Amendment July 22, 1981 The name of the invention is amended as follows. Title of the invention: Dehumidifying device The scope of the claims for utility model registration and the brief description of the drawings are amended as follows.

[Claim for Utility Model Registration] Two processing systems in which a dehumidification tower filled with an adsorbent is interposed between a supply pipe that supplies untreated gas containing moisture and a takeoff pipe that takes out dehumidified gas. The untreated gas is pressurized by connecting the pipes in parallel and connecting both processing pipes with a bypass pipe equipped with a flow rate regulator such as a throttle valve or orifice on the take-out pipe side of each dehumidification tower. The untreated gas is passed through one of the dehumidification towers by alternately supplying the untreated gas to each of the treatment pipes for a certain period of time by switching a switching valve installed on the upstream side of each of the dehumidification towers of each of the treatment pipes. At the same time, a part of the dehumidified gas flowing out into the take-out pipe is depressurized through the bypass pipe and supplied to the other humidification tower, and the adsorbent in the dehumidification tower is dehydrated. In a dehumidifying device configured to perform regeneration, the exhaust gas used for regeneration is normally released into the atmosphere through an exhaust pipe leading to a muffler, and the pressure of the exhaust gas generated when the switching valve is switched is controlled. A dehumidifying device characterized by having a normally open relief valve that closes when the valve rises.

Claims (1)

[Scope of utility model registration request] Two processing pipes, each with a dehumidifying tower filled with a moisture absorbent, are connected in parallel between a supply pipe that supplies untreated gas containing moisture and an extraction pipe that takes out dehumidified gas. Both processing pipes are connected on the take-out pipe side of each dehumidification tower by a bypass pipe equipped with a pressure reducer such as a throttle valve, and the pressurized untreated gas is transferred to the upstream side of each dehumidification tower of each processing pipe. By switching the switching valve installed on the side, the untreated gas is alternately supplied to each of the processing pipes for a certain period of time, so that the untreated gas is passed through one of the dehumidification towers and flows out to the takeout pipe, and the untreated gas is also supplied to the takeout pipe. In a dehumidification device, a part of the dehumidified gas flowing out is depressurized through the bypass pipe and supplied to the other dehumidification tower, and the moisture absorbent in the dehumidification tower is dehydrated and regenerated, and used for regeneration. A normally open relief valve is provided in the exhaust pipe that leads the exhaust gas to the muffler, which normally releases the exhaust gas to the atmosphere and closes when the pressure of the exhaust gas increases when the switching valve is switched. A dehumidifying device characterized in that a dehumidifying device is provided.
