Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an ethanol production wastewater recycling treatment device and its treatment process. Background Technology

[0002] Ethanol production primarily uses starchy and cellulose raw materials. Wastewater is generated during the production process, mainly from: raw material processing wastewater (wastewater generated during washing, soaking, and distillation of raw materials); fermentation wastewater (unutilized sugars, amino acids, organic matter, etc., flowing into the wastewater during biological fermentation); and distillation wastewater (containing a certain amount of ethanol due to the azeotropic properties of ethanol and water and periodic cleaning during distillation).

[0003] An invention patent with publication number CN120117793A discloses an ethanol production wastewater recycling system. This system includes two rotatable filter plates, a first filter plate and a second filter plate. By adjusting their deflection angles, the overlap of filter holes one and two can be changed, thereby adjusting the filtration area. Simultaneously, a movable block can be installed to clear the upper side of filter hole one during deflection, improving wastewater filtration efficiency. A baffle plate is also included, which scrapes away impurities adhering to the surface of filter plate one while simultaneously transferring internal impurities through liquid flow. These impurities are then partially separated by filter plate three, reducing the amount of impurities carried in the fluid and preventing frequent clogging of filter hole one later, further improving wastewater filtration efficiency. However, because the filter plates are always within the filter cylinder, despite the internal clearing mechanism, long-term impurity accumulation can still lead to clogging of the filter plates.

[0045] This invention provides a process for recycling ethanol production wastewater, comprising the following steps:

[0046] S1. Before using the equipment, adjust the screening mechanism, then introduce the ethanol production wastewater into the screening cylinder, turn on the screening mechanism, and perform the screening of the wastewater.

[0047] S2. Using a pump, the wastewater treated by the screening cylinder is introduced into the equalization tank, and the equalization mechanism is turned on to adjust the pH value of the wastewater.

[0049] S4. After the wastewater treatment is completed, use a pump to introduce the wastewater treated by the second processor into the equalization tank, and turn on the equalization mechanism to perform backflow cleaning of the equalization tank.

[0050] This invention provides an ethanol production wastewater recycling treatment device and its treatment process. It has the following beneficial effects:

[0051] 1. This ethanol production wastewater recycling treatment equipment and its treatment process pre-treats ethanol production wastewater by setting up a screening mechanism and filtration components. Two sets of liftable and horizontally movable filtration components are installed in the screening mechanism to intercept large particulate solid impurities in the wastewater. Because the height of the filtration components is easy to control, the height of the first and second filter discs can be adjusted during the water inlet process, avoiding the situation where long-term use of the same filter discs leads to clogging of the screening cylinder and failure to discharge water.

[0052] 2. The ethanol production wastewater recycling treatment equipment and its treatment process, by setting up a connecting component and a filter component, facilitates the separation of large particulate solid impurities from the filter component through contact between the connecting component and the filter component. By setting a first filter plate and a second filter plate in the filter component, with a first cross groove in the first filter plate and a second cross groove in the second filter plate, and connecting the first cross groove and the second cross groove by a first cross plate and a second cross plate in the connecting component, the first filter plate and the second filter plate are repeatedly deformed in the vertical direction, thereby promoting the detachment of solid impurities.

[0053] 3. The ethanol production wastewater recycling treatment equipment and its treatment process, through the setting of an adjustment mechanism, controls the flow direction of a large amount of wastewater by using a second motor to control the deflection of an arc-shaped plate before the wastewater enters the adjustment tank. After the wastewater enters the adjustment tank, the first motor controls the rotation of the plates to control a large-scale contact between the reagent and the wastewater, accelerating the adjustment process. After the wastewater has been treated, a third motor controls the rotation of the rotating column to control the opening of the channel, thereby discharging the wastewater.

[0054] 4. The ethanol production wastewater recycling treatment equipment and its treatment process, by setting up a screening mechanism and an adjustment mechanism, performs screening and pH adjustment of the wastewater in the pre-treatment stage of ethanol production wastewater treatment. The screening and adjustment mechanisms are set in the screening cylinder and the adjustment tank. The filter components and plates with sticky rails are used to intercept most of the large particulate impurities in the wastewater, so as to avoid equipment blockage caused by too many fixed impurities in the early treatment process.

[0064] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0065] like Figures 1-8 As shown, the present invention provides a technical solution: including a frame 1;

[0066] Screening cylinder 2 is installed inside the frame 1. The bottom of the screening cylinder 2 is equipped with a first water outlet pipe. The side wall of the screening cylinder 2 is provided with two grooves, which are symmetrically arranged.

[0067] The regulating tank 4 is installed inside the frame 1. The bottom of the regulating tank 4 is equipped with a second water outlet pipe, and there are three second water outlet pipes.

[0068] The first processor 6 is installed inside the frame 1. An oxidation treatment unit is set inside the first processor 6. A third water outlet pipe is installed at the bottom of the first processor 6.

[0069] The second processor 7 is installed inside the frame 1. The second processor 7 is equipped with a disinfection unit and a fourth water outlet pipe is installed at the bottom of the second processor 7.

[0070] Pump body 8, pump body 8 is installed inside frame 1, and multiple pump bodies 8 are provided;

[0071] The screening mechanism 3 is located inside the screening cylinder 2. The screening mechanism 3 includes a slide plate 303, which has a power system inside. Multiple slide plates 303 are provided. A connecting rod 305 is installed on the top of the slide plate 303. The connecting rod 305 is a U-shaped rod. A filter assembly 307 and a connecting assembly 306 are provided on the outside of the connecting rod 305. The slide plate 303 is used to control the filter assembly 307 to enter and exit the screening cylinder 2.

[0072] The regulating mechanism 5 is located inside the regulating pool 4. The regulating mechanism 5 includes a rotating column 511 and a channel 513. The rotating column 511 is a semi-cylinder. The channel 513 is located at the bottom of the regulating pool 4. There are three channels 513. The three channels 513 are connected to the second water outlet pipe. The rotating column 511 is used to control the opening and closing of the channels 513.

[0073] Before using the equipment, adjust the screening mechanism 3, then introduce the ethanol production wastewater into the screening cylinder 2, and turn on the screening mechanism 3 to screen the wastewater. After screening, use the pump 8 to introduce the wastewater treated by the screening cylinder 2 into the equalization tank 4, and turn on the equalization mechanism 5 to adjust the pH value of the wastewater. Then, use the pump 8 to introduce the wastewater treated by the equalization tank 4 into the first processor 6, and then introduce the wastewater treated by the first processor 6 into the second processor 7. After the wastewater treatment is completed, use the pump 8 to introduce the wastewater treated by the second processor 7 into the equalization tank 4, and turn on the equalization mechanism 5 to perform a backflow cleaning operation on the equalization tank 4.

[0074] Screening agency 3 also includes:

[0075] The first lifting rod 301 is installed on the top of the frame 1. There are two first lifting rods 301, which are arranged symmetrically.

[0076] There are two fixed frames 302, which are respectively installed on the top of the two first lifting rods 301. The slide plate 303 is slidably connected inside the fixed frame 302.

[0077] The first push rod 304 is installed inside the fixed frame 302, and the telescopic end of the first push rod 304 is connected to the slide plate 303.

[0078] Before using the equipment, activate the first lifting rod 301 to its second stroke. The first lifting rod 301 drives the fixed frame 302, the slide plate 303, the first push rod 304, the connecting rod 305, the connecting assembly 306, and the filter assembly 307 to move upward. Then, activate a symmetrical set of first push rods 304. The two first push rods 304 drive the two slide plates 303 to move towards the screening cylinder 2 until the filter assembly 307 is directly above the screening cylinder 2.

[0079] Then, the first lifting rod 301 is adjusted to the initial state. The first lifting rod 301 drives the filter component 307 into the screening cylinder 2. As the wastewater enters the screening cylinder 2, the wastewater flows downward through the connecting component 306, and large solid impurities are trapped in the connecting component 306.

[0080] As the screening process proceeds, the first lifting rod 301 is adjusted to the first stroke. The first lifting rod 301 drives part of the filter component 307 upward to separate from the screening cylinder 2. At this time, the wastewater moves downward through the middle part of the filter component 307.

[0081] Adjust the first lifting rod 301 to the second stroke. The first lifting rod 301 drives the filter component 307 to completely detach from the screening cylinder 2. The filter component 307 is left to stand, and a small amount of wastewater falls into the screening cylinder 2.

[0082] Before the second batch of wastewater is introduced, the power system in the slide plate 303 is adjusted, and another set of slide plates 303 is used to drive another filter component 307 to repeat the above work to treat the second batch of wastewater.

[0083] Filter assembly 307 includes:

[0084] Vertical rod 3071 is installed at the bottom of connecting rod 305;

[0085] Connecting shaft 3072 is installed inside vertical rod 3071, and multiple connecting shafts 3072 are provided;

[0086] The first filter disc 3073 is connected to the vertical rod 3071 via the connecting shaft 3072;

[0087] The second filter disc 3074 is connected to the vertical rod 3071 via a connecting shaft 3072. The size of the first filter disc 3073 is slightly larger than that of the second filter disc 3074. Both the first filter disc 3073 and the second filter disc 3074 are made of elastic material.

[0088] Through holes 3075 are provided in multiple ways. Some through holes 3075 are provided inside the first filter disc 3073, and other through holes 3075 are provided inside the second filter disc 3074.

[0089] The first cross groove 3076 is formed at the bottom of the first filter disc 3073 and penetrates the interior of the first filter disc 3073.

[0090] The second cross groove 3077 is located at the bottom of the second filter disc 3074, and the size of the first cross groove 3076 is slightly larger than that of the second cross groove 3077.

[0091] As the first lifting rod 301 drives the filter assembly 307 into the screening cylinder 2, the vertical rod 3071 at the bottom of the connecting rod 305 gradually enters the groove on the side wall of the screening cylinder 2, and both the first filter disc 3073 and the second filter disc 3074 are in the screening cylinder 2. Wastewater flows downward through the first filter disc 3073 and the second filter disc 3074, and most of the large solid particles are trapped in the first filter disc 3073.

[0092] As the first lifting rod 301 drives the first filter disc 3073 upward to detach from the screening cylinder 2, the second filter disc 3074 separately intercepts large solid impurities, thus avoiding the situation where the screening cylinder 2 becomes clogged and unable to output water due to the blockage of the first filter disc 3073 caused by long-term use of the same first filter disc 3073.

[0093] The ethanol production wastewater is pretreated by screening using a screening mechanism 3 and filter components 307. Two sets of liftable and horizontally movable filter components 307 are installed in the screening mechanism 3 to trap large particulate solid impurities in the wastewater. Because the height of the filter components 307 is easily controllable, the heights of the first filter disc 3073 and the second filter disc 3074 can be adjusted during water intake, avoiding the situation where long-term use of the same filter discs leads to clogging of the screening cylinder 2 and prevents water from flowing out.

[0094] Connection component 306 includes:

[0095] Support rod 3061 is installed on top of connecting rod 305;

[0096] The first adjusting rod 3062 is installed on the outside of the support rod 3061;

[0097] The second push rod 3063 is installed outside the first adjusting rod 3062;

[0098] The second adjusting rod 3064 is installed at the bottom of the second push rod 3063;

[0099] The first cross plate 3065 is installed at the bottom of the second adjusting rod 3064. The first cross plate 3065 is made of rubber and a first rubber strip is installed on the outside of the first cross plate 3065.

[0100] The third adjusting rod 3066 is installed at the bottom of the first cross plate 3065;

[0101] The second cross plate 3067 is installed at the bottom of the third adjusting rod 3066. The second cross plate 3067 is made of rubber and a second rubber strip is installed on the outside of the second cross plate 3067.

[0102] As the filter assembly 307 moves horizontally away from the screening cylinder 2, the second push rod 3063 is activated to its second stroke. The second push rod 3063 drives the second adjusting rod 3064, the first cross plate 3065, the third adjusting rod 3066, and the second cross plate 3067 downwards. The first cross plate 3065 gradually engages in the first cross groove 3076, and the second cross plate 3067 gradually engages in the second cross groove 3077. Subsequently, the second push rod 3063 is adjusted to reciprocate between the first and second strokes. The second push rod 3063 drives the lower first cross plate 3065 and second cross plate 3067 to move up and down. The first cross plate 3065 and second cross plate 3067 repeatedly drive the first filter disc 3073 and second filter disc 3074 to move up and down, causing the rubber-material first filter disc 3073 and second filter disc 3074 to repeatedly deform, promoting the separation of large solid particles from the first filter disc 3073 and second filter disc 3074.

[0103] By setting the connecting component 306 and the filter component 307, the contact between the connecting component 306 and the filter component 307 promotes the separation of large solid particles from the filter component 307. By setting a first filter disc 3073 and a second filter disc 3074 in the filter component 307, and forming a first cross groove 3076 in the first filter disc 3073 and a second cross groove 3077 in the second filter disc 3074, the first cross plate 3065 and the second cross plate 3067 in the connecting component 306 connect the first cross groove 3076 and the second cross groove 3077. This controls the repeated vertical deformation of the first filter disc 3073 and the second filter disc 3074, promoting the detachment of solid impurities.

[0104] The regulating mechanism 5 also includes:

[0105] The first motor housing 501 is installed outside the regulating tank 4, and the first motor is installed inside the first motor housing 501.

[0106] The first rotating shaft 502 is connected to the output end of the first motor and is rotatably connected inside the regulating tank 4.

[0107] The first outer cylinder 503 is installed outside the first rotating shaft 502. A scraper 504 is installed outside the first outer cylinder 503. The scraper 504 is made of elastic material.

[0108] Plate 505 is installed on the outside of the first outer cylinder 503. There are two plates 505, which are symmetrically arranged. Plate 505 is composed of multiple railings, and the outer surface of the multiple railings is made of adhesive material.

[0109] The second motor housing 506 is installed outside the regulating tank 4, and the second motor is installed inside the second motor housing 506;

[0110] The second rotating shaft 507 is connected to the output end of the second motor and is rotatably connected inside the regulating tank 4.

[0111] The second outer cylinder 508 is installed outside the second rotating shaft 507, and an arc-shaped plate 509 is installed on the outside of the second outer cylinder 508.

[0112] The third motor box 510 is installed outside the regulating pool 4. The third motor is installed inside the third motor box 510. The rotating column 511 is connected to the output end of the third motor. The rotating column 511 is rotatably connected inside the regulating pool 4. The rotating column 511 is made of soft rubber.

[0113] Wedge plate 512 is installed on the outside of rotating column 511. There are two wedge plates 512. In the initial state, rotating column 511, which is made of soft rubber, presses against the upper part of channel 513, blocking channel 513.

[0114] Wastewater enters the equalization tank 4 above the arc plate 509. The first motor in the first motor box 501 is turned on. The first motor drives the first rotating shaft 502, the first outer cylinder 503, the scraper 504 and the plate 505 to rotate. During the rotation, the plate 505 stirs the wastewater and the added reagents.

[0115] As the influent volume increases, the second motor in the second motor box 506 is turned on. The second motor then drives the second rotating shaft 507, the second outer cylinder 508, and the arc plate 509 to deflect, thus adjusting the direction of the wastewater flow.

[0116] After the treatment is completed, the third motor in the third motor box 510 is turned on. The third motor drives the rotating column 511 to deflect, so that the wedge plate 512 is above the channel 513. At this time, there is a gap between the wedge plate 512 and the bottom of the regulating tank 4. The wastewater flows into the channel 513 along the gap and then enters the second outlet pipe through the channel 513.

[0117] By setting up the regulating mechanism 5, the flow direction of a large amount of wastewater can be controlled by deflecting the arc plate 509 using the second motor before the wastewater enters the regulating tank 4. After the wastewater enters the regulating tank 4, the rotation of the plate 505 using the first motor can control the reagent to have a large-scale contact with the wastewater, accelerating the regulating process. After the wastewater has been regulated, the opening of the channel 513 can be controlled by rotating the rotating column 511 using the third motor, thereby discharging the wastewater.

[0118] Working principle: Before using the equipment, adjust the screening mechanism 3, then introduce the ethanol production wastewater into the screening cylinder 2, turn on the screening mechanism 3, and perform screening of the wastewater.

[0119] Before using the equipment, activate the first lifting rod 301 to its second stroke. The first lifting rod 301 drives the fixed frame 302, the slide plate 303, the first push rod 304, the connecting rod 305, the connecting assembly 306, and the filter assembly 307 to move upward. Then, activate a symmetrical set of first push rods 304. The two first push rods 304 drive the two slide plates 303 to move towards the screening cylinder 2 until the filter assembly 307 is directly above the screening cylinder 2.

[0120] Then, the first lifting rod 301 is adjusted to the initial state. The first lifting rod 301 drives the filter component 307 into the screening cylinder 2. As the wastewater enters the screening cylinder 2, the wastewater flows downward through the connecting component 306, and large solid impurities are trapped in the connecting component 306.

[0121] As the screening process proceeds, the first lifting rod 301 is adjusted to the first stroke. The first lifting rod 301 drives part of the filter component 307 upward to separate from the screening cylinder 2. At this time, the wastewater moves downward through the middle part of the filter component 307.

[0122] Adjust the first lifting rod 301 to the second stroke. The first lifting rod 301 drives the filter component 307 to completely detach from the screening cylinder 2. The filter component 307 is left to stand, and a small amount of wastewater falls into the screening cylinder 2.

[0123] As the first lifting rod 301 drives the filter assembly 307 into the screening cylinder 2, the vertical rod 3071 at the bottom of the connecting rod 305 gradually enters the groove on the side wall of the screening cylinder 2, and both the first filter disc 3073 and the second filter disc 3074 are in the screening cylinder 2. Wastewater flows downward through the first filter disc 3073 and the second filter disc 3074, and most of the large solid particles are trapped in the first filter disc 3073.

[0124] As the first lifting rod 301 drives the first filter disc 3073 upward to detach from the screening cylinder 2, the second filter disc 3074 separately intercepts large solid impurities, thus avoiding the situation where the screening cylinder 2 becomes clogged and unable to output water due to the blockage of the first filter disc 3073 caused by long-term use of the same first filter disc 3073.

[0125] Before the second batch of wastewater is introduced, the power system in the slide plate 303 is adjusted, and another set of slide plates 303 is used to drive another filter component 307 to repeat the above work to treat the second batch of wastewater.

[0126] After the screening process is completed, the wastewater treated by the screening cylinder 2 is introduced into the equalization tank 4 using the pump body 8, and the equalization mechanism 5 is turned on to adjust the pH value of the wastewater.

[0127] Wastewater enters the equalization tank 4 above the arc plate 509. The first motor in the first motor box 501 is turned on. The first motor drives the first rotating shaft 502, the first outer cylinder 503, the scraper 504 and the plate 505 to rotate. During the rotation, the plate 505 stirs the wastewater and the added reagents.

[0128] As the influent volume increases, the second motor in the second motor box 506 is turned on. The second motor then drives the second rotating shaft 507, the second outer cylinder 508, and the arc plate 509 to deflect, thus adjusting the direction of the wastewater flow.

[0129] After the treatment is completed, the third motor in the third motor box 510 is turned on. The third motor drives the rotating column 511 to deflect, so that the wedge plate 512 is in the vertical direction. At this time, there is a gap between the wedge plate 512 and the bottom of the regulating tank 4. The wastewater flows into the channel 513 along the gap, and then enters the second outlet pipe through the channel 513.

[0130] Then, using pump 8, the wastewater treated by equalization tank 4 is introduced into first processor 6, and then the wastewater treated by first processor 6 is introduced into second processor 7.

[0131] After the wastewater treatment is completed, the pump body 8 is used to introduce the wastewater treated by the second processor 7 into the equalization tank 4, and the equalization mechanism 5 is turned on to repeat the work in the equalization tank 4 and perform backflow cleaning work on the equalization tank 4.

[0132] This invention provides a process for recycling ethanol production wastewater, comprising the following steps:

[0133] S1. Before using the equipment, adjust the screening mechanism 3, then introduce the ethanol production wastewater into the screening cylinder 2, turn on the screening mechanism 3, and perform the screening of the wastewater.

[0134] S2. Using pump body 8, the wastewater treated by screening tube 2 is introduced into equalization tank 4, and the equalization mechanism 5 is turned on to adjust the pH value of the wastewater.

[0135] S3. Using pump body 8, the wastewater treated by equalization tank 4 is introduced into first processor 6, and then the wastewater treated by first processor 6 is introduced into second processor 7.

[0136] S4. After the wastewater treatment is completed, the pump body 8 is used to introduce the wastewater treated by the second processor 7 into the equalization tank 4, and the equalization mechanism 5 is turned on to perform backflow cleaning work on the equalization tank 4.
