Although some equipment can adapt to the changes in working conditions by closing or opening a certain number of swirl tubes (or swirl tubes) inside the equipment, it is inconvenient to operate on site.

[0014] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0015] like Figure 1 As shown, an embodiment of the utility model proposes a multi-tube bundle cyclone separator, including a separator body 1, wherein the separator body 1 is divided into a sedimentation chamber 4, a separation chamber 5 and an exhaust chamber 6 by a first mounting plate 2 and a second mounting plate 3, the separation chamber 5 is between the first mounting plate 2 and the second mounting plate 3, a plurality of tubular cyclone tubes 7 are arranged between the first mounting plate 2 and the second mounting plate 3, the exhaust chamber includes a plurality of partition chambers 8, each partition chamber 8 is provided with an outlet, the outlet of each partition chamber 8 is connected to a cutting mechanism, and each partition chamber is correspondingly connected to at least one cyclone tube 7.
[0016] When the utility model is in use, if it is in the initial stage of gas extraction, the gas flow is abundant, the gas enters from the inlet of the separator body 1, and then enters the separation chamber 5. Since a plurality of cyclone tubes 7 are provided in the separation chamber 5, the gas will enter the cyclone tubes 7 for separation. When the cyclone tubes are separating, the sand and gravel solids therein are settled downward into the sedimentation chamber 4, and the separated gas flows to the top, and finally enters the exhaust chamber 6, and is discharged through the exhaust pipe 9 connected to the exhaust chamber 6; after a period of extraction, the gas gradually decreases and the flow gradually decreases. At this time, the shut-off valve 10 of the exhaust pipe 9 connected to one or more of the separation chambers 8 can be closed to isolate these separation chambers 8. At this time, the gas will be discharged from the remaining chambers. At this time, due to the change in the number of cyclones involved in the work, the gas flowing through each cyclone can be maintained at the initial level, ensuring the separation effect of the cyclone, and maintaining appropriate pressure loss and wear.
[0017] Furthermore, the separation chamber 5 is divided into a plurality of separation chambers 8 by a partition plate 11. Figure 1 The number of the partition plates 11 is three, the number of the partition chambers 8 is four, and the number of cyclones connected in the partition chambers 8 in this example is equal. Specifically, the partition chamber 8 of the utility model is divided by the partition plates 11, and can be divided into multiple partition chambers 8 as needed, wherein the partition can be divided by the partition plates 11, and when the partition is divided by the partition plates 11, the volume of each partition chamber 8 is ensured to be equal, so that it is convenient to calculate the flow rate of the gas in the remaining partition chamber 8 after the partition chamber 8 is closed.
[0018] Furthermore, each partition cavity is connected to an exhaust pipe 9 at the end, the cut-off mechanism is connected to the exhaust pipe 9, and the end of the exhaust pipe 9 is connected to a main exhaust pipe 12. Specifically, the end of the exhaust pipe 9 of the utility model is connected to a main exhaust pipe 12, so that no matter which partition cavities 8 are closed, when the gas flows out, the outlet is always at the end of the main exhaust pipe 12.
[0019] Furthermore, each partition chamber is connected to an exhaust pipe 9 at the end, the cut-off mechanism is connected to the exhaust pipe 9, the end of the exhaust pipe 9 is connected to a main exhaust pipe 12, and an electronic flow meter 13 is provided on the main exhaust pipe 12. Specifically, the electronic flow meter 13 of the utility model can use a flow meter to measure the actual gas volume, so as to determine whether to close one or more partition chambers 5, that is, to obtain the expected number of cyclone tubes participating in the work.
[0020] Furthermore, the cut-off valve 10 is an electronic ball valve or an electronic gate valve. Specifically, the cut-off valve 10 of the utility model adopts a ball valve, which can realize the automatic isolation and closure of the partition chamber 8 after being connected to the controller, making the utility model faster and more convenient when used.
[0021] The multi-tube bundle cyclone separator involved in the utility model can also realize flow regulation according to the gas flow that needs to be processed every day, as shown in the following embodiments:
[0022] Embodiment 1:
[0023] S1: Determine the gas flow rate that needs to be processed every day as V (such as 1 million cubic meters / day), and determine the flow rate processed by a single cyclone every day as C (such as a rated flow rate of 50,000 cubic meters / day) according to the model and volume of the cyclone;
[0024] S2: Determine the required number of cyclones as V / C (100 / 5=20), and install the cyclones of this number in the separator body;
[0025] S3: Divide the cyclones into 5 groups, each group includes 4 cyclones, and each group of cyclones is connected to a partition cavity;
[0026] S4: When performing gas treatment, in the initial stage, ensure that 5 groups of cyclones are turned on, obtain flow signals through the electronic flow meter 13, and transmit the flow signals to the controller connected to the separator, and judge whether the gas flow rate is less than the preset value through the controller; if the preset value is a, in the initial stage, the value detected by the electronic flow meter 13 will be greater than a. As time goes by, the electronic flow meter 13 will detect that the flow value is less than a. At this time, stop one group of cyclones. At this time, the flow value in the total exhaust pipe will be greater than a. After waiting for a period of time, the flow value in the total exhaust pipe will reach below a again. At this time, turn off another group of cyclones, and repeat the above process until only one group of cyclones is working.
[0027] Embodiment 2:
[0028] S1: Determine the gas flow rate that needs to be processed every day as V (such as 1.2 million cubic meters / day), and determine the flow rate processed by a single cyclone every day as C (such as a rated flow rate of 50,000 cubic meters / day) according to the model and volume of the cyclone;
[0029] S2: Determine the required number of cyclones as V / C (120 / 5=24), and install the cyclones of this number in the separator body;
[0030] S3: According to the actual gas flow rate D to be processed (such as 1 million cubic meters / day), 5 groups of 4 cyclones and 3 groups of 2 cyclones are included respectively;
[0031] S4: When processing the gas, ensure that 8 groups of cyclones are turned on, obtain flow signals through the electronic flow meter 13, and transmit the flow signals to the controller connected to the separator, and judge whether the gas flow rate is less than the preset value through the controller; if the preset value is a, in the initial stage, the value detected by the electronic flow meter 13 will be greater than a. As time goes by, the electronic flow meter 13 will detect that the flow value is less than a. At this time, in order from small to large, that is, stop one group of two cyclones each time. When the two groups of cyclones (i.e., 3 groups) are stopped, because the gas flow rate decreases faster at this time, when the gas flow value is less than a again, stop one group of 4 cyclones each time, and repeat the above process until only one group of 4 cyclones is still working.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
