Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly relates to an integrated waste gas treatment device. Background Art

[0002] The discharge of waste gas into the ecological environment is part of gaseous pollution. Waste gas mainly includes formaldehyde, acetic acid, ethanol, etc., and malodorous gases such as chemical waste gas and gaseous hydrocarbons discharged from various industries. Waste gas treatment refers to reducing or eliminating the waste gas emissions generated during industrial production through various technical means to protect the environment and human health. By purifying the harmful substances in the waste gas through a waste gas treatment device and further treating the waste gas before discharging, the pollution to the ecological environment can be effectively reduced.

[0003] Existing waste gas treatment devices are mostly of combined structure. Each component is connected by pipelines and placed on the ground. The structure is not compact enough and occupies a large area. When the filter component in the waste gas treatment system is blocked, it is necessary to stop the machine to replace the filter element. There is a lack of a monitoring mechanism for the treated waste gas. When the waste gas is not completely purified and is directly discharged, it will pollute the environment. Summary of the Invention

Detailed implementation mode

[0035] In the embodiment of the present application, an integrated waste gas treatment device is provided. By controlling the rotation angle of the filter disc, the filtering area of the filter disc is switched to realize continuous and uninterrupted filtering of the filtering mechanism. The large purification tower mechanism is divided into three groups of small purification towers. The content of harmful substances in the waste gas is detected by a gas detector. Multiple groups of waste gas treatment devices are arranged in layers on the frame to form an integrated structure, solving the technical problems mentioned in the background art.

[0036] The technical solution in the embodiment of the present application is to solve the problems in the above background art, and the general idea is as follows:

[0037] Embodiment 1:

[0038] Please refer to Figures 1-10, the present invention provides a technical solution: an integrated waste gas treatment device, including a liquid tank 1, on which a frame 2 is provided, on the frame 2 there are a filtering mechanism 3 and a purification tower mechanism 4, the filtering mechanism 3 and the purification tower mechanism 4 are connected by a conveying pipeline 5, outside the liquid tank 1 there is a pump body 6, the pump body 6 is connected to a spraying pipeline 7, the spraying pipeline 7 extends into the interior of the purification tower mechanism 4, the purification tower mechanism 4 and the liquid tank 1 are connected by a reflux pipeline 8, the filtering mechanism 3 includes a first filtering component 31, a second filtering component 32 and a third filtering component 33, the first filtering component 31, the second filtering component 32 and the third filtering component 33 all include a fixed cover 331 and a filtering disc 332, on the outer ring of the filtering disc 332 there is a gear ring 333, the filtering disc 332 is driven by a power component 36, on the filtering disc 332 there are a first filter element 334 and a second filter element 335 fixed in a card slot, the purification tower mechanism 4 includes a first purification tower 41, a second purification tower 42 and a third purification tower 43, between the first purification tower 41 and the second purification tower 42 there is a first air pipe 44 connected, between the second purification tower 42 and the third purification tower 43 there is a second air pipe 45 connected, at the upper end of the third purification tower 43 there is a third air pipe 46 connected, the third air pipe 46 is connected to a gas detector 47, the gas detector 47 is connected to an exhaust pipe 48 and a return air pipe 49, on the exhaust pipe 48 there is a first valve 481 installed, on the return air pipe 49 there are a second valve 491 and a third valve 492 installed, and the other end of the return air pipe 49 is connected to the first purification tower 41.

[0039] Among them, both the first filter element 334 and the second filter element 335 are semi-circular structures. When the first filter element 334 on a set of filtering discs 332 is performing a filtering operation, the second filter element 335 on this filtering disc 332 does not participate in the filtering operation. Conversely, when the second filter element 335 on a set of filtering discs 332 is performing a filtering operation, the first filter element 334 on this filtering disc 332 does not participate in the filtering operation;

[0040] When the power component 36 works, it drives the gear ring 333 on the outer ring of the filtering disc 332 through the meshing transmission between teeth. The gear ring 333 drives the filtering disc 332 to rotate synchronously. The filtering disc 332 is divided into two filtering areas. By controlling the rotation angle of the filtering disc 332, the filtering areas of the filtering disc 332 are switched. When one of the filtering areas on the filtering disc 332 is blocked by impurities, a switch is made to rotate the blocked filter element out of the fixed cover 331, and at the same time rotate the clean filter element into the fixed cover 331, and continuous filtering is carried out by switching the corresponding filtering areas, so as to achieve continuous and uninterrupted filtering of the filtering mechanism 3 and improve the waste gas treatment efficiency;

[0041] The rotated and blocked filter element is exposed to the outside, and the filter element can be directly cleaned or replaced. The first filter element 334 and the second filter element 335 are fixedly connected to the filter disc 332 through card slots. Applying a certain external force can separately remove the filter element from the filter disc 332, facilitating the replacement and maintenance of the filter element.

[0042] Among them, the first purification tower 41, the second purification tower 42, and the third purification tower 43 together constitute the purification tower mechanism 4. The large purification tower mechanism 4 is divided into three groups of small purification towers and connected by pipelines. While ensuring the purification efficiency, the floor area of the overall waste gas treatment device is reduced.

[0043] The three groups of small purification towers are independently arranged and connected by pipelines. When a failure occurs in one of the purification towers, only local replacement and maintenance are required. The disassembly and maintenance are convenient, reducing the daily maintenance difficulty of the purification tower.

[0044] Among them, the waste gas is purified three times through the first purification tower 41, the second purification tower 42, and the third purification tower 43. The purified gas is discharged into the third gas pipe 46 and enters the gas detector 47 through the third gas pipe 46. At this time, the content of harmful substances in the waste gas is detected by the gas detector 47.

[0045] If the waste gas can meet the emission standards, the first valve 481 is opened, the second valve 491 and the third valve 492 are closed, and the exhaust passage of the exhaust pipe 48 is opened. The purified waste gas is discharged up to standard through the exhaust pipe 48.

[0046] If the waste gas cannot meet the emission standards, the first valve 481 is closed, the second valve 491 and the third valve 492 are opened, the gas return passage of the gas return pipe 49 is opened, and the incompletely purified waste gas enters the gas return pipe 49 and flows back to the first purification tower 41 through the gas return pipe 49 for cyclic purification until the waste gas can meet the emission standards. The content of harmful substances in the waste gas is detected in real time by the gas detector 47 to eliminate the potential safety hazards caused by the emission of incompletely purified waste gas and improve the quality of waste gas treatment.

[0047] In some examples, the power assembly 36 includes a motor reducer 361. The output shaft of the motor reducer 361 is fixedly connected to the drive shaft 362 through a coupling. Three groups of gears 363 are arranged on the drive shaft 362. The three groups of gears 363 are respectively meshed with the gear rings 333 of the first filter assembly 31, the second filter assembly 32, and the third filter assembly 33. The drive shaft 362 is connected to the frame 2 through a bearing seat 364.

[0048] Among them, when the motor reducer 361 works, it drives the drive shaft 362 at one end to rotate. The drive shaft 362 drives three groups of gears 363 to rotate synchronously. The three groups of gears 363 respectively drive the filter discs 332 of the first filter assembly 31, the second filter assembly 32, and the third filter assembly 33 to rotate synchronously. By controlling the number of rotation turns of the motor reducer 361, the rotation position of the filter disc 332 is precisely adjusted, and the filtering area of the filter disc 332 is flexibly switched.

[0049] In some examples, a slide bar is provided on the outer ring of the filter disc 332, and a slide groove is opened on the inner ring of the fixed cover 331. The slide bar of the filter disc 332 is slidably inserted into the slide groove of the fixed cover 331.

[0050] Among them, the fixed cover 331 remains stationary, and the filter disc 332 can rotate relative to the fixed cover 331. As Figure 8 shown, a notch is opened on the end face of the fixed cover 331 close to the filter disc 332, and the waste gas passage is communicated through this notch. When the first filter element 334 is located on one side of the notch, the waste gas is filtered and purified by the first filter element 334. When the second filter element 335 is located on one side of the notch, the waste gas is filtered and purified by the second filter element 335.

[0051] In some examples, an exhaust gas inlet pipe 34 is provided at one end of the first filter assembly 31, and an exhaust gas discharge pipe 35 is provided at one end of the third filter assembly 33. The first filter assembly 31, the second filter assembly 32, and the third filter assembly 33 are connected by pipelines, and the exhaust gas inlet pipe 34 is connected to the negative pressure fan assembly.

[0052] Among them, one end of the negative pressure fan assembly is connected to the waste gas treatment device, and the other end of the negative pressure fan assembly is connected to the waste gas main pipeline. Driven by the negative pressure fan assembly, the waste gas is discharged to the exhaust gas inlet pipe 34 through the waste gas main pipeline and enters the interior of the waste gas treatment device through the exhaust gas inlet pipe 34;

[0053] The waste gas is first filtered and purified by the first filter assembly 31, then by the second filter assembly 32, and then by the third filter assembly 33. The waste gas after three times of filtration and purification enters the exhaust gas discharge pipe 35, enters the conveying pipeline 5 through the exhaust gas discharge pipe 35, and enters the purification tower mechanism 4 through the conveying pipeline 5.

[0054] In some examples, brackets 37 are provided below the first filter assembly 31, the second filter assembly 32, and the third filter assembly 33.

[0055] In some examples, the bracket 37 includes a trough 371, and multiple groups of balls 372 are arranged in the trough 371, and the balls 372 are rotatably connected to the trough 371.

[0056] Among them, a bracket 37 structure is correspondingly arranged below each of the first filtering component 31, the second filtering component 32, and the third filtering component 33. The bracket 37 supports and holds the first filtering component 31, the second filtering component 32, and the third filtering component 33. The filter disc 332 of the filtering component is embedded in the trough 371 and contacts with multiple groups of ball bearings 372. The contact friction between the filter disc 332 and the bracket 37 is reduced by the multiple groups of ball bearings 372. While playing a supporting role, the bracket 37 ensures that the filter disc 332 can be normally driven by the power component 36, improving the operation stability of the waste gas treatment device.

[0057] In some examples, a packing layer 431 is provided inside each of the first purification tower 41, the second purification tower 42, and the third purification tower 43. An entrainment separator layer 432 is arranged above the packing layer 431. The entrainment separator layer 432 separates and removes particulate matters and droplets in the gas. And the spray pipeline 7 is located between the packing layer 431 and the entrainment separator layer 432. A packing support is installed at the bottom of the packing layer 431.

[0058] Among them, the waste gas flows from bottom to top, and the absorbent liquid flows from top to bottom. The gas-liquid two-phase in the tower flows countercurrently. The packing layer 431 provides the contact surface of the gas-liquid two-phase in the tower. Commonly used packings include Raschig rings, Pall rings, arc saddles, and rectangular saddles, etc. Select a suitable packing layer 431 according to actual usage requirements. The spray liquid is sprayed from the top of the tower onto the packing layer 431 through the spray pipeline 7 and flows down along the surface of the packing. The waste gas is sent from the bottom. By utilizing the contact between the waste gas and the liquid, the pollutants in the waste gas are transferred into the liquid to achieve the purification of the waste gas.

[0059] In some examples, drain openings 434 are respectively provided at the bottoms of the first purification tower 41, the second purification tower 42, and the third purification tower 43. Exhaust openings 433 are respectively provided at the tops of the first purification tower 41, the second purification tower 42, and the third purification tower 43. The exhaust opening 433 of the third purification tower 43 is connected to the third gas pipe 46. The drain openings 434 of the first purification tower 41, the second purification tower 42, and the third purification tower 43 are all connected to the reflux pipeline 8. A liquid changing pipe 11 is arranged on the side surface of the liquid tank 1, and a valve is installed on the liquid changing pipe 11.

[0060] Among them, the waste gas purified by the first purification tower 41 enters the first air pipe 44, enters the second purification tower 42 through the first air pipe 44, the waste gas purified by the second purification tower 42 enters the second air pipe 45, enters the third purification tower 43 through the second air pipe 45, the waste gas purified by the third purification tower 43 enters the third air pipe 46, after being detected by the gas detector 47, it is discharged up to standard through the exhaust pipe 48 or flows back and circulates for purification through the return air pipe 49. The liquid flows from top to bottom, and after completing the absorption and purification, it is concentrated at the bottoms of the first purification tower 41, the second purification tower 42, and the third purification tower 43. The liquid is concentrated and enters the return pipeline 8, and returns to the liquid tank 1 through the return pipeline 8 for recycling, and the absorption liquid is replaced through the liquid replacement pipe 11.

[0061] By adopting the above technical solution:

[0062] The filter disc 332 is divided into two filter areas. By controlling the rotation angle of the filter disc 332, the filter areas of the filter disc 332 are switched. When one of the filter areas on the filter disc 332 is blocked by impurities, the switching is carried out, the blocked filter element is rotated out of the fixed cover 331, and at the same time, the clean filter element is rotated into the fixed cover 331. Continuous filtration is carried out by switching the corresponding filter areas, so as to realize the continuous and uninterrupted filtration of the filtration mechanism 3, improve the waste gas treatment efficiency, and there is no need to stop the machine to replace the filter element;

[0063] The large purification tower mechanism 4 is divided into three groups of small purification towers and connected by pipelines. While ensuring the purification efficiency, the floor area of the overall waste gas treatment device is reduced, and the maintenance difficulty is reduced;

[0064] The gas detector 47 is used to detect the content of harmful substances in the waste gas. If the waste gas cannot be discharged up to standard, the first valve 481 is closed, the second valve 491 and the third valve 492 are opened, the return air passage of the return air pipe 49 is opened, the incompletely purified waste gas enters the return air pipe 49, and returns to the first purification tower 41 through the return air pipe 49 for circulating purification until the waste gas can be discharged up to standard, improving the waste gas treatment quality.

[0065] Embodiment 2:

[0066] Based on Embodiment 1, this embodiment introduces the specific structure of the frame 2 in an integrated waste gas treatment device. The frame 2 includes a bottom frame 21 and a top frame 22, and the top frame 22 is located above the bottom frame 21. The frame 2 is divided into an upper layer and a lower layer.

[0067] In some examples, the filtration mechanism 3 is installed and fixed on the bottom frame 21, and the purification tower mechanism 4 is installed and fixed on the top frame 22.

[0068] Among them, the filtering mechanism 3 is fixedly arranged at the lower layer position, and the purification tower mechanism 4 is fixedly arranged at the upper layer position. The purification tower mechanism 4 is located above the filtering mechanism 3. Multiple groups of waste gas treatment devices are arranged in layers on the frame 2 to form an integrated structure, which can be moved as a whole, is structurally compact, reduces the floor area, and improves the space utilization rate.

[0069] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
