AI Technical Summary

Technical Problem

Due to the lack of tight sealing of pipelines or equipment and equipment in the thermal power plant, acidic substances such as CO2 are leaked. The initial content of pollutants in rainwater is high, and direct emissions will harm the environment.

Method used

A rainwater storage and discharge device is designed, including a reservoir and an overflow weir. The reservoir is divided into a first water storage part and a second water storage part through the overflow weir. The initial rainwater is discharged into the sewage tank through the sewage pipe, and the middle and late rainwater enters the second water storage part through the overflow weir and is discharged into the natural environment.

Benefits of technology

The collection and treatment of rainwater in the early stages of the carbon capture process area has been realized, which has reduced the pollution to the environment, ensured the normal emission of rainwater in the middle and late stages, and reduced the amount of rainwater that needs to be collected and purified in the carbon capture process area, which has significant economic benefits, environmental protection benefits and social benefits.

Abstract

The utility model discloses a rainwater storage and drainage device for carbon capture of a thermal power plant, the rainwater storage and drainage device comprises a reservoir and an overflow weir arranged in the reservoir, and the overflow weir divides the reservoir into a first water storage part and a second water storage part; wherein the first water storage part is communicated with a rainwater inlet pipe and used for pre-storing rainwater in a carbon capture area, the first water storage part is further communicated with a blow-off pipe, and the blow-off pipe is used for discharging rainwater in the initial stage of carbon capture into a sewage pool; when the rainwater in the first water storage part is higher than the overflow weir, the rainwater enters the second water storage part from the first water storage part; the second water storage part is used for later storage of rainwater in the carbon capture area and is provided with a rainwater discharge pipe, and the rainwater discharge pipe is used for discharging rainwater in the later period of the carbon capture area into the natural environment. Rainwater is discharged in a classified mode according to the carbon capture stage, the amount of rainwater collected in a carbon capture process area is reduced, and pollution to the environment is reduced.
