Description

Technical Field

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

[0002] The integrated manifold is mainly used for the collection of oil, natural gas and combustible ice. The existing development technology for collecting combustible ice mainly includes depressurization, thermal shock and chemical potential difference driving. Depressurization mining faces the problem of insufficient heat transfer in the reservoir and the environment, which leads to the reverse reaction of hydrate regeneration and ice production, and ultimately leads to discontinuous gas production and reduced efficiency. Common methods of thermal shock include injection of hot water or steam, microwave heating and electric heating. However, a large number of studies on heat injection-driven decomposition of natural gas hydrates have shown that there are temperature transfer differences in the heat injection process, and most of the heat is consumed in the heating of the entire reservoir temperature, so the thermal efficiency of mining is not high. The chemical potential difference driving method has problems such as injection of agents that damage the environment and poor displacement mining efficiency.

[0003] Based on the shortcomings of the above-mentioned mining methods, there is currently exploration of the use of a combination of mechanical crushing, pumping and in-pipeline gasification for mining. This method has advantages in both mining speed and mining efficiency, but its products are composed of gas, liquid, hydrates and hard debris. During the subsequent transportation process, trace bubbles in the liquid will cause cavitation. At the same time, hard debris will also cause wear on valves and pipelines in the integrated manifold, resulting in a decrease in the service life of valves and pipelines. This problem is particularly prominent during underwater operations. Summary of the invention

[0004] The present 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 protect valves and pipelines, etc., and can effectively extend the service life of valves and pipelines, etc.

[0006] In a possible implementation of the present application, a plurality of interception filters are disposed in the processing chamber, and the plurality of interception filters are arranged at intervals in a direction away from a connection between the input port and the processing chamber.

[0007] In a possible implementation of the present application, a middle portion of the interception filter is far away from the connection between the input port and the processing chamber, and an edge portion of the interception filter is close to the connection between the input port and the processing chamber.

[0009] In a possible implementation of the present application, a sewage discharge channel exists between the edge of the interception filter and the inner wall of the processing chamber.

DETAILED DESCRIPTION

[0023] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0024] This application discloses an integrated manifold, see Figure 1 In some examples, the integrated manifold disclosed in the present application includes a bottom 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, and the manifold body 2 is fixedly mounted on the bottom skid 1.

[0025] The bottom skid 1 here refers to a common base of modular design, which is used to integrate fixed equipment and its auxiliary components to form a functional unit that can be moved as a whole. Its structure is usually welded with steel sections or hollow pipes, with a flat bottom surface and evenly arranged anchor bolts, which are used for connection and fixing.

[0026] The manifold body 2 is a shell, and some equipment and its accessories will be 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.

[0027] There are two processing chambers 3, both of which are arranged inside the manifold body 2. The input port 4 is arranged on the manifold body 2 and is connected to the two processing chambers 3 respectively, and its function is to send the collected products into the processing chambers 3 for processing.

[0028] The pressure relief valve 5 is arranged on the manifold body 2 and connected to the processing chamber 3, and mainly plays a safety role. The pressure relief valve 5 has a limit pressure value. When the pressure in the processing chamber 3 is greater than the limit pressure value, the pressure relief valve 5 automatically opens, which can limit the maximum pressure in the processing chamber 3.

[0029] like Figure 1 As shown in , two processing chambers 3 are respectively equipped with a pressure relief valve 5. Of course, when the two processing chambers 3 are in a communicating state, it is also possible to configure one pressure relief valve 5.

[0030] Figure 1 Two sets of processing chambers 3 and their accessories are arranged on the manifold body 2 in the Figure 1 The manifold body 2 can serve two collection wells at the same time.

[0031] See also Figure 2 The ultrasonic generator 6 is also arranged on the manifold body 2. The two working ends of the ultrasonic generator 6 extend into the two processing chambers 3 respectively to remove bubbles in the collected product. Two output ports 7 are arranged on the manifold body 2 and are connected to the two processing chambers 3 respectively. The two output ports 7 are alternately in an open state, and cooperate with the alternating working state of the processing chambers 3 so that the collected product can be continuously processed.

[0032] In addition, the two processing chambers 3 are also in a connected state, and an interceptor 8 is provided at the connecting point of the two processing chambers 3. The function of the interceptor 8 is to further remove solid impurities in the collected product.

[0033] In combination 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.

[0034] When ultrasound acts on liquid, the liquid alternately compresses and expands 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 ultrasound, these bubbles continue to aggregate and grow in multiple pressure cycles, and eventually rise rapidly to the surface of the liquid due to buoyancy and burst, thereby achieving gas detachment.

[0035] Combined with the contents recorded in the background technology, it can be seen that the products collected entering the processing chamber 3 include water, gas, combustible ice and impurities. The impurities are mainly produced during the mechanical crushing process. Because the entire transportation process is in a low temperature state, the collected products are mainly water, combustible ice, impurities and a small amount of gas.

[0036] The effect of ultrasound on liquid is very obvious, so a large amount of liquid is required in the processing chamber 3. The collected product is first sent into the liquid in the processing chamber 3. At this time, ultrasound is first intervened to defoam the liquid in the processing chamber 3. In this process, the combustible ice will decompose to produce gas and liquid water, impurities will precipitate at the bottom of the processing chamber 3, and gas will accumulate at the bottom of the processing chamber 3.

[0037] 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 will be discharged through the drainage pipe, and the impurities at the bottom of the processing chamber 3 will be discharged through the drain valve at the bottom of the processing chamber 3.

[0038] In some possible implementations, the drain valve at the bottom of the processing chamber 3 is opened at a fixed frequency.

[0039] In some possible implementations, an electric heating heater is disposed inside the manifold body 2 , and the electric heating heater is used to heat the processing chamber 3 to prevent ice from forming inside the processing chamber 3 .

[0040] In some examples, a plurality of interception filters 31 are provided in the processing chamber 3, and the plurality of interception filters 31 are arranged at intervals in a direction away from the connection between the input port 4 and the processing chamber 3. The main function of the interception filter 31 is to intercept impurities and prevent the impurities from entering the subsequent valves and pipelines, causing damage to the valves and pipelines.

[0041] In some examples, the middle portion of the interception filter 31 is far away from the connection between the input port 4 and the processing chamber 3, and the edge portion of the interception filter 31 is close to the connection between the input port 4 and the processing chamber 3, that is, the shape of the interception filter 31 is conical, which can not only increase the interception area of ​​the interception filter 31, but also prevent impurities from accumulating on the interception filter 31.

[0042] In some possible implementations, at least one interception filter 31 is present between the output port 7 and the liquid level in the processing chamber 3 .

[0043] In some possible implementations, there is a drainage channel 32 between the edge of the interception filter 31 and the inner wall of the processing chamber 3, such as Figure 3 shown.

[0044] For some examples, see Figure 4 and Figure 5 The interceptor 8 includes an annular shell 81 and an interception plate group 82. The annular shell 81 is fixedly installed at the connection point of the two processing chambers 3. There are two interception plate groups 82, and the two interception plate groups 82 are symmetrically arranged inside the annular shell 81.

[0045] The interception plate group 82 includes interception plates arranged in sequence, and there are gaps between adjacent interception plates. At the same time, in the direction approaching the middle area of ​​the two interception plate groups 82, the gaps between adjacent interception plates tend to decrease.

[0046] The interception plate has two functions. The first function is to intercept impurities in the gas that are not intercepted by the interception filter 31. The second function is to allow part of the moisture in the gas to condense on the interception plate. The condensed moisture can flush the impurities on the interception plate to avoid blockage of the interception plate group 82.

[0047] In some possible implementations, the direction of the gaps between adjacent intercepting plates is parallel to the direction of gravity.

[0048] For some examples, see Figure 2 , Figure 6 and Figure 7 Each processing chamber 3 is provided with at least two groups of liquid level sensors 9, and the detection height of each group of liquid level sensors 9 is different. The function of the liquid level sensor 9 is to ensure the liquid level in the processing chamber 3, so that the collected product sent 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 liquid to defoam the collected product.

[0049] 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: 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 level 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 the stable value is close to a set value.

[0050] The reason for using two groups of liquid level sensors 9 is that when the feedback from the first group of liquid level sensors 9 is a stable value, preparation for liquid replenishment begins, when the feedback from the second group of liquid level sensors 9 is a stable value, liquid replenishment begins, and when the feedback from the first group of liquid level sensors 9 is a dynamic value, it stops.

[0051] This method reserves start-up time for fluid infusion and sets the start time of fluid infusion, reducing the frequency of fluid infusion.

[0052] When the detection value of the laser signal receiver 92 is a stable value, it means that the liquid level in the processing chamber 3 is too low and liquid replenishment is required.

[0053] by Figure 2 Taking 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, and the effect is the same.

[0054] The input end of the drainage pipe is located below the two groups of liquid level sensors 9 and above at least one interception filter 31 .

[0055] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
