Description

Technical Field

[0001] This utility model relates to a dehydration device before the exhaust gas duct intake fan, belonging to the technical field of exhaust gas treatment equipment. Background Technology

[0002] In industrial exhaust gas treatment processes, exhaust gas is transported through pipelines to an intake fan for further treatment. Due to the high moisture content of the exhaust gas, as the temperature decreases during pipeline transport, water vapor condenses due to supersaturation, causing condensate to enter the intake fan with the airflow. In practical applications, the entry of moisture into the fan causes numerous problems: moisture accelerates corrosion of core components such as impellers and bearings, significantly reducing equipment lifespan; water vapor mixes with particulate matter to form sticky deposits, disrupting the impeller's dynamic balance, leading to increased equipment vibration and abnormal noise, severely affecting system operational stability; the increased density of the humid exhaust gas causes increased fan load and reduced transport efficiency, and in extreme cases, may even trigger overload shutdown, interrupting the continuous operation of the exhaust gas treatment system. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a dehydration device before the exhaust gas pipeline inlet fan, which is simple in structure, easy to operate, effectively collects moisture in the exhaust gas conveying pipeline, prevents moisture from entering the inlet fan, extends the service life of the equipment, and ensures the stable operation of the exhaust gas treatment system.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a dehydration device before the exhaust gas inlet fan in a tail gas pipeline, including an exhaust gas conveying pipeline and a three-way pipe. The exhaust gas conveying pipeline includes a first conveying pipeline and a second conveying pipeline. The outlet of the first conveying pipeline is connected to the first port of the three-way pipe. The second port of the three-way pipe is connected to the air inlet of the inlet fan through the second conveying pipeline. The third port of the three-way pipe is connected to a wastewater collection tank through a connecting pipe. The exhaust gas is conveyed in the first conveying pipeline. The water condensed in the first conveying pipeline reaches the three-way pipe with the exhaust gas and flows into the wastewater collection tank through the third port of the three-way pipe and the connecting pipe under the action of gravity.

[0005] The first and third ports of the tee are arranged vertically opposite each other, and the second port of the tee is arranged horizontally.

[0006] The third port of the tee pipe is connected to the connecting pipe via a reducing flange; the reducing flange has a reducing hole in the center, the diameter of the large end hole of the reducing flange matches the diameter of the third port; the diameter of the small end hole of the reducing flange matches the inner diameter of the connecting pipe.

[0007] A ball valve is installed on the connecting pipe.

[0008] The exhaust gas conveying pipe, connecting pipe, and wastewater collection tank are all made of stainless steel.

[0009] Compared with the prior art, the advantages of this utility model are: a dehydration device before the exhaust gas pipeline inlet fan has a simple structure and is easy to operate. It can effectively collect the moisture in the exhaust gas conveying pipeline, prevent moisture from entering the inlet fan, reduce the corrosion rate of the internal parts of the inlet fan, improve the service life of the equipment, and ensure the stable operation of the exhaust gas treatment system. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of a dehydration device before the exhaust gas duct intake fan according to an embodiment of the present invention; In the diagram, 1 is the first conveying pipe, 2 is the tee pipe, 21 is the first port, 22 is the second port, 23 is the third port, 3 is the reducing flange, 4 is the connecting pipe, 5 is the ball valve, 6 is the wastewater collection tank, 7 is the air intake fan, and 8 is the second conveying pipe. Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 As shown in this embodiment, a dehydration device before the exhaust gas inlet fan includes an exhaust gas conveying pipe and a three-way pipe 2. The exhaust gas conveying pipe includes a first conveying pipe 1 and a second conveying pipe 8. The three-way pipe 2 has a first port 21, a second port 22, and a third port 23. The first port 21 and the third port 23 are arranged vertically opposite to each other, while the second port 22 is arranged horizontally. The first port 21 is connected to the first conveying pipe 1, and the third port 23 is connected to the air inlet of the inlet fan 7 through the second conveying pipe 8. The third port 23 is connected to a connecting pipe 4 through a reducing flange 3, and the outlet of the connecting pipe 4 is connected to a wastewater collection tank 6. The exhaust gas is conveyed in the first conveying pipe 1. When the water condensed in the first conveying pipe reaches the position of the three-way pipe 2 with the exhaust gas, it flows into the wastewater collection tank through the third port of the three-way pipe and the connecting pipe under the action of gravity. The wastewater collection tank is used to collect the moist wastewater conveyed from the connecting pipe, thus preventing the condensate from entering the inlet fan.

[0013] The inner diameter of the connecting pipe is smaller than the inner diameter of the exhaust gas delivery pipe to ensure that the exhaust gas is mainly delivered to the intake fan along the second delivery pipe.

[0014] A ball valve 5 is installed on the connecting pipe 4, which makes it easy to cut off the connecting pipe when the wastewater collection tank is under maintenance, thus ensuring the normal operation of the exhaust gas conveying system.

[0015] The reducing flange has a reducing hole at its center. The diameter of the reducing flange's large end hole matches the diameter of the third port. The diameter of the reducing flange's small end hole matches the inner diameter of the connecting pipe, thus achieving a transition connection between different pipe diameters.

[0016] The exhaust gas delivery pipes, connecting pipes, and wastewater collection tanks are all made of stainless steel. The intake fan is a centrifugal fan. The ball valves are either manual or electric, allowing control of the connecting pipe's on / off state as needed.

[0017] This application features a simple structure and convenient operation. It can effectively collect moisture in the exhaust gas conveying pipeline, prevent moisture from entering the intake fan, reduce the corrosion rate of internal components of the intake fan, improve the service life of the equipment, and ensure the stable operation of the exhaust gas treatment system.

[0018] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
