Description

Technical Field

[0001] This utility model relates to the field of metallurgical flue gas treatment technology, specifically to a metallurgical high-temperature flue gas dust collection and conveying device that is easy to maintain. Background Technology

[0002] In the metallurgical industry, the collection and transportation of high-temperature flue gas is a crucial step in ensuring the normal operation of the production environment and equipment. Traditional high-temperature flue gas collection and transportation devices are widely used in various metallurgical production scenarios. Their main purpose is to collect dust from high-temperature flue gas and then rationally discharge or reuse the purified gas, attempting to meet the basic requirements of metallurgical production for flue gas treatment, thereby reducing environmental pollution and ensuring smooth production.

[0003] In traditional dust collection and conveying devices, the filter plates are usually fixed inside the equipment. When the filter plates need to be cleaned or replaced, a large number of surrounding parts often need to be removed, which is cumbersome, time-consuming, and labor-intensive. This not only increases maintenance costs but also affects production efficiency due to prolonged downtime. For example, the filter plates of some devices are sealed in complex structures, and maintenance personnel need to use a variety of tools and spend a lot of time to remove them, which seriously affects the normal operation and maintenance efficiency of the equipment. The ash discharge system of traditional devices is relatively simple in design, and dust is prone to blockage during the discharge process. Due to the complex characteristics of dust in metallurgical high-temperature flue gas, which may contain sticky substances or large particulate impurities, simple ash discharge channels cannot effectively handle these situations, leading to dust accumulation, affecting the dust collection effect, and even causing equipment failure.

The filter box 3 is provided with a mounting groove 18 opposite to the slot 15. The filter plate 401 passes through the mounting groove 18 and is located in the slot 15. The sealing plate 402 is detachably connected to the filter box 3.

[0027] Preferably, the filter box 3 is a hollow rectangular body, the slot 15 is a "U" shaped structure, and the two ends of the spring 17 are fixedly connected to the bottom end of the slot 15 and the ejector plate 16, respectively.

[0028] Preferably, the filter box 3 is provided with screw holes 19 around the mounting groove 18, and the sealing plate 402 is provided with through holes 20.

[0042] Preferably, the outer wall of the flue gas treatment box 11 is provided with a rotating hole, and bearings are provided in the rotating hole and on the inner wall of the flue gas treatment box 11.

The controller is connected to an external power supply through wires, thereby controlling the first motor 902, the second motor 25 and the ultrasonic generator 23 to be powered on and operated.

[0044] The working principle of this utility model is as follows: High-temperature flue gas enters the filtration zone 7 from the inlet pipe on one side of the filter box 3. The filter box 3 is equipped with a filter plate 401, and the top of the filter plate 401 is connected to a sealing plate 402 and fixed to the filter box 3 by bolts. When the flue gas passes through the filter plate 401, dust is intercepted on the filter plate 401, and the purified gas continues to flow upward. When it is necessary to replace or clean the filter plate 401, the bolts are unscrewed, and under the action of the spring 17 at the bottom of the slot 15, the pop-out plate 16 pops the filter plate 401 upward, making it easy to remove the filter plate 401 for maintenance. The operation is convenient and quick. The filtered dust falls into the ash hopper 501, which is connected to the vertical pipe 502. The first motor 902 at the bottom of the vertical pipe 502 is started, and the output end of the first motor 902 drives the spiral conveyor roller. As the screw conveyor roller 901 rotates, the dust moves downward along the vertical pipe 502 under the action of the screw conveyor roller 901 and is discharged through the ash discharge pipe 10, effectively preventing dust blockage and ensuring the continuity of the dust collection process. The filtered high-temperature gas enters the flue gas treatment box 11 through the exhaust pipe 13. The flue gas is dispersed into the water in the flue gas treatment box 11 through the smoke dispersing holes 1402 on the smoke dispersing plate 1401. The second motor 25 on one side of the flue gas treatment box 11 drives the rotating rod 1201 and the fine mesh plate 1202 on the surface to rotate, which refines the bubbles, increases the contact area between the gas and water, improves the heat exchange efficiency, and realizes waste heat recovery. The water inlet pipe 26 at the top of the flue gas treatment box 11 can replenish cold water, the drain pipe 28 at the bottom discharges hot water for other purposes, and the exhaust pipe 27 on the top side discharges the cooled gas.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
