Abstract
The utility model provides monomer and double blocks for a flue wall of a carbon roasting oven, wherein, the monomer block comprises a brick body, brick surfaces and end parts. The utility model is characterized in that (1) one side of the upper side and one side of the lower side of the brick body are provided with a large oval shaped boss or a large oval shaped groove each; (2) the other side of the upper side and the other side of the lower side of the brick body are provided with a small oval shaped groove each, the center of the groove is provided with a circular orifice pipe which is perforated from bottom to top; (3) the length between two ends of the brick body of the side with the large oval shaped groove is larger than the length between two ends of the brick of the side with the small oval shaped groove, thereby forming a small platform with parallel end parts. The double block is the symmetric unfolding of the monomer block. When the blocks are used to lay the flue wall, the blocks can form a horizontal flue and a vertical flue against the side of a hopper, so that asphalt flue gas is introduced into a combustion area to combust, thereby achieving the aim of purifying the flue gas.
Description
Technical field:
The utility model belongs to the technical field for the roaster of aluminum electrolyzing cell used carbon product sintering typing, is specifically related to a kind of profiled concrete-block of carbon roasting furnace quirk wall.
Background technology:
The carbon roasting furnace of using for matched with aluminium electrolyser of prior art has the multiple type of furnace of formula roaster at the bottom of ring-form calcining furnace, tunnel cave, down-draft kiln, the car, and ring-form calcining furnace is divided into two kinds of formula with cover and open types.Ring-form calcining furnace is made up of firing chamber, quirk wall, coal gas (or other fuel) pipeline, waste gas flue and bell (for formula with cover) etc.A roaster has many furnace chambers of 20-90 usually, each furnace chamber is formed (being generally 7 casees 8 quirks or 8 casees 9 quirks) by the charging box of many quirks and a plurality of dress anode carbon blocks, and its quirk wall is normally built by laying bricks or stones with the refractory material building block (high-alumina refractory special form brick) that is shaped as special-shaped cuboid and formed.
Chinese patent ZL200520200435.7G discloses a kind of " quirk of open type ring-form calcining furnace draws brick ", in order to reduce resistance to the flue gas circulation, on the brick body, be provided with two upper and lower relative arcwall faces, during installation the arcwall face of brick body placed in face of airflow direction.Chinese patent ZL200520200436.1 then discloses a kind of " the hopper checker brick of ring-type baking furnace with cover ", on two end faces of brick body, be provided with tongue-and-groove, and on other two end faces of brick body, be provided with joint tongue, build the bulk strength that hopper both can increase brick wall greatly by laying bricks or stones with this checker brick, also can improve the seal of charging box.Each all has certain advantage technique scheme, yet they are still for the integrated artistic condition of roaster and do not have great influence.
The utility model content:
The scientific and technical personnel that are engaged in carbon industry know that the main body of carbon roasting furnace is that its heater is the quirk wall, have only the structure of reforming the quirk wall just most possibly to improve the integrated artistic condition of roaster.The utility model proposes a kind of building block (brick) of novel carbon roasting furnace quirk wall, build the structure that the quirk wall can be reformed the quirk wall by laying bricks or stones with it, thereby can improve the integrated artistic condition of roaster greatly.
The building block of carbon roasting furnace quirk wall of the present utility model comprises brick body, brick face and end, it is characterized in that:
(1) side at brick body upper and lower faces is respectively arranged with a large semi-circular boss or a large semi-circular groove;
(2) opposite side at brick body upper and lower faces then is respectively arranged with a smaller part circular groove, and the middle part of groove has the circular hole pipe of a up/down perforation;
(3) length between the brick body two ends of a side of band large semi-circular groove promptly forms parallel chain-wales at its two ends greater than with the length between the side brick body two ends of little semi-circular grooves.
Carbon roasting furnace quirk wall of the present utility model building block, the large semi-circular groove of one side and large semi-circular boss play the effect of tongue-and-groove and joint tongue when building the quirk wall by laying bricks or stones.And the smaller part circular groove of its opposite side is synthesized a pipe when building the quirk wall by laying bricks or stones, has just formed the interconnection of bitumen flue gas, and the circular hole pipe of groove middle part up/down perforation has then formed the vertical passage of bitumen flue gas accordingly.When building the quirk wall by laying bricks or stones, a side side of band large semi-circular groove (or band large semi-circular boss) is placed on quirk one side, and a side of band small circular groove is placed on charging box (charcoal piece case) side.Perps between two building blocks blocks with refractory wass at end parts parallel small boss place.Like this, only do not have a side of parallel small boss to form perps in the end, the bitumen flue gas that evaporates from charging box can only enter interconnection the building block from this perps.Bitumen flue gas transversely passage and vertical passage is guided combustion system into, has avoided bitumen flue gas to discharge without abundant burning.
Carbon roasting furnace quirk wall of the present utility model building block, its specification can be determined according to the size of roaster charging box and quirk wall.But in principle, the width with a side of big groove approximately is twice than the width of band minor groove one side; And, make the building block two ends form two parallel small boss with the two ends distance 1-2 millimeter of big groove one side two ends distance than band minor groove one side.Like this, when with concrete block masonry quirk wall of the present utility model, smear full refractory wass, and do not smear refractory wass, therefore form the perps of 2-4 millimeter by charging box one side by the perps of charging box one side by the perps of the 1-2 millimeter between the small boss of quirk one side.Bitumen flue gas just can be by this side perps, guided to the combustion zone by the interconnection in the building block of quirk wall and vertical passage and burn, reach the purpose that purifies flue gas.
The utility model also provides the binary building block identical with above-mentioned monomer structure, is about to above-mentioned building block symmetry and launches.It comprises brick body, brick face and end, it is characterized in that:
(1) is respectively arranged with a large semi-circular boss or a large semi-circular groove in the both sides of brick body upper and lower faces center line;
(2) then be respectively arranged with a smaller part circular groove on the both sides, the outside of brick body upper and lower faces, the middle part of groove has the circular hole pipe of a up/down perforation;
Between (3) two band large semi-circular grooves brick body two ends between length greater than the length between the band smaller part circular groove brick body two ends, the outside, promptly its two ends form end parts parallel chain-wales.
Other parameter and the monomer building block of binary building block are roughly the same, repeat no more herein.The quirk that this binary building block is particularly suitable for doing roaster draws brick to use.
