Description

Technical Field

[0001] This application relates to the technical field of cooling equipment, and in particular to a vertical furnace water beam water system. Background Technology

[0002] In existing technologies, the working status of small water beams is generally judged by manual observation by operators. Since the small water beams bear weight during use, if the internal cooling water flow of a small water beam is too low, it will cause the temperature of the small water beam to be too high, which will cause the small water beam to bend. By the time the abnormal shape and position of the small water beam is observed by manual observation, it is already too late. The response speed to abnormal working status of small water beams is slow and the troubleshooting is difficult. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1 and attached Figure 2 This application will be described in further detail.

[0020] To better understand the technical solutions presented in the embodiments of this application, a brief introduction to the existing small water beam water system will be given first.

[0021] The second-phase vertical shaft furnace in the pelletizing lime workshop of the ironmaking plant is currently using one small water beam system online. Its main component is a seamless θ168*25 pipe made of 20G steel. This water beam is primarily responsible for fixing the grate bars of the furnace drying bed, ensuring the entire drying bed does not sag while meeting the requirements for green pellet baking. The water beam is routinely cooled internally by a water pump from a water tank to the top water beam's inlet pipe, which connects to the small water beam's internal pipes for internal cooling. After passing through the pipes, the water returns to the cooling tower's water tank via a return pipe valve for further cooling and recycling. Steam is generated during this process and needs to be continuously pumped out and replenished.

[0022] In existing technologies, the working status of the small water beam is generally judged by the operator's manual observation. Since the small water beam bears weight during use, if the internal cooling water flow of a small water beam is too low, it will cause the small water beam to overheat, which will cause the small water beam to bend. By the time the abnormal shape and position of the small water beam is observed by manual observation, it is already too late, and the reaction speed to the abnormal working status of the small water beam is slow.

[0023] To address the aforementioned technical problems, this application provides a vertical shaft furnace water beam system, including an installation body 1, a cooling tower 2 for cooling return water, a water distribution tank 3 for storing supply water, a main water supply pipe 4, a main return water pipe 5, and several small water beams 6.

[0024] A water pump 7 is installed in the water distribution tank 3. One end of the main water supply pipe is connected to the outlet of the water pump 7. Several branch water supply pipes 8 are connected to the main water supply pipe. The several branch water supply pipes 8 are respectively connected to the inlet of several small water beams 6.

[0025] The outlet of the main return water pipe 5 extends into the cooling tower 2. Several branch return water pipes 9 are connected to the main return water pipe 5. The inlets of the several branch return water pipes 9 are respectively connected to the outlets of several small water beams 6.

[0026] Several small water beams 6 are installed on the mounting body 1. The small water beams 6 are independent of each other. Electromagnetic flow meters 10 for measuring the water flow inside the small water beams 6 are installed at the inlet and outlet of the small water beams 6.

[0027] The following section will provide further details based on specific usage scenarios.

[0028] In use, several small water beams 6 are installed on the mounting body 1 to provide support for the drying bed grate bars. The water pump 7 in the water distribution tank 3 draws water from the water distribution tank 3. The water drawn by the water pump 7 is distributed to several small water beams 6 through the main water supply pipe and the branch water supply pipe 8. The water entering the small water beams 6 can maintain the temperature of the continuously heated small water beams 6, thereby maintaining the shape of the small water beams 6 and preventing the small water beams 6 from bending due to overheating.

[0029] The cooling water entering the small water beam 6 exits through the outlet of the small water beam 6 after passing through the small water beam 6. The heated cooling water and high-temperature steam leaving the small water beam 6 enter the cooling tower 2 through the branch return water pipe 9 installed on the small water beam 6 for cooling. The cooled water then re-enters the water distribution pool 3 to form a water circulation.

[0030] In this embodiment, the multiple small water beams 6 are independent of each other, and each small water beam 6 is equipped with an electromagnetic flow meter 10 at its inlet and outlet to detect the internal cooling water flow rate. The operator can check whether the working status of the small water beam 6 is abnormal by checking the values ​​of the electromagnetic flow meters 10 at the inlet and outlet of the multiple small water beams 6.

[0031] When the reading of the electromagnetic flowmeter 10 at the inlet of the small water beam 6 is normal, but the reading of the electromagnetic flowmeter 10 at the outlet is low, it can be considered that the small water beam 6 is under a large working load and receives a lot of heat, so it is necessary to increase the cooling water inflow of the small water beam 6.

[0032] When the reading of the electromagnetic flowmeter 10 at the inlet of the small water beam 6 is low, or the reading of the electromagnetic flowmeter 10 at the outlet is low, it can be considered that the small water beam 6 is malfunctioning, or that the cooling water supplied in the main water supply pipe is insufficient. Operators need to check the status of the small water beam 6 and the main cooling water supply.

[0033] The electromagnetic flowmeters 10 installed on each small water beam 6 independently measure the cooling water flow rate inside each small water beam 6. In this way, the operator can quickly understand the working status of the small water beam 6 by reading the electromagnetic flowmeters 10 on each small water beam 6, which significantly improves the efficiency of the operator in checking the status of the small water beam 6, as well as the operator's reaction time when problems occur in the operation of the small water beam 6.

[0034] In this embodiment of the application, the system also includes a return pipe 11. The inlet and outlet of the return pipe 11 are connected to the cooling tower 2 and the water distribution pool 3, respectively. The high-temperature cooling water discharged through the small water beam 6 and the high-temperature water discharged into the cooling tower 2 are cooled in the cooling tower 2. The water cooled in the cooling tower 2 and the water that becomes liquid again will flow back to the water distribution pool 3 through the return pipe 11 to form a water cycle.

[0035] In this embodiment, electromagnetic flow meters 10 can be installed on both the main return water pipe 5 and the main supply water pipe 4. When the readings of the branch supply water pipe 8 and the branch return water pipe 9 are abnormal, the operator can obtain the internal liquid flow of the main return water pipe 5 and the main supply water pipe 4 by observing the electromagnetic flow meters 10 installed on the main return water pipe 5 and the main supply water pipe 4, thereby determining whether the specific small water beam 6 has malfunctioned.

[0036] In this embodiment, the system also includes a control console. The control console is connected via signal line or wireless signal to the electromagnetic flowmeter 10 installed on the main return water pipe 5, the main supply water pipe 4, and the small water beam 6. Operators can quickly view the flow rate display of the entire system by checking the control console to quickly assess the system's operating status. The control console may contain one or more integrated circuits, such as one or more application-specific integrated circuits (ASICs), one or more digital signal processors (DSPs), one or more field-programmable gate arrays (FPGAs), or a combination of at least two of these integrated circuit forms. Alternatively, it may contain one or more processing elements, which can be general-purpose processors, such as central processing units (CPUs) or other processors capable of calling programs. Furthermore, these units can be integrated together as a system-on-a-chip (SOC).

[0037] In this embodiment of the application, a valve 12 is also installed at the water outlet end of the small water beam 6 to control the opening and closing of the internal flow channel of the small water beam 6. The operator can independently control the opening and closing of each small water beam 6 through the valve 12, and can control the flow rate of the water inside the small water beam 6 by the opening and closing size of the valve 12, thereby controlling the residence time of the cooling water inside the small water beam 6 to adapt to different temperatures and working environments.

[0038] In this embodiment, the valve 12 on the small water beam 6 is located on the side of the electromagnetic flowmeter 10 on the small water beam 6 near the water inlet of the small water beam 6. The cooling water discharged from the small water beam 6 first passes through the valve 12 and then through the electromagnetic flowmeter 10. After the operator controls the water flow inside the small water beam 6 through the valve 12, he can still observe the flow rate of the controlled cooling water from the small water beam 6 through the electromagnetic flowmeter 10 to determine the working status of the small water beam 6.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
