Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a coking wastewater treatment device. Background Art

[0002] Coking wastewater is a typical wastewater containing aromatic and heterocyclic compounds. Phenolic compounds are the primary organic pollutants, accounting for over half of the total, along with polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen, and sulfur. Inorganic pollutants primarily include hydrides, hydrosulfides, sulfides, and ammonium salts, along with polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen, and sulfur. Coking wastewater is toxic and hazardous, with high concentrations, making it challenging to treat. This is especially true for wastewater that has not been treated for dephenolization and oil removal through ammonia distillation. The phenol, NH₃-N, and oil contents are high, making treatment complex and costly. Furthermore, the final effluent COD, NH₃-N, and oil levels often fail to meet discharge standards. Therefore, the large-scale discharge of coking wastewater not only causes severe environmental pollution but also poses a direct threat to human health. Many of these substances are not only difficult to biodegrade but are also direct or indirect carcinogens.

[0003] In the existing technology, coking wastewater needs to be filtered to remove internal impurities and oil stains. During use, the filter components of conventional coking wastewater treatment devices are easily clogged and need to be regularly shut down for cleaning or replacement, which reduces work efficiency. In addition, the precipitated impurities are easy to clog the slag discharge valve, and the filtered oil stains need to be shut down for cleaning, which is very inconvenient to use.

[0023] Specifically, the cleaning mechanism 12 includes a transmission rod 121, a bearing 122, a first fastening assembly 123, a turbine blade 124, a second fastening assembly 125 and a scraper 126. The transmission rod 121 is mounted on the left and right spoilers 11 through the bearing 122. The turbine blade 124 is mounted on the left end of the transmission rod 121 through the first fastening assembly 123. The scraper 126 is mounted on the right end of the transmission rod 121 through the second fastening assembly 125, and the right side of the scraper 126 is movably fitted with the left side of the oil filter membrane assembly 9.

[0024] In this embodiment, the turbine blades 124 are driven to rotate by the coking wastewater flowing into the first circular sleeve 3 through the water inlet pipe 5, so that the turbine blades 124 drive the transmission rod 121 to rotate in the bearing 122, and the transmission rod 121 drives the scraper 126 to rotate. The scraper 126 scrapes off the impurities on the left side of the oil filter membrane assembly 9, effectively preventing the oil filter membrane assembly 9 from being blocked.

[0025] Specifically, the first fastening assembly 123 includes a sleeve 15 and a locking bolt 16. The sleeve 15 is sleeved on the transmission rod 121, and the sleeve 15 is locked and fixed to the transmission rod 121 by the locking bolt 16. The second fastening assembly 125 has the same structure as the first fastening assembly 123.

[0026] In this embodiment, the locking bolt 16 makes the structure between the sleeve 15 and the transmission rod 121 detachable, thereby facilitating the disassembly and assembly of the turbine blade 124. The right side of the turbine blade 124 is fixedly connected to the left side of the sleeve 15. Similarly, the second fastening assembly 125 facilitates the disassembly and assembly between the scraper 126 and the transmission rod 121.

[0027] Specifically, the slag discharge mechanism 13 includes a spiral feeding rod 131 and a slag discharge valve 132. The spiral feeding rod 131 is fixedly installed on the lower inner wall of the box body 1, and the left and right ends of the spiral feeding rod 131 are both arranged on the outside of the left and right side walls of the box body 1. The upper surface of the spiral feeding rod 131 is an open structure, and the slag discharge valve 132 is installed on the left end of the spiral feeding rod 131.

[0028] In this embodiment, the upper side wall of the spiral feeding rod 131 is an open structure, and impurities will fall into the spiral feeding rod 131. The electric spiral feeding rod 131 drives the impurities to move to the left, opens the slag discharge valve 132, and the impurities are discharged through the slag discharge valve 132.

[0029] Specifically, the oil discharge mechanism 14 includes an extraction component 141, a conduit 142, an oil collecting pipe 143 and an oil inlet hole 144. The extraction component 141 is installed on the upper surface of the box body 1. The extraction component 141 is connected to the oil collecting pipe 143 through the conduit 142. The oil collecting pipe 143 is fixedly installed on the upper inner wall of the box body 1. The front and rear side walls of the oil collecting pipe 143 are evenly provided with oil inlet holes 144 on the left and right near the upper position.

[0030] In this embodiment, the extraction component 141 extracts liquid from the oil collecting pipe 143 through the conduit 142, and the oil holes 144 on the front and rear side walls of the oil collecting pipe 143 allow the oil floating on the surface of the coking wastewater to be sucked in, thereby achieving the effect of oil drainage.

[0031] Specifically, guide plates 17 are obliquely installed on the front and rear inner walls of the box body 1 corresponding to the slag discharge mechanism 13 and the oil discharge mechanism 14 .

[0032] In this embodiment, the lower front and rear guide plates 17 allow impurities to flow accurately into the spiral feeding rod 131 , and the upper front and rear guide plates 17 allow oil to flow to the oil inlet holes 144 on the front and rear side walls of the oil collecting pipe 143 .

[0033] Specifically, an observation window 18 is fixedly embedded on the left side wall of the box body 1 corresponding to the oil discharge mechanism 14.

[0034] In this embodiment, the observation window 18 can be used to check the amount of oil floating on the surface of the coking wastewater on the upper side of the box body 1, which is beneficial for immediate oil drainage.

[0035] When in use, the water inlet pipe 5 is connected to the external coking wastewater pipe, and the external coking wastewater flows into the first circular sleeve 3, and then flows into the box body 1 through the first circular sleeve 3. The coking wastewater is decelerated by the two spoilers 11, and the impurities in the coking wastewater can be better precipitated downward, and the oil in the coking wastewater is better floated upward. The impurities and oil in the coking wastewater are filtered by the oil filter membrane component 9. The filtered coking wastewater flows into the second circular sleeve 7 and is then discharged through the drain valve 10. When the coking wastewater enters the first circular sleeve 3, it drives the turbine blades 124 in the cleaning mechanism 12 to rotate, so that the turbine blades 124 drive the transmission rod 121 to rotate in the bearing 122, and the transmission rod 121 drives the scraper 126 to rotate. The scraper 126 scrapes off the impurities on the left side of the oil filter membrane assembly 9, effectively preventing the oil filter membrane assembly 9 from being blocked, and the extraction component 141 in the oil discharge mechanism 14 is used to extract liquid from the oil collecting pipe 143 through the conduit 142. The oil holes 144 on the front and rear side walls of the oil collecting pipe 143 allow the oil floating on the upper surface of the coking wastewater to be sucked in, thereby achieving the effect of oil discharge. After the treatment is completed, the electric screw feeding rod 131 in the slag discharge mechanism 13 drives the impurities falling into the screw feeding rod 131 to move to the left, and the slag discharge valve 132 is opened. The impurities are discharged through the slag discharge valve 132, which can quickly discharge the impurities precipitated in the box body 1, avoid the situation of slag discharge problems, improve work efficiency, and have strong practicality.

[0036] To sum up, the coking wastewater treatment device can effectively filter impurities and oil in coking wastewater, and increase the cleaning function of the oil filter membrane component 9, extend the service life, improve work efficiency, and can quickly discharge impurities to avoid blockage. At the same time, it can discharge oil without stopping the machine, and is highly practical.
