Description

Technical Field

[0001] The utility model relates to the technical field of deodorizing devices, and more specifically, to a deodorizing device based on a two-stage biological filtration system. Background Art

[0002] There are many kinds of malodorous substances with a wide range of sources. They can cause varying degrees of toxicity to the human respiratory, digestive, cardiovascular, endocrine and nervous systems. Aromatic compounds such as benzene, toluene, styrene, etc. can also cause human deformities and cancer. There are many ways to deal with odor, mainly including physical adsorption, chemical oxidation, biodegradation and absorption. Physical adsorption uses adsorbents to adsorb organic matter in odor; chemical oxidation oxidizes organic matter into harmless substances through chemical reactions; biodegradation uses microorganisms to degrade organic matter into harmless substances; and absorption absorbs harmful gases through solutions. Choosing a suitable process requires considering odor composition, treatment efficiency, cost and environmental requirements.

[0003] Among them, it was found through searching that the utility model patent with patent application number CN202221228229.7 disclosed an odor treatment device, which is mainly composed of an ozone generator, an ozone suction and mixing device, a cleaning and oxidation device, a spray and oxidation device, a pipeline valve and a pressure gauge. A radiator is arranged on the top of the ozone generator, a high-voltage electrical device is arranged at the bottom, and an ozone storage chamber is arranged in the middle; the ozone suction and mixing device is composed of an ejector, a self-priming water pump, a gas-liquid mixer and a pipeline valve; the cleaning and oxidation device and the spray and oxidation device are provided with a defogger plate on the top;

[0004] When this structure is in use, the water inlet of the ejector is connected to the water tank of the cleaning and oxidation device on the right side through a pipe, the outlet of the ejector is connected to the water inlet of the self-priming water pump through a pipe, a valve and a flexible joint, and the outlet of the self-priming water pump is connected to the water tank of the cleaning and oxidation device on the right side through a pipe, a valve and a flexible joint, and a gas-liquid mixer; the air outlet of the cleaning and oxidation device is connected to the air inlet of the spray and oxidation device through a pipe, but this structure is not easy for the gas to fully contact with the filter element when treating odor, resulting in a poor treatment effect and is not convenient enough when used. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a deodorizing device based on a two-stage biological filtration system, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The utility model is implemented in this way. The utility model provides the following technical solutions: a deodorizing device based on a two-stage biological filtration system, comprising a base for support, on which a diversion treatment component is arranged;

[0007] The diversion treatment component includes a treatment chamber arranged on the top of the base, wherein a plurality of microbial treatment filter elements for absorption treatment are stacked in the treatment chamber, and both ends of each microbial treatment filter element are provided with a reflux adapter that is interconnected;

At the same time, when the microbial solution flows in the microbial treatment filter element and the reflux adapter, it will flow back to the secondary treatment chamber through the conduit on the secondary treatment chamber. By increasing the amount of microbial attachment and filling the secondary treatment chamber with carbonaceous biological carriers, the remaining odor components will be decomposed into CO, HO, inorganic salts and clean gas under the action of the microorganisms and discharged into the atmosphere.

[0010] Optionally, in a possible implementation, a spray chamber is provided on one side of the secondary treatment chamber, the spray chamber is connected to the secondary treatment chamber, a pressure gauge is provided on the spray chamber, a main pipe for guiding flow is provided on one side of the pump, the main pipe is connected to the pump, a fan for extracting airflow is provided on one side of the treatment chamber, the fan is detachably connected to the treatment chamber, and a plurality of partition plates for blocking are provided on one side of the treatment chamber away from the secondary treatment chamber and the pump, and the partition plates are arranged side by side;

[0011] It can be seen that in the above technical scheme, by setting up the spray chamber, by spraying on the surface of the carrier, the filter section adopts an intermittent method to spray on the surface of the carbonaceous biological carrier, so as to provide necessary water supply to the microorganisms and flush the decomposition products, and the solution in the main pipe is extracted by the pump, and injected into the treatment chamber through the conduit on the pump, and flows through the microbial treatment filter element and the reflux adapter, and then the fan is started to extract the external odor when the fan is started.

[0012] Technical effects and advantages of the utility model:

[0013] By setting up the diversion treatment component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, a large amount of HS and NH gases in the odor in the treatment room will be dissolved in the solution and degraded by the microorganisms attached to the microbial treatment filter element, thereby reducing the treatment load of the secondary biological stage;

[0014] At the same time, when the microbial solution flows through the microbial treatment filter element and the reflux adapter, it then flows back into the secondary treatment chamber through the conduit on the secondary treatment chamber. By increasing the amount of microbial attachment, the carbonaceous biological carrier is filled in the secondary treatment chamber. Under the action of its microorganisms, the remaining odor components are decomposed into CO, HO, inorganic salts and clean gas and discharged into the atmosphere;

[0015] At the same time, through the setting of the spray chamber, by spraying on the surface of the carrier, the filtration section adopts an intermittent method to spray on the surface of the carbonaceous biological carrier, so as to provide necessary water supply to the microorganisms and flush the decomposition products.

When the fan 13 is started, the external odor is extracted, and the odor enters the treatment chamber 2. The odor in the treatment chamber 2 will cause a large amount of H2S and NH3 gases in the odor to be dissolved in the solution and degraded by the microorganisms attached to the microbial treatment filter element 8, thereby reducing the treatment load of the secondary biological stage, and the specific structure of the component is set as follows;

[0024] The diversion treatment component includes a treatment chamber 2 arranged on the top of the base 1, and a plurality of microbial treatment filter elements 8 for absorption treatment are stacked in the treatment chamber 2, and both ends of each microbial treatment filter element 8 are provided with a reflux adapter 9 that is interconnected;
