Abstract
The utility model proposes a kind of blast furnace roof bleeding devices of tranquility environmental protection, raw gas tedge including being set to furnace roof, stock gas diffusion valve and muffler are successively arranged along flue gas discharge direction on raw gas tedge, raw gas tedge includes general pipeline and several branch pipes, several branch pipes are connected with the perforation of the interval general pipeline, and stock gas diffusion valve and muffler are set on branch pipe.The utility model reduces the noise of stock gas release, and the feature of environmental protection is high.
Description
Technical field
The utility model belongs to the technical field of blast furnace gas diffusing more particularly to a kind of blast furnace roof of tranquility environmental protection is put
It is in bulk to set.
Background technique
Blast furnace gas is the byproduct in blast furnace ironmaking process.When blast furnace gas fluctuation or user are super using fluctuation
Out when adjustable range, to protect network security, necessarily lead to release.Currently, the release of blast furnace gas furnace roof does not generally set noise reduction facility,
Noise is big, not environmentally when release.
Summary of the invention
The technical problem to be solved by the utility model is in view of the above problems, provide a kind of tranquility environmental protection
Blast furnace roof bleeding device, blast furnace gas diffuse after passing through muffler, reduce release noise.
The utility model solves technical solution used by above-mentioned technical problem: a kind of blast furnace roof of tranquility environmental protection is put
It is in bulk to set, which is characterized in that the raw gas tedge including being set to furnace roof, along flue gas discharge direction on the raw gas tedge
It is successively arranged stock gas diffusion valve and muffler.
According to the above scheme, the raw gas tedge includes general pipeline and several branch pipes, several branch pipes and the interval general pipeline
Perforation is connected, and the stock gas diffusion valve and muffler are set on branch pipe.
According to the above scheme, the muffler be impedance complex formula muffler, sound-absorbing material be stainless steel punched hole noise absorption plate and
Blanket of glass wool.
According to the above scheme, the muffler is equipped with ash removing opening and manhole.
The beneficial effects of the utility model are: a kind of blast furnace roof bleeding device of tranquility environmental protection is provided, in blast furnace gas
Diffuse channel on muffler is installed, coal gas diffuses after passing through muffler, can substantially reduce noise when release, avoids noise dirty
Dye, it is more environmentally friendly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Wherein: 1- raw gas tedge；2- stock gas diffusion valve；3- muffler.
Specific embodiment
To more fully understand the utility model, the utility model work is further retouched with reference to the accompanying drawings and examples
It states.
As shown in Figure 1, a kind of blast furnace roof bleeding device of tranquility environmental protection, the raw gas tedge 1 including being set to furnace roof,
Stock gas diffusion valve 2 and muffler 3 are successively arranged along flue gas discharge direction on raw gas tedge.
Raw gas tedge includes general pipeline and several branch pipes, and several branch pipes are connected with the perforation of the interval general pipeline, and stock gas is put
It dissipates valve and muffler is set on branch pipe, the setting of multiple mufflers improves elimination efficiency.
Muffler is impedance complex formula muffler, and dispersing gas stream reaches noise reduction by the process of decompression, current stabilization and sound-absorbing
Effect, sound-absorbing material are stainless steel punched hole noise absorption plate and blanket of glass wool.
Muffler is equipped with ash removing opening and manhole, facilitates the regular deashing of staff and maintenance.
When stock gas in blast furnace staying or in emergency circumstances diffuses, the furnace roof at the top of blast furnace crude gas tedge is opened
Gas bleeding valve, subsequent blast furnace gas diffuse after passing through muffler noise reduction, reduce the noise of stock gas release, and the feature of environmental protection is good.
