Description

A device for automatic separation of water and organic solvents

technical field

The utility model relates to the technical field of liquid separation, in particular to a device for automatic separation of water and organic solvents.

Background technique

In industrial production, the wastewater produced generally contains more organic solvents, and direct discharge will cause greater pollution to the environment. Due to the different specific gravity of general organic solvents and water, different height discharge outlets are generally used for separation. However, most of the separation is manual operation, which is not easy to control, and it is easy to cause poor separation effect, resulting in the need for multiple separation and purification, heavy workload, high processing cost and low separation efficiency.

In the prior art, patent document CN102210944A discloses a solvent recovery and separation device, which is provided with a sealed container which is divided into four solution chambers: an oil storage chamber, a buffer chamber, a water storage chamber and a water outlet chamber. The buffer room is equipped with a mixed solution inlet, and the oil storage room is equipped with an organic solvent outlet and a slag discharge port; the oil storage room, buffer room, and water storage room are provided with a drain port, and the water outlet room is provided with a water outlet; the organic solvent outlet is provided with a gear oil pump, and the oil storage room The top is equipped with a magnetic float level switch, the water storage room and the top of the buffer room are equipped with an exhaust port; A water passing board is provided, and water enters the water outlet chamber through the upper part of the water passing board. The top surface of the water flow plate separating the water storage chamber from the buffer chamber is lower than the top surface of the organic solvent flow plate between the buffer chamber and the oil storage chamber. Utilizing the difference in density between the organic solvent and water and the height difference between the water flow plate and the top surface of the organic solvent flow plate, the organic solvent and water are automatically stratified from the buffer chamber into the oil storage chamber and the water storage chamber. Water is automatically pumped back into the system for recycling. The solvent is automatically pumped to the solvent storage tank by the oil pump. However, this device has the problems of complex structure and difficult cleaning, and is not suitable for the continuous separation of slow separation of water and organic solvent mixtures.

Therefore, there is an urgent need to develop a device with a simple structure and suitable for continuous separation of water and organic solvents.

The wastewater sinks to form an interface, and after separation, the organic solvent overflows from the overflow port 3 of the upper liquid; with the continuous injection of the mixture of wastewater organic solvents, the wastewater liquid level gradually rises, pushing the interface float level gauge 6 to float. The ball rises, and when the waste water level reaches 700mm, the floating ball of the interface float level gauge 6 reaches 700mm at the same time, the liquid level transmitter 7 outputs a signal, and the valve 5 on the bottom discharge port 4 of the lower liquid is opened to discharge the waste water When the waste water level is discharged to 300mm, the floating ball of the interface float level gauge 6 reaches 800mm at the same time, the liquid level transmitter 7 outputs a signal, and the valve 5 on the lower liquid discharge port 4 is closed. The valve is a solenoid valve.

The liquid level transmitter and the solenoid valve are connected in a circuit loop, and the trigger signal output by the liquid level transmitter triggers the solenoid valve to open or close.
