Description

Technical Field

[0001] This utility model relates to the field of flue gas distributor technology, and more specifically, to a flue gas distributor structure with adjustable flow rate. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses combustible materials as fuel to produce electricity. Its basic production process is as follows: when fuel is burned, it heats water to generate steam, which converts the chemical energy of the fuel into heat energy. The steam pressure drives the turbine to rotate, converting the heat energy into mechanical energy. Then, the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] Currently, many thermal power plants require zero wastewater discharge for environmental upgrades, so flue gas distributors are often used. These distributors mainly use centrifugal atomizers to atomize wastewater and spray it into a wastewater drying tower, where it exchanges heat and mass with the hot flue gas being fed into the tower to achieve the purpose of drying. However, most existing flue gas distributors often cannot adjust the internal flue gas flow rate. When there are multiple flue gas inputs, the amount of input flue gas may change. If the flow rate is too high, safe production inside the reaction tower cannot be guaranteed. If the flow rate is too low, the heat exchange efficiency inside the reaction tower will be reduced. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a flue gas distributor structure with adjustable flow rate, which has the advantage of adjusting the flue gas flow rate according to the usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flow rate flue gas distributor structure, comprising:

[0006] A fixing plate, wherein a connecting piece is fixedly installed on the front side of the fixing plate;

[0007] An adjustment mechanism is disposed inside the connecting piece;

[0008] The adjusting mechanism includes a circular plate, the outer surface of which is fixedly sleeved with the interior of a connecting piece. A connecting ring is fixedly sleeved on the outer surface of the circular plate, and an air intake pipe is fixedly sleeved inside the connecting ring. A vertical plate is fixedly installed behind the top end of the air intake pipe, and a motor is fixedly installed on the front of the vertical plate. A rotating shaft is fixedly sleeved on the other end of the motor's output shaft, and a gear is fixedly sleeved on the other end of the rotating shaft. A gear ring is meshed with the outer surface of the gear, and the outer surface of the gear ring is movably sleeved with the interior of the circular plate and the air intake pipe, respectively. A baffle is fixedly sleeved inside the gear ring, and the back of the baffle is movably connected to the front of the circular plate.

[0009] As a preferred embodiment of this utility model, a fixing ring is fixedly sleeved on the front end of the outer surface of the air intake pipe, and a circular groove is formed on the outer surface of the fixing ring.

[0010] As a preferred embodiment of this utility model, a connecting plate is movably connected to the back of the fixing plate, and a flue gas distributor body is fixedly installed on the back of the connecting plate. A round block is fixedly sleeved inside the connecting plate, and the outer surface of the round block is movably sleeved with the inside of the fixing plate.

[0011] As a preferred embodiment of this utility model, a rotating block is movably fitted inside the circular block, and a twisting block is fixedly installed on the back of the rotating block.

[0012] As a preferred embodiment of this utility model, a screw is fixedly installed on the front side of the rotating block, and a moving block is threaded onto the outer surface of the screw.

[0013] As a preferred embodiment of this utility model, a hinge block is fixedly installed on the outer surface of the moving block, and a moving rod is hinged inside the hinge block.

[0014] As a preferred embodiment of this utility model, the other end of the moving rod is hinged to a rotating rod, and the other end of the rotating rod is hinged to the interior of the outer surface of the circular block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a motor, a rotating shaft, a gear ring, and a baffle, allows the rotating shaft to drive the gear to rotate when the motor is running. Since the gear meshes with the gear ring, the gear will drive the baffle to rotate through the gear ring. At this time, the back of the baffle will block the air inlet of the circular plate during rotation, thereby adjusting the instantaneous flow rate of the flue gas. This achieves the effect of adjusting the flue gas flow rate according to the usage requirements, making it convenient for operators to use in daily life.

[0017] 2. This utility model, by setting a screw, a moving block, a moving rod, and a rotating rod, allows the screw to rotate under the influence of the rotating block when the screwing block drives the rotating block to rotate. Since the screw is threadedly connected to the moving block, the screw will drive the hinge block to move through the moving block. Then, the hinge block will drive the rotating rod to move through the moving rod. At this time, the rotating rod will rotate around the hinge point with the circular block as the axis. When the rotating rod rotates 90 degrees, it will release the locking effect on the entire fixed plate, thereby facilitating the assembly and disassembly of the entire fixed plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides an adjustable flow rate flue gas distributor structure, comprising:

[0026] Fixed plate 1, with connecting piece 2 fixedly installed on the front side of fixed plate 1;

[0027] The adjustment mechanism is located inside the connecting piece 2;

[0028] The adjustment mechanism includes a circular plate 3, the outer surface of which is fixedly sleeved with the interior of the connecting piece 2. A connecting ring 4 is fixedly sleeved on the outer surface of the circular plate 3. An air intake pipe 5 is fixedly sleeved inside the connecting ring 4. A vertical plate 6 is fixedly installed behind the top of the air intake pipe 5. A motor 7 is fixedly installed on the front of the vertical plate 6. A rotating shaft 8 is fixedly sleeved on the other end of the output shaft of the motor 7. A gear 9 is fixedly sleeved on the other end of the rotating shaft 8. A gear ring 10 is meshed with the outer surface of the gear 9. The outer surface of the gear ring 10 is movably sleeved with the interior of the circular plate 3 and the air intake pipe 5, respectively. A baffle 11 is fixedly sleeved inside the gear ring 10. The back of the baffle 11 is movably connected to the front of the circular plate 3.

[0029] When the operator starts the motor 7, the gear 9 meshes with the gear ring 10, and the rotating shaft 8 drives the gear ring 10 to rotate through the gear 9. Due to the design of the circular plate 3 and the air inlet pipe 5, the gear ring 10 drives the baffle 11 to rotate between the circular plate 3 and the air inlet pipe 5. At this time, the back of the baffle 11 will block the air inlet of the circular plate 3 during rotation, thereby adjusting the instantaneous flow rate of the flue gas.

[0030] Among them, a fixing ring 23 is fixedly sleeved on the front end of the outer surface of the air intake pipe 5, and a circular groove 12 is opened on the outer surface of the fixing ring 23.

[0031] Due to the design of the retaining ring 23 and the circular groove 12, the intake pipe 5 can be easily connected to other pipes.

[0032] The back of the fixed plate 1 is movably connected to the connecting plate 13, the back of the connecting plate 13 is fixedly installed with the flue gas distributor body 22, and the inside of the connecting plate 13 is fixedly sleeved with a round block 14, the outer surface of the round block 14 is movably sleeved with the inside of the fixed plate 1.

[0033] The design of the four round blocks 14 will provide good positioning for the connection between the fixing plate 1 and the connecting plate 13.

[0034] The circular block 14 has a rotating block 15 movably connected inside it, and a screwing block 16 is fixedly installed on the back of the rotating block 15.

[0035] Since the outer surface of the rotating block 15 is movably connected to the inside of the circular block 14, the rotating block 15 can rotate inside the circular block 14. When the operator turns the turning block 16, the rotating block 15 will rotate under the drive of the turning block 16.

[0036] Among them, a screw 17 is fixedly installed on the front of the rotating block 15, and a moving block 18 is threaded onto the outer surface of the screw 17.

[0037] When the rotating block 15 rotates, it will drive the screw 17 to rotate. Since the outer surface of the screw 17 is connected to the internal thread of the moving block 18, the rotation of the screw 17 will drive the moving block 18 to move.

[0038] Among them, a hinge block 19 is fixedly installed on the outer surface of the moving block 18, and a moving rod 20 is hinged inside the hinge block 19.

[0039] When the moving block 18 moves, it will drive the moving rod 20 to move through the hinge block 19.

[0040] The other end of the moving rod 20 is hinged to a rotating rod 21, and the other end of the rotating rod 21 is hinged to the interior of the outer surface of the circular block 14.

[0041] When the moving rod 20 rotates, it will drive the rotating rod 21 to rotate around the hinge point with the circular block 14. When the rotating rod 21 rotates 90 degrees, it will release the lock on the entire fixed plate 1, thereby allowing the fixed plate 1 and the connecting plate 13 to be separated.

[0042] Working principle and usage process of this utility model:

[0043] When the operator needs to adjust the flue gas flow rate, the operator starts the motor 7. At this time, the rotating shaft 8 will drive the gear 9 to rotate. Since the outer surface of the gear 9 is meshed with the outer surface of the gear ring 10, when the gear 9 rotates, it will drive the gear ring 10 to rotate between the circular plate 3 and the air inlet pipe 5. At the same time, the baffle 11 will rotate under the drive of the gear ring 10. Since the back of the baffle 11 is movably connected to the front of the circular plate 3, when the baffle 11 rotates, it will block the air inlet on the circular plate 3, thereby adjusting the instantaneous flow rate of the flue gas, and thus achieving the function of adjusting the flue gas flow rate according to the usage requirements.

[0044] When the operator needs to disassemble the entire fixed plate 1, the operator rotates the four turning blocks 16 back and forth. The turning blocks 16 will drive the rotating block 15 to rotate, and then the rotating block 15 will drive the screw 17 to rotate. Since the outer surface of the screw 17 is connected to the internal thread of the moving block 18, when the screw 17 rotates, it will drive the moving block 18 to move. Then the moving block 18 will drive the hinge block 19 to move. When the hinge block 19 moves, it will drive the moving rod 20 to move. Then the other end of the moving rod 20 will drive the rotating rod 21 to move. At this time, the rotating rod 21 will rotate around the hinge point with the circular block 14 as the axis. When the rotating rod 21 rotates 90 degrees, the rotating rod 21 will release the locking effect on the entire fixed plate 1, so that the entire fixed plate 1 can be separated from the entire connecting plate 13, thereby realizing the function of conveniently disassembling and assembling the entire fixed plate 1.
