Description

Technical Field

[0001] The invention belongs to the technical field of environmental dust removal and relates to an integrated system for controlling and managing regional unorganized dust emissions. Background Art

[0002] Unorganized dust emission refers to dust that is emitted irregularly without passing through the exhaust pipe or within 15 meters of the exhaust pipe. Unorganized dust emission is an important component of haze. About 1 / 3 of the PM2.5 sources in northern cities come from unorganized dust emission. Dust floating in the air is easily adhered to nitrogen oxides, sulfur oxides, etc. in the air to form toxic aerosols, and can cause regional air pollution through transmission, thereby seriously polluting the regional atmospheric environment and posing a potential huge threat to human health.

[0003] In places such as metallurgy, building materials, metal mines, quarries, construction waste treatment, building blasting, ports and industrial yards, a large amount of fine particles and ultra-fine particle powders are released due to human production activities, and after contacting with the air, they are disturbed by the air and released into the air to form dust, which is a common unorganized emission of dust. In addition, in the industrial production process of industries such as steel, metallurgy, thermal power, cement, sand and gravel aggregates, there are often unorganized dust emission processes such as unloading, shoveling, dropping, stacking, batching, belt transfer, crushing, screening, drying, grinding and sintering. The above-mentioned unorganized dust emission has the characteristics of unconcentrated emission, irregularity, uncertain diffusion, and a large diffusion range, which can easily cause non-point source pollution. Therefore, it is extremely difficult to effectively monitor and control it, which also leads to the traditional single-point dust removal technology such as bag / cartridge dust collector, electrostatic precipitator, water spray / fog and other dust removal equipment. It is difficult to effectively play the ideal effect when facing unorganized dust emission. Summary of the invention

[0004] In view of the shortcomings of the prior art mentioned above, the purpose of the present invention is to provide an integrated control and management system for regional unorganized dust emissions monitoring, control and intelligent management, which is used to solve the problem of lack of effective control of regional unorganized dust emissions in the prior art, through systematic software and hardware integration, big data analysis and decision-making, platform display and control to achieve intelligent control of regional unorganized emissions.

[0121] Example 1

[0122] like Figure 1 As shown, an integrated system for controlling and treating regional unorganized dust emissions according to an embodiment of the present invention is set up in a large iron ore plant with an area of ​​5 square kilometers, including a control mechanism and several sets of monitoring mechanisms and treatment mechanisms set up at different dust-generating points. Since the dust-generating methods of different dust-generating points are quite different, the specific equipment conditions of the monitoring mechanisms and treatment mechanisms configured at different dust-generating points are also quite different, and the control methods adopted by the control mechanisms are also quite different.

[0123] Specifically, in the mining and stockpile operation areas of large iron ore plants, the dust is produced in a completely open environment, and dust can diffuse freely to the surrounding environment. The monitoring mechanism mainly includes data acquisition modules and data transmission modules. The data acquisition module includes a GPRS locator and sensors. The sensors are mainly selected from optical machine vision recognition sensors, light scattering dust concentration sensors and atmospheric temperature and pressure flow sensors.

[0124] The information collected by the data acquisition module includes environmental parameters and field parameters. The collected environmental parameters include but are not limited to wind speed, wind direction, temperature, humidity, air pressure, PM10, PM5, PM2.5, PM1, and total concentration of particulate matter in the air (TSP); the collected field parameters include but are not limited to displacement detection, coordinate detection or optical image recognition.

[0125] The data transmission module is selected from a wireless communication terminal, and the wireless communication terminal mainly includes any one or more combinations of 3G, 4G, GPRS, and GSM wireless communication terminals.

[0126] At the same time, in the mining and stockpile operation areas of large iron ore plants, the management mechanisms set up mainly include dust removal modules, power modules and early warning modules. The power module is connected to the dust removal module and the main engine module respectively, and the early warning module is connected to the main engine module. The power module is used to receive the analysis result instructions sent by the main engine module and send operation instructions to the dust removal module to make it run. The early warning module is used to issue an early warning after receiving the analysis result instructions sent by the main engine module.

[0127] The dust removal module mainly includes any one or more combinations of windproof and dust suppression devices, fog cannons, wheel washers or road cleaning vehicles, wherein the windproof and dust suppression devices are selected from any one or more combinations of dustproof nets, wind barriers, windbreak walls, expanded closed material guide troughs or windproof ceilings, and the windproof and dust suppression devices have the function of automatically suppressing dust in places such as piles or bulk material loading and unloading; the fog cannon is a conventional fixed fog cannon or mobile fog cannon, and the wheel washer is a conventional high-pressure wheel washer, both of which can be purchased on the market, and the fog cannon and wheel washer have the function of automatically suppressing dust on the road. The road cleaning vehicle is a conventional sweeper, vacuum truck, sprinkler and spray truck, which can be purchased on the market, and the road cleaning vehicle is used to suppress dust on the road.

[0128] The power module is selected from any one or more combinations of water pumps, air compressors, and servo motors. The power module is used to control the opening, closing, and rotation of the dust removal module and provide water and air sources to the dust removal module; the early warning module is selected from any one or two combinations of indicator lights or alarms.

[0129] Since the mining and stockpiling operation areas of large iron ore plants are large and the amount of dust generated is also large, it is almost impossible to seal them all or completely enclose them. In industry, wind and dust suppression devices are generally used, such as dust nets, wind barriers, windbreak walls, expanded closed material guide troughs or windproof ceilings to enclose the workplace for semi-sealing to reduce the rate of dust diffusion to the surrounding areas, and at the same time prevent natural wind from carrying dust to the surrounding areas to prevent secondary pollution to the surrounding areas.

[0130] At the same time, GPRS locators are installed on production equipment and dust removal modules in the mining and material pile operation areas. When displacement of production equipment such as excavators, forklifts, material guide vehicles, unloading vehicles, grabs, etc. is detected, the control mechanism will automatically control the adjacent dust removal modules such as fog cannons and road cleaning vehicles according to the set program to spray dust on the mobile production equipment to prevent dust dispersion. For example, the GPRS locator is installed on the road cleaning vehicle. The GPRS locator transmits the coordinates of the road cleaning vehicle to the host module in real time through the data transmission module. When the dust concentration on the road exceeds the standard, the host module will automatically search for the road cleaning vehicle closest to the dust exceeding the standard point according to the coordinates, and automatically send cleaning scheduling information to the road cleaning vehicle to command the road cleaning vehicle to clean the dust exceeding the standard point.

[0131] Optical machine vision recognition sensors are installed at appropriate locations in the mining and stockpile operation areas. The optical machine vision recognition sensors are mainly selected from industrial cameras, video cameras or cameras and other image and video monitoring equipment. They can monitor the operation area from all angles and cover the entire area. The control mechanism analyzes the captured images and videos at regular intervals (which can be adjusted by manual input through the I / O module). When unorganized dust is generated, the GRB of the pixels on the screen changes. At this time, the host module will use power modules such as high-pressure water pumps and servo motors according to the preset evaluation formula and program to automatically control the adjacent fog cannon or road cleaning vehicle based on GPRS coordinate positioning to perform dust reduction operations on the pixel area where the GRB changes, and at the same time send out an alarm signal for exceeding the standard.

[0132] When cameras and other monitoring equipment detect that excavators, forklifts, material guide trucks, unloading trucks, etc. are leaving the mining and material pile operation area, in order to prevent the large amount of dust carried on their wheels from causing dust and polluting the factory roads, the host module will use power modules such as water pumps and air compressors to automatically control the high-pressure wheel washing machine to clean the vehicle tires.

[0133] The light scattering dust concentration sensors and atmospheric temperature and pressure flow sensors installed at the stacking points, unloading points and feeding points in the mining and stockpiling operation areas can monitor in real time the wind speed, wind direction, temperature, humidity, air pressure, PM10, PM5, PM2.5, PM1, total concentration of particulate matter in the air (TSP) and other environmental parameters at that location. When the environmental parameters such as dust concentration are greater than the preset parameter thresholds, the control mechanism will use power modules such as high-pressure water pumps and servo motors to automatically control nearby fog cannons or road cleaning vehicles based on GPRS coordinate positioning to perform fixed-point dust reduction operations.

[0134] In the crushing operation area of ​​a large iron ore plant, the dust generation method is generally limited to semi-enclosed mechanical equipment or workshops in the factory building. The dust diffusion space and path are relatively limited, and the monitoring and governance agencies required are different from those set up in the mining and material pile operation area. The monitoring agency mainly includes a data acquisition module and a data transmission module, wherein the data acquisition module includes a GPRS locator and a sensor, and the sensor is mainly selected from any one or more combinations of light scattering dust concentration sensors, belt running sensors, material temperature and humidity sensors, material weight sensors, power sensors or flow sensors.

[0135] The information collected by the data acquisition module includes environmental parameters, process parameters and dust removal equipment parameters, among which the collected environmental parameters include but are not limited to PM10, PM5, PM2.5, PM1 and total concentration of particulate matter in the air (TSP); the collected process parameters include but are not limited to material density, temperature, humidity, bulk density, wettability, repose angle, production flow rate, production frequency; the collected dust removal equipment parameters include but are not limited to equipment start and stop status, equipment power consumption, equipment pressure, equipment outlet concentration, water / gas consumption, etc.

[0136] The data transmission module is selected from any one or more combinations of data lines or signal lines.

[0137] At the same time, in the crushing operation area of ​​a large iron ore plant, the management mechanism set up mainly includes a dust removal module, a power module and an early warning module. The power module is connected to the dust removal module and the main engine module respectively, and the early warning module is connected to the main engine module. The power module is used to receive the analysis result instructions sent by the main engine module and send operation instructions to the dust removal module to make it run. The early warning module is used to issue an early warning after receiving the analysis result instructions sent by the main engine module.

[0138] The dust removal module is mainly selected from the BASV comprehensive dust suppression device, which mainly includes any one or more combinations of biological nanofilm dust suppression devices, ultra-sealed dust suppression devices, cloud and mist dust suppression devices, and dry / wet dust collection devices. The biological nanofilm dust suppression device and the ultra-sealed dust suppression device have the function of automatically suppressing dust in the factory production process area. The cloud and mist dust suppression device has the function of automatically suppressing dust in places such as piles or bulk material loading and unloading. The dry / wet dust collection device has the function of automatically collecting dust at the dust generation point.

[0139] The power module is selected from any one or more combinations of water pumps, air compressors, frequency converters, servo motors or fans. The power module is used to control the opening, closing and rotation of the dust removal module and provide water and air sources to the dust removal module; the early warning module is selected from any one or two combinations of indicator lights or alarms.

[0140] The production line of the crushing operation area of ​​the iron ore plant is relatively complex, generally including crushers for crushing materials, screeners for screening materials, conveyor belts for transporting materials and silos for storing materials. According to the different process characteristics and equipment characteristics of the production line, it is necessary to reasonably configure the data acquisition module, dust removal module and power module, and reasonably design the monitoring parameters and control procedures to optimize the dust removal efficiency while achieving the purpose of saving water and electricity.

[0141] First of all, the iron ore excavated by mining operations is not convenient for direct storage, transportation or use due to its large particles and uneven particle size. It is generally necessary to reduce the particle size of the material after passing through the crusher to facilitate subsequent industrial operations. During the crushing operation, dust will be generated inside. At this time, data acquisition modules, dust removal modules and power modules need to be installed at the inlet and outlet of the crusher. Among them, the data acquisition module mainly uses GPRS locator, light scattering dust concentration sensor, power sensor and flow sensor; the dust removal module mainly uses biological nanofilm dust suppression device, and the power module mainly uses water pump, air compressor and inverter.

[0142] During the dust removal process of the crusher, the parameters mainly monitored by the data acquisition module include the GPRS geographic coordinates of the production and dust removal equipment, PM10, PM5, PM2.5, PM1, the total concentration of particulate matter in the air (TSP), and the equipment start-up and shutdown status, equipment power consumption, equipment pressure, equipment outlet concentration and water / gas consumption and other environmental and equipment information. When the monitored dust concentration is greater than the threshold of the host module, the host module will use the power modules such as water pumps, air compressors and inverters according to the built-in program to intelligently and automatically control the bio-nanofilm dust suppression device at the dust-producing point based on the GPRS geographic coordinates to spray the bio-nanofilm, and automatically adjust the equipment pressure, power, outlet nanofilm concentration, water / gas consumption and other parameters according to the change of dust concentration, so as to achieve the purpose of saving water and energy. In this embodiment, the ejected bio-nanofilm enters the crusher with the material. The bio-nanofilm is a double ionosphere film. The dust generated during the crushing process will be adsorbed by the bio-nanofilm, thereby increasing the weight of the dust to form a cohesion and sedimentation effect, accelerating the falling speed of the dust, and achieving the effect of dust removal before the dust is dispersed.

[0143] The crushed materials then enter the screening machine for screening, and the materials are classified according to different particle sizes. During the screening process, the dust adhering to the surface of the material is re-lifted by the mechanical vibration. At this time, the data acquisition module, dust removal module and power module need to be installed at the inlet and outlet of the screening machine. Among them, the data acquisition module mainly uses GPRS locator, light scattering dust concentration sensor, power sensor and flow sensor; the dust removal module mainly uses cloud and fog dust suppression device, and the power module mainly uses water pump, air compressor and inverter.

[0144] During the dust removal process of the screening machine, the main parameters monitored by the data acquisition module include the GPRS geographic coordinates of the production and dust removal equipment, PM10, PM5, PM2.5, PM1, the total concentration of particulate matter in the air (TSP), and equipment start and stop status, equipment power consumption, equipment pressure, and water / gas consumption and other environmental and equipment information. When the monitored dust concentration is greater than the threshold of the host module, the host module will use power modules such as water pumps, air compressors and inverters according to the built-in program to intelligently and automatically control the cloud and fog dust suppression device at the dust-producing point based on the GPRS geographic coordinates to spray dry fog, and automatically adjust the equipment pressure, power, water / gas consumption and other parameters according to the change of dust concentration.

[0145] Due to the high dust concentration, large dust emission area and difficulty in sealing at the feed inlet of the screening machine, the cloud mist dust suppression device installed at the inlet and outlet of the screening machine will spray dense dry mist on the dust and form a fog blanket to fully cover the inlet and outlet, which can effectively prevent the dust from emitting outward. At the same time, the dust particle size generated during screening is generally 0.1-80μm. When water droplets with a particle size much larger than that of dust particles come into contact with the dust in a spraying state, the dust will be driven forward by the air flow next to the water droplets without colliding with the water droplets. In this embodiment, the particle size of the dry mist is 0.5-100um, and the value range of the particle size of the dry mist is closer to the particle size of the dust. The dry mist is not easily affected by the airflow in the spraying state, and the dry mist is easy to quickly capture the dust. The dry mist aggregated on the outside of the dust is a protective layer formed on the outside of the dust and can collide and agglomerate with each other to form larger water mist particles, thereby accelerating the aggregation and sedimentation of the dust in the air, thereby accelerating the aggregation and sedimentation of the dust in the air, and greatly reducing the use of water, thereby achieving the purpose of saving water and energy.

[0146] After the materials are classified by the screening machine, the materials of different particle sizes are transported to the stacker by the corresponding conveyor belt, and then stored in the corresponding silo by the stacker. Due to the fast running speed of the materials on the conveyor belt, the dust adhering to the surface of the materials will still be raised again, and there is a large drop at the inlet and outlet of the stacker, and the dust emission phenomenon is serious. At this time, data acquisition modules, dust removal modules and power modules need to be installed at the conveyor belt, the inlet and outlet of the stacker and the feed inlet of the silo. Among them, the data acquisition module mainly uses GPRS locator, light scattering dust concentration sensor, belt operation sensor, material temperature and humidity sensor, material weight sensor, power sensor and flow sensor; the dust removal module mainly uses ultra-sealed dust suppression device and dry / wet dust collection device, and the power module mainly uses water pump, air compressor, inverter and fan.

[0147] During the dust removal process of conveyor belt transportation and silo stacking, the main parameters monitored by the data acquisition module include GPRS geographic coordinates of production and dust removal equipment, PM10, PM5, PM2.5, PM1, total concentration of particulate matter in the air (TSP) and other environmental information, and process information such as material density, temperature, humidity, pile density, wettability, repose angle, production flow, production frequency, as well as equipment information such as equipment start and stop status, equipment power consumption, equipment pressure, and water / gas consumption.

[0148] When the monitored dust concentration is greater than the preset threshold in the host module, the host module will use the power modules such as water pumps, air compressors, frequency converters and fans according to the built-in program to intelligently and automatically control the dry / wet dust collection device at the dust-generating point based on the GPRS geographic coordinates for dust removal, and automatically adjust the equipment pressure, power, water / gas consumption and other parameters according to the change of dust concentration. At the same time, the density, temperature, humidity, bulk density, wettability, repose angle, production flow, production frequency and other process information of the materials in the conveyor belt and silo are monitored. When the monitored process information deviates from the preset threshold range in the host module, the host module will analyze the dust removal behavior in the front-end crushing and screening operations according to the built-in algorithm, and intelligently and automatically control all production and dust removal equipment in the crushing operation area, screening operation area, conveyor belt operation area and silo stacking operation area to adjust until all process parameters are restored to the preset threshold range.

[0149] Since the material conveyor belts of large iron ore plants convey a large amount of materials at a high speed and can be several thousand meters long, it is very easy to cause the dust adhering to the materials to be raised again. It is necessary to set up an ultra-sealed dust suppression device so that the ultra-sealed dust suppression device and the conveyor belt form a material transmission space with a closed effect, thereby preventing the dust from floating. The ultra-sealed dust suppression device of this embodiment can adopt the ultra-sealed dust cover in the Chinese invention patent "Dust Suppression Belt Conveyor", and the patent number of the "Dust Suppression Belt Conveyor" is ZL201310413139.4. The ultra-sealed dust cover is a non-powered device, which is easy to use and easy to clean.

[0150] Since the stacker has a fast loading speed and a large drop in the inlet and outlet, the dust concentration it generates is high and relatively concentrated. It is necessary to set up a dry / wet dust collection device, seal the stacker feed port and set up a dust hood. When the dust concentration in the hood is detected to be greater than the preset threshold in the host module, the host module will automatically control the start and stop of the power module such as the water pump or fan connected to the rear end of the dry / wet dust collection device and its operating power according to the built-in algorithm, and absorb the dust in the hood to the dry / wet dust collection device, and settle the dust in the device. The outlet of the dry / wet dust collection device is connected to the outlet of the feeder and the inlet of the silo. The settled dust eventually enters the silo for recycling and reuse, reducing material waste and dust removal costs.

[0151] Materials with high requirements for humidity control, such as limestone, are generally recycled using a dry dust collector. In this embodiment, a dry dust collector is used, which mainly includes a cartridge dust collector, a bag dust collector, and a plastic-sintered plate dust collector, and compressed air is used to perform pulse backblowing on the above-mentioned devices. The dust adhering to the filter bag / plate eventually settles in the clean room of the above-mentioned device and is returned to the silo for reuse. It is worth pointing out that for flammable and explosive materials such as magnesium powder, aluminum powder, etc., a wet dust collector can be used. The wet dust collector is generally a self-excited dust collector and a Venturi dust collector. The dust deposited in the water tank can be returned to the silo for reuse after drying, which can control dust pollution while avoiding material loss.

[0152] The control mechanism of this embodiment includes a host module, a storage module and an I / O module, wherein the storage module is connected to the host module and the data transmission module respectively, and the host module is also connected to the I / O module. The storage module is used to receive the dust data information transmitted by the data transmission module for storage and input the dust data information into the host module, the I / O module is used for human-computer interaction and inputs the preset judgment conditions into the host module, and the host module is used to analyze the received dust data information with the preset judgment conditions.

[0153] Specifically, the host module in this embodiment is a commercially available single-chip microcomputer. The storage module is selected from any one or more combinations of random access memory, read-only memory or external memory. In addition, a cloud server can be built or rented according to actual needs. The I / O module is used for human-computer interaction and is selected from any one or more combinations of keyboard, mouse, touch screen or monitor. The modules in the control mechanism are connected using serial communication and network communication principles.

[0154] In summary, conventional unorganized dust control technologies generally include fog cannon equipment, dry fog dust suppression equipment and road sprinklers, etc. Such equipment or technologies can generally only be used for dust removal and dust suppression through manual operation or embedded PLC programs. It can be seen that the control method of conventional unorganized dust control technology is relatively simple, does not include built-in algorithms and central control systems with powerful analytical and computing functions, and cannot respond and adjust in time according to changes in environmental parameters, process parameters, dust removal equipment parameters and on-site parameters, and cannot intelligently and adaptively control the start, stop and operation of dust removal equipment.

[0155] The integrated system for regional unorganized dust emission control and management provided by the present invention can reasonably configure and expand monitoring and management mechanisms according to the environmental parameters, process parameters, dust removal equipment parameters and on-site parameters of industrial unorganized dust emissions, and can effectively and intelligently and adaptively suppress the dust generated by each dust-producing point, while achieving the purpose of saving water and energy and reducing dust suppression / dust removal costs.

[0156] The regional unorganized emission dust control integrated system provided by the present invention not only adopts a modular structure and is easy to expand, but also has big data processing functions and machine deep learning functions. It can provide personnel operation or built-in algorithms through the I / O module according to the dust data information collected by the monitoring agency, and rely on the host module to deeply mine data rules and guide the adaptive operation of the governance system, establish a pollution emission inventory model, an environmental factor tracing model, and an atmospheric environment simulation model, and realize the automatic learning and adjustment of the model, pollution tracing prediction, dust removal control decision-making and system scheduling decision-making functions. Therefore, the present invention effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.

[0157] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
