Description

Technical Field

[0001] The utility model belongs to the technical field of industrial wastewater treatment, and specifically relates to a treatment device for industrial circulating water. Background Art

[0002] Industrial circulating water is mainly used in cooling water systems, so it is also called circulating cooling water. Industrial circulating water is mainly used in cooling water systems, so it is also called circulating cooling water, because industrial cooling water accounts for more than 90% of the total water consumption.

[0003] There are two types of circulating cooling water: closed type (sealed type) and open type. In a closed cooling water system, the cooling water is not exposed to the air, the water loss is very small, and the content of various minerals and ions in the water generally does not change. This type of cooling water system is suitable for use in areas with high environmental requirements.

[0004] Open circulating water systems are common in industrial refrigeration. Because of their open settings, daily maintenance and disassembly are relatively convenient. However, in this type of cooling water system, water recooling is carried out through a cooling tower, so the cooling water will come into contact with the air during the recirculation process. Part of the water will continue to evaporate and be lost when passing through the cooling tower, so the content of various minerals and ions in the water will continue to be concentrated and increased. After the accumulation of time, minerals and ions will gather together, thus generating micro-particles in the circulating water. The micro-particles can adhere to the walls of each heat exchange tube. In this case, the heat exchange efficiency will be reduced and the corrosion rate of the pipeline will be accelerated.

[0005] Therefore, in order to ensure the long-term and efficient operation of the open circulating water system, it is necessary to remove micro-particles in the circulating pipeline, discharge the water into the sedimentation tank, add mineral precipitation reagents to remove minerals in the circulating water, and use the circulating pump to extract the upper water of the sedimentation tank and pass it into the ion exchange osmosis membrane equipment, and then remove ions through the ion exchange osmosis membrane equipment, and finally the water will continue to be put into use and circulation.

[0006] For the removal of micro-particles, molecular sieve adsorption particles are currently used to achieve this. Since molecular sieve adsorption particles are used for a long time in the removal of micro-particles, they need to be replaced regularly to ensure efficient removal of micro-particles. Therefore, it is necessary to provide a method for removing micro-particles with good effect, which is convenient for replacing adsorption and filtration consumables and ensures continuous removal of micro-particles in water during replacement.

[0029] The right end flange of each discharge pipe 6 is connected to a solenoid valve 7, and the discharge end of the solenoid valve 7 is connected to a filter mechanism, which is used to absorb micro-particles of sewage discharged into the filter mechanism and can quickly escape from the filter mechanism inside the filter mechanism;

[0030] One end of the filtering mechanism is connected to the connecting pipe 26 through a connecting hose 102. The connecting hose 102 is a rubber hose with steel wire inner ribs. The connecting hose 102 can be bent when the filtering mechanism is removed, and the connection between the filtering mechanism and the connecting pipe 26 is ensured. The right end of the connecting pipe 26 is connected to the electromagnetic valve 25, and the discharge end of the electromagnetic valve 25 is connected to the dosing stirring mechanism. The dosing stirring mechanism is used to add mineral precipitation reagents to the sewage discharged into it, stir it, and then discharge it into the sedimentation tank.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The filtering mechanism includes an access pipe 8 connected by a flange to the discharge end of the solenoid valve 7, a filter cartridge 9 is integrally arranged at the right end of the access pipe 8, a gland 10 is tightly pressed at the right end of the filter cartridge 9, a sealing ring 12 is bonded to the outer edge of the left end of the gland 10 with a waterproof resin adhesive, the sealing ring 12 is made of rubber, a receiving pipe 11 is integrally arranged at the center of the gland 10, a rotating ring 14 is screwed at the left end of the gland 10, a support ring 13 is integrally arranged on the rotating ring 14 and the support ring 13 is located in the filter cartridge 9, a filter screen plate 15 is fused in the support ring 13, and the filter hole diameter of the filter screen plate 15 is 0.4 mm;

[0032] The support ring 13 is screwed with an outer support cylinder 16, the outer wall of the outer support cylinder 16 slides in contact with the inner wall of the filter cylinder 9, and a through hole 17 is evenly arranged at the center of the left end of the outer support cylinder 16. The inner diameter of the through hole 17 is 0.4 mm. A filter mechanism is installed in the outer support cylinder 16, and the filter mechanism is used to absorb micro particles in sewage;

[0033] A support plate 20 is bolted to the middle of the base 1, and a hydraulic cylinder 21 is bolted to the front and rear of the support plate 20 evenly. The top rod of the hydraulic cylinder 21 passes through the support plate 20 and is bolted to the connecting plate 22. The top of the connecting plate 22 is welded to the bottom of the outlet pipe 11. The right end of the outlet pipe 11 is interference fit into the connecting hose 102 and is tightened by a throat clamp.

[0034] Among them, the inlet and outlet liquid ends of the hydraulic cylinder 21 are connected to the inlet and outlet liquid ends on one side of the external mechanical reversing valve through a pressure oil pipe, and the inlet and outlet liquid ends on the other side of the mechanical reversing valve are connected to the inlet and outlet liquid ends of the external hydraulic pump through a pressure oil pipe; and when the push rod of the hydraulic cylinder 21 is extended to the longest state, the sealing ring 12 is pressed against the right end of the filter cartridge 9 by the pressure cover 10, and when the push rod of the hydraulic cylinder 21 is retracted to the shortest state, the filtering mechanism can be completely brought out of the filter cartridge 9 and is 20 cm away from the right end of the filter cartridge 9.

[0035] Therefore, by operating each mechanical reversing valve, the extension and retraction of the push rod of the hydraulic cylinder 21 is controlled, thereby controlling the filter mechanism to escape from the filter cartridge 9 or the pressure cover 10 to press the sealing ring 12 against the right end of the filter cartridge 9 .

[0036] See also Figure 3 and Figure 4 The filtering mechanism includes a cladding 18 which is slidably inserted into the outer support tube 16. The cladding 18 is a non-woven fabric. The pore diameter of the cladding 18 is 0.2 mm. The cladding 18 is tightly filled with a filter column 19. The filter column 19 is a 4A grade molecular sieve particle with a particle diameter of 1 mm.

[0037] Therefore, when water passes through the through holes 17 and the cladding 18, the micro-particles can be effectively absorbed by the filter column 19, and then the water is discharged to the outlet pipe 11 through the filter plate 15, ensuring a better removal capability of the micro-particles.

[0038] See also Figure 1 and Figure 2 The tops of the access pipe 8 and the access pipe 11 are both sealed and screwed with an electronic water pressure gauge 101. By observing the pressure values ​​displayed by the electronic water pressure gauges 101 installed on the access pipe 8 and the access pipe 11, if it is known that under normal circumstances, the pressure value in the access pipe 11 is lower than the standard threshold range ST of the pressure value of the contact pipe 8, and the actual pressure difference between the two is greater than the standard threshold range, the filter mechanism can be replaced.

[0039] During the process of replacing the filter mechanism, the top rod of the hydraulic cylinder 21 is controlled to retract, driving the filter mechanism to escape from the filter cartridge 9, unscrewing the outer support cylinder 16 out of the support ring 13, and pouring out the cladding 18 and the filter column 19 in the outer support cylinder 16. During this process, the support ring 13 and the filter screen 15 can also be replaced, and a new cladding 18 and a filter column 19 are loaded into the outer support cylinder 16, and the outer support cylinder 16 is tightened on the support ring 13 again, and the top rod of the hydraulic cylinder 21 is controlled to extend, driving the filter mechanism to reinsert the filter cartridge 9.

[0040] During the process of replacing the filter mechanism, it is only necessary to close the solenoid valve 1 7 and the solenoid valve 2 25 on both sides of the filter mechanism that needs to be replaced, and keep the solenoid valve 1 7 and the solenoid valve 2 25 on both sides of the remaining filter mechanisms open, so that during the process of replacing the filter mechanism, the remaining filter mechanisms can continue to remove micro-particles.

[0041] It is worth noting that the electric control input terminals of the solenoid valve 1 7 and the solenoid valve 2 25 are connected to the electric control terminals of the external PLC through cables, and the external PLC executes the control of the opening and closing valve operations of each group of solenoid valves 1 7 and solenoid valves 2 25.

[0042] See also Figure 1 , Figure 2 and Figure 3 The dosing stirring mechanism includes a stirring drum 23 arranged on the right side of the base 1, and a discharge pipe 24 is evenly welded to the front and back of the left side of the stirring drum 23, and the discharge pipe 24 is connected to the stirring drum 23, and the left end flange of the discharge pipe 24 is connected to the discharge end of the electromagnetic valve 25;

[0043] A discharge pipe 27 is integrally provided at the lower rear side of the mixing drum 23, and a drain pipe 28 is connected to the rear end flange of the discharge pipe 27, and the drain pipe 28 leads to the circulating water sedimentation tank;

[0044] The top of the mixing drum 23 is fixed with a drum cover by annular bolts, a motor 29 is bolted to the center of the drum cover, a bearing groove is provided in the center of the drum cover, a sealed bearing is inserted into the bearing groove with interference fit, a rotor shaft of the motor 29 passes through the inner ring of the sealed bearing with interference fit, and passes into the mixing drum 23 and is flange-connected with a rotary rod 30, and stirring blades 31 are bolted to the rotary rod 30 evenly at the upper and lower positions.

[0045] When the motor 29 is running, it can drive the rotating rod 30 to rotate, thereby driving the stirring blade 31 to rotate, so as to stir the mineral precipitation reagent and water in the stirring drum 23, accelerate the mixing of the two, and then more effectively adsorb and precipitate the minerals in the water when discharged into the sedimentation tank.

[0046] See also Figure 1 and Figure 2A top pipe 32 is integrally provided on the right side of the top of the mixing drum 23, and the top pipe 32 is connected to the mixing drum 23. The top flange of the top pipe 32 is connected to an inlet pipe 33, and the right end flange of the inlet pipe 33 is connected to an electromagnetic valve 34. The discharge end of the electromagnetic valve 34 is connected to the discharge pipe of the high-level storage tank of the mineral precipitation reagent through a feed pipe 35.

[0047] Among them, the electric control input end of the solenoid valve three 34 is connected to the electric control terminal of the external PLC through a cable, and the external PLC sets the valve opening delay and valve closing delay of the solenoid valve three 34 according to the amount of circulating water treated by the sedimentation tank.

[0048] The working principle of this embodiment is as follows: the sewage pump 2 draws the water to be treated from the upper-level circulating water pipeline, and then branches into different pipelines to be discharged to each filtering mechanism, and the filtering mechanism in each filtering mechanism effectively removes the micro-particles in the water, and discharges it to the dosing stirring mechanism, after being mixed with the mineral precipitation reagent and stirred on both sides, it is finally discharged to the sedimentation tank;

[0049] When the filter mechanism needs to be replaced, it is only necessary to close the solenoid valve 1 7 and the solenoid valve 2 25 on both sides of the filter mechanism that needs to be replaced, and keep the solenoid valve 1 7 and the solenoid valve 2 25 on both sides of the other filter mechanisms open, so that during the process of replacing the filter mechanism, the other filter mechanisms can continue to remove micro-particles.

[0050] During the process of replacing the filter mechanism, the top rod of the control hydraulic cylinder 21 is retracted, driving the filter mechanism to escape from the filter cartridge 9, unscrewing the outer support cylinder 16 out of the support ring 13, pouring out the cladding 18 and the filter column 19 in the outer support cylinder 16, loading the new cladding 18 and the filter column 19 into the outer support cylinder 16, and tightening the outer support cylinder 16 onto the support ring 13 again, and controlling the top rod of the control hydraulic cylinder 21 to extend, driving the filter mechanism to reinsert the filter cartridge 9, so that the replacement operation is also relatively convenient.
