Description

Technical Field

[0001] This utility model relates to the field of desulfurization tower technology, specifically a desulfurization tower for treating waste gas from ceramic production. Background Technology

[0002] During ceramic production, kiln combustion and raw material calcination produce sulfur-containing oxides (SO₄²⁻). x The exhaust gas contains pollutants such as dust, so it needs to be desulfurized.

[0003] A search revealed a utility model patent with patent authorization announcement number CN118203940B, which discloses a ceramic waste gas desulfurization and dust removal device. This device includes a desulfurization tower, a wet electrostatic precipitator, and a PLC controller. The desulfurization tower and the wet electrostatic precipitator are connected via a flue gas conveying channel, and the lower end of the desulfurization tower is fixedly connected to an inlet flue. This invention employs a one-stop purification system, occupies a small area, and can effectively treat multiple pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides in flue gas in a single pass.

[0004] Traditional desulfurization towers mostly adopt spray tower or packed tower structures, but they have the following problems: particulate matter in the desulfurization liquid is easy to circulate with the desulfurization liquid, which can cause the spray system to be blocked and affect the desulfurization efficiency. At the same time, the packing is also easy to be blocked by particulate matter, which affects the desulfurization effect. Utility Model Content

[0005] The purpose of this invention is to provide a desulfurization tower for treating waste gas from ceramic production, which solves the problems of easy clogging of the spray system and packing material in traditional desulfurization towers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization tower for treating waste gas from ceramic production, comprising a tower body, packing material provided on the upper inner side of the tower body, an inlet pipe connected to the tower body, a submersible pump fixedly installed on the bottom inner side of the tower body, a conveying pipe fixedly connected to the output end of the submersible pump, the conveying pipe penetrating the tower body, a transition pipe connected to the body of the conveying pipe, an anti-clogging mechanism provided on the inner side of the transition pipe, a rotating ring rotatably connected inside the transition pipe, a filter screen fixedly connected to the inner wall of the rotating ring, a spray pipe installed at the end of the conveying pipe via a sealed bearing, a nozzle provided at the bottom of the spray pipe, a connecting block fixedly connected to the left side of the spray pipe, a motor fixedly installed on the left side of the tower body, the output shaft of the motor penetrating the tower body and connected to the tower body via a bearing, a square block fixedly connected to the end of the output shaft, the square block engaging with the connecting block.

[0007] Preferably, the number of nozzles is multiple, and the multiple nozzles are evenly distributed along the circumference of the spray pipe. The arrangement of multiple nozzles facilitates the uniform spraying of desulfurization liquid.

[0008] Preferably, the rotating ring is circular and made of rubber. A rubber rotating ring inherently possesses a certain degree of sealing performance.

[0009] Preferably, a fixing pin is fixedly connected to the rotating ring, and the fixing pin is rotatably connected to the transition tube. The fixing pin facilitates the rotation of the rotating ring.

[0010] Preferably, the anti-clogging mechanism includes a fixed rod fixedly connected to the inner wall of the transition pipe, a connecting sleeve fixedly connected to the end of the fixed rod, a rotating rod installed inside the connecting sleeve via a bearing, an impeller fixedly connected to one end of the rotating rod, and a brush fixedly connected to the other end of the rotating rod, the brush abutting against the filter screen. The anti-clogging mechanism effectively prevents and clears blockages in the filter screen.

[0011] Preferably, there are two fixing rods, and the two fixing rods are arranged symmetrically. The fixing rods provide support for the connecting sleeve.

[0012] Preferably, two baffles are fixedly connected to the rod body of the rotating rod, with the two baffles located above and below the connecting sleeve, respectively. The baffles provide waterproof protection for the bearings inside the connecting sleeve used to fix the rotating rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses an electric motor to drive the nozzle to rotate through the snap-fit ​​between the square block and the connecting block, thereby changing the direction of the nozzle and making the nozzle on the nozzle face upward, thus backwashing the packing and avoiding the packing blockage that would affect the effect of exhaust gas treatment.

[0015] 2. This utility model utilizes the linkage design of the impeller and brush in the anti-clogging mechanism. When the liquid flows through the transition pipe, the impeller is impacted by the water flow, causing the rotating rod to rotate and driving the brush to automatically clean the filter screen, effectively preventing clogging. This structure requires no additional power, reducing energy consumption while ensuring continuous smooth flow of desulfurization liquid, thus improving desulfurization efficiency and system stability.

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.

[0022] Please see Figures 1-3 A desulfurization tower for treating waste gas from ceramic production includes a tower body 1. Packing material 2 is installed on the upper inner side of the tower body 1. An inlet pipe 3 is connected to the tower body 1. A submersible pump 4 is fixedly installed at the bottom inner side of the tower body 1. A delivery pipe 5 is fixedly connected to the output end of the submersible pump 4, and the delivery pipe 5 penetrates the tower body 1. A transition pipe 7 is connected to the body of the delivery pipe 5. A rotating ring 9 is rotatably connected inside the transition pipe 7. The rotating ring 9 is circular and made of rubber. The rubber rotating ring 9 has a certain degree of sealing. A filter screen 10 is fixedly connected to the inner wall of the rotating ring 9. A fixing pin 11 is fixedly connected to the rotating ring 9 and rotatably connected to the transition pipe 7. The fixing pin 11 facilitates the rotation of the rotating ring 9. A spray pipe 6 is installed at the end of the delivery pipe 5 through a sealed bearing. A nozzle 12 is provided at the bottom of the spray pipe 6. Multiple nozzles 12 are evenly distributed along the circumference of the spray pipe 6. The arrangement of multiple nozzles 12 facilitates uniform spraying of desulfurization liquid. A connecting block 13 is fixedly connected to the left side of the spray pipe 6. A motor 14 is fixedly installed on the left side of the tower body 1. The output shaft of the motor 14 passes through the tower body 1 and is connected to the tower body 1 through a bearing. A square block 15 is fixedly connected to the end of the output shaft. The square block 15 is engaged with the connecting block 13.

[0023] Please see Figures 3-4An anti-clogging mechanism 8 is provided on the inner side of the transition pipe 7. This mechanism prevents the filter screen 10 from becoming clogged. The anti-clogging mechanism 8 includes a fixing rod 81 fixedly connected to the inner wall of the transition pipe 7. A connecting sleeve 82 is fixedly connected to the end of the fixing rod 81. A rotating rod 83 is mounted inside the connecting sleeve 82 via a bearing. An impeller 84 is fixedly connected to one end of the rotating rod 83, and a brush 86 is fixedly connected to the other end, with the brush 86 contacting the filter screen 10. There are two fixing rods 81, symmetrically arranged. The fixing rods 81 provide support for the connecting sleeve 82. Two baffles 85 are fixedly connected to the body of the rotating rod 83, located above and below the connecting sleeve 82 respectively. The baffles 85 provide waterproof protection for the bearing inside the connecting sleeve 82 used to fix the rotating rod 83.

[0024] The specific implementation process of this utility model is as follows: the waste gas from ceramic production enters the tower body 1 through the inlet pipe 3. Then, the submersible pump 4 inputs the desulfurization liquid at the bottom of the tower body 1 into the spray pipe 6 through the delivery pipe 5, and then sprays it out through the nozzle 12, thereby combining with the waste gas to desulfurize the waste gas. The desulfurization liquid after use will flow back into the tower body 1 for recycling. Subsequently, the desulfurized waste gas is discharged after being filtered by the packing 2. In addition, when the liquid flows through the transition pipe 7, the impeller 84 is driven by the water flow to rotate the rotating rod 83, which drives the brush 86 to automatically clean the filter screen 10, effectively preventing blockage. This structure does not require additional power, which reduces energy consumption and ensures that the desulfurization liquid is continuously unobstructed, improving the desulfurization efficiency and system stability. Later, the motor 14 drives the spray pipe 6 to rotate through the snap-fit ​​of the square block 15 and the connecting block 13, thereby changing the direction of the spray pipe 6 so that the nozzle 12 on the spray pipe 6 faces upward, thereby backwashing the packing 2 and avoiding blockage of the packing 2, which would affect the effect of waste gas treatment.
