Natural gas is generally mined from nature. In the mining, it is inevitable that the natural gas contains sandstone granules due to the vigorous air flow. In addition, natural gas transport pipes are generally made of steel, and over the years, rusted metal oxide debris inside them is carried out in the air. Therefore, before liquefaction of natural gas and during transportation, it is necessary to filter the sandstone granules and metal-oxidized granules to ensure its cleanliness.

Conventionally, it is common to filter the granules in the liquefied gas using a liquefied gas filter. Liquefied gas filters are widely used in gas fields such as metallurgy, chemical industry, petroleum, papermaking, pharmaceuticals, food, mining, electric power, cities, and households. A liquefied gas filter is an essential device in the piping of medium transport and is usually attached to the import end of pressure reducing valves, pressure diverging valves, positioning valves or other devices for it to remove impurities in the medium. It ensures the normal use of valves and devices and reduces equipment maintenance costs.
ところが、従来の液化ガス濾過器は下記の欠陥がある。

However, the conventional liquefied gas filter has the following defects.
1) During the transportation of the liquefied gas, after the granules were filtered by the filtration mesh, they stayed on the filtration mesh and did not fall off immediately, and the airflow was uniform and continuous, and the retained matter was pushed by the airflow. Due to the repulsive force of the filtration mesh and the balance of dynamics, it is difficult for the retained matter to fall off immediately and fall into the filtration tube, and the filtration mesh is gradually blocked, and the resistance to the air flow due to the filtration of the filtration tube. Becomes larger.
2) Small granule debris hangs in the mesh of the filter mesh, and the filter mesh is blocked by the small granules.

The Y-type liquefied gas filter of the present application, which adopts the above technical proposal, specifically has the following effects with respect to the conventional technology.
1) When the Y-type liquefied gas filter disclosed in the present invention is adopted, the flexible connection of the deformed ring allows the filter plate to vibrate when it receives a flow of liquefied gas, thereby causing the surface of the filter plate to vibrate. Rigid granules and blocked objects can be dropped.
2) When the elastic member is directly connected to the filter plate and the filter plate is supported by the elastic member, when the filter plate vibrates due to the movement of the air flow, the elastic member can move in the opposite direction and move in conjunction with the elastic member. The frequency of vibration is further expanded by the expansion and contraction repulsion of. As a result, the filter plate can vibrate at a high frequency, and all the accumulated matter and the blocked matter on the surface of the filter plate are dropped into the filter cylinder.
3) The energy that the airflow impacts the filter plate can be accumulated. Without the collection of elastic energy by the elastic member, the vibration is easily absorbed by the deformation ring. Therefore, after the elastic member absorbs a large amount of energy, the amplitude can be repeatedly expanded in the form of compression / repulsion to increase the vibration width of the filter plate.

The planes of 22 and the baffle plate 4 both face the entrance 11. The baffle plate 4 directly faces the air flow of liquefied gas on an impermeable plane. In this way, a large pressing force is formed on the filter plate 20, so that
The entire filter plate 20 can be more easily pushed and moved by the airflow, resulting in a larger vibration width. That is, the influence of the liquefied gas stream on the vibration of the filter plate 20 is increased.

There is a gap between the and columnar groove 221. A distance is provided between the baffle plate 4 and the outer end of the support spindle 22. By providing the gap and the spacing distance, when the airflow impact is received by the air receiving plate 4, the air receiving plate 4 swings confusingly with a small vibration width on the support spindle 22 due to the gap and the spacing distance. The vibration direction due to is more random and confusing, the direction of the filter plate 20 is more random, the vibration direction of the granules on the surface of the filter plate 20 is more mixed, and the small granules blocked in the mesh are also shaken off. It prevents the filter plate 20 from becoming immobile, avoiding the sustained stable airflow balancing the dynamics within the filter.

As shown in FIG. 7, the diameters of the support inner shaft 41, the columnar groove 221, the roller 40 and the ball groove 220 increase in order. When the roller 40 is fitted into the ball groove 220, the roller 40 is limited to the inside of the ball groove 220 and cannot be inserted into the columnar groove 221 to exhibit the function of fixing the bottom of the baffle plate 4. You can avoid that escape. By making the diameter of the columnar groove 221 larger than the support inner shaft 41, the support inner shaft 41 can form a cone-shaped swinging region along the opening of the columnar groove 221, and the vibration is filtered by the support spindle 22.

As shown in FIG. 8, such a filtration method depends on some hardware in its application. Hardware includes multiple pipes through which liquefied gas flows, pneumatics, pulse controllers, one-way valves and the above-mentioned filters. The pulse controller is connected to the pneumatic machine. The pneumatic machine and the one-way valve are connected in parallel in the pipe. The pneumatic machine and the one-way valve are connected to the inlet 11 of the same filter. The pneumatic machine and the one-way valve are connected in parallel.

Specifically, the filtration method includes the following steps.
Step 1: In the flow splitting process, the liquefied gas is divided into two airflows by a branch pipe, and the airflows enter the one-way valve and the pneumatic machine respectively, and the airflow forms a uniform flow with the one-way valve. The airflow forms a pulsed flow with a pneumatic machine.
Step 2: In the generation of pulse flow, the pulse controller of the pneumatic machine controls the pneumatic machine to repeatedly compress the liquefied gas to form a high-pressure air flow, and intermittently emit the high-pressure air flow to pulse. Forming a stream and letting it flow into the filter.
Step 3: Generate a uniform flow, letting the liquefied gas pass through a one-way valve to form a uniform liquefied gas stream and let it flow into the filter.
However, step 2 and step 3 are steps performed at the same time, and there is no order before and after.
Step 4: In vibration filtration, when a uniform flow continuously enters the inlet 11 of the filter and a pulse flow also enters, the high pressure in the filter repels and closes the one-way valve to pulse. The flow is impacted on the filter plate 20 and / or the baffle plate 4 of the filter, the filter plate 20 is vibrated by the deformation ring 21, and the elastic member 5 is vibrated to increase the frequency and width of the vibration.
Step 5: Shaking off the stagnant material, vibrating the filter plate 20 at a high frequency, shaking off the stagnant material fitted in the mesh, dropping the stagnant material and dropping it into the filter cylinder 13. ..

過器内へ流動させて（90%以上は均一流の形で濾過器内に流入させる）、液化ガス整体は
持続的に濾過済状態となっている。
The liquefied gas can be continuously passed through the one-way valve, and a large amount of uniform flow is allowed to flow from the one-way valve into the filter (90% or more flows into the filter in the form of a uniform flow). , The liquefied gas manipulative treatment is continuously filtered.
小部分の分岐（液化ガス気体の残った10%）を空圧機内に進入させて、空圧機内で高圧を
形成させて、その後、高圧気流を放出させる手法でパルス流を形成して、気流衝撃によっ

と振動させることができる。
A small part of the branch (the remaining 10% of the liquefied gas) is allowed to enter the pneumatic machine to form a high pressure in the pneumatic machine, and then a pulse flow is formed by a method of releasing a high pressure air flow to form an air flow. The impact can upset the dynamic balance of the stationary mesh in the filtration mesh and cause the filtration mesh to vibrate clearly.
均一流を一方向弁に通過させるため、パルス流が発生すると、一部が一方向弁内に反発す
るようになって、それによって、一方向弁が閉弁され、すべてのパルスが均一流を経て戻
るのを避けて、一方向弁を閉弁する手法でパルス流の濾過器内への持続的な流動を防止し
て、これによってパルス効果を向上する。
In order to pass the uniform flow through the one-way valve, when a pulse flow is generated, a part of it repels the inside of the one-way valve, which closes the one-way valve and all the pulses make the uniform flow. The technique of closing the one-way valve prevents the pulse flow from continuously flowing into the filter, thereby improving the pulse effect, avoiding the return.
液化ガス気流が濾過器の入口11に直接に接するのと比べて、本方法は、均一流が長時間で
迎風板4を押すと、迎風板4が一方向に濾過板20を押して動態バランスを形成するようにな
る可能性が高く、濾過メッシュ2において濾過板20の振動幅が小さくて、かつ振動周波数
も低いという利点がある。
In this method, when the uniform flow pushes the baffle plate 4 for a long time, the baffle plate 4 pushes the filter plate 20 in one direction to balance the dynamics, as compared with the case where the liquefied gas stream directly contacts the inlet 11 of the filter. There is an advantage that the filtration plate 20 has a small vibration width and a low vibration frequency in the filtration mesh 2 because it is likely to be formed.
また、パルス流によって瞬間で大きな衝撃力を生じ、上記の動態バランスを破壊すること
ができる。これによって迎風板4に新たな錯乱で無規則の揺動動作を発生させ、新たな振
動方向をもたらし、これにより濾過板20を振動させる。
In addition, the pulse flow instantly generates a large impact force, which can destroy the above-mentioned dynamic balance. As a result, the air receiving plate 4 is caused to cause an irregular rocking motion due to new confusion, and a new vibration direction is brought about, thereby vibrating the filter plate 20.
上記のステップ2において、空圧機により液化ガスを0.2〜0.27MPa、即ち2〜2.7倍の標準
大気圧に圧縮させる。該気圧範囲は高圧鍋の内気圧に近似して、安全であり、爆発する恐
れがなく、それとともに、発生した高圧気体の衝撃力も十分で、パルス流によって迎風板
4を揺動させるのに十分である。
In step 2 above, the pneumatic gas is compressed to 0.2 to 0.27 MPa, that is, 2 to 2.7 times the standard atmospheric pressure. The air pressure range is close to the internal pressure of a high-pressure pan, which is safe and does not cause an explosion. At the same time, the impact force of the generated high-pressure gas is sufficient, and the baffle plate is provided by a pulse flow.
Enough to rock 4.
上記空圧機が高圧気体を放出してパルス流を形成する時間間隔は0.8〜2sとする。一般的
には、1回の気流衝撃後、バネ5の振動可能な時間は3〜4s程度である。その時間が経って
から、バネ5の振動が著しく弱る。したがって、その振動が弱る前に、直ちに衝撃力を補
充して、衝撃させて、振動を強めることによって、濾過板20が持続的に振動でき、且つ振
動力が強い。
The time interval at which the pneumatic machine emits high-pressure gas to form a pulse flow is 0.8 to 2 s. Generally, the vibrating time of the spring 5 is about 3 to 4 s after one airflow impact. After that time, the vibration of the spring 5 weakens significantly. Therefore, before the vibration weakens, the filter plate 20 can be continuously vibrated and the vibration force is strong by immediately replenishing the impact force, causing the impact, and strengthening the vibration.
またパルス流の衝撃力が濾過器内でパルスバランスを取ることを避けるために、高圧気流
の放出間隔時間が0.8〜2sの間における任意のランダム時期である。即ちパルスの時間は
例えば、第1回のパルス後の1.2sに第2回のパルスが生じる、第2回のパルス後の1sに第3回
のパルスが生じる、第3回のパルス後の1.9sに第4回のパルスが生じる、……などがあげら
れる。
Also, in order to prevent the impact force of the pulse flow from balancing the pulse in the filter, the emission interval time of the high-pressure airflow is an arbitrary random time between 0.8 and 2 s. That is, the pulse time is, for example, 1.2 s after the first pulse, the second pulse occurs, 1 s after the second pulse, the third pulse occurs, and 1.9 after the third pulse. The 4th pulse is generated in s, and so on.
パルス間隔はランダムにされることにより、有効的にパルスの動態バランスの取ること（
毎回のパルス衝撃による振動は近似）を避けることができる。
By making the pulse intervals random, the dynamic balance of the pulses can be effectively balanced (
Vibration due to each pulse impact is approximate) can be avoided.
