Abstract
The present invention relates to a jointed soft water sealing and circular cooling system for cooling a blast furnace. Soft water passes through cooling devices containing a furnace bottom cooling pipe 1, a serpentine pipe 2, a direct-cooling pipe 3, a small sleeve 5, a medium sleeve 6, a direct-blowing pipe 7, a hot-air valve 8 and the like and are collected after the cooling devices are combined by all or partial pipelines in a serial connection mode and a parallel connection mode, the soft water enters a gas eliminating tank 9 through the pipelines for gas elimination and then enters an expansion tank 10 for pressurization and leakage detection, and finally, the soft water is cooled through a heat exchanger 11 and then is newly sent to a blast furnace by a main pump 12. The jointed soft water sealing and circular cooling system has the advantages of little total consumption of the cooling water, small pipeline diameter, less quantity of the pipelines, the pumps, the heat exchanger, valves, the gas eliminating tank and the like and less total investment and operating cost.
Description
(1), technical field
The present invention relates to a kind of blast furnace refrigerative joint soft water sealing and circular cooling system that is used for.
(2), background technology
Blast furnace cooling system mainly contains evaporated cooling system, service water cooling system, soft water airtight circulating cooling system now, a blast furnace the inside, these three kinds of cooling systems can use separately, also can the service water cooling system and soft water airtight circulating cooling system be used in combination.Soft water airtight circulating cooling system has following major advantage: water quality is good, the cooling duct non-scaling, pollution-free, cooling intensity is high, good cooling results, leakage less, overbottom pressure can utilize fully, level of automation is high and advantage such as reliable.Soft water airtight circulating cooling system reduces about 18～21% than the service water cooling system every year on working cost.Thereby soft water airtight circulating cooling system application at home and abroad more and more widely.At present, blast furnace adopts full soft water airtight circulating cooling system, and three independently soft water closed circulation systems need be arranged, that is: body of heater soft water closed circulation system, furnace bottom soft water closed circulation system, air port and hot blast valve soft water closed circulation system.The cooling system soft water Total Water of Shi Yonging is more like this, and pipeline, valve, cooling apparatus are more, and correspondingly gross investment and working cost are also higher.
(3), summary of the invention
The joint soft water sealing and circular cooling system that the purpose of this invention is to provide the shared cover circulation cooling apparatus of a kind of body of heater, furnace bottom, air port and hot blast valve, many to solve in the existing soft water cooling system water loss, pipeline, valve and cooling apparatus are many, the problem that gross investment and working cost are high.
Realize that technical solution of the present invention is: a kind of joint soft water sealing and circular cooling system, mainly form by cooling apparatus, degassing vessel, expansion drum, interchanger, main pump, soft water converges after adopting all or part of pipeline series connection and mode in parallel to make up by cooling apparatuss such as furnace bottom cooling tube, serpentine tube, direct-cooled pipe, little cover, middle cover, belly pipe, hot blast valves, enter the degassing vessel degassing by pipeline, enter expansion drum pressurization, leak detection then, last soft water is delivered to blast furnace by main pump again through the interchanger cooling.
The present invention is combined in the cooling of equipment such as body of heater, furnace bottom, tuyere small sleeve, middle cover, belly pipe, hot blast valve in the soft water closed circulation system by series connection and parallel connection.The patent global cycle water yield of the present invention be three independently soft water closed circulation system Total Water about 50%, after adopting joint soft water sealing and circular cooling system, number of tubes reduces, pipe diameter reduces, the number of devices such as quantity minimizings, the minimizing of heat exchanger quantity, valve and degassing vessel of pump reduce and the minimizing of corresponding construction investment, gross investment than three independently the soft water closed circulation system reduce about 14%; Every year of the present invention on working cost than three independently the soft water closed circulation system reduce about 18%.
(4), description of drawings
Fig. 1 is a kind of system flowchart of joint soft water sealing and circular cooling system.
Fig. 2 is the another kind of system flowchart of joint soft water sealing and circular cooling system.
(5), embodiment
The present invention is described further below in conjunction with accompanying drawing.
In Fig. 1: furnace bottom cooling tube 1 back of connecting with body of heater serpentine tube 2 is in parallel with the direct-cooled pipe of body of heater 3, after two-way cooling soft water converges, be divided into two-way, one the tunnel directly receives degassing vessel 9 fronts, another road is supplied with tuyere small sleeve 5, middle cover 6, belly pipe 7 and hot blast valve 8 in parallel respectively after pressurizeing through topping-up pump 4, enters degassing vessel 9 degassings after converging with last road thereafter, enters expansion drum 10 pressurizations then, hunts leak, last soft water is delivered to blast furnace by main pump 12 again through interchanger 11 coolings.Topping-up pump 4 is used for the pressure between equalizing main, can also guarantee soft flow in each cooling apparatus simultaneously.
In Fig. 2: furnace bottom cooling tube 1 back of connecting with body of heater serpentine tube 2 is in parallel with the direct-cooled pipe of body of heater 3, after two-way cooling soft water converges, enter degassing vessel 9 degassings, enter expansion drum 10 pressurizations, leak detection then, last soft water is delivered to blast furnace by main pump 12 again through interchanger 11 coolings.At this moment, the cooling of tuyere small sleeve 5, middle cover 6, belly pipe 7 and hot blast valve 8 can be adopted the service water circulating cooling system in addition separately.
This joint soft water sealing and circular cooling system also can adopt the better pure water of water quality except that adopting the soft water.
