Description

Technical Field

[0001] The present application relates to the technical field of equipment and pipeline protection, and in particular to a protective layer structure. Background Art

[0002] The outer surfaces of petrochemical equipment and pipelines are generally provided with a protective layer to achieve the purpose of heat preservation and damage protection of the equipment and pipelines.

[0003] At present, the protective layer of the outer surface of petrochemical equipment and pipelines generally includes thermal insulation layer, moisture-proof layer and protective layer, etc. Among them, the most commonly used material for thermal insulation layer and moisture-proof layer is rubber-plastic board, which has the characteristics of non-combustibility, light weight, closed pores and low cost, and can achieve the functions of moisture-proof and thermal insulation; the most commonly used material for protective layer is 304 stainless steel sheet, which has certain strength and corrosion resistance, and can achieve the protection function of thermal insulation layer and moisture-proof layer.

[0004] However, in actual use, as the duration of the cold environment inside the equipment increases, even if the thickness of the insulation layer is increased, the cold inside the equipment will inevitably be transferred to the outer surface of the protective layer, resulting in a large amount of condensation water dripping on the site, causing the management of condensation water to get out of control and bringing safety hazards to the production site. Utility Model Content

[0005] The present application provides a protective layer structure to solve the technical problem in the prior art that the outer surface of the protective layer is prone to produce condensed water dripping on the site, causing the management of the condensed water to be out of control.

[0006] In order to solve the above problems, the present application provides a protective layer structure, which includes:

[0007] Insulation layer;

[0008] A waterproof layer, arranged on one side of the thermal insulation layer;

[0009] The outer protective layer is arranged on a side of the waterproof layer away from the thermal insulation layer, and the outer protective layer is made of foam metal material.

[0010] In some embodiments, the foam metal material is one of a foam aluminum material, a foam nickel material, and a foam aluminum-nickel alloy material.

[0011] In some embodiments, the pore size of the outer sheath is 0.1-10 mm.

[0012] In some embodiments, the porosity of the outer sheath is 75-90%.

[0013] In some embodiments, the thickness of the outer protective layer is 10-50 mm.

[0014] In some embodiments, the insulation layer is made of rubber-plastic material, and the thickness of the insulation layer is 100-200 mm.

[0015] In some embodiments, the waterproof layer is one of a PET film, a PE film, a PC film, a PP film, a PVC film, and a PMMA film, and the thickness of the waterproof layer is 0.01-1 mm.

[0016] In some embodiments, the protective layer structure further comprises:

[0017] The adsorption layer is arranged on the side of the thermal insulation layer facing away from the waterproof layer.

[0018] In some embodiments, the adsorption layer includes activated carbon, and the thickness of the adsorption layer is 5-10 mm.

[0019] In some embodiments, the porosity of the adsorption layer is 20-80%.

[0020] The beneficial effect of the implementation method of the present application is that the protective layer structure provided by the present application includes a thermal insulation layer, a waterproof layer and an outer protective layer. The waterproof layer is arranged on one side of the thermal insulation layer, the outer protective layer is arranged on the side of the waterproof layer away from the thermal insulation layer, and the outer protective layer is a foam metal material. Since the foam metal material has a porous structure, by using the foam metal as the outer protective layer of the protective layer structure, compared with the outer protective layer of the stainless steel sheet, the pore structure of the outer protective layer can be used to collect condensed water in the pores of the foam metal, so as to facilitate subsequent unified treatment, so as to achieve the collection and dripping of condensed water on the outer surface of the protective layer structure, and effectively avoid the management of condensed water at the production site out of control.

[0021] Moreover, since there are generally splicing gaps in the insulation layer, a waterproof layer is provided between the outer protective layer and the insulation layer to effectively prevent condensation water formed on the outer protective layer from penetrating through the splicing gaps of the insulation layer into the surface of the equipment or pipeline and destroying the dry and clean environment of the equipment surface.

[0022] In addition, when the protective layer structure is provided with an adsorption layer on the side of the insulation layer away from the waterproof layer, it can adsorb trace organic matter at the production site and reduce the total amount of VOCs in the air at the site. When the adsorption layer is an activated carbon film layer, its pore structure can also be used to enhance the thermal insulation effect of the protective layer structure on equipment and pipelines.

[0031] See also Figure 1 The protective layer structure provided in the present application comprises a thermal insulation layer 3, a waterproof layer 2 and an outer protective layer 1. The waterproof layer 2 is arranged on one side of the thermal insulation layer 3. The outer protective layer 1 is arranged on the side of the waterproof layer 2 away from the thermal insulation layer 3. The outer protective layer 1 is a foam metal material.

[0032] The protective layer structure provided in the present application can be used to wrap around the outer surface of a chemical reactor or the outer surface of a chemical pipeline, but is not limited thereto. Taking the protective layer structure applied to a chemical reactor as an example, when the protective layer structure is wrapped around the outer surface of the chemical reactor, the thermal insulation layer 3 is located on the side of the protective layer structure facing the chemical reactor, and the outer protective layer 1 is located at a position where the protective layer structure is away from the chemical reactor. Since the foam metal is a special metal material containing foam pores, it is equivalent to the outer protective layer 1 having many foam pore structures. In this way, even if the cold energy transmitted from the chemical reactor forms condensed water in the outer protective layer 1, since the outer protective layer 1 has a pore structure, the condensed water will not gather on the outer surface of the outer protective layer 1 and then drip onto the ground at the site. At the same time, the outer protective layer 1 can use its pore structure to collect the condensed water in the pores of the foam metal for subsequent unified treatment, effectively avoiding the management of condensed water at the production site from getting out of control.

[0033] It should be noted that, by making the outer protective layer 1 a foam metal material, in actual production and use, the pore structure of the foam metal of the outer protective layer 1 can uniformly guide the condensed water to the lowest point of the chemical reactor for uniform collection. For example, a condensed water collection container can be set at the bottom of the chemical reactor, but it is not limited to this. At the same time, the internal pore structure of the foam metal is rich, which increases the contact area between the condensed water and the outside air, so that part of the condensed water temporarily stored in the pore structure of the foam metal can evaporate and diffuse into the air, and the other part can converge to the lowest point of the chemical reactor. And because the pore structure of the foam metal contains air, it is separated into holes, making it less likely for the air on the surface of the chemical reactor to convect and produce heat exchange, further enhancing the thermal insulation performance.

[0034] In the protective layer structure, the waterproof layer 2 is arranged on one side of the thermal insulation layer 3, and the outer protective layer 1 is arranged on the side of the waterproof layer 2 away from the thermal insulation layer 3. It can be understood that the thermal insulation layer 3, the waterproof layer 2 and the outer protective layer 1 in the protective layer structure are stacked in sequence. In the embodiment of the present application, there is no restriction on the specific connection method between the thermal insulation layer 3 and the waterproof layer 2 and between the waterproof layer and the outer protective layer 1. For example, they can be fixed by a combination of dry hanging and bonding.

[0035] The outer protective layer 1 in the protective layer structure is used to protect the thermal insulation layer 3 and the waterproof layer 2. The outer protective layer 1 is made of foam metal material, which can prevent condensed water from gathering on the outer surface of the protective layer and then dripping on the ground. On the other hand, it has a certain strength and can effectively prevent the waterproof layer 2 and the thermal insulation layer 3 from being damaged.

[0036] In some embodiments, the metal foam material of the outer sheath 1 can be one of a foamed aluminum material, a foamed nickel material, and a foamed aluminum-nickel alloy material. By making the outer sheath 1 foamed with aluminum, nickel, or an aluminum-nickel alloy, while meeting the requirements of protection strength and weight, the cost can also be saved. The following embodiments of the present application are described by taking the outer sheath 1 as an example of foamed aluminum, but are not limited thereto.

[0037] In some embodiments, the pore size of the outer sheath 1 can be 0.1-10 mm. The porosity of the outer sheath 1 can be 75-90%. For example, the pore size of the outer sheath 1 can be 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 7 mm, 8 mm, 9 mm, 10 mm, but it is not limited thereto. The porosity of the outer sheath 1 can be 75%, 80%, 82.5%, 85%, 90%. It should be noted that the foam pores formed by foam aluminum are generally irregular and uneven. The pore size of the outer sheath 1 of 0.1-10 mm means that the maximum pore size and the minimum pore size in the pore structure formed by the foam aluminum are between 0.1-10 mm. The preparation process of foam aluminum material is relatively mature, and foam aluminum sheets that meet the requirements of pore size, porosity and thickness can be customized.

[0038] In some embodiments, the thickness of the outer sheath 1 is 10-50 mm. For example, the thickness of the outer sheath 1 can be 10 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 50 mm, but is not limited thereto.

[0039] The insulation layer 3 in the protective layer structure is used to insulate the chemical reactor. In some embodiments, the insulation layer 3 can be made of rubber and plastic materials, for example, the insulation layer 3 can be made of rubber and plastic board. The thickness of the insulation layer 3 can be 100-200 mm. For example, the thickness of the insulation layer 3 can be 100 mm, 120 mm, 150 mm, 180 mm, 200 mm, but is not limited thereto.

[0040] It should be noted that when the insulation layer 3 uses rubber-plastic boards, for chemical equipment of larger size, multiple rubber-plastic boards need to be spliced. By arranging the waterproof layer 2 between the insulation layer 3 and the outer protective layer 1, it is possible to effectively prevent the condensed water of the outer protective layer 1 from penetrating into the inner surface of the chemical equipment through the splicing seams of the rubber-plastic boards in the insulation layer 3, thereby destroying the dry and clean environment of the outer surface of the chemical equipment. The waterproof layer 2 can be a film layer of a polymer material. For example, in some embodiments, the waterproof layer 2 can be one of PET (Polyethylene glycol terephthalate, polyethylene terephthalate) film, PE (Polyethylene, polyethylene) film, PC (Polycarbonate, polycarbonate) film, PP (polypropylene, polypropylene) film, PVC (Polyvinylchloride, polyvinyl chloride) film, and PMMA (Polymethyl Methacrylate, polymethyl methacrylate) film. The thickness of the waterproof layer 2 is 0.01-1 mm. For example, the thickness of the waterproof layer 2 is 0.01 mm, 0.05 mm, 0.1 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, but not limited thereto. When the waterproof layer 2 is one of a PET film, a PE film, a PC film, a PP film, a PVC film, and a PMMA film, and the waterproof layer 2 also has certain flame retardant properties, the protective layer structure provided by the embodiment of the present application is used on the outer surface of the chemical equipment to effectively ensure the safety of the production of the chemical equipment.

[0041] In some implementations, the protective layer structure also includes an adsorption layer 4. The adsorption layer 4 is disposed on the side of the thermal insulation layer 3 away from the waterproof layer 2. That is, the adsorption layer 4, the thermal insulation layer 3, the waterproof layer 2 and the outer protective layer 1 in the protective layer structure are stacked in sequence. When the protective layer structure is wrapped around the outer surface of the chemical equipment, the adsorption layer 4 of the protective layer structure is arranged in contact with the outer surface of the chemical equipment. It can be used to adsorb trace organic matter at the production site, thereby reducing the total amount of VOCs (Volatile Organic Compounds) in the air pores at the production site. When in use, the adsorption layer 4 can directly contact the outer surface of the chemical equipment, so that the adsorption layer 4 can immediately adsorb organic matter when a trace leak occurs in the chemical equipment, thereby avoiding direct contact between the material and other functional layers during leakage.

[0042] See also Figure 2In some embodiments, the adsorption layer 4 includes activated carbon. For example, the adsorption layer 4 may use carbon cloth, which is an activated carbon film. For example, the thickness of the adsorption layer 4 may be 5-10 mm, that is, a 5-10 mm activated carbon film may be used. The thickness of the adsorption layer 4 may be 5 mm, 6 mm, 7 mm, 7.5 mm, 8 mm, 9 mm, 10 mm, but is not limited thereto. In an embodiment of the present application, by making the adsorption layer 4 include activated carbon, the pore structure of the activated carbon may also be used to keep the chemical equipment warm. In some embodiments, the porosity of the adsorption layer 4 is 20-80%. For example, the porosity of the adsorption layer 4 may be 20%, 30%, 40%, 50%, 60%, 70%, 80%, but is not limited thereto.

[0043] The protective layer structure provided in the present application, when used, in some embodiments, the adsorption layer 4 can adopt an activated carbon film with a porosity of 75% and a thickness of 50mm. The thermal insulation layer 3 adopts a 20mm thick closed-cell rubber-plastic board, which is spliced ​​and installed on the outer surface of the chemical reaction equipment that needs to be kept cold, and fixed to the outer facade of the reactor by adhesive. The waterproof layer 2 adopts a 0.5mm thick PE film, and the seams of the waterproof layer 2 need to be staggered to ensure the sealing of the waterproof layer 2. The outer protective layer 1 adopts a foam aluminum plate with a pore size of 9mm, a porosity of 80%, and a thickness of 7mm.

[0044] The protective layer structure provided in the present application, when used, in some embodiments, the adsorption layer 4 can adopt an activated carbon film with a porosity of 50% and a thickness of 100mm. The thermal insulation layer 3 adopts a 15mm thick closed-cell rubber-plastic board or a closed-cell flame-retardant foam board, which is spliced ​​and installed on the outer surface of the chemical reaction equipment that needs to be kept cold, and fixed to the outer facade of the reactor by adhesive. The waterproof layer 2 adopts a 0.5mm thick PVC film, and the seams of the waterproof layer 2 need to be staggered to ensure the sealing of the waterproof layer 2. The outer protective layer 1 adopts a foam aluminum plate with a pore size of 10mm, a porosity of 75%, and a thickness of 16mm.
