Description
Technical field
The utility model belongs to steelmaking equipment field, specifically a kind of cooling structure of Blast Furnace Bottom.
Background technology
The furnace bottom cooling of modern blast furnace is mostly water-cooled, and generally arranges drop-bottom.The cooling effect of furnace bottom water cooling tube is taken away by water coolant the heat that furnace bottom carbon brick absorbs from cupola well.After water coolant carries out heat exchange, general increasing extent of temperature is not very high, and absorb heat less, a large amount of low-temperature cooling water cannot reuse and directly drain, and causes the waste of low-temperature cooling water.
Utility model content
The utility model provides a kind of cooling structure of Blast Furnace Bottom, in order to solve defect of the prior art.
The utility model is achieved by the following technical programs:
The cooling structure of Blast Furnace Bottom, comprise brick layer and lower brick layer, between upper brick layer and lower brick layer, heat transfer zone is set, filler is filled in heat transfer zone, water pipe is installed in heat transfer zone, main heat exchange pipe and secondary heat transfer tube, water inlet pipe communicates with main heat exchange pipe, threeway is installed in the exit of main heat exchange pipe, one tunnel of threeway connects water outlet, one end of the other end auxiliary connection heat transfer tube of threeway, the other end of secondary heat transfer tube connects the feed-water end of main heat exchange pipe, secondary heat transfer tube and main heat exchange pipe arrange the check valve only allowing to be flowed to main heat exchange pipe by secondary heat transfer tube, secondary heat transfer tube arranges water pump close to the position of threeway, the exit end of main heat exchange pipe installs temperature measuring set.
The cooling structure of Blast Furnace Bottom as above, the periphery of described main heat exchange pipe arranges several heat exchanger fin, and each heat exchanger fin is made up of several fanning strip and several strengthening ring, and fanning strip is evenly distributed on the periphery of main heat exchange pipe, and each fanning strip connects by strengthening ring.
The utility model has the advantages that: the utility model can in main heat exchange pipe once used water coolant carry out temperature survey, when temperature of cooling water is still lower, second stage employ is carried out by nonrecoverable water coolant suction to secondary heat transfer tube by water pump, the utilization ratio of effective raising water coolant, saving water resource.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model; Fig. 2 be along Fig. 1 A-A line analyse and observe structure for amplifying schematic diagram.
Reference numeral: brick layer 10 filler 11 check valve 12 fanning strip 13 strengthening ring 14 heat transfer zone on 1 time secondary heat transfer tube 9 of brick layer 2 water inlet pipe 3 temperature measuring set 4 threeway 5 water pump 6 heat exchanger fin 7 main heat exchange pipe 8.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The cooling structure of Blast Furnace Bottom, as shown in Figure 1, comprise brick layer 9 and lower brick layer 1, between upper brick layer 9 and lower brick layer 1, heat transfer zone 14 is set, filler 10 is filled in heat transfer zone 14, water pipe 2 is installed in heat transfer zone 14, main heat exchange pipe 7 and secondary heat transfer tube 8, water inlet pipe 2 communicates with main heat exchange pipe 7, threeway 4 is installed in the exit of main heat exchange pipe 7, one tunnel of threeway 4 connects water outlet, one end of the other end auxiliary connection heat transfer tube 8 of threeway 4, the other end of secondary heat transfer tube 8 connects the feed-water end of main heat exchange pipe 7, secondary heat transfer tube 8 and main heat exchange pipe 7 arrange the check valve 11 only allowing to be flowed to main heat exchange pipe 7 by secondary heat transfer tube 8, secondary heat transfer tube 8 arranges water pump 5 close to the position of threeway 4, the exit end of main heat exchange pipe 7 installs temperature measuring set 3.The utility model can in main heat exchange pipe once used water coolant carry out temperature survey, when temperature of cooling water is still lower, carry out second stage employ by water pump by nonrecoverable water coolant suction to secondary heat transfer tube, effectively improve the utilization ratio of water coolant, saving water resource.
Specifically, as shown in Figure 2, the periphery of the main heat exchange pipe 7 described in the present embodiment arranges several heat exchanger fin 6, and each heat exchanger fin 6 is made up of several fanning strip 12 and several strengthening ring 13, fanning strip 12 is evenly distributed on the periphery of main heat exchange pipe 7, and each fanning strip 12 connects by strengthening ring 13.This structure can increase heat interchanging area, improves heat transfer effect.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
