Embodiment Construction

[0021] In recent years, the use of PLC network technology to realize distributed sampling has become a consensus, that is, a set of sampling units is set up near the controlled point, and the state sampling and control output of the controlled point are completed nearby, and the sampling units are connected through an industrial control network to form a The lower computer system of the monitoring system. The network can form a redundant network according to user needs, and can fully meet the needs of on-site sampling technically. The operator station and engineer station with monitoring function use graphical monitoring terminals to complete the centralized monitoring, data analysis, unified scheduling and management of the controlled equipment. For communication between the operation station and the lower computer, an industrial control network can be selected to form a local monitoring system, or a telephone communication line, wireless transmission network, etc. can be sel...

Abstract

The invention belongs to the field of an environment protective control, which particularly relates to an electric dedusting control system and a control method thereof; the invention is essentially applicable to the fields such as the power supply system, cement, metallurgy, nonferrous metals and chemical industries, including a central control system, an upper machine set and a lower machine set; the industrial Ethernet based on the TCP/IP protocol is adopted among upper computers in the upper machine set and between the upper computers and lower computers, the lower machine set is connected with the central control system by a switch software Ethernet, the central control system is taken as a monitoring control terminal to design, alter and debug the operation of the system in the upper computer image monitoring control terminal software; the electric dedusting control method includes a fan control, an evaporation low temperature control, an electric field control, a rapping control, a changing-over station control and a gas cold control. The environment protective control of the invention has high degree of automation, low operation cost, small electric energy consumption, convenient maintenance and management and relatively high dedusting efficiency.

Description

technical field [0001] The invention belongs to the field of environmental protection control, and in particular relates to an electric dust removal control system and a control method thereof, which are mainly used in electric power systems, cement, metallurgy, non-ferrous metals and chemical industries. Background technique [0002] With the continuous strengthening of environmental protection awareness and the continuous improvement of environmental protection requirements, the steel industry is fiercely competitive, effectively improving product quality, output, saving electricity and water resources, and reducing environmental pollution. These links are urgent problems to be solved in the metallurgical industry. Flue gas dust removal has been widely used in the iron and steel industry, usually including gravity, cyclone dust removal, bag dust removal, and electric dust removal. Among them, the electrostatic precipitator has the advantages of high dust removal efficiency...
