Smoke dust removing control system

Abstract

A smoke dust removing control system comprises a collecting device and a control device which are connected with each other. The collecting device is arranged in a converter. The control device comprises a control module and a differential pressure meter. The control module is a PLC central processor. The differential pressure meter and the PLC central processor are connected with each other. The prestored numerical value is set in the PLC central processor. The differential pressure meter transmits the numerical value in the converter to the PLC central processor. The control system is internally provided with the differential pressure meter, data can be transmitted to the differential pressure meter through the collecting device in the converter, the numerical value obtained by the differential pressure meter is compared with the prestored numerical value in the PLC central processor, the contrast numerical value is obtained so that a throat opening of the converter can be controlled to be opened and closed, and precise opening and closing control can be conducted on the converter.

Description

technical field [0001] The invention relates to a control system, in particular to a smoke and dust removal control system. Background technique [0002] At present, the treatment of flue gas in the iron and steel industry is in a state of manual control, and it is impossible to monitor and track the flue gas generated by the converter. The reason why the high-pressure fan on site cannot be adjusted in speed is that the fan has been in a high-speed state since the furnace was opened, which is also very important for energy. Waste, even in this way, the effect of flue gas emission is not ideal, polluting the surrounding environment, and also causing high energy consumption of high-pressure fans, increasing the energy consumption of iron and steel production enterprises, and making iron and steel production enterprises higher production costs. The treatment cannot be monitored anytime and anywhere, and the dust content in the flue gas is high, which will also have a certain im...

[0002] At present, the treatment of flue gas in the iron and steel industry is in a state of manual control, and it is impossible to monitor and track the flue gas generated by the converter. The reason why the high-pressure fan on site cannot be adjusted in speed is that the fan has been in a high-speed state since the furnace was opened, which has a great impact on energy. Waste, even the effect of dealing with flue gas emission in this way is not ideal, pollutes the surrounding environment, also causes high energy consumption of high-pressure fans, increases the energy consumption of steel production enterprises, and makes the production cost of steel production enterprises higher. The treatment cannot be monitored anytime and anywhere. The dust content in the flue gas is high, which will also have a certain impact on the body of the operator, resulting in poor control system control of the converter, and a large amount of smoke and dust in the converter.
