Description
Technical field
The present invention relates to waste gas emission treatment technical field, particularly relate to a kind of reduction furnace smoke extractor.
Background technology
Steel belt type reducing furnace is one of key equipment during metal dust produces, current domestic most popular band oven typically uses electricity, coal gas, oil heating, traditional band oven heating means are burner in the heating furnace both sides cross arrangement of band oven, the corresponding combustor of each burner, flame burns below Muffle, roof of the furnace has multiple exhaust smoke hole, make combustion product gases multiple exhaust smoke holes discharge from top, the corresponding smoke collecting mouth of each exhaust smoke hole, there is many defects in this smoke extractor: on the one hand, combustion product gases is the discharge of multiple steam vents from top, in causing burner hearth, upper and lower temperature difference is big, affect reduced iron powder quality；Thermal source can not make full use of, and causes energy waste；On the other hand, the flue gas of stove chamber inner combustion is directly or indirectly discharged in air, major polluting atmosphere environment, thus destroys ecological resources.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one and significantly improve energy utilization rate, reduce the burner hearth temperature difference, substantially reduce the steel belt type reducing furnace smoke extractor of discharge.
The present invention is achieved through the following technical solutions technical goal.
Steel belt type reducing furnace smoke extractor, is arranged on steel belt type reducing furnace heating furnace top；Including flue, smoke collecting device, smoke exhaust pipe, smoke exhaust fan；Described flue is arranged on burner and the stove tail two ends of heating furnace, is arranged over smoke collecting device at flue；Described smoke collecting device lower end horn mouth is corresponding with the outlet flue of flue, and upper end connects from side and connects smoke exhaust pipe；Described smoke exhaust pipe one end is closed, and the other end connects the air inlet of smoke exhaust fan；It thes improvement is that: described steel belt type reducing furnace smoke extractor is additionally provided with tail gas clean-up case；Described tail gas clean-up case includes casing, spray system, cleaning system, exhausting duct；The lower end of described casing is connected to the air outlet of smoke exhaust fan by pipeline；Described cleaning system is upper and lower multiple structure, fixes and be connected in being arranged on casing and with casing；Described spray system is arranged on the side of casing, including spray head, spray piping, water pump；Described spray head is arranged in the middle of the cleaning system of multiple structure；Described spray piping one end connects spray head, and the other end is fixedly attached to box bottom inner chamber；Described water pump is arranged in spray piping；Described exhausting duct is arranged on casing top.
In said structure, described pipeline between smoke exhaust fan and tail gas clean-up case is provided with cleaner unit.
The present invention compared with prior art, has the positive effect that:
1. the present invention only arranges flue outlet at burner and the stove tail of heating furnace, extend the flue gas holdup time in stove, make full use of fume afterheat, greatly reduce upper and lower temperature difference in heating furnace, effectively ensure that the temperature in heating furnace is not scattered and disappeared, thermal source is enable to make full use of, it is ensured that and improve reduced iron powder quality.
2. the present invention arranges exhaust gas purification equipment at the air outlet of smoke exhaust fan, and the flue gas of discharge is carried out reclaiming clean process, after spray system and cleaning system double purified process, it is achieved that the zero-emission of harmful gas in reduction furnace flue gas, protects large natural environment.
3. the pipeline between smoke exhaust fan and tail gas clean-up case is provided with cleaner unit, enters exhaust gas purification equipment after first the solid sundries in flue gas being filtered, make gas cleaning more thorough.
Purification efficiency the most of the present invention is high, energy consumption is low, range is wide, operate and easy to maintenance succinctly, work place will not be had any impact.
