Because the smoke dust has cohesiveness, and the integral temperature of the flue is lower than the temperature in the metallurgical furnace, the smoke gas is easy to adhere to the inner wall surface of the flue and form a clinker when meeting cold in the flue, the flow area of the smoke gas in the flue is reduced along with the thickness increase of the clinker bonding layer, the flow resistance of the smoke gas in the flue is increased, the smoke gas can not flow smoothly in the flue, if the smoke gas can not be timely discharged from the material entering the furnace, the pressure in the furnace is increased, the reaction condition in the furnace is changed, the air inflow of the subsequent boiler section is changed, and the production and maintenance are stopped if necessary.

The prior art generally only considers the anti-stick treatment for a certain period of time in the formation of the bond, and cannot do the whole process of anti-stick before, during and after bonding. For example, the paint on the inner wall surface of the flue can reduce the adsorption effect only in the contact process of the flue gas and the inner wall of the flue, but the paint cannot actively inhibit the approach of the flue gas to the wall surface of the flue (before bonding) and cannot be actively broken after bonding (after bonding), once the first layer of slag blocks are formed in the flue, the protection effect can be obviously disabled, the subsequent flue gas has strong adsorption force on the first layer of slag blocks, and then the smoke can be quickly gathered in a short time to form large-area bonding.

Further, the upper end of the first channel 23 is communicated with the gas inlet 21, the external shielding gas is introduced into the first channel 23 through the gas inlet 21, the upper end of the second channel 24 is closed, so that the external shielding gas in the first channel 23 and the external shielding gas in the second channel 24 are discharged through the gas outlet 22, and the external shielding gas discharged from the gas outlet 22 on the adjacent shielding gas distributor 2 can form a gas circulation between the adjacent shielding gas distributors 2, so that the contact between the flue gas in the chamber 111 and the inner wall surface of the vertical part 11 and the wall surface of the horizontal part 12 is restrained, the contact between the flue gas and the inner wall surface of the vertical part 11 and the wall surface of the horizontal part 12 is reduced, and the discharge of the flue gas is facilitated.

The gas circulation makes the dwell time of external shielding gas in accommodation space 3 longer, flow more stable, makes in accommodation space 3 can keep higher gas pressure, and prevents that external shielding gas from directly all dispersing in the flue gas after flowing out accommodation space 3 to reduce external shielding gas's unit flow, and then reduced external shielding gas's influence to flue gas flow, still reducible circulation gas's outflow, avoid the flue gas to flow into accommodation space 3.

In addition, if the wall surface of the horizontal part 12 facing the center of the flue is integrally bonded, the flow of the external shielding gas into the chamber 111 is blocked, and the gas circulation is disturbed in one direction relative to the flue gas flowing in one direction, so that the better breaking effect is achieved.

In addition, the direction of the circulating surface of the circulating gas is perpendicular to the flow direction of the flue gas, so that the circulating gas in the accommodating space 3 and the circulating gas overflowed out of the accommodating space 3 can not influence the flow velocity of the flue gas in the vertical direction.
