Description

Technical Field

[0001] The present application relates to the field of environmental governance technology, and specifically to an environmentally friendly treatment system and method for air pollution control. Background Art

[0002] Dust is a type of particulate air pollutant, consisting of solid particles suspended in gases during thermal processes such as oxidation, sublimation, and evaporation. Its primary components include silicon dioxide, aluminum oxide, iron oxide, calcium oxide, and unburned carbon particles. Large quantities of dust are emitted during coal combustion and industrial production, and are particularly noticeable in converter flue gas and during strong winds in desertified regions.

[0003] Among existing technologies for air pollution control, traditional environmentally friendly treatment systems have many shortcomings. On the one hand, the treatment effect on impurities and acidic gases in smoke is poor, and impurities cannot be fully dissolved and adsorbed, resulting in the exhaust gas still containing a large amount of pollutants, causing continuous pollution to the environment. For example, when treating smoke from converter flue gas, common treatment systems have difficulty in effectively removing acidic gases. These acidic gases, when discharged into the atmosphere, will form acid rain and disrupt the ecological balance. On the other hand, the existing system lacks an accurate evaluation mechanism for treatment effects, and cannot timely understand the dynamic changes in impurity removal during the treatment process, making it difficult to optimize and adjust the treatment process. At the same time, the dust generated during the treatment process is prone to secondary flying, which not only causes environmental pollution, but also increases the difficulty of subsequent cleaning and transportation.

[0026] In order to make the application objectives, features, and advantages of this application more obvious and easy to understand, the technical solutions protected by this application will be clearly and completely described below using specific embodiments and drawings. Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0027] like Figure 1 As shown, the first embodiment of the present invention provides an environmentally friendly treatment system for air pollution control, comprising a collection module, the collection module being connected to a detection module and a pre-processing module, the pre-processing module being connected to a filtration module and an agglomeration module, the detection module being connected to a effectiveness analysis module; the filtration module being connected to the detection module; Collection module, used for collecting smoke and dust; The detection module is used to detect the impurity content in the smoke. At the same time, when detecting the impurity content in the smoke, a pre-processing detection unit and a post-processing detection unit are established. The pre-processing detection unit is used to detect the smoke collected by the collection module to obtain the first level of impurity content, while the post-processing detection unit is used to detect the smoke after the filtration module to obtain the second level of impurity content; The pre-treatment module establishes a Z-shaped duct and a bag dust collector. The Z-shaped duct includes a lower port and an upper port. The smoke is transmitted into the Z-shaped duct through the lower port and then discharged from the upper port of the Z-shaped duct to obtain a layer of treated smoke. The bag dust collector filters the first layer of treated smoke again to obtain a second layer of treated smoke. The filtration module establishes a filter tank, and injects water and sodium carbonate solution into the interior of the filter tank to obtain a filtrate. The fan blades are then used to rotate the filtrate, and the second layer of processed smoke dust is transferred from the lower end of the filter tank to the interior of the filter tank, which will form filter bubbles in the filtrate. At the same time, the fan blades are used to break up the filter bubbles and collect the filtered gas. At the same time, the sodium carbonate solution reacts chemically with the smoke dust, thereby absorbing the acidic gas in the smoke dust and obtaining a third layer of processed smoke dust. At the same time, the concentration of the sodium carbonate solution in the filter tank is regularly detected to obtain the real-time concentration and set a concentration threshold. When the real-time concentration is lower than the concentration threshold, a signal to replace the filtrate and sodium carbonate solution is transmitted to the staff. The fan blades can be multi-layered so that the fan blades can fully contact the filter bubbles during rotation, thereby fully breaking them up.

[0028] The agglomeration module is used to collect the dust generated in the pretreatment module, then establish an agglomeration threshold and collect the weight of the dust. When the weight of the dust is greater than the agglomeration threshold, water will be sprayed on the dust to cause the dust to agglomerate and form block dust. The agglomeration module is a simple pull-out box, and the water spraying structure is an intelligent sprinkler. Its working principle is that the signal sent by the controller will drive the motor to operate, and the motor drives the rotation or swing of the sprinkler through transmission devices such as gears or belts to achieve water spraying at different angles and ranges. When the motor is started, the sprinkler switch will be turned on synchronously to spray water from the intelligent sprinkler.

Based on the primary impurity content and secondary impurity content, the smoke dust treatment effect is calculated to obtain the current effectiveness value.

When the weight of the dust is greater than the clumping threshold, water will be sprayed on the dust to cause the dust to agglomerate to form block dust, collect the effects of different treatment methods on smoke treatment, calculate the smoke treatment effect based on the first impurity content and the second impurity content, and obtain the current effectiveness value; It should be noted that the detection module can accurately evaluate the removal effect of the treatment system on smoke impurities, providing key data support for subsequent effectiveness analysis. The use of the pretreatment module helps to initially separate some larger particle impurities, while extending the residence time of the smoke in the pipeline, improving the initial treatment effect. The use can more fully dissolve and adsorb impurities in the smoke, more efficiently purify the acidic gas in the smoke, and use the agglomeration module to avoid secondary dust flying and causing pollution, while also facilitating subsequent cleaning and transportation.

[0031] The second embodiment of the present invention provides an environmentally friendly treatment system for air pollution control, which, based on the above-mentioned first embodiment, further includes: When the primary impurity content and secondary impurity content in the detection module are obtained, a partition detection unit will be established. The partition detection unit is used to analyze the time required for processing the smoke and dust to obtain the processing time. Let the processing time be , The unit is minutes, and then 、 and The content of impurities in the smoke is detected at a certain time and three content values are obtained; After the content value is obtained, calculate the smoke impurity value, set The content of impurities in smoke is detected at the time of ,set up The content of impurities in smoke is detected at the time of ,set up The content of impurities in smoke is detected at the time of , assuming the smoke impurity value is :

[0032] The smoke impurity value is calculated according to the above formula, and then the smoke impurity value is converted into the corresponding impurity content, thereby obtaining the first impurity content and the second impurity content; When the pre-treatment module obtains a layer of processed smoke, the Z-shaped pipe is split. The Z-shaped pipe is divided into a first turning port and a second turning port from the lower port to the upper port. An ash drop port is provided at the lower end of the first turning port. The pipe from the first turning port to the lower port in the Z-shaped pipe is inclined, and the height of the pipe close to the lower port is lower than the height of the pipe close to the first turning port. When the filtrate in the filter module is injected into the interior of the filter tank, activated carbon is added to the interior of the filtrate to improve the filtration effect of the filtrate on smoke and dust; Specific work flow: Establish a partition detection unit, use the partition detection unit to analyze the time required to process the smoke and dust, and obtain the processing time. 、 and The impurity content in the smoke is detected at a certain time to obtain three content values, the smoke value is calculated, and then the smoke value is converted into the corresponding impurity content, thereby obtaining the first impurity content and the second impurity content, and the Z-shaped pipe is split. The Z-shaped pipe is divided into a first turning port and a second turning port from the lower port to the upper port, and an ash drop port is provided at the lower end of the first turning port. The pipe from the first turning port to the lower port in the Z-shaped pipe is inclined, and the height of the pipe close to the lower port is lower than the height of the pipe close to the first turning port. Activated carbon is added to the inside of the filtrate to improve the filtration effect of the filtrate on the smoke; The detection module helps to gain a deeper understanding of the dynamic trend of impurity removal in the entire treatment process, providing more accurate data support for optimizing the treatment process and adjusting the treatment parameters. The pretreatment module is used to enhance the separation effect of large particle impurities, reduce the burden on subsequent treatment modules, and significantly improve the filtration effect of smoke and dust, thereby enhancing the purification capacity of atmospheric pollutants and enabling better pollution control of the atmosphere.

When the cleaning signal is transmitted to the staff; After receiving the cleaning signal, the staff needs to clean the agglomerated dust. At the same time, the place where the dust is agglomerated can be set as a box. When the agglomerated dust needs to be cleaned, the box can be directly replaced. When calculating the current effectiveness value in the effectiveness analysis module, it is necessary to first calculate the difference between the first impurity content and the second impurity content, and then use the difference as the numerator and the first impurity content as the denominator for calculation. Suppose the first impurity content is , assuming the double impurity content is , set the current performance value to :
