Description

Technical Field

[0001] This utility model relates to the field of odor treatment, and in particular to an odor treatment device. Background Technology

[0002] Garbage odor control is an important part of urban environmental sanitation management. It is mainly aimed at reducing or eliminating odors generated during garbage collection, transportation, storage and treatment, and improving the quality of the surrounding environment. At present, biological treatment methods are commonly used to treat odors.

[0003] Odor treatment devices in related technologies typically include an odor control tower, with biological packing material installed in the middle. The lower end of the odor control tower is connected to an air inlet pipe, the top is connected to an exhaust pipe, and the bottom is connected to a drain pipe. A spray pipe is installed inside the odor control tower above the biological packing material.

[0004] However, odors often contain dust and impurity particles. When the odor moves upward in the deodorization tower and passes through the biological packing material, the dust and impurity particles may adhere to the surface of the biological packing material. Over time, this may cause blockage of the pores of the biological packing material, resulting in poor water and air circulation. This will affect the growth and reproduction of microorganisms in the biological packing material, and thus affect the odor treatment effect, which needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an odor treatment device that can pre-treat dust and impurity particles in odor, reduce the risk of dust and impurity particles entering the biological packing material, thereby reducing the risk of pore blockage of the biological packing material, so as to ensure the growth and reproduction of microorganisms and thus ensure the odor treatment effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an odor treatment device, including an odor tower, biological packing material, an air inlet pipe, an exhaust pipe, a drain pipe, and a spray pipe. The bottom of the odor tower is open, and a treatment box is connected to the bottom of the odor tower. The air inlet pipe and the drain pipe are respectively connected to the treatment box, and a filling pipe is connected to the upper end of the treatment box.

[0007] The treatment tank is equipped with a pretreatment pipe, and the height of the pretreatment pipe is lower than the water level in the treatment tank. One end of the pretreatment pipe is connected to the air inlet pipe, and the other end is sealed. Multiple exhaust holes are evenly arranged on the treatment pipe.

[0008] Optionally, the pretreatment tube is arranged in a curved shape.

[0009] Optionally: A foam breaking screen is horizontally arranged inside the treatment tank. The foam breaking screen is located above the pretreatment pipe and below the water level in the treatment tank, and the aperture of the mesh of the foam breaking screen is much smaller than the aperture of the vent hole.

[0010] Optionally: the treatment box and the deodorization tower are detachably connected via a pair of sealing flanges, the foam breakage net is detachably connected to the treatment box, and the foam breakage net can be removed from the treatment box after the treatment box is removed from the bottom of the deodorization tower.

[0011] Optionally: A limiting ring is fixedly connected to the inner wall of the processing box along its circumference, and the broken foam net is placed on the limiting ring and connected to the limiting ring by a plurality of fastening screws.

[0012] Optionally, a one-way valve is provided inside the air intake pipe, and the one-way valve is used to restrict the odor gas to enter the pretreatment pipe only through the air intake pipe.

[0013] Optionally, the processing box is provided with an observation window.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This odor treatment device allows odor to first enter the treatment chamber and then the deodorization tower. This means that dust and impurity particles in the odor can enter the water in the treatment chamber, thus achieving pretreatment of dust and impurity particles in the odor. This reduces the risk of dust and impurity particles entering the biological packing material, thereby reducing the risk of pore blockage of the biological packing material, ensuring the growth and reproduction of microorganisms, and thus ensuring the odor treatment effect.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 , Figure 2An odor treatment device includes a deodorization tower 1, a biological packing material 2 disposed in the middle of the deodorization tower 1, a spray pipe 3 disposed inside the deodorization tower 1 above the biological packing material 2, and the spray pipe 3 being connected to an external water supply pipe. Meanwhile, an exhaust pipe 4 is connected to the top of the deodorization tower 1.

[0022] Reference Figure 1 , Figure 2 The bottom of the deodorization tower 1 is open, and a treatment box 5 is connected to the bottom of the deodorization tower 1. The upper end of the treatment box 5 is connected to a filling pipe 6, and the lower end is connected to an air inlet pipe 7 and a drain pipe 8. At the same time, solenoid valves are installed on the filling pipe 6 and the drain pipe 8 respectively to control the opening and closing of the corresponding pipes.

[0023] Reference Figure 1 , Figure 3 The treatment tank 5 is equipped with a pretreatment pipe 9, which is curved and its height is lower than the water level in the treatment tank 5. At the same time, one end of the pretreatment pipe 9 is connected to the air inlet pipe 7, and the other end is sealed. Multiple exhaust holes 10 are evenly arranged on the treatment pipe.

[0024] Reference Figure 2 , Figure 3 A foam breaker 11 is horizontally installed inside the treatment tank 5. The foam breaker 11 is located above the pretreatment pipe 9 and below the water level in the treatment tank 5. The aperture of the foam breaker 11 is much smaller than the aperture of the vent 10. In this embodiment, the aperture of the foam breaker 11 is about one-tenth the aperture of the vent 10. Meanwhile, an observation window 12 is provided on the treatment tank 5 to facilitate observation of the water level inside the treatment tank 5 by the operator.

[0025] In this embodiment, the pretreatment pipe 9 is located at the lower end of the treatment tank 5, the foam breaker 11 is located in the middle of the treatment tank 5, and the initial water level is about three-quarters of the depth of the treatment tank 5 so that the water can completely submerge the foam breaker 11.

[0026] When odor needs to be treated, clean water is injected into the treatment tank 5 through the injection pipe 6 until the water level is about three-quarters of the depth of the treatment tank 5. Then the control valve on the injection pipe 6 is closed. At the same time, water is supplied to the spray pipe 3 through the external water supply pipe. The atomizing nozzle on the spray pipe 3 atomizes the clean water and sprays it out.

[0027] Subsequently, the odor is delivered to the air inlet pipe 7 through an external air source. At this time, the odor enters the pretreatment pipe 9 and is discharged into the clean water in the treatment tank 5 through multiple exhaust holes 10. During this process, the dust and impurity particles in the odor can enter the clean water, thereby achieving the pretreatment of the dust and impurity particles in the odor.

[0028] As the odorous gas enters the clean water in the treatment tank 5, it forms bubbles and rises. When the larger bubbles pass through the bubble-breaking net 11, they are broken into multiple smaller bubbles, thereby increasing the contact area between the odorous gas and the clean water and improving the pretreatment effect on dust and impurity particles in the odorous gas. Subsequently, the pretreated odorous gas continues to rise and undergoes biological reaction treatment with the biological packing material 2, and is finally discharged through the exhaust pipe 4.

[0029] As the spray pipe 3 continuously sprays clean water into the deodorization tower 1, the clean water will enter the treatment tank 5. When treating the odor, the staff can check the water level in the treatment tank 5 through the observation window 12. If the water level is about to reach the capacity limit of the treatment tank 5, the solenoid valve on the drain pipe 8 will be opened to drain the excess water in the treatment tank 5.

[0030] Reference Figure 2 , Figure 3 The treatment box 5 and the deodorization tower 1 are detachably connected via a pair of sealing flanges 13. The broken foam net 11 is also detachably connected to the treatment box 5. After the treatment box 5 is removed from the bottom of the deodorization tower 1, the broken foam net 11 can be removed from the treatment box 5, facilitating cleaning and other operations by staff. A limiting ring 14 is fixedly connected to the inner wall of the treatment box 5 along its circumference. The broken foam net 11 rests on the limiting ring 14 and is connected to the limiting ring 14 by multiple fastening screws, allowing for quick disassembly of the broken foam net 11.

[0031] Reference Figure 1 A one-way valve (not shown in the figure) is installed in the air inlet pipe 7. The one-way valve is used to restrict the odor to enter the pretreatment pipe 9 only through the air inlet pipe 7, so as to prevent the water in the treatment box 5 from flowing back to the air inlet pipe 7, thereby improving the stability of the odor treatment device.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
