Abstract
The utility model discloses an online repair circulating device of a non-melting blast furnace cooling wall. The online repair circulating device is composed of a circulating pump, a heat exchanger and a connecting pipe, wherein the heat exchanger is a tube type heat exchanger and composed of a plurality of heat exchange plates; a heat exchange water inlet is formed at the bottom of the heat exchanger, while a heat exchange water outlet is formed at the top of the heat exchanger; a healant inlet is formed at the upper part of the heat exchanger, while a healant outlet is formed at the lower part of the heat exchanger; a compressed air connection is further arranged at the upper part of the heat exchanger; the circulating pump is mounted at the healant outlet through a connecting pipe; the connecting pipe connects the inlet and the outlet of the cooling water pipeline of non-melting damage of the cooling wall with the healant inlet and the healant outlet, respectively, thereby forming a circulating system. The device has the advantages that (1) the blast furnace cooling wall is repaired on line, so that normal production is not influenced; (2) the repairing cost is low and the operation is simple; and (3) the repaired cooling wall has good heat-conducting property, the original structure can not be damaged, and a plurality of times of repairing can be carried out, so that the repaired cooling can have the normal service life. The device is applied to pig-iron smelting enterprises.
Description
Technical field
The utility model relates to pig iron smelting equipment, in particular to the online device of repairing of blast furnace cooling stave.
Background technology
Blast furnace is the main equipment of pig iron smelting technique, and cooling stave then is blast furnace structure important component part.The working condition of cooling stave is one of significant effects factor of blast furnace campaign, is also having a strong impact on Main Economic technical indicator and safety that blast furnace is produced simultaneously.Because the crude fuel condition, the reasons such as operating duty, the blast furnace cooling stave non-melting loss of beginning or abradability about blow-on a year and a half are damaged, and the method for processing at present this damage type has: 1. the injection process of cutting off the water supply; 2. diminishing method of curing; 3. poling method of reproduction; 4. replacing method.For example Chinese patent application part CN1372008 number " method for preparing water cooling pipe for cooling wall of blast furnace ", CN1818077 number " pipeline leakage checking and blocking technology on iron-blast furnace cooling wall ", CN101550462 number " a kind of method for preparing water cooling system of blast furnace cooling wall ", CN102534078A number " a kind of replacement method for cooling water pipe of cooling wall of blast furnace " etc.All there are some shortcomings in these methods, or can not tackle the problem at its root, or are exactly to change by damping down, lose huge.There is no at present blast furnace cooling stave and repair online the application part of circulation device.
Summary of the invention
The purpose of this utility model provides non-melting loss blast furnace cooling stave and repairs online circulation device, to realize the online repairing of the non-melting loss damage of iron-smelting blast furnace cooling stave, prolongs blast furnace campaign.
The non-melting loss blast furnace cooling stave that the designer provides is repaired circulation device online, is comprised of recycle pump, interchanger, pipe connecting; Interchanger is shell and tube heat exchanger, is comprised of some heat exchanger fins, and its bottom has heat-exchanging water import, top that the heat-exchanging water outlet is arranged, and heat-exchanging water is process in pipe; The healant import is arranged at interchanger top, and the healant outlet is arranged at the bottom, and healant is process between pipe, carries out heat exchange with heat-exchanging water; Interchanger top also has compressed-air actuated interface, is used for repairing the pipeline pressurization; Recycle pump is installed in the outside that healant exports by pipe connecting, and pipe connecting is used for respectively the cooling water pipeline of the non-melting loss damage of cooling stave being imported and exported with the healant import and export being connected, and forms lesser circulation.
The pipeline that above-mentioned heat-exchanging water import, heat-exchanging water outlet, healant import connect all has valve, is used for switch and the flow of control heat-exchanging water and healant.
The inlet and outlet of above-mentioned recycle liquid pump and compressed-air actuated interface all are equipped with by-pass valve control.
Above-mentioned interchanger also is equipped with liquidometer, tensimeter and wash water valve.
Non-melting loss blast furnace cooling stave is repaired the circulation device using method online: pipe connecting is used for respectively the cooling water pipeline of the non-melting loss damage of cooling stave being imported and exported with the healant import and export being connected, and forms lesser circulation; Then the dirt layer that adds clean-out system cleaning water-cooled tube adds clear water displacement clean-out system, again healant is sent into lesser circulation, is delivered to the cooling stave damaged location, constantly circulates final repair damaged position; At last the water-cooled tube of repairing is suppressed, is hunted leak with pressurized air, reach normal cooling wall operating requirement after, repair and finish.
Non-melting loss blast furnace cooling stave of the present utility model is repaired online the circulation device advantage and is: 1. repair online blast furnace cooling stave, do not affect blast furnace and normally produce; 2. it is low to repair cost, simple to operate; 3. the cooling stave good heat conductivity after repairing is not destroyed original structure, and can repeatedly be repaired, and makes it really reach normal service life.Be applicable to pig iron smelting enterprise.
