Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the present invention provides a high flow rate fluid filtering device 100, the high flow rate fluid filtering device 100 is used to be connected in series in a target pipeline 200, the filtering device 100 comprises a first cylinder 110 and a plurality of adsorption baffles 120.

The first cylinder 110 has an inlet 111 and an outlet 112, the inlet 111 has a cross-sectional size larger than that of the outlet 112, and a plurality of adsorption baffles 120 are provided at intervals along an axial direction of an inner wall of the first cylinder 110. The cross-sectional dimension of the inlet 111 of the first cylinder 110 is larger than that of the outlet 112, so that after the fluid enters the first cylinder 110 from the inlet 111, the velocity of the fluid in the first cylinder 110 is reduced, and thus the time of the fluid in the first cylinder 110 is prolonged, which is beneficial for the plurality of adsorption baffles 120 to adsorb impurities in the fluid.

A through hole 121 is formed at the center of the adsorption baffle 120, the diameter of the through hole 121 is matched with the inner diameter of the target pipe 200, and an impurity adsorption layer (not shown) is formed on the adsorption baffle 120.

It should be noted that the aperture of the through hole 121 may be the same as the inner diameter of the target pipe 200, or the aperture of the through hole 121 may be slightly larger or slightly smaller than the inner diameter of the target pipe 200. By setting the hole diameter of the through hole 121 to match the inner diameter of the target pipe 200, the flow rate of the fluid in the target pipe 200 can be ensured. The adsorption baffle 120 is provided with an impurity adsorption layer for adsorbing impurities in the fluid and preventing the impurities from being washed out by the high-speed fluid in the filtering device.

It should be noted that the high-flow-rate fluid may include a high-flow-rate gas and a high-flow-rate liquid, and in this embodiment, the high-flow-rate fluid is exemplified by the high-flow-rate gas.

In this embodiment, since the high-flow-rate fluid in the target channel 200 enters the first cylinder 110 through the inlet 111 of the first cylinder 110 and the aperture of the through hole 121 of the adsorption baffle 120 matches the inner diameter of the target channel 200, the flow rate of the fluid in the target channel 200 does not change. The inner wall of the first cylinder 110 is provided with a plurality of adsorption baffles 120 at intervals along the axial direction thereof, and when the fluid flowing into the first cylinder 110 meets the plurality of adsorption baffles 120, the flow rate of the fluid is reduced, and the cross-sectional dimension of the inlet 111 of the first cylinder 110 is larger than that of the outlet 112, the velocity of the fluid in the first cylinder 110 is further reduced, so that the time of the fluid in the first cylinder 110 is lengthened. Because the adsorption baffle 120 is provided with the impurity adsorption layer, the impurity adsorption layer can adsorb the impurity in the fluid on the adsorption baffle 120.

The high-flow-rate fluid filtering device of the embodiment can filter the high-speed fluid in the target pipeline on the premise of not reducing the flow rate of the fluid in the target pipeline. Meanwhile, the pressure drop of the filtering device in high-speed fluid is small, the overhigh pressure difference at two ends of the filtering device is avoided, and the safety and the economical efficiency of a target pipeline are improved.

Illustratively, the impurity-adsorbing layer is an electrostatic adsorbing layer. The electrostatic adsorption layer can be made of adsorption plastic, and the adsorption plastic is fixed at the adsorption baffle 120 and is externally connected with a high-voltage electrostatic generator. Of course, other materials may be used for the electrostatic adsorption layer, and this embodiment is not particularly limited. The electrostatic adsorption layer may be provided on the side of the adsorption shutter 120 facing the inlet 111, on the side of the adsorption shutter 120 facing the outlet 112, or on both the side of the adsorption shutter 120 facing the inlet 111 and the side of the adsorption shutter 120 facing the outlet 112.

Illustratively, as shown in fig. 1, the suction baffle 120 includes a suction portion 122 and a guide portion 123. A first end of the adsorption part 122 is connected to an inner wall of the first cylinder 110, and the guide part 123 extends from a second end of the adsorption part 122 to be inclined toward the inlet 111. The guide portion 123 extends obliquely from the second end of the adsorption portion 122 toward the inlet 111, and may guide impurities in the high flow rate fluid entering the first cylinder 110 to the surface of the adsorption baffle 120.

Illustratively, as shown in fig. 1, the first cylinder 110 gradually decreases in size from the inlet 111 to the outlet 112. Further preferably, in the present embodiment, the first cylinder 110 is tapered. Accordingly, the cross-section of the adsorption baffle 120 is circular.

Illustratively, as shown in fig. 1 and 2, a plurality of through holes 113 are formed on the inner wall of the first cylinder 110 corresponding to the adsorption baffle 120. The plurality of through holes 113 may discharge the impurities adsorbed by the adsorption baffle 120 out of the first cylinder 110, reducing the replacement frequency of the filter device 100.

Illustratively, as shown in fig. 1 and 2, the filter device 100 further includes a second cylinder 130, and the second cylinder 130 is disposed outside the first cylinder 110. Wherein, an impurity collecting chamber 140 is formed between the second cylinder 130 and the first cylinder 110. The impurity collecting chamber 140 may serve to store impurities discharged from the plurality of through-holes 113. In this embodiment, the second cylinder 130 is cylindrical, and may also be in other shapes, which is not specifically limited in this embodiment and can be selected according to actual needs.

For example, as shown in fig. 1 and fig. 2, a pressure relief pipeline 150 is disposed on the second cylinder 130, and a pressure relief valve 151 is disposed on the pressure relief pipeline 150. The pressure relief valve 151 may be a solenoid valve or a manual valve. The pressure relief valve 151 may control the pressure within the impurity collection chamber 140. When the filtering device 100 needs to be cleaned, the interior of the impurity collecting chamber 140 is depressurized by using an electromagnetic valve or a manual valve opening mode, the adsorption baffle 120 is purged by using high-pressure fluid in the target pipeline 200, and the adsorbed impurities are blown to the interior of the impurity collecting chamber 140 through the plurality of through holes 113 to be stored, so that the self-cleaning function of the filtering device 100 is realized.

In the above embodiment, the filtering apparatus 100 can realize self-cleaning by the system pressure itself, and frequent replacement of the filtering apparatus 100 is avoided, thereby improving the filtering efficiency, reducing the replacement frequency, and improving the safety of the system operation.

Illustratively, as shown in fig. 1, a plurality of adsorption baffles 120 are equally spaced along the axial direction of the inner wall of the first cylinder 110. Of course, the plurality of adsorption baffles 120 may also be distributed at unequal intervals along the axial direction of the inner wall of the first cylinder 110, and this embodiment is not particularly limited, and may be selected according to actual needs.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
