Description

Technical Field

[0001] The invention relates to the field of odor pollution treatment, in particular to a device for deodorizing odorous gas by using biological fillers. Background Art

[0002] As people's quality of life improves, odor pollution has attracted more and more attention, and the number of complaints about odor pollution ranks among the top complaints about various pollution problems. Against this background, deodorization technology has ushered in new developments. Compared with chemical methods, physical adsorption methods and shielding methods, biological deodorization has gradually become the mainstream process for urban odor treatment due to its simple operation, low operating costs and no secondary pollution.

[0003] Common biological deodorization devices are: Figure 1 As shown, the odor is sent from the air inlet into the static pressure air distribution chamber at the bottom of the shell for dispersion, and passes through the biological filler layer arranged on the filler support from bottom to top. The purified gas is discharged from the air outlet at the top of the shell. In order to increase the humidity in the biological filler layer and ensure the activity of microorganisms, a plurality of nozzles are arranged in the shell on the top of the biological filler layer to spray water on the top of the biological filler layer to keep the filler moist.

[0004] Such biological deodorization devices have the following problems: 1. Due to the characteristics of biological deodorization, a sufficient amount of biological filler layers is required. When the odor treatment volume is large, the area of ​​the required biological filler layers also increases accordingly. In order to ensure sufficient treatment effects, more biological filler layers are required, which will inevitably increase the horizontal floor space, thereby limiting its scale of use; 2. The biological filler layers are filled in sequence with fillers of different sizes, with larger fillers filled at the bottom and smaller fillers filled at the top, and they need to be mixed and filled on site, which requires a lot of work. In addition, due to the large area, it is inevitable that people will step directly on the fillers during filling, and it is impossible to ensure that the biological fillers after filling will not short-circuit or break, resulting in excessive local resistance. The airflow distribution is bound to be uneven, resulting in a decrease in the odor treatment effect. Moreover, it is impossible to accurately determine the location of the short circuit or blockage on site and cannot effectively deal with it; 3. Since the nozzle is arranged above the biological filler layer, spraying a sufficient amount of water directly to the top of the biological filler layer can easily wash away the microorganisms attached to the surface of the biological filler layer, resulting in the fact that microorganisms are not suitable for attaching to the upper part of the biological filler layer; but spraying too little water will lead to uneven spraying and local drying, which will affect the growth of microorganisms; 4. When the existing biological deodorization device is in operation, it is impossible to judge the growth of microorganisms in various parts of the entire filler layer. It can only decide whether to stop the machine and dig out the filler for inspection according to the changes in the treatment effect. Moreover, when digging the filler, the filler layer will inevitably be trampled to cause damage and compaction of the filler, forming a compaction, which will affect the subsequent treatment effect, and frequent replacement of fillers will also lead to a rapid increase in operating costs. Summary of the invention

[0005] The purpose of the present invention is to provide a novel biological deodorization device, which can effectively save floor space, easily detect and replace the failed part of the filler, is convenient for maintenance and disposal, and has low operating cost.

[0006] The technical solution of the present invention is: a novel biological deodorization device, comprising a shell body provided with an air inlet and an air outlet, and several layers of biological fillers with different particle sizes, a static pressure air distribution chamber and an air outlet air distribution chamber are respectively provided on both sides of the shell body, the air inlet is arranged on the top of the static pressure air distribution chamber, the air outlet is arranged on the air outlet air distribution chamber, at least two filler frame layers are stacked from bottom to top between the static pressure air distribution chamber and the air outlet air distribution chamber, several filler frames are horizontally arranged in each filler frame layer, the biological fillers are respectively longitudinally filled in the filler frames, and the particle sizes of the biological fillers in each layer of filler frames on the same vertical plane are the same; a temperature and humidity sensor and a spray water pipe with a nozzle are provided in each filler frame.

[0007] A plurality of stacked packing frame layers are arranged between the static pressure air distribution chamber and the air outlet air distribution chamber, a plurality of packing frames are arranged horizontally in each packing frame layer, and longitudinal biological packings are arranged in the packing frames respectively. The particle sizes of the biological packings in each packing frame on the same vertical plane are the same, which is equivalent to using the original horizontally arranged biological packings of different particle sizes vertically. In this way, the odor can enter horizontally from one side of the plurality of stacked packing frames at the same time, and the treated gas is discharged from the other side of the packing frames, which significantly reduces the horizontal footprint of the odor treatment device, and makes full use of the height space to achieve sufficient odor treatment effect, thereby reducing the footprint while ensuring the treatment effect; since a nozzle and a temperature and humidity sensor are separately arranged in each packing frame, the humidity of the biological packing in each packing frame can be effectively guaranteed, and the temperature and humidity in each packing frame can be effectively detected. When the temperature and humidity changes caused by blockage or short flow are found, the single packing frame with the problem can be replaced for rapid processing, and there is no need to replace all the packings at one time, and the biological packings in other frames will not be trampled during the replacement process. The maintenance and disposal are convenient, and the long-term operation cost is lower.

[0008] Along the direction from the static pressure air distribution chamber to the outlet air distribution chamber, the particle size of each biological filler in the filler frame becomes smaller in sequence. The particle size of the biological filler near the static pressure air distribution chamber is larger, which is convenient for odor to enter, and the particle size of the biological filler near the outlet air distribution chamber is smaller, which is convenient for microorganisms to fully attach and ensure the purification and deodorization effect.

[0009] A movable packing loading and unloading port sealing plate is provided on the shell above the packing frame. The packing frames can be filled into the shell through the packing loading and unloading port one by one, and the sealing plate is movably arranged for easy maintenance and disposal.

[0010] The packing frame includes a frame and grids respectively arranged on the frame, the nozzle is arranged at the upper part of the frame, and the temperature and humidity sensor is arranged at the lower part of the frame. The grid can block the leakage of the packing without affecting the diffusion of the gas, and is convenient for pre-loading the vertically arranged packing layers in the packing frame. The nozzle is arranged at the upper part to effectively spray water downward to wet the packing layer, and the temperature and humidity sensor arranged at the bottom can effectively detect the packing state after spraying water, which is conducive to quickly identifying and judging the packing frame with problems.

[0011] The spray water pipe is arranged along the inner edge of the frame, and a pipe interface is arranged on the top surface of the frame. The water pipe is arranged along the edge of the frame, which will not interfere with the filling of the filler, and the pipe interface is convenient for quickly connecting the spray water pipe of the adjacent filling frame and the external water source, which is convenient for modular setting.

[0012] The advantages of the present invention are: small footprint, convenient maintenance and replacement, effective maintenance of biological fillers in various locations in a uniform state, and long service life. BRIEF DESCRIPTION OF THE DRAWINGS
