Description

Technical Field

[0001] The invention belongs to the technical field of soybean wastewater purification, in particular to a soybean protein wastewater treatment device and a treatment method. Background Art

[0002] Soy protein, the full name of which is soybean protein, is the only complete protein in plants that is similar to animal protein, and is superior to animal protein because it does not contain cholesterol. A large amount of sewage will be generated during the production process of soybean protein. If it is not treated in time, direct discharge will lead to serious environmental pollution. Soy protein wastewater mainly comes from the alkali washing, acid precipitation, water washing and other processes in the above-mentioned process. The wastewater contains soybean components, which will show different states in different acidity and alkalinity and different treatment processes. The content of N, P and other substances in soybean protein wastewater is relatively high, which can cause eutrophication of water bodies, and the organic matter content is high. The wastewater is prone to rancidity and releases foul-smelling gases such as hydrogen sulfide.

[0003] A patent with the announcement number CN 221166096 U discloses a flotation device for pretreatment of soybean protein wastewater, including a treatment box, the treatment box including a reaction zone, a dissolved gas release zone, a separation zone and a slag collection zone, the reaction zone is used to put in PAC agents and PAM agents, the reaction zone is provided with a stirring component, the stirring component is used to mix the PAC agents and PAM agents with wastewater, and the treatment box is provided with a bubble release component. This patent uses the stirring component to fully stir and mix the agent and the wastewater, and then separates and diffuses the bubbles under the action of the bubble diffuser, so that the bubbles are evenly dispersed in the separation zone, the bubble contact time and surface area are increased, and the contact effect of the bubbles and the suspended matter is improved, so as to improve the flotation efficiency in the treatment of soybean protein wastewater.

[0004] In the current prior art, when the existing soy protein wastewater is treated again, many of them are treated by photocatalytic oxidation treatment, adsorption treatment, low-temperature plasma treatment and water absorption method, but the soy protein wastewater is purified and relies on the biochemical action of aerobic bacteria and anaerobic bacteria to complete the process of treatment. Since the optimal growth temperature of aerobic microorganisms is usually between 20℃ and 40℃. Within this temperature range, the metabolic activity of microorganisms is most active and can effectively degrade organic matter, but the existing aerobic treatment device cannot control the temperature of the wastewater, and generally keeps it at room temperature. The temperature of the wastewater at room temperature is lower than the minimum temperature of 20°, and the growth rate and activity of microorganisms in the wastewater below 20° will be reduced.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Example 1

[0035] like Figures 1 to 6 and Figure 7 - Figure 8As shown, a soybean protein wastewater treatment device according to an embodiment of the present invention comprises a wastewater treatment box 11 and a support frame 12 fixedly installed on the outer surface of the wastewater treatment box 11, a drain pipe 13 detachably installed at the bottom edge position of one side of the wastewater treatment box 11, and a fixing plate 14 fixedly installed on the other side surface of the wastewater treatment box 11. An incineration chamber 111 is fixedly connected to the top surface of the wastewater treatment box 11, a thermostat 112 is fixedly installed on one side surface of the incineration chamber 111 and at the top edge position, an exhaust heating plate 113 extending from the inner wall surface through the wastewater treatment box 11 is fixedly connected to the output end of the thermostat 112, an air guide pipe 114 is fixedly connected to the other side surface of the incineration chamber 111, and one end of the air guide pipe 114 is fixedly connected to a A closed shell 115 is arranged on the outer surface, and a fuel burner 118 arranged on the edge of one side of the incineration chamber 111 is fixedly installed on the top surface of the wastewater treatment box 11, and a flame head 119 arranged on the inner wall surface of the bottom of the incineration chamber 111 is fixedly installed on the output end of the fuel burner 118, and a notch is provided at the connection between the flame head 119 and the incineration chamber 111; a conical shell c1 is fixedly installed on the inner wall surface of the wastewater treatment box 11, and a drainage air duct c3 is fixedly connected to the bottom edge surface of one side of the conical shell c1, a closing plate 116 is swingably connected to the bottom surface of the closed shell 115, and a filter cotton 117 movably sleeved on the inner wall surface of the closed shell 115 is fixedly connected to the surface of the closing plate 116, and one side surface of the closed shell 115 is connected to one end of the drainage air duct c3.

[0036] At the same time, the exhaust gas in the conical casing c1 is injected into the closed casing 115 through the drainage air duct c3, and some particulate impurities and water vapor in the exhaust gas are filtered with the filter cotton 117, and the cooled exhaust gas is guided into the combustion chamber 111 through the air guide pipe 114, and the fuel is injected into the interior of the flame head 119 with the oil burner 118 to burn the exhaust gas accumulated in the combustion chamber 111, and the organic substances such as VOCs in the exhaust gas are oxidized and decomposed into corresponding carbon dioxide and water by high temperature, thereby purifying the exhaust gas. The waste gas is oxidized to ensure that the organic matter is fully oxidized, and most of the hot gas is output. A part of the hot gas will pass through the thermostat 112, and then the high temperature environment will be cooled to between 20° and 40° by the thermostat 112, and the exhaust heating plate 113 on the output end of the thermostat 112 will be used to inject the constant temperature hot air flow into the wastewater inside the wastewater treatment box 11, so as to increase the wastewater temperature, thereby achieving the effect of utilizing the temperature range between 20°C and 40°C, where the metabolic activity of microorganisms is most active, and accelerating the internal degradation rate of soybean protein wastewater.

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

[0038] The processed soybean protein wastewater is poured into the interior of the wastewater treatment box 11 in a small amount and evenly, and at the same time, the filtering shell c4 on the inner wall of the top conical shell c1 contacts the falling soybean protein wastewater, and the filtering shell c4 is used to filter out the soybean broken particles in the soybean protein wastewater, and at the same time, the conical shell c1 is used to reduce the speed of the passing soybean protein wastewater layer by layer, and at the same time, the soybean protein wastewater increases the gas inside the wastewater when passing through the conical shell c1, so as to achieve the effect of using the grid plate at the bottom of the conical shell c1 to perform multiple differentiation on the soybean protein wastewater, thereby increasing the bubbles inside the soybean protein wastewater and increasing the oxygen content inside the soybean protein wastewater.

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

[0040] When the soy protein wastewater enters the bottom layer 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, so that the surface of the stirring plate 143 and the soy protein wastewater inside the wastewater treatment tank 11 are continuously stirred, further increasing the oxygen content inside the soy protein wastewater, and also increasing the emission of waste gas inside the soy protein wastewater. The interior of the wastewater treatment tank 11 in a semi-closed state will be in an aerobic environment, achieving the goal of using aerobic bacteria to complete the soy protein wastewater treatment process. Aerobic microorganisms will accelerate the degradation of organic matter in the soy protein wastewater, and during the reaction process, basically no excessive odor will be generated, and the pollution to the environment will be relatively small.

[0041] like Figure 1 - Figure 3 and Figure 5 - Figure 8As shown, a lap shell a1 is fixedly connected to the inner wall of the incineration chamber 111, and the position of the lap shell a1 is set at the top edge of the flame head 119, and a staggered guide plate a2 is fixedly connected to the inner wall of the lap shell a1, and the gap between the two sets of lap shells a1 is set at the entrance and exit of one end of the air guide pipe 114, and the inner wall of the wastewater treatment tank 11 and the guide inclined plate 1110 located on the bottom edge of the conical shell c1, and the bottom surface of the guide inclined plate 1110 is set at the top edge of the pushing stirring plate 143, and a hydraulic rod 1111 is fixedly installed on the top inner wall of the wastewater treatment tank 11, and the output end of the hydraulic rod 1111 is fixedly connected to an extrusion closing plate 1112 that is movably overlapped on one end of the discharge pipe 13.

[0042] When the exhaust gas inside the incineration chamber 111 is incinerated again, the hot air flow will expand due to the increase in temperature, the volume will increase, and the density will decrease. When the air flow passes through the inner wall of the staggered guide plate a2, the gas flow rate will change due to the change in the cross-sectional area of ​​the channel. In addition, the channel formed between the staggered guide plates a2 is narrow. After the hot air flow expands, the flow rate will increase due to space limitations. The increase in speed will drive the air flow at the bottom of the staggered guide plate a2 to flow upward. As the gas at the bottom of the incineration chamber 111 decreases and the pressure difference between the inside and outside of the incineration chamber 111 changes, the outside air will quickly pass through the gap between the flame head 119 and the incineration chamber 111 and quickly enter the interior of the incineration chamber 111, providing oxygen content for the incineration of the flame head 119.

[0043] Example 2

[0044] like Fig. 9 As shown, a method for treating soybean protein wastewater comprises the following steps:

[0045] S1. The soybean protein wastewater is directed into the separation box, and the soybean impurities in the soybean protein wastewater are filtered out with a filter;

[0046] S2. The falling soybean protein wastewater is decelerated in multiple layers, and the exhaust fan is used to absorb the residual waste gas in the diversion channel, and the fan is used to guide the waste gas into the incineration chamber for incineration;

[0047] S3. High-temperature incineration can burn away the microorganisms and residual impurities in the waste gas, and at the same time recycle part of the rising hot air flow, and cool the hot air flow to keep it between 20° and 40°. Then, the hot air flow is guided into the stirring chamber through the air pipe, and the waste water is heated to between 20° and 40° by the high-temperature air flow, so as to increase the activity of the microorganisms.

[0048] S4. The organic waste gas is fully mixed with the fuel gas at high temperature, and completely burned under the catalysis of the catalyst aluminum oxide, thereby completely oxidizing and decomposing the organic waste gas.

[0049] Working principle: The processed soybean protein wastewater is poured into the wastewater treatment box 11 in a small amount and evenly, and the filter shell c4 on the inner wall of the top conical shell c1 is used to contact the falling soybean protein wastewater, and the filter shell c4 is used to filter the soybean broken particles in the soybean protein wastewater, and the conical shell c1 is used to reduce the speed of the passing soybean protein wastewater layer by layer. At the same time, the soybean protein wastewater increases the gas inside the wastewater when passing through the conical shell c1, so as to achieve the effect of using the grid plate at the bottom of the conical shell c1 to perform multiple differentiation on the soybean protein wastewater, thereby increasing the bubbles inside the soybean protein wastewater and increasing the oxygen content inside the soybean protein wastewater;

[0050] When the soybean protein wastewater enters the bottom layer of the wastewater treatment box 11, the hydraulic rod 141 on the outer surface of the fixed plate 14 pushes the stirring plate 143 back and forth, so that the surface of the stirring plate 143 and the soybean protein wastewater inside the wastewater treatment box 11 are continuously stirred, further increasing the oxygen content inside the soybean protein wastewater, and also increasing the emission of waste gas inside the soybean protein wastewater. The interior of the wastewater treatment box 11 in a semi-closed state will be in an aerobic environment, achieving the use of 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 in the reaction process, basically no excessive odor will be generated, and the pollution to the environment will be relatively small.

[0051] At the same time, the exhaust gas in the conical casing c1 is injected into the closed casing 115 through the drainage air duct c3, and some particulate impurities and water vapor in the exhaust gas are filtered with the filter cotton 117, and the cooled exhaust gas is guided into the combustion chamber 111 through the air guide pipe 114, and the fuel is injected into the interior of the flame head 119 with the oil burner 118 to burn the exhaust gas accumulated in the combustion chamber 111, and the organic substances such as VOCs in the exhaust gas are oxidized and decomposed into corresponding carbon dioxide and water by high temperature, thereby purifying the exhaust gas. The waste gas is oxidized to ensure that the organic matter is fully oxidized, and most of the hot gas is output. A part of the hot gas will pass through the thermostat 112, and then the high temperature environment is cooled to between 20° and 40° by the thermostat 112, and the exhaust heating plate 113 on the output end of the thermostat 112 is used to inject the constant temperature hot air flow into the wastewater inside the wastewater treatment box 11, so as to increase the wastewater temperature, so as to achieve the effect of utilizing the temperature range between 20°C and 40°C, in which the metabolic activity of microorganisms is most active, and accelerating the internal degradation rate of soybean protein wastewater;

[0052] When the exhaust gas inside the incineration chamber 111 is incinerated again, the hot air flow will expand due to the increase in temperature, the volume will increase, and the density will decrease. When the air flow passes through the inner wall of the staggered guide plate a2, the gas flow rate will change due to the change in the cross-sectional area of ​​the channel. In addition, the channel formed between the staggered guide plates a2 is narrow. After the hot air flow expands, the flow rate will increase due to space limitations. The increase in speed will drive the air flow at the bottom of the staggered guide plate a2 to flow upward. As the gas at the bottom of the incineration chamber 111 decreases and the pressure difference between the inside and outside of the incineration chamber 111 changes, the outside air will quickly pass through the gap between the flame head 119 and the incineration chamber 111 and quickly enter the interior of the incineration chamber 111, providing oxygen content for the incineration of the flame head 119.
