Description

Technical Field

[0001] The utility model relates to the technical field of dry dust removal systems, in particular to a dispersing device and a dry dust removal system. Background Art

[0002] In the blast furnace gas dry dust removal system, the venting device is generally a vertical venting pipe installed on the gas pipeline, and the venting valve is usually installed on the vertical venting pipe. Once the slag enters the venting pipe of this venting device, the venting valve may be damaged. At this time, the whole venting pipe needs to be lifted up to replace the venting valve, which is very inconvenient. In addition, the venting pipe is generally extended to a high height, which increases the difficulty of replacement and maintenance.

[0003] Therefore, it is necessary to design a new scattering device and dry dust removal system to facilitate the maintenance of the scattering device. Utility Model Content

[0004] The utility model aims to provide a scattering device and a dry dust removal system to solve the problem of difficult maintenance of the existing scattering device and the dry dust removal system.

[0006] Optionally, the bottom of the vent pipe is sealed.

[0007] Optionally, the vent branch pipe also includes a vertical pipe section whose one end is connected to the gas pipeline, the other end of the vertical pipe section is connected to one end of the horizontal pipe section, and the other end of the horizontal pipe section is connected to the vent pipe.

[0008] Optionally, the relief device further includes a first manual valve, which is arranged on the relief branch pipe and located upstream of the relief valve.

[0009] Optionally, the first manual valve is arranged on the vertical pipeline.

[0010] Optionally, it further includes a safety pipe and a safety valve, one end of the safety pipe is connected to the gas pipe, the other end of the safety pipe is connected to the release pipe, and the safety valve is arranged on the safety pipe.

[0011] Optionally, the other end of the safety pipe is located downstream of the other end of the relief branch pipe.

[0012] Optionally, the relief device further includes a second manual valve, which is arranged on the safety pipe and located upstream of the safety valve.

[0013] Optionally, the bottom of the vent pipe is fixed on the gas pipeline.

[0014] The utility model also provides a dry dust removal system, comprising a gas pipeline and the above-mentioned scattering device, wherein one end of the scattering branch pipe is connected to the gas pipeline.

[0015] The utility model provides a dispersion device and a dry dust removal system, which have the following beneficial effects:

[0016] Since one end of the vent branch pipe is connected to the gas pipeline and the other end is connected to the vent pipe, the top of the vent pipe is connected to the atmosphere, and the vent pipe is connected to the gas pipeline through the vent branch pipe. Therefore, the gas in the gas pipeline can first pass through the vent branch pipe and then flow through the vent pipe, and then flow out from the top of the vent pipe. Since the vent branch pipe includes a horizontal pipeline section, the vent valve is arranged on the horizontal pipeline section. Therefore, it is possible to avoid the accumulation of residues in the vent pipe at the vent valve, which may cause damage to the vent valve, thereby extending the service life of the vent valve. At the same time, it is possible to avoid disassembling and hoisting the vent pipe when maintaining the vent valve. In this way, it is convenient to maintain the vent valve, and when maintaining the vent valve, it is only necessary to remove the vent valve from the horizontal section, which is further convenient for the maintenance of the vent valve and the cleaning of the residues accumulated in the vent pipe.
