Abstract
The utility model provides a kind of top combustion stove settling chamber blow device, comprise nitrogen pipeline and stack gases pipeline, set up waste gas small transfer line at stack gases pipe end, the waste gas small transfer line the other end connects nitrogen pipeline, waste gas small transfer line is connected with induced draft fan and exhaust gas control valve.The utility model has reasonable in design, easy to install, the advantages such as effect is good.Owing to setting up waste gas small transfer line at stack gases pipeline, by induced draft fan, stack gases is introduced settling chamber replacement nitrogen and settling chamber and coal gas duct are purged, thus production cost can be reduced greatly.
Description
Technical field
The utility model belongs to hotblast stove cleaning mechanical means, particularly a kind of top combustion stove settling chamber blow device.
Background technology
Card Shandong goldentop burning type hot-air furnace is the another kind of type of regenerative hot blast stove, and its core is settling chamber.Settling chamber is divided into coal gas and the large room of combustion air two, and all there is the multiple vent channel of two rows each room.Air and Gas Flow formation spirrillum during burning, reach coal gas and combustion air fully mixes, the object of perfect combustion.There are two kinds of situations: one is that hotblast stove has remaining coal gas and is trapped in coal gas duct and settling chamber top when wind is passed in burning, meets high temperature easily blast with air mixed in production practice.Two is hotblast stove air-supplies when turning burning, has residual air to be trapped in coal gas duct and settling chamber top, mixes meet high temperature and also easily blast with coal gas.The consequence of blast is that hotblast stove settling chamber is badly damaged, causes normally producing.In order to address these problems, after Combustion of Hot Air Furnace, settling chamber is purged, to get rid of hidden peril of explosion.Existing hotblast stove blow device is made up of parts such as gas line, air line, nitrogen pipelines.With nitrogen, settling chamber and coal gas duct are purged, to eliminate coal gas after each burning.With nitrogen, settling chamber and coal gas duct are purged, to eliminate air after air-supply terminates.The object of hotblast stove conversion nitrogen purging at every turn replaces coal gas wherein and air, thus destroy the condition of gas explosion, avoids hotblast stove settling chamber to damage.But because nitrogen is expensive, cause purging cost too high, millions of unit need be consumed every year.
Summary of the invention
The utility model transforms existing hotblast stove blow device, by setting up the way of exhaust pipeline in a device, the waste gas produced during Combustion of Hot Air Furnace being introduced settling chamber replaces nitrogen to purge settling chamber and coal gas duct, thus reach saving nitrogen, reduce the object of production cost.
For this reason, the technical solution of the utility model is:
A kind of top combustion stove settling chamber blow device, comprise nitrogen pipeline and stack gases pipeline, it is characterized in that, set up waste gas small transfer line at stack gases pipe end, the waste gas small transfer line the other end connects nitrogen pipeline, waste gas small transfer line is connected with induced draft fan and exhaust gas control valve.
The utility model has reasonable in design, easy to install, the advantages such as effect is good.Owing to setting up waste gas small transfer line at stack gases pipeline, by induced draft fan, stack gases is introduced settling chamber replacement nitrogen and settling chamber and coal gas duct are purged, greatly reduce production cost.Be 100mm by existing purging hotblast stove settling chamber and coal gas duct nitrogen pipeline diameter, each hotblast stove conversion purging 10 seconds, every day calculates for 48 times, each saving nitrogen 637 cubic metres, nitrogen 30576 cubic metres can be saved every day, by nitrogen every cubic metre 0.2 yuan calculating, can save more than 220 ten thousand yuan every year, economic benefit is considerable.
Accompanying drawing explanation
Fig. 1 is top combustion stove settling chamber blow device structural representation.
In figure: gas line 1, air line 2, nitrogen pipeline 3, nitrogen gas control valve 4, stack gases pipeline 5, chimney 6, settling chamber 7, waste gas small transfer line 8, induced draft fan 9, exhaust gas control valve 10.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail:
As shown in Figure 1, settling chamber 7 is provided with in top combustion stove furnace roof, hotblast stove is connected to gas line 1, air line 2, nitrogen pipeline 3, stack gases pipeline 5, chimney 6 and hot-blast outlet 7, the utility model is at waste gas of hot-blast stove flue pipeline 5 distal aperture, connection diameter 400mm waste gas small transfer line 8, the other end of waste gas small transfer line 8 connects nitrogen pipeline 3, on waste gas small transfer line 8, set up induced draft fan 9 and exhaust gas control valve 10 simultaneously, by induced draft fan 9, stack gases is introduced in nitrogen pipeline 3, replace nitrogen and complete the work of settling chamber purging.
During normal production, close the nitrogen gas control valve 4 on nitrogen pipeline 3, open the exhaust gas control valve 10 on newly-increased waste gas small transfer line 8, by induced draft fan 9, the waste gas in stack gases pipeline 5 is blown in settling chamber and coal gas duct, purges remaining coal gas and air.Original nitrogen pipeline 3 and nitrogen gas control valve 4 retain, and break down once induced draft fan 9, can use nitrogen instead and purge.
