Abstract
The utility model relates to a smelting flue gas automatic control system which comprises a control unit. An input interface of the control unit receives a blower air volume parameter, an induced draft fan variable frequency parameter and a furnace top negative pressure parameter; and the control unit is connected with an executing unit to implement regulation on the blower air volume parameter, the induced draft fan variable frequency parameter and the furnace top negative pressure parameter. According to the utility model, a blower is subjected to heat exchange by utilizing the PLC (Programmable Logic Controller) control unit; an induced draft fan is electrically controlled; and the blower air volume parameter, the induced draft fan variable frequency parameter, the furnace top negative pressure and the like are all displayed on a computer display. According to the process requirements, specific values are input onto a computer and PLC programming is carried out, so that control on data can be implemented by utilizing the PLC.
Description
Technical field
The utility model relates to the flue gas automatic control system of metal smelt or regeneration melting.
Background technology
In existing metal smelt or the regeneration smelting technology, the front and back parameter generally all adopts Artificial Control, if accident appears in workman's carelessness easily, and cost of labor is high, adopts manpower control, also is unfavorable for reducing production costs.
The utility model content
The utility model provides a kind of flue gas automatic control system at above-mentioned defective, adopts every index of the real-time Monitoring and Controlling technology of computer, and security is good, and is easy to operate, reduces enterprise's production cost.
For this reason, the utility model is taked following technical scheme, a kind of melting flue gas automatic control system, comprise control module, the input interface of described control module receives air blast air quantity parameter, air-introduced machine frequency conversion parameter, furnace roof negative pressure parameter, and described control module connects the performance element realization to the adjusting of air blast air quantity parameter, air-introduced machine frequency conversion parameter, furnace roof negative pressure parameter.
Described control module connects display unit.
Described control module is PLC.
The utility model utilizes the PLC control module that air blast heat exchange air-introduced machine is adopted electronic control, and parameters such as air blast air quantity, air-introduced machine frequency conversion, furnace roof negative pressure are all shown at computer display screen.According to technological requirement, import concrete numerical value on computers, carry out the PLC programming, just can utilize the PLC realization to the control of these data.
Adopt this automatic control system to realize that the furnace roof negative pressure regulates automatically, furnace roof is no longer smoldered.This controls automatically also that system has reduced the instrument working strength of workers, has reduced artificial hysteresis quality accident.This automatic control system has reduced unnecessary cold wind and has sucked, and the working of a furnace is better.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is control flow chart of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of melting flue gas automatic control system as depicted in figs. 1 and 2, comprise control module, the input interface of control module receives air blast air quantity parameter, air-introduced machine frequency conversion parameter, furnace roof negative pressure parameter, control module connects the performance element realization to the adjusting of air blast air quantity parameter, air-introduced machine frequency conversion parameter, furnace roof negative pressure parameter, and control module also connects display unit.Control module is preferably PLC.
Native system is the PLC automatic control flow chart, mainly is to utilize PLC realization smelting furnace flue gas to control automatically.This system blower air quantity must meet the smelting technology requirement, and the top negative pressure must meet the smelting technology requirement, and system also can switch to manual Artificial Control as required.
Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
