Description
Technical Field
The utility model relates to the field of rain and sewage diversion of petrochemical storage tanks, in particular to an automatic rain and sewage diversion switching system for a petrochemical storage tank area.
Background
Petrochemical storage tanks have the risk of accidents such as leakage and explosion due to the storage of large amounts of substances such as oils, asphalt and the like. In case of accident, the accident will not only harm the environment and surrounding personnel, but also seriously destroy the local ecological system and water resource. Therefore, effective measures are required to cope with these accidents.
Rain and soil switching is an effective countermeasure. The method mainly comprises the steps of arranging two sets of drainage systems in a petrochemical storage tank area, wherein one set is a rainwater system and the other set is a sewage system. Under normal conditions, the rainwater system is mainly responsible for collecting and discharging rainwater, while the sewage system is responsible for collecting and discharging sewage. However, in the case of an accident, leakage or explosion of various oils and asphalt or the like may occur, resulting in the entry of contaminants into the rainwater system. At the moment, the rainwater system can be rapidly switched to the sewage system through rainwater and sewage switching, so that pollutants are prevented from being directly discharged into the environment; meanwhile, the sewage system can be discharged after being treated, so that the pollution to the environment is reduced.
At present, the switching mode of tank field rain and sewage diversion mainly comprises the following two modes:
One is manual switching, which may have the risk of casualties or untimely operation leading to contaminants entering the rainwater pipeline in the sudden accident;
An automatic switching mode in the prior art mainly discharges initial rainwater into a sewage pipeline, and the discharge time of the initial rainwater is generally 15 minutes, namely: after 15 minutes, the device is automatically switched to drain the rainwater pipeline.

When emergency is met, if sewage enters a rainwater pipe network, a switching pump can be started manually, polluted rainwater in a rainwater main discharge port is pumped to the sewage main discharge port, and the polluted rainwater is sent to a sewage treatment plant.
In summary, the existing rain and sewage diversion system for the storage tank area cannot realize accurate automatic switching, and particularly cannot respond in time under the condition of sudden accidents such as leakage and the like, and manual switching is needed. Therefore, the application provides an automatic rain and sewage diversion switching system for petrochemical storage tank areas, which solves the problem.
