Description

Technical Field

[0001] The utility model belongs to the technical field of liquid separation and recovery devices, and in particular relates to a liquid separation and recovery device for organic cleaning waste liquid. Background Art

[0002] In the regulations for testing organic matter projects, the standards generally use toluene as the extraction solvent. Generally, after the test is completed, the remaining extract will be poured directly into the organic waste liquid barrel. The instrument needs to be added with the extraction solvent (toluene) again for ultrasonic cleaning, and the waste liquid after cleaning will also be poured into the organic waste liquid barrel. After multiple cleanings, water (tap water) will be used to rinse the surface and interior of the instrument again. At this time, the cleaning waste liquid will not be directly discharged into the sewer pipe, but will flow into the waste liquid temporary storage for collection. Since the main components of the cleaning waste liquid are toluene and water, but because the organic phase (toluene) and the inorganic phase (water) need to be treated separately during the waste liquid treatment process, a liquid separation and recovery device needs to be designed.

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0023] like Figure 1 As shown, an organic cleaning waste liquid separation and recovery device in one embodiment of the present invention includes a waste liquid temporary reservoir 12, with a first delivery pipe 11 and a second delivery pipe 13 fixedly connected to the upper and lower ends of the waste liquid temporary reservoir 12. A first and a second liquid dispensing pipe 14 and 15 are fixedly connected to the second delivery pipe 13. A liquid density sensor 21 is disposed within the second delivery pipe 13, a first control valve 22 is disposed within the first liquid dispensing pipe 14, and a second control valve 23 is disposed within the second liquid dispensing pipe 15. The threshold value of the liquid density sensor 21 is 1.0 g / mL.

[0024] The first liquid distributing pipe 14 is fixedly connected to a first liquid discharging pipe 16, and the second liquid distributing pipe 15 is fixedly connected to a second liquid discharging pipe 17. A seventh control valve 51 is provided in the second delivery pipe 13.

[0025] Specifically, the liquid density sensor 21 is electrically connected to the first control valve 22 and the second control valve 23, respectively. The first control valve 22 is located at the connection between the first liquid dispensing pipe 14 and the second delivery pipe 13, and the second control valve 23 is located at the connection between the second liquid dispensing pipe 15 and the second delivery pipe 13. The cleaning waste liquid enters the waste liquid temporary storage 12 through the first delivery pipe 11 for temporary storage. The water and toluene in the cleaning waste liquid have different densities. The toluene phase has a lower density of 0.872g / mL and is located in the upper layer. The water relative density is higher, and tap water is slightly higher than 1.0g / mL and is located in the lower layer.

[0026] Ginseng Figure 3As shown, the density of water or toluene can be monitored by a liquid density sensor 21. Specifically, the liquid density sensor 21 includes a measuring tube, a portion of which is excited by an electrical feedback drive system (transmitting sensor) to vibrate and maintain its inherent resonant frequency. Changes in the vibrating mass (due to changes in fluid density) will change the resonant frequency of the receiving sensor.

[0027] The mass of a vibrating tube consists of two components: the mass of the tube itself and the mass of the liquid within it. The mass of the tube itself is determined at the factory, so the mass of the liquid within the tube is determined by the density and volume of the liquid within. Since the tube dimensions and volume are already determined, the density of the liquid within the tube is related to the tube's vibration frequency. This signal is output to a density processing unit via the rear electrical connector.

[0028] The Analytical Flow Technology density processing unit uses an algorithm that combines temperature (integrated into the meter), pressure (via an external pressure transmitter with a 4-20mA output), viscosity (via an external viscosity transmitter with a 4-20mA output), and frequency offset to determine the density of the fluid being measured.

[0029] After the waste liquid in the waste liquid temporary reservoir 12 has been allowed to stand for a period of time and has been stratified, the seventh control valve 51 is opened, and the waste liquid in the waste liquid temporary reservoir 12 passes through the liquid density sensor 21 in the second delivery pipe 13. Since the bottom layer is water, it will first flow through the liquid density sensor 21. Since the density of water is slightly higher than 1.0 g / mL, when it is higher than this value, the liquid density sensor 21 transmits a control signal to the first control valve 22 and the second control valve 23. The first control valve 22 opens and the second control valve 23 closes, and the water flows out along the first liquid separation pipe 14 and the first liquid discharge pipe 16. When it is lower than this value, the first control valve 22 closes and the second control valve 23 opens, and the toluene phase flows out along the second liquid separation pipe 15 and the second liquid discharge pipe 17, thereby achieving the separation of water and toluene.

[0030] Ginseng Figure 2 As shown, a protective cover 61 is provided on one side of the waste liquid storage container 12, an observation window 62 is provided in the protective cover 61, and a plurality of fixing bolts 63 are fixedly connected between the protective cover 61 and the waste liquid storage container 12. It is convenient to open the protective cover 61 to clean the inner wall of the waste liquid storage container 12 to prevent it from being eroded by the waste liquid for a long time and causing damage. The observation window 62 is convenient for observing the temporary storage of the waste liquid in the waste liquid storage container 12 and the stratification of water and toluene in the waste liquid. Preferably, a sealing gasket is provided between the protective cover 61 and the waste liquid storage container 12 to prevent the waste liquid in the waste liquid storage container 12 from leaking.

[0031] A separation box 31 is provided on the second liquid discharge pipe 17, and a heating device 34 is installed in the separation box 31. A bleed valve 35 is provided on the separation box 31. A third control valve 32 and a fourth control valve 33 are installed in the second liquid discharge pipe 17, and the third control valve 32 and the fourth control valve 33 are located on the upper and lower sides of the separation box 31, respectively.

[0032] Specifically, when toluene passes through the liquid density sensor 21, the first control valve 22 closes and the second control valve 23 opens. However, a portion of water in front of the toluene does not have time to flow out through the first liquid separator 14. Since the first control valve 22 is closed, this portion of water can only flow along the second liquid separator 15 and the second liquid discharge pipe 17, and the toluene at the back follows the flow. The fourth control valve 33 is closed, so that the water and a portion of the toluene at the back will flow into the separation box 31. The third control valve 32 is closed, and the heating device 34 is started to heat the water and toluene in the separation box 31. Since the boiling point of water is lower than that of toluene, the water will evaporate first. The evaporated gas is discharged through the air release valve 35, and then the third control valve 32 and the fourth control valve 33 are opened, and the toluene is discharged through the second liquid discharge pipe 17.

[0033] A first recovery pipe 41 is fixedly connected between the waste liquid temporary reservoir 12 and the first liquid dispensing pipe 14. A fifth control valve 43 is provided in the first recovery pipe 41. A second recovery pipe 42 is fixedly connected between the waste liquid temporary reservoir 12 and the second liquid dispensing pipe 15. A sixth control valve 44 is provided in the second recovery pipe 42.

[0034] Specifically, Figure 4 As shown, open the fifth control valve 43, the water in the lower floor of the waste liquid storage 12 will be discharged directly through the first recovery pipe 41, the first liquid dispensing pipe 14 and the first liquid discharge pipe 16. When the water is about to be discharged, close the fifth control valve 43. Open the sixth control valve 44. The remaining water is first discharged into the separation box 31 through the second recovery pipe 42, the second liquid dispensing pipe 15 and the second liquid discharge pipe 17, and the toluene at the back follows. By closing the fourth control valve 33 and the third control valve 32, the waste liquid in the separation box 31 is separated from the outside world, and then the water is evaporated. Then, open the third control valve 32 and the fourth control valve 33 to discharge the toluene at the back. The waste liquid in the waste liquid storage 12 can also be separated without passing through the liquid density sensor 21 in the second delivery pipe 13.

[0035] A temperature sensor is provided in the separation box 31. It is convenient to monitor the temperature of the waste liquid in the separation box 31 and to evaporate the water.

[0036] When using, refer to Figure 1As shown, the cleaning waste liquid containing water and toluene is discharged into the waste liquid temporary storage 12 through the first delivery pipe 11 for temporary storage. After a period of temporary storage, due to the difference in density, the water is located in the lower layer and the toluene is located in the upper layer. The seventh control valve 51 is opened, and the water in the lower layer of the waste liquid temporary storage 12 will first pass through the liquid density sensor 21. The liquid density sensor 21 detects that the density of the water is higher than 1. At this time, the first control valve 22 is opened, the second control valve 23 is closed, and the water is discharged through the first liquid separation pipe 14 and the first drainage pipe 16. When the toluene behind the water passes through the liquid density sensor 21, the liquid density sensor 21 detects that the density is lower than 1. At this time, the first control valve 22 is closed, the second control valve 23 is opened, and the toluene is discharged through the second liquid separation pipe 15 and the second drainage pipe 17, thereby achieving the purpose of separating water and toluene in the waste liquid.

[0037] Compared with the prior art, the organic cleaning waste liquid separation and recovery device of the present invention can easily separate the organic phase (toluene) and the inorganic phase (water) in the cleaning waste liquid, thereby facilitating subsequent waste liquid treatment.
