Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a novel gas compensation device. Background Technique

[0002] In many industrial and production fields, there are many devices and processes that require the natural discharge of medium- and high-temperature flue gas. For example, in iron and steel smelting, a large amount of medium- and high-temperature flue gas is generated during the blast furnace ironmaking process, which contains components such as carbon monoxide and sulfur dioxide. After preliminary treatment, these flue gases are naturally discharged through specific channels to maintain normal production. Also, during cement production, high-temperature calcination in the rotary kiln generates medium- and high-temperature flue gas, which contains dust and harmful gases. To ensure cement quality and production efficiency, these flue gases also need to be naturally discharged. In addition, in some small metal foundries, the medium- and high-temperature flue gas generated by the melting furnace is also treated by natural discharge.

[0003] During the natural discharge of medium- and high-temperature flue gas, in order to increase the flow rate of the flue gas, it is often necessary not only to extend the height of the flow-through pipeline, but also to install a wind-drawing device with a relatively large power at the end of the pipeline, which greatly increases the construction cost and reduces the economic benefits. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the background technique, and a novel gas compensation device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A novel gas compensation device includes a main pipeline, a mixing gas chamber is communicated with the top surface of the main pipeline, a first temperature measuring port and a second temperature measuring port are respectively installed on the outer side of the main pipeline, a flow detection port is installed on the outer side of the main pipeline, an arc-shaped seat is fixedly installed on the bottom surface of the main pipeline, a flue gas inlet is communicated with the bottom surface of the main pipeline, and the flue gas inlet is located at the center of the arc-shaped seat. A distribution chamber is opened in the arc-shaped seat, and a plurality of air inlet pipes are symmetrically communicated with the bottom surface of the arc-shaped seat, and each air inlet pipe is communicated with the distribution chamber. A plurality of air outlet pipes are fixedly installed in the main pipeline, and each air outlet pipe is communicated with the distribution chamber.

[0007] Preferably, a plurality of communication grooves are opened on the bottom wall of the main pipeline, and each communication groove is communicated with the distribution chamber, and each air outlet pipe is installed on the corresponding communication groove. The top outlet of each air outlet pipe is spirally arranged along the inner wall of the main pipeline.

[0008] Preferably, the inner diameter between the bottom end and the top end of each air outlet pipe gradually decreases.

[0009] Preferably, the first temperature measuring port and the second temperature measuring port are located on the same side of the main pipeline.

[0010] Preferably, a first connecting flange is installed at the bottom end of the main pipeline, and the bottom end of the mixed gas chamber is connected to the main pipeline through the first connecting flange.

[0011] Preferably, a second connecting flange is installed at the top end of the mixed gas chamber, and a flow control valve is installed on each intake pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By setting devices such as an arc-shaped seat, intake pipes, and outlet pipes, when there is a temperature difference inside and outside the main pipeline, under the action of atmospheric pressure, a large amount of normal-temperature air enters the distribution chamber through the intake pipes, and then through the guidance of the outlet pipes, the normal-temperature air forms an upward spiral air flow inside the main pipeline, further promoting the flow of the flue gas inside the pipeline. At the same time, it helps the flue gas to form a stable flow state inside the pipeline, enhancing the stability of the flue gas circulation.

[0014] 2. By setting devices such as an outlet pipe, a first temperature measuring port, and a second temperature measuring port, the inner diameter of the outlet pipe gradually decreases, thereby increasing the gas flow rate at the outlet end of the outlet pipe. And through the flow control valve installed on the intake pipe, the gas flow rate can be effectively controlled. Also, through the first temperature measuring port and the second temperature measuring port, it is convenient for engineers to timely discover the abnormal temperature rise caused by local ash accumulation in the pipeline, thus avoiding potential safety hazards and equipment damage.

[0015] In summary, when in use, by setting devices such as an arc-shaped seat, intake pipes, and outlet pipes, the present utility model can utilize atmospheric pressure to make a large amount of normal-temperature air form an upward spiral air flow, drive the flue gas to form a stable flow state inside the pipeline, and further promote the circulation of the flue gas inside the pipeline. Moreover, there is no need to extend the height of the pipeline or add wind power equipment, greatly reducing the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-3 , a new type of gas compensation device, including a main body pipeline 1. The top surface of the main body pipeline 1 is communicated with a mixing gas chamber 6. A second connection flange 8 is installed at the top end of the mixing gas chamber 6. Through the second connection flange 8, the mixing gas chamber 6 can be connected to the flue gas treatment equipment. At the same time, through the mixing gas chamber 6, it is convenient to mix air and flue gas to form a stable air flow, which helps to reduce the fluctuation and turbulence of the air flow and improve the stability of emissions. A first connection flange 7 is installed at the bottom end of the main body pipeline 1, and the bottom end of the mixing gas chamber 6 is connected to the main body pipeline 1 through the first connection flange 7. A first temperature measurement port 2 and a second temperature measurement port 3 are respectively installed on the outer side of the main body pipeline 1. The first temperature measurement port 2 and the second temperature measurement port 3 are located on the same side of the main body pipeline 1. Through the first temperature measurement port 2 and the second temperature measurement port 3, it is helpful to capture the subtle differences in the temperature distribution of the flue gas in the main body pipeline 1, and to more comprehensively understand the temperature condition inside the pipeline, which is convenient for engineers to timely discover the abnormal increase in temperature caused by local ash accumulation in the pipeline, thereby avoiding potential safety hazards and equipment damage. A flow detection port 9 is installed on the outer side of the main body pipeline 1 to facilitate detecting the transmission speed of the flue gas. An arc-shaped seat 4 is fixedly installed on the bottom surface of the main body pipeline 1. A flue gas inlet 5 is communicated with the bottom surface of the main body pipeline 1, and the flue gas inlet 5 is located at the center of the arc-shaped seat 4. A distribution chamber 13 is provided in the arc-shaped seat 4;

[0022] The bottom surface of the arc-shaped seat 4 is symmetrically connected with a plurality of air inlet pipes 11. A flow control valve 12 is installed on each air inlet pipe 11. Through the flow control valve 12, it is convenient to effectively control the flow velocity of the gas. By controlling the speed of the external air entering, the velocity of the flue gas in the pipe is regulated. Each air inlet pipe 11 is connected to the distribution chamber 13. A plurality of air outlet pipes 10 are fixedly installed in the main pipe 1, and each air outlet pipe 10 is connected to the distribution chamber 13. A plurality of communication grooves 14 are formed on the bottom wall of the main pipe 1, and each communication groove 14 is connected to the distribution chamber 13. Each air outlet pipe 10 is installed on the corresponding communication groove 14. The top outlet of each air outlet pipe 10 is spirally arranged along the inner wall of the main pipe 1. The inner diameter between the bottom end and the top end of each air outlet pipe 10 gradually decreases, thereby increasing the air flow velocity at the outlet end of the air outlet pipe 10. It should be noted that the normal-temperature air transmitted at the outlet end of each air outlet pipe 10 will form a spiral on the inner wall of the main pipe 1, thereby entraining the flue gas and making the flue gas spiral upward and discharged. The spiral airflow can make the normal-temperature air and the flue gas contact more fully, improve the heat exchange efficiency, reduce the resistance in the pipe at the same time, reduce the pressure loss, help the flue gas to form a stable flow state in the pipe, and improve the stability and reliability in the main pipe 1.

[0023] When the present utility model is in use, medium-high temperature flue gas is injected into the main pipe 1 through the flue gas inlet 5. Then, under the heat conduction of the flue gas, a temperature difference appears inside and outside the pipe in the main pipe 1. Thus, a large amount of normal-temperature air enters the distribution chamber 13 through a plurality of air inlet pipes 11 installed on the bottom surface of the arc-shaped seat 4 under the action of atmospheric pressure. Then, all the normal-temperature gas fills the inside of the distribution chamber 13 and then evenly enters the main pipe 1 through a plurality of air outlet pipes 10 to form an upward spiral airflow, which further promotes the rapid flow of the flue gas in the main pipe 1. At the same time, the spiral airflow can make the normal-temperature air and the flue gas contact more fully, improve the heat exchange efficiency, reduce the resistance in the pipe at the same time, reduce the pressure loss, help the flue gas to form a stable flow state in the pipe, and monitor the temperature of the flue gas in the main pipe 1 through the first temperature measuring port 2 and the second temperature measuring port 3 installed on the same side of the outside of the main pipe 1, which is convenient for engineers to timely discover the abnormal increase in temperature caused by local ash accumulation in the pipe, thereby avoiding potential safety hazards and equipment damage.

[0024] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
