Description

Technical Field

[0001] This utility model relates to the field of saturator cleaning wastewater treatment technology, specifically a saturator cleaning wastewater treatment device. Background Technology

[0002] During the coking process, coke oven gas carries a large amount of ammonia-containing substances. The coke oven gas ammonium sulfate process, a key environmental protection and resource recovery link in the coking industry chain, primarily removes ammonia from the coke oven gas and converts it into ammonium sulfate. This not only avoids corrosion of downstream equipment by ammonia-containing gas and reduces environmental pollution risks, but also transforms ammonia resources into economically valuable fertilizer products, achieving resource recycling and effectively improving the economic and environmental benefits of coking enterprises. Therefore, during normal operation of the saturator, acid and water cleaning is required every 24 hours to remove internal wall crystals and stabilize saturator resistance. Using domestic water for cleaning would consume a large amount of water; therefore, ammonia stripping wastewater is used to clean the saturator to improve cleaning efficiency, reduce energy consumption, decrease sulfuric acid usage, extend the saturator's service life, and ensure continuous and stable operation of the ammonium sulfate process.

[0003] Since suspended solids, tar, and hydrocarbon oils contained in ammonia stripping wastewater can adhere to and clog the nozzles and packing pores of the saturator, resulting in uneven gas-liquid distribution, and oily impurities covering the metal surface, causing corrosion damage to the saturator, we propose a saturator cleaning wastewater treatment device.

[0031] In this implementation plan, the above-mentioned technology ensures that the threaded cylinder 17 and the separating cylinder 9 rotate at a stable high speed.

[0032] Furthermore:

[0033] In an optional embodiment, the transmission tube 8 is connected to the threaded cylinder 17, and the threaded cylinder 17 is connected to the separation cylinder 9.

[0034] In this implementation plan: the ammonia-containing wastewater can be transported to the interior of the separation cylinder 9 through the transmission pipe 8.

[0042] Furthermore:

[0043] In an optional embodiment, the lid 3 is further provided with:

[0044] A water pump 7 is fixedly installed on the upper right side of the bucket cover 3. A first three-control valve 4 is fixedly installed at the input end of the water pump 7, and a liquid extraction pipe 11 is installed at the input end of the first three-control valve 4. A second three-control valve 5 is fixedly installed at the output end of the water pump 7, and a connecting pipe 6 is fixedly installed at the output end of the second three-control valve 5. A rotary joint 12 is threadedly installed at the bottom of the connecting pipe 6. A transmission pipe 8 is movably connected to the connecting pipe 6 through the rotary joint 12, and the transmission pipe 8 is connected to the connecting pipe 6 through the rotary joint 12. The liquid extraction pipe 11 passes through the inside of the bucket cover 3 and is connected to the treatment bucket 1.

[0045] In this implementation plan: by setting the first three-control valve 4 and the second three-control valve 5, the ammonia stripping wastewater from the ammonia stripping tower is pumped into the separation cylinder 9 for filtration, and the treated ammonia stripping wastewater inside the treatment tank 1 is pumped into the saturator.

[0046] Working Principle: When using this saturator to clean the wastewater treatment device, firstly, connect the other input port of the first three-control valve 4 to the sewage pipe of the ammonia stripping tower, and connect the other output port of the second three-control valve 5 to the gas inlet of the saturator. Then, control the motor 16 to turn on via the controller, driving the first bevel gear 13 to rotate. This, in turn, drives the transmission pipe 8 and the threaded cylinder 17 and separation cylinder 9 below it to rotate at high speed via the second bevel gear 15. When the saturator needs cleaning, control the water pump 7 to turn on via the controller, pumping the ammonia stripping wastewater from the ammonia stripping tower through the second three-control valve 5, connecting pipe 6, and transmission pipe 8 into the separation cylinder 9. The ammonia stripping wastewater contacts the filter membrane 18 through the perforated holes 19. Under the centrifugal force of high-speed rotation, the ammonia stripping wastewater passes through the filter membrane 18 and enters the treatment tank 1, thus filtering out impurities and oil stains. Next, a certain amount of ammonia stripping wastewater is pumped into the separation cylinder 9. After filtration, the controller controls the... The first three-control valve 4 and the second three-control valve 5 are controlled. At this time, the water pump 7 works again and can extract the filtered ammonia-eating wastewater from the treatment tank 1 through the liquid extraction pipe 11. It is then transported to the saturator through the other output port of the second three-control valve 5 to clean the saturator. After the wastewater treatment device finishes working, the controller can control the electric push rod 10 to push the tank cover 3 upward and push the separation cylinder 9 out of the treatment tank 1 for cleaning. Finally, the first three-control valve 4 (model: LDBAE) and the second three-control valve (5) (model: LDBAE) are existing technologies. They adopt a rotary angle electric actuator, which is powered by AC220V, AC380V or DC24V power supply voltage. It can accept the (4-20mA) current signal input from the industrial automation instrument control system to control the operation and realize the proportional adjustment or two-position switching control of the process medium. This is the working principle of the saturator cleaning wastewater treatment device.
