Description

Automatic drainage device of gas pipeline

The technical field is as follows:

the utility model relates to a gas pipeline drainage technical field especially relates to a gas pipeline's automatic drainage device.

Background art:

in the coal gasification production process, coal gas is conveyed through a coal gas pipeline, the coal gas contains saturated steam and other light oil, because the conveying pipeline is long, steam and oil gas can be greatly condensed in the conveying process to form an elbow and a low point, so that the coal gas pipeline forms a liquid seal to block the normal conveying of the coal gas, the coal gas pressure is indirectly too low, the coal gas pressure is low to cause the occurrence of a heat conduction oil boiler, a coal gas compressor and a tubular furnace trip accident, generally, manual regular drainage operation is carried out at the low point, once drainage is not timely, the liquid seal is extremely easy to cause, meanwhile, manual drainage is carried out, the possibility of coal gas poisoning accident occurrence exists, certain potential safety hazard exists, and urgent need to be improved.

The utility model has the following contents:

an object of the utility model is to provide an automatic drainage device of gas pipeline, solve the gas conveying pipeline among the prior art and take place liquid seal accident, artifical periodic drainage untimely easily, and have the technical problem of great potential safety hazard.

The contents of the utility model are as follows: the utility model provides a gas pipeline's automatic drainage device, its includes the drainage box the vertical baffle of installing in the drainage box, the baffle will water seal chamber and overflow chamber are cut apart into to the inner chamber of drainage box the overflow mouth has been seted up on the baffle vertical grafting in the water seal chamber has the drain pipe, the drain pipe extends to be connected with the gas pipeline outside the drainage box install flow valve and check valve on the gas pipeline water pumping port has been seted up on the drainage box, water pumping port with the overflow chamber is linked together.

Furthermore, a sealing cover is installed on the water pumping port.

Further, the sealing cover is made of transparent materials.

Furthermore, an emptying pipeline is arranged on the drainage box body.

Furthermore, a flame arrester is arranged on the emptying pipeline.

Furthermore, the distance between the bottom end of the drain pipe and the bottom end of the drain box body is 200 mm-400 mm.

The utility model has the advantages that: the utility model discloses simple structure establishes dedicated drainage water seal system for the gas pipeline, has both guaranteed gas pipeline pressure, has also realized automatic drainage, reduces workman work intensity of labour, has eliminated the potential safety hazard, has realized gas pipeline's profit recovery, has reduced the outer polluted environment that arranges of sewage, easy operation, convenience, cost reduction increases, is worth using widely.

Description of the drawings:

FIG. 1 is a schematic view of the present invention;

in the figure, a water seal chamber 1, an overflow chamber 2, a drain pipe 3, an overflow port 4, an emptying pipeline 5, a flame arrester 6, a gas pipeline 7, a water pumping port 8, a sealing cover 9 and a partition plate 10.

The specific implementation mode is as follows:

as shown in fig. 1, an automatic drainage device for a gas pipeline comprises a drainage tank body, wherein a partition plate 10 is vertically installed in the drainage tank body, the partition plate 10 divides an inner cavity of the drainage tank body into a water seal chamber 1 and an overflow chamber 2, an overflow port 4 is formed in the partition plate 10, a drainage pipe 3 is vertically inserted in the water seal chamber 1, the drainage pipe 3 extends out of the drainage tank body and is connected with a gas pipeline 7, a flow valve and a one-way valve are installed on the gas pipeline 7, a water pumping port 8 is formed in the drainage tank body, and the water pumping port 8 is communicated with the overflow chamber 2; a sealing cover 9 is arranged on the water pumping port 8; the sealing cover 9 is made of transparent materials; an emptying pipeline 5 is arranged on the drainage tank body; a flame arrester 6 is arranged on the emptying pipeline 5; the distance between the bottom end of the drain pipe 3 and the bottom end of the drain box body is 200mm to 400mm.

The working principle is as follows: the water that condenses in the during operation gas pipeline enters into the water seal chamber through drain pipe 3, and along with the continuous rising of the surface of water in the water seal chamber 1, the water in the water seal chamber 1 enters into overflow chamber 2 through overflow mouth 4 in, regularly observes the water level in the overflow chamber 2 through the mouth that draws water to regularly discharge through the mouth 2 that draws water.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
