Abstract

The utility model relates to the professional fuel gas field, in particular to a drainage device of condensate disposed at the bottom of the gas pipeline. The buoyancy gas draining equipment comprises an elbow (1), an outer cylinder (2), a buoy (3) and a discharge pipe (4). One end of the elbow (1) is connected with the gas pipeline and the other with the outer cylinder (2); the buoy (3) is positioned inside the outer cylinder (2); one end of the discharge pipe (4) is positioned in the lower part of the buoy (3) and the other end is connected with the atmosphere. The condensate in the gas pipeline first enters into the elbow, then into the lower part of the buoy; when the water level in the buoy reaches buoy floating level, the buoy will leave the discharge pipe, float and begin to discharge water. When the water level of the elbow decreases and the buoy contacts with the drainage pipe base, the drainer will close and stop discharging. The utility model has simple structure and low cost, and is convenient to maintain, safe and reliable, thereby avoiding the occurrence of breakdown and gas leakage. The utility model is suitable to being applied under different working stress and has a wide application.

Description

The buoyancy type coal gas drainer

Affiliated technical field:

The utility model relates to the combustion gas professional domain, relates in particular to the drainage means of the condensed fluid that deposits to the pipe end in the gas pipe line.

Background technique:

Combustion gas is meant metallurgical coal gas, manufactured gas, manufactured fuel gas, rock gas etc., is one of current main energy sources kind.The metallurgical coal gas bag is drawn together blast furnace gas, coke-stove gas, coal gas of converter etc., all belongs to the abundant coal gas resource of iron and steel enterprise, and these coal gas are the industrial fuels of high-quality after purifying recovery.These coal gas are in passing through pipe conveying procedure, because the reduction of gas temperature, the mechanical water in the coal gas, liquid impurity and saturation water constantly separate, condensation is got off.These condensed waters will in time discharge, otherwise ponding is too much, will blocking pipe, strengthen the resistance that coal gas is carried, and hinder the normal conveying of gas.The discharging of condensed water is discharged by coal gas drainer.The present coal gas drainer that generally adopts is the water-sealed type hydathode, is inserted into the tank with certain water seal height draw the waste pipe that gets off from pipeline, and coal gas is sealed, and in the advanced screw clamp of pipeline water of condensation, then flowing full is discharged from tank.There is following shortcoming in this hydathode: when (1) surpasses its water seal height when gas pressure, may cause water seal to puncture, coal gas is overflowed, have an accident, even cause serious casualties loss.(2) generally only be suitable for following low middle gas pipe line, the narrow application range of pressing of 50Kpa.And to some this type of hydathodes that has elevated pressures to require, the volume heaviness, or adopt the hydathode of electronic control, cost is very high.(3) bulky, the cost height.(4) operation management inconvenience will keep water, the water level of running check hydathode for a long time.When stopping state takes place when, inconvenient maintenance.

The model utility content:

The utility model purpose provides a kind of buoyancy type coal gas drainer, utilizes floating drum to lean on the variation automatic lifting of water level, realizes continuous drainage, solves the problems referred to above that exist in the background technique.

The technical solution of the utility model is: the buoyancy type coal gas drainer comprises bend pipe, urceolus, floating drum in forming, diffuses waste pipe, one end of bend pipe is communicated with gas pipe line, the other end is communicated with urceolus, floating drum places in the urceolus, an end that diffuses waste pipe places the below of floating drum, and the other end is communicated with atmosphere.

Be provided with inner core in the urceolus, floating drum places in the inner core, and inner core mainly has been the guiding of floating drum and spacing effect, and the shape of floating drum can be arbitrarily.

Bend pipe is provided with drain pipe, is used to discharge the impurity that is deposited in the bend pipe bottom.

For guaranteeing the isostasy in bend pipe and the urceolus.Bypass tube one end is communicated with bend pipe, and the other end is communicated with the upside of urceolus.

One end of discharge pipe places the below of floating drum, the other end with diffuse waste pipe and be communicated with, be three-way shape, diffuse the waste pipe both ends open, the coal gas that the upper end discharging is leaked, lower end draining.

The water of condensation of gas pipe line enters bend pipe earlier, and some impurity of water of condensation are deposited to the bend pipe bottom, can get rid of by drain pipe.Water of condensation behind bend pipe enters urceolus, and urceolus has the effect of stable water level inside and fixing internal assembly, reduces water level fluctuations.Float water level when the water level of urceolus reaches, floating drum leaves the draining base and floats, the beginning draining.When the drawdown of bend pipe, floating drum,, is equivalent to hydathode and closes during tube end contact draining base when floating drum descends along with synchronous decline, stops draining.If the water of condensation of pipeline is continuous, so, floating drum is in dynamic float state, continuous drainage automatically.

The utlity model has simple in structure, little investment, characteristics easy to maintenance, can not take place to puncture and the gas leakage situation, safe and reliable, and applicable to different working pressures, Applicable scope is big.

Description of drawings:

Fig. 1 is the utility model structural representation.

Among the figure: bend pipe 1, urceolus 2, floating drum 3, discharge pipe 4, inner core 5, drain pipe 6, bypass tube 7, diffuse waste pipe 8.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.

In an embodiment, an end of bend pipe 1 is communicated with the gas pipe line of making somebody a mere figurehead, and the other end is communicated with the downside of urceolus 2, be provided with inner core 5 in the urceolus 2, floating drum 3 places in the inner core 5, and floating drum 3 is spherical, one end of discharge pipe 4 places the below of floating drum 3, the other end with diffuse waste pipe 8 and be communicated with, be three-way shape, diffuse waste pipe 8 both ends opens, the coal gas that the upper end discharging is leaked, the lower end draining, bend pipe 1 is provided with drain pipe 6, is used to discharge the impurity that is deposited in bend pipe 1 bottom.Bypass tube 7 one ends are communicated with bend pipe 1, and the other end is communicated with the upside of urceolus 2.The water of condensation of gas pipe line enters bend pipe 1 earlier, and some impurity of water of condensation are deposited to bend pipe 1 bottom, avoids impurity to be brought into urceolus 2, stops up waste pipe, and the impurity that is deposited in bend pipe 1 bottom can be got rid of by drain pipe 6.Water of condensation behind bend pipe 1 enters urceolus 2, and urceolus 2 has the effect of stable water level inside and fixing internal assembly, reduces water level fluctuations.Inner core 5 mainly has been the guiding of floating drum 3 and spacing effect.Floating drum 3 lower seal adopt the reliable sealing material, and sealing is tight.Float water level when the water level of urceolus 2 reaches, floating drum 3 leaves the draining base and floats, the beginning draining.Water is discharged into sewerage by the lower end of diffusing waste pipe 8.If gas leakage is arranged, the coal gas of Guo Louing will be arranged to atmosphere by the upper end of diffusing waste pipe 8 so.When the drawdown of bend pipe 1, floating drum 3 under the acting in conjunction of floating drum 3 gravity own and gas pressure, is sealed the draining base along with synchronous decline tightly at the bottom of the floating drum, be equivalent to hydathode and close, and stops draining, simultaneously also can leakage gas.If the water of condensation of pipeline is continuous, so, floating drum 3 is in dynamic float state, continuous drainage automatically.
