Abstract
The utility model discloses a blast furnace gas gravity dust cleaner based on prior dust cleaner, which can improve dust cleaning efficiency. The utility model comprises a casing, a gas inlet tube, a pure gas outlet tube, a pure gas outlet, and an ash outlet valve. The upper and lower ends of the casing are rotary tables, the gas inlet tube is at the side wall of the upper rotary table, the pure gas outlet tube is at the top of the upper rotary table, the pure gas outlet is connected with the pure gas outlet tube, and the ash outlet valve is arranged at the bottom of the lower rotary table. The utility model is characterized in that a hopper-type baffle plate is arranged under the pure gas outlet. The utility model can improve the gas cyclone strength in the cleaner and the impact between dust and baffle plate to improve dust cleaning efficiency, reduce water consumption in following wet-type dust cleaning, reduce mud and sewage pollution, and reduce the maintenance and operation cost of filter-bag dust cleaner. The utility model has simple structure, easy production and installment, which can be used to clean dust of gas in new blast furnace and modify prior gas dust cleaner of old blast furnace.
Description
Technical field the utility model relates to a kind of gravitational precipitator, in particular for the gravitational precipitator of dedusting of blast furnace gas.
About 40～the 100g/m of blast furnace gas dustiness that background technology is discharged from the blast furnace furnace roof
3, need to make its dustiness drop to 5～10mg/m through dedusting
3Could be as the fuel of industrial burner.Dedusting of blast furnace gas system of iron and steel enterprise generally adopts two step dedustings at present, carries out thick dedusting with gravitational precipitator earlier, and big then blast furnace adopts wet scrubber, and medium and small blast furnace adopts bag dust collector to carry out half meticulous and meticulous dedusting.The wet scrubber water loss is big, the dirt mud of generation and sewage disposal difficulty.Bag dust collector system maintenance expense and working cost height.Therefore, for alleviating half meticulous and meticulous dust separating load, the water loss of minimizing wet dust removal and dirt mud and sewage reduce the maintenance and the working cost of bag dust collector to the pollution of environment, must improve the dust removal efficiency of gravitational precipitator.
The summary of the invention the purpose of this utility model provides the high blast furnace gas gravitational precipitator of a kind of efficiency of dust collection.
The gravitational precipitator that the utility model provides comprises: housing, raw gas are gone into pipe, purified gas goes out pipe, purified gas outlet, unloading valve.The housing upper and lower ends is a circular platform type, and raw gas is gone into pipe and is positioned at the round platform side-walls, and purified gas goes out the top that pipe is positioned at round platform, and the purified gas outlet connects purified gas and goes out pipe, and unloading valve is arranged on down the round platform bottom.It is characterized in that below the purified gas outlet, a funnel type baffle plate being installed.When raw gas is gone into pipe when entering housing by raw gas, both begun gravitational dust collection, under the effect of funnel type baffle plate, coal gas improves at the intravital swirl strength of shell, produce collision in the coal gas between grit and the funnel type baffle plate and continue dedusting, purified gas exports and goes out pipe through purified gas and flows out then, and dust is discharged through unloading valve.The raw gas of fly-ash separator described in the utility model is gone into pipe and is gone out pipe and can exchange use with purified gas outlet, purified gas, by advancing to become, and advances by going out to become.
The utility model and existing gravitational precipitator are relatively, by improve coal gas in fly-ash separator swirl strength and increase collision between grit and the baffle plate, significantly improved dust removal efficiency, save postorder wet dust removal water consumption, alleviate the harm of dirt mud and sewage, reduce the maintenance and the working cost of bag dust collector.This fly-ash separator is simple in structure, manufacturing is installed easily, can be used for the coal gas dust removal device transformation of coal gas dust removal He the old blast furnace of newly-built blast furnace.
Description of drawings Fig. 1 is a blast furnace gas gravitational precipitator structural representation.
Embodiment as shown in Figure 1, fly-ash separator comprises: housing (5), raw gas are gone into pipe (2), funnel type baffle plate (4), purified gas outlet (3), purified gas goes out pipe (1), unloading valve (6).Housing upper and lower ends symmetry is circular platform type, and raw gas is gone into the side-walls that pipe (2) is positioned at round platform, and purified gas goes out pipe (1) and is positioned at the round platform top, and purified gas goes out pipe and is connected with purified gas outlet (3), and unloading valve (6) is arranged on down the round platform bottom.Funnel type baffle plate (4) is installed in the below of purified gas outlet (3).When raw gas is gone into pipe when entering fly-ash separator by raw gas, both begun gravitational dust collection, under the effect of funnel type baffle plate, coal gas improves at the intravital swirl strength of shell, produce collision in the coal gas between grit and the funnel type baffle plate and continue dedusting, purified gas exports and goes out pipe through purified gas and flows out then, and dust is discharged through unloading valve.
