Integrated environment-friendly dust removing system suitable for mixing station and control system and control method thereof

Abstract

The invention relates to the technical field of mixing-station smoke dust and waste gas treatment, and discloses an integrated environment-friendly dust removing system suitable for a mixing station.The integrated environment-friendly dust removing system comprises a dust removing device and multiple smoke-dust collecting units connected with the dust removing device through pipes respectively; dust is integrated to an environment-friendly dust removing system and is uniformly treated, the treating cost and the technology difficulty of asphalt smoke are greatly reduced, treating and discharging of whole smoke dust and waste gas of the mixing station meet the environmental-protection standard, smoke-dust collecting matter can be effectively recycled and used for a stable soil layer of a subgrade, zero discharging of waste is achieved, secondary pollution is avoided, the environmental protection cost is effectively reduced, and the system is capable of saving energy, economical and environmentally friendly; automatic intelligent controlling is effectively achieved through a control system and method of the integrated environment-friendly dust removing system, all control units and modules are synergistically matched, according to states of dust source points, frequency converting control is conducted, the wind pressure, wind speed and wind volume of running of equipment are automatically adjusted, it is guaranteed that smoke dust and waste gas are effectively collected and removed, the running cost of the equipment is also effectively reduced, and competitive power of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of dust and waste gas treatment of mixing plants, in particular to an integrated environmental protection dust removal system suitable for mixing plants and its control system and control method. Background technique [0002] Environmental protection is to coordinate the relationship between human beings and the natural environment, protect the living environment of human beings, and ensure sustainable economic and social development. Protecting the ecological environment is a common challenge and responsibility faced by all mankind. The Fifth Plenary Session of the Eighteenth Central Committee of the Communist Party of China proposed: increase environmental governance, focus on improving environmental quality, and implement the most stringent environmental protection system. [0003] The asphalt mixing plant is the equipment for producing asphalt concrete. During the production process, not only dust is ge...

Problems solved by technology

[0004] The traditional treatment methods of asphalt fume mainly include combustion method, electric capture method, and absorption purification method. The combustion method has high requirements on the concentration, combustion temperature and time of asphalt fume, and requires a special burner, which requires a large investment in equipment and high operating costs. , but also has a great safety hazard; the electric capture method has high requirements on the smoke temperature, which is not conducive to energy saving, and because the asphalt is flammable, this method is not suitable for the purification of the mixed gas of carbon dust and asphalt smoke; the adsorption method requires the adsorption material to have Large adsorption capacity, and the purification efficiency is not high, and there are secondary pollution
