines that the industries such as iron and steel, cement will start to execute the special emission limit of atmosphere pollution in different periods again, on January 1st, 2015 starts, no matter newly-built or existing enterprise, its concentration of emission must all reach below 50mg/m3, on 2 27th, 2013, country determined that the industries such as iron and steel, cement start to execute the special emission limit of atmosphere pollution in different periods；According to the trend that Environmental quality requirement is more and more strict, more city and enterprise are scheduled on below 30mg/Nm3 enterprise's internal control smoke dust discharge concentration at present.In China's history, most tight new environmental law had begun to implement from January 1st, 2015, and followed by, various places will be put into effect successively according to a variety of refinement policies that new environmental law is worked out.
Current environmental protection pollution treatment is in the critical period for solving the problems, such as the old and new, and used as the pneumatic steelmaking link of one of the important pollution sources of iron and steel enterprise, flue gas particles discharge of converter is the dye thing thing exhausting control source that especially lists in national standard.How enterprise selects the handling process that be suitable for according to actual conditions, realizes the efficiency upgrading of converter gas purification and recovery process technology, it has also become the focus of iron and steel enterprise's modern converter steel-making energy-saving and emission-reduction and focus.
Converter generates substantial amounts of high-temperature gas in oxygen blast smelting process, converter gas have that high temperature, flow are big, dustiness is more, toxic and explosive the features such as, during using unburned method gas recovery, in furnace gas, the main oxides CO content of carbon averagely accounts for 70%.When blowing simultaneously, as under high temperature action, a variety of causes such as acute row stirring, the explosion of CO bubbles and splash of the evaporation of iron, air-flow produces substantial amounts of stove dirt, its total amount is about the 1%-2% of metal charge, about 10%--20Kg/t steel, stove dirt is mainly the dust such as FeO, Fe2O3, CaO, SiO2, and dustiness is about 80 150g/Nm3.It is more than 10 μm that its particle diameter is most of when furnace gas is unburned, and then most of after furnace gas burning is less than 1 μm, and relative trapping difficulty is big.
Converter current (flue gas) gas purification and recovery system gas cleaning mode mainly have a form such as wet OG methods, semidry method (dry and wet is combined) and dry method LT method entirely, and the converter gas purification and recovery process more than 70% being currently running is i.e. usual wet method OG of wet-scrubbing equipment with Japanese OG methods technique as representative.
The new OG wet method systems resistance for generally splitting is damaged still high:Actually used middle blower press generally reaches 22KPa--24 KPa；System water amount is big, and supporting water treatment facilities are huge；Maintenance of equipment amount is big, and operating cost is high.
Generally the dehydrator of OG wet method systems is same circulating water treatment water system with the washing of tower text and process water.In actual moving process, reuse recirculated water suspension mass concentration is required usually beyond 150mg/L, in many cases even ＞ 250mg/L.
Converter current steel making working procedure is toward firmly as the presence of converter smelting operating mode is re-blow, fire door slagging scorification, iron ore, furnace charge, cooling agent etc. enter stove furnace charge relative mistake, enter system dust contained flue gas concentration high, preposition cooling cleaning dust grade dust-collection efficiency is low, so as to the total efficiency of dust collection of dust pelletizing system is difficult to improve.
During traditional cooling and dedusting, scale formation on long-time tube wall, is susceptible to, resistance damage is higher, causes service life low, and cooling dust removing effects are poor.
Content of the invention
