Description

Technical Field

[0001] The present invention relates to the field of steelmaking, and particularly to a water replenishing device for the shell water of a continuous casting electromagnetic stirrer. Background Art

[0002] During steelmaking, circulating water is constantly required in the shell of the continuous casting electromagnetic stirrer to cool the equipment. Since ordinary equipment water is prone to scaling and has poor cooling effect, only expensive pure water can be used. Because there are many equipment used in the steelmaking process and many equipment need to be cooled, the existing entire circulating water system is shared with the above-mentioned numerous other equipment in a cycle, rather than being exclusively used by the continuous casting electromagnetic stirrer. Over time or when the water treatment effect deteriorates, the purity of the water will decrease, and the entire water system will scale. In particular, scaling in the shell of the electromagnetic stirrer will cause the cooling effect of the electromagnetic stirrer shell water system to deteriorate. The specific impacts are as follows: 1. It will reduce the service life of the equipment, and the maintenance and repair costs will increase significantly; 2. There is a great risk of electric leakage due to water leakage in the shell of the electromagnetic stirrer; 3. It will affect normal production and product quality. In addition, since circulating water will be lost or replaced during use, a large amount of pure water needs to be purchased externally, which also greatly increases the cost. Therefore, it is very necessary to design a device that does not share an independent cycle and can replenish clean water by itself. Summary of the Invention

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below. The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] A water replenishing device for the shell of a continuous casting electromagnetic stirrer, comprising a water supply and circulation system and a water replenishing system. The water supply and circulation system includes a main water tank 1, a return water pipe 2, a water supply pipe 3, a booster pump 6 and a cooling device 4. The water inlet and outlet of the main water tank are respectively connected to the water outlet and inlet of the shell of the electromagnetic stirrer 5 through the return water pipe and the water supply pipe. The cooling device is arranged on the return water pipe, so that the water flowing back through the return water pipe is cooled by the cooling device and then flows back to the main water tank. The booster pump is arranged on the water supply pipe, so that the water in the main water tank is pressurized by the booster pump and sent into the shell of the electromagnetic stirrer 5. The water replenishing system includes a waste heat boiler 7, a water replenishing pipeline and an emergency water replenishing tank 9. The waste heat boiler, the emergency water replenishing tank 9 and the main water tank are sequentially connected through the water replenishing pipeline, so that the distilled water generated by the waste heat boiler is stored in the emergency water replenishing tank through the water replenishing pipeline and then transported to the main water tank through the water replenishing pipeline when needed.

[0026] The water supply and circulation system of this application only supplies water to the shell of the electromagnetic stirrer, and no longer supplies circulating water to other equipment for cooling and recycling, so as to ensure the purity of water as much as possible to ensure the cooling effect of the water system of the electromagnetic stirrer, improve the service life of the equipment, reduce the maintenance and repair costs, and improve the production effect and product quality. In addition, a large amount of heat is generated during the steelmaking process. In this application, these heats are sent into the waste heat boiler device through the flue, and distilled water is generated in the waste heat boiler by using these heats. Then, these distilled waters are collected and stored in the emergency water replenishing tank and can be used to replenish the main water tank at any time. Using the waste heat of steelmaking to produce distilled water by itself instead of purchasing pure water externally not only makes full use of the surplus energy of the steel plant, but also saves costs, and at the same time ensures that the purity of water meets the long-term and efficient use requirements of the electromagnetic stirrer for cooling.

[0027] Embodiment 2:

[0028] The difference from the above embodiment is that a distilled water tank 8 is arranged between the waste heat boiler and the emergency water replenishing tank through a water replenishing pipeline. The distilled water can be collected and reserved through the distilled water tank. When the waste heat boiler and the electromagnetic stirrer are arranged at a long distance, the distilled water in the distilled water tank can be transported to the vicinity of the emergency water replenishing tank through a transfer water tank for water replenishment. The distilled water between the distilled water tank and the emergency water replenishing tank is transported through an independently transportable transfer water tank 81. A booster pump is also arranged on the water replenishing pipeline between the transfer water tank and the emergency water replenishing tank. The water in the distilled water tank can be pumped into the transfer water tank as required, and then the transfer water tank is transported to the required equipment for water supply. Of course, the distilled water tank of this application can also directly supply water to the emergency water replenishing tank through the water replenishing pipeline and the switches and booster pumps on the pipeline. The distilled water of this application can not only provide relatively pure water to the shell of the electromagnetic stirrer, but also supply water to other equipment in the factory, greatly saving the procurement cost and at the same time recovering the surplus energy well.

[0029] Example 3:

[0030] The difference from the above embodiments is that the cooling device is a plate heat exchanger. On the return water pipe, there are respectively provided switching valves 11 corresponding to at least the inlet and outlet of the cooling device, the water inlet of the main water tank, and the water outlet of the housing of the electromagnetic stirrer 5. A float valve 12 is provided in the main water tank. On the water supply pipe, there are respectively provided switching valves corresponding to at least the water supply outlet of the main water tank, the inlet and / or outlet of the booster pump, and the water inlet of the housing of the electromagnetic stirrer 5. A liquid level transmitter 111 can also be arranged in the main water tank. The cooperation between the float valve and the liquid level transmitter can better monitor the water level in the main water tank for timely water replenishment. The high-temperature water flowing back from the electromagnetic stirrer can be cooled by the cooling device and then sent back to the main water tank, so as to be recycled to cool the electromagnetic stirrer.

[0031] Example 4:

[0032] The difference from the above embodiments is that two booster pumps are connected in parallel on the water supply pipe. The two booster pumps can be turned on simultaneously or one can be turned on during use while the other can be used as a standby. A filter 10 is provided on the water supply pipe between the booster pump and the electromagnetic stirrer 5. The filter is a bag filter. Since the pipeline is long, the water may carry some scale after flowing through various devices and pipelines in the process, so the water sent into the housing of the electromagnetic stirrer is filtered to improve the purity of the water and then sent into the housing of the electromagnetic stirrer, thereby improving the service life of the electromagnetic stirrer. A filter selection switch 101 is connected in parallel with the filter on the water supply pipe. Switching valves are provided at the water outlet and / or water inlet of the filter. The filter can be selectively used. When it is not needed, the switch on the filter pipe can be closed and the parallel selection switch can be opened, so that the water can be directly sent into the housing of the electromagnetic stirrer without passing through the filter.

[0033] Example 5:

[0034] The difference from the above embodiment is that the cooling device is a water curtain cooling chamber, which includes an air inlet 41, an air outlet 42, a main water pipe 43, branch pipes 44, a water outlet component and a water collecting port 401. The air inlet and the air outlet are located on both sides of the water curtain cooling chamber. The main water pipe passes through the water curtain cooling chamber and its axis is perpendicular to the air path formed between the air inlet and the air outlet. A plurality of branch pipes are evenly distributed on the main water pipe. The water outlet component includes a bottom guide plate 45 and a top clamping plate 46 provided on the chamber wall plate of the water curtain cooling chamber. The main water pipe and the branch pipes are arranged between the bottom guide plate and the top clamping plate. Thus, the water coming from the main water pipe enters the plurality of branch pipes to evenly disperse the water for the first step. And there are water flow ports 47 at the free ends of the bottom guide plate and the top clamping plate. The cooling water collected by the water collecting port can flow back into the return pipe 2. Since the electromagnetic stirrer has a relatively high temperature, to ensure that the water temperature sent back to the main water tank and the outer shell of the electromagnetic stirrer meets the cooling requirements and can be recycled continuously and quickly, the present application also designs a water curtain cooling chamber. By sending the recycled water into the water curtain cooling chamber to be dispersed and evenly opened to form a water curtain or a water column or a thin water flow, and then blowing the water curtain or the water column or the thin water flow with the cold air or natural wind sent through the air inlet, the effect of rapid cooling can be achieved. The water cooled by the wind then returns from the water collecting port into the return water pipeline and is sent to the main water tank.

[0035] Embodiment Six:

[0036] The difference from the above embodiment is that the bottom guide plate and the top clamping plate are inclined, and the long strip-shaped water flow port is located at the lower end of the bottom guide plate and faces the air inlet. There is a pipe accommodating cavity 48 at the upper part and a water equalizing cavity 49 at the lower part between the bottom guide plate and the top clamping plate. The distance between the bottom guide plate and the top clamping plate in the area corresponding to the pipe accommodating cavity is greater than that in the area corresponding to the water equalizing cavity. The upper end of the bottom guide plate extends upward in an arc to form a water dispersing plate 451, and the water outlet of the branch pipe faces the water dispersing plate. The recycled water sent from the main water pipe is evenly dispersed by the branch pipes for the first step and then sprayed onto the water dispersing plate for the second step of dispersion and flow velocity reduction, so as to disperse the recycled water. After the recycled water is dispersed, it flows evenly out from the water flow port along the bottom guide plate, so as to fully disperse the recycled water and then can have a large-area contact with the air sent through the air inlet, improving the cooling efficiency. The bottom guide plate is inclined, and the inclination angle is designed to be close to horizontal, so as to further reduce the flow velocity and evenly disperse the water at the same time. The water outlet of the branch pipe faces the water dispersing plate, that is, the water outlet of the branch pipe is back to the water flow port, so as to lengthen the flow path of the recycled water and fully disperse it in the pipe accommodating cavity and the water equalizing cavity, ensuring stable and even dispersion of the water flow. The water flow port facing the air inlet enables full contact between the water and the air for heat exchange. At the same time, it can also extend the distance from the water falling on the bottom plate of the water curtain cooling chamber to the water collecting port, thus prolonging the flowing time of the water on the bottom plate and further prolonging the heat exchange time of the water flow on the bottom plate, further improving the cooling efficiency.

[0037] In addition, a sandwich layer 452 can be provided on the lower surface of the bottom plate. Cooling medium such as cold water is continuously fed into the sandwich layer to cool the bottom plate in real time, so that the return water flowing on the bottom plate can be cooled from above and below by the wind and the cooling medium, greatly improving the cooling efficiency. In this application, a semiconductor can also be provided at the bottom of the bottom plate with the refrigerating surface of the semiconductor facing the bottom plate to cool the bottom plate.

[0038] Embodiment Seven:

[0039] The difference from the above embodiment is that the water distribution cavity includes a gradually narrowing current collecting section 491 connecting to the container pipe cavity in the upper section and a uniform flow section 492 with a fixed vertical distance in the lower section. Since the container pipe cavity is large while the uniform flow section is narrow, the gradually narrowing current collecting section serves to buffer and collect the water flow and sort out the water flow, while the uniform flow section narrows and evenly divides the collected water flow to achieve a uniform opening effect, so as to evenly spread out the water flow and ensure that the water flow spreading ports at the water outlet are fully in contact with the cold air for heat exchange, thereby improving the cooling efficiency of the return water.

[0040] Embodiment Eight:

[0041] The difference from the above embodiment is that the main water pipe 43, the branch pipe 44, and the water outlet component form a set of water outlet assemblies, and at least one set of the water outlet assemblies is provided in the water curtain cooling chamber. To further improve the cooling efficiency, multiple sets of water outlet assemblies can be provided in the water curtain cooling chamber. The air intake volume per unit time can cool more flowing water. On the one hand, it saves costs, on the other hand, it makes full use of the cooling air efficiency of the air inlet blower, and also makes full use of the indoor space in the water curtain cooling chamber. Each set of water outlet assemblies can be arranged in sequence along the direction of the wind.

[0042] A plurality of water leakage holes 453 are formed on the bottom guide plate. The bottom guide plate can be densely provided with some water leakage holes. While the main water flows through the container pipe cavity 48 and the water distribution cavity 49 and evenly disperses and flows out from the water outlet, part of the water flow can leak out from the water leakage holes, thereby evenly spreading and dispersing the water flow in multiple ways and improving the cooling efficiency. The upper edges of the upper ends of the bottom guide plate and the top guide plate are connected to the top wall of the water curtain cooling chamber, or the upper edges of the upper ends of the bottom guide plate and the top guide plate are bent towards each other, so as to controllably guide the water flow into the container pipe cavity and the water distribution cavity to prevent it from splashing out of the container pipe cavity quickly and resulting in too fast a flow rate and insufficient heat exchange.

[0043] Embodiment Nine:

[0044] The difference from the above embodiment is that the bottom plate of the water curtain cooling chamber is a slow-flow plate 402 that is gradually inclined downward in the direction from the air inlet to the water collection port and is wavy. A slow-flow mesh plate 403 is also vertically installed between the water outlet assembly and the air outlet. Through the inclined slow-flow plate, it can not only ensure that the water flows towards the water collection port, but also further reduce the flow velocity of the water on the bottom plate while increasing the spreading surface of the water, so that the water flowing down from the water outlet assembly spreads out on the bottom plate and is buffered by the slow-flow plate and the contact surface is increased, so that it can fully exchange heat with the cold air sent in from the air inlet, thereby performing secondary re-cooling on the water flowing onto the bottom plate. The first cooling is the process from the water outlet of the water outlet assembly to the bottom plate. In addition, the setting of the slow-flow mesh plate makes the flowing water blown up by the wind hit the mesh plate. On the one hand, the water is further broken up, and on the other hand, while allowing air to pass through, most of the water can be intercepted and flow downward and then flow from the bottom plate to the water collection port, thereby increasing the flow path of the water in the water curtain cooling chamber to facilitate more sufficient heat exchange with the cold air. Prevent the water flow from directly hitting the wall plate with the air outlet of the water curtain cooling chamber in a sheet and flowing directly downward to the water collection port. The slow-flow mesh plates can also be multiple arranged in sequence along the air flow path.
