Description

Technical Field

[0001] This application relates to the technical field of industrial production equipment, and in particular, to an integrated manifold. Background Art

[0002] Integrated manifolds are mainly used for the collection operations of oil, natural gas, combustible ice, etc. In the existing development technologies, the collection methods of combustible ice mainly include the pressure reduction method, the thermal stimulation method, and the chemical potential difference driving method. The pressure reduction mining faces the problems of sensible heat in the reservoir, insufficient environmental heat transfer leading to the reverse reaction of hydrate regeneration and the generation of ice, ultimately resulting in discontinuous gas production and reduced efficiency; the common methods of the thermal stimulation method mainly include injecting hot water or steam, microwave heating, and electric heating, etc. However, a large number of studies on injecting heat to drive the decomposition of natural gas hydrates show that there are temperature transfer differences in the heat injection process, and most of the heat is consumed in heating the entire reservoir temperature, and the mining thermal efficiency is not high; while the chemical potential difference driving method has problems such as the injection agent damaging the environment and poor replacement mining efficiency.

[0003] Based on the deficiencies of the above-mentioned mining methods, currently, there is an exploration to use a combination of mechanical crushing, pumping, and in-pipe gasification for mining. This method has advantages in both mining speed and mining efficiency. However, its products consist of gas, liquid, hydrate, hard debris, etc. During the subsequent transportation process, trace bubbles in the liquid will cause cavitation, and at the same time, the hard debris will also cause wear to the valves and pipes in the integrated manifold, resulting in a decrease in the service life of the valves and pipes, etc. Especially when performing underwater operations, this problem is particularly prominent. Summary of the Invention

[0004] This application provides an integrated manifold, which removes trace bubbles and hard debris in the product by actively filtering and actively degassing the collected product, so as to achieve the effect of protecting valves and pipes, and can effectively extend the service life of valves and pipes, etc.

Detailed Embodiment

[0036] The following further elaborates on the technical solutions in this application with reference to the accompanying drawings.

[0037] This application discloses an integrated manifold. Referring to Figure 1 , in some examples, the integrated manifold disclosed in this application includes a skid 1, a manifold body 2, a processing chamber 3, an input port 4, a pressure relief valve 5, an ultrasonic generator 6, an output port 7, and an interceptor 8. The manifold body 2 is fixedly installed on the skid 1.

[0038] The skid 1 here refers to a modular designed common base used to integrate fixed equipment and its attached components to form a functionally unit that can be moved as a whole. Its structure is usually welded with section steel or hollow pipes. The bottom surface is flat and the anchor bolts are evenly arranged for connection and fixation.

[0039] The manifold body 2 is a housing, and some equipment and its attachments are installed inside the manifold body 2. The manifold body 2 can provide a closed working environment to isolate external influences, such as moisture in the air, corrosive components, and seawater.

[0040] The number of treatment chambers 3 is two. Both of these treatment chambers 3 are arranged inside the manifold body 2. The input ports 4 are arranged on the manifold body 2 and are respectively connected to the two treatment chambers 3, and their function is to send the collected products into the treatment chambers 3 for processing.

[0041] The pressure relief valve 5 is arranged on the manifold body 2 and is connected to the treatment chamber 3, mainly playing a safety role. The pressure relief valve 5 has a limit pressure value. When the pressure in the treatment chamber 3 is greater than this limit pressure value, the pressure relief valve 5 automatically opens, which can limit the maximum pressure in the treatment chamber 3.

[0042] As Figure 1 shown, each of the two treatment chambers 3 is equipped with a pressure relief valve 5. Of course, when the two treatment chambers 3 are in a connected state, it is also possible to configure one pressure relief valve 5.

[0043] Figure 1 On the manifold body 2 in Figure 1 two sets of treatment chambers 3 and their attachments are arranged, that is to say, the manifold body 2 in

[0044] Please refer to Figure 2 , the ultrasonic generator 6 is also arranged on the manifold body 2. Two working ends of the ultrasonic generator 6 respectively extend into the two treatment chambers 3, and its function is to remove the bubbles in the collected products. Two output ports 7 are arranged on the manifold body 2 and are respectively connected to the two treatment chambers 3. The two output ports 7 are alternately in an open state, coordinating with the alternating working state of the treatment chambers 3, so that the collected products can be continuously processed.

[0045] In addition, the two treatment chambers 3 are also in a connected state, and an interceptor 8 is arranged at the connection of the two treatment chambers 3. The function of the interceptor 8 is to further remove the solid impurities in the collected products.

[0046] Combined with an actual processing process, the collected product first enters one of the processing chambers 3 through the input port 4, and the ultrasonic generator 6 corresponding to the processing chamber 3 is started synchronously to emit ultrasonic waves to the collected product in the processing chamber 3.

[0047] When ultrasonic waves act on a liquid, the liquid is alternately compressed and expanded in high-pressure and low-pressure cycles. In the low-pressure stage, tiny vacuum bubbles (i.e., cavitation bubbles) are generated inside the liquid, and the gas dissolved in the liquid gradually diffuses into these bubbles, causing the bubble volume to increase. With the continuous action of ultrasonic waves, these bubbles continuously coalesce and grow in multiple pressure cycles, and finally rise rapidly to the liquid surface and burst due to buoyancy, thus realizing gas separation.

[0048] Combined with the content recorded in the background art, it can be seen that the collected product entering the processing chamber 3 includes water, gas, combustible ice, and impurities. The impurities are mainly generated during the mechanical crushing process. Since the entire transportation process is in a low-temperature state, the collected product is mainly water, combustible ice, impurities, and a small amount of gas.

[0049] The effect of ultrasonic waves acting on the liquid is very obvious. Therefore, a large amount of liquid is required to be present in the processing chamber 3. The collected product is first fed into the liquid in the processing chamber 3. At this time, ultrasonic waves intervene first to defoam the liquid in the processing chamber 3. During this process, the combustible ice will decompose to produce gas and liquid water, and the impurities will precipitate at the bottom of the processing chamber 3, and the gas will accumulate at the bottom of the processing chamber 3.

[0050] The gas in the processing chamber 3 will be discharged through the output port 7 and sent to the subsequent process for treatment. After the liquid in the processing chamber 3 accumulates to a certain amount, it is discharged through the drainage pipe, and the impurities at the bottom of the processing chamber 3 are discharged through the sewage valve at the bottom of the processing chamber 3.

[0051] In some possible implementation manners, the sewage valve at the bottom of the processing chamber 3 is opened at a fixed frequency.

[0052] In some possible implementation manners, an electric tracing heater is provided inside the manifold body 2. The electric tracing heater is used to heat the processing chamber 3 to prevent icing inside the processing chamber 3.

[0053] In some examples, a plurality of intercepting filters 31 are provided in the processing chamber 3. In the direction away from the connection between the input port 4 and the processing chamber 3, the plurality of intercepting filters 31 are arranged at intervals. The main function of the intercepting filter 31 is to intercept impurities to prevent impurities from entering the subsequent valves and pipelines and causing damage to the valves and pipelines.

[0054] In some examples, the middle part of the interception filter screen 31 is away from the connection between the input port 4 and the processing chamber 3, and the edge part of the interception filter screen 31 is close to the connection between the input port 4 and the processing chamber 3. That is, the shape of the interception filter screen 31 is conical. This shape can not only increase the interception area of the interception filter screen 31, but also prevent impurities from accumulating on the interception filter screen 31.

[0055] In some possible implementation manners, there is at least one interception filter screen 31 between the output port 7 and the liquid level in the processing chamber 3.

[0056] In some possible implementation manners, there is a sewage discharge channel 32 between the edge of the interception filter screen 31 and the inner wall of the processing chamber 3, as Figure 3 shown.

[0057] In some examples, please refer to Figure 4 and Figure 5 , the interceptor 8 includes an annular housing 81 and an interception plate group 82. The annular housing 81 is fixedly installed at the connection of two processing chambers 3. The number of the interception plate groups 82 is two, and these two interception plate groups 82 are symmetrically arranged inside the annular housing 81.

[0058] The interception plate group 82 includes interception plates arranged in sequence. There are gaps between adjacent interception plates. At the same time, in the direction close to the middle area of the two interception plate groups 82, the gaps between adjacent interception plates tend to decrease.

[0059] The interception plates have two functions. The first function is to intercept the impurities in the gas that are not intercepted by the interception filter screen 31. The second function is to enable a part of the moisture in the gas to condense on the interception plates. The condensed moisture can wash the impurities on the interception plates to prevent the interception plate group 82 from being blocked.

[0060] In some possible implementation manners, the direction of the gaps between adjacent interception plates is parallel to the direction of gravity.

[0061] In some examples, please refer to Figure 2 , Figure 6 and Figure 7 , each processing chamber 3 is provided with at least two groups of liquid level sensors 9. The detection heights of each group of liquid level sensors 9 are different. The function of the liquid level sensors 9 is to ensure the liquid level height in the processing chamber 3, so that the collected products fed into the processing chamber 3 will not directly contact the cavity in the processing chamber 3, because the ultrasonic generator 6 also needs to use the liquid to defoam the collected products.

[0062] The liquid level sensor 9 includes a laser signal transmitter 91 and a laser signal receiver 92. The axis of the working end of the laser signal transmitter 91 is not perpendicular to the detection surface of the laser signal receiver 92. The specific working principle is:

[0063] The signal emitted by the laser signal transmitter 91 is detected by the laser signal receiver 92 after being refracted by the liquid surface. The detection method of the laser signal receiver 92 is position detection. In the actual detection process, the position detection is a dynamic value. However, when the liquid surface in the processing chamber 3 is below the laser signal transmitter 91, the detection value of the laser signal receiver 92 is a stable value, and this stable value is close to a set value.

[0064] The reason for using two sets of liquid level sensors 9 is that when the feedback of the first set of liquid level sensors 9 reaches a stable value, the liquid replenishment starts to be prepared. When the feedback of the second set of liquid level sensors 9 reaches a stable value, the liquid replenishment starts, and it stops when the feedback of the first set of liquid level sensors 9 is a dynamic value.

[0065] This method reserves a startup time for the liquid replenishment, and at the same time sets the liquid replenishment start time, reducing the liquid replenishment frequency.

[0066] When the detection value of the laser signal receiver 92 is a stable value, it indicates that the liquid level in the processing chamber 3 is too low at this time, and liquid replenishment is required.

[0067] Taking Figure 2 the content shown as an example, the gas in the left processing chamber 3 passes through the interceptor 8 and flows out from the output port on the right. On the one hand, it can reduce the moisture content in the gas, and on the other hand, it can also dredge the interception plate group 82 on the right. The gas in the right processing chamber 3 passes through the interceptor 8 and flows out from the output port on the left, with the same effect.

[0068] The input end of the drainage pipe is located below the two sets of liquid level sensors 9 and above at least one interception filter screen 31.

[0069] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
