Description

Technical Field

[0001] This utility model relates to the field of carbon source technology for kitchen waste, and in particular to an in-situ production device for converting oily wastewater from kitchen waste into emulsified oil carbon source. Background Technology

[0002] Biomass carbon sources have wide applications in groundwater pollution remediation and treatment. For example, emulsified oil, as a novel carbon source, can act as an electron donor to enhance the ability of microorganisms in soil and groundwater to remove pollutants. Oily wastewater from kitchen waste is characterized by high organic matter, high ammonia nitrogen, high oil content, and high salinity. Due to its rich organic matter content, converting it into emulsified oil is a good choice as a biomass carbon source; in other words, oily wastewater from kitchen waste can be used as a potential carbon source. Currently, the conversion of oily wastewater from kitchen waste into emulsified oil generally involves multiple steps, including oil-water separation, oil-water mixing, and emulsification. Each production step is completed independently, resulting in cumbersome operations and low production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an in-situ production device for converting oily wastewater from kitchen waste into an emulsified oil carbon source, addressing the existing technological situation.

[0008] Furthermore, both the first and second weir flow structures include a chute extending downward along the top surface of the corresponding sidewall, an opening that vertically penetrates the corresponding sidewall, and a weir flow baffle. The weir flow baffle is disposed in the chute, and the lower side and the left and right sides of the weir flow baffle are covered with sealing sheets. During the process of the weir flow baffle sliding up and down in the chute, the opening can be completely closed or completely opened. The weir flow baffle is provided with a scale pointer, and the corresponding sidewall is provided with a scale indicator structure.

[0020] This invention provides an in-situ production device for converting oily wastewater from kitchen waste into an emulsified oil carbon source. Firstly, a connecting pipe links a reaction tank and a transfer tank, creating a communicating vessel. Secondly, weir structures are installed in both the reaction tank and the transfer tank to quantitatively control their maximum liquid levels. After oil-water separation is completed in the reaction tank, the water volume in the reaction tank is first adjusted by a second weir structure, and then the oil volume is adjusted by a first weir structure, thus obtaining the target oil-water ratio for subsequent emulsification production. According to this design, this in-situ production device can quickly control the oil-water ratio and directly carry out the emulsification reaction after oil-water separation, greatly improving production efficiency and offering simple and easy-to-use operation.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Please see Figs. 1-2 As shown, an in-situ production device for converting oily wastewater from kitchen waste into an emulsified oil carbon source includes a reaction tank 1 and a transfer tank 9.

[0027] The reaction tank 1 is equipped with an inlet pipe 2 and a drain pipe 4 connected to it. The inlet pipe 2 is used to inject oily wastewater from kitchen waste into the reaction tank 1 (the inlet pipe 2 is connected to the inlet system, which provides oily wastewater from kitchen waste). The drain pipe 4 is used to discharge the carbon source of emulsified oil from the reaction tank 1 (the drain pipe 4 is connected to the collection system, which collects the obtained emulsified oil). A first weir structure is provided on one side wall of the reaction tank 1. The first weir structure is used to quantitatively control the highest liquid level in the reaction tank 1.

[0028] The bottom of the transfer tank 9 is connected to the bottom of the reaction tank 1 via a connecting pipe 10, and a drain valve 11 is provided on the connecting pipe 10. A second weir structure is provided on one side wall of the transfer tank 9, which is used to quantitatively control the highest liquid level in the transfer tank 9. The drain valve 11 is an electronic valve.

[0029] In the above technical solution, both the first weir structure and the second weir structure include a chute 12 extending downward along the top surface of the corresponding sidewall, an opening 18 perpendicularly penetrating the corresponding sidewall, and a weir baffle 14. The weir baffle 14 is disposed in the chute 12, and the lower side and the left and right sides of the weir baffle 14 are covered with sealing sheets 17 (generally rubber sheets). During the process of the weir baffle 14 sliding up and down in the chute, the opening 18 can be completely closed or completely opened. The weir baffle 14 is provided with a scale pointer 15, and the corresponding sidewall is provided with a scale indicator structure 13. The scale pointer 15 and the scale indicator structure 13 cooperate to indicate the height of the weir baffle 14.

[0030] Specifically, the scale pointer 15 is an elastic body, and a protrusion is provided at the end away from the weir baffle 14. The scale indicator structure 13 is a groove evenly arranged vertically on the corresponding side wall. The groove is adapted to and the position of the protrusion on the scale pointer 15 is corresponding. During the process of the weir baffle 14 sliding up and down in the slide groove 12, the protrusion on the scale pointer 15 can be switched to different grooves of the scale indicator structure 13.

[0031] Specifically, a weir outlet 16 is provided on the upper side of the weir baffle 14, and the weir outlet 16 is triangular. More specifically, a diversion groove 8 is provided at the corresponding position of the weir baffle 14 and the weir outlet to facilitate the diversion of liquid.

[0032] The in-situ production unit is also equipped with the following functional components:

[0033] The reaction tank 1 is equipped with a feeder 3, which is used to feed emulsifier into the reaction tank 1;

[0034] An ultrasonic instrument (with ultrasonic vibrating rod 5 of the ultrasonic instrument installed inside the reaction tank 1) is provided on the reaction tank 1. The ultrasonic instrument is used to provide emulsification reaction conditions.

[0035] A temperature controller (temperature probe 6 of the temperature controller is installed on the reaction tank 1) is connected to the reaction tank 1. The temperature controller is used to provide emulsification reaction conditions.

[0036] The reaction tank 1 is also equipped with an intelligent control board 7, and the feeder 3, ultrasonic instrument, temperature controller and drain valve 11 are all electrically connected to the intelligent control board 7.

[0037] Please see Figs. 1-3 As shown, based on this in-situ production device, the production steps for converting oily wastewater from kitchen waste into emulsified oil are as follows:

[0038] Oily wastewater from kitchen waste is injected into reaction tank 1 through inlet pipe 2, and oil-water separation is waited for.

[0039] After the oil-water separation is completed, adjust the second weir structure so that its weir baffle 14 is at the first preset height H1;

[0040] Open the drain valve 11 to connect the reaction tank 1 with the transfer tank 9. The water in the reaction tank 1 enters the transfer tank 9, and the water in the reaction tank 1 and the water in the transfer tank 9 are at the same height, H1 (excess water will be discharged from the second weir structure and collected in a container).

[0041] Close the drain valve 11 and adjust the first weir structure so that its weir baffle 14 is at the second preset height H2 (excess oil will be discharged from the first weir structure and collected in a container). At this time, the oil height in the reaction tank 1 is H2-H1, the oil-water ratio is (H2-H1) / H1, and the oil-water ratio is completed.

[0042] Turn on feeder 3 and add emulsifier into reaction tank 1. Then turn on the ultrasonic instrument and temperature controller to start the emulsification reaction until the emulsification reaction is completed.

[0043] It should be noted that after the reaction tank 1 and the transfer tank 9 form a communicating vessel, in reality, the liquid level in the reaction tank 1 is higher than the liquid level in the transfer tank 9, and the water in the reaction tank 1 is lower than the water in the transfer tank 9 (there is a height difference h). However, for oily wastewater from kitchen waste, since the oil-to-water ratio is generally 12:88 to 25:75, the height difference h can be ignored. That is, the water in the reaction tank 1 and the water in the transfer tank 9 can be regarded as being at the same height.

[0044] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
