Description
Technical Field
The utility model relates to a two membrane gas holder safety arrangement.
Background
The double-film gas holder is generally used for storing neutral gas such as methane, oxygen and the like, and the main body of the double-film gas holder consists of an outer film, an inner film and a bottom film which are made of specially processed polyester materials. The inner space of the inner membrane is a storage space, and the space between the outer membrane and the inner membrane is a pressure regulating space. When the gas stored in the inner film is reduced, air is injected between the outer film and the inner film to balance the pressure intensity in the cabinet and stabilize the rigidity of the outer film; when the gas stored in the inner film is increased, the air between the outer film and the inner film is extruded to increase the air pressure, and at the moment, partial air needs to be released to balance the pressure, so that the gas cabinet is prevented from exploding due to overpressure.
At present, overpressure release of air is mostly achieved by means of a safety water seal. The air inlet pipe is inserted into a sealed water body at ordinary times, and the water body isolates the inner space and the outer space of the air inlet pipe; after the air pressure is increased, the liquid level in the air inlet pipe is pressed to fall to the pipe end of the air inlet pipe, so that the inside and the outside of the air inlet pipe are communicated, and the air can be released from the air inlet pipe. When the safety protection structure is used, the water body for sealing needs to be replaced by the antifreeze in seasons with low air temperature. However, the replacement of the antifreeze is not a simple method, and because the antifreeze also has an ice point, the antifreeze is also frozen when the temperature drops dramatically, which leads to the loss of the safety protection structure, and the double-film gas cabinet still has a great risk of explosion.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a can release pressure to the superpressure and form the double insurance, show the double-membrane gas holder safety arrangement who reduces the superpressure explosion risk.
In order to solve the technical problem, the technical scheme of the utility model is that: the double-membrane gas holder safety protection device comprises a pressure stabilizing tank, wherein an air inlet pipe and an air outlet pipe are fixedly arranged on the pressure stabilizing tank, sealing liquid is filled in the pressure stabilizing tank, and the inner end of the air inlet pipe extends downwards to be arranged below the liquid level of the sealing liquid; the air inlet pipe is connected with a safety valve, the air outlet of the safety valve is connected with the pressure stabilizing tank, and the air outlet of the safety valve is higher than the liquid level of the sealing liquid.
As a preferable technical scheme, a liquid level meter is arranged on the pressure stabilizing tank.
By adopting the technical scheme, the double-membrane gas holder safety protection device comprises a pressure stabilizing tank, wherein an air inlet pipe and an air outlet pipe are fixedly arranged on the pressure stabilizing tank, sealing liquid is filled in the pressure stabilizing tank, and the inner end of the air inlet pipe extends downwards to be arranged below the liquid level of the sealing liquid; the air inlet pipe is connected with a safety valve, the air outlet of the safety valve is connected with the pressure stabilizing tank, and the air outlet of the safety valve is higher than the liquid level of the sealing liquid. The utility model discloses set up water seal and relief valve duplicate insurance simultaneously, the water seal can guarantee normally admit air and the sealed in pressure regulating space in the two membrane gas holder. When the air pressure in the pressure regulating space is increased, the air pressure directly passes through the air inlet pipe to act on the liquid level of the sealing liquid, the liquid level of the sealing liquid in the air inlet pipe is pressed to be reduced to the inner end face of the air inlet pipe, and the air inlet pipe is communicated with the outside and the inside to realize pressure release. When the sealing liquid freezes, the sealing liquid can effectively seal the inner end of the air inlet pipe, and the safety valve is opened after the air pressure is continuously increased to the opening pressure, so that pressure relief is realized. The sample utility model forms double insurance for overpressure pressure relief, and obviously reduces the risk of overpressure explosion.
Drawings
The drawings are only intended to illustrate and explain the present invention and do not limit the scope of the invention. Wherein:
fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure: 1-a surge tank; 2, an air inlet pipe; 3-air outlet pipe; 4-sealing liquid; 5-safety valve; 6-liquid level meter.
Detailed Description
The invention is further explained below with reference to the drawings and examples. In the following detailed description, exemplary embodiments of the invention are described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
As shown in fig. 1, the double-membrane gas holder safety protection device comprises a surge tank 1, wherein an air inlet pipe 2 and an air outlet pipe 3 are fixedly arranged on the surge tank 1, conventionally, the air inlet pipe 2 is connected with a pressure regulating space of the double-membrane gas holder, and the air outlet pipe 3 is positioned on the upper part of the surge tank 1. The pressure stabilizing tank 1 is filled with sealing liquid 4, and the inner end of the air inlet pipe 2 extends downwards to a position below the liquid level of the sealing liquid 4. The air inlet pipe 2 is connected with a safety valve 5, the air outlet of the safety valve 5 is connected with the pressure stabilizing tank 1, and the air outlet of the safety valve 5 is higher than the liquid level of the sealing liquid 4.
The embodiment is provided with a water seal and a safety valve 5, and the water seal can ensure normal air inlet and the sealing of the pressure regulating space in the double-membrane gas holder. When the internal gas pressure of pressure regulating space increases, atmospheric pressure directly passes through intake pipe 2 acts on the liquid level of sealing liquid 4, the liquid level pressurized reduction of sealing liquid 4 in intake pipe 2 arrives the interior terminal surface department of intake pipe 2, the inside and outside intercommunication of intake pipe 2 realizes the pressure release. When the sealing liquid 4 freezes, the sealing liquid 4 can effectively seal the inner end of the air inlet pipe 2, and the safety valve 5 is opened after the air pressure is continuously increased to the opening pressure, so that the pressure is released.
Thus, the embodiment forms double insurance for overpressure pressure relief, and obviously reduces the risk of overpressure explosion. Preferably, the opening pressure of the safety valve 5 and the pressure to which the liquid level of the sealing liquid 4 is subjected when it falls to the inner end of the intake pipe 2 are set to be equal. The air outlet of the safety valve 5 is higher than the liquid level of the sealing liquid 4, so that the influence of freezing of the sealing liquid 4 on the pressure relief of the safety valve 5 can be avoided.
