Description

Technical Field

[0001] This invention relates to the field of organic waste gas treatment, and specifically to a multi-stage adsorption oil and gas recovery device. Background Technology

[0002] During the production, storage, transportation, and handling of organic chemicals, organic components volatilize into the atmosphere. Once in the atmosphere, these components participate in atmospheric chemical reactions, contributing to smog. Typical applications include: oil loading and unloading at docks, by trucks and trains; and storage of intermediate and finished oil products in tank farms. Typical components include: crude oil, gasoline, diesel, jet fuel, benzene, toluene, and xylene (BTX), and other volatile components. The organic waste gases generated in these typical environments are characterized by high concentrations and large fluctuations. For these highly variable waste gases, the mainstream approach currently employs oil and gas recovery processes, such as adsorption + absorption, condensation + adsorption, and membrane + adsorption processes. These processes have made significant contributions to reducing VOC emissions in past practices. Chinese patent discloses a multi-stage adsorption oil and gas recovery device (authorization announcement number CN209885536U). This patent technology discloses a multi-stage adsorption oil and gas recovery device in which oil and gas sequentially pass through an absorption module, a primary adsorption module, and a secondary adsorption module to achieve VOCs recovery and compliance with emission standards. The absorption module cools the absorbent to reduce its volatility. The primary and secondary adsorption modules achieve compliant emissions of the exhaust gas through porous media adsorption. The multi-stage adsorption module periodically regenerates the adsorption media through a vacuum desorption module. The technology used in this device can improve the design of existing adsorption and absorption technologies to meet the latest emission standards. This patented technology solves the problem that, with the increasing national emission standards, existing technologies are gradually becoming incompatible with the latest emission standards in practice, placing significant environmental pressure on end users.

[0003] However, in existing technologies, different types of oil and gas have different water content, which can easily lead to poor filtration effects of activated carbon filters.

[0059] According to the above embodiments, the working principle of this invention is as follows:

[0060] Oil and gas that require multi-stage adsorption filtration for recovery are sequentially discharged into multiple multi-stage filtration structures 2 through the oil and gas inlet pipe 4 connected to the oil and gas adsorption tower 1, and undergo targeted multi-stage adsorption treatment according to the type of oil and gas.

[0061] Oil and gas are discharged through the second treatment pipe 208 into the corresponding single oil and gas filter structure 22 in the multi-stage oil and gas treatment structure 21, where the oil and gas are adsorbed and filtered.

[0062] When adjusting the specifications of oil and gas, the adjusting cylinder 203 separates the connecting pipe 205 and the processing pipe 207 from the oil and gas filter structure 22 in the multi-stage oil and gas processing structure 21.

[0063] After starting the servo motor 2107, the servo motor 2107 will drive the worm 2106, causing the worm 2106 to mesh with the worm wheel 2105 and rotate. The rotating worm wheel 2105 can drive the assembly shaft 2101 to rotate along the inner side of the assembly shaft frame 201, so that the angle position of the oil and gas filter screen 2202 of activated carbon, silica gel or activated alumina can be adjusted.

[0064] It is beneficial to use filter screens for targeted multi-stage adsorption treatment of oil and gas;

[0065] When cleaning the oil and gas filter screen 2202, water can be supplied through the connected cleaning water pipe to fill the oil and gas filter screen 2202 corresponding to the two connecting pipes 205. After the oil and gas filter screen 2202 is filled with water, the bidirectional motor 2114 is started. After the bidirectional motor 2114 is started, it drives the drive rod 2113 to rotate. The rotating drive rod 2113 drives the gear one 2112 to mesh with the gear two 2206. The gear two 2206 drives the stirring blade 2205 inside the inner ring shaft 2203 to rotate continuously on both sides of the oil and gas filter screen 2202, which is beneficial to improve the cleaning efficiency when rinsing the adsorbed material.
