[0056] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0057] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] like Figure 1-Figure 2 As shown, the embodiment of the present invention provides a method for deodorizing hollow active silicon supported catalyst, comprising the following steps:

[0059] Step 1: Identify and locate the odor source: Identify and locate the odor source, analyze and record the source, type, concentration and diffusion range of the odor. Specifically, use gas detection equipment to analyze the odor components, analyze the main components and harmful substances of the odor, and determine the specific source of the odor based on the analysis results. The sources of odor include industrial emissions, garbage disposal sites, sewage treatment plants, and farms. Identifying the odor source helps to develop targeted deodorization plans and improve treatment efficiency. At the same time, understanding the odor components helps to select suitable catalysts to ensure catalytic conversion effects;

[0060] Step 2: Odor collection: Use an odor suction fan to extract and collect the odor in the target area. Specifically, use the fan to guide the odor to the catalytic treatment module, and use the odor concentration sensor to monitor the odor concentration in real time. By setting up the fan, the odor can be effectively drawn out from the source to prevent it from continuing to spread;

[0061] Step 3: Gas pretreatment: Configure a pretreatment module to remove impurities in the odor, including particulate matter, impurities, and grease. Before the odor enters the catalytic treatment module, pretreatment is performed to remove impurities that interfere with the catalytic process. Gas pretreatment is achieved through filters and dryers, where the filter is used to capture larger solid particles and grease, and the dryer is used to remove moisture from the gas. Pretreatment can protect the catalyst bed from damage by impurities and extend the service life of the catalyst. At the same time, removing moisture helps prevent catalyst poisoning and improve catalytic efficiency.

[0062] Step 4: Temperature and humidity control: Regulate the temperature and humidity of the odor so that the temperature and humidity of the odor meet the optimal temperature and humidity of the catalytic reaction. Specifically, install a temperature sensor and a humidity sensor in the odor delivery pipeline to monitor the temperature and humidity of the odor in real time. According to the data of the temperature sensor and the humidity sensor, adjust the heating or cooling device so that the temperature of the odor reaches the optimal range of the catalytic reaction. The optimal temperature of the odor to meet the catalytic reaction is 25-35°C, and the optimal humidity of the odor to meet the catalytic reaction is 45-65%. The operating state of the dehumidification device is adjusted by the controller to keep the humidity of the odor within a suitable range. The suitable temperature and humidity help to improve the activity and stability of the catalyst and ensure the efficient progress of the catalytic conversion process.

[0063] Step 5: Catalytic conversion and adsorption to treat odor in coordination: The odor enters the contact chamber and is adsorbed in the porous structure of the hollow active silicon. At the same time, the catalyst loaded on the hollow active silicon catalyzes the odor to undergo a chemical reaction. After the odor enters the contact chamber, the odor molecules are adsorbed by the porous structure of the hollow active silicon. The porous structure of the hollow active silicon is used to increase the contact area and contact time between the odor and the catalyst. The catalyst loaded on the hollow active silicon catalyzes the chemical reaction of the odor molecules to convert the odor into harmless or low-toxic substances.

[0064] The adsorption of hollow active silica is mainly based on physical adsorption and chemical adsorption:

[0065] Physical adsorption is due to the intermolecular forces on the active silicon surface, which adsorbs odor molecules on its surface and pores;

[0066] Chemical adsorption is due to the chemical reaction between the functional groups on the surface of active silicon and the odor molecules, fixing them on the active silicon;

[0070] As a catalyst carrier: hollow active silicon can be used as a catalyst carrier, which can improve the efficiency and effect of deodorization after loading the catalyst;

[0071] The method for loading a catalyst on hollow active silicon comprises:

[0072] Impregnation method: soak the hollow active silicon in a solution containing a catalyst precursor, so that the catalyst precursor is adsorbed on the active silicon, and then the precursor is converted into a catalyst through drying, calcination and other treatments;

[0073] Co-precipitation method: hollow active silicon and catalyst precursor are added to the precipitant solution at the same time, so that the catalyst precursor is precipitated on the surface and pores of the active silicon, and then the hollow active silicon loaded with catalyst is obtained through drying, calcination and other treatments;

[0074] Sol-gel method: The catalyst precursor is dissolved in a solvent to form a sol, and then the hollow active silicon is added to the sol to gel the sol on the surface and pores of the active silicon. After drying, calcination and other treatments, the hollow active silicon loaded with the catalyst is obtained.

[0075] Step 6: Gas purification: Purify the odor after catalytic conversion and adsorption treatment again to remove residual harmful substances. Specifically, use a washing tower to remove harmful substances remaining in the gas after catalytic conversion, and install online detection equipment at the discharge port of the washing tower to monitor the concentration and composition of the exhaust gas in real time.

[0076] In one embodiment, when the odor enters the contact chamber, an adaptive control algorithm is used to calculate the residence time of the odor based on the composition of the odor and the activity of the catalyst;

[0077] The adaptive control algorithm consists of the following steps:

[0078] Odor detection: Obtain odor composition data in real time through gas detection sensors, including VOCs, sulfides, and nitrogen oxides;

[0079] Catalyst detection: Use gas chromatography online analyzer to detect the activity of the catalyst in real time. Factors affecting the activity of the catalyst include time, temperature, and humidity;

[0080] Data processing: normalize the odor component data and smooth the catalyst activity data;

[0081] Construct residence time calculation model: Based on the principle of mass conservation, establish the residence time model of odor molecules in the contact chamber;

[0082] The residence time T is expressed as:

[0083] Wherein, V is the volume of the contact chamber, Q is the gas flow rate, and the gas flow rate is proportional to the fan speed;

[0084] Set the residence time threshold: Set the residence time threshold T_thresho ld according to the activity of the catalyst and the degree of harm of the odor components;

[0085] Set wind speed adjustment rules: Compare the calculated residence time T with T_threshold, increase or decrease the fan speed according to the comparison result, adjust the residence time of the odor, and when adjusting the wind speed, consider the impact of wind speed changes on system stability and energy consumption, and adopt a gradual adjustment strategy;

[0086] Real-time feedback and iterative optimization: The odor components after treatment are monitored in real time through gas detection sensors, and the feedback results are used to evaluate the algorithm performance. According to the feedback results, the algorithm parameters are iteratively optimized.

[0088] The fan, pretreatment module, temperature and humidity control module, contact chamber and washing tower are connected in sequence through pipelines. The gas detection equipment is installed in the pipeline between the fan and the pretreatment module, and the catalytic treatment module is installed inside the contact chamber.

[0089] In one embodiment, a fan is used to direct the odor into the system;

[0090] The pretreatment module is used to remove impurities in the odor, including solid particles, moisture, and grease. The gas pretreatment module includes a filter and a dryer. The filter is used to capture larger solid particles and grease, and the dryer is used to remove moisture from the gas.

[0091] The catalytic treatment module is hollow active silicon used to absorb odor molecules and catalyze chemical reactions of odor;

[0092] The contact chamber is used to load the hollow active silicon, and an air flow diffusion plate or a nozzle is arranged inside the contact chamber.

[0093] When the hollow active silicon loaded catalyst deodorization system is working: the odor is introduced into the system through the fan, the composition of the odor is analyzed by the gas detection equipment, the main components and harmful substances of the odor are analyzed, and the specific source of the odor is determined according to the analysis results. Then, the solid particles, moisture, grease and other impurities are removed by the pretreatment module, and the temperature and humidity of the odor are adjusted to the optimal range by the temperature and humidity control module. Then the odor enters the contact chamber, and the catalytic treatment module inside it adsorbs the odor molecules and catalyzes the chemical reaction of the odor, converting the odor into harmless or low-toxic substances. The treated odor enters the washing tower, and the odor is purified again by the washing tower and discharged after purification.
