Description

A sinter draft type vertical cooling furnace

technical field

The utility model relates to a sintered ore cooling machine, in particular to a sintered ore draft type vertical cooling furnace, which belongs to the fields of ironmaking and environmental protection.

Background technique

In recent years, with the increasingly tense relationship between energy consumption and environmental protection in my country, energy conservation and environmental protection have been valued by the whole society, making it a key measure to establish a resource-saving and environment-friendly society. Energy conservation and environmental protection work involves all aspects. Energy conservation and environmental protection in the industrial field is the focus and difficulty of energy conservation and environmental protection work, especially for the steel industry with high energy consumption and heavy environmental pollution. The energy consumption of the sintering process accounts for about 15% of the total energy consumption of iron and steel enterprises, ranking second only to the iron-making process. At present, the total amount of waste heat resources produced by 1 ton of sinter produced by large and medium-sized iron and steel enterprises in my country is about 1.44GJ, and the recycling rate is only 35% to 45%. In 2014 (891 million tons of sinter output), about 800 million GJ of sinter waste heat resources have not been recycled, resulting in waste of resources and serious environmental pollution. Therefore, the efficient recovery and utilization of waste heat resources in the sintering process has become an important direction and approach for energy saving and environmental protection in the sintering process.

The waste heat resources in the sintering process are mainly composed of two parts: one is the sensible heat of sintering ore, accounting for about 70% of the total waste heat resources; the other is the sensible heat of sintering flue gas, accounting for about 30% of the total waste heat resources. Comparatively speaking, the sensible heat quantity of sintering ore is large and the quality is high; while the sensible heat quantity of sintering flue gas is small and the quality is low. Based on this, the efficient recovery and utilization of sinter sensible heat is the core and focus of the entire sinter waste heat recovery and utilization.

At present, the sinter cooling mainly adopts the traditional belt cooler or ring cooler based on the principle of high wind quick cooling and one-time loading and unloading cooling. No matter which cooling method is used, the cooling machine has problems such as large air leakage rate, high power consumption of the fan, low recovery rate of sensible heat, and low thermal efficiency of the boiler. In other words, in the current environment where the market has increasingly stringent requirements for energy saving and green manufacturing in sintering production, it is difficult for the original equipment structure to realize efficient recovery and utilization of sensible heat of sintering ore. Therefore, it is the only way for the sinter industry to save energy and protect the environment by breaking through the limitations of traditional ring cooling or belt cooling and developing a process and technical equipment for efficient recovery of sinter sensible heat.

In the utility model, the vertical cooling furnace adopts the suction type, and the negative pressure is always maintained in the vertical cooling furnace, and the circulating fan generates negative pressure in the hot air enrichment area to draw away the hot air in it.

In the utility model, generally speaking, the vertical cooling furnace is mainly composed of a silo, a material sealing material distribution pipe, a tower body, an air inlet and discharge device, a material discharge device and an exhaust type hot air outlet. The silo and material seal distribution pipe form a uniform feeding system. After the hot sintered ore enters the silo, it enters the material seal distribution pipe under the action of gravity, and then flows out from the material seal distribution pipe, and enters the tower top, tower wall and tower bottom. The tower body is naturally accumulated in the tower body; the cooling air enters the sinter accumulated in the tower body through the louvers on the side wall of the air inlet and discharge device, and cools the sinter; the cooled sinter flows into the air inlet under the action of gravity. In the discharge device, several air inlet and discharge devices are evenly arranged along the circumferential direction of the tower bottom to ensure that the sinter passing through the air inlet and discharge device can flow down evenly; the lower end of each air inlet and discharge device is connected to a Discharging equipment, through which the discharging speed of each air inlet and discharging device can be controlled. After the cooling air entering the tower body undergoes heat exchange with the hot sinter, it cools the hot sinter to below 150°C, and itself is heated to a higher temperature to become hot air. The hot air passes through the material layer and then passes through the material layer at the top It enters the material-free area at the upper end of the tower body, and then is discharged from the suction-type hot air outlet through the exhaust fan, and then enters the subsequent waste heat power generation system.

The tower body is located below the silo, and the inside of the tower body is divided into a hot air enrichment area and a cooling area from top to bottom, which is where the hot air is enriched and the hot sinter is cooled. The hot air enrichment area in the upper part is mainly the hot air enrichment place generated after heat exchange with the hot sintered ore, and the lower cooling area is the place where the hot sintered ore and the cooling air conduct countercurrent heat exchange. Since the vertical cooling furnace is of the suction type, the suction fan generates negative pressure in the hot air enrichment area above the material surface in the tower body, and draws away the hot air in the tower body. Due to the negative pressure in the hot air enrichment area, in order to prevent the cooling air from entering the tower body from the silo and the material seal distribution pipe, it is necessary to increase the height of the material seal distribution pipe. The height (or length) of the material seal distribution pipe is the tower body 30-70% of the height, preferably 40-65%, more preferably 50-60%, that is, the height of the material seal distribution pipe is higher than the height of the cooling zone in the tower. Generally, the height of the sealing and distributing pipe is 1m-10m, and more preferably, the height is 4-8m.

The air inlet and discharge device is located at the lower part of the tower body, and its main function is to provide a discharge channel for the sintered ore, and at the same time provide a channel for the cooling air to enter the tower body.

A cold air inlet is provided on the side wall of the chute, and the circulating cooling air enters the discharge chute from the cold air inlet, and then enters the inside of the tower through the air inlet and discharge device to cool the sinter.

After adding the logistics airflow control device, the central material can be diverted to the outside, which can make the air and material flow more uniform and reduce the cooling dead zone. The setting of the air outlet ring of the louvers on the side of the top plate can reduce the resistance of the inner ring air inlet and discharge device into the cooling air in the tower, which is more conducive to the uniformity of air distribution in the tower.

In the utility model, in order to make the air flow more uniform, the vertical cooling furnace also includes an edge air flow adjustment device arranged on the tower wall and a central air flow adjustment device arranged on the outer side wall of the support structure of the logistics air flow control device. The tops and bottoms of the side airflow adjustment device and the central airflow adjustment device are independently provided with multiple circles of air holes from outside to inside in the circumferential direction. After the side airflow adjustment device and the center airflow adjustment device are added, the side cooling air and the center cooling air can flow to the middle, which can make the airflow more uniform and prevent the cooling airflow caused by the short path of the airflow through the material or the edge effect. Many places flow out from the side or the center, resulting in less cooling air for the intermediate material and poor cooling effect.

Preferably, the vertical cooling furnace also includes a plurality of temperature measuring elements, which are located on the side wall of the air inlet and discharge device and protrude into the inside of the air inlet and discharge device. Preferably, the temperature measuring element may be a thermocouple temperature sensor.
