Description

Technical Field

[0001] The utility model relates to the field of wet electrostatic precipitators, in particular to a novel gas-water separation device for a wet electrostatic precipitator. Background Art

[0002] The wet electrostatic precipitator utilizes an electric field. When the exhaust gas passes through the electric field, all dust droplets, PM2.5, etc. will move to the anode under the action of the electric field force, thereby achieving the purpose of dust removal.

[0003] The wet electrostatic precipitator uses the top covering spray flushing form to remove the dust accumulated on the anode tube. The violent flushing of the flushing water flushes the dust on the anode tube wall into the ash collecting tank at the bottom.

[0004] There are two types of flue gas flow directions in a wet electrostatic precipitator: from top to bottom and from bottom to top. When the flue gas flow direction is from top to bottom, the flushing water and flue gas flow in the same direction. After the turbid flue gas is purified by the electric field, it collides with the dripping flushing water again, resulting in secondary entrainment, causing dust emissions to exceed the standard.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a novel wet electrostatic precipitator gas-water separation device, which comprises at least one set of receiving plate groups extending along the flow direction of a fluid, wherein the fluid is a gas-liquid mixture (flue gas mixed with liquid); and the receiving plate group comprises a plurality of receiving plates 1 located in the same plane, and the plane is arranged at a predetermined angle to the flow direction of the fluid; as shown in the present embodiment, the receiving plate group is provided with two groups, and the plane where each set of receiving plate groups is located is arranged perpendicular to the flow direction of the fluid ( Figure 1 and Figure 2 shown),

[0024] Each receiving plate 1 includes a flow-blocking surface 100 with a predetermined angle to the flow direction of the fluid. The flow-blocking surface 100 is used to receive the fluid and is mainly used to complete the gas-liquid separation work. In order to better undertake the work, the flow-blocking surface 100 in this embodiment is perpendicular to the flow direction of the fluid. The specific separation principle is that after the smoke in a gas-liquid mixed state is blown to the flow-blocking surface 100, the liquid will be retained on the flow-blocking surface 100 and gather to form a liquid surface, and the liquid surface flows out of the device under the guidance of the flow-blocking surface 100, while the gas moves downward through the layers of receiving plates 1 under the action of air pressure to achieve the gas-liquid separation effect. Of course, the shape of the flow-blocking surface 100 is not limited, and it can be a planar structure in this embodiment, or a "v"-shaped structure that optimizes the guidance effect.

[0025] A plurality of receiving plates 1 in the same group are arranged at equal intervals, and the gaps between the receiving plates 1 constitute channels for smoke flow.

[0026] In this example, in order to increase the receiving area of ​​the receiving plate 1 for the fluid, a flat plate structure is adopted. Of course, in order to ensure the flow guidance of the receiving plate 1 and prevent the liquid from flowing downward, baffles 11 are provided on both sides of the blocking surface to block the liquid and drive it to move along the extension direction of the receiving plate 1. Furthermore, in order to increase the receiving area of ​​the receiving plate 1 for the fluid and ensure that the receiving plate 1 can receive smoke as much as possible, the baffle 11 of the present application adopts the following structure, the baffle 11 includes a blocking portion 101 arranged perpendicular to the blocking surface 100 and a folding wing 102 arranged at an obtuse angle to the flow direction of the fluid; the folding wings 102 on both sides of the blocking surface are symmetrically arranged. Figure 1 As shown, the folding wings 102 are symmetrically arranged to form a gathering structure (wide at the top and narrow at the bottom). On the one hand, the folding wings 102 increase the overlap area between the receiving plates 1 and the receiving area of ​​a single receiving plate 1. In addition, the folding wings 102 arranged at an angle also have the effect of gathering and guiding flow.

[0027] Furthermore, in order to increase the receiving area of ​​the receiving plate 1 for the fluid, two groups of adjacent receiving plates 1 are staggered.

[0028] In addition, the two adjacent upper and lower receiving plates 1 are fixedly supported by the connecting piece 2. Of course, the end portion can also be fixedly connected to the inside of the dust collector, in which case the connecting piece 2 plays an auxiliary supporting role. In this embodiment, the connecting piece 2 is a support rod, one end of which is fixedly connected to the outer wall of the baffle 11 of the receiving plate 1 located at the upper position, and the other end is fixedly connected to the inner wall of the baffle 11 of the receiving plate 1 located at the lower position, and both are fixedly connected by bolts. The above structure simplifies the structure of the connecting piece 2 and avoids affecting the circulation of airflow.

[0029] See also Figure 4 In another embodiment, the connecting member 2 is a support rod, one end of which is fixed to the outer wall of the baffle 11 of the receiving plate 1 located at the upper position, and the other end is fixed to the outer wall of the baffle 11 of the receiving plate 1 located at the lower position; the baffle 11 of the receiving plate 1 located at the lower position is provided with a positioning hole 3 for positioning the connecting member 2; during installation, the connecting member 2 passes through the positioning hole 3. The positioning hole 3 increases the stability of the connecting member 2, increases its connection strength, and prevents the connecting member 2 from rotating around the bolt fixing point.

[0030] In summary, the utility model provides a new type of wet electrostatic precipitator gas-water separation device, including at least one group of receiving plate groups extending along the flow direction of the fluid, wherein the fluid is a gas-liquid mixture (flue gas mixed with liquid); and the receiving plate group includes a plurality of receiving plates located in the same plane, and the plane is set at a predetermined angle to the flow direction of the fluid; the receiving plate group is provided with two groups, and the plane where each group of receiving plate groups is located is perpendicular to the flow direction of the fluid, and each receiving plate includes a flow-blocking surface at a predetermined angle to the flow direction of the fluid, and the flow-blocking surface is used to receive the fluid, and is mainly used to complete the gas-liquid separation work. In order to better undertake the work, the flow-blocking surface is perpendicular to the flow direction of the fluid. The specific separation principle is that after the flue gas in a gas-liquid mixed state is blown to the flow-blocking surface, the liquid will be retained on the flow-blocking surface and gather to form a liquid surface, and the liquid surface flows out of the equipment under the guiding action of the flow-blocking surface, and the gas moves downward through the layers of receiving plates under the action of air pressure to achieve a gas-liquid separation effect. The utility model can receive mixed flue gas through the baffle surface, achieve gas-liquid separation effect, effectively solve the problem of secondary entrainment, and improve the working quality of the dust collector.
