Description
Technical field
Patent of the present invention provides a kind of technology that is applied to be in leak stopping in the relatively static fluid means, belongs to the leakage stopping technology field, and specifically a kind of gas pressure pipeline is discharged condensate water device and using method.
Background technique
Water seal for coal gas is to make the height of water in gas pressure and the water seal reach pressure balance by certain water level, the sealing of getting rid of the condensed water in the coal gas or keeping gas collecting tube by liquid-discharging tube.The effect of gas pipe line water seal is the water of getting rid of in the pipeline, and the degree of depth (static pressure of formation) that requires liquid-discharging tube to insert in the water must be greater than the pressure of gas in pipelines.The valve that liquid-discharging tube enters between water seal fits badly because applying working condition very easily damages, and exists to leak hidden danger, causes water seal for coal gas can't realize changing.Present technique is by utilizing liquid-solid transforming principle, the medium that possesses conversion performance under the simple condition is introduced the water seal for coal gas liquid-discharging tube by liquid state from the outside, the leak stopping medium is condensed into rapidly solid-state in then will managing by external refrigeration after entering in the pipe, afterwards realize the purpose of pipeline closed, reach the effect of leak stopping.
Summary of the invention
The present invention aims to provide a kind of technology that does not need complicated leakage-baffling device can realize leak stopping.Technological scheme of the present invention is realized by following method:
A kind of gas pressure pipeline is discharged condensate water device, comprise the gas main road, on described gas main road, draw an arm downwards, insert in the flashback tank lower end of described arm, and the degree of depth (static pressure of formation) in the arm insertion water is greater than the pressure of gas in pipelines, and in described arm bottom the first valve is installed, it is characterized in that, the A point of arm one side between described the first valve and gas main road is installed a filling apparatus, described filling apparatus comprises filler pipe, the second valve and leak stopping medium container, described filler pipe middle part has a sagging U-shaped section, and leak stopping medium container and the second valve lay respectively at the outside and the inboard of U-shaped section, and described leak stopping medium container and the arm A height difference of ordering is greater than the pressure of gas in pipelines.
Further, be coated with the steam tracing composite pipe in the outside of filler pipe.
The leak stopping medium that holds in the described leak stopping medium container is: the coking naphthalene.
The method of changing the first valve is as follows:
At first close the second valve (4); The steam tracing composite pipe passes into heating steam in (81); The leak stopping medium is filled in the leak stopping medium container (5), can the outside leak stopping medium that uses in the steam heating leak stopping medium container (5), guarantee that the leak stopping medium melts smoothly then to enter filler pipe for liquid; Slowly open the second valve (4), the leak stopping medium enters arm; With the cooling water outside arm (3) is cooled off rapidly, the leak stopping medium of guaranteeing to enter arm (3) is converted into solid-state by liquid state, stop up afterwards arm (3) and the first valve (2);
Then, after leak stopping is closely knit, close the second valve, i.e. replaceable the first valve (2);
The first valve (2) is changed complete, can pass through the contrary operation of external heat arm and the first valve, is liquid with remaining leak stopping medium melting in it, discharges by the first valve (2) to get final product.
The invention has the beneficial effects as follows:
The present invention utilizes liquid-solid transforming principle, becomes rapidly after in the device that the leak stopping medium introduce to need is stopped up by liquid state by the external heat thermal insulation apparatus solid-state to realize leak stopping.Can realize replacing and the maintenance of flashback tank.
The leak stopping medium is that solid originally is the large shortcoming in routine use, the conveying by the liquid solidification and crystallization easily under simple condition, the present invention breaks the normal procedure just, utilize this shortcoming to realize the purpose of leak stopping, it is a kind of good measure of reverse thinking, and after leak stopping is finished, still can by solid-state be converted into liquid to realize the elimination of leak stopping, simple to operate.This technology is very suitable for inflammable and explosive dangerous industry and the occasion that can not get angry.
