Abstract
The utility model discloses a device for discharging condensate water in a gas pressure pipeline. The device comprises a gas main pipeline, wherein a branch pipe is led from the gas main pipeline downwards; the lower end of the branch pipe is inserted into a water seal tank; and the lower part of the branch pipe is provided with a first valve. The device for discharging the condensate water in the gas pressure pipeline is characterized in that a filling device is arranged at a point A at one side of the branch pipe between the first valve and the gas main pipeline; the filling device comprises a filling pipe, a second valve and a plugging medium container; the middle part of the filling pipe is provided with a drooping U-shaped part; the plugging medium container and the second valve are respectively positioned outside and inside the U-shaped part; and the height difference of the plugging medium container and the point A of the branch pipe is higher than the pressure of the gas in the pipeline. With the adoption of the device for discharging the condensate water in the gas pressure pipeline, a liquid solid transformation principle is utilized, a plugging medium is led into the device needed to be plugged from a liquid state by an external heating heat-preservation device, and the plugging medium is rapidly changed into a solid state to realize plugging, so that the change and the maintenance of the water seal tank can be realized.
Description
Technical field
The utility model patent provides a kind of technology that is applied to be in leak stopping in relatively static fluid means, belongs to the leakage stopping technology field, and specifically a kind of gas pressure pipeline is discharged condensate water device.
Background technique
Water seal for coal gas is to make the height of water in gas pressure and water seal reach pressure balance by certain water level, the sealing of getting rid of the condensed water in 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 pipeline, and the degree of depth (static pressure of formation) that requires liquid-discharging tube to insert in 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 simple condition is introduced the water seal for coal gas liquid-discharging tube from the outside by liquid state, in managing by external refrigeration after entering in pipe, the leak stopping medium is condensed into rapidly solid-state, afterwards realize the purpose of pipeline closed, reach the effect of leak stopping.
The model utility content
The utility model aims to provide a kind of technology that does not need complicated leakage-baffling device can realize leak stopping.The technical solution of the utility model is realized by following method:
a kind of gas pressure pipeline is discharged condensate water device, comprise the gas main road, draw an arm downwards on described gas main road, insert in flashback tank the lower end of described arm, and the degree of depth (static pressure of formation) in 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 the height difference of described leak stopping medium container and arm joint (A point) 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 described leak stopping medium container is: the coking naphthalene.
The beneficial effects of the utility model are:
The utility model 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 easily that solid is originally the large shortcoming in routine use, conveying by the liquid solidification and crystallization under simple condition, the present utility model is broken 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 completed, 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.
Description of drawings
Fig. 1 is the original structure schematic diagram;
Fig. 2 is that the utility model utilizes liquid-solid transforming principle to realize the leakage stopping technology schematic flow diagram;
In figure: 1 gas main road, 2 first valves, 3 arms, 4 second valves, 5 leak stopping medium container, 7 gas main roads, 8 filler pipes, 81 steam tracing composite pipes.
Embodiment
As shown in Figure 1 and Figure 2,
Some low-melting medium (leak stopping medium) under simple condition by cooling be easily solid by the liquid solidification and crystallization, be liquid in the situation that heating is melted by solid, this is the principle place of this device.
A kind of gas pressure pipeline is discharged condensate water device, comprise gas main road 7, in general, gas main road 7 horizontal arrangement, draw an arm 3 downwards on the gas main road, insert in flashback tank 1 lower end of arm, and arm inserts the degree of depth (static pressure of formation) in water greater than the pressure of gas in pipelines, in the arm bottom, the first valve 2 is installed.
The A point of arm one side between the first valve 2 and gas main road 1 is installed a filling apparatus, filling apparatus comprises filler pipe 8, the second valve 4 and leak stopping medium container 5, filler pipe 8 is abnormity, formed by three parts, comprise inboard horizontal pipe, the U-shaped section at middle part and the vertical tube in the outside, the sagging U-shaped section at middle part once advances, be coated with steam tracing composite pipe 81 in the outside of filler pipe, the steam tracing composite pipe is also corresponding is divided into three sections.And leak stopping medium container 5 and the second valve 4 lay respectively at outside vertical tube and the inboard horizontal pipe place of U-shaped section, and leak stopping medium container 5 and the arm A height difference of ordering is greater than the pressure of gas in pipelines.
The leak stopping medium that holds in described leak stopping medium container is:.
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); Leak stopping medium (coking naphthalene) is filled in leak stopping medium container (5), can the outside leak stopping medium that uses in 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 carried out rapidly coolingly, 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.
