Abstract

The invention discloses a desulfurization device suitable for a thermal power plant, and belongs to the field of exhaust gas desulfurization treatment. The desulfurization device suitable for the thermal power plant comprises a treatment box, two sides of the lower end of the outer surface of the treatment box are fixedly connected with mounting plates, a cover plate is fixedly mounted at the opening of the upper surface of the treatment box, the lower surface of the cover plate is fixedly connected with a connecting plate through a water inlet tube, an avoidance through hole is arranged in the inner center of the connecting plate, an annular cavity is arranged in the connecting plate, the lower surface of the annular cavity is fixedly connected with spray heads, a motor is fixedly mounted at a center of the upper surface of the cover plate, the lower surface of the motor is fixedly connected with a rotating shaft, two sides of the outer surface of the rotating shaft are fixedly connected with supporting rods, a connecting rod is arranged at the end part of every supporting rod, and the other ends of the connecting rods are fixedly connected with scraping plates. The device can greatly improve the convenience and stability of use, and can ensure the efficiency and effect of treatment.

Description

Technical field [0001] The invention relates to the field of exhaust gas desulfurization treatment, and more specifically, to a desulfurization device suitable for thermal power plants. Background technique [0002] During the operation of thermal power plants, a large amount of coal needs to be consumed, which will generate a large amount of exhaust gas, and the coal contains sulfur, which will form products such as sulfur dioxide when reburned, which will cause air pollution and require desulfurization treatment. Emissions are generally treated by contact and reaction with ammonia. [0003] However, when the existing desulfurization device is reused, most of the exhaust gas is directly passed into the ammonia water for neutralization reaction. This not only has a small contact area, but also affects the reaction rate, resulting in a low neutralization treatment rate, and at the same time, the reaction formed crystals will precipitate. It is easy to stick to the intake pipe, whic...

Problems solved by technology

[0003] However, when the existing desulfurization devices are reused, most of them directly pass the waste gas into the ammonia water for neutralization reaction, which not only has a small contact area, but also affects the reaction rate, resulting in a low neutralization treatment rate, and at the same time, the crystals formed by the reaction will be precipitated. It is easy to stick to the intake pipe, not only inconvenient for centralized cleaning and collection, but also easy to block the pipe, which affects the stability of use and is not conducive to desulfurization treatment
