Description

Technical Field

[0001] This utility model relates to an air supply device, specifically to a ground-mounted high-temperature gas supply device. Background Technology

[0002] The existing smelting industry generates flue gas with temperatures as high as 400°C or higher during the production process. Such high-temperature flue gas needs to be cooled to below 120°C before being sent to dust removal equipment for emission.

[0003] In existing technologies, a fan is installed on one side of the cooling chamber. High-temperature flue gas is sent into the cooling chamber, and the fan blows air into the chamber to cool it down. The cooled gas is then discharged from the outlet of the cooling chamber. This technical solution has the following drawbacks: First, because the fan is directly connected to the cooling chamber, it not only generates significant vibration and noise but also makes maintenance inconvenient. Second, since the cooling chamber is generally installed outdoors, filter bags need to be replaced outdoors, making maintenance difficult due to weather conditions. Third, in existing technologies, the fan uses a direct blowing method to cool the interior of the cooling chamber, resulting in uneven airflow and significantly affecting the cooling effect of the high-temperature flue gas. Utility Model Content

[0004] The purpose of this invention is to provide a ground-mounted high-temperature gas delivery device that not only has less vibration and noise, but is also easy to maintain and provides more uniform cooling airflow, thereby improving the cooling effect.

[0005] To achieve the above objectives, the technical solution of this utility model is: a ground-mounted high-temperature gas supply device, the innovation of which lies in: including an air supply unit, an air inlet box, and an air outlet box.

[0006] The air supply unit includes a cold air inlet duct, a fan, and a cold air delivery duct. One end of the cold air inlet duct is connected to the air intake of the fan, and the air outlet of the fan is connected to one end of the cold air delivery duct. The other end of the cold air delivery duct is connected to an air inlet box. The air inlet box and the air outlet box are respectively located on both sides of the cooling chamber, and the air inlet box and the air outlet box are respectively connected to the two end openings of the filter element in the cooling chamber.

[0007] Under the action of the fan, the cooling air is drawn into the cold air delivery pipe through the cold air inlet pipe, and then sent into the filter element inside the cooling chamber through the air inlet box to cool the high-temperature gas flowing through the cooling chamber. Finally, the cooling air is discharged through the air outlet box.

[0008] In the above technical solution, a rain cap is provided at the air inlet at the other end of the cold air inlet pipe to prevent rainwater from entering, and a protective net is provided at the opening of the rain cap to prevent foreign objects from entering the interior of the cold air inlet pipe.

[0009] In the above technical solution, the cold air inlet pipe is also equipped with a cold air inlet electric butterfly valve for adjusting the cooling airflow.

[0010] In the above technical solution, a temperature sensor is installed on the cold air delivery pipe to monitor the temperature of the cooling air.

[0011] In the above technical solution, the air supply unit further includes a cold air circulation assembly, which includes a cold air circulation duct, a cold air circulation electric butterfly valve, and a cold air outlet electric butterfly valve. The two ends of the cold air circulation duct are respectively connected to an air outlet box and a cold air inlet pipe, and the cold air circulation duct is also equipped with a cold air circulation electric butterfly valve. The air outlet box is equipped with a cold air outlet electric butterfly valve at its outlet.

[0012] When the cooling air is directly discharged, the electric butterfly valve for cold air circulation is closed, and the electric butterfly valve for cold air outlet is open, allowing the cooling air to be discharged directly from the air outlet box.

[0013] When the cooling air is circulating, the electric butterfly valve for cooling air circulation is in the open state, and the electric butterfly valve for cooling air outlet is in the closed state. The cooling air flows into the cooling air inlet pipe through the cooling air circulation pipe to form a cooling air circulation.

[0014] In the above technical solution, both the cold air inlet pipe and the cold air delivery pipe are equipped with inspection doors for easy inspection and maintenance.

[0015] In the above technical solution, the interior of the air inlet box and the air outlet box are separated into two independent chambers by corresponding partitions. The cooling chamber is provided with an air inlet chamber and an air outlet chamber. The two independent chambers of the air inlet box are respectively connected to one side of the air inlet chamber and the air outlet chamber of the cooling chamber. The two independent chambers of the air outlet box are respectively connected to the other side of the air inlet chamber and the air outlet chamber of the cooling chamber. At the same time, each independent chamber of the air inlet box is equipped with a set of air supply units for cooling the air inlet chamber and the air outlet chamber of the cooling chamber.

[0016] In the above technical solution, the interior of the air inlet box and the air outlet box are separated into two independent chambers by corresponding partitions, and each independent chamber is equipped with an inspection door.

[0017] In the above technical solution, the air inlet box is provided with a flow equalization mesh plate, and the flow equalization mesh plate is located at the junction of the air inlet box and the cooling chamber.

[0019] The air supply unit includes a cold air inlet duct, a fan, and a cold air delivery duct. One end of the cold air inlet duct is connected to the air intake of the fan, and the air outlet of the fan is connected to one end of the cold air delivery duct. The other end of the cold air delivery duct is connected to an air inlet box. The air inlet box and the air outlet box are respectively located on both sides of the cooling chamber, and the air inlet box and the air outlet box are respectively connected to the two end openings of the filter element in the cooling chamber.

[0020] Under the action of the fan, cooling air is drawn into the cooling air delivery pipe through the cooling air inlet pipe, and then sent into the filter element inside the cooling chamber through the air inlet box to cool the high-temperature gas flowing through the cooling chamber. The cooling air is finally discharged through the air outlet box.

[0021] This invention installs the air supply unit on the ground and uses it in conjunction with a high-temperature gas cooling device, creating a ground-mounted structure. This replaces the existing technology where the fan is directly installed on one side of the cooling chamber of the cooling device. The advantages of this design are: First, it not only saves installation space but also facilitates maintenance. Second, it reduces the vibration of the entire system caused by the fan operation and avoids the problem of excessive noise caused by fan vibration. Third, the filter bag can be replaced at any time by entering the air inlet box, avoiding the inconvenience of maintenance operations due to weather conditions.

[0027] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but it is not limited thereto.

[0028] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a ground-mounted high-temperature gas supply device includes an air supply unit, an air inlet box 4, and an air outlet box 5.

[0029] The air supply unit includes a cold air inlet pipe 1, a fan 2, and a cold air delivery pipe 3. One end of the cold air inlet pipe 1 is connected to the air intake of the fan 2, and the air outlet of the fan 2 is connected to one end of the cold air delivery pipe 3. The other end of the cold air delivery pipe 3 is connected to an air inlet box 4. The air inlet box 4 and the air outlet box 5 are respectively located on both sides of the cooling chamber 100, and the air inlet box 4 and the air outlet box 5 are respectively connected to the two end openings of the filter element in the cooling chamber.

[0030] Under the action of the fan 2, the cooling air is drawn into the cold air delivery pipe 3 through the cold air inlet pipe 1, and then sent into the filter element inside the cooling chamber 100 through the air inlet box 4 to cool the high temperature gas flowing through the cooling chamber. Finally, the cooling air is discharged through the air outlet box 5.

[0031] Furthermore, such as Figure 1 , 2 As shown in Figure 4, in order to prevent rainwater from entering the cold air inlet pipe and affecting the overall operational reliability of the equipment, and to prevent foreign objects from entering, a rain cap 6 is provided at the air inlet at the other end of the cold air inlet pipe 1 to prevent rainwater from entering, and a protective net is also provided at the opening of the rain cap 6 to prevent foreign objects from entering the interior of the cold air inlet pipe 1.

[0032] Furthermore, such as Figure 1 , 2 As shown in Figure 4, in order to achieve cooling airflow regulation, more flexibly adjust the cooling intensity, and improve the cooling effect, the cold air inlet pipe 1 is also equipped with a cold air inlet electric butterfly valve 7 for regulating the cooling airflow.

[0033] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, in order to obtain the real-time temperature of the cooling air in a timely manner and ensure the cooling capacity of the high-temperature flue gas, a temperature sensor 8 for monitoring the temperature of the cooling air is installed on the cold air delivery pipe 3.

[0034] Furthermore, such as Figure 1 , 2 As shown, in order to achieve the circulating delivery of cooling air, making it more energy-efficient and environmentally friendly, and enabling the cooling air to both circulate and be directly exhausted as needed, the air supply unit also includes a cold air circulation component. The cold air circulation component includes a cold air circulation duct 10, a cold air circulation electric butterfly valve 11, and a cold air outlet electric butterfly valve 12. The two ends of the cold air circulation duct 10 are connected to the air outlet box 5 and the cold air inlet pipe 1, respectively. The cold air circulation duct 10 is also equipped with a cold air circulation electric butterfly valve 11, and the air outlet of the air outlet box 5 is equipped with a cold air outlet electric butterfly valve 12.

[0035] When the cooling air is directly discharged, the cold air circulation electric butterfly valve 11 is in the closed state, and the cold air outlet electric butterfly valve 12 is in the open state, so the cooling air is directly discharged from the air outlet box 5.

[0036] When the cooling air is circulating, the electric butterfly valve 11 for cooling air circulation is in the open state, and the electric butterfly valve 12 for cooling air outlet is in the closed state. The cooling air flows into the cooling air inlet pipe 1 through the cooling air circulation pipe 10 to form a cooling air circulation.

[0037] Furthermore, such as Figure 1 , 2 As shown in Figure 4, in order to facilitate the maintenance of the pipeline, both the cold air inlet pipe 1 and the cold air delivery pipe 3 are equipped with inspection doors 9 for easy inspection and maintenance.

[0038] Furthermore, such as Figure 3 As shown, to extend the flow path of the high-temperature flue gas in the cooling chamber, the cooling chamber 100 is provided with an inlet chamber and an outlet chamber. This allows the high-temperature flue gas to flow from the inlet chamber into the outlet chamber before being discharged. Furthermore, to ensure more uniform airflow within the inlet and outlet chambers and better cooling of the high-temperature flue gas, the inlet chamber 4 and outlet chamber 5 are each separated into two independent chambers by corresponding partitions. The two independent chambers of the inlet chamber 4 are respectively connected to one side of the inlet chamber and the outlet chamber of the cooling chamber 100, and the two independent chambers of the outlet chamber 5 are respectively connected to the cooling chamber... The air inlet chamber and the air outlet chamber of the cooling chamber 100 are connected on the other side. At the same time, in order to achieve separate cooling of different chambers in the cooling chamber, each independent chamber of the air inlet box 4 is equipped with a set of air supply units for cooling the air inlet chamber and the air outlet chamber in the cooling chamber 100. That is, the high temperature flue gas in the air inlet chamber of the cooling chamber 100 is cooled by a separate set of air supply units, and the high temperature flue gas entering the air outlet chamber from the air inlet chamber is cooled by a separate set of air supply units, which greatly improves the cooling effect.

[0039] Furthermore, to facilitate maintenance of the air inlet box and the air outlet box, the interior of the air inlet box 4 and the air outlet box 5 are separated into two independent chambers by corresponding partitions, and each independent chamber is equipped with an inspection door.

[0040] Furthermore, in order to achieve a more uniform flow of cooling air entering the cooling chamber and ensure a better cooling effect, the air inlet box 4 is equipped with a flow equalization mesh plate, which is located at the junction of the air inlet box 4 and the cooling chamber 100.

[0041] The specific working process of this utility model:

[0042] Cooling air is drawn into the cold air delivery pipe 3 through the cold air inlet pipe 1 by the fan 2 of a set of air supply units, and then sent into the air intake chamber of the cooling chamber 100 through an independent chamber in the air inlet box 4. The cooling air flows through the inside of the filter element, realizing the primary cooling of the high-temperature gas in the air intake chamber of the cooling chamber.

[0043] Meanwhile, under the action of the fan 2 of another air supply unit, the cooling air is drawn into the cold air delivery pipe 3 through the cold air inlet pipe 1, and then sent into the air outlet chamber of the cooling chamber 100 through another independent chamber in the air inlet box 4, so as to carry out secondary cooling of the high-temperature smoke and dust gas entering the air outlet chamber from the air inlet chamber.

[0044] When the cooling air is directly discharged, the electric butterfly valve 11 for cold air circulation is closed, and the electric butterfly valve 12 for cold air outlet is open, allowing the cooling air to be discharged directly through the air outlet box 5.

[0045] When the cooling air circulates, the cold air circulation electric butterfly valve 11 is in the open state, and the cold air outlet electric butterfly valve 12 is in the closed state, so that the cooling air re-enters the cold air inlet pipe 1, forming a circulating flow of cooling air.

[0046] This invention installs the air supply unit on the ground and uses it in conjunction with a high-temperature gas cooling and dust removal device, creating a ground-mounted structure that is easy to configure and assemble. This replaces the existing technology where the fan is directly installed on one side of the cooling chamber. The advantages of this design are: First, it not only saves installation space but also facilitates maintenance. Second, it reduces vibration of the entire system and avoids the problem of excessive noise caused by fan vibration. Third, the filter bag can be replaced at any time by entering the air inlet box, avoiding situations where maintenance is inconvenient due to weather conditions. Fourth, the cooling airflow is more uniform as it enters the cooling chamber through the air inlet box, resulting in a better cooling effect on the high-temperature flue gas in the cooling chamber.

[0047] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
