Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figure 2 , the present application provides a kind of electrolytic copper waste gas waste liquid separation type recovery equipment including electrolytic device 01 for electrolytic copper;Electrolytic device 01 top is provided with for discharging waste gas gas outlet 04 and for discharging waste liquid water outlet 05;Setting in electrolytic device 01 one side, for purifying waste liquid produced in electrolytic device 01 waste liquid treatment device 02;Waste liquid treatment device 02 has for controlling waste liquid inflow and outflow water inlet 06 and drain 07, also has setting in water inlet 06 and drain 07 microbial plate 08;Microbial plate 08 is close to the side of water inlet and is equipped with waste water filter 09;Setting in waste liquid treatment device 02 upper, for processing waste gas produced in electrolytic device 01 waste gas treatment device 03;Waste gas treatment device 03 includes: for inhaling and discharging waste gas air inlet 11 and exhaust port 12;In the lower 11 of air inlet, for filtering harmful particulate matter in gas waste gas filter 13;In the lower waste gas filter 13, for absorbing and processing harmful gas purification component 14. Among them, waste liquid treatment device 02 and waste gas treatment device 03 are all installed with heat collecting tube 16 for collecting waste liquid waste gas residual heat, and the heat collecting tube in waste gas treatment device 03 is between waste gas filter 13 and purification component 14.

[0023] It can be understood that the electrolytic device 01 is a component for electrolyzing copper, having a cathode and an anode, which is a prior art and will not be described in detail. The waste liquid treatment device 02 is a component for treating purified waste liquid, which can be a purification pipeline with a water inlet 06 and a water outlet 07 at both ends to control the inflow and outflow of waste liquid, or a purification tank, or a purification tank, etc., but is not limited thereto. The microbial plate 08 is a component for treating various heavy metal ions and sulfuric acid in the waste liquid, and the surface of the microbial plate 08 contains microorganisms that can treat heavy metal ions and other substances, such as bacteria that can use microbial metabolites to adsorb heavy metal ions, or microorganisms that can reduce heavy metal ions to low valence state, etc., but is not limited thereto. The waste water filter 09 is a component for treating large particle harmful substances such as anode mud, which can be a polyester filter screen, or a sponge, etc., but is not limited thereto. The waste gas treatment device 03 is a component for treating harmful gas generated in the electrolytic device 01, which can be a filter pipeline, or a treatment tank, etc., but is not limited thereto. The waste gas filter 13 is a component for filtering large particle solid dust in the air, which can be activated carbon filter adsorption, or a filter membrane, etc., but is not limited thereto. The purification component 14 is a component for purifying harmful gas in the waste gas, which can be a microbial plate, or activated carbon absorption, etc., but is not limited thereto. When the waste gas treatment device 03 inhales waste gas through the air inlet 11, the waste gas is first removed by the waste gas filter 13 located below the air inlet, and then the high-temperature waste gas passes through the heat collecting pipe 16 and is cooled by the heat collecting pipe 16, and then sinks to the bottom of the purification component 14, and then is purified by the purification component 14, and then is discharged from the exhaust port 12 of the waste gas treatment device 03.

[0024] As can be seen from the above, the electrolytic copper waste gas and waste liquid separation type recovery equipment provided by the embodiment can simultaneously treat waste gas and waste liquid by setting the waste gas treatment device 03 and the waste liquid treatment device 02, and the waste gas treatment device 03 and the waste liquid treatment device 02 adopt different purification processes, which can more targetedly treat waste gas and waste liquid, and achieve better purification effect and better protect the environment. At the same time, the waste gas treatment device 03 and the waste liquid treatment device 02 both contain heat collecting pipes 16 to utilize waste heat, achieving energy saving effect.

[0025] Optionally, in some embodiments, referring to Figure 2 , the electrolytic device 01 further comprises a first filter 15 installed on the top and below the air outlet for filtering the waste gas for the first time.

[0026] It can be understood that the first filter 15 is used for preliminary filtering of the exhaust gas, which can be a filter screen, a filter plate, etc., but is not limited thereto

[0027] In this way, the exhaust gas is filtered once before entering the outlet 04, enhancing the purification effect.

[0028] Optionally, in some embodiments, referring to Figure 3 The waste liquid treatment device 02 also has a slot 10 for inserting the microbial plate 08 and the wastewater filter 09, and multiple microbial plates 08 can be arranged in the waste liquid treatment device 02 at the same time.

[0029] It can be understood that the waste liquid treatment device 02 is a closed container, and the microbial plate 08 and the wastewater filter 09 also have a partitioning function between the water inlet and the water outlet, dividing the waste liquid treatment device 02 into two parts. After the wastewater enters through the water inlet 06, it passes through the microbial plate 08 and the wastewater filter 09, and is then discharged through the water outlet 07. Therefore, the microbial plate 08 and the wastewater filter 09 are fixed in the wastewater treatment device 02 by the slot 10. The wastewater filter 09 and the microbial plate 08 have different purification effects due to different combination modes, for example, the wastewater filter can be installed near the water inlet end, followed by parallel microbial plates, or the wastewater filter 09 can be installed between several microbial plates 08, etc., but is not limited thereto.

[0030] In this way, the waste liquid needs to pass through multiple layers of wastewater filters 09 and multiple layers of microbial plates 08, and the multiple layers of filtering devices can enhance the filtering effect and shorten the filtering time.

[0031] Optionally, in some embodiments, referring to Figure 1 The air suction pump 17 for sucking the exhaust gas is also installed on the air pipe between the electrolysis device 01 and the exhaust gas treatment device 03. The waste liquid treatment device 02 and the exhaust gas treatment device 03 are integrally installed.

[0032] It can be understood that the exhaust gas treatment device 03 and the waste liquid treatment device 02 are two separate closed treatment devices, for example, they can be separated by a partition in the same closed container, or they can be two separate closed containers, etc., but are not limited thereto.

[0033] In this way, the exhaust gas and the waste liquid can be purified at the same time, reducing the purification time and improving the purification efficiency. At the same time, different purification components are used for the exhaust gas and the waste liquid, enhancing the purification effect.

[0034] From the above, when the electrolysis device completes electrolysis, the exhaust gas treatment device 03 is opened, the suction pump sucks the exhaust gas in the electrolysis device into the exhaust gas treatment device 03, the exhaust gas enters the exhaust gas treatment device 03 and is filtered through the exhaust gas filter, then is cooled by the heat collecting pipe, and then the gas sinks to the purification part, and after the purification part completes purification, is discharged from the exhaust port. At the same time, the lower waste liquid treatment device is opened, the waste liquid flows into the waste liquid treatment device, then flows through the microbial plate and the wastewater filter, and after being purified by the wastewater filter and the microbial plate, flows to the drain port and flows out from the drain port.

[0035] The above merely describes a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art, within the technical range disclosed by the present application, according to the technical scheme and the improved conception of the present application, should be covered in the protection scope of the present application.
