Abstract

The present invention relates to an adsorption and moisture removing method for firedamp gas, and an apparatus thereof. According to the present invention, an adsorption tower is arranged on a pipeline between a firedamp gas outlet pipeline and a gas supply pipeline network gas inlet pipeline to carry out a regenerated adsorption and moisture removing treatment for the firedamp gas; the adsorbent comprises at least two adsorbents, and the two adsorbents are placed hierarchically, wherein a mass ratio of the adsorbent in the bottom layer to the adsorbent in the top layer is 5:1-2:1; a regeneration air valve of a high temperature air inlet pipe and an exhausting steam discharge valve of an exhausting steam outlet pipe of the adsorption tower are opened, and high temperature air is introduced to carry out a regeneration treatment for the adsorbents, wherein the adsorption treatment is completed by the adsorption tower. With the present invention, the air is directly heated by the local firedamp combustion with a hot blast stove so as to improve the heat efficiency; the adsorbents are hierarchically placed, such that the flowing direction of the high temperature regeneration air is changed, and the service life of the adsorbent is prolonged; the maintenance and the repair are simple and easy to perform, and the operating cost is low.

Description

technical field [0001] The invention relates to the field of gas dehumidification, in particular to a gas adsorption and dehumidification method and a device thereof. Background technique [0002] During the formation of coal, a large amount of gas adsorbed on the coal body is produced due to high pressure and anaerobic conditions, which is called coalbed methane, also known as "gas", and its main component is methane. During the coal mining process, due to the decompression of the coal body, the equilibrium condition of gas adsorption on the coal body is destroyed, and a large amount of coalbed methane is released, posing the biggest threat to the safety of coal mine production. At the same time, a large amount of water is discharged during the mining of coalbed methane, so the mined coalbed methane will not only contain saturated water vapor, but also carry a part of condensed water. [0003] China is rich in coalbed methane resources. CBM reserves with a storage depth o...
