Problems solved by technology

Although this environmental protection device also has the effect of recovering solvent and protecting the environment, this environmental protection device still has the following disadvantages: 1. The adsorption tower is a conventional adsorption tower, and the adsorption material has a short life, high running resistance, difficult renewal and recovery, and poor stability; 2. Lack of a detector to detect the solvent concentration, it is difficult to control the solvent concentration of the exhaust gas; 3. Lack of feeding pipelines, the adsorption material in the adsorption tower cannot be added in time, and it is difficult to realize continuous recovery of solvent oil; 4. No Cool the adsorption tower with inert gas

Embodiment 1

[0038] like figure 2 As shown, an adsorption tower for recovery of solvent oil mainly includes a cylinder, a cylindrical sleeve 12, a porous baffle, a metal filter screen and a solid adsorption material 13, wherein the cylindrical sleeve 12 is arranged inside the cylinder, and the same The number of cylindrical sleeves 12 in the cylinder is three, and the radius range is 0.5m-1.0m. A porous baffle is placed horizontally at the bottom port of the cylinder. The aperture of the porous baffle is 10 meshes, and its peripheral edge is fixed on the inner wall of the cylinder to support the cylindrical sleeve 12 inside the cylinder. In addition, the porous baffle is covered with There is a metal filter screen, and the aperture range of the metal filter screen is 100-150 mesh. Solid adsorption material is filled between the cylindrical sleeves, specifically spherical granular resin, with a specific surface area of ​​500m 2 / g. The cylinder is covered with an arc-shaped cover, which...

Embodiment 2

[0053] This embodiment also provides a kind of adsorption tower that is used for solvent oil recovery, mainly comprises cylinder, cylinder sleeve 12, porous baffle plate, metal filter screen and solid adsorption material 13, and this adsorption tower structure is the same as embodiment 1, The difference: the number of cylindrical sleeves 12 is 10, and the radius range is 0.5m-1.0m. The aperture of the porous baffle placed horizontally at the bottom port of the cylinder is 30 mesh, and the aperture of the metal filter screen above the porous baffle is in the range of 250-300 mesh. The specific surface area of ​​the spherical granular resin filled between the cylindrical sleeves is 1000m 2 / g. All the other are with embodiment 1.

Embodiment 3

[0055] The structure of the adsorption tower provided by the present embodiment and the solvent oil recovery system is the same as implementation 3, and the difference is that the processes of the adsorption tower A8 and the adsorption tower B9 are different, as follows:

[0056] see figure 1 , set the adsorption tower B9 to the adsorption mode. Using the induced draft fan 7, the solvent oil-containing waste gas discharged from the stripping kettle is sent to the adsorption tower B9, and the tail gas concentration detector 10 of the adsorption tower detects the concentration of the tail gas online. When the detected concentration exceeds the set value of 70mg / m 3 Finally, first open the inlet pipeline 6 valve of adsorption tower A8, then close the inlet pipeline 6 valve of adsorption tower B9. The adsorption tower B9 enters the desorption mode, and the adsorption tower A8 enters the adsorption mode. Open the valve 3 of the steam pipeline and the valve 5 of the oil outlet pi...

Abstract

The invention relates to an adsorption tower and system for recovering solvent oil. The adsorption tower mainly comprises a barrel, cylinder sleeves, a porous baffle plate, a metal filter screen and solid adsorption materials, wherein the cylinder sleeves are arranged in the barrel; the porous baffle plate is horizontally arranged at the end opening of the bottom of the barrel; the circumferential edge of the porous baffle plate is fixed on the inner wall of the barrel, and is used for supporting the cylinder sleeves in the barrel; the metal filter screen is laid on the porous baffle plate; each solid adsorption material is used to fill a space between two adjacent cylinder sleeves; and the adsorption tower is provided with a connector used for assembling a pipeline and / or auxiliary equipment. The invention also provides the solvent oil recovery system which comprises adsorption towers, a steam pipeline, an oil outlet pipeline, an air inlet pipeline, an exhaust pipeline, feeding pipelines, nitrogen pipelines, an induced draft fan, an adsorption tower tail gas concentration detector and an oil outlet pipeline concentration detector. Compared with the prior art, the adsorption tower and the system can realize the purposes of up-to-standard discharge of produced tail gas and reduction of the production cost.

Description

technical field [0001] The invention relates to a device for the treatment of tail gas discharged by chemical enterprises and the recovery and utilization of beneficial components, in particular to an adsorption tower and system for recovery of solvent oil Background technique [0002] Solvent oil is a petroleum product that has been cut and refined as a mixture of hydrocarbons, and is extremely flammable and explosive. In the current UHMWPE polymerization production process, a large amount of solvent oil is required, and because solvent oil is a volatile organic compound, the tail gas (exhaust gas) emitted during the UHMWPE polymerization production needs special treatment , such as installing a torch auxiliary combustion device to convert volatile organic compounds into carbon dioxide and water vapor through chemical reactions, and eliminate organic pollution to the atmosphere. [0003] In the current production process of industrial ultra-high molecular weight polyethyle...
