Description
Technical Field
The invention belongs to the field of coke production, and particularly relates to a vertical heat recovery coke oven.
Background
Coke is one of basic raw materials in the steel industry, a traditional coke oven is a chamber type coke oven, and the biggest disadvantage of the coke oven is serious pollution, and although a plurality of pollution control measures are adopted, the pollution problem cannot be completely eliminated, so the coke oven is a pollution source for important treatment in China at present.
The pollution-free coking method is studied at the beginning of the foreign country in the eighties of the twentieth century, a novel coke oven is put into production, namely, a clean heat recovery coke oven is the biggest difference from the traditional machine coke oven in that the coke oven is operated under negative pressure, and the volatile matter is completely combusted in the oven, so that the escape of harmful gas is avoided, and the environment is protected.
At present, two clean heat recovery coke ovens, namely a horizontal heat recovery coke oven and a vertical heat recovery coke oven, are long in horizontal development history and mature in technology, but compared with a vertical heat recovery coke oven, the two clean heat recovery coke ovens occupy large space, have large investment and high energy consumption. The vertical heat recovery coke oven has few oven types at present, and has the following defects: the furnace body has the defects of poor structural strength, difficult coke pushing, few control means, uneven heating, low waste heat utilization efficiency and the like.
Because the existing vertical heat recovery coke oven flue is arranged at the bottom of the oven body, a plurality of holes are formed in the wall supporting the coke oven, the strength of the wall is seriously weakened, and the protection device of the oven body cannot effectively protect the oven body due to the structure, so that the service life of the coke oven cannot meet the design requirement. The design life of the coke oven is generally not less than 25 years, and the life of the coke oven is longest and is less than 15 years. In addition, as the position of the vertical heat recovery coke oven flue is designed at the bottom of the coke oven, the base temperature of the coke oven is too high, the heat loss is larger, and compared with the existing horizontal heat recovery coke oven, the energy of the heat recovery coke oven is lower.
The coal charged into the heat recovery coke oven has lower volatile matters than the traditional coke oven, the volatile matters of the coal are combustible matters, and the heat recovery coke oven is required to completely burn the combustible matters in the oven, so that the fact that the temperature in the oven exceeds the load softening point of refractory materials used for building the coke oven is likely to be caused by too high volatile matters, and the oven body is deformed. However, the low volatile content causes little shrinkage of the coal after coking, and the heating mode of the heat recovery coke oven determines that the shrinkage of the same volatile content is lower than that of a traditional coke oven. The width of the carbonization chamber of the existing vertical heat recovery coke oven is designed according to the size of a traditional coke oven, the shrinkage rate is too low, the coke and the oven wall can not be completely separated, the friction between the coke and the oven wall causes difficulty in pushing the coke, and the oven wall is possibly deformed and damaged by forced pushing the coke.
Only the air entering the coke oven can be manually adjusted, the gas entering each combustion flame path can not be controlled, and the pressure of each hole can not be controlled, so that the consistency of the holes and each flame path of each hole can not be ensured, and the efficiency of the coke oven is reduced.

According to the invention, the manual regulation function of each flame path is added, so that the same transverse temperature of the coke oven is ensured. And an automatic control system for the pressure and air of each hole is additionally increased, so that the operating pressure of each hole is ensured to be consistent, and the production efficiency of the coke oven is effectively improved.
The above embodiment is not limited to the structure of the high temperature automatic control valve 18, and only needs to satisfy the corresponding adjusting function, and the present embodiment specifically describes the structure of the high temperature automatic control valve 18.
The high-temperature automatic control valve 18 comprises a valve body 181 and an actuating mechanism 182, wherein a valve plate 184 is arranged in the valve body 181, and when the valve is regulated, the actuating mechanism 182 drives the valve plate 184 to move from bottom to top through a connecting mechanism 185, so that the opening and closing degree between the valve plate 184 and the valve cavity 183 is regulated.
The connecting mechanism 185 comprises a movable frame 1851, guide wheels 1852 and a connecting rod 1853, wherein the movable frame 1851 is connected with the actuating mechanism 182 and moves upwards under the driving of the actuating mechanism 182, the guide wheels 1852 are fixedly arranged on two sides of the valve body 181 and are matched and installed in guide rails on the inner side of the movable frame 1851, and the connecting rod 1853 is positioned below the movable frame 1851 and is connected with the valve plate 184.
The high-temperature automatic control valve 18 in the embodiment changes the moving direction of the existing valve plate 184 into a downward-upward movement, so that the valve plate 184 can not receive the tensile stress caused by the dead weight of the valve plate 184 in the valve adjusting process.
