Description

Technical Field

[0001] This application belongs to the field of blast furnace dehumidification technology, specifically relating to a blast furnace blast furnace dehumidification system. Background Technology

[0002] Blast dehumidification, as an energy-saving technology in metallurgy, has been gradually adopted by a large number of steel mills in China. However, in practical applications, due to the different humidity requirements of each blast furnace, each blower needs to be equipped with a separate refrigeration station for easy adjustment. This results in high investment costs for the blower dehumidification system. Furthermore, the dehumidification season lasts only a few months of the year, especially in northern steel mills where it typically lasts three months, leading to low utilization rates of the refrigeration units. If backup blowers are available, the utilization rate will be even lower. Although dehumidifying blowers have a significant effect on energy conservation in blast furnaces, the high cost and low utilization rate of building separate refrigeration stations for each blower hinder the willingness of most steel companies to construct dehumidifying blower systems.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] This utility model discloses a blast furnace blast dehumidification system, which can solve the technical problem of low utilization rate of refrigeration units in the prior art.

[0023] The technical solution of this application will be described in detail below through specific embodiments: See Figure 1 and Figure 2This application discloses a blast furnace blast dehumidification system, which includes a refrigeration component 100, a water supply pipe 200, a return water pipe 300, and multiple dehumidification components 400. The water supply pipe 200 is connected to the outlet of the refrigeration component 100. The return water pipe 300 is connected to the return water of the refrigeration component 100. All multiple dehumidification components 400 are connected to the refrigeration component 100. Each dehumidification component 400 includes a dehumidifier 410, a water supply regulating valve 420, and a return water shut-off valve 430. The inlet of each dehumidifier 410 is connected to the water supply pipe 200 through the water supply regulating valve 420, and the outlet of each dehumidifier 410 is connected to the return water pipe 300 through the return water shut-off valve 430. The dehumidifier 410 is provided with a first connection port 440 for connecting to the filter chamber and a second connection port 450 for connecting to the blower.

[0024] In traditional blast furnace dehumidification systems, due to the varying humidity requirements of different blast furnaces, a separate refrigeration station is required for each blower. This results in the purchase and installation of a large amount of refrigeration equipment, leading to high investment costs. Furthermore, in traditional systems, the dehumidification season is typically short, especially in northern steel plants where it may only last about three months, leaving the refrigeration units idle for most of the time with extremely low utilization. The blast furnace dehumidification system disclosed in this embodiment adopts a model where multiple dehumidification components 400 share a single refrigeration component 100, reducing the number of refrigeration units. Only one refrigeration component 100 is needed to meet the dehumidification needs of multiple units, significantly reducing equipment procurement and installation costs. By providing cooling for multiple dehumidification components 400, the refrigeration unit can operate continuously throughout the entire dehumidification season or even year-round, increasing the frequency and duration of refrigeration unit use, fully utilizing equipment performance, and improving resource utilization efficiency.

[0025] Setting up multiple refrigeration stations requires a significant amount of space to accommodate equipment, piping, and other facilities. This system centrally integrates 100 refrigeration units, reducing the equipment footprint. For steel plants with limited land resources, this effectively lowers space occupancy costs and also facilitates overall plant planning and layout optimization.

[0026] Multiple dehumidification units 400 operate in parallel, enabling simultaneous dehumidification of multiple blast furnace blast lines according to the actual needs of different blast furnaces, thus improving the overall dehumidification capacity. Furthermore, each dehumidification unit 400 is independently equipped with a water supply regulating valve 420 and a return water shut-off valve 430, allowing for flexible adjustment of the water supply as needed to ensure the dehumidifier 410 operates at its optimal state, further enhancing dehumidification efficiency.

[0027] In one embodiment, the refrigeration assembly 100 includes a refrigeration unit 110 and a chilled water pump 120. The two ends of the chilled water pump 120 are connected to the return water pipe 300 and the return water port of the refrigeration unit 110, respectively, and the outlet of the refrigeration unit 110 is connected to the supply water pipe 200.

[0028] The outlet of the chiller unit 110 is connected to the water supply pipe 200. The chilled water pump 120 draws return water from the return water pipe 300 back to the chiller unit 110, forming a complete circulation loop. The chilled water pump 120 serves as the power source for the refrigeration cycle, with its two ends connected to the return water pipe 300 and the return water outlet of the chiller unit 110, respectively. The operation of the chilled water pump 120 provides stable and sufficient power for the entire refrigeration cycle, ensuring smooth circulation of chilled water within the system. This allows the cooling capacity generated by the chiller unit 110 to be efficiently transferred to each dehumidification component 400, meeting the cooling capacity requirements of blast furnace blast dehumidification and effectively improving refrigeration efficiency.

[0029] During the refrigeration cycle, the operation of the refrigeration pump 120 helps to expel air from the system and prevent airlock. At the same time, a well-designed circulation system also helps to reduce the accumulation of impurities in the pipes, lowering the risk of pipe blockage and ensuring the long-term stable operation of the system.

[0030] In one embodiment, the refrigeration unit 110 is an electrically refrigerated refrigeration unit 110 or a lithium bromide refrigeration unit 110.

[0031] The electric chiller unit 110 features rapid start-up and flexible adjustment, enabling it to achieve the required cooling effect in a short time. It can also quickly adjust its cooling capacity according to the actual needs of blast furnace blast dehumidification. This makes it ideal for operating conditions requiring high cooling response speed and frequent load changes. For example, in blast furnace workshops with fast production paces and the need to flexibly adjust blast humidity according to different time periods and process requirements, the electric chiller unit 110 can quickly meet production demands. In regions with abundant power resources and relatively low electricity prices, the operating cost of the electric chiller unit 110 is low. Moreover, with the development of power technology, some regions have adopted peak-valley electricity pricing. The electric chiller unit 110 can increase its cooling capacity during off-peak hours, storing the cooling capacity and using it during peak hours, thereby reducing operating costs. Furthermore, the electric chiller unit 110 is technologically mature, with relatively simple equipment maintenance and low maintenance costs.

[0032] The lithium bromide chiller unit 110 can utilize low-grade heat energy, such as steam and hot water, as its driving energy source. In enterprises with abundant waste heat resources, such as steel plants generating their own waste heat steam, the lithium bromide chiller unit 110 can effectively utilize this waste heat for refrigeration, achieving cascaded energy utilization. This characteristic makes the lithium bromide chiller unit 110 suitable for scenarios with a stable waste heat supply and high energy-saving requirements. When enterprises have a large amount of inexpensive waste heat resources available for utilization, the operating cost advantage of the lithium bromide chiller unit 110 is significant. It does not require the consumption of large amounts of electricity, mainly utilizing waste heat to drive the refrigeration cycle, greatly reducing energy costs. For example, steel plants can use the residual steam after generating electricity from blast furnace gas waste heat as the heat source for the lithium bromide chiller unit 110, which improves energy utilization efficiency and reduces refrigeration costs.

[0033] In one embodiment, the chilled water pump 120 is a variable frequency pump. The demand for chilled water in the blast furnace dehumidification system is not constant under different time periods and production conditions. The variable frequency pump can adjust its speed in real time according to the actual load demand of the system, thereby precisely controlling the flow rate of the chilled water. When the system requires less cooling, the pump speed is reduced, decreasing the amount of chilled water delivered. This avoids the energy waste caused by a fixed frequency pump operating at high flow rates under low load, significantly reducing electricity consumption.

[0034] In another embodiment, the chilled water pump 120 consists of multiple pumps connected in parallel. When one or more pumps fail, the remaining pumps continue to supply chilled water to the system, ensuring that the blast furnace dehumidification system is not interrupted due to a single pump failure. For example, in a system with three chilled water pumps 120 connected in parallel, even if one pump fails suddenly, the remaining two pumps can still maintain a certain proportion of the cooling capacity, ensuring the continuity of blast furnace production and greatly improving the system's resilience.

[0035] The load on the blast furnace blast dehumidification system fluctuates with changes in the blast furnace's operating conditions and ambient temperature. Multiple parallel chilled water pumps (120) can be flexibly adjusted in number to meet the actual load requirements of the system. During low-load periods, only a few pumps need to be started to meet the cooling demand; while during high-load periods, all pumps can be started to provide sufficient chilled water flow, ensuring the system always operates at high efficiency.

[0036] In one embodiment, the blast furnace blast dehumidification system further includes a water supply tank 500, which is connected to a return water pipe 300.

[0037] During operation, the blast furnace blast dehumidification system experiences continuous chilled water loss due to evaporation and leakage. The makeup water tank 500, connected to the return water pipe 300, replenishes the system with water in a timely manner, ensuring a sufficient water level at all times. For example, in high-temperature summer conditions, the evaporation rate of chilled water is high; the makeup water tank 500 continuously replenishes the system, preventing problems such as pressure drop and reduced cooling effect due to insufficient water, thus ensuring the stable operation of the blast furnace blast dehumidification system.

[0038] In one embodiment, the outlet of the water supply tank 500 is connected to the return water pipe 300 after being connected in series with the water supply pump 510 and the pressure stabilizing tank 520.

[0039] The water replenishment pump 510 can precisely adjust the water replenishment volume according to the actual needs of the system. By monitoring parameters such as water level and pressure in the return water pipe 300, the control system can automatically control the start, stop, and speed of the water replenishment pump 510 to ensure that water is replenished to the system at an appropriate flow rate. For example, when the water volume of the system decreases due to evaporation or leakage, the water replenishment pump 510 can start in time and adjust to an appropriate flow rate to quickly replenish water, maintain the stability of the system's water volume, and avoid affecting the normal operation of the system due to insufficient water volume.

[0040] The continuous operation capability of the water replenishment pump 510 ensures the continuity of the water replenishment process. Compared with methods such as natural water replenishment relying on gravity, the water replenishment pump 510 can overcome certain resistance and stably deliver water to the system, ensuring the reliability of water replenishment even under high system pressure or long water replenishment distance.

[0041] In one embodiment, a plurality of cooling components 100 are provided, with the water outlet of each cooling component 100 connected to the water supply pipe 200 and the water return of each cooling component 100 connected to the water return pipe 300.

[0042] Multiple refrigeration units 100 operate in parallel. When one or more refrigeration units 100 fail, the remaining normally operating refrigeration units 100 can still continue to provide cooling to the system, ensuring that the blast furnace blast dehumidification system will not be completely interrupted due to the failure of individual components. For example, in a system consisting of three refrigeration units 100, even if one fails, the remaining two can still maintain a certain proportion of the system's cooling capacity, ensuring the continuity of blast furnace production and greatly reducing the risk of production stoppage due to equipment failure.

[0043] The cooling demand of the blast furnace dehumidification system fluctuates with changes in the blast furnace's operating conditions and ambient temperature. Multiple refrigeration components 100 can be flexibly adjusted in number to meet actual load requirements. During low-load periods, only a few refrigeration components 100 need to be activated to meet the cooling demand; while during high-load periods, all refrigeration components 100 can be activated to provide sufficient cooling capacity, ensuring the system always operates at high efficiency.

[0044] In one embodiment, the dehumidifier 410 includes a temperature and humidity sensor 460 and a controller. Both the temperature and humidity sensor 460 and the water supply regulating valve 420 are connected to the controller, which adjusts the opening of the water supply regulating valve 420 based on data from the temperature and humidity sensor 460. Furthermore, a chilled water pump is also electrically connected to the controller, which adjusts the water supply rate of the chilled water pump based on data from the temperature and humidity sensor 460.

[0045] The temperature and humidity sensor 460 can monitor the temperature and humidity data inside the dehumidifier 410 in real time and accurately, and feed this data back to the controller in a timely manner. Based on preset dehumidification target parameters, the controller compares the actual monitoring data and accurately calculates the required water supply adjustment, thereby adjusting the opening of the water supply regulating valve 420. This precise control method ensures that the dehumidifier 410 always operates under optimal temperature and humidity conditions, effectively removing moisture from the blower air, improving dehumidification efficiency, and keeping the humidity of the outlet air stably controlled within the ideal range.

[0046] In one embodiment, the dehumidifier 410 is provided with a condensate tank 470 and a condensate pump 480 at its bottom. The condensate tank 470 is used to collect and store the condensate inside the dehumidifier 410.

[0047] During the dehumidification process of blast furnace blast, a large amount of condensate is generated. This condensate is relatively low in temperature and relatively clean. Collected and stored in the condensate tank 470, it is then pumped by the condensate pump 480 into other structures for cooling, allowing the condensate to be reused as cooling water. This not only reduces the amount of fresh water used and lowers water consumption costs, but also aligns with the concept of sustainable development, improving the efficiency and effectiveness of water resource utilization for the enterprise.

[0048] Through the above embodiments, this application has the following beneficial effects or advantages: The blast furnace blast dehumidification system disclosed in this application adopts a design where multiple dehumidification components 400 share a single refrigeration component 100, avoiding the need for each blower to be equipped with a separate refrigeration station, greatly reducing the number of refrigeration equipment, thereby significantly reducing the system's investment costs and alleviating the economic burden on steel enterprises. Since multiple dehumidification components 400 share the refrigeration component 100, the refrigeration unit can be fully utilized throughout the entire dehumidification season or even the whole year, no longer limited by the usage time of a single blower, effectively improving the utilization rate of the refrigeration unit and reducing resource waste caused by equipment idleness. By setting a water supply regulating valve 420 and a return water shut-off valve 430 on each dehumidification component 400, and setting a temperature and humidity sensor 460 and a controller inside the dehumidifier 410, the water supply of each dehumidifier 410 can be precisely adjusted according to the different blast furnace blast humidity requirements, achieving flexible control of blast humidity and improving the dehumidification effect. The chilled water pump 120 employs a variable frequency pump or multiple pumps connected in parallel, allowing for adjustment of the pump's operating status according to the system's actual needs, achieving energy-saving operation. Simultaneously, the arrangement of multiple refrigeration components 100 can be flexibly adjusted according to the system's processing capacity requirements, further improving energy efficiency. The condensate tank 470 and condensate pump 480 located at the bottom of the dehumidifier 410 can recover the condensate generated during dehumidification and pump it into the return water pipe 300, achieving water resource recycling, reducing water waste, and meeting energy conservation and environmental protection requirements. The arrangement of multiple refrigeration components 100, each operating independently yet collaboratively, ensures system stability and reliability even if some components 100 fail, allowing others to continue operating and reducing the risk of production interruptions due to equipment failure.
