Description

Technical Field

[0001] The utility model relates to the technical field of underwater debris cleaning equipment, in particular to an air drainage pump tail gas recovery and utilization device. Background Art

[0002] During the annual inspection of the jacket of an offshore oil platform, as the platform is a fixed platform, it is necessary to conduct regular inspection and cleaning of the jacket in accordance with relevant specifications. The shells of cleaned marine organisms (oysters, shellfish, conchs, etc.) and silt sediments in the marine environment will bury the structural parts close to the seabed. Divers need to be sent underwater to clean the structural parts regularly.

[0003] The existing technology generally requires divers to carry fire hoses and use water guns underwater to clean the buried silt. Or use air lift pumps to clean the silt. The efficiency is low and the underwater environment is complex, making it difficult for the equipment to reach the designated location. In addition, the previous air lift equipment was large in size, making it difficult for divers to carry the equipment to the designated location. Air lift equipment generally has a filter device, and the pump head is easily clogged. Even if the silt is blown away, some marine organisms cannot be taken away from the vicinity and can only be picked up by divers. This operation method is not only extremely inefficient, but also causes certain damage to the body of divers staying underwater for a long time.

[0004] Therefore, how to provide an air drainage pump tail gas recovery and utilization device to solve the problem that the existing cleaning equipment cannot completely handle marine organisms is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0005] To this end, the utility model provides an air drainage pump tail gas recovery and utilization device to solve the problem in the prior art that the cleaning equipment cannot completely carry away the marine organisms, resulting in unclean cleaning and easy clogging.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses an air drainage pump tail gas recovery and utilization device, comprising:

[0008] A pneumatic lifting pipe, the bottom of which is attached to the surface of the underwater component, and the top of the pneumatic lifting pipe is connected to a sewage pipe;

[0009] An exhaust pipe is inserted into the side of the pneumatic lifting pipe, the exhaust end of the exhaust pipe is arranged in the pneumatic lifting pipe, and the air inlet end of the exhaust pipe is connected to the exhaust end of the pneumatic submersible pump;

[0010] An air intake and discharge pipe is inserted into the side of the pneumatic lifting pipe, the exhaust end of the air intake and discharge pipe is arranged in the pneumatic lifting pipe, and the air intake end of the air intake and discharge pipe is inserted into the air intake pipe body of the pneumatic submersible pump;

[0011] The air intake and exhaust pipe is arranged above the exhaust pipe, the exhaust pipe outlet surface is at 45° with the upper surface of the pneumatic lift pipe, and the air intake and exhaust pipe outlet surface is parallel to the upper surface of the pneumatic lift pipe.

[0012] In a possible implementation, the pneumatic lift pipe includes:

[0013] A pipe body, the bottom of which is placed on the surface of the underwater component;

[0014] Pipe connection holes are arranged in pairs and are opened on the side wall of the pipe body, and the exhaust pipe and the intake pipe are inserted into the pipe connection holes;

[0015] The first flange is installed at the upper end of the pipe body, and the pipe body is connected to the sewage pipe through the flange.

[0016] In a possible implementation, the exhaust gas exhaust pipe includes:

[0017] A first exhaust pipe body, one end of which is inserted into the pneumatic lifting pipe;

[0018] The second flange is mounted on the other end of the first exhaust pipe body.

[0019] In a possible implementation, the air intake and exhaust pipe includes:

[0020] A second exhaust pipe body, one end of which is inserted into the pneumatic lifting pipe;

[0021] A circulation valve, one end of which is sleeved on the other end of the second exhaust valve;

[0022] One end of the air inlet pipe body is inserted into the other end of the circulation valve, and the other end of the air inlet pipe body is inserted into the air inlet pipe body of the pneumatic submersible pump.

[0023] In a possible implementation, the tube body is a large-diameter tube body, and the tube body is a stainless steel thin-wall tube.

[0024] In a possible implementation, the gas outlet surface of the first exhaust pipe body and the bottom surface of the second flange plate form an angle of 45 degrees.

[0025] In a possible implementation, the outlet surface of the second exhaust pipe body is at 90 degrees to the inlet surface of the inlet pipe body, and the flow valve is a ball valve.

[0026] The utility model effectively utilizes the gas in the pneumatic submersible pump to discharge the used gas of the pneumatic submersible pump into the pneumatic lifting pipe, so that a state similar to "negative pressure" is formed in the pipe. Driven by the gas, marine organisms and silt are guided to move upward along the pneumatic lifting pipe, and then discharged along the sewage pipe. At the same time, the air intake and discharge pipes use the gas just sucked in by the pneumatic submersible pump. The setting of two air outlet directions makes the internal flow of gas more uniform. This equipment not only solves the problem that the prior art has poor effect in treating marine organisms, but also effectively utilizes the gas used by the pneumatic submersible pump, and the discharge efficiency of marine organisms is also significantly improved.

[0034] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please refer to Figure 1-Figure 4 Now, an air drainage pump tail gas recovery and utilization device disclosed in the utility model is described. The utility model is composed of three parts, such as Figure 1 , comprising a pneumatic lifting pipe 1, an exhaust gas exhaust pipe 2 and an air intake exhaust pipe 3. The bottom of the pneumatic lifting pipe 1 is attached to the surface of the underwater component, the top of the pneumatic lifting pipe 1 is connected with a sewage pipe, the exhaust gas exhaust pipe 2 is inserted at the side of the pneumatic lifting pipe 1, the exhaust end of the exhaust gas exhaust pipe 2 is arranged in the pneumatic lifting pipe 1, the air intake end of the exhaust gas exhaust pipe 2 is connected to the exhaust end of the pneumatic submersible pump, the air intake exhaust pipe 3 is inserted at the side of the pneumatic lifting pipe 1, the exhaust end of the air intake exhaust pipe 3 is arranged in the pneumatic lifting pipe 1, the air intake end of the air intake exhaust pipe 3 is inserted in the air intake pipe body of the pneumatic submersible pump, the air intake exhaust pipe 3 is arranged above the exhaust gas exhaust pipe 2, the exhaust surface of the exhaust pipe 2 is 45° with the upper surface of the pneumatic lifting pipe 1, and the exhaust surface of the air intake exhaust pipe 3 is parallel to the upper surface of the pneumatic lifting pipe 1.

[0036] When the utility model is in use, the tail gas exhaust pipe 2 and the air intake exhaust pipe 3 are connected to the air intake pipe and the air outlet pipe of the pneumatic submersible pump respectively. When the pneumatic submersible pump starts to operate, air will be sucked in. After the gas is used up, it will enter the tail gas exhaust pipe 2 along the air outlet pipe, and then be discharged into the pneumatic lifting pipe 1 through the tail gas exhaust pipe 2. At this time, the gas circulation mode is from bottom to top, so that a state similar to "negative pressure" is formed inside the pneumatic lifting pipe 1. In this state, the silt and marine organisms at the bottom of the pneumatic lifting pipe 1 can be driven to the sewage pipe above. The use of the air intake exhaust pipe 3 is when the exhaust gas pressure is not enough or when the internal circulation gas needs to be stable. As for the exhaust direction of the gas, the gas discharged from the tail gas exhaust pipe 2 flows to Figure 1 The right half shown in FIG. 1 , and the direction of the exhaust gas from the intake and exhaust pipe 3 is Figure 1 The left half is shown in the figure. This can ensure the stability of the internal gas circulation. The two gas streams can also speed up the flow rate and improve the impurity removal efficiency.

[0037] In a specific embodiment, Figure 2The pneumatic lifting pipe 1 includes a first flange 11, a pipe body 12 and a pipe connection hole 13. The bottom of the pipe body 12 is placed on the surface of the underwater component. The pipe connection holes 13 are arranged in pairs and are opened on the side wall of the pipe body 12. The exhaust gas exhaust pipe 2 and the intake exhaust pipe 3 are inserted into the pipe connection hole 13. The first flange 11 is installed on the upper end of the pipe body 12. The pipe body 12 is connected to the sewage pipe through a flange. The flange connection method not only makes the connection more stable, but also effectively prevents leakage inside and outside the pipe. The pipe body connection hole 13 is used to install two exhaust pipes. After the connection is completed, the connection position is welded to effectively prevent leakage inside and outside the pipe.

[0038] In a specific embodiment, Figure 3 The exhaust pipe 2 includes a first exhaust pipe body 21 and a second flange 22. One end of the first exhaust pipe body 21 is inserted into the pneumatic lifting pipe 1, and the second flange 22 is installed at the other end of the first exhaust pipe body 21. The second flange 22 has the same effect as the first flange 11, and can prevent water from entering the first exhaust pipe body 21.

[0039] In a specific embodiment, Figure 4 The air intake and exhaust pipe 3 includes a second exhaust pipe body 31, a circulation valve 32 and an air intake pipe body 33. One end of the second exhaust pipe body 31 is inserted in the pneumatic lifting pipe 1, one end of the circulation valve 32 is sleeved on the other end of the second exhaust valve 31, one end of the air intake pipe body 33 is inserted in the other end of the circulation valve 32, and the other end of the air intake pipe body 33 is inserted in the air intake pipe body of the pneumatic submersible pump. The flow is intercepted by the circulation valve 32, because the use of the air intake and exhaust pipe 3 is not always used like the exhaust pipe 2, but the circulation valve 32 is opened for ventilation when necessary. The connection position of the air intake pipe body 33 and the pneumatic submersible pump is still connected by welding, which not only improves the installation stability, but also prevents leakage.

[0040] In a specific embodiment, the tube body 12 is a large-diameter tube body, and the tube body 12 is a stainless steel thin-walled tube. The large-diameter tube body is to solve the problem of marine organisms blocking the shell. This large diameter is generally 10 inches in size, which can greatly reduce the clogging of marine organisms. The use of stainless steel thin-walled tubes is to reduce the weight of the tube body 12 to prevent difficulties in underwater transportation and to prevent seawater erosion, which shortens the service life of the equipment.

[0041] In a specific embodiment, the outlet surface of the first exhaust pipe body 21 is 45° to the bottom surface of the second flange 22. During the gas transportation process, the gas will be under pressure, and the angles of the inlet and outlet indicate that an elbow is set, and the elbow can effectively reduce pipeline stress and prevent pipeline deformation. At the same time, the elbow can also change the gas ejection angle.

[0042] In a specific embodiment, the outlet surface of the second exhaust pipe body 31 is 90° with the inlet surface of the inlet pipe body 33, and the flow valve 32 is a ball valve. Similarly, according to the principle of the previous embodiment, the inlet and outlet pipe 3 is also set as a curved pipe, which can achieve the same purpose. The ball valve is used because the valve seat of the ball valve is made of elastic material with good sealing performance. At the same time, the flow channel of the ball is also very straight, with a large flow rate, which can meet the needs of large flow delivery. At the same time, the ball valve can generate a large pressure between the ball and the valve seat in the closed state, and can withstand a large pressure difference. Therefore, the ball valve has the characteristics of high reliability and good safety performance.

[0043] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
