Abstract
The invention discloses a leak detector for a blast furnace cooler. The leak detector comprises an air collecting tank which is a transparent vessel, wherein a water inlet pipe and a valve are arranged below the air collecting tank; an air outlet pipe and a valve are arranged on the upper part of the air collecting tank; a water outlet pipe is arranged inside the air collecting tank; a water outlet at the top of the water outlet pipe is higher than the air outlet of the air outlet pipe; the bottom end of the water outlet pipe is located at the bottom of the air collecting tank. By virtue of the leak detector, leak detection can be performed while a blast furnace is in normal production; with neither disconnecting of water nor damping down, but only through control on a small amount of water, whether gas exists in a pipeline can be visibly known by viewing whether air bubbles float up in the transparent air collecting tank, so that leak points can be rapidly and correctly detected, the detection time is shortened and the labor intensity of detecting workers is reduced.
Description
Technical field
The present invention relates to the instrument that a kind of test set leaks, be applicable to adopt the leak detection of the cooling water cooler of closed loop sofe water, particularly a kind of blast furnace cooler leak locator.
Background technology
Blast furnace is that transverse section is circular ironmaking shaft furnace.With steel plate, make furnace shell, in shell, build fireproof brick inner lining.Between the furnace shell of furnace bosh, bosh, cupola well part and liner, water cooler is set, forms a circle to protect furnace lining.Blast furnace cooler has internal layer and the independent water channel of outer two-way, internal layer and outer independent water-in, the water outlet of being provided with.From cupola well, start upwards, three to four water coolers are one group, see Fig. 1.Fig. 1 is the schematic diagram that one group of water cooler internal layer or outer simply connected are used state.Between every group of water cooler, internal layer or outer field water inlet pipe and rising pipe are connected in series from beginning to end, are finally connected with outfall sewer with water inlet manifold, form internal layer and outer two independent cooling systems.The cooling blast furnace cooler of closed loop sofe water, once find that certain blast furnace cooler internal layer or skin leak, close the water intaking valve on this road water inlet pipe, untie water inlet pipe and the rising pipe of this water leakage of cooler pipeline, be connected with outfall sewer with water inlet manifold separately, open little water management, when overhaul, change.When water cooler big area is damaged, promptly broken stove skin is changed.Skip at ordinary times this water cooler that leaks, with pipe fitting, other water cooler in this group is linked together and continues to use.Leaking of blast furnace cooler, if can not find timely and process, the normal production that threatens blast furnace that will be serious, greatly reduces blast furnace production economy index and converter life, even can cause the serious accidents such as hearth freeze-up.Judging from the current situation, blast furnace leak hunting technology is substantially still in manual observation aspect, when furnace temperature, water temperature or coal gas abnormal, water tender turns down water intaking valve, whether now the interior gas pressure of stove is greater than the pressure of water, opens one by one the vent valve on water cooler, observe in water and obviously have gas to discharge, occur this situation, leaking of water cooler caused serious impact on the production of blast furnace.Due to the deficiency of the aspects such as leak hunting technology, leak detection experience and equipment, find a unconspicuous leakage point of initial stage and will use the longer time, can not check leakage point even at all.Only have when water leakage of cooler is serious by the time and be just easily found, for leaking of water cooler initial stage, the detection method not had at present.
Summary of the invention
Technical problem to be solved by this invention is, under blast furnace normal production conditions, quick and precisely detects leak source, shortens detection time, alleviates labor strength.
For above-mentioned technical problem, the technical scheme that the present invention takes is, a kind of blast furnace cooler leak locator, comprise air collector, described air collector is transparent utensil, and its below is provided with water inlet pipe and valve, the top of air collector is provided with escape pipe and valve, rising pipe is housed in air collector, and the water outlet on rising pipe top is higher than the air outlet of escape pipe, and the bottom of rising pipe is positioned at the bottom of air collector.
One side of described air collector is provided with water level gauge.
With flexible pipe, water inlet pipe of the present invention is connected with the vapor pipe on water cooler, is full of water, can use.
Advantage of the present invention is, realized the leakage detection when blast furnace is normally produced, and do not cut off the water supply, and whether damping down, only needs a small amount of control water, just can have bubble floating, liquid level to decline by observing transparent air collector, intuitively learns in pipeline, whether there is coal gas.Thereby fast, accurately leak source detected, shortened detection time, alleviated detection labor strength.
Accompanying drawing explanation
Fig. 1 is that the cooling system of one group of water cooler internal layer of existing blast furnace or outer simply connected uses view.
Fig. 2 is the structural representation of leak detection view of the present invention.
In figure: 1. air collector, 2. water inlet pipe, 3. rising pipe, 4. escape pipe, 5. valve, 6. water level gauge.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, referring to Fig. 2, a kind of blast furnace cooler leak locator, comprise air collector 1, air collector 1 is transparent utensil, and its below is provided with water inlet pipe 2 and valve 5, the top of air collector 1 is provided with escape pipe 4 and valve 5, rising pipe 3 is housed in air collector 1, and the water outlet on rising pipe 3 tops is higher than the air outlet of escape pipe 4, and the bottom of rising pipe 3 is positioned at the bottom of air collector 1.
One side of described air collector 1 is provided with water level gauge 6.
In conjunction with Fig. 1, when blast furnace is normally produced, on the vapor pipe of each water cooler, with hose connection water inlet pipe 2 of the present invention, rising pipe 3 keeps long logical state.Open the valve on vapor pipe, the air in air collector 1 is got rid of in water inlet, when the air outlet of escape pipe 4 has water to discharge, represents the interior air emptying of air collector 1, is full of water, closes valve and the valve on escape pipe 5 on vapor pipe, comes into operation.Make regular check on, within general 2～4 hours, observe once.During observation, turn down the valve on water cooler water inlet pipe, open the valve on vapor pipe, if blast furnace cooler is damaged, can collect coal gas in stove, the air collector 1 of making from transparent utensil, be clear that bubble floating, or the water level gauge 6 of installing from a side of air collector 1 sees that liquid level declines, the speed declining according to bubble dense degree and size and liquid level, can judge leak whether serious.Thereby fast, leak source accurately detected; If do not see bubble floating the air collector 1 of making from transparent utensil, and not decline of liquid level, represent that this water cooler is without leakage, intact.
The present invention uses transparent utensil to collect the coal gas spilling from water cooler, and steam water interface carbonated drink is automatically separated, causes liquid level in leak locator to decline and visual, intuitively demonstration.
