Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
A fiber demisting device comprises a vertical demisting tower 1, wherein a glass fiber filler 11 for condensing water vapor is arranged in the demisting tower 1; the side of the bottom of the demisting tower 1 is provided with a tail gas inlet 12, the top of the demisting tower 1 is provided with a first tail gas outlet 13, the other side of the bottom of the demisting tower 1 is provided with a first liquid collecting pipe 14, and the first liquid collecting pipe 14 is connected to the liquid collecting tank 3. First tail gas outlet 13 back is connected to condenser 2 through the pipeline be provided with cooling water inlet 21 and cooling water outlet 22 on the condenser 2 respectively the top of condenser 2 is provided with second tail gas outlet 23, and the bottom is provided with second collecting tube 24, second collecting tube 24 is connected to collecting tank 3.
The height of the demisting tower 1 is 4.5 m. The diameter was 1.5 m.
In this embodiment, tail gas enters from tail gas inlet 12 of defogging tower 1, and then comes out from first tail gas outlet 13 at the top of defogging tower 1, lets in condenser 2, and steam condenses into the liquid drop on the glass fiber filler earlier, and the bottom that drips after gathering together gathers into rivers and retrieves to collecting tank 3 in, uses as the absorption liquid of burning furnace. The cooling area of the condenser 2 added at the second tail gas outlet 23 is about 50m2And the condenser 2 is filled with 5 ℃ cooling water for cooling, and can continue to condense and remove residual water vapor in tail gas, so that a large amount of white mist does not exist at the second tail gas outlet 23, and the tail gas emission reaches the standard.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the products of the present invention are usually placed when used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element to which the term refers must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
