Description

Technical Field

[0001] The utility model relates to the technical field of initial rainwater collection in factory areas, in particular to an automatic initial rainwater collection device. Background Art

[0002] According to the "Environmental Protection Engineering Design Standard for Chemical Construction Projects" (GB / T 50483-2019), the definition of "initial polluted rainwater" is "the rainwater generated in the initial stage of rainfall in the polluted area should be taken as the rainfall of 15min to 30min in the initial stage of rainfall, or the rainfall of 20mm to 30mm thickness in the initial stage of rainfall. "Initial rainwater", as the name suggests, is rainwater in the initial stage of rainfall. In the initial stage of rainfall, rainwater dissolves pollutants in the air. After falling to the ground, it washes the ground, causing the initial rainwater to contain a large amount of pollutants, which needs to be collected separately from the later clean rainwater. In the waste incineration plant, there is no water inlet control valve at the entrance of the initial rainwater collection pool, resulting in heavy rainfall during the rainy period, and rainwater in the middle and late stages will also flow into the initial rainwater collection pool. Utility Model Content

[0003] The utility model aims to solve the problem of standardized collection of initial rainwater and reduce the investment in sewage treatment costs.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Further improvements are: the control module includes a PLC controller, a display screen, a relay, a reminder module and a wireless communication module, the rain sensor, the flow meter, and the liquid level sensor are electrically connected to the controller, the controller is electrically connected to the display screen, the relay and the wireless communication module, and the relay is electrically connected to the reminder module and the solenoid valve.
