料等の用途に供される。Within a steelworks, hydrogen, carbon monoxide, etc. are produced using byproduct gas as raw materials using PSA equipment.This type of equipment has multiple gas adsorption towers, and each gas adsorption tower performs adsorption and pressure equalization. Processing is carried out in a cycle of pressure reduction, cleaning, equalization, and pressure increase, and the cycles of the plurality of gas adsorption towers are shifted from each other so that adsorption is always performed in one of the adsorption towers, and In each adsorption tower, the separated and purified gas generated from other gas adsorption towers is used for cleaning, pressure equalization, and pressurization in each cycle, and the gas used in this way and the gas generated by cleaning are used as off-gas. It is discharged and is normally used as fuel.

を図る必要がある。However, this off-gas has very large fluctuations in gas amount and calories. Figure 3 shows, as an example, the processing cycle in a hydrogen production facility and the fluctuations in off-gas emissions and calories. The amount of off-gas and calories vary over time. It has fluctuated significantly over time. For this reason, off-gas cannot be directly supplied to the user side through piping, and a buffer tank (holder) is required to equalize the supply amount and calories. However, in a normal tank, fluctuations in calories are directly transmitted to the user, so it is necessary to attach a mixing device to the gas holder to make the gas uniform.

にしたことをその基本的特徴とする。The present invention was made in view of the above-mentioned conventional problems, and provides a method that can equalize the buffer of off-gas discharged from PSA equipment and the gas calories supplied to the user side with less equipment burden. [Means and Embodiments for Solving the Problem] Therefore, the present invention provides a means for solving the problem, in which floating hot blast furnaces, which have been created due to the suspension of blast furnaces and production reduction in recent years, are extremely suitable for storing and mixing off-gas. The basic idea is that this tank is used as an off-gas buffer tank, and has the function of buffing the off-gas supplied to the user and equalizing the gas calories. Features.
以下、本発明を図面に基づいて説明する。Hereinafter, the present invention will be explained based on the drawings.

ある。Figure 1 shows the cross-sectional structure of a blast furnace hot blast furnace. (1) is the combustion chamber, (2) is the heat storage chamber υ, and the upper part of the combustion chamber (1) and the heat storage chamber (2) are connected to the conduit (3). Each chamber is connected to conduits (4) and (5) for introducing or discharging gas. Note that (6) is a hot air pipe led to the blast furnace side.

Combustion is stopped, blown air is introduced into the total heat storage chamber (2) from the direction opposite to the flow of gas, and the air is preheated by heat exchange with the bricks.

で供給するものである。In the present invention, the hot blast stove (A) is used as a buffer tank for off-gas discharged from kPsA equipment. That is, for example, an off-gas piping is connected to a hot air pipe (6) or the like and introduced into the hot air furnace (A), and the off-gas is stored in a high pressure state. Then, a constant supply amount is supplied to the user side from a conduit (5) or the like.

とができる。The gap between the bricks (7) of a hot blast furnace has a volume of about 1500 to 2500 rrL3 in the case of a medium to large blast furnace hot blast furnace.
By using 3 to 4 of these units, sufficient volume can be secured, and the pressure resistance of the hot air stove is designed to be approximately 5μi, so it is possible to store gas at high pressure, and therefore, there is By keeping the off-gas gold under high pressure,
It can fully function as a buffer tank for gas supply and demand.
