Description

Technical Field

[0001] The utility model belongs to the field of sewage pipeline systems, and specifically relates to a sewage pipeline system for industrial enterprises. Background Art

[0002] With the acceleration of the industrialization process, the wastewater discharge problem of industrial enterprises has become an important concern in the field of environmental protection. Especially in the coking industry, a large amount of industrial wastewater containing organic matter, heavy metals and other harmful substances is generated during the production process. If these wastewaters are directly discharged without proper treatment, they will cause serious pollution to the environment and affect the water body ecosystem. Therefore, environmental protection departments at all levels have strengthened the supervision of industrial enterprise wastewater discharge, requiring enterprises to conduct effective treatment before discharge and ensure that the discharge meets national environmental protection standards.

[0003] The existing sewage systems of industrial enterprises generally have problems such as complex pipeline layouts, inaccurate flow control, and large discharge fluctuations. These problems increase the difficulty of sewage treatment and easily lead to unstable discharges, posing potential environmental protection and safety hazards.

[0004] In addition, at present, before leaving the factory, the sewage pipes of industrial enterprises mostly use a Parshall flume to measure the sewage flow, and at the same time sample and detect the pollutant concentration, and then discharge it into the urban underground sewage gravity flow pipe network and then enter the sewage treatment plant. However, it is not easy to detect leaks in the current underground sewage gravity flow pipe network, which is likely to cause groundwater pollution. At the same time, after the underground sewage gravity flow pipe network is blocked, the sewage is likely to overflow to the ground, causing problems with the road surface or the surface environment, and it is not easy to clean and dredge the blockage.

[0005] At present, there are low-overhead sewage pressure flow pipes above the ground to carry out the sewage transportation task, which can solve the problems existing in the underground sewage gravity flow pipe network, but the cost of erecting the overhead pipe network is relatively high. And for the biochemical treatment systems configured with multiple coking systems, if they are changed to enter the overhead pipe network, unified metering and unified sampling are required to solve the corresponding problems.

[0006] To sum up, the existing sewage pipeline systems of industrial enterprises have many problems in aspects such as pipeline layout, flow control, sewage transportation methods, and unified metering and sampling, and a new type of sewage pipeline system is needed to solve these problems. Content of the Utility Model

[0007] The utility model provides a sewage pipeline system for industrial enterprises, which is suitable for connecting the treated sewage inside the enterprise to the municipal pipe network to achieve centralized treatment of wastewater, improve environmental protection efficiency and safety, and facilitate maintenance and sampling.

[0008] The technical solutions adopted by the utility model are as follows:

[0009] A sewage pipeline system for industrial enterprises, comprising a wastewater pipeline system, a confluence pipeline system and a sampling and detection system. The wastewater pipeline system is connected to the reflux pipeline system, and the sampling and detection system is connected to the confluence pipeline system.

[0010] The wastewater pipeline system includes wastewater pipelines, check valve 1 and valve 1. There are multiple wastewater pipelines. Check valve 1 and valve 1 are sequentially arranged on each wastewater pipeline.

[0011] The confluence pipeline system includes a confluence pipeline, a municipal sewage pipe network and a municipal sewage treatment plant. Multiple wastewater pipelines are connected to the confluence pipeline. The confluence pipeline is connected to the municipal sewage pipe network. The municipal sewage pipe network is connected to the municipal sewage treatment plant. Valve 2, a flowmeter, check valve 2 and valve 3 are sequentially arranged on the confluence pipeline. A bypass pipe 2 is connected to the confluence pipeline. Both ends of the bypass pipe 2 are located on both sides outside valve 2 and valve 3. A bypass valve 2 is arranged on the bypass pipe 2.

[0012] Furthermore, the wastewater pipeline system further includes a bypass pipe 1 and a bypass valve 1. The bypass pipe 1 is connected to multiple wastewater pipelines. The bypass valve 1 is arranged on the bypass pipe 1.

[0013] Furthermore, the wastewater pipeline system further includes a wastewater tank. A wastewater pump is arranged on each wastewater pipeline. A wastewater reflux pipe is connected to each wastewater pipeline. Both the wastewater reflux pipe and the wastewater pump are connected to the wastewater tank. The wastewater reflux pipe and the wastewater pump are located on one side of the bypass pipe 1 deviating from check valve 1. A valve 5 is arranged on the wastewater reflux pipe.

[0014] Furthermore, the sampling and detection system includes a sampling pipe. Both ends of the sampling pipe are connected to the confluence pipeline. One end of the sampling pipe is located after the connection between the wastewater pipeline and the confluence pipeline. The other end of the sampling pipe is located between the flowmeter and valve 2. A detection device and a sampling return pump are arranged on the sampling pipe. Valves 4 are arranged at both ends of the sampling pipe.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. By arranging check valve 1 and valve 1 on the wastewater pipeline, the utility model effectively prevents the backflow of sewage during the operation of the system, ensures the consistency of the wastewater discharge direction and the stability of the discharge process. This greatly reduces the risk of secondary pollution caused by sewage backflow and protects the safety of production equipment and other pipeline areas.

[0017] 2. The high-precision flowmeter installed on the confluence pipeline of the present utility model can monitor the sewage discharge volume in real time to ensure that the discharge meets the environmental protection standards. Compared with the original Parshall flume measurement method, the flowmeter has higher accuracy and reliability, providing strong support for the supervision of environmental protection departments. The valve two and valve three before and after the flowmeter and the bypass valve two on the bypass pipeline can ensure that the wastewater discharge does not stop when the flowmeter needs to be repaired, avoiding the problem of discharge interruption caused by maintenance.

[0018] 3. The on-line sampling and detection device adopted by the present utility model completely replaces the traditional Parshall flume sampling and detection method. It can sample and detect wastewater in real time, improving the detection efficiency. After sampling, the remaining water is pumped back to the main pipeline through the sampling return pump, avoiding the environmental pollution problem caused by unorganized discharge and reducing the risk of non-compliance of enterprise emissions.

[0019] 4. By designing the wastewater pipeline system, confluence pipeline system and sampling and detection system, the present utility model realizes the unified measurement and sampling of the wastewater generated by the biochemical treatment systems configured in multiple coking systems. This design solves the problem of how to send the wastewater from multiple systems to the same point on the same municipal overhead sewage pipeline. Brief Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings.

[0025] As shown Figure 1 in the figure, this embodiment provides a sewage pipeline system for industrial enterprises, including a wastewater pipeline system, a confluence pipeline system, and a sampling and detection system. The wastewater pipeline system is connected to the confluence pipeline system, and the sampling and detection system is connected to the confluence pipeline system. Among them, the wastewater pipeline system is mainly responsible for collecting and transporting the wastewater generated by industrial enterprises. The confluence pipeline system is responsible for aggregating the wastewater from the wastewater pipeline system and transporting it to the municipal sewage pipe network 14 or the municipal sewage treatment plant 15. The sampling and detection system is used to sample and detect the wastewater to ensure that the wastewater quality meets the relevant environmental protection standards.

[0026] Specifically, the wastewater pipeline system includes wastewater pipelines, check valve 1 5, and valve 1 6. There are multiple wastewater pipelines, which correspond to the biochemical treatment systems configured in multiple coking systems (such as the second phase, the third phase, etc.) in the industrial enterprise. In this embodiment, taking the example that a same enterprise has the need to discharge the treated wastewater in the second phase, there are two wastewater pipelines, namely wastewater pipeline 1 1 and wastewater pipeline 2 2. A check valve 1 5 and a valve 1 6 are sequentially arranged on each wastewater pipeline. The check valve 1 5 prevents the sewage from flowing back during the operation of the system, ensuring the consistency of the discharge direction and the stability of the discharge process. And when the system fails or is under maintenance, the check valve can effectively prevent the pollutants from flowing back to the production equipment or other pipeline areas, reducing the risk of secondary pollution. The valve 1 6 is used to control the opening and closing of the wastewater pipeline, realizing the discharge and truncation of the wastewater. When the system needs maintenance or repair, the relevant pipeline can be isolated from the system by closing the valve 1 6 to ensure the safety of the maintenance work.

[0027] To avoid affecting the treatment of normal wastewater in the first and second phases due to the stop of external discharge, the wastewater pipeline system further includes a bypass pipe 1 3 and a bypass valve 1 4. The bypass pipe 1 3 is connected to multiple wastewater pipelines, and a bypass valve 1 4 is arranged on the bypass pipe 1 3, which can be switched for use when needed. A wastewater pump 21 is arranged on each wastewater pipeline, and a wastewater return pipe 20 is connected to each wastewater pipeline. Both the wastewater return pipe 20 and the wastewater pump 21 are connected to the wastewater tank 22. The wastewater return pipe 20 and the wastewater pump 21 are located on the side of the bypass pipe 1 3 deviating from the check valve 1 5, and a valve 5 23 is arranged on the wastewater return pipe 20. The bypass pipe 1 3 can be connected to sewage pipeline 1 and sewage pipeline 2, enabling them to communicate with each other when necessary. When the pressure of the municipal sewage pipe network 14 is relatively high and the external discharge needs to be suspended, the sewage in the first phase or the second phase can be sent to the wastewater tank 22 in the second phase or the first phase for mutual storage. Among them, the wastewater pump 21 is used to provide power to pump the wastewater out of the wastewater pipeline and transport it to the confluence pipeline 7 or the wastewater tank 22, and can cooperate with the valve 5 23 to flexibly control the flow direction and flow rate of the wastewater, ensuring the stable operation of the system and realizing the mutual reserve of the two wastewater tanks 22.

[0028] Specifically, asFigure 1 As shown in the figure, the confluence pipeline system includes a confluence pipeline 7, a municipal sewage pipe network 14, and a municipal sewage treatment plant 15. Multiple wastewater pipes are connected to the confluence pipeline 7. In this embodiment, specifically, wastewater pipe 1 and wastewater pipe 2 are connected to the confluence pipeline 7. The confluence pipeline 7 is connected to the municipal sewage pipe network 14, and the municipal sewage pipe network 14 is connected to the municipal sewage treatment plant 15. A valve 2 8, a flowmeter 10, a check valve 2 11, and a valve 3 9 are sequentially arranged on the confluence pipeline. Among them, the flowmeter 10 is used to monitor the sewage flow in the system in real time to ensure that the wastewater discharge meets the relevant environmental protection requirements. The check valve 2 11 can prevent the pressurized sewage in the municipal sewage pipe network 14 from flowing back after stopping the supply of wastewater treatment to the outside, and through this confluence pipeline 7 and its flowmeter 10, it may cause the flowmeter 10 to display an incorrect flow rate.

[0029] To ensure that the enterprise can maintain normal sewage discharge during system equipment maintenance or failures, a bypass pipe 2 12 is connected to the confluence pipeline 7. Both ends of the bypass pipe 2 12 are located on both sides outside the valve 2 8 and the valve 3 9. A bypass valve 2 13 is arranged on the bypass pipe 2 12. When the flowmeter 10 on the confluence pipeline 7 needs to be repaired, the valve 2 8 and the valve 3 9 before and after the flowmeter 10 can be closed, and the wastewater can be guided to bypass the main confluence pipeline 7 directly through the bypass pipe 2 12 for discharge, avoiding the discharge interruption caused by the maintenance of the flowmeter 10 being out of service.

[0030] The sampling and detection system includes a sampling pipe 16. Both ends of the sampling pipe 16 are connected to the confluence pipeline 7. One end of the sampling pipe 16 is located after the connection between the wastewater pipe and the confluence pipeline 7, and the other end of the sampling pipe 16 is located between the flowmeter 10 and the valve 2 8. A detection device 18 and a sampling return pump 19 are arranged on the sampling pipe 16. Valves 4 17 are arranged at both ends of the sampling pipe 16. Through the sampling and detection system, the remaining water after sampling is sent back to the main confluence pipeline 7 by the sampling return pump 19, and there will be no unorganized external discharge to pollute the environment. At the same time, it no longer passes through the underground sewage pipe network, completely abandons the underground wastewater pipe network, and also completely eliminates the Parshall flume as a wastewater measurement device.

[0031] The working principle of the present utility model is as follows:

[0032] When sewage discharge is required, the valve 1 6 is opened, and the wastewater is transported to the confluence pipeline 7 through the wastewater pipe 1 and the wastewater pipe 2. The check valve 1 5 prevents the sewage from flowing back. In the confluence pipeline system, the wastewater sequentially passes through the valve 2 8, the flowmeter 10, the check valve 2 11, and the valve 3 9, and finally is discharged into the municipal sewage pipe network 14 or the municipal sewage treatment plant 15. At the same time, the flowmeter 10 monitors the sewage discharge volume in real time, and the check valve 2 11 prevents the pressurized sewage in the municipal sewage pipe network 14 from flowing back after stopping the supply of wastewater treatment to the outside.

[0033] If the pressure of the municipal sewage pipe network 14 is relatively high and external drainage needs to be postponed, open the first bypass valve 4, and the sewage will communicate with each other in the first wastewater pipe 1 and the second wastewater pipe 2 through the first bypass pipe 3. If the flow rate in the first wastewater pipe 1 is large, open the wastewater pump 21 and the fifth valve 23 on the second flow pipe, and pump the wastewater in the first wastewater pipe 1 into the corresponding wastewater tank 22 in the second wastewater pipe 2 to relieve the flow pressure.

[0034] If the flowmeter 10 needs to be repaired, close the second valve 8 and the third valve 9, and the sewage will bypass the main confluence pipe 7 through the second bypass pipe 12 and be directly discharged to avoid interruption of discharge.

[0035] If sampling and detection are required, open the fourth valves 17 at both ends of the sampling pipe 16, the sewage will flow through the detection device 18 for sampling and detection, and then be sent back to the confluence pipe 7 through the sampling return pump 19.

[0036] The improved system can better meet the strict requirements of national and local environmental protection regulations, and effectively reduce the possibility of pollutant emissions. Through precise control and monitoring, it can ensure that the sewage treatment at each stage meets the specified standards, and reduce the risk of fines or rectification for enterprises due to non-compliant emissions.

[0037] The above has described in detail an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
