Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical sintering fume treatment, in particular to a device for controlling uniform feeding of activated carbon in an activated coke system. Background Art

[0002] Activated coke desulfurization and denitrification technology can simultaneously treat multiple pollutants, that is, remove SO2, NOx, dioxins and other pollutants at the same time. This technology is widely used in the steel industry, especially in sintering flue gas desulfurization and denitrification. This technology uses the non-selective adsorption and catalytic effects of activated coke to absorb and remove multiple pollutants, thereby achieving the purpose of purifying flue gas. Activated carbon for desulfurization and denitrification for sintering is a cylindrical activated carbon made of coal. It uses high-quality anthracite as raw material, adds a binder to extrude and then undergoes carbonization, cooling, activation, washing and other processes. It has a developed void structure, good adsorption performance, high mechanical strength, fast absorption speed, high capacity, large specific surface area, strong regeneration and other characteristics. Activated carbon is the main adsorption catalyst. Before the activated coke desulfurization and denitrification system works normally, a large amount of activated carbon needs to be added to the adsorption tower. The adsorption tower is filled with activated carbon to start normally according to the program. After filling with activated carbon, the temperature in the adsorption tower is controlled not to exceed 130°C, and the activated carbon adsorption catalysis works normally. Activated carbon moves from the top to the bottom of the tower with gravity. Ideally, activated carbon at different positions falls evenly until it is removed from the adsorption tower. However, in actual operation, the activated carbon in the middle falls quickly, while the activated carbon in contact with the side wall of the adsorption tower falls slowly, which results in a high heat storage temperature of the activated carbon on the side wall, which may cause fire in serious cases. In addition, the activated carbon in the middle area falls quickly, while the activated carbon on the side wall falls slowly or does not move, which reduces the processing capacity of the activated coke system to remove multiple pollutants, and there is a risk of excessive pollutants in the sintering flue gas after treatment.

[0003] Patent No. CN201721325423.6 discloses a uniform activated carbon feeding device. This utility model mainly aims at the problem of uneven activated carbon feeding after the activated carbon discharged from the adsorption tower enters the vibrating screen to screen out the powder, and a round roller feeder is added to make the activated carbon feeding uniform. This method is suitable for controlling the uniform feeding of activated carbon in an open space, while the activated coke system adsorption tower is filled with activated carbon, which is a confined space, so this method is not suitable for controlling the feeding speed of activated carbon in the adsorption tower.

[0024] Specifically, the device also includes an external control device, and the control device is used to receive the monitoring data of the ultrasonic velocimeter 10 in real time, and prompt the driving machine 11 to drive the left rotating shaft 3 or the right rotating shaft 7 to rotate according to the monitoring data, which is conducive to the unification of the activated carbon discharge speeds of the four discharge ports, reducing the risks of activated carbon ignition and excessive discharge of sintering flue gas, and the ultrasonic velocimeter 10 is a conventional device currently on the market, and has not been improved. Its principle is mainly based on the propagation speed of ultrasonic waves and the reception time difference, and the device is already well known to technical personnel in various industries, and is installed and applied according to the actual installation environment during installation and use.

For the existing control devices in the outside world, their receiving and sending operations are well known to technical personnel in this field, and can be independently completed according to computer program programming. Therefore, this article does not elaborate on this.

[0025] The sizes of the left small triangular prismatic divider 2 and the right small triangular prismatic divider 6 are respectively proportionally reduced sizes of the large triangular prismatic divider 9, the cross-sections of the left small triangular prismatic divider 2, the right small triangular prismatic divider 6 and the large triangular prismatic divider 9 are all equilateral triangles, the cross-sectional side lengths of the left small triangular prismatic divider 2 and the right small triangular prismatic divider 6 are equal, and the sizes of the left small triangular prismatic divider 2 and the right small triangular prismatic divider 6 are respectively 1 / 4 of the size of the large triangular prismatic divider 9.

[0026] The opening and closing angle value of the bottom edge of the left small triangular prism divider 2 and the left baffle 4 is 30°~150°, and the opening and closing angle value of the bottom edge of the right small triangular prism divider 6 and the right baffle 8 is 30°~150°.

[0027] According to the above example: when the opening and closing angle value of the bottom edge of the left baffle plate 4 and the left small triangular prism-shaped divider 2 is 120°, the opening and closing angle of the bottom edge of the right baffle plate 8 and the right small triangular prism-shaped divider 6 is 60°, and at this time, the left baffle plate 4 and the right baffle plate 8 are symmetrically arranged with the large triangular prism-shaped divider 9 as the central axis, and when the opening and closing angle values ​​of the left baffle plate 4 and the right baffle plate 8 are adjusted, the total opening and closing angle of the two is 180°.

It is then known through actual use that at this time, the activated carbon at the four discharge ports all descends evenly at a speed of 1m / min, which effectively solves the problem of uneven discharge of activated carbon and reduces the risk of activated carbon ignition and excessive discharge of sintering flue gas.
