Abstract
Description
Technical Field
[0001] The present invention relates to a deodorization method, in particular to a method for high-efficiency catalytic composite nano-capture deep deodorization of waste gas with complex components, which is applied in the field of waste gas purification with complex components. Background Art
[0002] Adsorption concentration + combustion is often used in combination. It is suitable for waste gas with high calorific value of organic components, but not for waste gas containing or producing highly corrosive components. Combustion has very high requirements for reaction conditions and will produce highly toxic dioxin secondary pollutants. The combustion method usually requires the addition of a certain amount of natural gas to assist combustion during operation, which greatly increases the energy consumption of the treatment.
[0003] Activated carbon is a commonly used material for adsorption. It is used as a terminal compliance guarantee facility for combined processes under conditions of large air volume and low concentration of exhaust gas. However, its adsorption efficiency is low, and the frequency of replacement and regeneration is high. After adsorption saturation, it is often treated as hazardous waste and requires professional treatment by qualified units.
[0004] Biological deodorization technology uses microorganisms in the liquid phase to consume components in the waste gas. The equipment is relatively simple and there is almost no secondary pollution. However, the cultivation of the bacteria requires a period of time and requires a relatively stable operating load.
[0005] The absorption method is to remove the water-soluble components in the waste gas by reacting with the absorbent, or dissolving them in the absorbent, but the absorbent is selective for the waste gas components and requires high absorption efficiency. The absorbed liquid often needs to be reprocessed.
[0006] The above methods for treating malodorous gases all have problems such as high equipment investment, high operating cost, large space occupation and possible secondary pollution to varying degrees. These problems make these methods unable to treat malodorous gases efficiently, thereby reducing their practical application effects. Summary of the invention
[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to achieve efficient treatment of malodorous gases through low cost, small space occupation and low secondary pollution, so as to improve the effect of practical application.
[0008] In order to solve the above problems, the present invention provides a method for high-efficiency catalytic composite nano-capture deep deodorization of waste gas with complex components, comprising a deodorization tower, a material collection box matched with the deodorization tower is fixedly installed at the lower end of the deodorization tower, a deodorization controller located on the right side of the deodorization tower is fixedly connected to the upper end of the material collection box, and an intelligent deodorization control system is installed in the deodorization controller; A catalytic enrichment coupling reactor is installed on the upper side of the deodorizing tower, and a plurality of atomizing nozzles are installed on the lower side of the outer end of the deodorizing tower, and the inner end of the atomizing nozzle extends into the deodorizing tower. The specific steps include: S1. Pre-treating the air intake, and delivering the pre-treated malodorous gas to the deodorizing tower through the air inlet provided at the upper end of the deodorizing tower; S2. Catalytic enrichment: the malodorous gas entering the deodorization tower moves from top to bottom, and the catalytic enrichment coupling reactor performs deep VOCs elimination on the malodorous gas; The catalytic enrichment coupling reactor can produce enrichment and catalytic coupling effects to treat and transform the difficult-to-absorb molecules or small molecules in the malodorous gas; S3. Nano-liquid capture. When the deodorizing tower is started, the intelligent deodorizing control system controls the atomizing nozzle to spray the nano-liquid atomized on the lower side of the deodorizing tower; The gas after deep VOCs elimination in the catalytic enrichment coupling reactor enters the lower side of the deodorization tower, where the atomized nano-liquid adsorbs the VOCs and odor molecules in the gas and generates non-toxic and harmless stable compounds, which fall into the collection box. Nanofluids can adsorb easily absorbable molecules or macromolecules in malodorous gases; S4. Detection: The gas captured by the nanofluid is discharged through the gas outlet located at the lower left end of the deodorization tower for detection. The intelligent deodorization control system detects and determines the composition of the gas through a gas detector; S5. Cycle. When the intelligent deodorization control system determines that the detection gas treatment is unqualified, the gas is controlled by the electric control valve on the pipeline to re-enter the deodorization tower from the air inlet for re-circulation treatment. When the number of cycles is greater than 3 times, the intelligent deodorization control system sends warning data to the aggregate box; S6. Capture enhancement: when the detected gas needs to be recirculated, the intelligent deodorization control system determines that the original capture intensity needs to be enhanced, and then intelligently adjusts the atomizing nozzle to increase the nano-liquid spray volume and spray range; S7. Exhaust: When the intelligent deodorization control system determines that the detected gas is qualified, the gas is discharged and released through the electric control valve on the pipeline; Based on the intelligent control of the intelligent deodorization control system, the catalytic enrichment coupling reactor and the nano-liquid are organically coordinated. For the components of the difficult-to-absorb molecules or small molecules in the malodorous gas, the catalytic enrichment coupling reactor is used to enrich and degrade them for deodorization or convert them into molecules that are easy to absorb and capture. Then, the nano-liquid is used to absorb and capture the remaining easily absorbable molecules or large molecular components in the malodorous gas, completing the treatment of the malodorous gas and achieving the goal of no perception by the human body. At the same time, the consumption of nano-liquid and other catalytic raw materials is minimized, reducing the deodorization cost, and the intelligent deodorization control system is used to optimize the number of deodorization cycles.
[0009] The above-mentioned method of high-efficiency catalytic composite nano-capture deep deodorization for waste gas with complex components has the advantages of high safety, low operating cost, small space occupation and low secondary pollution, which effectively improves the actual application effect of malodorous gas treatment.

DETAILED DESCRIPTION
[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0020] The first implementation method: Figure 1 - Fig.12 The invention shows a method for high-efficiency catalytic composite nano-capture deep deodorization of waste gas with complex components, which includes a deodorization tower 1, a material collecting box 14 matched with the deodorization tower 1 is fixedly installed at the lower end of the deodorization tower 1, and a deodorization controller 11 located on the right side of the deodorization tower 1 is fixedly connected to the upper end of the material collecting box 14, and an intelligent deodorization control system is installed in the deodorization controller 11; A catalytic enrichment coupling reactor 2 is installed on the upper side of the deodorizing tower 1, and a plurality of atomizing nozzles 3 are installed on the lower side of the outer end of the deodorizing tower 1, and the inner end of the atomizing nozzle 3 extends into the deodorizing tower 1. The specific steps include: S1. Pre-treating the air intake, the pre-treated malodorous gas is transported to the deodorizing tower 1 through the air inlet 12 disposed at the upper end of the deodorizing tower 1. The pre-treatment can be set according to the properties of the malodorous gas, such as dehumidification, cooling and other means; S2. Catalytic enrichment, the malodorous gas entering the deodorization tower 1 moves from top to bottom, and the catalytic enrichment coupled reactor 2 performs deep VOCs elimination on the malodorous gas; The catalytic enrichment coupling reactor 2 can produce enrichment and catalytic coupling effects to process and transform the difficult-to-absorb molecules or small molecules in the malodorous gas; S3. Nano-liquid capture. When the deodorizing tower 1 is started, the intelligent deodorizing control system controls the atomizing nozzle 3 to spray the nano-liquid into atomized form on the lower side of the deodorizing tower 1; The gas after deep VOCs elimination in the catalytic enrichment coupling reactor 2 enters the lower side of the deodorization tower 1, and the atomized nano-liquid adsorbs the VOCs and odor molecules in the gas to generate non-toxic and harmless stable compounds, which fall into the collection box 14; Nanofluids can adsorb easily absorbable molecules or macromolecules in malodorous gases; S4 detection, the gas captured by the nano-liquid is discharged through the outlet 13 located at the lower left end of the deodorization tower 1 for detection, and the intelligent deodorization control system detects and determines the composition of the gas through a gas detector; S5. Cycle, when the intelligent deodorization control system determines that the detection gas treatment is unqualified, the gas is controlled by the electric control valve on the pipeline to re-enter the deodorization tower 1 from the air inlet 12 for re-circulation treatment, and after the limited number of cycles is greater than 3 times, the intelligent deodorization control system sends warning data to the aggregate box 14, and promptly checks the catalytic enrichment coupling reactor 2 in the deodorization tower 1, and checks the atomizing nozzle 3 and the nano-liquid to ensure the effectiveness of their effects; S6. Capture enhancement. When the detection gas needs to be recirculated, the intelligent deodorization control system determines that the original capture intensity needs to be enhanced, and then the atomizing nozzle 3 is intelligently controlled to increase the nano-liquid spray volume and spray range; S7. Exhaust: When the intelligent deodorization control system determines that the detected gas is qualified, the gas is discharged and released through the electric control valve on the pipeline; Based on the intelligent control of the intelligent deodorization control system, the catalytic enrichment coupling reactor 2 and the nano-liquid are organically coordinated. For the components of the difficult-to-absorb molecules or small molecules in the malodorous gas, the catalytic enrichment coupling reactor 2 is used to enrich, degrade and deodorize or convert them into molecules that are easy to absorb and capture, and then the nano-liquid is used to absorb and capture the remaining easily absorbable molecules or large molecular components in the malodorous gas, so as to complete the treatment of the malodorous gas and achieve the effect of human body insensitivity; at the same time, the consumption of nano-liquid and other catalytic raw materials (including the catalyst and adsorption material used in the catalytic enrichment coupling reactor 2) is minimized, the deodorization cost is reduced, and the intelligent deodorization control system is used to optimize the number of deodorization cycles. The main power of the deodorization tower 1 for the deodorization treatment of the malodorous gas can be set at the air inlet 12 end, and the air can be blown downward, or it can be set at the air outlet 13 end, through The treatment is carried out by exhausting air, which is a prior art and will not be elaborated on here. Through the synergistic effect of the catalytic enrichment coupling reactor 2, the atomizing nozzle 3, the nanofluid and the intelligent deodorization control system, the VOCs and odor molecules in the malodorous gas can be removed efficiently and quickly. The entire deodorization process is carried out at room temperature, which significantly reduces the investment and operating costs of malodorous gas treatment. The deodorization method has the advantages of high safety, low operating cost, small space occupation and low secondary pollution, which effectively improves the actual application effect of malodorous gas treatment. In addition, through the detection and evaluation of the treated gas, the safety of the exhaust gas can be ensured, and the application effect and quality of the catalytic enrichment coupling reactor 2 and the nanofluid can be monitored and adjusted in real time, thereby enhancing the intelligence level of the malodorous gas treatment process, promoting the dual improvement of treatment efficiency and quality, and further improving the economic benefits.
[0021] Figure 1 - Figure 3 It is shown that the storage tank is filled with nano liquid, the core component of the nano liquid contains multiple conjugated double bond systems, the conjugated double bond system mainly refers to the metal organic framework MOFs, which is a type of porous material formed by self-assembly of metal ions or metal clusters and organic ligands through coordination bonds. The atomized nano droplets have huge surface energy and a strong ability to provide electron pairs, which further enhances the reactivity of absorbing VOCs and odor molecules, making it easy to react chemically at room temperature to generate non-toxic and harmless stable compounds, thereby achieving the purpose of completely removing waste gas molecules. The atomizing nozzle 3 can atomize the nano liquid into small droplets with a diameter of 0.1 to 10 μm, so that the specific surface area of the small droplets is greatly increased, and the ability to adsorb and absorb VOCs and odor molecules is significantly improved. It can be effectively seen from the following absorption liquid and nano liquid performance test comparison table that the effect of using nano liquid to adsorb and deodorize odorous gas is significantly better than that of the absorption liquid, and then the nano liquid can efficiently remove VOCs and odor molecules in the odorous gas, and achieve the absorption and treatment effect of easily absorbable molecules or macromolecules in the odorous gas.
[0022] Table 1: Comparison of performance tests of absorption liquid and nano liquid:
[0023] Figure 1 - Figure 3 It is shown that the catalytic enrichment coupling reactor 2 realizes the rapid step-by-step reduction of organic matter through the multi-stage series connection of nanocatalysis and enrichment materials, forming a step-by-step reduction-series enrichment regeneration nanocatalysis coupling effect, wherein the nanocatalysis is to select nano-scale multi-element manganese oxide particles to form an entropy-controlled nanocatalyst, and the enrichment material can be a porous nanoreactor or a molecular sieve. The catalytic enrichment coupling reactor 2 uses the entropy-controlled nanocatalyst to catalyze the generation of O free radicals. The entropy-controlled nanocatalyst selects multi-element manganese oxide, which has transient strong oxidizing properties. Therefore, adsorbing and anchoring it to the surface of the enrichment material will greatly increase the life of the free radicals and thus improve the oxidation efficiency. Through the multi-stage series connection of nanocatalysis and enrichment materials, the rapid step-by-step reduction of organic matter can be achieved. The deep VOCs elimination technology of the step-by-step reduction-series enrichment regeneration nanocatalysis coupling effect cooperates with the nanocatalysis and deep enrichment process to achieve deep removal of odorous gases. The following catalytic enrichment coupling reactor adsorption test performance table shows that the catalytic enrichment coupling reactor 2 can effectively adsorb VOCs and effectively treat the difficult-to-absorb molecules or small molecules in the odorous gas.
[0024] Table 2: Catalytic enrichment coupled reactor adsorption test performance table
[0025] For complex odors, based on intelligent control, the catalytic enrichment coupling reactor 2 and the nano-liquid capture are organically coordinated, and the difficult-to-absorb or small-molecule odor components in the complex odor are enriched, degraded and deodorized in the catalytic enrichment coupling reactor 2 or converted into molecules that are easy to absorb and capture, and then the remaining odor molecules (easy to absorb or large molecules) are absorbed and captured by the atomized nano-liquid to achieve no perceived odor; the intelligent control system is used to achieve automatic intelligent matching of the operating process parameters of the catalytic enrichment coupling reactor 2 and the nano-liquid, so as to deodorize the complex odor with high efficiency and low consumption, so as to achieve complete insensitivity to human sense of smell and meet the emission standards.
[0026] Second implementation method: Figure 1 - Fig.12The invention shows a method for high-efficiency catalytic composite nano-capture deep deodorization of waste gas with complex components. A plurality of arc-shaped sealing plates 5 evenly distributed along the circumferential direction of the deodorization tower 1 are fixedly installed on the right end of the outer end of the deodorization tower 1, and the plurality of arc-shaped sealing plates 5 are all located below the catalytic enrichment coupling reactor 2. A nozzle fixing arc block 51 is fixedly connected to the inner end of the arc-shaped sealing plate 5. A plurality of active cylinders 4 evenly distributed along the vertical direction are embedded in the arc-shaped sealing plate 5. An atomizing nozzle 3 is arranged in the active cylinder 4. A plurality of steering control components 6 are fixedly connected to the outer end of the atomizing nozzle 3, and the other end of the steering control component 6 is fixedly connected to the active cylinder 4. The intelligent deodorization control system includes an intelligent deodorization processing unit, the input end of which is connected to a deodorization parameter setting unit, an emission quality detection unit and an instruction receiving unit, and the output end of which is connected to an exhaust control unit, an intake control unit, a spray control unit, a steering control unit and a data output unit; The input ends of the deodorization parameter setting unit and the instruction receiving unit are both connected to the data port signal provided on the deodorization controller 11, and the input end of the emission quality detection unit is connected to the gas detector signal provided on the left pipe of the gas outlet 13; The output end of the exhaust control unit is connected to the signal of the electric control valve arranged on the left side pipeline of the air outlet 13, the output end of the air intake control unit is connected to the signal of the air intake valve arranged on the upper end pipeline of the air intake 12, the output end of the spray control unit is connected to the nano liquid delivery structure arranged at the rear of the deodorizing tower 1, and the nano liquid delivery structure is connected and coordinated with the atomizing nozzle 3, the output end of the steering control unit is connected to the steering control unit 6 signal, and the output end of the data output unit is connected to the data port signal arranged on the deodorizing controller 11. Through the cooperation of the atomizing nozzle 3, the active cylinder 4 and the steering control unit, the range and intensity of the nano liquid spray can be doubly strengthened when the gas does not meet the standard after a single deodorization. The regulating effect increases the number of small droplets of nano-liquid spray, promotes its contact reaction with VOCs and odor molecules, fully improves the treatment effect and quality of odorous gases, and then can realize the actual state of odorous gases, realize its rapid and effective deodorization effect, and promote the intelligent regulation of the deodorization process, so as to be suitable for odorous gases of different concentrations and improve its application range. In addition, through the cooperation of the exhaust control unit and the intake control unit, while ensuring the intake and exhaust of the odorous gases in the normal treatment process, it can also perform intermittent emission regulation according to the actual concentration of the odorous gases, so as to ensure the circulation treatment effect of high-concentration odorous gases and ensure the compliance and safety of emissions.
[0027] Fig. 9 - Fig.12The outer end of the active cylinder 4 is fixedly connected to an elastic bottom plate 41, the inner end of the active cylinder 4 is fixedly connected to an elastic cone head 42, the atomizing nozzle 3 penetrates the elastic bottom plate 41 and the elastic cone head 42, and is fixedly connected to the elastic bottom plate 41 and the elastic cone head 42. The arrangement of the elastic bottom plate 41 and the elastic cone head 42 can effectively ensure the flexibility of the atomizing nozzle 3, so that the atomizing nozzle 3 can fully turn under the drive of the steering adjustment control unit 6, promote the diffusion range of the nano liquid spray, enhance its adsorption reaction to VOCs and malodorous gases, improve the efficiency and quality of malodorous gas treatment, reduce the number of cycles in the deodorization process, and effectively achieve the purpose of reducing energy consumption and reducing deodorization costs.
[0028] Fig. 9 - Fig.10 A control chamber 61 is provided in the steering control unit 6, and both inner walls of the control chamber 61 perpendicular to the circumferential direction of the deodorizing tower 1 are fixedly connected with control electric heating plates 62, and a spiral temperature-sensitive deformation strip 63 is fixedly connected between the two control electric heating plates 62. The output end of the steering control unit is connected with the control electric heating plate 62 signal. Through the cooperation of the control electric heating plate 62 and the steering control unit, the flexibility of the working range of the atomizing nozzle 3 can be promoted, the spray range of the atomizing nozzle 3 can be expanded, and the filling of the space in the deodorizing tower 1 can be achieved, thereby promoting the adsorption reaction effect on VOCs and odorous gases, ensuring the deodorization quality, and promoting the compliance and safety of emissions.
[0029] In the process of deodorizing malodorous gases by the catalytic enrichment coupling reactor 2 and the nano-liquid, carbon dioxide, water or stable compounds will be produced, and no new secondary pollutants such as nitrogen oxides, dioxins or phosgene will be produced; a small amount of waste liquid, such as nano-saturated liquid, will also be produced, and the waste liquid can be treated by conventional biochemical technology; there will also be a small amount of solid waste, such as catalytic materials and activated carbon, which can be recycled by manufacturers or Green Island, so the whole deodorization process has good environmental protection.
[0030] Figure 1 - Fig.12 The nano liquid delivery structure is shown to include a storage tank arranged at the rear of the deodorizing tower 1, a delivery pump connected to the storage tank is arranged at the front end of the storage tank, a pipeline diverter is fixedly connected to the output end of the delivery pump, the pipeline diverter is fixedly connected to the atomizing nozzle 3 through a connecting hose, and the output end of the spray control unit is connected to the delivery pump signal.
[0031] Figure 1 - Fig.12It is shown that in the process of treating malodorous gas, the technician first inputs relevant parameters about deodorization control into the deodorization parameter setting unit through the data port of the aggregate box 14. These parameters include but are not limited to parameter data such as deodorization standard, spray power, air intake rate and steering range. The intelligent deodorization processing unit can process and analyze these data, and then control the subsequent deodorization process. After the parameter setting is completed, the technician transmits the deodorization start instruction to the instruction receiving unit through the data port of the aggregate box 14. After the intelligent deodorization processing unit receives the start instruction transmitted by the instruction receiving unit, the copper drum spray control unit starts the delivery pump so that the atomizing nozzle 3 can spray small droplets of nano-liquid atomization, and then controls the air intake control unit to open the air intake valve, so that the pre-treated malodorous gas enters the deodorization tower 1 through the air inlet 12 and moves from top to bottom, so that the malodorous gas first passes through the nano-catalysis and deep enrichment of the catalytic enrichment coupling reactor 2 to eliminate the VOCs in the malodorous gas, and then the gas enters the spray space of the atomizing nozzle 3, and the nano-liquid spray small droplets are used to spray small droplets of the gas. VOCs and odor molecules undergo an adsorption reaction to eliminate VOCs and odor molecules in the malodorous gas. The treated gas enters the gas outlet 13, and is subjected to component analysis and detection by a gas monitor arranged on the left side thereof. Then, the emission quality detection unit transmits the quality data of the deodorized gas to the intelligent deodorization processing unit. The intelligent deodorization processing unit judges and compares the quality data. After judging that the deodorized gas meets the emission standard, the emission control unit controls the electric control valve located on the left side of the gas outlet 13 to open the emission pipe, and discharges the qualified gas. After judging that the deodorized gas does not meet the emission standard, the emission control unit controls the electric control valve located on the left side of the gas outlet 13 to open the circulation pipe, and the unqualified gas re-enters the deodorization tower 1 through the catalytic enrichment coupling reactor 2 for re-circulation treatment. At the same time, the intelligent deodorization processing unit also controls the air intake valve to be closed through the air intake control unit, so that the external malodorous gas can no longer enter the deodorization tower 1 at this time, thereby ensuring the treatment quality of the circulation treatment process and the accuracy of data acquisition, which is convenient for the effectiveness of subsequent intelligent regulation.
[0032] When the intelligent deodorization treatment unit controls the circulation treatment of unqualified gases through the coordinated action of the emission control unit and the air intake control unit, the emission quality detection unit and the gas analysis detector of the intelligent deodorization treatment unit cooperate to continuously monitor the gas composition data, and count the number of cycles until the emission reaches the standard. When the number of cycles reaching the standard does not exceed 3 times, after the exhaust control unit controls the electric control valve to open the distribution pipeline to discharge the qualified gas, the intelligent deodorization treatment unit will also issue control instructions to the spray control unit and the steering control unit, control the delivery pump through the spray control unit to increase the spray volume, and control the two steering control units set at diagonal positions through the steering control unit. The regulating electric heating plate 62 in the control unit 6 is powered on and heated, so that the spiral temperature-sensitive deformation strip 63 connected thereto can produce heat-induced contraction deformation, and then the diagonal spiral temperature-sensitive deformation strip 63 can drive the steering control unit 6 to produce contraction deformation, and produce stretching traction on the other pair of diagonal steering control units 6, so that they produce elastic elongation, and promote the atomizing nozzle 3 to produce a forward tilting action in the active cylinder 4; then the steering control unit cuts off the power supply of the regulating electric heating plate 62 in the above diagonal position so that it is no longer heated, and then the regulating electric heating plates 62 in the other pair of diagonal steering control units 6 are powered on and heated, so that the spiral temperature-sensitive deformation strip 63 connected thereto can produce The heat-induced shrinkage deformation can drive the diagonal spiral temperature-sensitive deformation strip 63 to shrink and deform the steering control unit 6. The electric heating plate 62 at the diagonal position is powered off and no longer generates heat. The flow of spray and malodorous gas causes the spiral temperature-sensitive deformation strip 63 to cool down quickly, resulting in recovery deformation. The other pair of steering control units 6 are stretched under the shrinkage deformation, causing the atomizing nozzle 3 to tilt in the active tube 4. Such repeated cycle control can effectively expand the spray range of the atomizing nozzle 3, promote the full contact between the nano-liquid spray droplets and the VOCs and odor molecules in the gas, and improve the adsorption reaction. efficiency and effect; and, in the process of initially treating the malodorous gas of this concentration, the intelligent deodorization treatment unit can first independently control the spray control unit and the steering control unit to determine the effect of changing their power parameters and steering range to treat the malodorous gas, and then achieve efficient treatment of the malodorous gas through gradient adjustment of the spray power combined with steering control. While promoting the intelligent adjustment of the deodorization process data, it can also effectively reduce the energy loss in the deodorization process of the malodorous gas through independent control of the spray control unit and the steering control unit and coordinated control, reduce the deodorization cost, and promote the economic benefits of deodorization.
[0033] Then the intelligent deodorization treatment unit controls the air intake valve through the air intake control unit to allow the pre-treated malodorous gas from the outside to be introduced, and the catalytic enrichment coupling reactor 2 and the nano-liquid spray droplets are used to treat and adsorb the malodorous gas, and the gas detector located on the left side of the gas outlet 13 continuously detects the gas quality, and the emission quality detection unit transmits the quality data to the intelligent deodorization treatment unit. While judging whether the gas meets the emission standard, the intelligent deodorization treatment unit also verifies the data of the atomizing nozzle 3 after the treatment parameters are changed to ensure the rapid treatment of the malodorous gas. After the parameters are adjusted, the malodorous gas can be treated once and meet the standards, and the above-mentioned control instructions are maintained until the malodorous gas in the new concentration state enters and is treated, effectively promoting the high applicability deodorization effect on the malodorous gas in different concentration states, thereby ensuring the efficiency and effect of the treatment of the malodorous gas, reducing resource loss, and promoting the actual benefits of the treatment of the malodorous gas.
[0034] When the number of cycles that meet the standard exceeds 3 times or continues to fail to meet the standard, the intelligent deodorization treatment unit will send a data reminder of the abnormal data to the technical personnel through the data output unit and the data port of the aggregate box 14, so that the technical personnel can deal with the abnormality in time, and check the application effect of the catalytic enrichment coupling reactor 2 and the nano solution in time to ensure the effectiveness of its functions. The gas detector is calibrated and verified to ensure the validity and accuracy of its detection data, avoid the illegal emission of odorous gases caused by the failure of the deodorization tower 1, pollute the environment, cause serious loss of resources, cause economic losses, and effectively ensure the safety of the deodorization tower 1 during its application.
[0035] During the process in which the intelligent deodorization treatment unit controls the deodorization tower 1 to perform deodorization operations and controls the atomizing nozzle 3 and the steering control unit 6 for intelligent adjustment, the full data of the deodorization process will be transmitted to the technicians in real time through the data port of the aggregate box 14 via the data output unit, so that the technicians can effectively judge the deodorization status of the deodorization tower 1 at this time based on the data feedback, effectively achieve the monitoring function of the deodorization process, and ensure the safety and effectiveness of the deodorization process.
[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
