Description

TECHNICAL FIELD

[0001] The application relates to the technical field of membrane treatment equipment, and more particularly to a PH value anti-blocking module of a membrane treatment equipment. BACKGROUND

[0002] In order to reduce the negative influence of exhaust gas of a ship diesel engine on the atmospheric environment, a ship exhaust gas cleaning system is installed on an existing diesel engine ship.

[0003] The exhaust gas cleaning system comprises a washing tower and a filtering module. After being combusted, oil in the diesel engine of the ship is mixed with a large amount of acidic substances, such as sulfur dioxide. The exhaust gas containing the acidic substances rises from the bottom of the washing tower and fully contacts with a fluid alkaline agent sprayed at the top of the washing tower, is absorbed by the fluid alkaline agent, and forms waste water. The waste water flows into a waste water storage bin through a pipeline. The filtering module is a device for treating the waste water. After the waste water is sent into the filtering module from the waste water storage bin, the waste water is filtered by the filtering module and produces clean water and sludge. It needs to be supplemented that the fluid alkaline agent is mainly magnesium hydroxide solution or sodium hydroxide solution. In order to achieve sufficient absorption of the exhaust gas, an excessive amount of magnesium hydroxide solution or sodium hydroxide solution is often added. However, because magnesium hydroxide is difficult to dissolve in water, the magnesium hydroxide is difficult to filter through the filter hole due to the large particle size after flowing into the filtering module with the waste water, and is often accumulated on the surface of the membrane body, thereby blocking the membrane body in the filtering module, affecting the normal work of the filtering module, and shortening the service life of the filter membrane.

[0004] Therefore, there is a demand for a PH value anti-blocking module of a membrane treatment equipment, which can detect the PH value of waste water and help to reduce the risk of membrane body blockage. SUMMARY

[0027] A PH value anti-blocking module of a membrane treatment device according to the present application, with reference to Figures 1 to 4 A PH value anti-blocking module of a membrane treatment device according to the present application, with reference to

[0028] Further, the PH value anti-blocking module of the membrane treatment device comprises a feeding pipe 10 and a PH meter 20. One end of the feeding pipe 10 is in communication with the wastewater storage bin, and the other end of the feeding pipe 10 is in communication with the sewage filtration module. The PH meter 20 is arranged on the feeding pipe 10.

[0029] It should be noted that by arranging the feeding pipe 10 and the PH meter 20 between the sewage filtration module and the wastewater storage bin, the PH value of the wastewater flowing into the feeding pipe 10 can be detected by the PH meter 20. When the PH value of the wastewater flowing into the feeding pipe 10 exceeds a predetermined value, the wastewater is stopped from further flowing into the sewage filtration module, so as to avoid the membrane body in the sewage filtration module being blocked due to the magnesium hydroxide contained in the wastewater. It should be further noted that the magnesium hydroxide is alkaline, and the wastewater as a whole is alkaline. In the embodiment of the present application, the maximum rated value of the PH meter 20 is set to be within the range of 8-8.5. When the PH value of the wastewater flowing into the feeding pipe 10 exceeds the maximum rated value, the channel between the feeding pipe 10 and the sewage filtration module is cut off, and the wastewater cannot flow into the sewage filtration module any more. Compared with the prior art, the embodiment of the present application has the advantages of being capable of detecting the PH value of the wastewater and helping to reduce the risk of membrane body blockage.

[0030] Further, in order to prevent the wastewater from flowing into the sewage filtration module when the PH value of the wastewater exceeds the maximum rated value, as shown in Figure 2 Further, the PH value anti-blocking module of the membrane treatment device further comprises a sewage backflow pipe 30. One end of the sewage backflow pipe 30 is in communication with the end of the feeding pipe 10 close to the sewage filtration module, and the other end of the sewage backflow pipe 30 is in communication with the wastewater storage bin. The PH value anti-blocking module of the membrane treatment device further comprises a first valve 101 and a second valve 301. The first valve 101 is arranged on the feeding pipe 10 and located between the sewage filtration module and the sewage backflow pipe 30. The second valve 301 is arranged on the sewage backflow pipe 30.

[0031] It should be noted that under normal circumstances, the first valve 101 is always open, and the second valve 301 is always closed. At this time, the sewage flows into the sewage filtration module along the feeding pipe 10. When the PH value of the wastewater exceeds the maximum rated value, the first valve 101 is closed, and the second valve 301 is opened. Then, the sewage flows into the sewage backflow pipe 30 along the feeding pipe 10 and flows into the wastewater storage cavity.

[0032] Further, in order to avoid the wastewater flowing at too high a speed, causing the sludge particles flowing at too high a speed to have a large impact on the glass probe of the PH meter 20, as shown inFigure 2 As shown in the figure, the PH value anti-blocking module of the membrane treatment equipment further comprises an extension pipe 102, both ends of the extension pipe 102 are communicated with one end of the feeding pipe 10 close to the wastewater storage bin, the PH meter 20 is installed on the extension pipe 102, two flow valves 1021 are installed on the extension pipe 102, and the two flow valves 1021 are located at both ends of the PH meter 20.

[0033] It should be noted that the flow rate of the wastewater flowing into the extension pipe 102 is adjusted by the flow valves 1021, the damage probability of the glass probe of the PH meter 20 is reduced, and the glass probe of the PH meter 20 can more accurately measure the PH value of the wastewater; in addition, when the PH meter 20 fails, the two flow valves 1021 can be closed to disassemble, replace and repair the PH meter 20.

[0034] In addition, as shown in the figure, Figure 2 A flow meter 1022 is installed on the feeding pipe 10, and the flow rate of the fluid in the feeding pipe 10 can be directly and intuitively known through the flow meter 1022.

[0035] Further, in the embodiment of the present application, the sewage filtration module comprises a pre-filter 40, a primary sewage filtration pipe group 50 and a circulating filtration module 60, one end of the feeding pipe 10 away from the wastewater storage bin is communicated with the water inlet of the pre-filter 40, one end of the primary sewage filtration pipe group 50 is communicated with the water outlet of the pre-filter 40, and the other end of the primary sewage filtration pipe group 50 is communicated with the circulating filtration module 60.

[0036] It should be noted that the wastewater flows into the pre-filter 40 for preliminary filtration of large-particle pollutants in the wastewater, after passing through the pre-filter 40, the wastewater after preliminary filtration flows into the primary sewage filtration pipe group 50 and then flows into the circulating filtration module 60 along the primary sewage filtration pipe group 50, and clean water and sludge are generated through the circulating filtration module 60.

[0037] Further, in the embodiment of the present application, as shown in the figure, Figure 3 The circulating filtration module 60 comprises a circulating pump 601, a circulating pipeline 602 and two filter cartridges 603, the circulating pump 601 is connected with the two filter cartridges 603 through the circulating pipeline 602 between the water inlet and the water outlet of the circulating pump 601, the primary sewage filtration pipe group 50 comprises a first primary filtration pipe 501 and a second primary filtration pipe 502, and the water outlet ends of the first primary filtration pipe 501 and the second primary filtration pipe 502 are respectively communicated with the circulating pipeline 602 on both ends of one of the filter cartridges 603.

[0038] It should be noted that the filter cartridge 603 is provided with a filter membrane, and the primary filtered wastewater flows into the circulating pipeline 602 from the first primary filter pipe 501 and the second primary filter pipe 502, and the wastewater flowing into the circulating pipeline 602 is driven by the circulating pump 601 to flow in the circulating pipeline 602, and the wastewater flows through the filter membrane after flowing into the filter cartridge 603 and produces clean water.

[0039] It should be further noted that by providing the first primary filter pipe 501 and the second primary filter pipe 502, the distance of the sewage from the two filter cartridges 603 is similar after flowing into the circulating pipeline 602, which avoids the sewage continuously flowing from one side of the filter cartridge 603, resulting in that the filtering burden of the filter cartridge 603 close to the primary sewage filter pipe group 50 is greater than the filter cartridge 603 far away, and has the advantage that the water inflow is more uniform when the wastewater flows into the circulating pipeline 602, which helps to make the blockage degree of the filter membranes in the two filter cartridges 603 similar.

[0040] More specifically, to realize the connection of the first primary filter pipe 501 and the second primary filter pipe 502 with the circulating pipeline 602, as shown in Figure 3 The circulating pipeline 602 includes a straight pipe 6021, a U-shaped pipe 6022 and an L-shaped pipe 6023, two ends of the U-shaped pipe 6022 are respectively communicated with two filter cartridges 603, two ends of the straight pipe 6021 are respectively communicated with the inlet of the circulating pump 601 and one end of the filter cartridge 603 away from the U-shaped pipe 6022, two ends of the L-shaped pipe 6023 are respectively communicated with the outlet of the circulating pump 601 and the other filter cartridge 603 away from the U-shaped pipe 6022, the water outlet end of the first primary filter pipe 501 is communicated with the straight pipe 6021, the water inlet end of the second primary filter pipe 502 is communicated with the first primary filter pipe 501, and the water outlet end of the second primary filter pipe 502 is communicated with the U-shaped pipe 6022.

[0041] Further, to realize the discharge of the sludge in the circulating pipeline 602, as shown in Figure 1 , Figure 3 and Figure 4As shown, the membrane treatment device further comprises a sludge module 70, which comprises a sludge tank 701, a sludge inflow pipe 702, a sludge outflow pipe 703, a sludge pump 704 and a sludge backblowing pipe 705. Two ends of the sludge inflow pipe 702 are respectively connected with the circulation pipe 602 and the sludge tank 701. One end of the sludge outflow pipe 703 is connected with the sludge tank 701, and the other end of the sludge outflow pipe 703 is connected with an external sludge dewatering module (not shown in the figure). The sludge pump 704 is connected between the sludge outflow pipe 703 and the sludge tank 701. The sludge backblowing pipe 705 is connected with the sludge tank 701 and the sludge outflow pipe 703 at two ends respectively. In addition, a pressure gauge 7034 and a pressure transmitter 7035 are installed on the sludge outflow pipe 703.

[0042] More specifically, in the embodiment of the present application, as shown in Figure 4 As shown, the sludge outflow pipe 703 comprises a first sludge discharge pipe 7031, a second sludge discharge pipe 7032 and a third sludge discharge pipe 7033. One end of the first sludge discharge pipe 7031 is connected with the sludge tank 701, and the other end of the first sludge discharge pipe 7031 is connected with the sludge inlet of the sludge pump 704. One end of the second sludge discharge pipe 7032 is connected with the sludge outlet of the sludge pump 704, and the other end of the second sludge discharge pipe 7032 is connected with the third sludge discharge pipe 7033. One end of the third sludge discharge pipe 7033, which is away from the second sludge discharge pipe 7032, is connected with an external sludge dewatering module. One end of the sludge backblowing pipe 705 is connected with the sludge tank 701, and the other end of the sludge backblowing pipe 705 is connected with the connection position of the third sludge discharge pipe 7033 and the second sludge discharge pipe 7032. Valves are installed on the first sludge discharge pipe 7031, the second sludge discharge pipe 7032 and the sludge backblowing pipe 705.

[0043] It should be noted that the sludge in the circulation pipeline 602 flows into the sludge tank 701 along the sludge inflow pipe 702, the sludge tank 701 is used for storing sludge, when the valve on the sludge outflow pipe 703 is opened, the valve on the sludge backblowing pipe 705 is closed, and the sludge pump 704 works, the sludge flows from the sludge tank 701 into the first sludge discharge pipe 7031 and enters the sludge pump 704, and the sludge pump 704 sequentially sends the sludge into the second sludge discharge pipe 7032, the third sludge discharge pipe 7033, and finally to the external sludge dewatering module; in addition, the operator can directly observe the fluid pressure in the sludge outflow pipe 703 through the pressure gauge 7034; in addition, the pressure transmitter 7035 is electrically connected with the controller in the membrane treatment equipment, which provides a precondition for timely maintenance alarm for the special case that there is no sludge in the sludge outflow pipe 703 and the sludge pump 704 shows a working state; it should be noted that since the third sludge discharge pipe 7033 is relatively long in actual use, if the end of the third sludge discharge pipe 7033 away from the sludge pump 704 is blocked by sludge, the thrust provided by the sludge pump 704 may be insufficient to smoothly push the sludge to the external sludge dewatering module, therefore, in the embodiment of the present application, the sludge backblowing pipe 705 is provided, which provides a precondition for blowing external air into the third sludge discharge pipe 7033 and blowing the sludge blocked in the third sludge discharge pipe 7033 back to the sludge tank 701. Specifically, the valve on the sludge backblowing pipe 705 is normally closed, when the sludge pump 704 stops working and the sludge module 70 stops discharging sludge, the valve on the sludge backblowing pipe 705 is opened, the valve on the second sludge discharge pipe 7032 is closed, and external high-pressure air enters the sludge backblowing pipe 705 to clean the sludge in the pipe, so as to avoid the pipe being blocked due to the dryness of the residual sludge in the pipe.

[0044] In summary, the PH value anti-blocking module of the membrane treatment equipment based on the embodiment of the present application is illustrated, which provides the PH value anti-blocking module of the membrane treatment equipment with the advantages of detecting the PH value of wastewater and reducing the risk of membrane blockage.

[0045] It is worth mentioning that in the embodiment of the present application, the PH value anti-blocking module of the membrane treatment equipment has a simple structure and does not involve complex manufacturing processes and expensive materials, which has high economic efficiency. At the same time, for the manufacturer, the PH value anti-blocking module of the membrane treatment equipment provided by the present application is easy to produce and has low cost, which is more conducive to controlling the production cost and further promoting the product popularization and use.
