[0002] Malodorous waste gas not only easily affects the ecological environment, but also has great harm to human health, causing central nervous system disorders and pathological changes, leading to chronic and acute diseases. Therefore, the effective removal of malodorous gases is of great significance to protecting the ecological environment and safeguarding people's lives and health.

[0003] For the treatment of malodorous waste gas, compared with absorption method, adsorption method, catalytic combustion method, etc., biological method has the advantages of low investment, high removal efficiency, low energy consumption, no secondary pollution, etc. and has broad application prospects. Biological methods include biological filtration, biological washing and biological trickling filtration. Among them, the biological trickling filtration method is suitable for removing low-concentration and large-volume malodorous waste gas due to its simple operation process, high deodorization efficiency and large buffering capacity. Therefore, it has become one of the important development directions of biological deodorization method. Its deodorization principle is mainly to use the biological oxidation and decomposition of microorganisms to convert pollutants into harmless substances. Malodorous waste gas is transmitted through the air-water interface and attached to the biofilm on the surface of inorganic filler. The microorganisms in the membrane use the pollutants in the gas as nutrients required for their growth and reproduction, and finally oxidize and decompose large molecules or complex organic molecules into simple CO2, H2O, NO3 through alienation. - and SO4 2- And other inorganic substances to achieve the purpose of purification.

[0004] Waste disposal, feed processing, fermentation and pharmaceutical production often produce foul-smelling gases containing hydrogen sulfide, ammonia, mercaptans, sulfides, etc., and such waste gases usually carry large solid particles (such as smoke, dust, fibers, etc.), which will be deposited in pipes and biological filler beds, easily causing blockages, and other microorganisms attached to them can easily destroy the ecological balance of the filter bed; after a long period of waste gas treatment, the biological filler bed is prone to blockage due to excessive growth of microorganisms and accumulation of their metabolites. These blockages can easily affect the purification effect of the malodorous waste gas in the device and even bring safety hazards.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention, so that people familiar with the technology can understand the advantages of the present invention.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0029] Example 1

[0030] See also Figures 1 to 3 In an embodiment of the present invention, an integrated multi-stage anti-clogging biological deodorization and purification device includes a box body 1, wherein the interior of the box body is divided into a pretreatment chamber 2, a biological deodorization chamber 3 and a post-treatment chamber 4 which are connected in sequence from left to right by setting a partition.

[0031] In this embodiment, the left and right sides of the housing 1 are fixedly provided with an air inlet 11 and an exhaust port 12, respectively. A water spray pipe 13 is provided at the top, and a sewage drain pipe 14 is provided at the bottom. Specifically, the air inlet 11 is located near the bottom of the outer wall of the pretreatment chamber 2. The exhaust port 12 is located near the top of the outer wall of the post-treatment chamber 4.

[0032] In this embodiment, a partition is fixed inside the pretreatment chamber 2, which divides the pretreatment chamber into a dust removal and humidification chamber and a heating chamber, both of which are connected by an opening at the upper end. A corrugated plate 21 is fixed inside the pretreatment chamber 2. A plurality of spray nozzles 22 connected to the spray water pipe 13 are provided above the corrugated plate 21. The water mist sprayed from the spray nozzles 22 wets the corrugated plate 21 provided below and forms a water flow on its surface. Exhaust gas containing larger solid particles entering the device through the air inlet pipe first passes through the corrugated plate 21 with a larger specific surface area. Due to the special corrugated shape of the corrugated plate 21, the flow direction of the exhaust gas inside the device is constantly changing. The solid particles therein are easily impacted on the plate surface due to inertia, and are thereby swept by the water flow from top to bottom and washed to the bottom of the pretreatment chamber 2. The wastewater mixed with solid particles is discharged through the drain pipe 14. The exhaust gas after dust removal and humidification passes through the heating air guide 23, which is provided with an electric heating pipe 231 and a guide plate 232. The guide plate 232 is located on both sides of the electric heating pipe 231 (such as Figure 2(as shown), the exhaust gas passing through the device can be heated. Humidification and heating of the exhaust gas increases its humidity and temperature, thereby promoting the reactivity of microorganisms to the exhaust gas. At the same time, it ensures that the temperature and humidity of the incoming exhaust gas do not affect the activity of microorganisms within the device even in extreme weather conditions.

[0033] In this embodiment, the first spray nozzle 22 is connected to the water inlet 13 .

[0034] In this embodiment, a partition is fixed inside the biological deodorization chamber 3. The partition divides the pretreatment chamber into a left treatment chamber and a right treatment chamber with an opening at the top. Both the left and right treatment chambers are provided with a biological filler layer 32, and a second spray nozzle 33 is provided above the biological filler layer 32. A communication port is provided on the lower side of the partition between the left biological deodorization chamber and the heating chamber of the biological deodorization chamber 3, and a communication port is provided on the lower side of the partition between the post-treatment chamber 4 and the right biological deodorization chamber of the biological deodorization chamber 3. This design allows the pretreated exhaust gas to enter the left and right biological treatment chambers for exhaust gas treatment through the communication port connected to the pretreatment chamber. An air distribution plate 31 is provided in the left treatment chamber, and the air distribution plate 31 is located below the biological filler layer 32. Pressure sensors 36 are provided in both the left and right treatment chambers. A backwash spray pipe 34 is provided below the biological filler layer 32, and a backwash nozzle 35 is provided on the backwash spray pipe 34. A demister 41 is provided inside each of the post-processing chambers 4 .

[0035] Example 2

[0036] In this embodiment, the device in Example 1 is used for treatment. After being treated in the pretreatment chamber 2, the solid particulate matter contained in the exhaust gas is removed. Subsequently, the exhaust gas flows into the left and right treatment chambers in the biological deodorization chamber 3 through the connecting port provided between the pretreatment chamber 2 and the biological deodorization chamber 3 for deodorization treatment. The air distribution plate 31 provided above the connecting port through which the exhaust gas first passes in the biological deodorization chamber 3 ensures that the incoming exhaust gas is evenly dispersed when passing through the biological packing layer 32, thereby preventing the problem of excessive treatment differences between the packing components in each part, thereby ensuring that the exhaust gas can be efficiently oxidized and decomposed by microorganisms on the packing bed. Each layer of biological packing bed 32 is equipped with a backwash water pipe 34 and a backwash nozzle 35. Simultaneously, pressure sensors 36 in the left and right chambers of the biological deodorization chamber 3 monitor the real-time pressure within the chamber during waste gas treatment. If the pressure within the chamber exceeds the set pressure value due to clogging of the biological packing bed 32, the control system activates the backwash device to flush the biological packing bed 32 until the pressure within the chamber returns to normal, allowing the waste gas to be effectively treated and discharged smoothly within the biological treatment chamber 3. This real-time pressure monitoring and backwashing process can solve the problem of clogging of the biological packing bed 32 due to prolonged use, which can affect the deodorization effect and threaten the safety of the device.

[0037] The gas treated in the biological treatment chamber 3 flows into the post-treatment chamber 4 through the connecting port provided between the biological treatment chamber 3 and the post-treatment chamber 4, and the mist eliminator 41 provided therein removes the water vapor entrained in the gas, and finally the clean gas is discharged through the exhaust port 12, completing the deodorization treatment of the entire waste gas.
