Description
Technical field
The utility model is related to a kind of freezing dust pelletizing system, more particularly, on a kind of refining furnace applied to smelting industry
Freezing dust pelletizing system.
Background technology
At present, for the requirement of environmental protection, need to carry out purified treatment to waste gas in smelting industry, conventional processing mode is
It will be uniformly processed using axial flow blower after waste gas centralized collection；But, find, inhaled using axial flow blower in actual use
Wind mode, not only noise is big, high energy consumption, and effect of being put together to discarded collection is not good, causes partial fume to dissociate outer workshop,
Operating personnel and environment are adversely affected；In addition, EGT is higher, and it is miscellaneous containing a large amount of dust in hot humid waste gas
Matter, easily causes the blocking of rear end filter plant, influences filtration, purification effect.
The content of the invention
The purpose of this utility model is to overcome that above-mentioned not enough there is provided a kind of gas collection effect is good, the smelting of detergent power by force
Industry vacuum refrigeration dust pelletizing system.
What the purpose of this utility model was realized in：
A kind of smelting industry vacuum refrigeration dust pelletizing system, the system includes multiple collection being installed on above refining furnace
Gas hood, the gas skirt is communicated to discharge, and the discharge is communicated to the import of spiral dust catcher through stainless steel telescopic joint,
It is set with the outer tube wall of the discharge in cooling jacket, the cooling jacket and has been passed through cooling medium, the spiral dedusting
It is set with the shell wall of device in water jacket, and water jacket and has been passed through cooling water, temperature is installed at the import of the spiral dust catcher
Sensor, the outlet of the spiral dust catcher is connected to the import of sack cleaner, and the outlet of the sack cleaner is extremely
Vacuum pump set；At the import of the sack cleaner and exit is mounted on B/P EGR Back Pressure Transducer EGR.
Nitrogen is installed on a kind of the utility model smelting industry vacuum refrigeration dust pelletizing system, the sack cleaner clear
Apparatus for ash, the nitrogen deashing device, which includes, is communicated with many branch pipes on the gas main being connected with source nitrogen, the gas main,
The branch pipe is communicated to sack cleaner.
A kind of the utility model smelting industry vacuum refrigeration dust pelletizing system, a debugging pipe is connected to discharge, the tune
The top of test tube is connected to steam jet pump by a Pneumatic baffle valve.
Compared with prior art, the beneficial effects of the utility model are：
The utility model causes whole channel interior to be in negative pressure state using vacuum pump set, so that flue gas can be
When entering pipeline under the suction-operated of negative pressure, whole process is noiseless safely, and having multiple refining furnaces without phase conventional system that
Sample installs multiple blower fans, and negative-pressure air-suction can be carried out as usual by needing pipeline connection badly, not only reduces equipment cost, and cause whole
Installation process is more simple, while additionally aiding the Late reformation extension of factory building；In addition, by being cooled down to discharge, making
Obtain the liquefaction of the gaseous impurities in flue gas to filter out, leave the flue gas of cool drying, not only serve the effect of precooling and rough dusting,
And the flue gas after cool drying is not only easy to follow-up cleaner to carry out dedusting operation, and dry flue gas does not result in dedusting and set
Standby blocking and corrosion, the flue gas after cooling also will not be because of high temperature failure cleaner, so as to help making for extension whole system
Use the life-span.
