Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a biological filtering and deodorizing device. Background Art

[0002] Biodeodorization is a technology that uses the metabolic activities of microorganisms to decompose and remove malodorous gases. This technology is usually used to treat malodorous gases generated by industrial emissions, landfills, sewage treatment plants, animal husbandry, etc. The basic principle of biodeodorization is to use specific microbial flora (such as bacteria, fungi, etc.) to decompose and transform organic compounds in malodorous gases into harmless substances such as water and carbon dioxide.

[0003] Announcement No. CN220758676U discloses an improved deodorizing tower, which increases the contact time of waste gas inside the deodorizing tower and improves the deodorizing effect of waste gas through a multi-layer mounting plate and filler structure. At the same time, the mounting block and slide groove structure facilitate the installation and disassembly of the mounting plate, facilitates the subsequent replenishment and replacement of the filler, and ensures the deodorizing effect when the device is used.

[0004] However, in the above scheme, since the internal space of the deodorizing tower is relatively large, the exhaust gas enters the deodorizing tower through the air inlet pipe, resulting in relatively concentrated exhaust gas emissions, making it difficult for the exhaust gas to fully contact the filler, resulting in dead corners of contact and wasting the filler.

[0005] Therefore, we propose a biological filtration and deodorization device to solve the above problems. Utility Model Content

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] By staggeredly arranging a plurality of partitions inside the deodorizing box, an S-shaped airway is formed between the plurality of partitions for the exhaust gas to flow through, thereby reducing the exhaust area. At the same time, the S-shaped airway increases the retention time of the exhaust gas in the deodorizing box, making its contact with the filler more uniform. The filler layer is composed of a plurality of filler blocks.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-3 As shown, the utility model provides a biological filtration deodorization device, comprising a spray box 1 with a spray mechanism therein and a deodorization box 2, an air inlet pipe 6 is arranged at one end of the spray box 1, the spray box 1 and the deodorization box 2 are connected through a connecting pipe 7, and an air outlet pipe 8 is arranged at the top of the spray box 1;

[0030] The spray mechanism includes a liquid inlet pipe 31, the water outlet end of the liquid inlet pipe 31 passes through the top wall of the spray box 1 and is provided with a liquid separation plate 32, on which a plurality of atomizing nozzles 33 are provided, and a waste liquid port 9 is provided on one side of the bottom of the spray box 1, and a valve is provided on the waste liquid port 9.

[0031] The spray mechanism can spray specific deodorants or chemical solutions to dissolve and dilute the odor source before the exhaust gas enters the deodorization box, thereby reducing the concentration of the odor.

[0032] A plurality of partitions 41 are alternately arranged on the left and right side walls inside the deodorizing box 2, and an S-shaped air duct 42 is formed between the plurality of partitions 41. A packing layer composed of a plurality of packing blocks 43 is arranged in the S-shaped air duct 42. The packing blocks 43 are made of biological packing wrapped with a filter screen. A packing outlet 44 and a packing inlet 45 corresponding to the left and right ends of the packing layer are provided on the front side of the deodorizing box 2, and the packing outlet 44 and the packing inlet 45 are the same size as the packing blocks 43.

[0033] An S-shaped airway is formed between multiple partitions for the waste gas to flow through, which limits the flow direction of the waste gas. At the same time, the S-shaped structure increases the contact time between the waste gas and the filler layer. At the same time, the narrow channel allows the waste gas to fully contact with the biological filler, decomposes and transforms the odor, and improves the utilization rate of the filler.

[0034] It also includes a limiting mechanism, which includes a positioning component 51 arranged at the filler outlet 44 and a pushing component 52 arranged at the filler inlet 45;

[0035] The positioning assembly 51 includes a first sealing plate 511 that is engaged in the packing outlet 44. A sliding plate 512 that is slidably mounted on the partition 41 is fixed on the first sealing plate 511. A stopper 513 is provided on the sliding plate 512. A handle 514 is provided on the first sealing plate 511. Two sliding plates 512 are provided in parallel. The stopper 513 is located on the left side of the sliding plate 512 and serves as a stopper for the packing block. Since the packing block on the left end contacts the exhaust gas first, it contacts the exhaust gas most fully than the packing block on the right side, and its service life is the shortest, and it is replaced more frequently. Since the packing block on the far left is located on the lower sliding plate 512, the packing block is taken out when the sliding plate 512 is pulled out. Similarly, the service life of the packing blocks decreases from left to right.

[0036] The pushing assembly 52 includes a push plate 521 located on the right side of the filling inlet 45 and a connecting plate 523 slidably installed on the right side of the push plate 521. The push plate 521 and the connecting plate 523 are fixed by multiple connecting rods 522. An electric push rod 524 is provided on the outer wall of the deodorizing box 2. The output end of the electric push rod 524 passes through the side wall of the deodorizing box 2 and is fixed to the connecting plate 523.

[0037] When the leftmost filling block is taken out, the electric push rod 524 is started to drive the push plate 521 to move leftward, pushing all the filling blocks to the left. After the push plate 521 is reset, new filling blocks are filled in from the filling inlet 45 to ensure that each filling block can be fully utilized.

[0038] As a preferred technical solution of the utility model: a second sealing plate 53 adapted to the packing inlet 45 is hingedly connected to the outside of the deodorizing box 2, the second sealing plate 53 is engaged with the packing inlet 45, and a sealing sleeve 54 is provided on the outside of the first sealing plate 511 and the second sealing plate 53, and the sealing sleeve 54 is interference-fitted with the packing inlet 45 and the packing outlet 44. The first sealing plate 511 and the second sealing plate 53 cooperate with the sealing sleeve 54 to improve the sealing performance of the deodorizing box 2 and prevent exhaust gas leakage.
