Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to gas holder equipment suitable for storing large-capacity gas, in which a waterless gas holder can be used in a multiple unit movement system.

A well-known waterless gas holder has a piston built into the cylindrical or polygonal holder body with a roof, and the lower part of the piston is filled with stored gas. is designed to move up and down inside the holder. The gas pressure is kept constant by the load on the piston, and when the gas reaches the storage capacity limit of the holder, that is, the piston exceeds the allowable rise limit, the gas is automatically discharged from the emergency dissipation device installed in the center of the roof. The structure is such that the energy is released to the outside. This anhydrous gas holder is highly responsive to temporal fluctuations in gas production and consumption, and is also useful for storing blast furnace gas, etc. used in steelmaking, for reasons such as being able to maintain a constant pressure. It is used as equipment in an extremely wide range of industrial fields.

By the way, this conventional gas holder was originally manufactured for the purpose of using each holder individually, so several holders are connected and moved so that each gas inlet and outlet pipe is shared. There were no examples.

That is, in the subordinate piston, gas inlet and outlet pipes were individually provided from the gas generation equipment to each gas holder, and the gas was stored at a pressure corresponding to the weight of each piston.

In other words, gas is first fed into the first gas holder until it is full, then the valve is switched so that gas flows into the second gas holder, and then the gas is sent until it is full. was going on. Similar operations were repeated to receive gas into each gas holder, creating a large-capacity gas storage facility.

In this case, there is an inconvenience that the stored gas pressure also varies in proportion to the variation in the weight of the piston of each gas holder. Furthermore, when discharging gas, the stored gas is taken out from each gas holder so as not to be affected by differences in storage pressure between the gas holders.

Furthermore, as in the past, multiple gas holders, each equipped with a gas dispersion device, are arranged side by side.
Assuming that they are connected to share the gas inlet and outlet pipes and supply gas, gas will flow only into the gas holder with the lightest piston, and once it is full, it will be released from the gas dissipation device to the outside. There is an inconvenience that the file is only sent to other holders and is not forwarded to other holders.

This invention eliminates these inconveniences and makes it possible to use multiple holders as storage equipment forming the same supply chain.In particular, by taking advantage of the advantages and characteristics of the waterless gas holder mentioned above, large capacity gas holders can be used. The purpose of this invention is to provide a type of anhydrous gas holder collective storage facility that can store gas at a constant pressure.

The feature of this invention is that multiple units of anhydrous gas holders are connected so as to share each gas inlet and outlet pipe, and the piston load of each holder is increased with a slight difference from the lightest to the heaviest. A gas dissipation device is installed only in the gas holder equipped with a piston, and a piston upper limit control device is installed in each holder except for the gas holder equipped with the heaviest piston. It is designed to be able to be used as a dynamic holder. Furthermore, to specifically explain this based on an example, in the example shown in FIG. An example is shown below.

Then, the piston load of each holder is set such that the load of the piston IA of the first gas holder A from the left is the minimum, and the weight of the pistons of the second and subsequent groups in the right direction is increased with a slight difference, and then the heaviest piston 10 A gas dissipation device 2 is installed in the center of the roof of the third gas holder C equipped with a
and 3B.

The gas dissipation device 2 has the same structure as a water seal device commonly used in the past, and when the piston IC rises to the permissible limit height, the water seal is automatically cut to allow gas to escape from there. The structure is such that it escapes to the outside.
Further, the piston upper limit control devices 3A and 3B are so-called piston stoppers, and have a structure in which a stopping arm, assisted by a portion of the pistons IA and IB, extends from the top inner periphery of the peripheral wall of the holder body. be.

Since the present invention has the configuration as described above, when gas is guided from the gas inlet/output pipe 11, the gas first flows into the gas holder A equipped with the lightest piston IA.

In other words, since the load on the piston IA of gas holder A is lighter than the load on the pistons IB and IC of the other holders B and C, that piston IA rises first, and the V supplied to the lower part of it rises.
Feed gas is stored. Then, when the piston IA of this gas holder A rises and reaches the top, that is, when the holder A is filled, the piston IA is regulated by the upper limit control device 3A.

Therefore, when further gas is transferred from the inlet/outlet pipe 11, since the first gas holder A equipped with the lightest piston is full, it is automatically introduced into the next second gas holder B. be done.

That is, gas holder C equipped with the heaviest piston
Since piston IC is heavier than piston IB of holder B, the piston IB of gas holder B, which has a lighter load, is pushed up and the piston IB of gas holder B, which has a lighter load, is pushed up and
As in the case of the first gas holder A, gas is introduced until the holder B is full.

Hereinafter, gas is introduced into the gas holder C equipped with the heaviest piston IC as described above, and when the piston IC of that holder C rises to the permissible limit, the gas dissipation device 2 is automatically activated. From there it is released to the outside.

As can be understood from the above explanation, if multiple holders are connected according to the method of the present invention, the multiple holders can be used as storage equipment of the same series, especially for large-capacity gas. produced with time-varying differences.
It is extremely advantageous as a storage facility for gases related to steel manufacturing.

Here, the pressure of the gas filled in the gas holder equipped with the lightest piston and the pressure of the gas filled in the gas holder equipped with the heaviest piston vary in proportion to the difference in the piston loads of each holder. However, the effect on equipment that uses gas is almost negligible.

In other words, it is possible to maintain the stored gas pressure at a nearly constant pressure, and it is possible to deal with temporal fluctuations in the gas production and consumption of this anhydrous gas holder, or to connect each holder to the same supply/discharge system. This system satisfies the requirements such as equalizing quality fluctuations caused by gas consumption and securing pressure on the gas consumption side, and as mentioned above, it has an optimal configuration as a large-capacity gas storage facility.
