In order to detect the leakage of blast furnace cooling device more accurately, preferably, said blast furnace cooling device leak detection apparatus also comprises conductivity meter, and said conductivity meter is connected with said control module circuit.In the specific embodiment of the utility model, said conductivity meter is the duct type conductivity meter.
In order to detect the leakage of blast furnace cooling device more accurately, in the specific embodiment of the utility model, said blast furnace cooling device leak detection apparatus also comprises pH meter, and said pH meter is connected with said control module circuit.
In order to detect the leakage of blast furnace cooling device more accurately, in order to detect the leakage of blast furnace cooling device more accurately, said blast furnace cooling device leak detection apparatus also comprises expansion drum, and said expansion drum is connected with said control module circuit.
In order to detect the leakage of blast furnace cooling device more accurately; In order to detect the leakage of blast furnace cooling device more accurately; Said blast furnace cooling device leak detection apparatus also comprises moisturizing assembly and flow measurement parts; Said moisturizing assembly pipeline connects said expansion drum, and said flow measurement parts are installed in the pipeline that connects between said moisturizing assembly and the said expansion drum and circuit connects said control module.
When the utility model is installed; Owing to there are high temperature furnace charges such as raw material, coal gas, molten iron, slag to exist in the blast furnace; Blast furnace is produced the later stage, and after refractory lining brick corroded and comes off, the cooling tube in the blast furnace cooling device can receive the wearing and tearing of decline furnace charge and rising coal gas and wash away and cause breakage.As shown in Figure 2, cooling device is in case damaged, is divided into A and two zones of B according to the furnace pressure and the cooling device hydraulic pressure of differing heights in the stove, wherein:
Gas pressure is higher than hydraulic pressure in the A district stove, and consequently blast furnace gas is sneaked in the recirculated water, this kind situation hunt leak main foundation: a, float switch action; B, cycle water worsen (coal gas is sneaked in the water in the stove, causes conductivity, pH value to change).Float switch is a kind of novel instrument, and it is installed in the gas that captures on the drainpipe in the pipeline, after the gas that traps is full of air chamber, drives float and sends contact point signal.
The float switch setting principle is: the place that cooling wall thermal load of living in is big, because the temperature difference is also big relatively, and therefore than cracky, in case damaged also big to the influence of blast furnace, so this is a main region of considering to be provided with float switch.Also have, the probability damaged apart from the near more cooling water pipe of furnace charge is big more, and it is also just many more that float switch is set; Want much little apart from furnace charge cooling water pipe probability of damage far away, therefore can be not if establish float switch less.The float switch overwhelming majority is concentrated and is arranged on the above bosh in air port, furnace bosh and shaft middle and lower part district's plush copper and the bight drainpipe.Can be at the blast furnace initial stage of putting into operation by the even distributed and arranged of cooled region of dividing.Later stage look working of a furnace truth and decide in the blast furnace running.
On the blast furnace platform, be provided with float switch leak detection field monitor dish; Be installed in each on-the-spot float switch and all on monitor, establish warning light; By corresponding one by one each the regional float switch of area arrangement, in case signal conveys to control module, the warning of control module control warning light.After operating personnel obtained reporting to the police, personnel were according to the warning light of observing on the monitor in notice on-site maintenance, in time cooling device repaired.
In addition, on draining collector stopple coupon, be provided with duct type conductivity and pH meter, keep watch on the cycle water situation of change.Because cooling device is in case appearance is damaged, coal gas is sneaked into and is caused change of water quality comparatively slow in the water, so this is only as the damaged supplementary means that detects.
B district furnace pressure is lower than hydraulic pressure, and consequently recirculated water is invaded in the stove, and difference in flow appears in the electromagnetic flowmeter that this kind situation hunts leak main foundation: a, be installed in the cooling device water inlet pipe and water outlet pipe; B, expansion drum decline of water table; C, rate of water make-up increase.
The water distribution principle of each blast furnace is not quite similar; Water distribution no matter in which way; On the plumbing arm of each cooled region, electromagnetic flowmeter should be set; And can consider the flowmeter that is provided with according to calculation of Heat Load simultaneously, when the difference in flow of reality surpassed setting value, control module control warning light sent damaged water leakage alarm.According to the zone that breakage occurs, rig-site utilization row pressure method is progressively confirmed the concrete position that leaks.Though electromagnetic flowmeter adopts the segmentation setting, it is very little that damaged water leakage is compared with the quantity of circulating water of the cooling device of flowing through, and requires difference flow measurement precision higher, so the principle of leak detection function is identical with the air port leak detection.Also have, in case occur leaking, descending appears in expansion drum water level at once, should in time search reason, and the external pipe that possibly occur cooling device leaks and carries out mending-leakage.In addition, in case occur leaking, descending appears in expansion drum water level at once, and the moisturizing assembly starts to expansion drum additional, and flow detection parts transmitted traffic signal is to control module, if flow signal continues, then possibly there is leakage in the blast furnace cooling device.
To sum up, the design of the blast furnace cooling device leak detection apparatus of the utility model is ingenious, simple for structure, easy and simple to handle, thereby reduces investment, reduces maintenance cost, is suitable for large-scale promotion application.
In this instructions, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and the scope of the utility model.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
