Description

Technical Field

[0001] The utility model relates to the technical field of ethylene glycol recovery, in particular to an ethylene glycol recovery device. Background Art

[0002] Ethylene glycol is a colorless, odorless and sweet liquid. At present, in chemical production, ethylene glycol, water and other wastes are generated in the processes of amide production, ether aldehyde production, bromination and cyclization reaction. Ethylene glycol has high recycling value. Existing manufacturers generally set up ethylene glycol recovery and treatment devices in factories to treat waste ethylene glycol, extract ethylene glycol with higher purity, and then store it in a recovery tank.

[0003] However, there are still deficiencies in the existing ethylene glycol recovery tank during use. After being treated, ethylene glycol is injected into the storage tank for storage. The treated ethylene glycol may contain fine impurities. After too much ethylene glycol is added to the same tank, a large amount of impurities are likely to accumulate at the bottom of the inner wall of the tank. As the storage time prolongs, the accumulated impurities are more and more difficult to clean up. And when ethylene glycol is taken out from the storage tank for use again, the impurities are mixed in the ethylene glycol again. This leads to that ethylene glycol needs to be treated again before use, which takes a lot of time and is not conducive to use. Summary of the Utility Model

[0004] The utility model provides an ethylene glycol recovery device to solve the problem that the existing recovery and storage tank has no structure for filtering impurities.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides as Figures 1-6An ethylene glycol recovery device shown in the figure includes a tank body 1. A recovery pipeline is provided at the top of the tank body 1, and a filtering device 2 is provided at the top of the recovery pipeline. The filtering device 2 includes an installation box 23. A channel 28 is opened inside the installation box 23. A plurality of first slots 26 are opened on the front surface of the installation box 23. A second slot 27 is further opened on one side of each first slot 26. A filtering component 25 is arranged in each first slot 26. The filtering component 25 includes an activated carbon filter element 251. One end of the activated carbon filter element 251 is provided with a downwardly protruding block, and a dirt collecting groove 252 is opened at the top of the block. A front baffle 253 is fixed to the end of the activated carbon filter element 251. A round hole is opened on the front surface of the front baffle 253. One side of the bottom of the dirt collecting groove 252 is provided with a sealing rod 255. The front end of the sealing rod 255 penetrates through the round hole and extends to the front surface of the front baffle 253. Specifically, internal threads can be provided on the inner wall of the round hole, and external threads can be provided on the outer wall of the sealing rod 255. By screwing the sealing rod 255 into the round hole, the bottom end of the dirt collecting groove 252 is sealed by the sealing rod 255 to ensure that impurities will not overflow.

[0026] Specifically, during the process of inserting the activated carbon filter element 251, the activated carbon filter element 251 is inserted horizontally from the front surface of the first slot 26. After the activated carbon filter element 251 is completely inserted into the first slot 26, the rear surface of the front baffle 253 is closely attached to the front surface of the installation box 23. After the first slot 26 is filled with the activated carbon filter element 251, the downwardly protruding block at one end of the activated carbon filter element 251 fills the second slot 27.

[0027] In this embodiment, it should be noted that ethylene glycol is input into the interior of the installation box 23 through the feed pipe 21, flows downward through the channel 28, and is filtered by the activated carbon filter element 251 inserted in the first slot 26. Among them, the activated carbon filter element 251 filters the impurities mixed in the ethylene glycol. The impurities accumulate on the top of the activated carbon filter element 251, and the impurities flow along the top surface of the activated carbon filter element 251 towards the dirt collecting groove 252 due to their own gravity and accumulate more and more. By removing the sealing rod 255, the impurities in the dirt collecting groove 252 can be extracted with a syringe.

[0028] For the activated carbon filter element 251 inside the installation box 23, from top to bottom, the pores of the activated carbon filter element 251 become smaller and smaller, so as to filter impurities of different sizes and achieve the purpose of multi-stage filtration.

[0029] Such as Figures 2-4 and Figure 6As shown in the figure, two limiting rods 24 are symmetrically arranged on the front surface of the installation box 23. Card slots 241 are formed on the front surfaces of the two limiting rods 24. Screw holes are also formed on one side wall of the limiting rod 24 located at the card slot 241. Clamping blocks 254 are arranged on both sides of the front baffle 253. The end of the clamping block 254 can be inserted into the card slot 241, and threaded holes corresponding to the screw holes are formed on the side wall of the clamping block 254. After the activated carbon filter element 251 is completely inserted into the first slot 26 of the installation box 23, the clamping block 254 is also automatically inserted into the card slot 241 on the front surface of the limiting rod 24, and a bolt can penetrate the limiting rod 24 from the side of the limiting rod 24 and press the clamping block 254 tightly.

[0030] As Figure 1 shown in the figure, a discharge pipe 9 is also arranged on one side of the bottom end of the tank body 1. A discharge valve is arranged on the discharge pipe 9. A support frame 8 is also arranged on one side of the tank body 1. Specifically, the discharge valve on the discharge pipe 9 is opened, and an external drainage pipe needs to be connected to the end of the discharge pipe 9. Ethylene glycol automatically flows to the outside through the discharge pipe 9 and flows to an external container through the drainage pipe, thereby completing the material taking.

[0031] As Figure 4 and Figure 5 shown in the figure, the top of the activated carbon filter element 251 is an inclined surface. Two sealing strips 256 are arranged on the rear surface of the front baffle 253. The two sealing strips 256 respectively correspond to the top edge and the bottom edge of the front surface of the activated carbon filter element 251. Specifically, after the activated carbon filter element 251 is completely inserted into the first slot 26 of the installation box 23, the rear surface of the front baffle 253 fits with the front surface of the installation box 23, and the sealing strip 256 blocks the edge of the front of the first slot 26, thereby ensuring that ethylene glycol will not overflow.

[0032] As Figure 1 shown in the figure, a titanium alloy temperature measuring rod 6 is arranged on the top of the tank body 1. The top end of the titanium alloy temperature measuring rod 6 is connected with a data cable 5, and the extending end of the data cable 5 is connected with a temperature monitor 7. The titanium alloy temperature measuring rod 6 extends into the tank body 1. By contacting the ethylene glycol stored in the tank body 1 through the titanium alloy temperature measuring rod 6, the temperature of the ethylene glycol is detected. The real-time temperature of the ethylene glycol can be seen on the temperature monitor 7. The temperature of the storage environment where the tank body 1 is located can be lowered or raised according to the temperature of the ethylene glycol. The temperature monitor 7 and the titanium alloy temperature measuring rod 6 are already existing technologies and will not be elaborated here.

[0033] As Figure 1As shown, an exhaust pipe 4 is provided on one side of the top end of the tank body 1, and a valve 3 is provided on the exhaust pipe 4; specifically, the end of the exhaust pipe 4 can be connected to an external air extraction device, and the external air extraction device can extract the air inside the tank body 1, so that the tank body 1 can exhaust air. Regularly exhausting air from ethylene glycol is beneficial to the storage of ethylene glycol, can reduce health risks, improve storage safety, and thus protect the environment.

[0034] As Figures 1-3 As shown, a feed pipe 21 is provided at the top end of the installation box 23, and a discharge pipe 22 is provided at the bottom end of the installation box 23. The discharge pipe 22 is flange-connected to the recovery pipeline at the top end of the tank body 1; specifically, the feed pipe 21 at the top end of the installation box 23 can be flange-connected to an external ethylene glycol delivery pipeline. Flange connection is beneficial for sealing and can prevent ethylene glycol from leaking.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
