Industrial gas contains a large amount of saturation waters, and in course of conveying, because variation of temperature, saturation water can be condensed into liquid water and deposit, and liquid water is many can to cause adverse effect to pipeline, must in time discharge.Simultaneously, because the variation and the accidental event of operating mode, the pressure of coal gas can produce fluctuation, even can surpass pipeline and coal gas user's ability to bear.On the industrial gas pipeline, in order to discharge condensed water, certain distance is provided with hydathode at interval.In hydathode, turnover water pipe is inserted in the water, and the pipe water surface interior and that pipe is outer has a height difference.The pressure that this height difference forms is enclosed in coal gas in the pipeline, promptly usually said water seal, and its structure is as shown in Figure 3.And the condensed water in the gas pipe line can flow into hydathode, and the water surface surpasses drain opening, and water just flows out from drain opening automatically.When pressure is fluctuating in normal scope, coal gas can not leak.But when gas pressure is too high, will wash water seal open, leak in the air in a large number.A large amount of coal gas that leak are all gushed out from waste pipe.The coal gas that spills accumulates in ground, and personnel all around suck coal gas will cause poisoning.In a single day common water-sealed type hydathode runs into the coal gas of big pressure, will be breakdown; Owing to the water yield in the such-and-such reason water seal reduces, the bearing capacity of water seal descends, and coal gas also can leak out from hydathode.The normal discharge device is difficult to accomplish timely moisturizing by artificial recharge.To such an extent as to it is hydathode water seal moisturizing that some places have to adopt running water.The result causes a large amount of wastes of water, and sewage overflows, befouling environment.The water seal puncture, when coal gas is gushed out, the water in the water seal can be taken out of in a large number.After causing gas pressure to recover, owing to the water seal lack of water is sealed incessantly coal gas, coal gas continues a large amount of the leakage.Usually, gas pressure sharp increase is the short time.If the hydathode water seal is lack of water not, when gas pressure lowers, the water of water seal still can be sealed coal gas, and the coal gas amount of leakage also is difficult to damage.If a large amount of water has been lost in water seal, cause hydathode to continue leakage gas, long-time, a large amount of gas leakage, this is only the serious root of harm.

Therefore, improve the Security of hydathode, avoid gas leakage to hurt sb.'s feelings, have only the resistance to sparking that improves water seal, can in time be hydathode water seal moisturizing simultaneously, allows water seal remain enough bearing capacities.

The model utility content

The purpose of this utility model be to provide a kind of be used for gas pipe line, can bear the hydathode that gas pressure impacts, can be used for the draining of other gas pipeline or container equally.

The purpose of this utility model is achieved through the following channels: hydathode is made up of one or more independent cavity, the outlet pipe of hydathode previous stage chamber is inserted in the water of next stage chamber, is evenly equipped with diffusion porosity on the tube wall of the turnover water pipe end of hydathode inner barrel; Chamber interior has dividing plate that chamber is divided into two districts up and down, and independent diffusing tube is arranged on the dividing plate, is evenly equipped with diffusion porosity on the independent diffusing tube tube wall; Above-mentioned two kinds of structures can be used simultaneously also can select each chamber or a pipeline that is used in hydathode.On the water-adding pipe of hydathode cylindrical shell upper end automatic water-replenishing device is installed.The one-level intake pipe is located at outside the hydathode cylindrical shell.

The utility model is a kind of hydathode, has the advantage of normal discharge device: simple in structure, and no movable members, reliable performance.The utility model inside has the diffusion pressure reduction structure simultaneously, and many apertures are arranged on turnover water pipe or the diffusing tube in cylindrical shell, can make gas pressure obtain slowly-releasing, and big air mass becomes small bubble, and the quality and the speed of bubble diminish, and are difficult for water is gone out from water seal.Water loss when water seal is breakdown in the water seal is minimum.Behind the part water loss, automatic water-replenishing device plumbing device moisturizing in time.Make hydathode can have enough water yields to seal coal gas, prevent that gas pressure from recovering after, continue to leak in large quantities.Thereby improved the Security of hydathode, avoided the hurt sb.'s feelings generation of incident of gas leakage.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is another embodiment's of the utility model a structural representation;

Accompanying drawing 3 is the structural representation of existing normal discharge device.

Embodiment

When the pressure generation big ups and downs of gas pipe line, pressure has surpassed the maximum bearing ability of hydathode water seal, and coal gas will directly leak into the outside by hydathode.This situation is called " puncture ".After the normal discharge device was breakdown, the coal gas of going out can be taken away water a large amount of in the water seal, caused water seal to puncture the back and again sealed incessantly coal gas because of lack of water.Coal gas continues to leak, and causes injury to the people.The utility model adopts the principle of " diffusion decompression ", and the diffusion pressure reduction structure of band porous is arranged in hydathode.The diffusion pressure reduction structure can make superpressure coal gas spread gradually and reduce pressure, makes big air mass become small bubble.Alleviate the impact force of superpressure coal gas, avoided more water to be taken out of hydathode.Simultaneously, after the moisture loss,, recover the ability of water seal as early as possible by the moisturizing of the timely plumbing device of automatic water-replenishing device.

Embodiment one, with the two-stage water seal is example, as shown in Figure 1, the utility model hydathode is made up of two independent cavity, be respectively hyperbaric chamber 2 and low pressure chamber 8, the turnover water pipe 11 of low pressure chamber 8 (being the outlet pipe in hyperbaric chamber 2) is inserted in the water of low pressure chamber 8, is evenly equipped with diffusion porosity 7 on the tube wall of turnover water pipe 11 ends; Chamber interior has dividing plate that hyperbaric chamber 2 is divided into two districts up and down, and independent diffusing tube 12 is arranged on the dividing plate, is evenly equipped with diffusion porosity 7 on independent diffusing tube 12 tube walls.
