Description

Technical Field

[0001] The utility model relates to the field of odor filtering, in particular to a uniform air distribution and deodorization biological filter. Background Art

[0002] The biofilter process is a process that uses the adsorption, absorption and degradation functions of microbial cells to treat odor. Odor enters the biofilter and passes through the wet, porous filter layer full of active microorganisms, using the microbial cells to adsorb, absorb and degrade odor substances to complete adsorption purification.

[0003] The air intake of conventional biofilters is extended to the packing grid plate through a pipe, so that the odor is transported to the bottom of the packing / grid plate. The odor flows on its own in the cavity, and it is impossible to ensure that the odor can be evenly distributed under the packing layer so that it can pass through the packing more evenly. At the same time, when replacing the packing, the internal grid is parallel, so the replacement efficiency is low and the time is long. Utility Model Content

[0004] The utility model aims to provide a uniform air distribution and deodorizing biological filter tank which is easy to clean and has high deodorizing efficiency.

[0005] The purpose of the utility model is achieved as follows: a uniform air distribution deodorization biological filter, including a filter box and an air intake system;

[0006] The filter box is provided with an air outlet layer, a biological filler layer, and an air bin layer in sequence from top to bottom; the air bin layer is evenly divided into multiple groups of independent air bins by a partition wall, and each group of independent air bins is externally connected to an air intake system; the partition wall is extended upward to be provided with a baffle, and the baffle divides the biological filler layer into multiple groups of independent filler bins, and each group of independent filler bins is provided with a discharge port on both side walls and a loading port on the top; the baffle is extended upward to be provided with a partition, and multiple groups of ventilation holes are provided on the partition; a filler grid is provided between the biological filler layer and the air bin layer, and the cross section of the filler grid is set to an inverted V shape; an air outlet is provided on the top of the filter box;

[0007] The air intake system consists of an air intake main pipe, an air intake branch pipe, and an air intake branch pipe. The air intake branch pipes are connected to the air intake branch pipes in sequence. Two groups of air intake branch pipes are extended from the end of each group of air intake branch pipes to communicate with independent air chambers.

[0008] Preferably, the edges of the packing grid are fixed to the warehouse wall and the partition wall by welding, and a support frame is provided at the center of the packing grid and connected to the bottom of the filter box.

[0028] The air intake system 2 is composed of an air intake main pipe 201, an air intake branch pipe 202, and an air intake branch pipe 203.
