Abstract
The utility model relates to a blast furnace gas alkali spraying and dechlorination device. The alkali spraying and dechlorination device comprises an alkali spraying tower; the lower end of the alkali spraying tower is provided with a cone bucket; the bottom of the cone bucket is provided with a drainage device; the side wall of the lower part of the alkali spraying tower is provided with a gas inlet; the top of the alkali spraying tower is provided with a gas outlet; the gas outlet is connected with a gas outlet pipeline; an alkali spraying device, a water spraying device and a packing dehydration device are sequentially arranged at intervals inside the alkali spraying tower and above the gas inlet from bottom to top; the gas inlet is connected with a gas inlet pipeline; and a mist spraying device is arranged in the gas inlet pipeline. Before entering the alkali spraying tower, coal gas is firstly subjected to water mist spraying humidification and temperature reduction in the gas inlet pipeline; moisture in the coal gas subjected to mist spraying is in a saturated mode; and the coal gas enters the alkali spraying tower from the gas inlet of the alkali spraying tower, gas flow firstly passes through the first layer of alkali spraying device to carry out alkali spraying neutralizing treatment from bottom to top, and the coal gas is humidified and cooled before, and thus, an acid medium in the coal gas can be rapidly and efficiently removed and a better acid-base neutralization effect is achieved.
Description
Technical field
The utility model is about a kind of blast-furnace gas alkali spraying dechlorination device, relates in particular to a kind of blast-furnace gas alkali spraying dechlorination device for the treatment of a large amount of acidic mediums (being mainly chlorion) in blast furnace gas after all dry-type dedusting.
Background technology
In recent years, domestic iron and steel enterprises blast furnace gas fully-dried type dust settling pocket technique has obtained large-scale popularization, owing to not considering after dry method dust removing of acidic medium in coal gas, can be after the certain hour a large amount of enrichments of acidic medium in coal gas, thereby cause the series of problems such as corrosion of low temperature blast furnace gas pipeline, pipeline compensator and subsequent technique equipment, shortened the work-ing life of blast furnace gas auxiliary facility.
Along with the application gradually of dry type coal gas dust removal technology, in coal gas, the etching problem of acidic medium also causes domestic colleague's attention gradually.Domestic-developed had gone out blast-furnace gas alkali spraying dechlorination device in recent years, but carried out because spray alkali dechlorination only concentrates in spray washing tower (for removing CO2), and the layout Shortcomings of spray gun simultaneously causes spraying washing tower (for removing CO2) equipment volume large, and injection flow rate is larger, and power consumption is large; In addition, the spray alkali neutralizing treatment effect of blast furnace gas also need to improve.
