Description

Technical Field

[0001] This utility model relates to the field of water environment treatment technology, and in particular to an emulsifier feeding device. Background Technology

[0002] In wastewater treatment, emulsifiers primarily disrupt the oil-water emulsion state through high-speed shearing, breaking down the originally stable emulsion and promoting the aggregation and enlargement of oil droplets, thereby significantly improving the efficiency of subsequent oil-water separation. For example, in emulsion wastewater treatment processes, it is often used as the core equipment for demulsification pretreatment, effectively separating mineral oil, suspended solids, and harmful additives (such as surfactants) from wastewater. This creates favorable conditions for subsequent deep purification processes such as flotation, biological treatment, or filtration, ultimately achieving water purification and resource reuse.

[0003] During the wastewater treatment process, emulsifiers need to add chemicals such as demulsifiers, flocculants, and pH adjusters to the wastewater. Emulsifiers are equipped with a special feeding device to add the chemicals into their chambers.

[0004] Although existing emulsifier feeding devices can add multiple groups of agents, the agents are directly injected into the feeding device and then enter the emulsifier cavity, or mixed with wastewater and enter the emulsifier cavity together. Therefore, the various injected agents are unevenly distributed in the container, resulting in stratification. For example, one layer may have more demulsifier and less flocculant, while another layer may have less demulsifier and more flocculant. This causes the emulsifier to take a long time to break down the stability of oil droplets in the wastewater. Utility Model Content

[0005] The main purpose of this utility model is to provide an emulsifier feeding device. The Venturi mixer can initially mix the demulsifier and flocculant. Then, when the wastewater, demulsifier and flocculant pass through the static mixer together, the wastewater, demulsifier and flocculant can be further mixed to avoid uneven concentrations of the agents in different parts of the emulsifier cavity.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An emulsifier feeding device includes a hopper and a mixing cylinder. The bottom of the hopper is connected to the mixing cylinder through a first pipe. The device also includes a Venturi mixer. The outlet pipe of the Venturi mixer is connected to the mixing cylinder through a second pipe. A third pipe is installed on the connecting pipe of the Venturi mixer. A static mixer is fixed at the bottom of the mixing cylinder.

[0008] Furthermore, a fourth pipe is installed at the end of the inlet pipe of the Venturi mixer, and a first valve is installed on the inlet pipe.

[0009] Furthermore, a fifth pipe is installed at the end of the outlet pipe of the Venturi mixer, and a second valve is installed on the outlet pipe.

[0010] Furthermore, a third valve is installed on the third pipeline.

[0011] Furthermore, it also includes a feed cylinder, which is located between the discharge hopper and the mixing cylinder and is connected to the first pipe, and a sixth pipe is installed on the mixing cylinder.

[0012] Furthermore, a fourth valve is installed on the sixth pipeline.

[0013] Furthermore, a fifth valve and a flow meter are installed on the first pipeline.

[0014] Furthermore, a filter screen is placed inside the hopper.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The Venturi mixer of this invention can initially mix demulsifier and flocculant. Then, when wastewater, demulsifier and flocculant pass through the static mixer together, the wastewater, demulsifier and flocculant can be further mixed to ensure that the multiple groups of agents are evenly distributed and to avoid uneven concentrations of the agents in different parts of the emulsifier cavity.

[0017] The fourth valve of this invention can control the opening and closing of the sixth pipe. When the pH value of the wastewater is not within the required range, the pH adjuster can be injected into the feed cylinder through the sixth pipe, and then mixed with the wastewater to enter the mixing cylinder, and finally enter the emulsifier cavity to achieve the adjustment of the wastewater pH value.

[0018] The filter screen of this invention can intercept impurities in wastewater, and the filter screen is easy to disassemble and install, so that personnel can clean it regularly. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 1-3As shown, an emulsifier feeding device includes a hopper 1 and a mixing cylinder 8. The bottom of the hopper 1 is connected to the mixing cylinder 8 through a first pipe 3. The device also includes a Venturi mixer 9. The outlet pipe 904 of the Venturi mixer 9 is connected to the mixing cylinder 8 through a second pipe 10. A third pipe 13 is installed on the connecting pipe 903 of the Venturi mixer 9. A static mixer 12 is provided at the bottom of the mixing cylinder 8. The inlet end of the static mixer 12 is connected to the mixing cylinder 8, and the outlet end is located in the cavity of the emulsifier. A fourth pipe 16 is installed at the end of the inlet pipe 901 of the Venturi mixer 9. A first valve 15 is installed on the inlet pipe 901. A fifth pipe 17 is installed at the end of the outlet pipe 904 of the Venturi mixer 9. A second valve 11 is installed on the outlet pipe 904.

[0028] In this embodiment, such as Figure 1 As shown, the bottom drain port of the static mixer 12 is fixed inside the emulsifier cavity. Then, the fourth pipe 16 is connected to the pumping pipe for the demulsifier, and the third pipe 13 is connected to the pumping pipe for the flocculant. Figure 3 As shown, when pumping demulsifier and flocculant, the demulsifier enters the Venturi mixer 9 through the inlet pipe 901. When it flows through the narrowing section 902, the flow velocity increases, thereby converting static pressure energy into kinetic energy and forming a high-speed jet. This creates a low-pressure zone at the bottom of the connecting pipe 903. At this time, the flocculant enters the inlet pipe 901 under the action of the pump, and then enters the narrowing section 902 under the action of the low-pressure zone to contact the high-speed flowing demulsifier. Due to the pressure difference and turbulence, the demulsifier and flocculant are initially mixed. Then, they enter the mixing cylinder 8 through the outlet pipe 904 and the second pipe 10. During this process, wastewater enters the mixing cylinder 8 through the discharge hopper 1. Then, the wastewater, the mixed demulsifier and flocculant enter the emulsifier together through the static mixer 12. During this process, the static mixer 12 can further mix the wastewater, demulsifier and flocculant to avoid uneven concentrations of the agents in different parts of the emulsifier cavity.

[0029] The static mixer 12 is a spiral vane type static mixer, which is a high-efficiency pipeline mixing device without moving parts. Its working principle is based on the cutting, shearing, rotation and recombination effect generated when the fluid flows in a specially designed static unit, so as to achieve rapid and uniform mixing of multiple fluids. The working principles of the static mixer 12 and the venturi mixer 9 in this embodiment are existing technologies, and will not be described in detail here.

[0030] Among them, such as Figure 1 As shown, a third valve 14 is installed on the third pipe 13, and the third valve 14 can control the opening and closing of the third pipe 13.

[0031] like Figure 1 and Figure 2As shown, it also includes a feed cylinder 7, which is located between the discharge hopper 1 and the mixing cylinder 8 and is connected to the first pipe 3. A sixth pipe 6 is installed on the mixing cylinder 8, and a fourth valve 5 is installed on the sixth pipe 6. The sixth pipe 6 is connected to the conveying pipe for pumping pH adjuster. When the pH value of the wastewater does not meet the requirements, the fourth valve 5 is opened, thereby injecting the pumped pH adjuster into the feed cylinder 7 through the sixth pipe 6, and then mixing it with the wastewater to enter the mixing cylinder 8. Finally, it enters the emulsifier cavity through the static mixer 12.

[0032] The emulsifier comes with a built-in pH detection device to detect the pH value of wastewater. The pH range for oily emulsified wastewater is 8-10, and the pH range for high COD industrial wastewater is 9-10.

[0033] Among them, such as Figure 1 As shown, a fifth valve 2 and a flow meter 4 are installed on the first pipe 3. The fifth valve 2 can control the opening and closing of the first pipe 3, and the flow meter 4 can measure the amount of wastewater entering the emulsifier.

[0034] Among them, such as Figure 2 As shown, a filter screen 18 is placed inside the hopper 1. The filter screen 18 can intercept impurities in the wastewater, and the filter screen 18 is naturally placed through the tapered shape of the hopper 1, making it easy to disassemble for cleaning.

[0035] The working principle is as follows: First, the fourth pipe 16 is connected to the pumping pipe for demulsifier, the third pipe 13 is connected to the pumping pipe for flocculant, and the sixth pipe 6 is connected to the pumping pipe for pH adjuster. Then, the bottom drain port of the static mixer 12 is fixed inside the emulsifier cavity. When demulsifier and flocculant need to be added to the emulsifier cavity, the personnel control the demulsifier and flocculant delivery pumps respectively, so that the demulsifier enters the Venturi mixer 9 through the inlet pipe 901. During this process, the flow velocity of the demulsifier increases when it flows through the narrowing section 902, thereby converting static pressure energy into kinetic energy and forming a high-speed jet. This creates a low-pressure zone at the bottom of the connecting pipe 903. At this time, the flocculant enters the inlet pipe 901 under the action of the pump, and then... Under the influence of the low-pressure zone, the demulsifier enters the narrowing section 902 and comes into contact with the high-speed flowing demulsifier. Due to the pressure difference and turbulence, the demulsifier and flocculant are initially mixed. Then, the mixture enters the mixing cylinder 8 through the outlet pipe 904 and the second pipe 10. At the same time, the wastewater enters the mixing cylinder 8 through the feed hopper. Then, the wastewater, the mixed demulsifier and flocculant enter the emulsifier together through the static mixer 12. During this process, the static mixer 12 can further mix the wastewater, demulsifier and flocculant to avoid uneven concentrations of the agents in different parts of the emulsifier cavity. If the pH value of the wastewater is not within the required range, the fourth valve 5 is opened to inject the pumped pH adjuster into the feed cylinder 7 through the sixth pipe 6 to adjust the pH value of the wastewater.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
