Description

Technical Field

[0001] This utility model relates to the field of pipeline structure, and in particular to an energy-saving humidification tower bypass pipeline. Background Technology

[0002] A humidification tower is a device that produces highly dispersed water mist. It is mainly used to improve the efficiency of electrostatic precipitators, reduce the resistivity of the exhaust gas from the kiln, and increase the moisture content of the flue gas entering the electrostatic precipitator. When in use, the humidification tower needs to be transported into the kiln tail high-temperature flue gas with the assistance of bypass pipes and exhaust fans.

[0003] The existing bypass pipe is a single-pipe structure, with one end connected to a high-temperature fan and the other end bolted to the top of the tower via a flange. Although it has high strength and good weather resistance, it also has other problems during use, such as a long hot air delivery process and increased resistance due to air leakage in the humidification tower system pipes, which generally reaches 800Pa. This leads to increased power consumption of the exhaust fan, increasing the operating cost of the equipment and reducing its practicality. To solve the above problems, we propose an energy-saving humidification tower bypass pipe. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving humidification tower bypass pipe, which solves the problem that existing bypass pipes do not have the function of guiding air switching.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an energy-saving humidification tower bypass pipe includes a tower body, a shell is bolted to the surface of the tower body, a first conveying air pipe and a second conveying air pipe are respectively installed through the top of the shell, the other end of the first conveying air pipe is bolted to the top of the tower body through a flange, the other end of the second conveying air pipe is connected to the surface of the tower body, a fixed pipe is installed through the bottom of the shell, a threaded rod is rotatably connected to the inside of the shell through a bearing, the other end of the threaded rod passes through and extends to the outside of the shell, a movable block is threadedly connected to the surface of the threaded rod, a baffle plate is welded to the top of the movable block through a fixing component, and air guide plates are symmetrically installed at the bottom of the baffle plate.

[0006] The above technical solution enables quick airflow switching, is simple and convenient to operate, reduces the hot air flow path during the operation of the raw material mill system, reduces temperature loss, lowers the operating cost of the equipment, and is highly practical.

[0007] The present invention is further configured such that: two limiting rods are provided through one side of the movable block, and both ends of the limiting rods are welded to the inside of the shell.

[0008] By adopting the above technical solution, the moving block can be limited by the setting of the limiting rod, so as to prevent the moving block and the wind deflector from flipping over during the left and right movement.

[0009] The present invention is further configured such that a throttle is welded to the other end of the threaded rod.

[0010] By adopting the above technical solution and by setting the throttle, it is easy for personnel to rotate the threaded rod.

[0011] The present invention is further configured such that: two fixing sleeves are fixedly sleeved on the surface of the first conveying air duct, two support plates are bolted to the bottom of the fixing sleeves, and the other side of the support plates is bolted to the surface of the tower body by screws.

[0012] By adopting the above technical solution, the first conveying air duct can be fixed and supported by the fixed sleeve and support plate, thereby reducing the pressure of the first conveying air duct on the shell.

[0013] The present invention is further configured such that the diameter of the baffle plate is larger than the diameter of the first conveying air pipe.

[0014] The above technical solution can improve the sealing effect of the wind baffle on the pipeline.

[0015] The present invention is further configured such that the housing, threaded rod, and moving block are all made of stainless steel.

[0016] By adopting the above technical solution, the housing, threaded rod, and moving block have the characteristics of high strength, low density, and excellent corrosion resistance.

[0017] The present invention is further configured such that a maintenance plate is bolted to the front of the housing.

[0018] By adopting the above technical solution and setting up the inspection plate, it is convenient for personnel to inspect and maintain the inside of the shell.

[0019] In summary, this utility model has the following beneficial effects:

[0020] This invention first installs an exhaust fan at the other end of a fixed pipe, allowing high-temperature exhaust gas to enter the casing from the fixed pipe. When the raw material grinding system is running, holding the handle and turning it clockwise causes the baffle plate to move to the right through the cooperation of the threaded rod and the moving block. As the baffle plate moves to the right, it blocks the bottom end of the first conveying air pipe, allowing the high-temperature exhaust gas to directly enter the tower body from the second conveying air pipe with the shortest travel distance. When the raw material grinding system stops, holding the handle and turning it counterclockwise causes the baffle plate to move to the left, blocking the bottom end of the second conveying air pipe. This allows the exhaust gas to flow upward from the first conveying air pipe and enter the tower body. It features a quick airflow switching function, is simple and convenient to operate, reduces the hot air flow distance during the operation of the raw material grinding system, reduces temperature loss, lowers the operating cost of the equipment, and is highly practical.

At the other end, the high-temperature exhaust gas enters the shell 2 from the fixed pipe 5. When the raw material mill system is running, hold the handle 10 and turn it clockwise. When the handle 10 is turned clockwise, it will cause the baffle plate 8 to move to the right through the cooperation of the threaded rod 6 and the moving block 7. When the baffle plate 8 moves to the right, it will block the bottom end of the first conveying air pipe 3. At this time, the high-temperature exhaust gas will directly enter the tower body 1 from the second conveying air pipe 4 with the shortest stroke. When the raw material mill system stops, hold the handle 10 and turn it counterclockwise. When the handle 10 is turned counterclockwise, it will cause the baffle plate 8 to move to the left. When the baffle plate 8 moves to the left, it will block the bottom end of the second conveying air pipe 4, allowing the exhaust gas to flow upward from the first conveying air pipe 3 and enter the tower body 1.

[0033] Brief description of the operation: First, install the exhaust fan at the other end of the fixed pipe 5 so that the high-temperature exhaust gas enters the shell 2 from the fixed pipe 5. When the raw material grinding system is running, hold the handle 10 and turn it clockwise. When the handle 10 is turned clockwise, the baffle 8 will move to the right through the cooperation of the threaded rod 6 and the moving block 7. When the baffle 8 moves to the right, it will block the bottom end of the first conveying air pipe 3.
