Abstract
The invention discloses a dust removal system for a refining furnace. The system comprises an exhaust pipe connected with an exhaust port of the refining furnace, wherein an exhaust chimney is connected to the exhaust pipe; a cooling water pipe is sleeved outside the exhaust pipe; one end of the cooling water pipe is connected with a cold water tank, and the other end of the cooling water pipe is connected with a water pump which is connected with the cold water tank; a dust remover is arranged at the end, close to the exhaust chimney, of the exhaust pipe. According to the system, vaporized exhaust gas in a gas guide pipe is re-cooled and cured through cold water, and is filtered by the dust remover, so that the probability of emission of the exhaust gas into the atmosphere is reduced, and air pollution is reduced.
Description
Technical field
The present invention relates to a kind of refining furnace dust pelletizing system.
Background technology
In field of metallurgy, when processing molten steel, metallurgical reaction all carries out in refining furnace, the various gases that produce in metallurgical reaction process are entered atmosphere by extract system from extracting out in refining furnace through hot-bending pipes, yet refining furnace itself, in order to obtain the more pure steel of high-quality, needs to carry out desulfurization and slag absorption work, remove harmful field trash, but be also that field trash is also likely vaporized and is then discharged in atmosphere, contaminated air.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, a kind of refining furnace dust pelletizing system is provided, reduce environmental pollution.
For achieving the above object, technical scheme of the present invention has been to provide a kind of refining furnace dust pelletizing system, comprise the blast pipe being connected with the exhaust port of refining furnace, described blast pipe is connected with exhaust chimney, described blast pipe is arranged with cooling water pipe outward, and one end of described cooling water pipe is connected with water cooling pond, and the other end of described cooling water pipe is connected with water pump, described water pump is connected with described water cooling pond, and described blast pipe is provided with deduster near described exhaust chimney end.
As preferably, in described cooling water pipe, be provided with the temperature sensor that detects cooling water temperature, described temperature sensor is connected with the electric controling switch of described water pump.
As preferably, on described deduster, be provided with ash-draining gate, described ash-draining gate and described deduster are hinged, and are provided with locking mechanism between the two.
As preferably, described blast pipe is also provided with near described exhaust chimney end the desulfurizer that lime is housed.
Advantage of the present invention and beneficial effect are: by cold water, the waste gas being vaporized in wireway is lowered the temperature again curing, then crossed deduster again and filter out, can reduce the probability that enters atmosphere, reduce the pollution of air.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Wherein: 1, refining furnace; 2, exhaust port; 3, blast pipe; 4, exhaust chimney; 5, cooling water pipe; 6, water cooling pond; 7, water pump; 8, deduster.

As shown in Figure 1, in described cooling water pipe 5, be provided with the temperature sensor that detects cooling water temperature, described temperature sensor is connected with the electric controling switch of described water pump 7, when the water temperature in temperature sensor detects cooling water pipe 5 raises, automatically electric controling switch is opened, water pump 7 is interior by cold water suction cooling water pipe 5 from water cooling pond 6, the water that originally temperature in cooling water pipe 5 is higher circulate enter in water cooling pond 6, carry out cooling, recycle saving water resource.
As shown in Figure 1, on described deduster 8, be provided with ash-draining gate, described ash-draining gate and described deduster 8 are hinged, and are provided with locking mechanism between the two.
As shown in Figure 1, described blast pipe 3 is also provided with near described exhaust chimney 4 ends the desulfurizer that lime is housed.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
