The central processing unit of work, can ensure exhausting effect simultaneously, as far as possible reduce negative pressure generator exhausting power, thus
Realize energy-saving and environment-friendly purpose.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is a kind of structural schematic diagram of copper smelting-furnace exhaust-gas treatment wind pressure automatic regulating system of the present invention.
Specific embodiment
Referring to Fig.1, Fig. 1 is the structural schematic diagram of a specific embodiment of the invention.
As shown in Figure 1, a kind of copper smelting-furnace exhaust-gas treatment wind pressure automatic regulating system, including a negative pressure generator 1, one
The negative pressure transportation main pipeline 2 of a connection negative pressure generator 1, the multiple exhausting for being connected in parallel the negative pressure transportation main pipeline 2
It is vented the central processing unit of station, the variable-frequency motor 3 that the driving negative pressure generator 1 works and the control variable-frequency motor 3
4, each exhausting exhaust station includes electromagnetism aperture valve 5 for controlling exhausting air-flow size and for detecting wind
The air monitoring device 6 of fast size, the electromagnetism aperture valve 5 and the air monitoring device 6 connect with 4 signal of central processing unit
It connects.
When work, the air monitoring device 6 detection of the exhausting exhaust station each first obtains air speed data, and passes
The central processing unit 4 is transported to, the central processing unit 4 will test the wind speed of acquisition compared with setting value, set when wind speed is less than
The electromagnetism aperture valve 5 that the corresponding exhausting exhaust station is then controlled when definite value increases aperture, when wind speed is greater than the set value
The electromagnetism aperture valve 5 for then controlling the corresponding exhausting exhaust station reduces aperture.
When the electromagnetism aperture valve 5 of some described exhausting exhaust station reaches maximum opening, and exhausting row
When the corresponding detection of the air monitoring device 6 acquisition wind speed of gas station is still less than setting value, then the central processing unit 4 issues
Signal controls the variable-frequency motor 3 and increases output power, to make the negative pressure exhausting ability of the negative pressure generator 1 improve, directly
