Description

Technical Field

[0001] The utility model relates to the technical field of power generation blast furnaces, in particular to a temperature control device for a power generation blast furnace. Background Art

[0002] A blast furnace is a coal-fired or gas-fired boiler used for power generation. It generates high-temperature fuel gas by burning fuel, driving a steam turbine that in turn drives a generator to generate electricity. Blast furnaces are a common form of power generation in current power systems, offering high energy conversion efficiency and stable power output. While operating, the temperature of a blast furnace must be controlled within a reasonable range to ensure equipment safety and production quality. However, existing technologies have the following deficiencies when used:

[0003] When a power-generating blast furnace is in continuous operation, the temperature inside the furnace body will continue to rise. When the internal temperature is too high, it is difficult to quickly cool down the inside of the power-generating blast furnace. The excessively high temperature inside the furnace body may damage the furnace body structure, which has certain disadvantages in actual operation.

[0004] Therefore, a temperature control device for a power generation blast furnace is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to address the current problem that when a power generation blast furnace is continuously running, the temperature inside the furnace body will continue to rise. When the internal temperature is too high, it is difficult to quickly cool down the inside of the power generation blast furnace. The excessively high temperature inside the furnace body may damage the furnace body structure, which leads to certain disadvantages in actual operation.

[0006] In order to achieve the above objectives, the present invention provides the following technical solutions:

[0007] A temperature control device for a power generation blast furnace is provided to improve the above problems.

[0008] The specific application is as follows:

[0009] A temperature control device for a power generation blast furnace comprises a power generation blast furnace body, a temperature sensor and a temperature display are installed on the front of the power generation blast furnace body, a base is provided on one side of the power generation blast furnace body, a mounting frame and a box filled with coolant are provided on the top of the base, an air pump is fixedly connected to the top of the mounting frame, an air inlet of the air pump is fixedly connected to an air inlet pipe, an air outlet of the air pump is fixedly connected to a first air duct running through the box, an end of the first air duct away from the air pump is fixedly connected to a second air duct, a plurality of air outlet pipes arranged evenly and equidistantly are fixedly connected to the second air duct, and an end of the air outlet pipe away from the second air duct is located in the power generation blast furnace body.

[0010] As a preferred technical solution of the present application, a ball valve is installed on the first air duct.

[0011] As a preferred technical solution of the present application, a top cover is threadedly connected to the top of the box body.

[0012] As a preferred technical solution of the present application, symmetrically distributed sealing gaskets are fixedly connected to the box body, and the sealing gaskets are sleeved on the first air duct.

[0013] As a preferred technical solution of the present application, the first air duct is fixedly connected to the box body.

[0014] As a preferred technical solution of the present application, the temperature sensor and the temperature display are electrically connected.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the scheme of this application:

[0017] 1. When the temperature inside the power generation blast furnace body is too high, the air pump is started to draw in outside air through the air inlet pipe. Since part of the first air duct is always located in the box filled with coolant, the coolant will always be in contact with the outer surface of the first air duct, so that the first air duct is at a lower temperature. When the air flow is transported in the first air duct, the air flow will be cooled to make the temperature of the air flow lower. Finally, after the air flow passes through the second air duct, the cold air is discharged into the power generation blast furnace body through multiple evenly arranged air outlet pipes, thereby quickly cooling the inside of the power generation blast furnace body, solving the problem in the prior art that when the power generation blast furnace is continuously running, the temperature inside the furnace body will continue to rise, and when its internal temperature is too high, it is difficult to quickly cool the inside of the power generation blast furnace, and the excessively high temperature inside the furnace body may damage the furnace body structure, which has certain disadvantages in actual operation.

[0018] 2. Through the set temperature sensor and temperature display, the temperature inside the power generation blast furnace can be detected by the temperature sensor. The temperature sensor transmits the electrical signal to the temperature display, and the temperature display displays the detected temperature value, which is convenient for the staff to observe the detected temperature value.

Since part of the first air duct 9 is always located in the box 6 filled with coolant, the coolant will always be in contact with the outer surface of the first air duct 9, so that the first air duct 9 is at a lower temperature. When the airflow is transported in the first air duct 9, the airflow will be cooled, so that the temperature of the airflow is lower. The second air duct 10 is fixedly connected to a plurality of evenly and equidistantly arranged air outlet pipes 11, and the end of the air outlet pipe 11 away from the second air duct 10 is located in the power generation blast furnace body 1. Finally, after the airflow passes through the second air duct 10, the cold air is discharged into the power generation blast furnace body 1 through a plurality of evenly arranged air outlet pipes 11, thereby quickly cooling the inside of the power generation blast furnace body 1.

[0033] like Figure 2 and Figure 3 As shown, a ball valve 12 is installed on the first air guide pipe 9. Before starting the air pump 7, the ball valve 12 is opened first to facilitate the delivery of cold air.

[0034] like Figure 2 As shown, a top cover 13 is threadedly connected to the top of the box body 6. By rotating the top cover 13, it can be removed from the box body 6 to facilitate the subsequent injection of coolant into the box body 6.

[0038] Specifically, when the temperature control equipment of the power generation blast furnace is in use: when the power generation blast furnace body 1 is in operation, the temperature inside it is detected by the temperature sensor 2, and the temperature sensor 2 transmits the electrical signal to the temperature display 3, and the detected temperature value is displayed by the temperature display 3, so that the staff can observe the detected temperature value. When the temperature value displayed by the temperature display 3 is too high, the air pump 7 is started to suck in external air through the air inlet pipe 8. Since part of the first air duct 9 is always located in the box 6 filled with coolant, the coolant will always be in contact with the outer surface of the first air duct 9, so that the first air duct 9 is at a lower temperature. When the air flow is transported in the first air duct 9, the air flow will be cooled, so that the temperature of the air flow is lower. Finally, after the air flow passes through the second air duct 10, the cold air is discharged into the power generation blast furnace body 1 through a plurality of evenly arranged air outlet pipes 11, thereby quickly cooling the inside of the power generation blast furnace body 1.
