摘要： PURPOSE:To enhance the adsorbing capacity of an adsorbing tower and to increase a gas adsorbing rate. CONSTITUTION:In an adsorbing tower wherein a container 1 is packed with a granular adsorbent 4, a cylindrical body 5 for a gas passage is provided in an adsorbent bed or cartridges are vertically received in the container over a plurality of stages and the cylindrical body 5 for the gas passage is provided in the adsorbent beds formed within the cartridges to form a plurality of upper and lower sections within the container and adsorbent beds 1 are formed within these sections and gas can be introduced into the upper section from the periphery thereof. The uppermost part of the adsorbent beds received over a plurality of stages is covered with a net to hold the upper surface of the adsorbent in the inside container to a horizontal surface even when the adsorbing tower is inclined on the way of transport.

摘要： PURPOSE:To decrease pressure changes in a sealed vessel, preventing chemical substances from leaking to the atmosphere, by connecting a communicating pipe leading to the atmosphere to a sealed vessel, interposing a mechanism of reaction and adsorption in the communicating pipe through a sealing mechanism. CONSTITUTION:Heating and cooling treatment can be applied to a chemical substance (a) in a container 2 by heating or cooling the atmosphere within a sealed vessel 11 by means of a heat exchanger 3. For example, when the inside of the sealed vessel 11 is heated to 50 deg.C from normal temperature, the pressure inside the sealed vessel 11 increases by about 60mmHg. However, the pressure acts on the sealing liquid in sealing mechanism 16, 18 through a communicating pipe 15, where the displacement h, h' of the sealing liquid b, b corresponds to the pressure, and in the case of a decrease in pressure in the sealed vessel 11, action similar to that state above takes place, so that the increase and decease in pressure in the sealed vessel 11 is greatly lessened. At the same time, gases containing chemical substance (a), etc., in the sealed vessel 11 are confined, preventing the gas from leaking to the open air.
