An analytical liquid waste liquid recovery device

technical field

The utility model relates to the field of waste water recovery in petrochemical enterprises, in particular to an analytical liquid waste liquid recovery device.

Background technique

Petrochemical wastewater refers to wastewater discharged from petrochemical plants. The waste water has a large amount of water, in addition to production waste water, there are also cooling water and other water; the components of the waste water are complex, due to the variety of petrochemical products, the reaction process and unit operations are complex, and the nature of the waste water is complex and changeable; the organic matter in the waste water, especially hydrocarbons Class and its derivatives are high in content, and contain a variety of heavy metals. Petrochemical wastewater has many sources and different components, and is closely related to the production process, so it is difficult to determine the quality and quantity of wastewater.

At present, all the excess liquids in the petrochemical industry during analysis, as well as uncontaminated products in the maintenance process, go directly to the sewage treatment station, which is a large part of the waste of wastewater treatment costs, or is a more special toxic. The waste water and liquid waste are directly discharged to general sewage treatment plants, which brings potential risks to the environment and workers, and increases the difficulty of sewage treatment and increases the production and maintenance costs of enterprises.

Preferably, a throttle valve is provided at the front end of the water inlet of the storage tank.

Compared with the prior art, the beneficial effects of the present utility model are as follows:

By adopting the technical scheme of the utility model, the analysis liquid waste liquid is pre-collected by the collection tank, the vent valve is closed, the inlet valve is opened, the waste liquid enters the collection tank from the waste liquid funnel through the inlet valve, and after the collection is completed, the inlet valve is closed , the pressure in the collection tank is stable. At this time, the nitrogen gas pump is turned on, and the nitrogen gas pump pumps out nitrogen to pressurize the inside of the collection tank. When the pressure increases to 1-2 barg, the air pressure in the collection tank will press the waste liquid from the collection tank into the inside of the storage tank. After the waste liquid is stored, open the empty valve, empty the collection tank, and return to normal air pressure; the utility model can effectively collect the analysis liquid waste liquid, and set up a collection tank for transitional collection and a storage tank for final storage or transfer. The waste water that cannot be directly discharged can be collected in a centralized manner, and the treatment can be planned separately to reduce cost waste and improve purification efficiency.
