Description

Technical Field

[0001] The utility model belongs to the technical field of flue gas treatment, and in particular relates to a flue gas treatment device for a heating furnace. Background Art

[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to the rolling and forging temperature. Heating furnaces are used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals. When using a heating furnace to make steel, a large amount of flue gas will be generated, and the flue gas will contain impurities. By collecting the flue gas, the energy carried by the flue gas can be used reasonably. The used flue gas needs to be professionally treated before it can be discharged to prevent air pollution.

[0003] Traditionally, flue gas must be filtered once during the treatment process. When using clean water as a medium to filter the flue gas, when the clean water needs to be replaced after a period of use, it is usually necessary to temporarily close the flue gas discharge channel to reserve time for the replacement of clean water or adjust the pipeline valve to control the direction of the flue gas. The operation is relatively cumbersome and the flue gas treatment action cannot be continuously operated, which will delay a certain amount of time and affect the efficiency of equipment use.

[0004] Therefore, it is necessary to provide a new flue gas treatment device for a heating furnace to solve the above technical problems. Utility Model Content

The connecting pipe 3 is U-shaped, and both ends of the connecting pipe 3 are sealed. A transmission pipe 4 is fixedly installed on the top of the connecting pipe 3. The transmission pipe 4 can transmit the filtered gas in the water storage tank 1 to other equipment. A connecting box 5 is fixedly installed on the top of the water storage tank 1. A partition 6 is fixedly installed on the bottom inner wall of the water storage tank 1, and both sides of the partition 6 are fixedly connected to the inner walls of the water storage tank 1 on both sides. A baffle 7 is slidably installed on the partition 6, and electric push rods 8 are fixedly installed on both sides of the partition 6. A movable plate 9 is fixedly installed on the top of the baffle 7, and a sealing gasket is fixedly installed on the top of the movable plate 9. The sealing gasket contacts the top inner wall of the water storage tank 1. The width of the movable plate 9 is wider than the movable hole 18 mentioned below, so the movable plate 9 cooperates with the sealing gasket to ensure the sealing of the partition 6. The output rods of the two electric push rods 18 are fixedly connected to the bottom of the moving plate 9, a screw 10 is rotatably installed on the connection box 5, a motor 11 is fixedly installed on one side of the connection box 5, the output shaft of the motor 11 is fixedly connected to one end of the screw 10, a sliding block 12 is threadedly installed on the screw 10, a fixing frame 13 is fixedly installed at the bottom of the sliding block 12, two support plates 14 are fixedly installed on the top inner wall of the fixing frame 13, and electric push rods 2 15 are fixedly installed on the two support plates 14. A same pressing plate 16 is fixedly installed on the output rod of rod 2 15, the bottom of the pressing plate 16 is in contact with the top of the water tank 1, a delivery pipe 19 is fixedly installed on the pressing plate 16, the bottom end of the delivery pipe 19 extends into the water tank 1, a bellows 17 is fixedly installed on the top of the delivery pipe 19, a movable hole 18 is opened on the top of the water tank 1, the delivery pipe 19 is slidably installed in the movable hole 18, a butt joint pipe 20 is fixedly installed on one side of the connecting box 5, and one end of the butt joint pipe 20 is fixedly connected to the top of the bellows 17.

[0021] In order to ensure the stability of the positions of the two electric push rods 2 15 and the two electric push rods 1 8, two U-shaped clamps 1 are fixedly installed on one side of the two support plates 14, and the four U-shaped clamps 1 are fixedly connected to the two electric push rods 2 15 respectively. Two U-shaped clamps 2 are fixedly installed on both sides of the partition 6, and the four U-shaped clamps 2 are fixedly connected to the two electric push rods 1 8 respectively.

[0022] In order to reserve enough movable space for the movable plate 9 and the bellows 17 , a rectangular hole is opened on the top of the partition 6 , and the movable plate 9 is slidably installed in the rectangular hole. A square hole is opened on one side of the fixing frame 13 .

[0023] In order to facilitate the injection of liquid sewage into the water storage tank 1, two liquid infusion tubes are fixedly installed on both sides of the water storage tank 1, and valves are installed on the four liquid infusion tubes.

[0024] The working principle of the flue gas treatment device of the heating furnace provided by the utility model is as follows:

[0025] In the initial state, the output rods of the two electric push rods 15 are in the output state, the pressure plate 16 is in contact with the top of the water tank 1, and the movable plate 9 is also in contact with the top inner wall of the water tank 1. The delivery pipe 19 is located in the left space in the water tank 1. An appropriate amount of clean water is injected into the water tank 1 through two infusion pipes until the liquid level is higher than the bottom inner wall of the rectangular hole and lower than the movable plate 9, and then injected into the bellows 17 through the docking pipe 20, and then transmitted to the delivery pipe 19 by the bellows 17, and enters the water on the left side of the water tank 1 through the bottom end of the delivery pipe 19. The flue gas contacts the water, and the impurities in the flue gas will be mixed into the water, and the gas without impurities will float out of the water, enter the connecting pipe 3 through an installation pipe 2, and finally enter the connecting device through the delivery pipe 4.

[0026] When the clean water in the left space of the water storage tank 1 needs to be replaced after being used for a period of time, the two electric push rods 1 8 are started, and the output rods of the two electric push rods 1 8 will retract inwards at the same time, driving the movable plate 9 to gradually move downward. After the movable plate 9 moves down to a predetermined position, the movable plate 9 will be submerged in the water, and then the two electric push rods 2 15 are immediately started, and the output rods of the two electric push rods 2 15 will retract inwards at the same time, driving the conveying pipe 19 to move upward through the pressing plate 16 until the pressing plate 16 is moved to a predetermined position. The bottom end of the conveying pipe 19 is always submerged in the water during the movement, ensuring that the smoke transmitted from the conveying pipe 19 is always injected into the water. After the pressing plate 16 drives the conveying pipe 19 to reach a specific height, the motor 11 is started, and the output shaft of the motor 11 drives the conveying pipe 19 fixed thereto. The connected screw 10 and the sliding block 12 will gradually slide to the right on the screw 10. While the sliding block 12 moves, it will drive the delivery pipe 19 through the fixing frame 13 and the pressure plate 16. The delivery pipe 19 will pass through the rectangular hole into the right side space of the water tank 1. Then the motor 11 will automatically shut down, and the two electric push rods 1 8 will start again to push the moving plate 9 to gradually slide upward, blocking the rectangular hole on the partition 6. Then the two electric push rods 2 15 will also start, driving the pressure plate 16 and the delivery pipe 19 to move downward until the bottom end of the delivery pipe 19 is moved to the height in the initial state. At this time, the position of the delivery pipe 19 has been adjusted, which is convenient for cleaning the sewage on the left side of the water tank 1 and injecting clean water into the left side space of the water tank 1 again, so as to facilitate the next round of continued use.
