Normalization of dust pollution control, dust monitoring equipment helps port dust pollution control
In August 2020, the International Environmental Protection Organization Asia Clean Air Center released a report '2019 Blue Port Pioneer: Evaluation of Blue Sky Action Capacity of Typical Chinese Ports' in Beijing. Among them, the main typical port cities have an annual PM2.5 average in 2019. The proportion of meeting the concentration standard is 30%, while that of a typical inland port city is only 11%. In addition, the dust problem of dry bulk terminals is also more prominent.
'China Mobile Source Environmental Management Annual Report 2020' shows that nitrogen oxides, particulate matter and hydrocarbons (HC) emitted by ships account for 28.2%, 24.2% and 19.8% of emissions from non-road mobile sources, respectively , Fugitive dust is an important part of air pollutants PM2.5 and PM10.
Data shows that the waste gas emitted by ships in port cities such as Shenzhen, Shanghai, and Hong Kong accounts for 20%-40% of urban air pollutant emissions.
It can be seen that doing a good job in port and terminal dust pollution control is the key to improving ambient air quality, especially the dust pollution of bulk cargo terminals.
Another reason why port dust pollution must be cured is that with the adjustment and optimization of the transportation structure, railway and water transportation will become the main means of bulk cargo transportation in my country. In September 2018, the 'Three-Year Action Plan for Promoting the Adjustment of Transportation Structure (2018-2020)' issued by the General Office of the State Council proposed that the main direction of the promotion of bulk cargo transportation 'revolution to iron and water' as the main direction, and strive to pass the three-year period. , The volume of road transportation of bulk cargo in coastal ports decreased by 440 million tons.
In response to the above problems, industry insiders have also put forward corresponding suggestions.
1. Port dust pollution control facilities need to be further strengthened. Port yards should turn on environmental protection and dust suppression equipment on a daily basis, strengthen the control of dust problems during loading and unloading of goods, vehicle washing, etc., regulate vehicle cover before departure; install dust online monitoring equipment in port yards and roads, and pass relevant information platforms Open real-time monitoring data.
Second, establish and improve the long-term management mechanism of dust pollution in ports and wharfs. In view of the dust problem, port companies should strengthen the dust control measures in the transportation link. If possible, they can be equipped with online dust monitoring equipment for real-time monitoring and open the real-time monitoring results to the public for public supervision.
The dust monitoring equipment meets the above-mentioned port dust monitoring requirements. The equipment is mainly composed of a dust monitoring unit, a noise monitoring unit, a weather monitoring unit, a data acquisition and processing unit, a data transmission unit, an LED screen display unit, a solar power supply unit, and a video character overlay unit. PM10, environmental temperature and humidity, carbon dioxide concentration, atmospheric pressure, wind speed, direction, noise and other parameters monitoring and video monitoring and other functions, to achieve port environmental parameter monitoring, display, data upload, video overlay functions, and can be connected to related departments, Upload the data to the monitoring platform in real time to realize 24-hour real-time monitoring of the port environment.
The dust monitoring equipment is equipped with a dust online monitoring cloud platform, which can integrate multi-element data on the spot to achieve centralized monitoring. It can be viewed on multiple terminals on the computer and mobile phones, which is convenient for port managers to understand Port environment information. At the same time, the platform also has the following functions:
Large-screen visualization: visually display the area’s environmental information, the city’s factor average, equipment real-time information, and equipment list information.
Electronic map: Visually display all the dust monitoring points in the area, and the list on the left can quickly query the required sites. Move the mouse to a site to view the name of the site, click on a site to view real-time dust monitoring data, site basic information, parameter change trends, etc.
Real-time monitoring: Collect real-time data of various sites, and present the site conditions to users in a clean and intuitive manner through real-time monitoring and on-site monitoring functions.
Real-time data query: Quickly find the site and select the parameter type that needs to be viewed for data query. The page presents nearly 24 hours of hourly average data in two intuitive forms, a list and a line graph. It is convenient to view the change curve of the recent parameter concentration, and analyze the data conveniently and quickly.
Single-site multi-parameter query: You can query the historical data of all monitoring sites in the jurisdiction. Select the corresponding time range and data type (hourly data, daily data, monthly data, quarterly data) for query according to your needs. The line chart and pie chart visually display the fluctuations in the time period, which is convenient for predicting future trends; the list displays specific data, and supports export and analysis.
Alarm query: The table displays all alarm events and supports the export function. You can also quickly search for alarm events by selecting the site and alarm type.
Site ranking: According to different parameters, the sites are ranked in ascending order according to the concentration of different parameters. The top 10 and the bottom 10 are clear at a glance, simplifying the comparison link and making it easier to manage. Provides a list representation, which can be exported.
Statistical analysis: Realize the system's statistics, comparison and analysis of existing data. Specific functional sub-modules include: comparison with the city average, monthly average year-on-year/month-on-month ratio, particle concentration distribution range, equipment query, transmission efficiency query, and administrative district average comparison. In order to meet different needs, the comparison provides three forms of histogram, line chart, and list, and supports the export function.
In the control of dust pollution, monitoring is only an aid. The main work must start from the control of the source of dust pollution, start the normalization of dust pollution control, and carry out systematic design and precise control.
At the same time, as the recent research of Rika Sensors shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
