Technical Field

[0001] This utility model relates to the field of chemical equipment, specifically a high-efficiency titanium separation tower. Background Technology

[0002] Separation towers are key equipment used in the chemical industry for gas-liquid or liquid-liquid separation, and are widely used in petrochemical, pharmaceutical, and environmental protection fields. Traditional separation towers are mostly made of stainless steel or carbon steel, but in highly corrosive media, such as strong acids, strong alkalis, or chlorine-containing media, these materials have insufficient corrosion resistance, resulting in short equipment life and high maintenance costs. Titanium, due to its excellent corrosion resistance, high strength, and lightweight properties, has gradually become an ideal material for the manufacture of separation towers. However, titanium is difficult to process, and the welding and heat treatment processes are demanding. There is a lack of systematic manufacturing of titanium separation towers in the current technology.

[0003] Therefore, it is necessary to propose a highly efficient titanium separation tower. Utility Model Content

[0011] Preferably, a flange assembly is welded between the lower end cap and the cylinder, and the flange assembly is a middle flange made of carbon steel forgings.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0013] Beneficial effects:

[0014] By constructing a tower body entirely composed of packing material and liquid distributors, with liquid distributors installed above the packing material to evenly distribute the liquid onto the packing surface, the effective contact area for mass and heat transfer is maximized.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] like Figure 1 ;

[0019] A high-efficiency titanium separation tower includes a skirt 1, and a tower body mechanism 100 is provided on the top of the skirt 1. The tower body mechanism 100 is the main structure of the separation tower.

[0020] The tower body structure 100 includes an upper end cap 9, a cylindrical body 6, a lower end cap 10, and a jacketed cylindrical body 2. The jacketed cylindrical body 2 is located on top of the skirt support 1, the lower end cap 10 is located on top of the jacketed cylindrical body 2, the cylindrical body 6 is located on top of the lower end cap 10, and the upper end cap 9 is located on top of the cylindrical body 6. The welding of the tower body structure 100 adopts a welding method of argon arc welding for the root pass followed by manual welding and automatic submerged arc welding for the top pass. The titanium cladding welding of the tower body structure 100 is controlled using argon arc welding technology and employs high purity... Argon gas protection with a purity of over 99.998% is used to protect the weld front side with two protective covers, a main cover and a secondary cover. The main cover is used to protect the weld pool, and the secondary cover is used to cool and protect the heat-affected zone. Argon gas protection is used on the tail side until the temperature of the entire weld and heat-affected zone drops below 200 degrees Celsius. The upper head 9, the cylinder 6 and the lower head 10 are all made of titanium composite plate. The bottom of the jacket cylinder 2 is provided with a jacket head 11. Both the jacket cylinder 2 and the jacket head 11 are made of carbon steel.

[0021] The upper three sections of the cylinder 6 are filled with corrugated plate packing 7, which is made of 0Cr17Ni12Mo6 material. The lower section of the cylinder 6 is filled with Pall ring packing 5, which is also made of 0Cr17Ni12Mo6 material. Each section of corrugated plate packing 7 and each section of Pall ring packing 5 are equipped with a liquid distributor 8. There are four liquid distributors 8 in total, which evenly distribute the liquid to the surface of the packing, ensuring that the effective contact area for mass and heat transfer is maximized and avoiding channeling and deviation. To reduce liquid surface fluctuations and improve distribution stability, a guide plate 3 is added inside the jacketed cylinder 2. The guide plate 3 is made of carbon steel and forms an S-shaped medium channel to improve heat exchange efficiency. A jacket is added to the lower half of the cylinder 6. The jacket is equipped with a heat medium inlet and outlet. The working temperature of the separation tower is controlled by circulating coolant or heating medium. The jacket and the cylinder 6 are connected by a combination of laser welding and submerged arc welding to ensure sealing. A flange assembly 4 is welded between the lower head 10 and the cylinder 6. The flange assembly 4 is a middle flange made of carbon steel forging.

[0022] The working principle of this utility model is as follows: A tower body mechanism 100 is set on the top of the skirt seat 1. The tower body mechanism 100 includes an upper end cap 9, a cylinder 6, a lower end cap 10, and a jacketed cylinder 2. The upper three sections of the cylinder 6 are filled with corrugated plate packing 7, and the lower section of the cylinder 6 is filled with Pall ring packing 5. A liquid distributor 8 is set above each section of corrugated plate packing 7, and a liquid distributor 8 is also set above the Pall ring packing 5. The liquid distributor 8 consists of four sections, which evenly distribute the liquid to the surface of the packing, ensuring that the effective contact area for mass and heat transfer is maximized and avoiding channeling. To mitigate flow deviation and wall flow phenomena, reduce liquid surface fluctuations, and improve distribution stability, a guide plate 3 made of carbon steel is added inside the jacketed cylinder 2. The guide plate 3 forms an S-shaped medium channel, improving heat exchange efficiency. A jacket is added to the lower half of the cylinder 6, with a heat medium inlet and outlet. The operating temperature of the separation tower is controlled by circulating coolant or heating medium. A combination of laser welding and submerged arc welding is used between the jacket and the cylinder 6 to ensure sealing. The 100 titanium cladding of the tower structure is welded using argon arc welding technology with argon gas of purity higher than 99.998%. For protection, two protective covers are installed on the front side of the weld. The main cover protects the weld pool, while the secondary cover cools and protects the heat-affected zone. Argon gas protection is used on the tail side until the temperature of the entire weld and heat-affected zone drops below 200 degrees Celsius. When welding the tower structure 100, the base layer is welded using submerged arc welding or manual arc welding, with low-hydrogen electrodes such as J507 preferred. The interpass temperature must be strictly controlled during welding, not less than or equal to 150 degrees Celsius, and the weld slag must be thoroughly cleaned to avoid contaminating the titanium cladding. Tungsten inert gas (TIG) welding is used for titanium materials, and the argon purity is [not specified]. With a purity of ≥99.99%, and in conjunction with a drag shield and back protection device, the weld and heat-affected zone are fully covered by inert gas below 200℃. When titanium is welded to steel, an intermediate transition layer, such as pure vanadium or vanadium-copper alloy, is required between them. Metallurgical bonding is achieved through explosive welding or rolling composite processes to avoid the formation of brittle intermetallic compounds from direct fusion. The tower body is made of titanium composite plate material, and the welding method used in the tower body solves the problems of high processing difficulty of titanium materials and complex welding and heat treatment processes in existing technologies, while improving the corrosion resistance and service life of the separation tower.
