Abstract

PROBLEM TO BE SOLVED: To extend the service life of a seal device, by removing the unnecessary substance fixed on the inner wall, without stopping the service. SOLUTION: At the upper side of a piston oil groove 3, a corrugated removing member 5 installed to a back plate 6 is provided, and it is squeezed to an inner wall 1 together with the back plate 6 by an air cylinder 7. The feeding of an operation air to the air cylinder 7 is controlled by a solenoid valve 12, the solenoid valve 12 is opened when a switch 11 is made ON by the high inner pressure of a piston 2 at its rising time, it feeds the operation air to the air cylinder 7 when the switch 11 is ON, and the removing member 5 rubs the inner wall 1 to rake out the unnecessary substance together with the rise of the piston 2. In this case, a seal oil attached on the inner wall which is raked out together is filtered by a filter 9, so as to be recovered. The corrugated removing member 5 contacts to the inner wall 1, even though the inner wall 1 has an uneven surface.

2. Description of the Related Art City gas, coke oven gas, and the like are produced regardless of day and night. However, since the amount of consumption depends on demand, in many cases, they are supplied once after being stored in a gas holder. . This type of gas holder is generally in the shape of a polygonal cylinder or a cylinder, and a piston disposed therein rises and falls according to an increase or decrease in the amount of stored gas. That is, the gas is normally stored below the piston, and the piston rises when the gas amount increases, and descends when the gas amount decreases. At this time, since the piston moves up and down along the inner wall of the gas holder, a so-called piston oil groove 3 mainly filled with seal oil is formed between the outer periphery of the piston and the inner wall of the gas holder, as shown in FIG. 2, for example. A sealing device is provided. According to this sealing device, the sealing oil in the piston oil groove 3 oozes between the inner wall 1 of the gas holder and the oil film to form an oil film, and the oil film serves as a gas seal portion 4 to seal gas.

The by-product gas such as coke oven gas contains corrosive components such as sulfur and nitrogen compounds and dust floating in the gas. Corrosion products and dust such as sulfur iron and ferrocyanide may adhere to the inner wall of the gas holder. Accordingly, the frictional resistance between the seal device of the piston and the inner wall of the gas holder increases due to the stuck undesired matters, and there is a concern that the piston may not be moved up and down or the seal device may be deteriorated early. Therefore, conventionally, a worker has stopped using the gas holder regularly with a tool such as a spatula in order to remove the stuck unnecessary matter. Also, during this unnecessary work, it is necessary to pressurize air into the gas holder and hold the piston at a predetermined position.

[0004] However, if the use of the gas holder is periodically stopped for the purpose of removing unnecessary substances, there is a problem in terms of resources and labor, such as preparing a spare gas holder and securing workers. In addition, there are many problems in terms of efficiency in a work relying on a small tool such as a spatula for a large gas holder having a geometric volume of tens of thousands of cubic meters. In addition, various devices for removing unnecessary substances have been proposed for these problems, but those which can be used practically and which have sufficient effects are desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the hydrostatic gas holder according to the present invention will be described. FIG. 1 shows details of the cylindrical hydrostatic gas holder of the present embodiment, particularly in the vicinity of a sealing device. This sealing device is also formed by forming a piston oil groove 3 on the outer peripheral portion of the piston 2, that is, inside the inner wall 1, similarly to the conventional sealing device using FIG.
The oil film that oozes out from the oil groove 3 and is formed in the gap with the inner wall 1 becomes the gas seal portion 4. Then, the gas is stored below the piston 2 sealed in this way, and the piston 2 rises when the gas amount increases, and moves down when the gas amount decreases. That is, the internal pressure of the gas holder is maintained substantially at a pressure obtained by dividing the weight of the piston 2 by its sectional area.

Next, the operation of this embodiment will be described. First, the setting of the predetermined internal pressure that separates ON / OFF of the switch 11 will be described. As described above, when the piston 2 does not move up and down, the internal pressure of the gas holder is kept constant. However, when the gas amount increases and the piston 2 rises, the internal pressure temporarily increases and the gas amount decreases. Then, when the piston 2 descends, the internal pressure temporarily decreases. That is, the weight of the piston W p, the frictional resistance W fd of the gas seal portion, the cross-sectional area of the piston and S, piston self weight W p and the gas seal portion frictional resistance when the piston 2 is raised, as shown in FIG. 3a W fd acts in the same direction, so the internal pressure at that time is the piston's own weight W p
And the pressure obtained by dividing the sum of the frictional resistance W fd of the gas seal portion and the piston cross-sectional area S. On the other hand, because there is a piston self weight W p and the gas seal portion frictional resistance W fd when the piston 2 is lowered as shown in FIG. 3b acts in the opposite direction, the internal pressure at that time the piston own weight W p from the gas seal portion frictional resistance The pressure is obtained by dividing the value obtained by subtracting W fd by the piston cross-sectional area S. The internal pressure when this piston 2 rises, the switch 1
1 is configured to be turned on.

Therefore, when the piston 2 rises, as shown in FIG. 1A, the switch 11 is turned on with an increase in the internal pressure, and as a result, the solenoid valve 12 is opened to supply working air to the air cylinder 7, Corrugated removal member 5
Is pressed against the inner wall 1. In other words, the removing member 5 is attached to the inner wall 1
It moves upward while being pressed against the inner wall 1, and scrapes off the undesired matter that has adhered to the inner wall 1 and the attached seal oil. The scraped seal oil and unnecessary substances fall into the filter 9, but only the seal oil is filtered out of the filter 9 and collected in the oil groove 3, and the unnecessary substances remain on the filter 9.
