Novel adsorption device tower for coal mine gas concentration

Abstract

The invention discloses a novel adsorption device tower for coal mine gas concentration. The adsorption tower includes multiple sections of freely combinable cylinder structures. A gas inlet formed in the lower end of an adsorption tower body is provided with a conical flow distributing part, and a metal net is arranged at the upper portion of a flow distributor and can evenly distribute raw material gas. Multiple layers of metal nets for outputting static electricity and supporting bodies are arranged in the adsorption tower body and are fixed to the adsorption tower body. An exhaust gas discharging port, a gas outlet and an explosion door are arranged in the upper end of the adsorption tower body. A combination of a press plate bottom, a spring and a press plate top is arranged in the upper end of the adsorption tower body and used for applying an appropriate pressure to an adsorbent. The novel adsorption device tower overcomes the shortcomings of the prior art, and the height of the freely combinable adsorption tower can be adjusted according to different types of adsorbents, the concentration and humidity of different types of raw material gases and the parameter requirements of finished products gases to meet the demand for gas concentration under the condition of complicated and varied parameters.

Description

technical field [0001] The invention relates to the technical field of coal resource excavation and reasonable utilization equipment, and in particular belongs to a novel adsorption equipment tower for thickening coal mine gas. Background technique [0002] As an associated resource of coal mining, coal mine gas is flammable and explosive, which seriously affects the safety of coal mine production. Coal mine gas contains a large amount of methane, which is a greenhouse gas. A large amount of gas extracted from coal mines is directly discharged into the atmosphere, which will cause a greenhouse effect on the earth and cause serious pollution to the environment. Coal mine gas is an efficient and clean energy, and direct emission to the air is a huge waste of energy. Scientific control and effective comprehensive utilization of gas, among which, for gas concentration, the adsorption tower is the key equipment of the pressure swing adsorption process, and the design of its inte...

AI Technical Summary

Problems solved by technology

[0003] In the existing adsorption production process, due to the change of the concentration of the raw material gas and the composition ratio of various gases, the ambient temperature such as temperature is also changing, and sometimes the properties of different batches of adsorbents also have certain differences. Therefore, the fixed structure and capacity It is difficult for the adsorption tower to adapt to the changes of the above parameters. As a result, there may be more adsorption materials than the actual demand. At this time, the airflow resistance is large, the production efficiency is low, and the cost is high; the adsorption material configuration may also be less than the actual demand. At this time, exhaust gas emissions and product gas may not meet the expected requirements.

The main reason for the above phenomenon is that the adsorption tower has a fixed capacity and cannot adapt to the changes of various parameters in the adsorption production process.
