Description

Technical Field

[0001] The present application relates to the technical field of chemical equipment, and in particular to a washing tower. Background Art

[0002] The scrubber is a new type of gas purification equipment, which is improved on the basis of the floating packing layer gas purifier and is widely used in pre-treatment of industrial waste gas purification, dust removal, etc.

[0003] In the related art, the outer shell of the washing tower is made of FRP or PP. Since the FRP washing tower is a fiber winding device, it is expensive due to the mold specification restrictions and the use of good resin and glass fiber. If a washing tower is made of PP sheet, although the price is low, it is easily aged by ultraviolet rays, which greatly reduces its service life. In addition, it also needs to reach a certain thickness to ensure its strength during use, so the thickness of the equipment is much greater than that of the FRP washing tower.

[0004] The washing tower shells made of the above two materials have material disadvantages or cost problems, which are not conducive to the development of the enterprise.

[0005] In order to solve the problems in the related art, a washing tower is provided. Utility Model Content

[0006] In order to solve the problem in the related art that the outer shell of the washing tower is made of filament-wound fiberglass or PP sheet by rolling and welding, which is too thick and expensive and has a short service life, the present application provides a washing tower.

[0008] A washing tower comprises a washing tower body and a washing tower shell. The washing tower shell comprises a glass fiber reinforced plastic layer and a reinforcement layer which are sequentially arranged from the outside to the inside. A protective piece for preventing ultraviolet rays is arranged on the glass fiber reinforced plastic layer.

[0009] By adopting the above technical solution: using FRP as external support and reinforcing layer as inner lining, the use of FRP is effectively reduced, which is beneficial to cost control. At the same time, protective parts are arranged on the outer surface of the FRP layer, which can effectively reduce the direct exposure of ultraviolet rays to the FRP layer, reduce the risk of aging of the washing tower shell, and extend the service life of the washing tower.

[0010] Preferably, the reinforcement layer is a PP board layer.

[0011] By adopting the above technical solution: the PP board layer has good heat resistance, high mechanical strength, excellent chemical stability, strong corrosion resistance, long service life, high temperature resistance and pressure resistance, etc. At the same time, the PP board has outstanding advantages in energy saving and material saving. The material consumption per unit area of ​​the PP board can be reduced by one half or more, which is beneficial to saving resources. The lighter weight of the PP board can also reduce the load.

[0012] Preferably, the protective member is an anti-ultraviolet gel coat.

[0013] By adopting the above technical solution: coating the anti-ultraviolet gel coat on the outer surface of the glass fiber reinforced plastic layer, direct ultraviolet rays can be effectively blocked, which is of great significance for protecting the PP board layer arranged behind the glass fiber reinforced plastic layer.

[0014] Preferably, a needle cloth felt is provided on the PP board layer for reducing the risk of delamination of the washing tower shell due to thermal expansion and contraction.

[0015] By adopting the above technical solution: since the internal temperature of the washing tower will rise when it is working and the temperature will slowly drop when it is closed, and the heat radiation capacity of each plate layer is different, it will cause thermal expansion and contraction between the plate layers, so that some parts of the plate layer are squeezed and broken. The needle cloth felt has the function of thermal insulation and can absorb a certain amount of heat, effectively reducing the risk of delamination of the washing tower shell due to thermal expansion and contraction.

[0016] Preferably, a resin adhesive layer is provided between the fiberglass layer and the PP board layer.

[0017] By adopting the above technical solution: the resin can provide strong adhesion, increase viscosity and stability, so that the FRP layer and the PP board layer can be connected together and maintain overall fixation. At the same time, the resin glue layer prepared in this way can also fill the defects and cracks on the surface of the PP board layer and the FRP layer.

[0018] Preferably, the adhesive layer is a resin adhesive layer.

[0019] By adopting the above technical solution: the resin can provide strong adhesion, increase viscosity and stability, and the resin glue layer prepared in this way can also fill the defects and cracks on the surface of the PP board layer and the fiberglass layer.

[0020] Preferably, the resin adhesive layer is filled with a glass fiber mesh.

[0021] By adopting the above technical solution: the provision of the glass fiber mesh is beneficial to strengthening the overall strength of the outer shell of the washing tower.

[0022] Preferably, a steel frame for supporting the outer shell of the washing tower is provided inside the washing tower body.

[0023] By adopting the above technical solution: the steel frame can support the shape and fix the structure of the washing tower shell.

[0024] Preferably, the thickness of the reinforcement layer is 8-10 mm, and the wall thickness of the fiberglass reinforced plastic layer gradually changes from top to bottom and is 8-3 mm.

[0025] By adopting the above technical solution: setting the thickness of the PP board layer to 8-10mm, and the wall thickness of the glass fiber reinforced plastic layer gradually changing from top to bottom to 8-3mm, the washing tower shell can reduce weight while meeting safety requirements.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The present application uses FRP as external support and PP board as inner lining, which effectively reduces the use of FRP layer, is conducive to cost control, and at the same time, a protective piece is arranged on the outer surface of the FRP layer, so that the ultraviolet rays can be effectively reduced from penetrating the FRP layer to the PP board layer, reducing the risk of aging of the PP board layer and extending the service life of the washing tower;

[0028] 2. This application can effectively reduce the risk of delamination and rupture of the washing tower shell due to thermal expansion and contraction by adding a needle cloth felt on the PP board layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. Example

[0034] The present application embodiment discloses a washing tower, referring to Figure 1 , Figure 2 and Figure 3, including a washing tower body 1 and a washing tower shell 2, wherein the washing tower shell 2 includes a glass fiber reinforced plastic layer 21 and a PP board layer 22 arranged in sequence from the outside to the inside, the glass fiber reinforced plastic layer 21 acts as an outer support, and the PP board layer 22 acts as an inner lining, which effectively reduces the use of glass fiber reinforced plastic and reduces the manufacturing cost. At the same time, in order to reduce the damage caused by ultraviolet rays to the glass fiber reinforced plastic layer 21 and the PP board layer 22, a protective part is installed on the side of the glass fiber reinforced plastic layer 21 away from the PP board layer 22. In this embodiment, it is an anti-ultraviolet gel coat 211, which effectively isolates the radiation of ultraviolet rays and is beneficial to extending the service life of the washing tower shell 2.

[0035] When the washing tower is turned on, its internal temperature will continue to rise, and the heat radiation capacity of each plate layer is different, which will cause thermal expansion and contraction between the plates, so that some parts of each plate layer will be squeezed or even broken. In order to reduce the risk of delamination and rupture of the washing tower shell 2 due to thermal expansion and contraction, refer to Figure 2 and Figure 3 A needle cloth felt 221 is installed on the side of the PP board layer 22 close to the glass fiber reinforced plastic layer 21. The needle cloth felt 221 has the function of heat preservation and heat insulation, and can absorb a certain amount of heat, which is conducive to maintaining the uniform contraction or expansion of heat conduction between the board layers.

[0036] In order to maintain the connection and fixation between the PP plate layer 22 and the glass fiber reinforced plastic plate layer, refer to Figure 2 and Figure 3 A resin glue layer 3 is also installed between the FRP layer 21 and the PP board layer 22. Resin, as a material, can provide strong adhesion, increase viscosity and stability. The resin glue layer 3 made of resin makes the connection between the FRP and the PP board layer 22 more firmly, and can also fill the defects and cracks on the surface of the PP board layer 22 and the FRP layer 21.

[0037] In order to further enhance the overall strength of the washing tower shell 2, refer to Figure 2 and Figure 3 A glass fiber mesh 31 is also filled in the resin adhesive layer 3, and a steel frame 11 is installed between the inside of the washing tower body 1 and the washing tower shell 2. The steel frame 11 can not only provide support for the washing tower shell 2, but also fix it.

[0038] In order to realize the lightweight design of the washing tower shell 2 and meet certain safety requirements, the wall thickness of the glass fiber reinforced plastic layer 21 gradually decreases from 8-3 mm from top to bottom, and the thickness of the PP board layer 22 is 10 mm.

[0039] The working process and implementation principle in Example 1 are as follows: the PP board layer 22 is installed on the FRP layer 21 as an inner lining, and a resin glue layer 3 filled with a glass fiber mesh 31 is added between the FRP layer 21 and the PP board layer 22, so that the PP board layer 22 is fixedly connected and fixed to the FRP layer 21. In addition, in order to reduce the risk of delamination of the washing tower shell 2 due to thermal expansion and contraction, a needle cloth felt 221 is also installed on the side where the PP board layer 22 is connected to the FRP layer 21, and then an anti-ultraviolet gel coat 211 is applied on the outer surface of the FRP layer 21 to effectively reduce the damage caused by direct ultraviolet rays. Finally, the entire washing tower shell 2 is installed on the steel frame 11, and the wall thickness of the FRP layer 21 is gradually reduced from 8-3mm from top to bottom, wherein the thickness of the PP board layer 22 is 10mm, so that the washing tower shell 2 is lightweight while meeting certain safety requirements.

[0040] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
