Abstract
The invention provides liquid discharging equipment for a pump-line. A liquid discharging pipe (2) is connected to the lowest position of the pump-line (1), and the lower end of the liquid discharging pipe (2) extends into water (4) in a water storage well (3) so as to be plugged by the water (4) to realize automatic discharge of liquid in the pump-line. The liquid discharging equipment is simple to manufacture, is used for discharging liquid in the pump-line, preventing the liquid from plugging the pump-line and smoothly pumping out gas in a silicon carbide smelting furnace, and has the advantages of simplicity and convenience in operation, low cost as well as safety and reliability.
Description
Technical field
The invention belongs to the silit technical field of smelting, relate to the automatic eliminating facility of the interior liquid of pump-line when gas is drawn out of outside the stove in a kind of sic smelting furnace.
Background technology
Sic smelting furnace is made up of headwall, side wall, siege.Existing silit production technology can't be extracted the gas safety in the smelting furnace out, with the purpose that realizes holding concurrently collection and confinement of gases negative pressure smelts.Make a large amount of CO gases after the smelting furnace surface combustion, form CO on the one hand
2Directly enter atmosphere, not only wasted resource but also increased the quantity discharged of carbon, can't realize the production requirement of energy-saving and emission-reduction, low-carbon environment-friendly, can't realize that on the other hand negative pressure smelts and reduce the product power consumption.
Summary of the invention
After this crucial difficult problem of sealing in the smelting furnace stove between subenvironment and stove outer air solved, the problem that safe withdrawing gas need solve in the stove was exactly the design of air-bleed system, and the eliminating of liquid is one of problem that will solve in the air-bleed system pipeline.
Contain a large amount of water in the smelting furnace furnace charge, contain a large amount of fugitive constituents simultaneously, be vaporizated into gas under their high temperature in stove and be drawn out of outside the stove, because temperature reduces, just be condensed into liquid and stay in the pipeline in the time of outside getting into pipeline arrival stove with CO.Because less relatively draft can not make the liquid in the pump-line be drawn out of with gas, along with increasing of liquid, pump-line just takes place stop up, the work of bleeding can not be realized smoothly.
The present invention provides a kind of pump-line to remove the liquid facility, realizes getting rid of automatically liquid in the pump-line, solves pump-line and stops up the purpose of extracting furnace gas smoothly out.
Technical scheme of the present invention is such: a kind of pump-line removes the liquid facility, comprises liquid discharge pipe, retaining well.Be filled with water in the retaining well, the liquid discharge pipe bottom is blocked up in water seal, makes pump-line not suck air.
Water level in the retaining well just adopts automatic control, and the ordinary water-level height is h2.When making water level be lower than the h2 certain value, start water replanishing device to retaining well automatic water supplement because of evaporation, seepage etc.; When because after the inflow of discharge opeing liquid in pipe etc. make water level be higher than the h2 certain value, start water-freeing arrangement the retaining WIH discharged automatically.
The present invention has following unusual effect:
1, the present invention is rational in infrastructure, makes simple, with low cost.
2, execute-in-place of the present invention is easy, removes liquid work realization and reliable automatically.

Embodiment
Embodiment of the present invention combines accompanying drawing explanation:
Embodiment one:
As shown in the figure, make pump-line (1) gradually low to the centre, so that the liquid in pipe gravity flow from two ends.Lowest part at pump-line (1) connects liquid discharge pipe (2), guarantees to connect air tight.Liquid discharge pipe (2) lower end is stretched in the water (4) in the retaining well (3), made liquid discharge pipe (2) lower end stifled by water seal.Set the height h1 that liquid discharge pipe (2) surfaces according to the draft size.The height that automatic control system maintenance water level h2 is set is in setting range.So far accomplish the automatic eliminating work of the interior liquid of pump-line (1).
More than, making when being negative pressure value in the pipe when beginning to bleed, the liquid level in the liquid discharge pipe (2) is higher than the interior liquid level of retaining well (3); Difference of altitude is looked the negative pressure degree and difference; But ultimate value is for being no more than 10 meters, and h1 gets 10 meters long or slightly long when therefore generally designing, and does not get weak point or more long value but do not limit.The span of h2 (liquid level) requires: on the one hand can not be little, guarantee that the length that liquid discharge pipe (2) stretches in the water will meet the demands, and promptly when sucking the liquid of setting height in the liquid discharge pipe (2), the height of h2 will guarantee to flood the lower end of liquid discharge pipe (2); On the other hand can not be big, guarantee to suck in the liquid discharge pipe (2) liquid level and be no more than set(ting)value, even liquid is not inhaled into pump-line (1).
Claims (1)
1. a pump-line removes the liquid facility, it is characterized in that the lowest part of pump-line (1) is connected with liquid discharge pipe (2), and liquid discharge pipe (2) lower end is stretched in the water (4) in the retaining well (3), and liquid discharge pipe (2) lower end is by water (4) shutoff.
