Abstract
Description
Technical Field
[0001] This utility model belongs to the field of submerged arc furnace technology, and in particular relates to a water-cooling device for recovering and purifying submerged arc furnace gas. Background Technology
[0002] A submerged arc furnace, also known as an electric arc furnace or resistance furnace, is mainly used for the reduction and smelting of ores, carbonaceous reducing agents, and solvents. It primarily produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and ferrosilicon-manganese alloys, serving as crucial equipment for producing industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. Therefore, when using submerged arc furnaces to recover and purify coal mines, high-temperature coal gas is generated, necessitating the use of water-cooling devices.
[0003] Existing water-cooling devices mostly use spray cooling to cool high-temperature coal gas. However, this method is wasteful of coolant, requiring filtration during coolant recovery, which increases cooling costs. Furthermore, these devices cannot operate synchronously with the coal gas flow, failing to achieve synchronized operation between the gas and coolant. Therefore, we provide a water-cooling device for recovering and purifying blast furnace coal gas to solve the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a water-cooling device for recovering and purifying blast furnace gas. By spirally winding the circulating cooling pipe around the flowing gas pipe, the gas can be rapidly cooled. At the same time, the linkage plate and the direction of gas flow ensure that the coolant can circulate according to the entry of the gas, so as to realize the synchronous alternation of gas and coolant.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a water-cooling device for recovering and purifying blast furnace gas, including a condenser box and a water tank located directly below the condenser box; a flow gas pipe with both ends passing through the outer ends of the condenser box is fixed inside the condenser box, a linkage box is fixed to the end face of the flow gas pipe located on the right side of the condenser box, a vertical linkage plate is set inside the linkage box, a circulating cooling pipe is wound around the surface of the flow gas pipe, a movable pipe is fixedly connected to the lower end face of the linkage box, an arc-shaped flexible rod is fixed to the left side of the linkage plate, a vertical rod inserted into the movable pipe is fixed to the lower end face of the flexible rod, and two sealing balls arranged symmetrically inside the movable pipe are fixed to the surface of the vertical rod inside the movable pipe.
[0007] The present invention is further configured such that both ends of the circulating cooling pipe pass through the lower side wall of the condenser, and the left end of the circulating cooling pipe is connected to the water outlet of the water tank.
[0008] The present invention is further configured such that an assembly pipe is fixed to the side wall of the movable pipe located between the two sealing balls and communicates with its interior, and the assembly pipe is connected to the right port of the circulating cold pipe.
[0009] The present invention is further configured such that a floating pipe with a diameter larger than that of the movable pipe is fixed to the lower end face of the movable pipe, and a connecting pipe with the same diameter as the movable pipe is fixed to the lower end face of the floating pipe, and the connecting pipe is connected to the water inlet of the water tank.
[0010] The present invention is further configured such that a converging pipe connected to the interior of the lower side wall of the condenser is fixedly connected to the middle part of the lower side wall of the condenser, and a linkage pipe connected to the converging pipe is fixedly connected to the upper end face of the water tank.
[0011] The present invention is further configured such that a discharge pipe is fixedly connected to the lower part of the front end face of the water tank, and an addition pipe is fixedly connected to the upper end face of the water tank located to the left of the linkage pipe.
[0012] The present invention is further configured such that a bending spring is fixed on the left side wall of the linkage plate, which abuts against the inner bottom surface of the linkage box, and the bending spring is sleeved on the flexible rod.
[0013] The present invention is further provided that the lower part of the front and rear side walls of the linkage plate is fixed with a shaft rod that is rotatably connected to the inner side wall of the linkage box.
[0014] This utility model has the following beneficial effects:
[0015] 1. When the water pump inside the water tank draws the coolant into the circulating cooling pipe, the coolant flows directly from the assembly pipe into the movable pipe, and then flows from the movable pipe into the water tank through the floating pipe and connecting pipe, thereby achieving circulating cooling. At the same time, the coolant is cooled by the radiator installed inside the water tank.
[0016] 2. When the gas enters the linkage box, it pushes the linkage plate, causing the plate to rotate within the linkage box. This rotation compresses the flexible rod into the movable tube, controlling the vertical rod to move downwards within the movable tube. Simultaneously, it moves the sealing ball at the bottom into the floating tube, allowing the assembly tube to connect with the interior of the floating tube through the movable tube. This ensures that the coolant can circulate according to the gas flow, achieving synchronous alternation between the gas and the coolant. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figures 1 to 5 This utility model is a water-cooling device for recovering and purifying blast furnace gas. By spirally winding the circulating cooling pipe 204 around the flowing gas pipe 3, the gas can be rapidly cooled. At the same time, the linkage plate 4 and the gas flow direction are coordinated to ensure that the coolant can circulate according to the gas entering, so as to realize the synchronous alternation of gas and coolant.
[0028] Specifically, the system includes a condenser box 1 and a water tank 2 located directly below the condenser box 1. Inside the condenser box 1, a flow pipe 3 is fixed, extending through both ends of the condenser box 1. A linkage box 301 is fixed to the end face of the flow pipe 3 on the right side of the condenser box 1. Inside the linkage box 301, a vertical linkage plate 4 is installed. A circulating cooling pipe 204 is wound around the surface of the flow pipe 3. A movable pipe 302 is fixedly connected to the lower end face of the linkage box 301. An arc-shaped flexible rod 401 is fixed to the left side of the linkage plate 4. The flexible rod 401... A vertical rod 403 is fixed to the lower end face and inserted into the inside of the movable tube 302. Two sealing balls 404 are fixed on the surface inside the movable tube 302 at the vertical rod 403. The two ends of the circulating cold pipe 204 pass through the lower side wall of the condenser box 1, and the left end of the circulating cold pipe 204 is connected to the outlet of the water tank 2. An assembly pipe 305 is fixed to the side wall of the movable tube 302 located between the two sealing balls 404 and is connected to the inside of the assembly pipe 305. The assembly pipe 305 is connected to the right end of the circulating cold pipe 204.
[0029] The operation process of this embodiment is as follows: Using the above-described structure, the left end face of the flowing gas pipe 3 is connected to the gas inlet of the electric arc furnace. Therefore, when the gas enters the interior of the linkage box 301, the gas pushes the linkage plate 4, causing the linkage plate 4 to rotate within the linkage box 301. This compresses the flexible rod 401 into the movable tube 302, controlling the vertical rod 403 to move downwards within the movable tube 302. Simultaneously, the sealing ball 404 at the bottom moves into the floating tube 303, thereby allowing the assembly tube 30... 5. The internal connection between the movable pipe 302 and the floating pipe 303 is made. When the water pump inside the water tank 2 draws the coolant into the circulating cooling pipe 204, the coolant is blocked by the sealing ball 404 located above, so that the coolant flows directly from the assembly pipe 305 into the movable pipe 302, and then flows from the movable pipe 302 into the water tank 2 through the floating pipe 303 and the connecting pipe 304, thereby realizing the circulating cooling work. At the same time, the coolant is cooled by the radiator installed inside the water tank 2.
[0030] Example 2
[0031] Please see Figure 3 and Figure 4 Based on Example 1, by using the bending spring 402 to reset the linkage plate 4, the sealing ball 404 can be guaranteed to reset autonomously.
[0032] Specifically, a floating pipe 303 with a diameter larger than that of the movable pipe 302 is fixed to the lower end face of the movable pipe 302. A connecting pipe 304 with the same diameter as the movable pipe 302 is fixed to the lower end face of the floating pipe 303, and the connecting pipe 304 is connected to the water inlet of the water tank 2. A bending spring 402 that abuts against the inner bottom surface of the linkage box 301 is fixed to the left side wall of the linkage plate 4, and the bending spring 402 is sleeved on the flexible rod 401. A shaft 406 that is rotatably connected to the inner side wall of the linkage box 301 is fixed to the lower part of the front and rear side walls of the linkage plate 4.
[0033] The operation process of this embodiment is as follows: When the linkage plate 4 rotates inside the linkage box 301 via the shaft 406, the linkage plate 4 will compress the bending spring 402. Therefore, when the gas stops entering the flow pipe 3, the bending spring 402 will push the linkage plate 4 to reset and rotate, thereby resetting the linkage plate 4. In this way, the sealing ball 404 will be reset via the soft rod 401 and the vertical rod 403, thereby causing the assembly pipe 305 to disconnect from the floating pipe 303 again.
[0034] Example 3
[0035] Please see Figure 2 and Figure 3 Based on Example 1, the use of the linkage pipe 203 allows the condensed liquid droplets to flow back.
[0036] Specifically, a converging pipe 101 connected to the interior is fixed in the middle of the lower side wall of the condenser box 1, a linkage pipe 203 connected to the converging pipe 101 is fixed in the upper end face of the water tank 2, a discharge pipe 201 is fixed in the lower part of the front end face of the water tank 2, and an addition pipe 202 is fixed in the upper end face of the water tank 2 located to the left of the linkage pipe 203.
[0037] The operation process of this embodiment is as follows: through the use of the linkage pipe 203, the liquid droplets condensed in the condenser box 1 will flow back to the water tank 2 from the linkage pipe 203. At the same time, through the use of the addition pipe 202, coolant is added to the inside of the water tank 2, and through the use of the discharge pipe 201, dirt inside the water tank 2 is easily discharged.
