Description

Vertical sinter cooler with material level adjustment device and sinter cooling method

technical field

The invention relates to a vertical sinter cooler with a material level regulating device and a sinter cooling method, belonging to the fields of ironmaking and environmental protection.

Background technique

In the modern sintering process, "cooling" is one of the most critical processes. After the sintered ore has been roasted by the sintering machine, it has formed a high-temperature finished ore. How can it be protectively cooled without affecting its quality and yield, so that it can be sent to the finished product ore bin through a belt conveyor, and at the same time The perfect recovery and utilization of the sensible heat energy it carries has always been a problem that technicians in the industry have been constantly studying. Since the 1960s, the cooling process of sinter has been developed rapidly, which is mainly divided into three categories: belt cooling, ring cooling and disk cooling. In the late market competition, the strip cooling technology was eliminated, and the remaining ring cooling and disk cooling technologies each have their own advantages and disadvantages. However, comprehensive comparison shows that the waste heat utilization rate of disk cooling is better than that of ring cooling (all sensible heat of sinter can be recycled), so disk coolers are widely used in foreign markets, and this patent also elaborates on the technology of disk coolers.

The technology of disk coolers has been developed since the 1970s. At the beginning, it was horizontal disk cooling, that is, the cooling air flows from the inner ring to the outer ring of the disk cooler, and passes through the material layer to be cooled to exchange heat with it. The cooling air is directly discharged to the atmosphere. This is neither economical nor environmentally friendly. After years of continuous research and optimization, the latest disk cooler technology is the "ventilated longitudinal disk cooling technology" proposed by Japan's Mitsubishi Hitachi and Zhongsheng Iron and Steel. This technology adopts air extraction, which draws the cooling air from the atmosphere into the bottom of the material to be cooled, then passes through the material layer vertically upwards, and finally blows out from the upper part of the material layer to enter the subsequent process. Compared with the original scheme, this scheme has been greatly optimized and improved. The following will introduce this scheme in detail.

JP2008232519A (Mitsubishi Hitachi and Zhongsheng Iron and Steel, hereinafter referred to as D1) discloses the ventilation type longitudinal plate cooling technology, see Figure 1 in it: hot sintered ore falls from the tail of the sintering machine into the feed chute, and accumulates in the chute to form a certain height of material Column, on the one hand, it can play the role of uniform feeding, on the other hand, it can play the role of material sealing to prevent the air from passing through the feeding port. The mineral material continues to pass through the hood and then enters the cooler box, pushing it into a material column of a certain height. At the same time, affected by the negative pressure of the exhaust fan, the air near the plate cooler will be sucked into the material column through the louver air intake device, and pass through the material column from bottom to top to exchange heat with it. The top surface of the material column passes through the air outlet, is sent to the gravity dust collector and waste heat boiler, and finally is discharged outside after passing through the exhaust fan. After being cooled by air, the sintered material forms an annular accumulation area with a cross-section of a 37-degree accumulation angle triangle at the lower tray of the plate cooler. When it is rotated to the unloading area, the sintered material is scraped off by the scraper device to complete the cooling process. Enter the next process link.

Although Mitsubishi Hitachi and Zhongsheng Steel's "ventilated longitudinal plate cooling technology" has made significant progress compared with conventional technologies, it still has the following five defects:

1) The overall height requirement of the device is too high: since the "ventilated longitudinal plate cooling technology" adopts the draft method, it is necessary to install a material seal at the position of the feed inlet, that is, the material column accumulated in the feed chute in Figure 1 of D1, The height of the material seal is 1.2 to 1.5 times the height of the material column in the cooler box as the standard. In this way, the height of the entire set of plate coolers is virtually increased. During construction and installation, either the elevation of the entire sintering machine needs to be raised, or the civil engineering plane of the plate cooler needs to be dug down. No matter which way you choose, it will cause a high investment cost, which is not cost-effective in terms of economic indicators;

2) The open circulation of the air flow leads to low utilization rate of waste heat and pollutes the environment: Since the air flow of the "extraction type longitudinal plate cooling technology" is an open circuit circulation, the air from the waste heat boiler is directly exhausted and not recycled, resulting in more than 100 Sensible heat of the air at a high temperature is wasted, and the discharged air contains a large amount of small particles of dust, causing a certain degree of particle pollution to the atmosphere;

3) The material at the feed inlet is severely worn: due to the "ventilated longitudinal plate cooling technology" that sets the material seal at the feed chute, there will be a friction distance between the lower part of the material seal and the upper layer of the material surface in the plate cooler box. At this time, the sintered material is easily pulverized and broken when it is rubbed under the double-layer harsh working conditions of high temperature and upper material column extrusion, thereby reducing the yield of the sintering machine;

4) The environmental pollution is serious: due to the negative pressure ventilation technology adopted in the "ventilation type longitudinal plate cooling technology", it does not set a sealing cover device at the lower tray of the box body. In this way, when the sintered ore is scraped off by the scraper device, it is easy to cause a large number of fine particles and dust to splash. And once the exhaust fan breaks down, all the material dust pushed around the plate cooler will enter the atmosphere, causing extremely bad influence on the operating environment next to the machine.

5) The thermal efficiency of the waste heat boiler has not reached the highest level: because the "draft-type longitudinal plate cooling technology" does not accurately classify the air passing through the material layer according to the air temperature, but mixes it all into the waste heat boiler, so when the outlet air temperature of the low-temperature section is too low , it will inevitably lower the temperature of the air entering the waste heat boiler, thereby reducing the thermal efficiency value of the waste heat boiler.

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.
