JPS61157321A - Gas separator for gas trap - Google Patents

Abstract

PURPOSE:To obtain a gas separator for rapidly leading out and diffusing gas accumulated to the upper part of a water sump chamber, by forming the water sump chamber by a casing and opening the drain pipe of a gas trap to water in a lower part while securing a predetermined amount of water and providing an exhaust pipe to the upper par of said water sump chamber. CONSTITUTION:The fluid flowed in from a gas trap 1 enters the water sump chamber 5 of a gas separator 3 and exhausted higher in the air from the upper part of the water sump chamber 5 through an exhaust pipe. Water is flowed out to the outside from a lower opening part 8 through a drain passage 9 while a predetermined amount of water is held in the water sump chamber 5. As mentioned above, combustible gas or toxic gas can be rapidly raised and diffused by such a simple structure that a U-shaped trap or a drain passage having an overflow structure is provided.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas trap that automatically removes liquid such as condensed water from a gas usage device or transport pipe without allowing the gas to escape.

Air traps have traditionally been used to automatically remove condensate from compressed air systems. An air trap houses a float in a valve chamber and uses this float to open and close a drain port. However, when liquid flows into the valve, the liquid level rises, causing the float to float up and open the drain port, allowing the liquid in the valve chamber to flow out. Then, when the liquid flows out and the liquid level drops again, the float descends to close the drain port and prevent gas from flowing out (leakage).

Conventional technology Although this air trap can be used for flammable and toxic gases, taking into account the danger in the event of a gas leak,
Gas traps with excellent sealing performance are generally used. Gas traps are structurally similar to air traps.

However, since gas traps handle corrosive fluids, it is inevitable that the valve portion will corrode and begin to leak within a relatively short period of time.

Therefore, it is necessary to take safety measures to prevent dangerous gas from leaking from the gas trap.

The technical problem of the present invention is to obtain a casserosol which separates the hazardous gas leaking from the gas trap from the wastewater and leads it high into the air where it is dispersed and becomes f#I thin.

Means for Solving the Problems The technical means of the present invention taken to solve the above technical problems are: 1) A) Forming a water reservoir seedling with a casing and passing it through a drainage passage with a zero-shaped trap or an overflow structure. Excess water is allowed to flow outside while ensuring a specified amount of water in the water reservoir; The system was designed so that the gas that had accumulated in the upper part of the water reservoir was discharged high into the air.

action The operation of the above technical means is as follows.

The fluid discharged from the gas trap, usually a liquid such as water, but also containing gas if the gas trap leaks, is introduced into the F section of the water reservoir chamber. The water storage chamber is connected to the outside through a drainage passage with a U-shaped V4 structure or an overflow structure. During installation, water is sometimes injected from the exhaust pipe, and after that, water flows in from the gas trap, so a predetermined amount of water is inside. water is always available.

Therefore, when water flows in from the gas trap, excess water flows out through the drainage passage of the diagonal tube structure or overflow structure while maintaining a predetermined amount of water in the water reservoir. When gas flows in, it collects in the upper part of the water storage chamber, is led out high into the air through the exhaust pipe, dispersed into the atmosphere, and becomes diluted.
Flammable gases are prevented from catching fire, and toxic gases are weakened.

When the drainage passage has a U-shaped pipe structure, the water reservoir and the outlet of the drainage passage are sealed with water, so that even gas having a higher specific gravity than air will not leak out.

If the drainage passage has an overflow structure, it can be applied to gases whose specific gravity is smaller than air, and the exhaust pipe and drainage passage form a chimney-like structure in the atrium, allowing the gas to quickly rise and diffuse through convection. can.

Effect of the invention The Honmaru area produces the following special effects.

Since the gas separator of the present invention has a water seal pot structure, it has a simple structure and can be made robust and at low cost.

If a part of the casing is made transparent so that the water level in the water storage chamber can be seen, leakage from the gas trap can be detected early and the smoker replaced appropriately.

Embodiment An actual IM example showing a specific example of the above technique Ifj-like means will be explained.

(Example 1 See FIG. 1) The drain pipe 2 of the gas trap 1 is introduced into the water reservoir chamber 5 formed in the casing 4 of the gas separator lake 3.

Drainage i! 2 is opened to the liquid in the water reservoir 5. An exhaust port 6 is provided in the upper part of the casing 4 and an exhaust pipe 7 is connected thereto. The exhaust pipe 7 has a length of 5 to 10 meters.

The gas is directed high into the air. casing 4
A frontage 8 is provided on the lower side surface of the opening 8, and a drainage passage 9 having an oval pipe structure is formed at the end of the opening 8.

After installing the gas separator 3, water is injected from the exhaust pipe 7. The fluid flowing from the gas trap 1 enters the water reservoir 5 of the gas separator 3, and the gas accumulates at the upper part of the main reservoir 5 and is discharged into the air through the exhaust pipe 7. The water flows out from the lower opening 8 through the drainage passage 9 to the section 9'F while holding a predetermined amount of water 11 in the water reservoir 5.

(Embodiment 2 See FIG. 2) This is a drainage passage 29 having an overflow structure, and components corresponding to those in FIG. 1 are given the same reference numerals and detailed explanations will be omitted.

A partition wall 30 is formed in the water reservoir seedling 25 of the gas separator 23. An opening 28 is provided in the upper part of the partition wall 30, and a drainage passage 29 connected to the opening 28 is formed on the surface of the cage jig 4.

The gas is discharged high into the air through the exhaust pipe 7, and the water flows out through the opening 28 and the drainage passage 29 to the outside.
