Problems solved by technology

Sprinkling water to suppress dust not only causes a lot of waste of water resources, but also due to the high temperature in summer and fast evaporation in northern my country (generally, it can only be sprayed for about 10 minutes at a time), while the temperature in winter is low and it is easy to freeze, so its practical application is greatly affected. Restrictions: the thatch cover woven cloth of bulk materials has low strength, smoothness, light weight, easy to go for a ride, short service life and high cost, which not only causes waste of resources, but also has troublesome processes of covering and dismantling the cover, which is not conducive to increasing the speed of operation. The one-time investment for wind-shielding and dust-suppressing walls and the construction of closed structures for dust-suppression is huge, and it cannot capture the dust floating in the air. For the operation area where new dust is constantly generated, its dust-suppressing ability is limited; chemical dust-suppressant It has a

Abstract

The invention discloses a high-polymer dust suppressant, belonging to the field of dust suppression. The high-polymer dust suppressant comprises a polymer molecule (C18H29O3S)m-(C3H5)n-(C3H4N)z, wherein m>=10, n>=115, and z>=15; and the polymer molecule has a spacial three-dimensional network structure. The high-polymer dust suppressant can prevent and treat open dust sources, can be widely used in coal/metal/nonmetal mining areas, mineral slag stock grounds, coal/ore powder transportation, mineral earthwork storage unloading areas, building evacuation, under-construction road way sides, thermal power plants, cement plants, steel plants, metallurgic plants, dust workshops, artificial beaches, desertification areas and other locations, has favorable wind erosion resistance and compression strength, can display the dust suppression effect for a long time, avoids environmental pollution caused by flying dust or abundant waste of resources (such as coal powder), and has the characteristic of environment friendliness.

Description

technical field [0001] The invention relates to a dust suppressant, in particular to a polymer dust suppressant. Background technique [0002] With the development of the economy, dust pollution has become the main pollutant that leads to poor air quality and is difficult to control. Pollution caused by flying dust can easily lead to the destruction of ecological balance, affect the physical and mental health and life safety of surrounding people, cause civil disputes, shorten the service life of operating machines, and restrict regional economic development. Therefore, the importance of dust prevention and control is becoming more and more prominent. my country has a long history of research on stationary industrial pollution sources, especially particulate matter emitted from energy combustion and production processes, and has a relatively complete set of testing, treatment, and management methods. However, there is no systematic research on the dust pollution and control...
