Description
Technical Field
The utility model relates to an automatic drainage device especially relates to an automatic drainage device of frost-proof hydrogen.
Background
The hydrogen is sent to the boiler to overflow and need to discharge condensed water for several times every shift, and the overflow port is very easy to freeze due to low temperature in winter. If the steam pipe is simply led out from one end of the drain valve, the steam pipe is communicated and opened, although the steam pipe is easy to freeze, hydrogen is easy to discharge from the vent, and great hidden danger is brought to production safety, so that the design of the automatic drain device capable of preventing freezing and hydrogen leakage is particularly necessary.
SUMMERY OF THE UTILITY MODEL
The utility model discloses hydrogen automatic water discharging device is used for boiler row's comdenstion water, and the steam that utilizes the boiler to produce prevents that the comdenstion water from freezing, utilizes the automatic comdenstion water that discharges of hydrogen.
Automatic drainage device of hydrogen, the water sealed tank is the cylindrical jar of vertical setting, the inside of water sealed tank is provided with "U" venturi tube, the entry and the export of U "venturi tube all stretch out the water sealed tank from water sealed tank up end, the side of water sealed tank is provided with the overflow mouth, the up end of water sealed tank has inserted the hydrogen inlet tube, the vertical setting of hydrogen inlet tube, the upper end of hydrogen inlet tube communicates outside hydrogen pipeline, the lower extreme of hydrogen inlet tube is located under the overflow mouth, the pressure differential of hydrogen inlet tube and water sealed tank equals the pressure differential of hydrogen and external atmospheric pressure, make the water in the hydrogen inlet tube can not inhale the hydrogen pipeline because of outside hydrogen pressure.
Preferably, the water-sealed tank is made of stainless steel.
Preferably, the upper ends of the hydrogen inlet pipes are connected by flanges.
Preferably, the distance between the bottom end of the U-shaped pipe and the bottom surface of the water sealed tank is one fifth of the height of the water sealed tank.
Has the advantages that: the utility model discloses a set up "U" venturi tube in the water seal tank, introduce the vapor that produces in the production and "U" venturi tube gives the water heating in the water seal tank, prevented that the water in the water seal tank from freezing because of the temperature is low, through setting up the water seal, prevented the leakage of hydrogen, ensured the security of production.
Drawings
FIG. 1 is a schematic structural view of the automatic hydrogen gas drainage device of the present invention;
fig. 2 is a schematic view of the connection relationship between the hydrogen automatic drainage device and the external hydrogen pipeline.
Detailed Description
The present invention will be further explained with reference to the specific embodiments, as shown in fig. 1 to 2, the automatic hydrogen gas drainage device includes a water-sealed tank 1, the water-sealed tank 1 is a vertically arranged cylindrical stainless steel tank, the stainless steel is corrosion resistant, and the service life of the water-sealed tank 1 is prolonged; the water-sealed tank 1 is internally provided with a U-shaped pipe 2, the inlet and the outlet of the U-shaped pipe 2 extend out of the water-sealed tank 1 from the upper end face of the water-sealed tank 1, water vapor is introduced from one end of the U-shaped pipe 2 and is discharged from the other end, the distance between the bottom end of the U-shaped pipe 2 and the bottom surface of the water-sealed tank 1 is one fifth of the height of the water-sealed tank 1, the U-shaped pipe 2 extends into the water-sealed tank 1 to be heated more uniformly, the side face of the water-sealed tank 1 is provided with an overflow port 3, a hydrogen inlet pipe 4 is inserted from the upper end face of the water-sealed tank, the hydrogen inlet pipe 4 is vertically arranged, the upper end of the hydrogen inlet pipe 4 is communicated with an external hydrogen pipeline 6, the upper end of the hydrogen inlet pipe 4 is connected with the external hydrogen pipeline 6 through a flange, the flange is connected to facilitate the pipeline disassembly, the sealing performance is, make water level 5 in the hydrogen inlet tube 4 be higher than the liquid level height in the water-sealed tank 1, the water pressure in the hydrogen inlet tube 4 is higher than the water pressure in the water-sealed tank 1, and the pressure differential of hydrogen inlet tube 4 and water-sealed tank 1 equals the pressure differential of hydrogen and external atmospheric pressure for water in the hydrogen inlet tube 4 can not inhale hydrogen pipeline 6 because of outside hydrogen pressure.
The working process of the utility model is as follows: introducing steam from one end of the U-shaped pipe 2 and discharging the steam from the other end of the U-shaped pipe 2 to heat water in the water seal tank 1, so that the water is prevented from freezing due to low temperature, condensed water is fed into the hydrogen water inlet pipe 4, the height of the water level 5 is increased due to the increase of the condensed water, the balance between the water seal pressure and the hydrogen pressure is broken, the condensed water in the hydrogen water inlet pipe 4 flows into the water seal tank 1, the condensed water starts to flow out from the overflow port 3 until the water seal pressure is balanced with the hydrogen pressure again, the water level 5 is stable, and the overflow port 3 stops discharging water; when the operation is carried out for the first time, water with the liquid level reaching the position of the overflow port 3 is injected into the water-sealed tank 1 in advance, and then the operation is carried out.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
