Description

Technical Field

[0001] This utility model relates to the technical field of oil and gas recovery interfaces for chemical storage tanks, and specifically to a corrosion-resistant oil and gas recovery interface for chemical storage tanks. Background Technology

[0002] Chemical storage tanks are containers specifically designed for storing chemicals and are widely used in chemical production to store raw materials, intermediate products, and finished products. When liquids enter the tank, some oil and gas are generated. If this oil and gas is not recovered in time, it will pollute the environment. Therefore, chemical storage tanks are equipped with oil and gas recovery ports at the top, which connect to the interface of oil and gas recovery pipelines. This is used to collect the oil and gas generated in the tank and process it through a recovery system to reduce environmental pollution and achieve reuse of the oil and gas. The use of oil and gas recovery interfaces is of great significance for environmental protection and economic benefits. By recovering and processing oil and gas, the emission of volatile organic compounds (VOCs) can be reduced, thus reducing environmental pollution. At the same time, the recovered oil and gas can be reused, reducing energy consumption and costs and improving economic efficiency. However, when existing oil and gas recovery interfaces are connected to chemical storage tanks, the rubber seals inside the interfaces are easily corroded and damaged by the chemicals in the oil and gas. Utility Model Content

The outer end of the polypropylene protective sleeve is in contact with the inner wall of the chemical oil and gas recovery connector interface via a second oil-absorbing cotton ring. The inner end of the polypropylene protective sleeve is bonded to a first oil-absorbing cotton ring via an adhesive backing layer. A support ring plate is embedded and connected to the upper surface of the polypropylene protective sleeve. A hollow fiber adsorption pad is fixedly attached to the upper surface of the support ring plate.

[0006] Furthermore, a limiting protrusion is provided in the middle of the inner side of the chemical oil and gas recovery connector interface, and a fixing block is connected to the outer end of the chemical oil and gas recovery connector.

[0007] Furthermore, the lower end of the limiting protrusion is welded to the inner wall of the chemical oil and gas recovery connector interface through the inner ring plate; and the rubber sealing gasket is attached to the outer ring surface of the inner ring plate.

[0008] Furthermore, the fixing blocks are connected by fasteners via hinge rods, a venting cavity is provided on the inner side of the inner ring plate, and a pipe connection end is provided at the lower end of the chemical oil and gas recovery connector; and the pipe connection end is connected to the venting cavity.

[0009] Furthermore, the upper surface of the polypropylene protective sleeve is provided with an internal thread groove, and the lower end of the support ring plate is screwed to the internal thread groove through a connecting ring block; and the inner and outer ring surfaces of the connecting ring block are provided with threads.

[0010] Furthermore, the side of the second oil-absorbing cotton ring is bonded to the concave surface of the polypropylene protective sleeve through an adhesive backing layer.

[0011] Furthermore, the inner end of the polypropylene protective sleeve is fixed with anti-detachment protrusions at equal intervals, and the anti-detachment protrusions are hemispherical; and are snapped into the groove of the rubber sealing gasket.

[0012] The beneficial effects of this utility model are as follows: the corrosion-resistant chemical storage tank oil and gas recovery interface of this utility model utilizes a hollow fiber adsorption pad, a support ring plate, a polypropylene protective sleeve, an oil-absorbing cotton ring, and a rubber sealing gasket to form a corrosion-resistant sealing structure for the oil and gas recovery interface. The hollow fiber adsorption pad is tightly attached to the oil and gas inlet of the chemical storage tank, effectively absorbing any residual or adhering oil at the inlet. Simultaneously, the polypropylene protective sleeve and the oil-absorbing cotton rings bonded to the inner and outer sides prevent direct contact between oil and gas and the rubber sealing gasket. This facilitates efficient protection of the sealing gasket within the chemical storage tank's oil and gas recovery interface, reduces the degree of corrosion on the sealing gasket, extends the service life of the sealing gasket, prevents chemical oil and gas leakage due to corrosion damage to the oil and gas recovery interface, and improves the connection tightness and recovery efficiency of the chemical storage tank's oil and gas recovery interface.

[0020] A polypropylene protective sleeve 5 is snapped onto the upper end of the rubber sealing gasket 6. The lower surface of the polypropylene protective sleeve 5 is attached to the rubber sealing gasket 6 through an isolation gasket 51. The outer end of the polypropylene protective sleeve 5 is in contact with the inner wall of the interface of the chemical oil and gas recovery connector 1 through a second oil-absorbing cotton ring 56. The inner end of the polypropylene protective sleeve 5 is bonded to a first oil-absorbing cotton ring 53 through an adhesive backing layer 54. A support ring plate 4 is embedded and connected to the upper end of the polypropylene protective sleeve 5. A hollow fiber adsorption pad 3 is fixedly attached to the upper surface of the support ring plate 4.

[0021] Inside the chemical oil and gas recovery connector 1, a polypropylene protective sleeve 5 and a hollow fiber absorbent pad 3 are fitted and adhered to the surface of a rubber sealing gasket 6. The hollow fiber absorbent pad 3, support ring plate 4, polypropylene protective sleeve 5, oil-absorbing cotton ring, and rubber sealing gasket 6 together form a corrosion-resistant sealing structure for the oil and gas recovery interface. During installation, the hollow fiber absorbent pad 2 is tightly fitted to the oil and gas inlet of the chemical storage tank to absorb any residual or adhering oil at the inlet. Simultaneously, the polypropylene protective sleeve 5 and the oil-absorbing cotton rings bonded to the inner and outer sides prevent direct contact between oil and gas and the rubber sealing gasket 6. This facilitates efficient protection of the sealing gasket inside the chemical storage tank's oil and gas recovery interface, reduces corrosion of the sealing gasket, extends its service life, prevents leakage of chemical oil and gas due to corrosion damage, and improves the connection tightness and recovery efficiency of the chemical storage tank's oil and gas recovery interface.

[0022] In this embodiment, a limiting protrusion 11 is provided in the middle of the inner side of the interface of the chemical oil and gas recovery connector 1, and a fixing block 12 is connected to the outer end of the chemical oil and gas recovery connector 1.

[0023] As a preferred embodiment, the limiting protrusion 11 on the inner side of the interface of the chemical oil and gas recovery connector 1 facilitates the corresponding insertion with the oil and gas pipe port of the chemical storage tank, so that the chemical oil and gas recovery connector 1 is positioned and connected at the oil and gas pipe port of the chemical storage tank, ensuring accurate connection at the oil and gas interface and preventing gas leakage.

[0024] In this embodiment, the lower end of the limiting protrusion 11 is welded to the inner wall of the interface of the chemical oil and gas recovery connector 1 through the inner ring plate 15; and the rubber sealing gasket 6 is attached to the outer ring surface of the inner ring plate 15.

[0025] In a preferred embodiment, the inner ring plate 15 serves to support the limiting protrusion 11. The rubber sealing gasket 6 is made of Teflon material, which has excellent chemical stability, corrosion resistance, sealing performance, high lubricity and non-stick properties, electrical insulation, and excellent anti-aging resistance. It can tightly connect the chemical oil and gas recovery connector 1 to the oil and gas pipe port of the chemical storage tank, preventing oil and gas from flowing out from the interface during transportation.

[0026] In this embodiment, fasteners 14 are connected between the fixing blocks 12 by hinge rods 13, a venting cavity 16 is provided on the inner side of the inner ring plate 15, and a pipe connection end 2 is provided at the lower end of the chemical oil and gas recovery connector 1; and the pipe connection end 2 is connected to the venting cavity 16.

[0027] In a preferred embodiment, the fastener 15 on the outer end of the chemical oil and gas recovery connector 1 is the same fastener used in existing recovery connectors, facilitating quick connection and installation of the chemical oil and gas recovery connector 1 to the oil and gas inlet of the chemical storage tank. The chemical oil and gas recovery connector 1 is connected to the oil and gas recovery pipeline via the pipeline connection end 2, allowing the oil and gas in the chemical storage tank to be discharged into the oil and gas recovery pipeline through the chemical oil and gas recovery connector 1, and finally transported to the oil and gas recovery device.

The hollow fiber adsorption pad 3 uses hollow fiber membrane zeolite adsorption material, which features high adsorption efficiency, non-combustibility, low adsorption temperature rise, and long service life. Its hollow structure provides more absorption space, facilitating the removal of residual or adhering oil at the oil and gas inlet of the chemical storage tank, preventing oil and gas from seeping into the rubber sealing gasket 6. The oil-absorbing cotton rings bonded to the inner and outer sides of the polypropylene protective sleeve 5 both serve an anti-seepage function, effectively protecting the rubber sealing gasket 6 inside the oil and gas recovery interface of the chemical storage tank and reducing the degree of corrosion of the rubber sealing gasket 6 inside the oil and gas recovery interface of the chemical storage tank.

[0030] In this embodiment, anti-detachment protrusions 52 are fixed at equal intervals on the inner end of the polypropylene protective sleeve 5, and the anti-detachment protrusions 52 are hemispherical; and are snapped into the groove of the rubber sealing gasket 6.

[0031] As a preferred embodiment, the anti-detachment protrusion 52 on the inner side of the polypropylene protective sleeve 5 is made of rubber, which facilitates the stable engagement of the polypropylene protective sleeve 5 and the rubber sealing gasket 6, preventing loosening or detachment that could lead to oil and gas contact and corrosion of the rubber sealing gasket 6.
