Description

Technical Field

[0001] This invention belongs to the field of soybean wastewater purification technology, specifically a soybean protein wastewater treatment equipment and treatment method. Background Technology

[0002] Soy protein, also known as soybean protein, is the only complete protein among plant-based proteins that is similar to animal protein. It is superior to animal protein because it contains no cholesterol. The production of soybean protein generates a large amount of wastewater. If not treated promptly, direct discharge will lead to serious environmental pollution. Soybean protein wastewater mainly comes from the alkaline washing, acid precipitation, and water washing processes mentioned above. The wastewater contains soybean components, which exhibit different states depending on the acidity / alkalinity and the treatment process. Soybean protein wastewater has high levels of nitrogen (N) and phosphorus (P), which can cause eutrophication of water bodies. Furthermore, its high organic matter content makes it prone to rancidity, releasing malodorous gases such as hydrogen sulfide.

[0003] A patent with publication number CN 221166096 U discloses an air flotation device for the pretreatment of soybean protein wastewater, including a treatment tank comprising a reaction zone, a dissolved gas release zone, a separation zone, and a sludge collection zone. The reaction zone is used to add PAC and PAM reagents, and a stirring assembly is provided within the reaction zone to mix the PAC and PAM reagents with the wastewater. A bubble release assembly is also provided on the treatment tank. This patent utilizes the stirring assembly to thoroughly mix the reagents and wastewater, and then, under the action of the bubble diffuser, separates and diffuses the bubbles, uniformly dispersing them within the separation zone. This increases the bubble contact time and surface area, improving the contact effect between the bubbles and suspended matter, thereby enhancing the air flotation efficiency in soybean protein wastewater treatment.

[0004] Currently, existing technologies for treating soybean protein wastewater often employ methods such as photocatalytic oxidation, adsorption, low-temperature plasma treatment, and water absorption. However, the purification of soybean protein wastewater relies on the biochemical action of aerobic and anaerobic bacteria. The optimal growth temperature for aerobic microorganisms is typically between 20°C and 40°C. Within this temperature range, their metabolic activity is most active, effectively degrading organic matter. However, existing aerobic treatment devices cannot control the wastewater temperature, generally maintaining it at room temperature. At room temperature, the wastewater temperature is below the minimum 20°C, which reduces the growth rate and activity of microorganisms.

[0005] Therefore, the present invention provides a soybean protein wastewater treatment device and treatment method. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Firstly, the technical solution adopted by the present invention to solve its technical problem is as follows: A soybean protein wastewater treatment device according to the present invention includes a wastewater treatment tank and a support frame fixedly installed on the outer surface of the wastewater treatment tank, a drain pipe detachably installed at the bottom edge of one side of the wastewater treatment tank, a fixing plate fixedly installed on the other side surface of the wastewater treatment tank, an incineration chamber fixedly connected to the top surface of the wastewater treatment tank, a temperature controller fixedly installed on one side surface of the incineration chamber at the top edge, and an output end of the temperature controller fixedly connected to an extension penetrating the wastewater treatment tank and extending to the inner side. The exhaust heating plate on the wall is fixedly connected to the other side surface of the incineration chamber. A gas guide pipe is fixedly connected to one end of the gas guide pipe and a closed sleeve set on the outer surface of the support frame. A fuel burner is fixedly installed on the top surface of the wastewater treatment tank and is located at one edge of the incineration chamber. A burner head is fixedly installed on the output end of the fuel burner and is located on the inner wall of the bottom of the incineration chamber. A slot is provided at the connection between the burner head and the incineration chamber. A conical sleeve is fixedly installed on the inner wall of the wastewater treatment tank and a duct is fixedly connected to the bottom edge surface of one side of the conical sleeve.

[0008] Preferably, a closing plate is oscillatingly connected to the bottom surface of the closed housing, and a filter cotton that is movably sleeved on the inner wall of the closed housing is fixedly connected to the surface of the closing plate. One side surface of the closed housing is connected to one end of the air duct.

[0009] Preferably, a filter housing is provided on the top inner wall of the conical housing, a filter deceleration plate is provided on the bottom surface of the conical housing at the junction of the air duct and the conical housing, and the outer surface of the air duct is fixedly connected to the outer surface of the wastewater treatment tank.

[0010] Preferably, an overlapping sleeve is fixedly connected to the inner wall of the combustion chamber, and the overlapping sleeve is positioned at the top edge of the burner head. An interlaced guide plate is fixedly connected to the inner wall of the overlapping sleeve, and the gap between the two sets of overlapping sleeves is located at one end of the gas duct inlet.

[0011] Preferably, a hydraulic rod two is fixedly installed on the inner wall of the fixed plate, the output end of the hydraulic rod two is movably sleeved on the outer surface of the wastewater treatment tank, and a pushing and stirring plate that is movably overlapped on the inner wall of the bottom of the wastewater treatment tank is fixedly connected to the output end of the hydraulic rod two.

[0012] Preferably, the outer surface of the pushing and stirring plate is fixedly connected to a diversion groove that slides onto the inner wall of the wastewater treatment tank, and the outer surface of the pushing and stirring plate is fixedly connected to a limiting rod that is movably sleeved on the outer surface of the wastewater treatment tank.

[0013] Preferably, the wastewater treatment tank has a guide plate on its inner wall and located at the bottom edge of the conical shell, and the bottom surface of the guide plate is located at the top edge of the pushing and stirring plate. A hydraulic rod is fixedly installed on the top inner wall of the wastewater treatment tank, and a squeezing and closing plate that is movably connected to one end of the drain pipe is fixedly connected to the output end of the hydraulic rod.

[0014] Secondly, a method for treating soybean protein wastewater includes the following steps:

[0015] S1. The soybean protein wastewater is guided into the separation tank, and at the same time, the soybean impurities inside the soybean protein wastewater are filtered out using a filter screen.

[0016] S2. The falling soybean protein wastewater is decelerated in multiple layers. At the same time, the exhaust fan absorbs the residual exhaust gas inside the guide channel and guides the exhaust gas into the incineration chamber for incineration.

[0017] S3. High-temperature incineration can burn off the microorganisms and residual impurities inside the waste gas, while recovering the rising hot gas flow and cooling the hot gas flow to maintain it between 20° and 40°. The hot gas flow is then guided into the mixing chamber through the gas pipe, and the wastewater is heated to between 20° and 40° by the high-temperature gas flow, thereby increasing the activity of microorganisms.

[0018] S4. At high temperature, the organic waste gas is fully mixed with the fuel gas and completely combusted under the catalysis of aluminum oxide, thereby thoroughly oxidizing and decomposing the organic waste gas.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The soybean protein wastewater treatment equipment and method of the present invention involves cooling the waste gas and guiding it through the gas guide pipe into the combustion chamber. Fuel is supplied to the burner head for combustion, burning the waste gas accumulated inside the combustion chamber. The high temperature oxidizes and decomposes organic matter such as VOCs in the waste gas into carbon dioxide and water, thereby purifying the waste gas and ensuring sufficient oxidation of organic matter. Most of the hot gas is discharged, with a portion passing through a constant temperature unit. The constant temperature unit then cools the high-temperature environment to between 20°C and 40°C. The constant-temperature hot gas is then supplied to the wastewater inside the wastewater treatment tank by the exhaust heating plate at the output end of the constant temperature unit, thereby increasing the wastewater temperature. This achieves the effect of utilizing the temperature range of 20°C to 40°C, where microbial metabolic activity is most active, thus accelerating the internal degradation rate of the soybean protein wastewater.

[0021] 2. The soybean protein wastewater treatment equipment and method of the present invention involves uniformly and in small quantities injecting the processed soybean protein wastewater into the interior of the wastewater treatment tank. Simultaneously, a filter sleeve on the inner wall of the top conical casing contacts the descending soybean protein wastewater, filtering out soybean particles from the wastewater. The conical casing further slows down the flow of the wastewater layer by layer, while the wastewater's gas content increases as it passes through the conical casing. This achieves the effect of multiple separations of the wastewater by the grid plate at the bottom of the conical casing, thereby increasing the number of bubbles and the oxygen content within the wastewater.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1

[0035] like Figures 1 to 6 and Figure 7 - Figure 8As shown, an embodiment of the present invention provides a soybean protein wastewater treatment device, comprising a wastewater treatment tank 11 and a support frame 12 fixedly installed on the outer surface of the wastewater treatment tank 11, a drain pipe 13 detachably installed on the bottom edge of one side of the wastewater treatment tank 11, a fixing plate 14 fixedly installed on the other side surface of the wastewater treatment tank 11, an incineration chamber 111 fixedly connected to the top surface of the wastewater treatment tank 11, a thermostat 112 fixedly installed on one side surface of the incineration chamber 111 at the top edge, an exhaust heating plate 113 extending through the wastewater treatment tank 11 to the inner wall fixedly connected to the output end of the thermostat 112, and a gas guide pipe 114 fixedly connected to the other side surface of the incineration chamber 111, with a fixed connection at one end of the gas guide pipe 114 to a component disposed on the support frame 12. A closed casing 115 is attached to the outer surface of the wastewater treatment tank 11. A fuel injector 118 is fixedly installed on the top surface of the wastewater treatment tank 11, located at one edge of the incineration chamber 111. A burner head 119 is fixedly installed on the output end of the fuel injector 118, located on the inner wall of the bottom of the incineration chamber 111. A slot is provided at the connection between the burner head 119 and the incineration chamber 111. A conical casing c1 is fixedly installed on the inner wall of the wastewater treatment tank 11. A duct c3 is fixedly connected to the bottom edge of one side of the conical casing c1. A closing plate 116 is oscillatingly connected to the bottom surface of the closed casing 115. A filter cotton 117 is fixedly connected to the surface of the closing plate 116, which is movably sleeved on the inner wall of the closed casing 115. One side of the closed casing 115 is connected to one end of the duct c3.

[0036] Simultaneously, the exhaust gas inside the conical casing C1 is pumped into the closed casing 115 through the duct c3. The filter cotton 117 filters out particulate impurities and moisture from the exhaust gas. The cooled exhaust gas is then guided through the duct 114 into the combustion chamber 111, where fuel is supplied to the burner head 119 via the fuel injector 118 for combustion. This process burns the accumulated exhaust gas within the combustion chamber 111, oxidizing and decomposing organic matter such as VOCs into carbon dioxide and water through high temperature, thus purifying the exhaust gas. The waste gas is oxidized to ensure that the organic matter is fully oxidized. Most of the hot gas is discharged, and a portion of the hot gas passes through the thermostat 112. The thermostat 112 then cools the high-temperature environment to between 20°C and 40°C. In conjunction with the exhaust heating plate 113 on the output end of the thermostat 112, the constant-temperature hot gas is injected into the wastewater inside the wastewater treatment tank 11 to increase the wastewater temperature. This achieves the effect of utilizing the temperature range of 20°C to 40°C, where the metabolic activity of microorganisms is most active, thus accelerating the internal degradation rate of soybean protein wastewater.

[0037] like Figure 1 - Figure 3 , Figure 8As shown, a filter sleeve c4 is provided on the top inner wall of the conical sleeve c1, and a filter deceleration plate c2 is provided on the bottom surface of the conical sleeve c1 and at the junction of the air duct c3 and the conical sleeve c1. The outer surface of the air duct c3 is fixedly connected to the outer surface of the wastewater treatment tank 11.

[0038] The processed soybean protein wastewater is poured into the wastewater treatment tank 11 in small, even amounts. Simultaneously, the filter shell c4 on the inner wall of the top conical shell c1 comes into contact with the falling soybean protein wastewater. The filter shell c4 filters out soybean particles from the wastewater. The conical shell c1 then gradually slows down the flow of the wastewater as it passes through. As the wastewater passes through the conical shell c1, the gas content inside the wastewater increases. This achieves the effect of multiple separation of the soybean protein wastewater by the grid plate at the bottom of the conical shell c1, thereby increasing the number of bubbles inside the wastewater and increasing the oxygen content.

[0039] like Figure 2 , Figure 7 As shown, a hydraulic rod 141 is fixedly installed on the inner wall of the fixed plate 14. The output end of the hydraulic rod 141 is movably sleeved on the outer surface of the wastewater treatment tank 11. A pushing and stirring plate 143 is fixedly connected to the output end of the hydraulic rod 141 and is movably overlapped on the inner wall of the bottom of the wastewater treatment tank 11. A diversion groove 144 is fixedly connected to the outer surface of the pushing and stirring plate 143 and is slidably overlapped on the inner wall of the wastewater treatment tank 11. A limiting rod 142 is fixedly connected to the outer surface of the pushing and stirring plate 143 and is movably sleeved on the outer surface of the wastewater treatment tank 11.

[0040] When soybean protein wastewater enters the bottom of the wastewater treatment tank 11, the hydraulic rod 141 on the outer surface of the fixed plate 14 pushes the stirring plate 143 back and forth, causing the surface of the stirring plate 143 to continuously stir the soybean protein wastewater inside the wastewater treatment tank 11. This further increases the oxygen content inside the soybean protein wastewater and also increases the emission of waste gas inside the soybean protein wastewater. The semi-enclosed wastewater treatment tank 11 is in an aerobic environment, achieving the goal of using aerobic bacteria to complete the soybean protein wastewater treatment process. Aerobic microorganisms will accelerate the degradation of organic matter inside the soybean protein wastewater, and during the reaction process, there will be virtually no excessive odor, resulting in relatively low environmental pollution.

[0041] like Figure 1 - Figure 3 and Figure 5 - Figure 8As shown, an overlapping sleeve a1 is fixedly connected to the inner wall of the incineration chamber 111, and the overlapping sleeve a1 is located at the top edge of the burner head 119. An interlaced flow guide plate a2 is fixedly connected to the inner wall of the overlapping sleeve a1. The gap between the two sets of overlapping sleeves a1 is located at the inlet and outlet of one end of the gas guide pipe 114. A flow guide plate 1110 is located on the inner wall of the wastewater treatment tank 11 and at the bottom edge of the conical sleeve c1. The bottom surface of the flow guide plate 1110 is located at the top edge of the pushing and stirring plate 143. A hydraulic rod 1111 is fixedly installed on the top inner wall of the wastewater treatment tank 11. A compression closing plate 1112 is fixedly connected to the output end of the hydraulic rod 1111 and is movably overlapped on one end of the drain pipe 13.

[0042] When the waste gas inside the combustion chamber 111 is burned again, the hot gas flow expands due to the increase in temperature, its volume increases, and its density decreases. When the gas flow passes between the inner walls of the staggered guide plates a2, the gas flow velocity changes due to the change in the cross-sectional area of ​​the channel. In addition, the channel formed between the staggered guide plates a2 is relatively narrow, and the flow velocity of the hot gas flow increases due to space constraints after expansion. The increase in velocity will drive the gas flow at the bottom of the staggered guide plates a2 to flow upward. As the gas at the bottom of the combustion chamber 111 decreases, the pressure difference between the inside and outside of the combustion chamber 111 changes, and the outside air will quickly pass through the gap between the burner head 119 and the combustion chamber 111 and quickly enter the interior of the combustion chamber 111 to provide oxygen for the combustion of the burner head 119.

[0043] Example 2

[0044] like Figure 9 As shown, a method for treating soybean protein wastewater includes the following steps:

[0045] S1. The soybean protein wastewater is guided into the separation tank, and at the same time, the soybean impurities inside the soybean protein wastewater are filtered out using a filter screen.

[0046] S2. The falling soybean protein wastewater is decelerated in multiple layers. At the same time, the exhaust fan absorbs the residual exhaust gas inside the guide channel and guides the exhaust gas into the incineration chamber for incineration.

[0047] S3. High-temperature incineration can burn off the microorganisms and residual impurities inside the waste gas, while recovering the rising hot gas flow and cooling the hot gas flow to maintain it between 20° and 40°. The hot gas flow is then guided into the mixing chamber through the gas pipe, and the wastewater is heated to between 20° and 40° by the high-temperature gas flow, thereby increasing the activity of microorganisms.

[0048] S4. At high temperature, the organic waste gas is fully mixed with the fuel gas and completely combusted under the catalysis of aluminum oxide, thereby thoroughly oxidizing and decomposing the organic waste gas.

[0049] Working principle: The processed soybean protein wastewater is poured into the wastewater treatment tank 11 in small and uniform amounts. At the same time, the filter shell c4 on the inner wall of the top conical shell c1 comes into contact with the falling soybean protein wastewater. The filter shell c4 filters out soybean particles in the wastewater. The conical shell c1 then slows down the passing soybean protein wastewater layer by layer. As the wastewater passes through the conical shell c1, the gas inside the wastewater increases. The grid plate at the bottom of the conical shell c1 further breaks down the soybean protein wastewater, thereby increasing the number of bubbles inside the wastewater and increasing the oxygen content.

[0050] When soybean protein wastewater enters the bottom of the wastewater treatment tank 11, the hydraulic rod 141 on the outer surface of the fixed plate 14 pushes the stirring plate 143 back and forth, causing the surface of the stirring plate 143 to continuously stir the soybean protein wastewater inside the wastewater treatment tank 11. This further increases the oxygen content inside the soybean protein wastewater and also increases the emission of waste gas inside the soybean protein wastewater. The semi-enclosed wastewater treatment tank 11 will be in an aerobic environment, achieving the goal of using aerobic bacteria to complete the soybean protein wastewater treatment process. Aerobic microorganisms will accelerate the degradation of organic matter inside the soybean protein wastewater, and during the reaction process, there will be virtually no excessive odor, resulting in relatively low environmental pollution.

[0051] Simultaneously, the exhaust gas inside the conical casing C1 is pumped into the closed casing 115 through the duct c3. The filter cotton 117 filters out particulate impurities and moisture from the exhaust gas. The cooled exhaust gas is then guided through the duct 114 into the combustion chamber 111, where fuel is supplied to the burner head 119 via the fuel injector 118 for combustion. This process burns the accumulated exhaust gas within the combustion chamber 111, oxidizing and decomposing organic matter such as VOCs into carbon dioxide and water through high temperature, thus purifying the exhaust gas. The waste gas is oxidized to ensure that the organic matter is fully oxidized. Most of the hot gas is discharged, and a portion of the hot gas passes through the thermostat 112. The thermostat 112 then cools the high-temperature environment to between 20°C and 40°C. In conjunction with the exhaust heating plate 113 on the output end of the thermostat 112, the constant-temperature hot gas is injected into the wastewater inside the wastewater treatment tank 11 to increase the wastewater temperature. This achieves the effect of utilizing the temperature range of 20°C to 40°C, where the metabolic activity of microorganisms is most active, to accelerate the internal degradation rate of soybean protein wastewater.

[0052] When the waste gas inside the combustion chamber 111 is burned again, the hot gas flow expands due to the increase in temperature, its volume increases, and its density decreases. When the gas flow passes between the inner walls of the staggered guide plates a2, the gas flow velocity changes due to the change in the cross-sectional area of ​​the channel. In addition, the channel formed between the staggered guide plates a2 is relatively narrow, and the flow velocity of the hot gas flow increases due to space constraints after expansion. The increase in velocity will drive the gas flow at the bottom of the staggered guide plates a2 to flow upward. As the gas at the bottom of the combustion chamber 111 decreases, the pressure difference between the inside and outside of the combustion chamber 111 changes, and the outside air will quickly pass through the gap between the burner head 119 and the combustion chamber 111 and quickly enter the interior of the combustion chamber 111 to provide oxygen for the combustion of the burner head 119.
