Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to an automatic separation tank for toluene and water. Background Art

[0002] A large amount of water will be generated during the toluene oxidation reaction. Because the water generated by the reaction contains a large amount of toluene, if the toluene in the water is not separated cleanly and enters the sewage treatment station for treatment, this will bring great difficulties to sewage treatment and make it difficult to meet the sewage treatment standards.

[0003] The current method for separating and treating the water generated after the toluene oxidation reaction is to put the water generated after the reaction into a tank and manually operate it. The operator opens the water outlet valve at the bottom of the tank to drain the water. When toluene is seen flowing out, the water outlet valve is immediately closed. Due to manual operation, misoperation often occurs, which not only causes certain economic losses to the company, but also poses a safety risk.

[0004] Therefore, a toluene and water automatic separation tank is proposed to solve the above problems. Utility Model Content

[0005] In response to the above technical problems, the utility model provides an automatic toluene and water separation tank, which automatically recovers toluene and discharges water to meet the water inlet index requirements of the sewage treatment station, and the separation process is unmanned, saving labor costs.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The automatic separation tank for toluene and water is characterized in that it includes a tank body, a baffle, an overflow tank, a water inlet tank, a baffle and a drain pipe. A plurality of baffles are arranged at intervals in the inner cavity of the tank body, and two adjacent baffles are staggered. A baffle is arranged at one end of the inner cavity of the tank body. An overflow tank is installed in the tank body between the baffle and the baffle. The bottom of the overflow tank is sleeved on the water inlet tank and the upper notch of the water inlet tank extends into the overflow tank. The notches at both ends of the water inlet tank are open. The lower notch of the water inlet tank is located above the bottom of the tank body. The drain outlet provided on the overflow tank is connected to the drain pipe. The drain pipe passes through the baffle and the side wall of the tank body and extends out.

[0008] The inner cavity of the tank is separated by a baffle to form a toluene storage bin. The discharge port provided on the wall of the toluene storage bin is connected to the discharge pipe.

[0009] The upper end of the trough body is fixedly connected to the upper cover, and a feed port is provided on one end of the upper cover which is located in a direction opposite to the discharge port, and the feed port of the upper cover is connected to the feed pipe.

[0010] Specifically, the height of the upper notch of the water inlet trough is lower than the height of the notch of the overflow trough.

[0011] Specifically, the height of the drain outlet provided on the overflow trough is lower than the height of the upper notch of the water inlet trough.

[0012] Specifically, the height of the baffle is higher than the height of the overflow trough notch.

[0013] Beneficial effects of the utility model:

[0014] The utility model proposes a separation tank for automatically separating toluene and water. Baffles are arranged in an interlaced manner in the tank to increase the residence time of water and toluene in the tank and achieve a better separation effect.

[0015] A feed port is provided at one end of the tank body, and a discharge port and a drain port are provided at the other end of the tank body. Relying on the action of gravity and the residence time in the separation tank, toluene and water are automatically separated in the separation tank, and toluene is automatically recovered.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Example 1

[0026] As shown in the figure, a baffle 6 is provided at one end of the inner cavity of the tank body 1, and the inner wall of the tank body 1 and the baffle 6 form a toluene storage bin 13, and a discharge pipe 11 is connected to the discharge port provided on the bin wall of the toluene storage bin 13. The upper end of the tank body 1 is fixedly connected to the upper cover 2, and a feed port is provided on the end of the upper cover 2 opposite to the discharge port, and the feed port is connected to the feed pipe 21.

[0027] A number of baffles 3 are arranged at intervals in the inner cavity of the trough body 1, and two adjacent baffles 3 are staggered. An overflow trough 4 is installed in the trough body 1 between the baffle 6 and the baffle 3. The two outer ends of the overflow trough 4 are respectively connected to the inner wall of the trough body 1. The bottom of the overflow trough 4 is sleeved on the water inlet trough 5 and the upper end notch of the water inlet trough 5 extends into the overflow trough 4. The notches at both ends of the water inlet trough 5 are open. The lower end notch of the water inlet trough 5 is located above the bottom of the trough body 1. The drain outlet set on the overflow trough 4 is connected to the drain pipe 12. The drain pipe 12 passes through the baffle 6 and the side wall of the trough body 1 and extends out, wherein the upper end notch height of the water inlet trough 5 is lower than the notch height of the overflow trough 4, and the height of the drain outlet set on the overflow trough 4 is lower than the notch height of the upper end notch of the water inlet trough 5, and the height of the baffle is higher than the height of the notch height of the overflow trough 4.

[0028] Example 2

[0029] When using the utility model, the water generated after the oxidation reaction of toluene is transported to the tank body from the feed pipe 21. The baffles 3 arranged at intervals in the inner cavity of the tank body 1 increase the time that toluene and water stay in the tank body 1, thereby enhancing the separation effect of toluene and water.

[0030] Toluene is insoluble in water, and water has a high density. When water is in the tank body 1, it is located in the lower layer, so the water in the lower layer enters the water inlet tank 5 from the lower end slot of the water inlet tank 5. When the water level is higher than the upper end slot of the water inlet tank 5, the water overflows into the overflow tank 4. The height of the upper end slot of the water inlet tank 5 is lower than the height of the slot of the overflow tank 4, and the height of the drain port on the overflow tank 4 is lower than the height of the slot of the water inlet tank 5. The water overflowing into the overflow tank 4 is discharged through the drain pipe 12 at the drain port on the overflow tank 4, so the upper layer of toluene that has been separated out cannot enter the drain port, so that the discharged water enters the sewage treatment station, meeting the water inlet index requirements of the sewage treatment station.

[0031] The toluene separated from the upper layer flows into the toluene storage bin 13 from the upper end of the baffle 6 and is discharged from the discharge port 11. The entire separation process is unmanned, saving labor costs.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
