Description

Technical Field

[0002] In the deodorization system of sewage treatment plants, negative pressure suction is often used, that is, the induced draft fan is used to suck part of the odor above the sewage pool and then discharge it into the chimney at high speed after purification. According to environmental protection regulations, the minimum point source emission height is 15m, so the minimum chimney height is 15m. The qualified flue gas is discharged into the air through the chimney, and ammonia, hydrogen sulfide and other detection facilities and lighting facilities are required in the air. These facilities require electricity, and introducing cables from the outside is not only troublesome, but also a waste of resources. The designed emission speed of flue gas in the chimney is generally 10-15m / s, and these kinetic energy is discharged to high altitudes through the chimney, resulting in huge waste.

[0007] Furthermore, an induced draft fan is arranged on one side of the chimney body, and a chimney oblique air inlet pipe is arranged between the induced draft fan and the chimney body.

[0008] Furthermore, the wind power generation system includes an impeller, a generator drivingly connected to the impeller, and a power storage unit connected to an output end of the generator.

[0009] Furthermore, the ratio of the impeller diameter to the chimney diameter is 1:3 to 1:5.

[0030] When the smoke speed of the induced draft fan entering the chimney is lower than 5m / s, the impeller can still rotate rapidly. After adding the induced draft fan, the normal design wind speed of the induced draft fan entering the chimney is 10-15m / s, and the impeller can achieve high-speed rotation.

The control device can be various PLCs, single-chip microcomputers, etc. When the speed of the smoke entering the chimney is lower than a predetermined value, the induced draft fan is turned on. The predetermined value is set according to needs, for example, 5m / s.

[0039] Example 7
