Detailed Description
Embodiments of the present utility model will be described in detail with reference to fig. 1 to 2.
Referring to fig. 1-2, the submerged arc furnace high temperature fume collecting, separating and encrypting system comprises: the device comprises an ore furnace 1, a smoke dust collecting device 2, a smoke dust cooling device 3 and a separation encryption system 4; the devices are sequentially connected in series for collecting and separating high-temperature smoke dust of the submerged arc furnace;
the separate encryption system includes: a cylindrical cyclone bin 40 extending tangentially into an air inlet passage 41 of the cyclone bin 40, and an air outlet pipe 42 extending vertically upward from the cyclone bin 40; a cone 43 installed at the lower portion of the cyclone bin 40 for dropping dust, and a storage bin 44 installed at the lower portion of the cone 43 for collecting dust.
Further, the air inlet channel 41 is arranged along the inner wall of the cyclone bin 40 in a fan shape after being led into the cyclone bin 40. The gas in the cyclone bin can spiral downwards along the inner wall of the separation encryption system, so that dust falls into the storage bin along the inner wall.
Further, the sectional area of the spiral air inlet on the air inlet channel 41 positioned outside the cyclone bin 40 is larger than the sectional area of the cyclone air outlet on the air inlet channel positioned inside the cyclone bin 40, so that the air flow entering the cyclone bin 40 through the air inlet channel 41 is accelerated to a flow speed of 15-25 m/s.
Further, a filter screen 420 is disposed at the end of the exhaust pipe 42 to separate the secondary smoke and dust, so as to prevent the falling large-particle dust from being mixed into the purified gas under the cyclone effect.
Further, a straightener 421 for adjusting the flow rate of the purge gas is disposed below the filter screen 420.
Further, a vortex finder 422 for detecting the flow rate of the purge gas in the exhaust pipe 42 is provided below the straightener 421.
Further, a deflection cone 440 for dredging dust is installed at the dust outlet of the cone 43 and the inlet of the storage bin 44.
Further, the separation encryption system 4 is connected with 3-4 stages in series, the size of each stage is different, and dust with different particle sizes is collected and separated.
Further, the mesh of the filter 420 on each stage becomes smaller. The more the number of separation times, the smaller the dust particles, the higher the separation difficulty, and the smaller the filter screen mesh.
Working principle: the smoke dust generated in the submerged arc furnace 1 is collected into the smoke dust collecting device 2 through a pipeline, when the smoke dust collected in the smoke dust collecting device 2 reaches the maximum capacity, the smoke dust enters the smoke dust cooling device 3 through the pipeline, and the smoke dust with qualified cooling is introduced into the separation encryption system 4 through an induced draft fan. The airflow containing the smoke dust enters from the spiral air inlet of the tangential air inlet channel 41, is accelerated to 15-25 m/s along the spiral air inlet channel 41 and flows out from the cyclone air outlet, and the rotating motion of the airflow is caused in the process, so that solid particles with larger inertial centrifugal force are thrown to the inner wall surface of the cyclone bin 40 to be separated, fall onto the inner wall of the cone 43 along the inner wall and fall into the storage bin 44 along the inner wall shape of the cone 43, and the accumulated dust is dredged into the storage bin 44 by the deflection cone 440 at the feed inlet of the storage bin 44, so that the feed inlet of the storage bin 44 is kept smooth. Meanwhile, the air flow containing smaller particles gradually rises from the middle part of the cyclone bin 40 to enter the exhaust pipe 42, the vortex detector 422 in the exhaust pipe 42 detects the flow rate of the purified gas, and the straightener 421 above the vortex detector 422 adjusts the flow rate of the purified gas so as to quickly flow out of the exhaust pipe to enter the next separation encryption system for separation. The filter screen 420 at the end of the exhaust pipe 42 secondarily filters large-particle dust mixed into the purified gas by the cyclone. After the preliminary smoke dust separation is finished, the purified gas containing fine particle dust in the exhaust pipe enters the next separation encryption system 4 through the exhaust pipe to be separated, and the steps are repeated until the smoke dust separation is qualified.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the technical solutions according to the embodiments of the present utility model.
