Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for ethylene glycol production. Background Technology

[0002] The production of ethylene glycol generates waste gas, which usually needs to be properly treated and purified. Spray towers are a common type of waste gas treatment equipment.

[0003] Acidic components in the exhaust gas react with the absorbent to form insoluble substances, which crystallize and deposit on the surface of the packing material, resulting in a decrease in porosity and thus affecting the exhaust gas treatment efficiency. Traditional spray towers require periodic shutdowns to disassemble the packing material for manual washing or replacement, leading to long-term production interruptions and time-consuming and labor-intensive manual maintenance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste gas treatment device for ethylene glycol production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas treatment device for ethylene glycol production includes a tower body. Multiple layers of packing frames are fixedly installed in the middle of the tower body. A rotating disk is rotatably installed at the bottom of each packing frame through bearing components. Each packing frame is connected to the other layers of packing frames through a connecting shaft to achieve synchronous movement. The rotating disk is driven to rotate by a motor component.

[0007] An annular spray frame is installed above the packing frame. Spray nozzles are installed at the bottom of the spray frame. A brush roller is installed in the middle of the spray frame via a mounting bracket. The brush roller passes through a mounting groove opened in the upper part of the packing frame.

[0008] In addition, a preferred structure is that an air inlet pipe is provided on one side of the bottom of the tower body, and a reaction liquid spraying mechanism is provided on the upper part of the tower body.

[0009] In addition, a preferred structure is that a motor is installed inside the bottom of the tower body, the output end of the motor is driven and connected to a magnetic coupler, the output end of the magnetic coupler is connected to a drive shaft, and the drive shaft is rotatably mounted on the bottom wall of the tower body.

[0010] Furthermore, in a preferred configuration, the space between the packing frame and the rotating disk is filled with packing material.

[0011] Furthermore, in a preferred configuration, the bottom of the rotating disk is connected to the drive shaft to achieve power transmission, and a connecting shaft is installed on the upper part of the rotating disk, the connecting shaft passing through the middle of the stuffing box.

[0012] In addition, a preferred structure is that one end of the spray frame extends out of the tower body and is connected to a connecting pipe, which is connected to an external water source.

[0013] Furthermore, in a preferred configuration, the bottom of the mounting bracket is rotatably connected to a brush roller via a bearing.

[0014] In addition, a preferred structure is that a waste liquid outlet 1 is provided at the bottom of the tower body, a solenoid valve is configured in the waste liquid outlet 1, and a waste liquid outlet 2 is provided below the waste liquid outlet 1.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this invention, multiple electrically rotating discs are installed in the middle of the tower body. When the discs rotate, they drive the packing material to move passively. In conjunction with the spray frame, cleaning liquid and brush rollers are sprayed to brush the moving packing material, which can effectively clean the surface of the packing material and improve the cleaning efficiency of the packing material. The entire cleaning process does not require manual intervention, ensuring the waste gas treatment efficiency of the packing material. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A waste gas treatment device for ethylene glycol production includes a tower body 1. A multi-layer packing frame 4 is fixedly installed in the middle of the tower body 1. A rotating disk 42 is rotatably installed at the bottom of each packing frame 4 through a bearing component. Each packing frame 4 is connected to the other layers of the packing frame 4 through a connecting shaft 33 to achieve synchronous movement. The rotating disk 42 is driven to rotate by a motor component 3.

[0024] An annular spray frame 8 is installed above the packing frame 4. Spray nozzles 81 are installed at the bottom of the spray frame 8. A brush roller 91 is installed in the middle of the spray frame 8 via a mounting bracket 9. The brush roller 91 passes through the mounting groove 41 opened in the upper part of the packing frame 4.

[0025] An air inlet pipe is provided on one side of the bottom of the tower body 1, and a reaction liquid spraying mechanism 2 is provided on the upper part of the tower body 1. The reaction liquid spraying mechanism 2 sprays the reaction liquid downward from the upper part of the tower body 1 and contacts the exhaust gas.

[0026] A motor component 3 is installed inside the bottom of the tower body 1. The output end of the motor component 3 is connected to a magnetic coupler 31. The output end of the magnetic coupler 31 is connected to a drive shaft 32. The drive shaft 32 is rotatably mounted on the bottom wall of the tower body 1. The drive shaft 32 is installed inside the tower body 1 and achieves contactless transmission through the magnetic coupler 31.

[0027] The space between the packing frame 4 and the rotating disk 42 is filled with packing material.

[0028] The bottom of the rotating disk 42 is connected to the drive shaft 32 to achieve power transmission. A connecting shaft 33 is installed on the upper part of the rotating disk 42. The connecting shaft 33 passes through the middle of the packing frame 4. The packing frame 4 and the connecting shaft 33 do not have a mechanical connection.

[0029] One end of the spray frame 8 extends out of the tower body 1 and is connected to a connecting pipe 5. The connecting pipe 5 is connected to an external water source, which introduces the packing cleaning liquid into the spray frame 8 and sprays it out from the spray nozzle 81.

[0030] The bottom of the mounting bracket 9 is rotatably connected to a brush roller 91 via a bearing, and the brush roller 91 is provided with bristles.

[0031] Waste liquid outlet 6 is provided at the bottom of tower body 1. A solenoid valve is installed in waste liquid outlet 6. Waste liquid outlet 7 is provided below waste liquid outlet 6.

[0032] In this embodiment, exhaust gas is introduced through an air inlet pipe at the bottom of the tower body 1, and the reaction liquid is sprayed out from the top of the tower body 1 through the reaction liquid spraying mechanism 2. The reaction liquid is sprayed onto the packing in the packing frame 4, and the packing with the attached reaction liquid reacts with the exhaust gas.

[0033] The entire reaction process and the more specific reaction principles are common knowledge to those skilled in the art and will not be explained further.

[0034] When the packing is being maintained and cleaned, the tower body 1 is in a stopped state. At this time, the motor 3 drives the drive shaft 32 to rotate through the magnetic coupler 31. The drive shaft 32 drives the rotating disk 42 to rotate, and the packing placed in the rotating disk 42 and the packing frame 4 moves due to the rotation of the rotating disk 42.

[0035] The packing frame 4 remains stationary, and the brush roller 91 set in the middle of the packing frame 4 will come into contact with the moving packing and brush the surface of the packing through the brush bristles.

[0036] At the same time, the external water source will pump the cleaning solution for cleaning the packing material into the spray frame 5 through the connecting pipe 5. The spray frame 5 will spray the cleaning solution out through multiple spray nozzles 81 and wet the packing material.

[0037] The rotating disks 42 on each layer are connected by a connecting shaft 33, enabling them to move synchronously.

[0038] Then, the cleaned wastewater will fall into the waste liquid outlet 6 at the bottom of the tower body 1. The waste liquid outlet 6 is equipped with a solenoid valve, which is turned on and off by an external control mechanism according to the working status (valve plate switch).

[0039] When the solenoid valve opens, wastewater is discharged from waste liquid outlet 6 into waste liquid outlet 7.

[0040] Holes are provided on both the packing frame 4 and the rotating disk 42 to ensure the flow of exhaust gas.

[0041] Among them, the reaction liquid spraying mechanism 2 is the basic configuration of the spraying tower, and its specific structure will not be explained further.

[0042] Throughout the cleaning process, no manual disassembly of the structural components of the tower body 1 is required. The rotating disk 42 driven by the motor component 3 moves the packing material, and the cleaning liquid is sprayed onto the packing material by the spray frame 8. The rotating cleaning achieves a highly efficient cleaning effect.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
