Description

Technical Field

[0001] The present invention relates to the technical field of blue carbon wastewater filtration, and in particular to a treatment device for blue carbon wastewater filtration. Background Art

[0002] Semi-coke is a new type of coal conversion product. Due to its low price and advantages such as high fixed carbon, high specific resistivity and high chemical activity, it is widely used in industries such as calcium carbide, ferroalloy, fertilizer gasification, blast furnace injection and civilian clean coal manufacturing. Semi-coke wastewater is wastewater generated during the medium-low temperature dry distillation of coal (about 650°C), mainly from circulating water for cooling and washing coal gas and separated water in the chemical production process. Semi-coke is a low-temperature dry distillation, and the amount of tar produced during the production process is large, and there are many low-molecular organic matters. Therefore, the wastewater contains a large amount of pollutants that have not been oxidized by high temperature, and its concentration is about 10 times higher than that of coking wastewater, so it is more difficult to treat than coking wastewater. Since the lignite wastewater may contain a large amount of suspended matter (coal slag and coal slime, etc.), it will affect the subsequent biochemical or biological treatment of the lignite wastewater. At the same time, the suspended matter (coal slag and coal slime, etc.) in the lignite wastewater can be used as a heating raw material. However, after the suspended matter (coal slag and coal slime, etc.) is separated from the lignite wastewater, the suspended matter (coal slag and coal slime, etc.) will contain an oil-water mixture. Therefore, after the suspended matter (coal slag and coal slime, etc.) is separated from the lignite wastewater, it is necessary to manually use transfer equipment to transfer the suspended matter (coal slag and coal slime, etc.) separated from the lignite wastewater to an external drying equipment for solid-liquid separation of the suspended matter (coal slag and coal slime, etc.), which is cumbersome to operate. Summary of the invention

[0003] In order to overcome the disadvantages that the semi-coke wastewater may contain a large amount of suspended matter, which affects the subsequent biochemical or biological treatment of the semi-coke wastewater, and after the suspended matter is separated from the semi-coke wastewater, the suspended matter will contain an oil-water mixture, and the suspended matter needs to be manually transferred to a drying equipment for solid-liquid separation, which is cumbersome to operate, a treatment equipment is provided, which can filter out the suspended matter and oil in the semi-coke wastewater, and then dry the suspended matter, so that the dried suspended matter can be manually made into coal cakes for use as heating raw materials.

Compared with the horizontal filter plate, filtering the lignite wastewater through the filter cartridge can not only prevent the filter holes from being blocked by a large amount of large-particle suspended matter, thereby reducing the filtering effect of the lignite wastewater, but also utilize the filter cartridge to continuously pass through the lignite wastewater to impact and fall off the large-particle suspended matter attached to the filter cartridge, thereby ensuring the sustainable filtering effect of the lignite wastewater.

[0016] The treatment equipment for filtering blue carbon wastewater obtained by the above design of the present invention removes the suspended matter gathered at the bottom of the cavity one through the continuously rotating spiral plate, thereby avoiding the accumulation of excessive suspended matter at the bottom of the cavity one, which affects the filtering effect of the filter cartridge and the filter cloth.

[0017] The treatment equipment for filtering blue carbon wastewater obtained by the above design of the present invention heats the suspended matter through the heating plate, so that the oil-water mixture on the suspended matter evaporates and turns into steam, which is convenient for the operator to subsequently make the dried suspended matter into briquettes for use as heating raw materials, and absorbs the oil molecules in the steam through the oil-absorbing felt, and then discharges the steam containing water molecules into cavity one to mix it with the blue carbon wastewater, eliminating the step of manually transporting the suspended matter to the drying equipment for solid-liquid separation, thereby saving a lot of time and cost.

[0018] The treatment equipment for filtering blue carbon wastewater obtained by the above design of the present invention conveys high-pressure steam to the curved pipe through the curved part of the reflux pipe, and at the same time, the water molecule vapor contained in the high-pressure steam is dissolved in the blue carbon wastewater, and the small particle suspended matter and oil attached to the filter cloth are impacted and removed by the bubbles generated by the high-pressure steam in the blue carbon wastewater, so as to avoid a large amount of small particle suspended matter and oil attached to the filter cloth, resulting in a decrease in the filtering effect of the filter cloth, and the high-pressure steam is integrated with the filtered blue carbon wastewater, and there is no need to filter it through the filter cloth again, so the filtering burden of the filter cloth is reduced and useless work is not done.

[0028] Furthermore, in order to prevent the filter cloth 9 from being broken or deformed by the impact of the continuously flowing lignite wastewater, a support frame is provided on the outside of each filter cloth 9, and the filter cloth 9 can also be an activated carbon filter layer or other material that can purify the lignite wastewater.

[0029] Furthermore, in order to prevent the oil-water mixture and steam from being discharged from the gap between the receiving plate 205 and the mounting plate 201 , a piston-type rubber strip is provided between the receiving plate 205 and the mounting plate 201 .

[0030] The working steps of this embodiment are: The following rotations are from front to back, from top to bottom, and from right to left. The first step is to place the treatment equipment for blue carbon wastewater filtration at the required location when using it; In the second step, the operator connects an external power supply to the motor 4, the electric push rod 1 202, the heating plate 206 and the electric push rod 2 302, and connects an external blue carbon wastewater conveying device to the water inlet pipe 104. Since the blue carbon wastewater may contain a large amount of suspended matter, it will affect the subsequent biochemical or biological treatment of the blue carbon wastewater, and after the suspended matter is separated from the blue carbon wastewater, the suspended matter will contain an oil-water mixture, and the suspended matter needs to be manually transported to the drying equipment for solid-liquid separation, which is cumbersome to operate. Therefore, the external equipment is controlled to convey the blue carbon wastewater into the water inlet pipe 104. After the blue carbon wastewater enters the U-shaped tube 103, it will be diverted into the two cavities 13a of the filter box 3. After entering the cavity 13a, the blue carbon wastewater will pass through the filter cartridge 7 and pass through the filter cartridge 7. The large suspended particles contained in the semi-coal wastewater are filtered and intercepted on the outside of the filter cartridge 7. However, since the semi-coal wastewater continuously impacts the same position of the filter cartridge 7, the filter holes at that position of the filter cartridge 7 are easily blocked, thereby affecting the normal filtration of the semi-coal wastewater. Therefore, during the continuous flow of the semi-coal wastewater, the output shaft of the motor 4 is controlled to rotate clockwise to drive the circular plate 5, the ring plate 6, the filter cartridge 7, the spiral plate 8 and the filter cloth 9 to rotate together. The semi-coal wastewater is impacted by the continuously rotating filter cartridge 7, so that the position where the semi-coal wastewater impacts the filter cartridge 7 continuously changes, thereby preventing the semi-coal wastewater from continuously passing through the same position of the filter cartridge 7 and blocking the filter holes at that position of the filter cartridge 7, thereby ensuring the filtering effect of the semi-coal wastewater. When the lignite wastewater flows into the curved pipe 101 from the outlet of the cavity 3a, the small suspended particles in the lignite wastewater are filtered by the filter cloth 9, and the small suspended particles in the lignite wastewater are filtered out, and the oil in the lignite wastewater is intercepted at the same time. At this time, the filter cloth 9 filters the lignite wastewater, which not only achieves the effect of removing small suspended particles, but also limits the flow of the flowing lignite wastewater, reduces the flow rate of the lignite wastewater, so that the small suspended particles intercepted by the filter cloth 9 will settle at the bottom of the cavity 3a, and the lignite wastewater filtered by the filter cloth 9 will enter the curved pipe 101, and then flow into the transition box 1. When the transition box 1 is filled with the filtered lignite wastewater, the operator performs biochemical or biological treatment on the lignite wastewater in the transition box 1 until the lignite wastewater treatment is completed, and then it is extracted from the transition box 1.

[0031] At the same time, it is necessary to control the flow rate of the semi-coal wastewater entering the two cavities 3a, so that the water level of the semi-coal wastewater in the two cavities 3a is always kept below the arc-shaped opening 3c, and prevent the semi-coal wastewater in the cavity 3a from flowing out of the arc-shaped opening 3c; Because the water level of the semi-coal wastewater is always maintained below the arc-shaped opening 3c, half of the filter cartridge 7 is located in the semi-coal wastewater, and as the filter cartridge 7 continues to rotate, the part of the filter cartridge 7 with large suspended particles attached to it will first enter the semi-coal wastewater, and then come out of the semi-coal wastewater. Such a continuous cycle can not only change the impacted position of the filter cartridge 7, but also utilize the collision between the large suspended particles on the filter cartridge 7 and the semi-coal wastewater to force the large suspended particles attached to the filter holes of the filter cartridge 7 to automatically detach and gradually settle down at the bottom of the cavity 3a. Compared with the horizontal filter plate, filtering the semi-coal wastewater through the filter cartridge 7 can not only prevent a large number of large suspended particles from clogging the filter holes, resulting in a decrease in the filtering effect of the semi-coal wastewater, but also utilize the filter cartridge 7 to continuously pass through the semi-coal wastewater to impact and fall off the large suspended particles attached to the filter cartridge 7, without stopping the machine to clean the filter cartridge 7, thereby ensuring the sustainable filtering effect of the semi-coal wastewater. In the process that the suspended matter in the blue carbon wastewater gradually gathers at the bottom of the cavity 3a, the continuously rotating spiral plate 8 will transport the suspended matter gathered at the bottom of the cavity 3a to the arc-shaped mouth 3c, so that the suspended matter can be separated from the blue carbon wastewater, enter the arc-shaped mouth 3c, and then come to the receiving plate 205. In this way, the suspended matter gathered at the bottom of the cavity 3a can be removed by the continuously rotating spiral plate 8, avoiding the accumulation of too much suspended matter at the bottom of the cavity 3a, which will affect the filtering effect of the filter cartridge 7 and the filter cloth 9.

[0032] In the third step, when a large amount of suspended matter is accumulated on the receiving plate 205, since the suspended matter just separated from the blue carbon wastewater contains an oil-water mixture, the suspended matter needs to be dried to separate the oil-water mixture contained therein, so as to facilitate the subsequent production of the suspended matter into coal cakes for use as heating raw materials. Therefore, the telescopic parts of the two electric push rods 302 are controlled to be pushed out, driving the arc plate 303, the slide rod 304, the spring 305 and the sealing plate 306 to move downward, and the telescopic tube 402 is automatically stretched. At this time, because the sealing plate 306 is in contact with the inner wall of the cavity 3b, and the inner wall of the cavity 3b is a downwardly inclined slope, the sealing plate 306 will be pushed toward the arc plate 303 by the inner wall of the cavity 3b during the movement. The sealing plate 306 is pushed in the direction, forcing the sealing plate 306 to drive the multiple sliding rods 304 to slide in the multiple grooves 303a, so that the multiple springs 305 are compressed until the sealing plate 306 blocks the arc-shaped opening 3c, and then the heating plate 206 on the receiving plate 205 is controlled to start heating. As the temperature gradually rises, the suspended matter is dried and dehydrated, and the oil-water mixture on the suspended matter evaporates into steam under the action of high temperature and gathers in the cavity 2 3b. After the heating plate 206 rises to a certain temperature, it stops heating and maintains the current temperature. The suspended matter on the receiving plate 205 is continuously heated for a period of time. The oil-water mixture on the suspended matter will completely turn into steam under the action of high temperature, and then the heating plate 206 is controlled to stop heating; At the same time, during the continuous heating process of the heating plate 206, a large amount of steam will gradually float upwards and then be restricted in the second cavity 3b by the fixed plate 301. Then, the oil molecules contained in the steam will be absorbed by the annular oil-absorbing felt 307, and the water molecules will be filled in the second cavity 3b. When the heating plate 206 stops heating, the oil molecules in the steam in the second cavity 3b are all absorbed by the oil-absorbing felt 307, and only water molecules are left in the steam. When the heating plate 206 stops heating, the two electric push rods 302 are controlled to contract, driving the connected components to move upward together, so that the sealing plate 306 no longer blocks the arc-shaped opening 3c, making the cavity 3b The steam containing only water molecules in cavity 2 3b flows from the arc-shaped mouth 3c into cavity 1 3a and mixes with the semi-coke wastewater in cavity 1 3a. In this way, the suspended matter is heated by the heating plate 206 to evaporate the oil-water mixture on the suspended matter into steam, which makes it convenient for the operator to subsequently make the dried suspended matter into briquettes for use as heating raw materials, and absorb the oil molecules in the steam through the oil-absorbing felt 307, and then discharge the steam containing water molecules into cavity 1 3a to mix with the semi-coke wastewater, thereby eliminating the need to manually transport the suspended matter to the drying equipment for solid-liquid separation, thereby saving a lot of time and cost.

[0033] It should be noted that the operator regularly takes out the oil-absorbing felt 307 in the cavity 2 3b for replacement to ensure that the oil-absorbing felt 307 can continue to absorb the oil molecules in the steam.

[0037] The collection unit includes a collection box 406 and a drawer 407; a slag discharge port 201c is respectively provided on the front side and the rear side of the mounting plate 201; a collection box 406 is respectively fixedly connected to the front side and the rear side of the mounting plate 201, and the two collection boxes 406 are respectively located below a slag discharge port 201c; a drawer 407 is detachably connected to each collection box 406.

[0038] The working principle of this embodiment is: In step 3 of embodiment 1, the operator first connects an external power supply to the vacuum pump 401. Since the steam discharged from the cavity 2 3b into the cavity 1 3a will float inside the cavity 1 3a and will not be quickly dissolved in the semi-coal wastewater, and even if the steam merges with the semi-coal wastewater entering the cavity 1 3a, it needs to be filtered again by the filter cloth 9. This not only prevents the steam from being quickly dissolved in the semi-coal wastewater, but also increases the filtering burden of the filter cloth 9, which is useless. Therefore, when the oil-water mixture on the suspended matter is completely heated and turned into steam, the vacuum pump 401 is controlled to be turned on, and the semi-coal wastewater is filtered out through the telescopic tube 4 02 continues to transport compressed gas into cavity 2 3b, pressurizes the steam in cavity 2 3b, so that the steam and compressed gas are mixed to form high-pressure steam. When the air pressure in cavity 2 3b is greater than the water pressure of the semi-coal wastewater in the elbow 101, the one-way valve in the return pipe 403 is forced to open, and the high-pressure steam is transported to the elbow 101. At this time, because the curved portion 403a of the return pipe 403 is inclined in the elbow 101 toward the filter cloth 9, the high-pressure steam ejected from the curved portion 403a contacts the semi-coal wastewater in the elbow 101, and the water molecules in the high-pressure steam are The compressed air will dissolve in the semi-coke wastewater, and the bubbles generated by the high-pressure steam in the semi-coke wastewater will impact the part of the filter cloth 9, so that the small suspended particles and oil attached to the other side of the filter cloth 9 will be impacted and fall off, and the filter cloth 9 will rotate with the filter cartridge 7, so that the entire filter cloth 9 will be impacted by the bubbles formed by the compressed gas, so that the small suspended particles and oil attached to the filter cloth 9 will fall off completely. After the vacuum pump 401 has worked for a period of time, the vacuum pump 401 is controlled to be turned off. At this time, the air pressure in the cavity 2 3b is lower than the water pressure in the elbow 101. Under the action of the water pressure, the elbow is forced to The one-way valve in 101 is closed, so that the high-pressure steam is transported to the curved pipe 101 through the curved portion 403a of the return pipe 403, so that the water molecules contained in the high-pressure steam are dissolved in the semi-coke wastewater, and the small particles of suspended matter and oil attached to the filter cloth 9 are impacted and removed by the bubbles generated by the high-pressure steam in the semi-coke wastewater, thereby avoiding a large amount of small particles of suspended matter and oil attached to the filter cloth 9, which would reduce the filtering effect of the filter cloth 9, and the high-pressure steam is integrated with the filtered semi-coke wastewater, so it does not need to be filtered through the filter cloth 9 again, which reduces the filtering burden of the filter cloth 9 and does not do useless work.

[0039] When the steam in the cavity 2 3b is discharged into the elbow 101, the suspended matter will stick to each other during the process of drying the oil-water mixture. After the oil-water mixture is completely turned into steam, the suspended matter will become blocks and adhere to the receiving plate 205. It is difficult for the operator to remove the block suspended matter on the receiving plate 205. Therefore, the telescopic parts of the two electric push rods 202 are controlled to contract, driving the connecting block 203, the round rod 204, the receiving plate 205, the heating plate 206, the sliding column 404 and the scraper 405 to move downward together. The two round rods 204 move downward in the corresponding slide grooves 201a, and the two sliding columns 404 move in the corresponding inclined grooves 201b. When the two sliding columns 404 move, they will drive the two scrapers 405 to move to the opposite sides on the receiving plate 205. The suspended matter agglomerated on the receiving plate 205 is pushed to move together. When the round rod 204 moves to the lowermost end of the chute 201a, the slide column 404 also moves to the end of the chute 201b. At this time, the scraper 405 contacts the inner wall of the mounting plate 201, and the suspended matter in block shape on the receiving plate 205 is discharged from the slag discharge port 201c into the drawer 407 of the collecting box 406. Then the telescopic parts of the two electric push rods 202 are controlled to be pushed out, driving the connected parts to reset upwards. The telescopic parts of the two electric push rods 202 are also contracted, driving the connected parts to reset. In this way, the suspended matter in block shape on the receiving plate 205 is pushed into the drawer 407 for collection by the scraper 405. The operator does not need to spend time and effort to remove the suspended matter in block shape on the receiving plate 205, thereby reducing the burden of labor.
