Description

Technical Field

[0001] This utility model relates to the field of lime production technology, and in particular to a dust removal system for the discharge of a double-chamber lime kiln. Background Technology

[0002] A double-chamber lime kiln is a device used for producing lime. It typically consists of two adjacent cylindrical chambers: a preheating chamber and a combustion chamber. Limestone and fuel are fed into the preheating chamber through the feed inlet. After preheating, the limestone enters the combustion chamber for calcination. During combustion, the high-temperature flue gas generated by fuel combustion passes through the preheating chamber to preheat the limestone, thus accelerating the decomposition and calcination reaction. Double-chamber lime kilns offer several advantages, including flexibility, high efficiency, and sustainability. They can adapt to different types of limestone and fuel and can be adjusted and controlled as needed. Furthermore, the presence of the preheating chamber shortens the calcination time of the limestone, thereby improving production efficiency. Double-chamber lime kilns can also reduce energy consumption and environmental impact by recovering and reusing the heat energy in the flue gas. Dust removal treatment is usually required for the discharge from double-chamber lime kilns to reduce the environmental and health impacts of emitted particulate matter. Generally, the dust is collected first and then treated with dust removal technology.

[0003] Existing dust removal methods for double-chamber lime kilns generally rely solely on air filters or dust collection bags for dust filtration. However, these methods are ineffective, the dust collection bags are prone to damage, and the filters are easily clogged, requiring frequent replacement or cleaning, which increases maintenance costs.

[0004] Therefore, we propose a dust removal system for the discharge of a double-chamber lime kiln. Utility Model Content

[0026] Example 1: A dust removal system for the discharge of a double-chamber lime kiln, such as... Figures 1-2 As shown, the system includes a preliminary dust removal mechanism 10, and a circulating dust removal mechanism 11 is provided on the right wall of the preliminary dust removal mechanism 10. The preliminary dust removal mechanism 10 includes a first fan 12, one end of which is fixedly connected to the discharge port of the double-chamber lime kiln through a connecting pipe, and the other end of which is fixedly installed with a cylinder 13 through a connecting pipe. By setting up the preliminary dust removal mechanism 10 and the circulating dust removal mechanism 11, the dust generated when the lime kiln discharges can be treated twice, resulting in better dust removal effect. At the same time, the setting of the circulating dust removal mechanism 11 can recycle the water after dust removal, reducing the waste of water resources. Furthermore, the liquid filter screen 23 can filter impurities in the circulating water, preventing impurities from clogging the pipes and improving the practicality of the dust removal system.

[0027] Example 2: Based on Example 1, as follows Figure 2 As shown, a bracket 14 is fixedly installed on the outer wall of the cylinder 13, a discharge valve 15 is provided at the bottom of the cylinder 13, a ventilation pipe 16 is fixedly installed on the upper end of the inner wall of the cylinder 13, a second fan 17 is provided at the top of the ventilation pipe 16 through a connecting pipe, and the other end of the second fan 17 is fixedly connected to the left side wall of the circulating dust removal mechanism 11 through a connecting pipe. By setting an air filter 19, the air after dust removal can be filtered again, which further improves the dust removal effect. At the same time, the setting of the air filter 19 can also prevent impurities from entering the dust removal water tank 18, thus protecting the normal operation of the dust removal system.

[0028] Example 3: Based on Examples 1 and 2, as follows... Figure 3As shown, the circulating dust removal mechanism 11 includes a dust removal water tank 18, and the left side wall of the dust removal water tank 18 is fixedly connected to one end of the second fan 17 through a connecting pipe. An air filter 19 is fixedly installed on the top of the dust removal water tank 18, and an exhaust pipe 20 is fixedly installed on the top of the air filter 19. A circulating water pump 21 is installed at the lower end of the right side wall of the dust removal water tank 18 through a connecting pipe. A circulating water tank 22 is fixedly installed on the top of the circulating water pump 21 through a connecting pipe, and the lower end of the right side wall of the circulating water tank 22 is fixedly connected to the upper end of the right side wall of the dust removal water tank 18 through a connecting pipe. A liquid filter 23 is fixedly installed in the middle of the inner wall of the circulating water tank 22.

[0029] The working principle of this utility model:

[0030] In operation, the dust-laden gas from the discharge port of the double-chamber lime kiln is first drawn into the cylinder 13 by the first blower 12. Inside the cylinder 13, the gas's velocity decreases and its flow direction changes, causing larger particles to settle to the bottom of the cylinder 13 under the influence of gravity and inertia, and then discharge through the discharge valve 15. The gas, after preliminary dust removal, enters the second blower 17 through the ventilation pipe 16. The second blower 17 then sends the gas into the dust removal water tank 18, where the dust particles are absorbed by the water. The purified gas is further filtered through the air filter 19 and finally discharged through the exhaust pipe 20. Simultaneously, the circulating water pump 21 pumps the water from the dust removal water tank 18 to the circulating water tank 22, where impurities are filtered through the liquid filter 23. The water is then returned to the dust removal water tank 18, forming a cycle. This not only improves dust removal efficiency but also saves water resources.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
