Description

Technical Field

[0001] The present invention belongs to the technical field of sludge treatment, and more specifically, relates to a device for chemically oxidizing and digesting organic sludge in a reactor. Background Art

[0002] The sludge produced by municipal sewage treatment plants can be regarded as a concentrate of pollutants in municipal domestic sewage. If not properly treated, it is very easy to cause secondary pollution. It is estimated that at present, the daily treatment of municipal domestic sewage in China exceeds 220 million tons. Calculated according to the sludge production rate, the daily production of filtered sludge by national municipal sewage treatment plants exceeds 200,000 tons. For such a huge volume of sludge, the treatment will surely consume huge costs. Therefore, exploring and researching new sludge treatment methods is an effective way to reduce the sludge treatment cost and reduce secondary pollution in sludge treatment, which meets the requirements of ecological civilization construction.

[0003] At present, using chemical agents to digest organic sludge is one of the common methods for organic sludge treatment. The process of chemically digesting organic sludge usually involves first putting the agent into the sludge pool, and then mixing the agent and sludge through stirring to cause a chemical reaction, oxidizing the organic sludge into reaction gases such as water and carbon dioxide, so as to achieve the digestion of organic sludge. However, in the above process, part of the agent will volatilize and escape with the generated reaction gas, resulting in a decrease in the use efficiency of the agent and an increase in the operation cost.

[0051] Please refer to Figure 1 , and now an organic sludge chemical oxidation digestion reactor device provided by the present invention will be described. The organic sludge chemical oxidation digestion reactor device includes a sludge tank 1, a chemical agent tank 2, a stirring air pipe 3, a stirring air blower 4, a three-phase separator, and a gas collecting pipe. Among them, the sludge tank 1 is used to place the sludge water body. The chemical agent tank 2 transports the chemical agent to the bottom of the sludge tank 1 through a chemical agent delivery pipe 21. The stirring air pipe 3 is arranged at the bottom of the sludge tank 1. A plurality of air outlet groups are provided on the stirring air pipe 3. The exhaust end of the stirring air blower 4 is connected to the stirring air pipe 3 for delivering compressed air to the stirring air pipe 3. The three-phase separator is arranged in the sludge tank 1 and is located inside the sludge water body. The three-phase separator is used to separate the sludge water body to form an aqueous phase aggregation area 101, a sludge phase aggregation area 102, and a gas phase aggregation area 103 in the sludge tank 1. One end of the gas collecting pipe is communicated with the gas phase aggregation area 103, and the other end of the gas collecting pipe is connected to the suction end of the stirring air blower 4.

[0052] An organic sludge chemical oxidation digestion reactor device provided by the present invention, compared with the prior art, by arranging a three-phase separator in the sludge tank 1, an aqueous phase aggregation area 101, a sludge phase aggregation area 102 and a gas phase aggregation area 103 can be formed in the sludge tank 1. Then, by arranging a gas collecting pipe, one end of the gas collecting pipe is connected to the gas phase aggregation area 103, and the other end of the gas collecting pipe is connected to the suction end of the stirring air blower 4. In this way, the waste gas containing volatile agents accumulated in the gas phase aggregation area 103 can be discharged to the bottom of the sludge tank 1 through the stirring air blower 4 and the stirring air pipe 3, so that the volatilized agent can react with the sludge water body in the sludge tank 1 again, thereby improving the use efficiency of the agent and reducing the operation cost.

[0053] In this embodiment, the sludge tank 1 is a square tank structure with an upward opening. The sludge water body to be treated can be put into the sludge tank 1 through the opening above the sludge. In application, the reagent tank 2 can be arranged on one side of the sludge tank 1. A medicine delivery pipe 21 is provided on the reagent tank 2. The medicine discharge end of the medicine delivery pipe 21 can be placed into the bottom of the sludge tank 1 through the opening on the sludge tank 1. A power pump 22 is connected in series on the medicine delivery pipe 21. The reagent in the reagent tank 2 can be pumped into the sludge tank 1 through the power pump 22.

[0054] In some embodiments, please refer to Figure 1 , the above-mentioned three-phase separator includes an inverted V-shaped separation cover 51 and a separation plate 52. The separation cover 51 is centrally connected between the front side wall and the rear side wall of the sludge tank 1. The number of separation plates 52 is two. The two separation plates 52 are respectively connected between the front side wall and the rear side wall of the sludge tank 1 and are symmetrically arranged on the left and right sides of the separation cover 51. The upper end of the separation plate 52 is located above the lower end of the separation cover 51 and is connected to the side wall on the same side in the sludge tank 1. The lower end of the separation plate 52 is inclined towards the separation cover 51 and extends below the separation cover 51. An overflow channel 53 for the reaction water to pass through is provided between the separation cover 51 and the separation plate 52. In application, when the airflow discharged from the stirring air pipe 3 drives the sludge water body to roll up and down, the reagent and the organic sludge in the sludge water body are mixed and reacted. The reaction water generated by the reaction will overflow to the upper part of the separation cover 51 and the separation plate 52 through the above-mentioned overflow channel 53, so as to form an aqueous phase aggregation area 101 above the separation cover 51 and the separation plate 52. The sludge remaining after the reaction in the sludge water body will collide with the separation cover 51 and the separation plate 52 during the upward flow with the water and then settle back to the bottom of the sludge tank 1 under the action of gravity, so as to form a sludge phase aggregation area 102 below the separation cover 51 and the separation plate 52. The reaction gas generated during the reaction will accumulate on the inner side of the top of the separation cover 51 and the inner side of the top of the separation plate 52, so as to form a gas phase aggregation area 103 between the top of the separation cover 51 and the sludge phase aggregation area 102 and between the top of the separation plate 52 and the sludge phase aggregation area 102.

[0055] In this embodiment, please refer to Figure 1 , the above-mentioned gas collecting pipe includes a main gas collecting pipe 61 and gas collecting branch pipes 62. Among them, a first exhaust end and a second exhaust end are provided on the main gas collecting pipe 61. The first exhaust end is connected to the suction end of the stirring fan 4 through a first control valve 611, and the second exhaust end is connected to the waste gas treatment system through a second control valve 612. The number of gas collecting branch pipes 62 is three, and the three gas collecting branch pipes 62 are all connected to the main gas collecting pipe 61. The intake end of one of the gas collecting branch pipes 62 penetrates through the top of the separation cover 51 and communicates with the gas phase aggregation area 103, and the other two gas collecting branch pipes 62 respectively penetrate through the tops of the two separation plates 52 and communicate with the gas phase aggregation area 103. In this embodiment, the gas collecting branch pipes 62 are used to guide the reaction gas aggregated in the gas phase aggregation area 103 into the main gas collecting pipe 61. In practical applications, in the early stage of the reaction, the volatilization amount of the reagent is large, so the first control valve 611 is opened and the second control valve 612 is closed, so that the reaction gas in the gas phase aggregation area 103 can be circulated and reacted with the sludge water body through the stirring fan 4 and the stirring gas pipe 3, thereby improving the reagent utilization rate. In the later stage of the reaction, after the stirring fan 4 and the stirring gas pipe 3 stop working, the first control valve 611 can be closed and the second control valve 612 can be opened, so that the reaction gas generated in the later stage of the reaction can be discharged into the waste gas treatment system for centralized treatment, thereby avoiding environmental pollution caused by the overflow of the reaction gas.

[0056] In some embodiments, please refer to Figure 1 , an overflow water outlet 104 is provided on the side wall of the sludge tank 1. The overflow water outlet 104 is arranged above the three-phase separator.

Each air outlet group includes two hole bodies 311 penetrating the side wall of the operation section 31, and the two hole bodies 311 in the same air outlet group are symmetrically arranged on the left and right sides of the operation section 31. A plugging component is slidably arranged on the operation section 31 corresponding to each air outlet group. The plugging component slides to block or avoid the hole body 311. In application, when it is necessary to perform air flow stirring operation on the operation section 31, the plugging component slides to the first position to avoid the hole body 311, so that the compressed air in the operation section 31 is sprayed into the sludge tank 1 through the hole body 311. When the operation section 31 stops the air flow stirring operation, the plugging component slides to the second position to block the hole body 311, thereby preventing the sludge water body from invading the operation section 31 through the hole body 311 and reducing the accident rate of the sludge water body blocking the operation section 31.

[0058] In this embodiment, please refer to Figures 1 to 9 , at the bottom of the sludge tank 1, a plurality of support columns 106 are arranged along the length direction of the operation section 31.

A plurality of sleeves 7 are connected to the driving rod 8 through a dial 71. The first driver is arranged at one end of the axis side of the driving rod 8. The first driver is used to drive the driving rod 8 to reciprocate along its axis to drive the sleeve 7 to slide between the first position and the second position on the operation section 31 to avoid or block the hole body 311 on the operation section 31.

[0059] In this embodiment, please refer to Figures 1 to 9 , the upper end of the dial 71 is provided with a first through hole 711 adapted to the driving rod 8, and the lower end of the dial 71 is provided with a second through hole 712 adapted to the sleeve 7.

[0060] In this embodiment, a receiving groove 107 is provided on the side wall of the sludge tank 1 on the axial side corresponding to the working section 31. A sealing plate 10 is provided at the opening of the receiving groove 107. One end of the driving rod 8 is connected with a rotating rod 81.

There is a moving distance between the electromagnet 20 and the magnetic block 82. When the electromagnet 20 is energized, it will attract the magnetic block 82 to move towards the electromagnet, and the first spring 83 is stretched. The magnetic block 82 drives the driving rod 8 to move through the rotating rod 81, so that the driving rod 8 can drive the sleeve 7 to move to the first position, and the sleeve 7 avoids the hole body 311. When the electromagnet 20 is powered off, the first spring 83 contracts to drive the magnetic block 82 to reset. The magnetic block 82 drives the driving rod 8 to perform a reset movement through the rotating rod 81, so that the driving rod 8 can drive the sleeve 7 to move to the second position, and the sleeve 7 closes the hole body 311.

[0061] In some embodiments, please refer to Figures 1 to 9 , a flow guiding plate 75 is provided corresponding to the hole body 311 at one end of the sleeve 7 close to the hole body 311.

[0062] In some embodiments, please refer to Figures 1 to 9 , the sleeve 7 and the working section 31 can rotate relative to each other. A square prism section 701 is provided on the side of the sleeve 7 close to the hole body 311. The flow guiding plates 75 are arranged on the four side walls of the square prism section 701. The four flow guiding plates 75 include two first plate bodies 751 and two second plate bodies 752. Among them, the included angle between the first plate body 751 and the working section 31 is different from the included angle between the second plate body 752 and the working section 31, and the first plate body 751 and the second plate body 752 are arranged oppositely. An intermittent driving mechanism is connected to one end of the driving rod 8. A transmission component for driving the sleeve 7 to rotate is provided between the driving rod 8 and the sleeve 7. In this embodiment, the transmission component includes a sprocket 73 sleeved on the driving rod 8 and the sleeve 7 respectively and a chain 74 wound around the two sprockets 73. The above intermittent driving mechanism intermittently drives the driving rod 8 to rotate, and the sleeve 7 can be driven to rotate intermittently by means of the transmission component, so that the first plate body 751 and the second plate body 752 alternately guide the air flow ejected from the hole body 311.

[0063] Specifically, the above intermittent drive mechanism includes a first gear 84, a half gear 85, and a motor 30. Among them, the first gear 84 is arranged at the end of the drive rod 8 close to the rotating rod 81, and the first gear 84 is fixedly connected to the drive rod 8.

In application, when the electromagnet 20 is energized and the sleeve 7 moves to the first position, the first gear 84 moves to a predetermined position. At this time, the first gear 84 is aligned with the half gear 85, and the first gear 84 and the half gear 85 enter the working state. The motor 30 drives the half gear 85 to rotate, and the half gear 85 intermittently meshes with the first gear 84 to drive the drive rod 8 to rotate intermittently, so that the drive rod 8 intermittently drives the sleeve 7 to rotate through the transmission component. When the electromagnet 20 is de-energized and the sleeve 7 moves to the second position, the first gear 84 and the half gear 85 are arranged in an interleaved manner, and the first gear 84 and the half gear 85 exit the working state.

[0064] In this embodiment, the number of teeth on the above half gear 85 is 1 / 4 of the number of teeth on the first gear 84. By setting it in this way, the angle by which the half gear 85 drives the first gear 84 to rotate each time can be 90°, so that the angle by which the sleeve 7 rotates each time is also 90°. In this embodiment, the number of hole bodies 311 corresponding to each sleeve 7 is two, and the two hole bodies 311 are respectively arranged on the left and right sides of the working section 31. When the two hole bodies 311 are performing the air flow stirring operation, one of them corresponds to the first plate body 751 or the second plate body 752. Since the inclination angles of the first plate body 751 and the second plate body 752 relative to the working section 31 are different, the transmission angles of the air flows ejected from the two hole bodies 311 after passing through the flow guide plate 75 are different, so that the flow directions and flow velocities of the sludge water bodies on the left and right sides of the working section 31 are different. In this way, the turbulence in the sludge water body is greatly increased, and the stirring effect is improved. In this embodiment, by arranging two first plate bodies 751 and two second plate bodies 752 on the square prism section 701 and making the sleeve 7 rotate intermittently by 90°, the first plate body 751 and the second plate body 752 can alternately correspond to each hole body 311, and further, the transmission angles of the air flows ejected from each hole body 311 can be intermittently changed, so as to increase the turbulence in the sludge water body and improve the stirring effect.

[0065] In some embodiments, please refer to Figure 1 and Figure 10, a sealing sleeve 9 is provided at the end of the working section 31. A connecting groove 901 is provided in the middle of the sealing sleeve 9. A piston 91 is slidably arranged in the connecting groove 901. A second spring 93 is provided between the piston 91 and the bottom of the connecting groove 901. A proximity switch 94 is provided at the bottom of the connecting groove 901. The proximity switch 94 is used to control the opening and closing of the electromagnet 20 and the motor 30. A trigger block 92 is provided at one end of the piston 91 facing the bottom of the connecting groove 901. In application, the working section 31 is inserted into the connecting groove 901 and is hermetically connected to the connecting groove 901. The working section 31 communicates with the connecting groove 901. When the stirring fan 4 supplies air into the working section 31, the air pressure in the working section 31 gradually increases. The compressed air flow drives the piston 91 to move towards the proximity switch 94 side and compresses the second spring 93, so that the trigger block 92 triggers the proximity switch 94, and then the electromagnet 20 and the motor 30 can be turned on. When the stirring fan 4 stops supplying air into the working section 31, the air pressure in the working section 31 drops. The contraction of the second spring 93 drives the piston 91 to drive the trigger block 92 away from the proximity switch 94, and the electromagnet 20 and the motor 30 are turned off.

[0066] In application, when the stirring fan 4 is just started, the air pressure in the working section 31 is small. If the electromagnet 20 is in the energized state and the sleeve 7 is in the first position at this time, the air flow ejected through the hole body 311 will have a problem of insufficient power due to the small pressure, and the sludge water body is likely to invade the working section 31 through the hole body 311. In this embodiment, when the stirring fan 4 is turned on, the electromagnet 20 will not be immediately energized. Instead, after the air pressure in the working section 31 rises, the piston 91 is pushed by the air flow to compress the second spring 93, so that the trigger block 92 triggers the proximity switch 94, and then the electromagnet 20 will be energized to make the sleeve 7 avoid the hole body 311. At this time, the pressure in the working section 31 is relatively large, and the air flow ejected from the hole body 311 has sufficient power, which can prevent the sludge water body from invading the working section 31 through the hole body 311. On the other hand, when the air pressure in the working section 31 becomes small and the air flow power is insufficient, the second spring 93 will drive the trigger block 92 away from the proximity switch 94, so that the electromagnet 20 is de-energized, and the sleeve 7 can timely block the hole body 311 on the working section 31.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
