Abstract
An online recovering device for water seal of a blast furnace airtight box consists of an airtight box, an airtight box cooling water inlet pipeline, a valve, an airtight box water drainage ring pipe joint, a water drainage pipeline, a water return pipeline control valve, a water replenishing pipeline, a water replenishing pipeline control door, a tee joint and a water seal pipeline. A water inlet on the upper portion of the airtight box is connected with the valve, the valve is fittingly connected with the airtight box cooling water inlet pipeline, the airtight box water drainage ring pipe joint is disposed on the lower portion of the airtight box and is fittingly connected with one end of the water drainage pipeline, the other end of the water drainage pipeline is connected with one end of the water replenishing pipeline control door, the other end of the water replenishing pipeline control door is fittingly connected with the tee joint, the two other ends of the tee joint are fittingly connected with the water seal pipeline and the water replenishing pipeline, and a control valve is arranged between the water replenishing pipeline and the tee joint. Production cost is increased as water seal can be recovered by an original device only on the condition of wind reduction, but the online recovering device can recover the water seal without water reduction.
Description
Affiliated technical field:
The utility model relates to blast furnace airtight box anti-leak field.Especially raw gas gas water seal arrangement in the blast furnace airtight box.
Background technology:
Domestic no bell furnace roof all adopts airtight box and distributor chute cloth, and the cooling gas sealing system of airtight box has two kinds of devices, a kind of employing closed cycle water cooling, nitrogen-sealed; The another kind of employing opened wide water cooling, utilizes raw gas in the water seal arrangement sealing State of Blast Furnace.Adopt and open wide water cooling, the shortcoming of the device of water seal arrangement sealing blast furnace raw gas is, water seal arrangement must recover its water seal when causing water seal to occur destroying owing to the syphonic effect of water or other reason under the situation of blast furnace checking, have influence on the ordinary production of blast furnace and, security incident occurs as can not in time repairing even cause peripheral personnel that carbon monoxide poisoning takes place.
Summary of the invention:
Must recover the deficiency of its water seal in order to overcome when water seal arrangement causes water seal to occur destroying owing to the syphonic effect of water or other reason under the situation of blast furnace checking, the utility model provides the water seal of a kind of blast furnace airtight box online recovery device.Water seal occurs and puncture under the situation of checking not and recover water seal, do not influence production.
For solving the problems of the technologies described above, technical solution adopted in the utility model is by airtight box, airtight box cooling water inlet pipe road, valve, airtight box draining endless tube contact, discharge pipe line, the water return pipeline by-pass valve control, water pipe, moisturizing pipeline control gate, threeway, the water seal pipeline constitutes, airtight box top water-in is connected with valve, valve and airtight box cooling water inlet pipe road are connected, airtight box draining endless tube contact is arranged at the airtight box bottom, contact and discharge pipe line one end are connected, discharge pipe line end in addition is connected with moisturizing pipeline control gate one end, moisturizing pipeline control gate end in addition is connected with threeway, threeway in addition two ends and water seal pipeline and water pipe is connected, and between water pipe and threeway contact by-pass valve control is arranged.
The beneficial effects of the utility model are: original device must recover the airtight box water seal under the situation of checking, increased production cost, and this device not checking can recover the airtight box water seal.
Description of drawings:
Fig. 1 is the utility model structural front view.
Embodiment:
The utility model is by airtight box 4, airtight box cooling water inlet pipe road 6, water inlet control valve door 5, airtight box draining endless tube contact 7, discharge pipe line 8, water return pipeline by-pass valve control 3, water pipe 1, moisturizing pipeline control gate 2, threeway 9, water seal pipeline 10 constitutes, airtight box 4 top water-ins are connected with valve 5, valve 5 is connected with airtight box 4 cooling water inlet pipe roads 6, airtight box draining endless tube contact 7 is arranged at airtight box 4 bottoms, contact and discharge pipe line 8 one ends are connected, discharge pipe line 8 end in addition is connected with moisturizing pipeline control gate 3 one ends, moisturizing pipeline control gate 2 end in addition is connected with threeway 9, threeway 9 two ends and water seal pipeline 10 and water pipe 1 in addition is connected, and between water pipe 1 and threeway contact by-pass valve control 2 is arranged.During use, puncture, close airtight box 4 water inlet control valve doors 5 when the airtight box water seal occurring, close moisturizing pipeline control gate 3, open by-pass valve control 2, treat that water seal recovers after, close supplementary feed pipeline by-pass valve control 2, open airtight box 4 draining control valve doors 3, open airtight box 4 water inlet control valve doors 5.
