Scale type helical-flow air concentrating and separating device

Abstract

The invention discloses a scale type helical-flow air concentrating and separating device. The device comprises an inner cylinder (1), an outer cylinder (2) and a helical panel (3), wherein the helical panel (3), the inner cylinder (1) and the outer cylinder (2) form a helical flow passage (4); the helical panel (3) comprises helical passage short slabs (5), and a gap is arranged at the connection of the helical passage short slabs (5) among the helical passage short slabs (5); on the one hand, air or solid of different densities can be separated by using the inertia force generated in the process of the helical flow of the flow; and on the other hand, the air flow can remain the laminar-flow regime all the time by using the air suction and air blowing phenomena formed by the gaps of the helical flow passage (4) and the helical passage short slabs (5). The invention has the advantages of simple structure and low requirements on the used place, capability of the separation and the concentration of the mixed air of different densities, especially the concentration and the centrifugalization of the binary mixed air having larger density difference. The air concentrating and separating device can process large amount of air with low energy consumption in the process of use.

Description

technical field [0001] The invention relates to a gas separator, in particular to a scale-type spiral flow gas concentration separator, which belongs to the technical field of gas separation devices. Background technique [0002] The separation of mixed gases is generally carried out by physical or chemical methods. Generally, physical methods have higher requirements on temperature, and the temperature needs to be lowered to minus 200°C, which requires higher equipment and site requirements; chemical methods for separating mixed gases require the use of chemical agents, which increases the cost of gas separation. It also has certain requirements for the venue. [0003] Based on the above, it can be seen that for chemical or physical methods, these two hair methods are not suitable on certain occasions. For example, in coal mine production enterprises, it is impossible to install large-scale equipment in underground mines for cooling and other operations. But mines often ...

Problems solved by technology

However, mines often contain a mixture of methane and air. On the one hand, the concentration of methane is too high, which is extremely dangerous for mines; on the other hand, if the air mixed with methane is discharged arbitrarily, limited resources will be wasted.
