Description

Technical Field

[0001] This utility model relates to the field of odor treatment, and in particular to a biological deodorization filter with self-cleaning function. Background Technology

[0002] In the field of biological deodorization, conventional biological deodorization filters mostly adopt a single-cavity structure with bottom air intake and top air outlet, where odors are degraded from bottom to top through the biological packing layer. However, the height of this conventional filter layer is generally around 1.6 meters, and the thickness of the single packing layer is too large. After long-term operation, the biological packing is prone to blockage due to pollutant deposition and excessive microbial proliferation, resulting in a significant increase in airflow resistance (pressure loss), a decrease in deodorization efficiency, and the need for frequent manual cleaning or replacement of the packing, which is cumbersome and costly. Some double-layer packing structures lack structures such as air backflushing and water backwashing. For example, Chinese utility model patent CN219424107U discloses a high-efficiency and energy-saving biological deodorization device, which only includes a pre-spray system, a central air distribution system, and a double-layer packing structure. It lacks a unique structure for the later maintenance and cleaning of the double-layer packing, resulting in significant packing wear in actual use. Utility Model Content

[0003] The purpose of this invention is to provide a biological deodorizing filter with self-cleaning function, which has both air backflushing and water backflushing capabilities.

[0004] The purpose of this utility model is achieved as follows: A biological deodorizing filter with self-cleaning function includes a filter body, and a partition is provided inside the filter body; the upper layer of the partition is an upper deodorizing layer, and the lower layer is a lower deodorizing layer; biological packing is provided in both the upper and lower deodorizing layers, and a set of spray pipes is provided above the biological packing in the upper and lower deodorizing layers; a set of backwashing high-pressure pipes is provided below the biological packing in the upper and lower deodorizing layers, and both sets of backwashing high-pressure pipes and both sets of spray pipes extend to the outside of the filter body and are connected to a main spray pipe; the main spray pipe is connected to a high-pressure water pump; a set of backflushing pipes is provided above the biological packing in the upper and lower deodorizing layers, and a set of air inlet pipes is provided below.

[0005] Preferably, the bottom of the filter body and the upper surface of the partition are set as inclined slopes.

[0006] Preferably, the main spray pipe is connected to a bottom flushing pipe, the bottom flushing pipe has branches, and the ends of the branches are located at the bottom of the filter body and the highest point of the partition.

[0007] Preferably, the filter body sidewall above the biological packing material is provided with an upper air outlet pipe, and the filter body sidewall below the biological packing material is provided with a lower air outlet pipe. The upper air outlet pipe and the lower air outlet pipe are connected to a blower for discharge.

[0008] Preferably, a sewage discharge pipe is provided at the bottom of the filter body below the biological packing material and at the lowest point of the partition.

[0009] Preferably, the two sets of backflush pipes are connected to the external main backflush pipe, and the two sets of air intake pipes are connected to the external main air intake pipe; both the main backflush pipe and the main air intake pipe are connected to the air intake.

[0010] Preferably, control valves are provided on the main backflush pipe, main air inlet pipe, bottom flushing pipe, backflush high-pressure pipe, upper air outlet pipe, sewage discharge pipe, lower air outlet pipe, and the main spray pipe located between the spray pipe and the backflush high-pressure pipe.

[0011] Preferably, the organism is 0.8-1M.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The traditional 1.6-meter single-layer height is divided into two layers (each biological layer is 0.8-1 meters), which shortens the thickness of the packing layer. This allows air backflushing and water backwashing to be applied evenly to each packing layer, effectively solving the problem of deep blockage that is difficult to clean and improving pressure loss control.

[0014] 2. The air-water self-cleaning system, consisting of spray pipes, backwash high-pressure pipes, and backflush pipes, can automatically flush the surface and gaps of the packing material regularly, reducing the frequency of manual cleaning. Attached Figure Description

[0022] like Figure 1 As shown, a self-cleaning biological deodorizing filter includes a filter body 1, with a baffle 2 inside the filter body 1. The upper layer of the baffle 2 is an upper deodorizing layer 3, and the lower layer is a lower deodorizing layer 4, resulting in more efficient double-layer biological deodorization. Both the upper deodorizing layer 3 and the lower deodorizing layer 4 are equipped with biological packing material 5. Above the biological packing material 5 in both the upper and lower deodorizing layers 3 and 4, there is a set of spray pipes 6. Below the biological packing material 5 in both the upper and lower deodorizing layers 3 and 4, there is a set of backwashing high-pressure pipes 7. Both sets of backwashing high-pressure pipes 7 and both sets of spray pipes 6 extend to the outside of the filter body and connect to a main spray pipe 8. The backwashing high-pressure pipes remove impurities deposited between the packing material through high-pressure water flow, preventing blockage and ensuring smooth airflow. The main spray pipe 8 is connected to a high-pressure water pump 9. Above the biological packing material 5 in both the upper and lower deodorizing layers 3 and 4, there is a set of backflushing pipes 10, and below, there is a set of air inlet pipes 11.

[0023] like Figure 1 As shown, the bottom of the filter body 1 and the upper surface of the baffle 2 are set as inclined slopes 12 to guide impurities out of the filter body.

[0024] like Figure 1 As shown, the main spray pipe 8 is connected to the bottom flushing pipe 13. The bottom flushing pipe 13 is provided with a branch 1301. The end of the branch 1301 is located at the bottom of the filter body 1 and the highest point of the partition 2, so that the water flow can flush the impurities to the lowest point.

[0025] like Figure 1 As shown, the filter body sidewall above the biological packing material 5 is provided with an upper air outlet pipe 14, and the filter body sidewall below the biological packing material 5 is provided with a lower air outlet pipe 15 and a backflush air outlet pipe 21. The upper air outlet pipe 14 and the lower air outlet pipe 15 are connected to the blower and discharged.

[0026] like Figure 1 As shown, a sewage discharge pipe 16 is provided at the bottom of the filter body 1 below the biological packing material 5 and at the lowest point of the partition 2; sewage is discharged in conjunction with the inclined structure.

[0027] like Figure 1 As shown, the two sets of backflush pipes 10 are connected to the external main backflush pipe 17, and the two sets of air inlet pipes 11 are connected to the external main air inlet pipe 18; the main backflush pipe 17 and the main air inlet pipe 18 are both connected to the air inlet 19; to reduce the complexity of the equipment, they share a single air inlet.

[0028] like Figure 1 As shown, control valves 20 are provided on the main backflush pipe 17, the main air inlet pipe 18, the bottom flush pipe 13, the backflush high-pressure pipe 7, the upper air outlet pipe 14, the sewage discharge pipe 16, the lower air outlet pipe 15, and the main spray pipe 8 located between the spray pipe 8 and the backflush high-pressure pipe 7. Each pipe is equipped with an independent control valve, which can quickly shut off the corresponding pipe. At the same time, automatic cleaning can be achieved in conjunction with the differential pressure gauge in the attached figure. When the differential pressure exceeds the set value, the cleaning function is automatically activated.

[0029] like Figure 1 As shown, the height of the biological packing material 5 is less than 0.8-1M to avoid excessive airflow resistance due to excessive packing thickness, thereby improving deodorization efficiency and also increasing the efficiency of backflushing and high-pressure rinsing.

[0030] The working principle of this invention is explained as follows: Exhaust gas enters the upper and lower deodorization layers through the main inlet pipe and the inlet pipe respectively. As it passes through the biological packing material, it is degraded by microorganisms, and the purified gas is discharged through the upper and lower outlet pipes. During cleaning, a high-pressure water pump drives the main spray pipe to impact and unclog the deep layers from below via the backwash high-pressure pipe. Air is introduced through the backflushing pipe to assist in removing particles from the gaps in the packing material. The inclined surfaces at the bottom of the filter tank and the baffles allow wastewater impurities to automatically flow to the sewage discharge pipe for discharge. Control valves on each pipe enable mode switching, greatly improving deodorization efficiency and reducing maintenance costs.

[0031] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
