Description

TECHNICAL FIELD

[0002] In the modern agricultural production process, a large amount of organic waste will be produced, such as straw, corn cob, rice bran, etc. A small part of these wastes will be used in other fields, such as livestock feed or other industries, but most of them will be destroyed and discarded, such as incineration, landfill, etc. This treatment method not only may cause environmental pollution, but also leads to the waste of renewable resources. Therefore, the technology of converting agricultural organic waste into organic fertilizer has emerged. Through crushing, fermentation and mixing other nutrients, waste is turned into treasure, and green and environmentally friendly organic fertilizer is produced, which is reused in agricultural production, greatly improving the resource recycling rate and reducing environmental pollution.

[0003] A large amount of waste gas will be produced during the production of organic fertilizer. These waste gases need to be treated before being discharged to avoid air pollution and damage to green and environmentally friendly production needs. Because the main component of organic fertilizer production waste gas is dust impurities, it usually does not include industrial pollution gas, so it generally does not need to be chemically treated and can be discharged after being removed by dust collection equipment. However, the dust produced during the production of organic fertilizer is rich in small particle impurities after fermentation. These small particle impurities have strong adhesion, and when treated with traditional cloth bag dust collectors or cyclone dust collectors, they are easily attached and hardened on the equipment, which requires frequent cleaning of the dust removal equipment, reducing the dust removal effect and affecting the production efficiency.

[0004] Therefore, the existing production begins to use gas incinerator as the first step equipment for waste gas treatment, which burns the small organic particles contained in the waste gas, thereby solving the adhesion problem. However, the existing gas incinerator is usually used for incinerating organic waste gas, and the combustion result is only carbon dioxide, sulfur dioxide and water, etc., without producing solid impurities. The particle impurities in the organic fertilizer waste gas will also produce inorganic residues after combustion, which will adhere to the inner wall of the incinerator and hinder heat transfer after a long time, affecting the incineration effect. Therefore, a more reasonable waste gas treatment device for organic fertilizer production waste gas is needed. SUMMARY

[0005] In view of the deficiencies in the prior art, the present utility model provides an organic fertilizer production waste gas treatment device, which solves the problem of inorganic residues produced by the combustion of particle impurities in the organic fertilizer production waste gas adhering to the inner wall of the incinerator, which will hinder heat transfer after a long time and affect the incineration effect.

[0008] Further, the top end of the furnace is provided with a receiving cavity, and the driving assembly is arranged corresponding to the receiving cavity, which includes a main gear coaxially arranged along the central axis of the furnace, a plurality of horizontal secondary gears are arranged corresponding to the outside of the main gear, the secondary gears are uniformly arranged around the main gear and meshed with the main gear, and an annular limit gear is arranged on the inner wall of the receiving cavity corresponding to the outer edge of the secondary gear, the teeth of the limit gear are located on the inner side and meshed with the secondary gear, so that the main gear, the secondary gear and the limit gear form a planetary gear structure.

[0009] Further, an annular groove corresponding to the circumferential movement range of the rotating shaft is arranged between the combustion chamber and the receiving cavity, so that the rotating shaft passes through the annular groove into the receiving cavity and is fixedly connected with the center of the secondary gear.

[0010] Further, a horizontal support is arranged at the bottom of the combustion chamber, the support is of a hollow structure, the outer edge of the support is rotationally connected to the inner wall of the furnace, and the top of the support is rotationally connected to the bottom end of the rotating shaft.

The outlet of the incinerator 1 is provided with a transfer pipe 3 connected to the inlet of the cyclone dust collector 2. The transfer pipe 3 is provided with a cooler 4. In this embodiment, a tubular air-cooled cooler 4 is used. That is, the organic fertilizer production waste gas first enters the incinerator 1 for incineration treatment. Then, the generated combustion waste gas is cooled before entering the cyclone dust collector 2. After separating particulate dust impurities, the remaining gas is discharged into the air.

[0022] As Figure 2 shown in the embodiment, the incinerator 1 is a vertically arranged cylindrical structure, including a cylindrical structure of the furnace body 11, the furnace body 11 is hollow to form a combustion chamber 12, the furnace body 11 is provided with an air inlet 13 on the top side to allow the exhaust gas to enter, the furnace body 11 is provided with a heater at the top end and an exhaust port 14 formed at the bottom end, and the heater in the embodiment is a natural gas combustion furnace. The combustion chamber 12 is also provided with a cleaning assembly inside to clean the inner wall of the furnace body 11.

[0023] In a specific scheme, the cleaning assembly includes six rotating shafts 5 arranged around the central axis of the furnace body 11 in the combustion chamber 12, the rotating shafts 5 are parallel to the central axis of the furnace body 11 and close to the inner wall of the furnace body 11, and the rotating shafts 5 are also provided with metal brushes 51, which are in close contact with the inner wall of the furnace body 11, so that when rotating, the dust attached to the inner wall of the furnace body 11 can be brushed off. The length of the rotating shaft 5 corresponds to the total length of the combustion chamber 12, and the metal brush 51 is arranged corresponding to the length of the rotating shaft 5, so that it covers the entire length of the inner wall of the furnace body 11 as much as possible, and then completely covers the vertical inner wall of the furnace body 11 during rotation. The top of the furnace body 11 is also provided with a driving assembly, which drives the rotating shaft 5 to rotate around the central axis of the furnace body 11 while simultaneously rotating around the rotating shaft 5 itself during rotation, so that the cleaning area of the metal brush 51 covers the entire inner wall of the furnace body 11.

[0024] As Figure 3 shown, in a further scheme, the top end of the furnace body 11 is provided with a receiving cavity, and the driving assembly is arranged corresponding to the receiving cavity, including a main gear 6 coaxially arranged horizontally along the central axis of the furnace body 11, six horizontal auxiliary gears 7 are arranged corresponding to the outside of the main gear 6, the auxiliary gears 7 are uniformly arranged around the main gear 6 and are in mesh with the main gear 6, and the inner wall of the receiving cavity is provided with an annular limiting gear 16 corresponding to the outer edge position of the auxiliary gear 7, the teeth of the limiting gear 16 are located on the inner side and are in mesh with the auxiliary gear 7, so that the main gear 6, the auxiliary gear 7 and the limiting gear 16 form a planetary gear structure. In the embodiment, the main gear 6 is an annular gear, which is arranged outside the burner 15, so as not to affect the work of the burner 15 during rotation.

[0025] Correspondingly, an annular groove corresponding to the circumferential movement range of the rotating shaft 5 is arranged between the combustion chamber 12 and the receiving cavity, so that the rotating shaft 5 passes through the annular groove into the receiving cavity and is fixedly connected with the center of the auxiliary gear 7. The bottom of the combustion chamber 12 is provided with a horizontal support 8, which is a hollow structure, the outer edge of the support 8 is rotationally connected to the inner wall of the furnace body 11, and the top of the support 8 is rotationally connected to the bottom end of the rotating shaft 5. Therefore, the rotating shaft 5 and the auxiliary gear 7 form an integrated structure, and when the auxiliary gear 7 rotates around the main gear 6 in a planetary manner, it also drives the rotating shaft 5 to rotate around the central axis of the furnace body 11 while rotating, so that the metal brush 51 can be cleaned by rotation and can cover the entire inner wall of the furnace body 11 by revolution.

[0026] As a suitable structure, a motor 63 is provided on the outside of the top of the furnace body 11. The motor 63 is vertically arranged, and its output shaft extends downward into the receiving cavity. The end of the output shaft is connected to a drive gear 62. A driven gear 61 is coaxially fixed above the main gear 6, and the drive gear 62 meshes with the driven gear 61. In this way, the rotation of the motor 63 can drive the rotating shaft 5 and the metal brush 51 to rotate and perform cleaning work.

[0027] like Figure 2 As shown, in a preferred embodiment, the furnace body 11 is further provided with a high-pressure nozzle 9. The high-pressure nozzle 9 is arranged around the inner wall of the furnace body 11, so that its jet direction is parallel to the central axis of the furnace body 11 and closely attached to the inner wall of the furnace body 11. One end of the high-pressure nozzle 9 extends out of the furnace body 11 and is connected to an air pump (not shown in the figure) through an air supply pipe 91. In this embodiment, the high-pressure nozzle 9 is located at the bottom of the furnace body 11, corresponding to the bottom surface of the support 8. Since the support 8 has a hollow structure, it will not affect the passage of the air ejected from the high-pressure nozzle 9, so that the high-pressure air can continuously scour the inner wall of the furnace body 11, further reducing the probability of powder adhering to the inner wall of the furnace body 11.
