Description

Technical Field

[0001] The utility model relates to the field of petrochemical production, in particular to a device for removing hydrogen sulfide from refinery dry gas. Background Art

[0002] In recent years, the sulfur content of crude oil processed by my country's refineries has been increasing. Refinery dry gas mainly contains hydrogen sulfide. The amount of hydrogen sulfide in refinery dry gas mainly depends on the sulfur content of the processed crude oil and the processing conditions adopted. The more sulfur content in the crude oil and the deeper the processing depth, the greater the hydrogen sulfide content in the refinery dry gas.

[0003] At present, refineries mainly use packed towers or plate towers to remove hydrogen sulfide from dry gas. This not only reduces equipment corrosion during the refinery dry gas processing process, but is also beneficial to environmental protection and the chemical utilization of gas products. However, when using packed towers or plate towers to remove hydrogen sulfide, blockage will generally occur after a period of operation, thus affecting the long-term production of the device.

[0004] For example, the "hydrogen sulfide absorption device" disclosed in the Chinese patent literature has a publication number of CN210057880U, which includes a reactor, which is used to hold alkali solution, an absorption tower is arranged on the top of the reactor, and a packing layer is arranged inside the absorption tower; a hydrogen sulfide delivery pipeline is passed from the top of the reactor into the reactor, and an exhaust port is arranged on the top of the absorption tower; a spray pipeline is connected to the bottom of the reactor, and the other end of the spray pipeline is connected to the top of the absorption tower, and a liquid pump is arranged on the spray pipeline. The disadvantage of this patent is that desulfurization through the packing layer will be blocked after a period of time, and the packing needs to be replaced, which affects the production process. Utility Model Content

[0005] The utility model aims to overcome the problem in the prior art that the packing layer of the device will be blocked after a period of desulfurization, which affects the production process.

In other words, the desulfurization reactants will not remain in the tower, so similar blockages will not occur during long-term use, and it will be more stable in the long-term production process.

[0009] Preferably, the rotary spray assembly comprises an amine liquid rotary spray inlet pipe and a rotary spray pipe, wherein a spiral flow channel is provided in the rotary spray pipe. After the dry gas enters the spiral flow channel, it rotates, thereby colliding with the amine liquid entering radially, and the amine liquid is collided into a plurality of mist droplets, which continuously move in the rotary spray pipe, further increasing the contact with the dry gas.
