Blockage removing device for wet desulphurization process

Abstract

The invention discloses a blockage removing device for a wet desulphurization process. The blockage removing device comprises a distributor and a gas source system, wherein the distributor comprises a central pipe and a plurality of branch pipes, the central pipe is used for supplying air to the branch pipes, one end of each branch pipe is communicated with the central pipe, the other ends of the branch pipes are radially arranged in a star shape around the central axis of the central pipe, each branch pipe is provided with a nozzle, the nozzle faces downwards, an included angle between the nozzle and the central axis of the central pipe is an acute angle, and the gas outlet of the gas source system is communicated with the central pipe and used for intermittently providing compressed gas for the distributor. According to the invention, a fluid intermittently impacts sulfur blocks on the wall surface of a container while a desulfurization liquid rotates to form stirring and scouring, so that sulfur can be well prevented from caking on the wall surface of the container, the caked sulfur can be well impacted and crushed, and can be prevented from being agglomerated into large blocks, the good capacity of cleaning the sulfur on the wall surface of the container is achieved, shutdown caused by blockage of the container due to settlement is avoided, and long-period operation of the device is facilitated.

Description

Technical field[0001]The present invention relates to the field of crane attachments, in particular, a wet desulfurization process is interpolated.Background technique[0002]With a large number of oil fields in the oil field, there is often a single sulfur precipitation, blockage the tower and pipeline during operation of the wet desulfurization device, and currently reduce the amount of settlement by optimizing the desulfurization agent parameters, and can effectively reduce the plugging frequency. In addition, the optimization pipe size, increase dredging equipment, etc., it is also possible to treat sulfur blockage in the pipeline, but the desulfurization liquid flows slowly in containers such as tower, tank, and kettle, and sulfur particles are very contained in the head. Cake and ultimately lead to blockage, once clogging requires a shutdown and maintenance, for example, the demolished and clogged container enters its internal cleaning, so that the workload is large and not cond...

Problems solved by technology

[0002] With the large-scale exploitation of high-sulfur gas fields in oilfields, elemental sulfur often precipitates during the operation of existing wet desulfurization devices, clogging towers and pipelines. At present, optimizing desulfurizer parameters to reduce the amount of sedimentation can effectively reduce the frequency of clogging. In addition, optimizing the size of the pipeline and adding dredging equipment can also better deal with the problem of sulfur blockage in the pipeline. However, the flow rate of desulfurization liquid in towers, tanks, kettles and other containers is slow, and sulfur particles are very likely to settle on the head of the container. Agglomeration and eventually lead to clogging, once clogged, it needs to be shut down for maintenance, for example, the clogged container needs to be disassembled and washed to enter its interior for cleaning, so the workload is heavy and it is not conducive to the long-term operation of the device
