On-site recovery system for leaking waste liquid

Abstract

The invention discloses an on-site recovery system for leaking waste liquid. The recovery system comprises a control system, a water liquid recovery pipeline assembly, an inert gas pipeline assembly, an inert gas source, a waste liquid recovery device and a waste liquid delivery pipeline assembly, wherein a plurality of recovery chambers are arranged in the waste liquid recovery device. The control system controls valves on pipelines to be opened and closed, so that the waste liquid enters one or more recovery chambers. When the liquid level in one recovery chamber reaches a set value, the waste liquid is collected to the empty recovery chambers. Meanwhile, the recovery chamber reaching the set liquid level is pressurized by inert gas, so that the waste liquid is delivered to set positions through a waste liquid delivery pipeline. According to the recovery system, the traditional mode that liquid is drained through a pump is replaced by the mode that the liquid is drained through pressurization by the inert gas, so that waste liquid leaking caused by fault maintenance of the pump is avoided effectively; moreover, waste gas volatilizing from the waste liquid in the waste liquid recovery device is effectively prevented from making contact with air through the inert gas, so that the danger of explosion is avoided.

Description

technical field [0001] The invention relates to a recovery system for on-site running, emitting, dripping, and leaking waste liquid. Background technique [0002] The media involved in the production process of cyclohexanone mainly include flammable, toxic and volatile organic substances such as cyclohexane, cyclohexanol, cyclohexanone, and cyclohexene. In the recovery of traditional cyclohexanone waste liquid, Each sewage and deluge enters the underground tank through the recovery main pipeline. When the liquid level in the underground tank reaches a certain height, the pump is used to transport the waste liquid in the underground tank to the unit used or the waste liquid treatment place, but the pump is prone to failure. In the maintenance process of the pump, it is inevitable to produce leaks, leaks, irritating odors, pollute the environment, and bring harm to the health of post operators and maintenance personnel. In addition, the environment of the underground tank in ...

During the maintenance process of the pump, it is inevitable to produce leakage, irritating smell, pollute the environment, and bring harm to the health of post operators and maintenance personnel.

In addition, the environment of the underground tank in the traditional method is air, and the gas volatilized with the waste liquid is easy to form an explosive gas, which may cause an explosion
