Automatic drainage system used for chemical enterprises

Abstract

The invention relates to a drainage system and discloses an automatic drainage system used for chemical enterprises. The automatic drainage system comprises inlet ditches, a drainage main channel and a drainage ditch, wherein the inlet ditches, the drainage main channel and the drainage ditch are arranged in sequence in the drainage direction; one side of the drainage main channel is provided with a collecting ditch; the collecting ditch is connected with a collecting sump; a concentration detector is arranged in the drainage main channel; the water inlet of the drainage ditch and the water inlet of the collecting ditch are respectively provided with a first shutter and a second shutter; and a first automatic lifting device and a second automatic lifting device are respectively arranged above the first shutter and the second shutter. The automatic drainage system used for the chemical enterprises is simple in structure; the adopted drainage main channel can be used for holding a great amount of drained water when emergent events occur; water reaching the standard and sewage and waste water which do not reach the standard are respectively discharged through the drainage ditch and the collecting ditch, therefore, the water reaching the standard is prevented from being polluted; the drainage ditch and the collecting ditch are respectively opened and closed through the first shutter and the second shutter, therefore, the operation is easy; the ditches cannot be easily blocked, and the shutters are convenient in installation and maintenance and are lower in cost.

Description

technical field [0001] The invention relates to a drainage system, in particular to an automatic drainage system used in chemical enterprises. Background technique [0002] At present, the sewage of general chemical enterprises is transported by pumps or directly through pipelines to the sewage treatment plant in the factory area for treatment. After the water quality meets the existing discharge standards, it enters the municipal sewage treatment plant or is discharged into the water body. [0003] In the existing drainage system, large and medium-sized chemical plants generally use drainage ditches, and small chemical plants generally use drainage pipes, and the main way of drainage is gravity flow drainage. Under normal circumstances, the amount of sewage in the factory area is very small (most of the water has been recycled), but after the accident, the amount of sewage and wastewater increased. When an accident occurs, the sewage and wastewater enter the outdoor rainwa...
