Problems solved by technology

[0002] The existing smog control method is mainly to reduce emissions. However, emission reduction will inevitably be restricted by many factors such as production technology level, social lifestyle, and natural environment. It often takes a long process to achieve a satisfactory emission reduction level.
[0003] Basin cities are prone to long-term smog retention due to special terrain that restricts air flow, and cannot spread in time, causing unnecessary smog hazards

Embodiment 1

[0017] The first embodiment of the present invention is based on the smart grid of the northern basin urban dry haze treatment method is to spray water mist to the northern basin cities that are suffering from dry haze at night on a sunny day to increase the moisture content in the air in the basin; The spraying of water mist is powered by the low valley electricity of the urban smart grid at night. Due to the low level of the basin city, the increase of air moisture in the air cannot be dissipated, especially at night, as the temperature drops, it can not only sink and mix with the low-level air, but also spread to the valley floor of the basin city, which can be mixed with smog. Adequate diffusion contact can break the balance of moisture and mass in the long-term haze: on the one hand, the increased moisture will be absorbed by the fine dust in the haze, increase the proportion of the fine dust, and promote sedimentation; on the other hand, the increased moisture can As the ...

Embodiment 2

[0024] The second embodiment of the present invention is based on the smart grid of the northern basin urban dry haze treatment method and the difference between the above-mentioned embodiment one is that the parallel cascaded marine aquaculture ponds between adjacent pumping stations are marine animal and marine plant breeding ponds And marine prokaryotic breeding ponds.

[0025] Specifically, the marine plant breeding pond and the marine prokaryotic breeding pond are respectively located in the upstream section and the downstream section of the parallel cascaded marine aquaculture pond between the adjacent pumping stations, and the marine animal breeding pond is connected to the adjacent pump stations. The middle reaches of the cascaded marine aquaculture ponds between stations;

[0026] Or the marine plant breeding pond or the marine prokaryotic breeding pond is located in the downstream section of the parallel cascaded marine aquaculture pond between the adjacent pumping statio...

Abstract

The invention relates to an intelligent power network-based northern basin city dry-type haze treatment method. In order to solve haze problems, at night of a clear day, water mist is sprayed to a northern basin city suffering from dry-type haze so that air in the basin has high water content. The sprayed water mist is driven through night off-peak electricity of a city smart power network. A water source of the sprayed water mist comprises fresh water produced from the existing city surface water source or from seawater through reverse osmosis. The reverse osmosis method utilizes night off-peak electricity of a city smart power network as powder. From a seaside water source to a basin city seawater reverse osmosis-based fresh water preparation device, multiple pumping stations for seawater conveying are orderly cascaded. Between the adjacent pumping stations, multiple parallel cascaded seawater-culture ponds allowing seawater self-flowing are connected in series from upstream to downstream. The pumping stations are driven through night off-peak electricity of the city smart power network. The method fully utilizes off-peak electricity of the city smart power network, realizes treatment on haze without increasing of city energy use and water resource burden, produces seawater culture products and sea salt as side products, provides bittern for city pavement ice prevention, substantially improves a city atmosphere environment and has good input-output benefits.

Description

Technical field [0001] The invention relates to a smog treatment method, in particular to a dry smog treatment method in northern basin cities based on a smart grid. Background technique [0002] The existing smog control methods are mainly emission reduction, but emission reduction will inevitably be restricted by many factors such as production technology level, social lifestyle, natural environment, etc. It often takes a long process to reach a satisfactory level of emission reduction. . [0003] Due to the special terrain that restricts air flow in basin cities, it is easy for the smog to stay for a long time and cannot spread in time, causing unnecessary smog hazards. Summary of the invention [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a smart grid-based urban dry haze treatment method in the northern basin that does not increase the burden of urban energy and other resources. [0005] In order to ac...
