Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leachate treatment, in particular to an aeration pipe cooling device. Background Art
[0002] In the leachate treatment process, there are a large number of aerobic microorganisms inside the digester. Aerobic microorganisms will generate a lot of heat during digestion, which will cause the temperature inside the digester to rise. The increase in digester temperature will also affect the living environment of aerobic microorganisms.
[0003] When the temperature in the digester affects the life of aerobic microorganisms, the digester needs to be cooled. A Roots blower is used to blow aeration into the digester through the aeration pipe to cool the digester to provide the growth needs of aerobic microorganisms.
[0004] However, when the Roots blower is running, its outlet temperature is high, which makes the gas temperature inside the aeration pipe high and cannot be directly discharged into the aeration tank. The prior art uses a cooling device to cool the gas inside the aeration pipe before discharging it into the digester. Since the Roots blower continues to run, its outlet temperature will continue to rise. The cooling method in the prior art gradually cannot meet its cooling needs, so a new cooling device is needed. Summary of the invention
[0005] In order to solve the problem that as the Roots blower continues to run, the cooling method in the prior art gradually cannot meet the need for cooling, the utility model proposes an aeration pipe cooling device, which cools the aeration pipe through a heat exchange component and a spray component to reduce the outlet temperature of the Roots blower.
[0006] In order to achieve the above purpose, the technical solution of the utility model is:
[0007] An aeration pipe cooling device comprises an aeration pipe body, on which a cooling component is arranged, and the cooling component comprises a heat exchange component and a spray component;
[0008] The heat exchange assembly includes a heat exchange tube and a fixing clamp located outside the heat exchange tube. The heat exchange tube is wound around the outside of the aeration tube body. One end of the heat exchange tube passes through the lower side of the fixing clamp to form a water inlet. The other end of the heat exchange tube passes through the upper side of the fixing clamp to form a water outlet.
[0009] The spray assembly includes an annular spray pipe and a water receiving tray, the water receiving tray is located above the fixing clamp, a return hole is provided on one side of the water receiving tray, a return pipe is connected to the outer side of the return hole, the spray pipe is located above the water receiving tray, a water inlet 2 is provided at one end of the spray pipe, a spray port is opened at the bottom of the spray pipe, and a slow flow component is provided between the water receiving tray and the spray pipe.
[0010] Furthermore, a collecting tray is provided above the spray pipe, and the collecting tray is fixedly connected to the aeration pipe body.
[0011] Furthermore, the flow-slowing member is a strip-shaped structure, the flow-slowing member is wound around the outside of the aeration pipe body in a serpentine shape, and the flow-slowing member is a strip-shaped structure made of a spring.
[0012] Furthermore, a nozzle is provided at the spray port, and the nozzle is aimed at the aeration pipe body.
[0013] Furthermore, the spray pipe is annularly sleeved outside the aeration pipe body.
[0014] Furthermore, a joint is provided at the water outlet, and the connecting pipe is connected to the heat exchange pipe through the joint.

[0017] Through the above technical solution, the beneficial effects of the utility model are:
[0018] The utility model arranges a heat exchange component and a spray component on an aeration pipe body at the outlet of a Roots blower. When the outlet temperature of the Roots blower is high, the heat exchange component is used to exchange heat on the aeration pipe body, and then the spray component is used to cool the aeration pipe body, thereby reducing the temperature of the aeration pipe body at the outlet of the Roots blower and reducing the temperature of the gas inside the aeration pipe.
[0019] The utility model can recycle water resources to the maximum extent and avoid the waste of water resources by arranging the water receiving tray and the collecting tray.

[0031] The heat exchange assembly includes a heat exchange tube 2 and a fixing clamp 3 located outside the heat exchange tube 2. The heat exchange tube 2 is wound around the outside of the aeration tube body 1. One end of the heat exchange tube 2 passes through the lower side of the fixing clamp 3 to form a water inlet 4, and the other end of the heat exchange tube 2 passes through the upper side of the fixing clamp 3 to form a water outlet.
[0032] The spray assembly includes an annular spray pipe 5 and a water receiving tray 6, the water receiving tray 6 is located above the fixing clamp 3, a reflux hole is provided on one side of the water receiving tray 6, a reflux pipe 7 is connected to the outer side of the reflux hole, the spray pipe 5 is located above the water receiving tray 6, a water inlet 2 is provided at one end of the spray pipe 5, a spray port is opened at the bottom of the spray pipe 5, and a slow flow component 9 is provided between the water receiving tray 6 and the spray pipe 5.
[0033] In addition, a collecting tray 10 is provided above the spray pipe 5 and fixedly connected to the aeration pipe body. Water vapor is collected by the collecting tray 10 and condensed into water droplets when encountering the spray pipe 5 and dripping into the water receiving tray 6 to recycle water resources.
[0034] Specifically, the flow slowing member 9 is a strip structure, which is serpentinely wound around the outside of the aeration pipe body 1. The flow slowing member 9 is a strip structure made of a spring. By setting the flow slowing member 9, the flow speed of the spray water outside the aeration pipe body 1 is slowed down, so that the spray water can fully exchange heat with the aeration pipe body 1, thereby improving the heat exchange efficiency.
[0035] In this embodiment, a spray head 11 is provided at the spray port, and the spray head 11 is aimed at the aeration pipe body 1 . The spray pipe 5 sprays water to the aeration pipe body 1 to cool the aeration pipe body 1 .
[0036] In this embodiment, the spray pipe 5 is annularly sleeved on the outside of the aeration pipe body 1 to facilitate spraying the outside of the aeration pipe body 1.
[0037] In this embodiment, a joint 12 is provided at the water outlet to facilitate connection with the connecting pipe 8 , and the connecting pipe 8 is connected to the heat exchange pipe 2 through the joint 12 .
[0038] In this embodiment, the fixing clamp 3 includes a clamp plate 1 and a clamp plate 2, and the clamp plate 1 and the clamp plate 2 jointly clamp the heat exchange tube 2. The clamp plate 1 and the clamp plate 2 are fixedly connected by bolts, and the heat exchange tube 2 is fitted to the aeration tube body 1 through the clamp plate, thereby ensuring the heat exchange efficiency.

The slow-flow member 9 on the surface of the aeration pipe body 1 will reduce the flow rate of the cooling water, increase the contact time between the cooling water and the aeration pipe body 1, and improve the cooling effect. The cooling water is finally collected through the water receiving tray 6 to avoid waste of resources.
